Description

Technical Field

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

[0002] Cables, used as a medium for transmitting current or signals, are widely used in many workpieces with electrical components. The reliability and accuracy achieved by assembling cables using methods such as soldering are crucial for the high-quality operation of the workpiece, thus placing high demands on the reliability and accuracy of the cables delivered to the workpiece. Taking an existing contact-type liquid level sensor as an example, it utilizes contacts on a spring that can rotate relative to a resistive element to change the resistance value, thereby outputting a sensing signal. Liquid level sensors are generally installed in the fuel tank of a gasoline-powered vehicle, obtaining the fuel level based on the sensing signal, which is then used by the vehicle's fuel gauge to indicate the fuel level accordingly. The liquid level sensor includes cables, a frame, and a resistive element. The resistive element is first assembled within the frame. Then, a fixed end of each cable is delivered to each preset cable end of the resistive element, and the corresponding fixed ends and preset cable ends are welded together and fixed in place.

[0003] However, in the existing technology, when transporting cables to the corresponding positions of the workpiece for assembly, either traditional manual methods are used, which have extremely low transport efficiency, or simple tooling semi-automatic methods are used, which still require a large degree of operator involvement. Moreover, during the process, it is not easy for the operator to load and position the specified number of cables well, which adversely affects the reliability and accuracy of cable transport, resulting in the inability to assemble the cables onto the workpiece with high quality.

[0004] In summary, existing technologies suffer from low accuracy in cable feeding and low positioning precision. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies in cable feeding, such as low accuracy and poor positioning precision. To achieve one objective of this utility model, a cable feeding device is provided, comprising: a take-up assembly for receiving cables; a drive assembly for driving the cable movement, the drive assembly including a first drive cylinder and a first drive block connected by a drive, and a support, the support being fixedly connected to the first drive block, the first drive cylinder driving the first drive block to reciprocate along a first direction to drive the cable movement; and a limiting assembly corresponding to the take-up assembly for limiting the received cable at a predetermined position.

[0006] Furthermore, the drive assembly also includes a second drive cylinder and a second drive block, a drive arm, a lifting rod, and a lifting arm, all connected by a drive connection. The second drive cylinder is mounted on a support, the drive arm is fixedly connected to the second drive block, and the lifting rod is fixedly connected to the drive arm.

[0007] Furthermore, the take-up assembly includes a take-up block and a baffle. The take-up block has a take-up groove for storing the cable, and the baffle is located at the end of the take-up groove of the take-up block. The baffle is used to block the front free end of the cable. One end of the lifting arm is fixedly connected to the lifting rod, and the other end is initially located in the groove of the take-up block that is recessed relative to the take-up groove.

[0008] Furthermore, the limiting assembly also includes a first driver, a limiting block, and a pair of limiting clamps located opposite each other on both sides of the limiting block. A gap for a cable to enter can be formed between the limiting block and the adjacent limiting clamps. The first driver drives the pair of limiting clamps to move closer to each other or further away from each other relative to the sides of the adjacent limiting block. When they are relatively close, the pair of limiting clamps clamp and fix the cable located in the gap. When they are relatively far apart, a gap is formed that allows the cable to pass through. The driving arm is fixedly connected to the first driver.

[0009] Furthermore, after a pair of limit clamps have clamped and fixed the cable, the second drive cylinder drives the second drive block to move the drive arm upward along the second direction, so that the limit clamps and the lifting arm jointly lift the cable away from the take-up slot. The first drive cylinder then drives the first drive block to move the support towards a preset slot for receiving the cable along the first direction. The first direction is perpendicular to the second direction. After the cable is above the preset slot, the first driver drives the pair of limit clamps to move away from each other, so that the cable falls into the preset slot.

[0010] Furthermore, the take-up trough includes a take-up inclined trough and a take-up flat trough. Under its own gravity, the cable is guided by the take-up inclined trough to the take-up flat trough until the front free end abuts against the baffle.

[0011] Furthermore, the cable feeding device also includes an air blowing mechanism located behind the take-up block. The air blowing mechanism blows air toward the take-up trough, thereby causing the front free end of the cable in the take-up trough to abut against the baffle.

[0012] Furthermore, the cable feeding device also includes a CCD camera located above the take-up trough, which is used to identify the color of the cable and the position of the front free end.

[0013] To achieve another objective of this utility model, a cable conveying device is provided, including any of the above-mentioned cable feeding devices.

