Description

Technical Field

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

[0002] Cables, 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. Therefore, there are high requirements for the reliability and accuracy of the cables delivered to the electrical components. 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 vehicle to obtain the fuel level based on the sensing signal, thus allowing 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 in the frame. Then, a fixed end of each cable is delivered to each preset cable end of the resistive element, and the corresponding fixed end and preset cable end are welded together and fixed.

[0003] However, in the existing technology, the process of conveying cables to the corresponding positions of workpieces for assembly is either carried out by traditional manual methods, which have extremely low conveying efficiency, or by simple tooling semi-automation methods, which require a high degree of operator involvement. During the process, the operator is prone to bending the cables, which adversely affects the reliability of cable conveying. In particular, for the assembly of multiple cables relative to the same workpiece, the tooling semi-automation method requires manual intervention in the transfer of the relative positions of the workpiece and each cable, making it difficult to ensure that each cable can be assembled with multiple different preset cable ends of the same workpiece with high precision.

[0004] In summary, existing technologies suffer from low efficiency and unreliability in cable transmission. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies in cable delivery, namely low efficiency and unreliability. To achieve one objective of this utility model, a cable clamping and positioning device is provided, comprising: a wiring mechanism including a wiring plate, a wiring groove, a support block, and a third driving cylinder; the wiring plate has a wiring groove for receiving cables; the support block is located above the third driving cylinder; the wiring plate and the support block are fixedly connected; and the third driving cylinder drives the support block to reciprocate; and a cable pushing mechanism including a second driver and a pair of retaining plates; the second driver drives the pair of retaining plates to fix and push the cable located in the wiring groove.

[0006] Furthermore, the wiring mechanism includes pairs of guide posts disposed on the wiring board, each pair of guide posts restricting the movement of cables passing through the wiring slots between them away from the wiring slots.

[0007] Furthermore, the wire pushing mechanism also includes a retaining block and a pair of drive frames. The pair of retaining plates are respectively fixed on a drive frame. A retaining plate is provided on each side of the retaining block, and a retaining groove communicating with the wiring groove is provided in each retaining plate.

[0008] Furthermore, a retaining block is provided at one end of the terminal block. The cable passes through the retaining groove, the retaining plate, and the retaining block. The second driver is set on the support block. The terminal block is fixedly connected to the support block through the second driver and a fixed post. The second driver drives a pair of drive frames to move a pair of retaining plates relatively close to or away from the side of the retaining block adjacent to them, thereby fixing or releasing the cable position accordingly.

[0009] Furthermore, the second actuator is positioned between the support block and the third drive cylinder, and the fixed column is spaced relative to the second actuator and is further away from the wire pushing mechanism than the second actuator.

[0010] Furthermore, the wiring mechanism also includes a pair of guide ramps fixedly connected to the terminal block, the guide ramps being opposite each other and inclined toward the terminal block.

[0011] To achieve another objective of this utility model, a cable conveying device is provided, comprising: a cable feeding mechanism, which includes a driving component, a cable take-up component, and a limiting component corresponding to the cable take-up component, wherein the cable take-up component is used to receive the cable, and the limiting component limits the position of the cable; and any of the above cable clamping and positioning devices, wherein the driving component drives the cable to move above the wiring slot, and the limiting component releases the limitation on the cable to receive the cable after it falls.

[0012] Furthermore, the drive assembly includes a first drive cylinder and a first drive block connected by a drive, a second drive cylinder and a second drive block connected by a drive, a support, a drive arm, a lifting rod, and a lifting arm. The support is fixedly connected to the first drive block. The first drive cylinder drives the first drive block to reciprocate along a first direction relative to the wiring mechanism, moving closer to or further away from it. The second drive cylinder is mounted on the support. The drive arm is fixedly connected to the second drive block. The lifting rod is fixedly connected to the drive arm. One end of the lifting arm is fixedly connected to the lifting rod, and the other end is initially located in the wiring groove. The take-up assembly includes a take-up block and a baffle. The take-up block has a take-up groove for receiving the cable. The baffle abuts against the front end of the cable and is located at the end of the take-up groove of the take-up block. The limiting assembly 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 can be formed between the limiting clamps to allow a cable to enter. The first driver drives a pair of limiting clamps to move closer to or further away from each other relative to the sides of the adjacent limiting blocks. When they are relatively close, the pair of limiting clamps clamp and fix the cable in the gap. When they are relatively far apart, a gap is formed that allows the cable to pass through. The drive arm is fixedly connected to the first driver. After the pair of limiting 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. Thus, the limiting 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 the wiring mechanism along the first direction. The first direction is perpendicular to the second direction. After the cable is above its corresponding wiring slot, the first driver drives the pair of limiting clamps to move away from each other, so that the cable falls into the wiring slot.

[0013] Furthermore, when the wiring mechanism is located at the initial wiring position corresponding to the cable after it has been received in the wiring slot, and the second driver drives a pair of retaining plates to move relatively close to each other so that the cable position is kept fixed, the third drive cylinder drives the wiring plate and the wire pushing mechanism to move away from the wire feeding mechanism, thereby moving the wiring mechanism to the cable receiving position. After the cable is received, the second driver drives a pair of retaining plates to move relatively away from each other so that the cable position is released from fixation, and the third drive cylinder drives the wiring plate and the wire pushing mechanism to move towards the wire feeding mechanism to return to the initial wiring position.

[0014] Furthermore, there are two cable delivery mechanisms, two connection mechanisms, and two cable push mechanisms, forming two sets of cable delivery modules. Each cable delivery module has the same number of connection slots and take-up slots.

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

[0016] The cable clamping and positioning device and cable conveying equipment provided by this utility model can reliably receive cables through the wiring mechanism and convey cables with high automation and precision through the push mechanism. Therefore, the cable clamping and positioning device of this utility model has the advantages of high efficiency and high reliability in cable conveying. Attached Figure Description

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 8 As an objective of this utility model, a cable clamping and positioning device is provided, which is applied in a cable conveying equipment. For the sake of completeness of description and understanding, the cable clamping and positioning 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 mechanism 1, a cable clamping and positioning device, a clamping mechanism 4, and a clamping mechanism 5. The cable feeding mechanism 1 includes a drive component 11, a take-up component 12, and a limiting component 13 corresponding to the take-up component 12. The take-up component 12 is used to receive the cable 20, and the limiting component 13 limits the position of the cable 20. The cable clamping and positioning device includes a wiring mechanism 2 and a pushing mechanism 3. The wiring mechanism 2 includes a wiring groove 211. The drive component 11 drives the cable 20 to move above the wiring groove 211, and the limiting component 13 releases the limitation on the cable 20 so that the wiring groove 211 receives the cable 20 after it has fallen. (Refer to reference) Figure 5Specifically, the wiring mechanism 2 includes a wiring plate 21, a support block 23, and a third drive cylinder 24. The wiring plate 21 has a wiring groove 211. 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. The wire pushing mechanism 3 includes a second driver 31 and a pair of retaining plates 33. The second driver 31 drives the pair of retaining plates 33 to fix and push the cable 20 located in the wiring groove 211. In this way, each cable 20 located on the wiring plate 21 is not only reliably positioned by the wiring groove 211, but can also be accurately conveyed by the third drive cylinder 24. 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 invention, the workpiece is a liquid level sensor. Figure 8 The diagram illustrates a liquid level sensor to which the cable is to be welded. The liquid level sensor includes a frame 30, a resistive element 30 mounted within the frame 40, and a cable 20 welded onto the resistive element. 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 positioned 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 relative to the resistive element 30 by varying the buoyancy of, for example, 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 wiring mechanism 2 of the cable clamping and positioning device provided in this embodiment can reliably receive the cable 20 transported and dropped by, for example, the cable feeding mechanism 1, and the cable pushing mechanism 3 can automatically and accurately transport the cable 20. Thus, the cable clamping and positioning device provided in this invention has the advantages of high efficiency and high reliability in cable transport.

[0030] Please refer to the reference. Figure 5 Preferably, the wiring mechanism 2 further includes pairs of guide posts 22 disposed on the wiring plate 21. The number of pairs of guide posts 22 can be set to be the same as the number of wiring slots 211. The guide posts 22 restrict the movement of the cable 20 in the wiring slots 211 passing through them in the second direction. Therefore, the cable 20 can be better positioned in the wiring slots 211.

[0031] Please refer to the reference. Figure 5Specifically, the wire pushing mechanism 3 also includes a retaining block 32 and a pair of drive frames 34. A 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 is provided with a retaining groove 331 that communicates with the wiring groove 211. For example, if the wiring groove 211 and the take-up groove 1211 (which will be described in further detail below) are both provided as two, and two vertical planes parallel to the first direction pass through a pair of wiring grooves 211 and take-up grooves 1211 respectively, the wiring plate 21 is provided with a retaining block 32 at one end closer to the wire clamping mechanism 4, and the cable 20 passes through the retaining groove 331, the retaining plate 33, and the retaining block 32. The second driver 31 is mounted on the support block 23. The terminal block 21 is fixedly connected to the support block 23 via the second driver 31 and the fixing post 25. 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 accordingly. Alternatively, if both the terminal slot 211 and the take-up slot 1211 are set to one, and a vertical plane parallel to the first direction passes through a take-up slot 1211 and a take-up slot 1211 respectively, each of the pair of retaining plates 33 has a retaining groove 331 facing 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 accordingly. Therefore, the cable 20 can be reliably fixed by the holding plate 33 during the pushing process of the cable pushing mechanism 3, and the fixing of the cable is released after the cable is pushed into place so that the cable can be further transported to other positions by the clamping mechanism 4.