[0014] Furthermore, there are two cable feeding devices, and the two cable feeding devices have one and two take-up slots respectively.

[0015] The beneficial effects of this utility model are as follows:

[0016] The cable feeding device and cable conveying equipment provided by this utility model can accurately feed cables through the cable take-up component, accurately position cables through the limiting component, and reliably convey the fed and positioned cables through the driving component, thus achieving high accuracy in cable feeding and positioning.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element limited by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. Unless otherwise specified, embodiments of the present invention and the various features thereof can be combined with each other, all within the protection scope of the present invention.

[0029] refer to Figures 1 to 8As an objective of this utility model, a cable feeding device is provided, which is applied in a cable conveying equipment. For the sake of completeness of description and understanding, the cable feeding device is described below through a detailed description of the various parts of the cable conveying equipment, especially their cooperative operation. The cable conveying equipment includes a cable feeding device 1, a wiring mechanism 2, a wire pushing mechanism 3, a wire clamping mechanism 4, and a clamping mechanism 5. The cable feeding device 1 includes a drive assembly 11, a take-up assembly 12, and a limiting assembly 13 corresponding to the take-up assembly 12. The take-up assembly 12 is used to receive the cable 20, and the limiting assembly 13 limits the position of the cable 20, that is, limits the cable to a predetermined position in the take-up assembly. The wiring mechanism 2 includes a wiring groove 211. The drive assembly 11 drives the cable 20 to move above the wiring groove 211, and the limiting assembly 13 releases the limitation on the cable 20 so that the wiring groove 211 receives the cable 20 after it falls. The wire pushing mechanism 3 is used to fix and push the cable 20 located in the wiring groove 211. The wire clamping mechanism 4 is used to clamp the cable 20 pushed into it by the wire pushing mechanism 3. The clamping mechanism 5 is used to install and clamp the workpiece to which the cable 20 is assembled. In this utility model, the workpiece is a liquid level sensor. Figure 8 The diagram illustrates a liquid level sensor to which the cable is to be soldered. The liquid level sensor includes a frame 30, a resistive element 30 mounted in the frame 40, and a cable 20 soldered onto the resistive element 30. More specifically, the liquid level sensor also includes a rocker arm 50, a spring 60, and a reed 70. The reed 70 is fixed to the rocker arm 50, and the rocker arm 50 is rotatably mounted on the resistive element 30. The spring 60 is arranged between the frame 40 and the rocker arm 50 to apply an elastic force to the relative position of the reed 70 and the resistive element 30. The rocker arm 50 rotates at different angles relative to the resistive element 30 by receiving changes in, for example, the buoyancy of gasoline in a fuel tank, thereby changing the resistance value of the contacts on the reed 70 and achieving the purpose of outputting a sensing signal. Therefore, the cable conveying device provided in this embodiment of the utility model achieves highly automated cable conveying 20 by setting up various related structures that can play corresponding conveying functions in cooperation with each other. In particular, for the cable feeding device 1, the take-up component 12 can feed the cable with high accuracy, the limiting component 13 can position the cable with high precision, and the drive component 11 can reliably convey the fed and positioned cable 20. Thus, the technical effect of high accuracy in cable feeding and high accuracy in positioning is achieved.

[0030] Please refer to the reference. Figure 3 and Figure 4Specifically, the drive assembly 11 includes a first drive cylinder 111 and a first drive block 112 connected by a drive, and a support 115. The support 115 is fixedly connected to the first drive block 112. The first drive cylinder 111 drives the first drive block 112 to reciprocate along a first direction, thereby driving the cable to move. Specifically, the first drive block 112 is driven to reciprocate along the first direction relatively close to or relatively far from the wiring mechanism 2. Therefore, the drive assembly 11 can drive the cable to move with high automation and high efficiency.

[0031] Preferably, the drive assembly further includes a second drive cylinder 113 and a second drive block 114, a drive arm 116, a lifting rod 117, and a lifting arm 118, all connected by a drive mechanism. The second drive cylinder 113 is mounted on a support 115. The drive arm 116 is fixedly connected to the second drive block 114, and the lifting rod 117 is fixedly connected to the drive arm 116. The take-up assembly 12 includes a take-up block 121 and a baffle 122. The take-up block 121 has a take-up groove 1211 for storing cables. One end of the lifting arm 118 is fixedly connected to the lifting rod 117, and the other end is initially located in a groove 1212 on the take-up block 121 that is recessed relative to the take-up groove 1211. The baffle 122 is located at the end of the take-up groove 1211 of the take-up block 121 and is used to abut the front free end of the cable 20. Therefore, the cable 20 can be reliably transported to the next work station while being lifted and not easily rubbing against other components.

[0032] Preferably, the limiting assembly 13 includes a first driver 131, a limiting block 132, and a pair of limiting clamps 133 located opposite each other on both sides of the limiting block 132. A gap for a cable 20 to enter can be formed between the limiting block 132 and the adjacent limiting clamps 133. The first driver 131 drives the pair of limiting clamps 133 to move closer to or further away from each other relative to the sides of the adjacent limiting block 132. When they are relatively close, the pair of limiting clamps 133 clamp and fix the cable 20 in the gap. When they are relatively far apart, a gap is formed that allows the cable 20 to pass through. The driving arm 116 is fixedly connected to the first driver 131. Therefore, the clamping and releasing of the cable can be reliably achieved by driving the limiting clamps 133 with the first driver 131, thereby facilitating the transfer of the cable from one workstation to another.

[0033] Preferably, after the pair of limiting clamps 133 have clamped and fixed the cable 20, the second drive cylinder 113 drives the second drive block 114 to drive the drive arm 116 to rise along the second direction, so that the limiting clamps 133 and the lifting arm 118 jointly lift the cable 20 away from the take-up groove 1211. The first drive cylinder 111 then drives the first drive block 112 to drive the support 115 to move toward the preset groove for receiving the cable along the first direction. In this utility model, the preset groove is the wiring groove 211 provided on the wiring plate 21 of the wiring mechanism 2. The first direction is perpendicular to the second direction. After the cable 20 is above its corresponding wiring groove 211, the first driver 131 drives the pair of limiting clamps 133 to move away from each other, so that the cable 20 falls into the wiring groove 211. In this way, the pair of limit clamps 133 of the cable feeding device 1 can not only reliably clamp and release the cable 20 under the drive of the corresponding drive cylinder with high automation, but also move accurately above the corresponding wiring slot 211, so that the wiring slot 211 can accurately receive the falling cable 20.

[0034] Please refer to the reference. Figure 4 Preferably, the take-up groove 1211 includes a take-up inclined groove 12111 and a take-up flat groove 12112. Under its own gravity, the cable 20 is guided by the take-up inclined groove 12111 to the take-up flat groove 12112 until its front free end abuts against the baffle 122. Therefore, the cable can be guided more accurately from the take-up inclined groove 12111 to the take-up flat groove 12112.

[0035] Preferably, the cable feeding device 1 further includes an air blowing mechanism (not shown) located behind the take-up block. The air blowing mechanism can be a blower, fan, etc., and blows air towards the take-up groove 1211, so that the front free end of the cable in the take-up groove 1211 abuts against the baffle 122. Therefore, by providing the air blowing mechanism, it can be ensured that the front free end of the cable 20 abuts against the baffle 122.

[0036] Preferably, the cable feeding device further includes a CCD camera (not shown) located above the take-up trough. The CCD camera is used to identify the color and position of the front free end of the cable 20. Therefore, by determining the color of the cable 20 through the CCD camera, it can be ensured that the correct cable 20 is placed in the take-up trough 1211, and by determining the condition of the front free end of the cable through the CCD camera, it can be accurately determined whether the front free end of the cable is in contact with the baffle 122, thereby ensuring that the welding part provided at the front free end is subsequently transported to the preset welding position.

[0037] Please refer to the reference. Figure 5Specifically, the wiring mechanism 2 includes a wiring plate 21, pairs of guide posts 22, a support block 23, and a third drive cylinder 24. The wiring plate 21 has wiring slots 211. The number of pairs of guide posts 22 is the same as the number of wiring slots 211. The guide posts 22 restrict the movement of the cables 20 passing through the wiring slots 211 in a second direction. The support block 23 is located above the third drive cylinder 24. The wiring plate 21 and the support block 23 are fixedly connected, and the third drive cylinder 24 drives the support block 23 to reciprocate parallel to the first direction. In this way, each cable 20 located on the wiring plate 21 is not only reliably positioned by the wiring slots 211 and guide posts 22, but can also be accurately conveyed to the clamping mechanism 4 and the mounting mechanism 5 by the third drive cylinder 24.