[0032] More specifically, for both the wiring slot 211 and the take-up slot 1211, there may be two or one. When the wiring mechanism 2 is located at the initial wiring position corresponding to the cable 20 after it has been received in the wiring slot 211, and the second driver 31 drives the 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 wiring plate 21 and the pusher mechanism 3 to move towards the clamping mechanism 4, so that the wiring mechanism 2 moves to the clamping receiving position. After the cable 20 is clamped by the clamping mechanism 4, the second driver 31 drives the 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 wiring plate 21 and the pusher mechanism 3 to move away from the clamping mechanism 4 and return to the initial wiring position.

[0033] 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 wiring slot 211 of the connector 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 wiring slot 211 of the connector plate 21 are both provided as two. Therefore, the cable pushing mechanism 3 uses a pair of retaining plates 33 to maintain and release the position of the cable 20.

[0034] Please refer to the reference. Figure 5 Preferably, the second driver 31 is disposed between the support block 23 and the third drive cylinder 24, and the fixed column 25 is spaced apart from the second driver 31 and is further away from the wire pushing mechanism 2 than the second driver 31. Therefore, the overall structure of the cable clamping and positioning device is compact.

[0035] Please refer to the reference. Figure 5 Preferably, the wiring mechanism 2 further includes a pair of guide ramps 26 fixedly connected to the wiring plate 21, the two guide ramps 26 being opposite to each other and inclined toward the wiring plate 21. In this way, the cable 20 can be accurately slid into the wiring slot 211 of the wiring plate 21 by being guided by the guide ramps 26.

[0036] Please refer to the reference. Figure 3 and Figure 4Specifically, the drive assembly 11 of the wire feeding mechanism includes a first drive cylinder 111 and a first drive block 112 connected by a drive, a second drive cylinder 113 and a second drive block 114 connected by a drive, a support 115, a drive arm 116, a wire lifting rod 117 and a wire lifting arm 118 connected by a drive. 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 relative to the wiring mechanism 2, moving closer to or further away from it. The second drive cylinder 113 is disposed on the support 115. The drive arm 116 is fixedly connected to the second drive block 114. The wire lifting rod 117 is fixedly connected to the drive 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 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 receiving the cable. The baffle 122 abuts against the front end of the cable 20 and is located at the end of the take-up block 121 away from the take-up groove 1211. 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 approach or move 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 located 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. After the pair of limit clamps 133 have clamped and fixed the cable 20, the second drive cylinder 113 drives the second drive block 114 to move the drive arm 116 upward along the second direction, so that the limit clamps 133 and the lifting arm 118 jointly lift the cable 20 away from the take-up slot 1211. The first drive cylinder 111 then drives the first drive block 112 to move the support 115 toward the wiring mechanism 2 along the first direction, which is perpendicular to the second direction. After the cable 20 is above its corresponding wiring slot 211, the first driver 131 drives the pair of limit clamps 133 to move away from each other, so that the cable 20 falls into the wiring slot 211. In this way, the pair of limit clamps 133 of the cable feeding mechanism 1 can reliably clamp and release the cable 20 and accurately move above the corresponding wiring slot 211 under the drive of the corresponding drive cylinder, so that the wiring slot 211 accurately receives the falling cable 20.

[0037] 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.

[0038] 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-passing groove 41011 that communicates with the wire threading hole. The number of wire threading holes and wire-receiving grooves 1211 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 threading hole and enters the corresponding wire clamping through hole under the drive of the third drive cylinder 24. Each wire threading hole is equipped with a wire threading detector 4102, which detects whether the cable 20 has accurately passed through the wire threading hole. Therefore, the wire threading assembly 410 can further ensure that the cable 20 accurately passes through the wire threading hole and enters the wire clamping through hole.

[0039] 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.

[0040] Please refer to the reference. Figure 1 , Figure 2 and Figure 8 Specifically, 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 provided in pairs, and each of these different mechanisms constitutes a cable conveying module. There are two cable conveying modules. 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.

[0041] 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 clamping and positioning devices described above. The cable conveying device comprises multiple different workstations for conveying cables, with the cable clamping and positioning devices correspondingly located at the middle workstations. The cable conveying device can achieve the beneficial effects of any of the cable clamping and positioning devices, which will not be elaborated further here. Therefore, by conveying the cables 20 above the pre-assembled resistors 30 in the frame 40 through the cable conveying device, and assembling the fixed ends (i.e., conductive ends) of each cable with the preset cable ends of the resistors 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.