[0038] Please refer to the reference. Figure 5 Specifically, the wire pushing mechanism 3 includes a second driver 31, a retaining block 32, a pair of retaining plates 33, and a pair of drive frames 34. The pair of retaining plates 33 are respectively fixed on a drive frame 34. A retaining plate 33 is provided on each side of the retaining block 32. Each retaining plate 33 has a retaining groove 331 that communicates with the wiring groove 211. When there are two take-up grooves 1211 and two wiring grooves 211, and two vertical planes parallel to the first direction pass through a pair of take-up grooves 1211 and wiring grooves 211 respectively, a retaining block 32 is provided at the end of the wiring plate 21 closer to the wire clamping mechanism 4. The cable 20 passes through the retaining groove 331, the retaining plate 33, and the retaining block 32. The second driver 31 is set on the support block 23. The wiring plate 21 passes through the second driver 31 and the fixed The column 25 is fixedly connected to the support block 23. The second driver 31 drives a pair of drive frames 34 to move a pair of retaining plates 33 closer to or further away from the side of the adjacent retaining block 32, thereby fixing or releasing the position of the cable 20. Alternatively, when both the take-up groove 1211 and the connection groove 211 are set as one and a vertical plane parallel to the first direction passes through the take-up groove 1211 and the connection groove 211 respectively, the retaining grooves 331 of each of the pair of retaining plates 33 are opposite to each other. The cable 20 passes through the two retaining grooves 331 and then through the pair of retaining plates 33. The second driver 31 drives a pair of drive frames 34 to move a pair of retaining plates 33 closer to or further away from each other, thereby fixing or releasing the position of the cable 20.

[0039] For both take-up slot 1211 and connection slot 211, there may be two or one connection slot. When the connection mechanism 2 is located at the initial connection position corresponding to the cable 20 after it has been received in the connection slot 211, and the second driver 31 drives a pair of retaining plates 33 to move relatively close so that the position of the cable 20 is kept fixed, the third drive cylinder 24 drives the connection plate 21 and the push mechanism 3 to move towards the clamping mechanism 4, so that the connection mechanism 2 moves to the clamping receiving position. After the cable 20 is clamped by the clamping mechanism 4, the second driver 31 drives a pair of retaining plates 33 to move relatively away so that the position of the cable 20 is released. The third drive cylinder 24 drives the connection plate 21 and the push mechanism 3 to move away from the clamping mechanism 4 and return to the initial connection position.

[0040] It should be noted that in this utility model, as described below, there are two cable conveying modules. In one cable conveying module, the take-up slot 1211 of the take-up block 121 and the connection slot 211 of the connection plate 21 are both provided as one. In the other cable conveying module, the take-up slot 1211 of the take-up block 121 and the connection slot 211 of the connection plate 21 are both provided as two. That is to say, in a specific embodiment of the cable conveying equipment, there are two cable feeding devices. Preferably, the two cable feeding devices have one and two take-up slots 1211 respectively, which is particularly suitable for conveying one cable and two cables respectively, and for processing such as welding. Therefore, the pusher mechanism 3 uses a pair of retaining plates 33 to maintain and release the position of the cable 20.

[0041] Please refer to the reference. Figure 6 and Figure 7Specifically, the wire clamping mechanism 4 includes a support plate 401, a first wire clamping plate 402, and a second wire clamping plate 403. The first wire clamping plate 402 has two first wire clamping half-holes 4021, and the second wire clamping plate 403 has two second wire clamping half-holes 4031. The first wire clamping half-holes 4021 and the second wire clamping half-holes 4031 are arranged alternately opposite to each other. The first wire clamping plate 402 and the second wire clamping plate 403 are elastically connected to the support plate 401 through a first elastic member 404. Under the action of the first elastic member 404, the first wire clamping plate 402 and the second wire clamping plate 403 are initially separated from each other, thus forming a first wire passage groove 405 between the two adjacent first wire clamping half-holes 4021 and second wire clamping half-holes 4031. A guide roller 406 is provided on the outer side of the first wire clamping plate 402 and the second wire clamping plate 403, respectively. A first guide rail 407 is provided on the support plate 401. A first guide block 408 that is slidably connected to the first guide rail 407 is provided on the first wire clamping plate 402 and the second wire clamping plate 403 respectively. A pressure plate 409 is fixed on each of the two outer surfaces of the support block 23. When the third drive cylinder 24 drives the support block 23 to move parallel to the first direction toward the wire clamping mechanism 4, the two pressure plates 409 press against a guide roller 406 respectively. The first wire clamping plate 402 and the second wire clamping plate 403 respectively overcome the elastic force of the corresponding first elastic member 404 and abut against each other. Thus, each pair of adjacent first wire clamping half hole 4021 and second wire clamping half hole 4031 forms a wire clamping through hole. At the same time, the third drive cylinder 24 drives the cable 20, which is held in position by a pair of retaining plates 33, to pass through the wire clamping through hole and be clamped in the wire clamping through hole. In this way, the first clamping plate 402 and the second clamping plate 403 can clamp and release the cable in conjunction with the movement of the pressure plate 409, thereby facilitating the transport of the cable and its subsequent transfer with the workpiece.

[0042] Please refer to the reference. Figures 5 to 7 Specifically, the wire clamping mechanism 4 further includes a wire threading assembly 410, which is located between the two wire clamping plates and the terminal block 21. The wire threading assembly 410 includes a wire threading block 4101, a wire threading detector 4102, and a fourth drive cylinder 4103. The wire threading detector 4102 can be an infrared detector. The wire threading block 4101 has a second wire passage groove 41011 aligned with the wire clamping through hole. The number of wire clamping through holes and the number of terminal passage grooves 211 are the same. The fourth drive cylinder 4103 drives the wire threading block 4101 to rise and fall to ensure that the cable 20 passes through the wire clamping through hole and enters the corresponding wire clamping through hole under the drive of the third drive cylinder 24. Each wire clamping through hole is equipped with a wire threading detector 4102, which detects whether the cable 20 has accurately passed through the wire clamping through hole. Therefore, the wire threading assembly 410 can further ensure that the cable 20 accurately passes through the wire clamping through hole and enters the wire clamping through hole.

[0043] Please refer to the reference. Figure 2 , Figures 5 to 7Specifically, the clamping mechanism 4 also includes a fifth drive cylinder 411 and a mounting plate 412. The mounting plate 412 has a second guide rail 413 on its first side facing the support plate 401. The support plate 401 has a second guide block 414 that is slidably connected to the second guide rail 413. The fifth drive cylinder 411 drives the support plate 401 to rise and fall to ensure that the cable 20 is accurately inserted into the corresponding clamping through hole. The clamping mechanism 5 includes a third driver 51 and a pair of jaws 52. The third driver 51 is mounted on the second side of the mounting plate 412 away from the first side. The third driver 51 drives the pair of jaws 52 to move closer or further apart. When the pair of jaws 52 are relatively close, they can be used to clamp a workpiece to assemble the cable 20 onto the workpiece. When the cable 20 is assembled onto the workpiece, the pair of jaws 52 move further apart, thereby relaxing the workpiece so that it can be transferred. In this way, a pair of jaws 52 can reliably clamp the workpiece to ensure that the cable 20 is assembled on the workpiece, and can also automatically release the workpiece so that the workpiece with the cable 20 assembled can be transferred to another cable conveying module in a timely manner by, for example, other transfer mechanisms.

[0044] Please refer to the reference. Figure 1 , Figure 2 and Figure 8 Specifically, each of the cable feeding device 1, the wiring mechanism 2, the wire pushing mechanism 3, the wire clamping mechanism 4, and the clamping mechanism 5 is configured in pairs, and each of these different mechanisms constitutes a cable conveying module. There are two cable conveying modules, and the number of take-up slots 1211 in the two cable feeding devices of the two cable conveying modules is preferably one and two, respectively. It should be noted that the embodiments of this utility model are all described using two cable conveying modules as an example. This allows for the assembly of, for example, one or two cables 20 on both sides of the resistive element 30 of the liquid level sensor relative to the workpiece by welding, thereby achieving high cable assembly efficiency.

[0045] As another objective of this utility model, it also provides a cable conveying device for welding cables for liquid level sensors. This device includes any of the cable feeding devices described above. The cable conveying device comprises multiple different workstations for conveying cables, with the cable feeding device correspondingly located at the initial cable workstation. The cable conveying device can achieve the beneficial effects of any of the cable feeding devices, which will not be elaborated further here. Therefore, by conveying the cable 20 to the resistor 30 already assembled in the frame 40 through the cable conveying device, and assembling the fixed end (i.e., the conductive end) of each cable with the preset cable end of the resistor 30 using electrical contacts such as soldering, the liquid level sensor can obtain power and output sensing signals through each cable 20. This method has the advantages of high cable conveying efficiency and high assembly reliability and accuracy.
