Description

Technical Field

[0001] The present invention relates to a temperature sensor assembly line, and more specifically, to an assembly line for assembling the end of a wire and a temperature sensor, and also to a method for assembling the temperature sensor and the end of a wire. Background Art

[0002] In the prior art, when the end of a wire is connected to other electronic components by welding, the insulation layer of the end of the wire needs to be stripped off to expose the metal wire inside. These processes are usually completed manually, with low work efficiency and high assembly cost.

[0003] In order to improve work efficiency and reduce assembly costs, the prior art has developed automated equipment to replace manual assembly. However, the existing automated equipment can only strip shorter insulation layers, but cannot strip longer insulation layers. Alternatively, there are automated equipment that can strip longer insulation layers, but after stripping longer insulation layers, the metal wire inside the wire is relatively soft and will sag under the action of gravity, which cannot meet the subsequent process flow. Summary of the invention

[0004] The object of the present invention is to provide a temperature sensor assembly line, which can keep the wire in a predetermined posture when stripping off the longer insulation layer at the end of the wire so as to meet the subsequent automated process flow.

[0005] In order to achieve the above-mentioned purpose, the temperature sensor assembly line of the present invention includes an automated device for stripping the insulation layer of the wire, the automated device further includes a wire feeding mechanism and a first wire stripping mechanism for stripping the outer insulation layer of the first end of the wire, the first wire stripping mechanism includes a first cutter mechanism and a wire stripping clamp, the first cutter mechanism is used to cut the outer insulation layer of the wire or the first end, the wire stripping clamp clamps the first end of the wire and moves along the wire to strip the outer insulation layer of the first end. After the first cutter mechanism cuts off the outer insulation layer of the first end, the wire feeding mechanism reverses to drive the wire to move so as to form a notch at the cutting position, and then the wire stripping clamp clamps the wire at the notch and moves along the wire direction to strip the cut outer insulation layer of the first end.

[0006] In the invention, since a longer outer insulation layer needs to be stripped off, in order to prevent the metal wire in the conductor from sagging under the action of gravity after the outer insulation layer is stripped off and failing to maintain a predetermined posture, thereby failing to meet the requirements of the next process, the automated equipment is provided with a wire stripping clamp to strip the outer insulation layer at the first end to keep the conductor in a predetermined posture, thereby meeting the requirements of the subsequent automated assembly process.

[0007] In one embodiment, the first cutter mechanism is configured to cut off the outer insulation layer of the first end of the wire in a first state and to cut off the wire in a second state. The first cutter mechanism is used to cut off the outer insulation layer and the wire at the same time, which can reduce the number of parts of the automation equipment compared to using multiple cutter mechanisms.

[0008] In addition, the present invention also relates to an assembly method of a temperature sensor, the assembly method comprising a stripping step of stripping the insulation layer of a wire using an automated device. The automated device comprises a wire feeding mechanism and a first wire stripping mechanism for stripping the outer insulation layer of the first end of the wire, the first wire stripping mechanism comprising a first cutter mechanism and a wire stripping clamp, the first cutter mechanism being used to cut off the outer insulation layer of the wire or the first end; the wire stripping clamp clamps the outer insulation layer of the first end of the wire and moves along the wire to strip the outer insulation layer of the first end. The stripping step further comprises the following steps: the wire feeding mechanism conveys the first end of the wire to the first cutter mechanism; the first cutter mechanism cuts off the outer insulation layer of the first end at a predetermined position of the first end of the wire; the wire or the insulation layer is moved to form a notch at the cutting position of the wire; the wire stripping clamp clamps the wire at the notch and moves along the wire direction to strip the cut outer insulation layer of the first end.

[0009] In another embodiment, the first cutter mechanism moves along the wire conveying direction in a closed state to drive the outer insulating layer to move so as to form a notch at the cutting position. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The structure and other aspects of the temperature sensor assembly line of the present invention are further described in detail below through specific implementations and with reference to the accompanying drawings.

[0021] Figure 1 and Figure 2 They are partial schematic diagrams of the temperature sensor assembly line of the present invention according to one embodiment, and the views mainly show the partial front view and stereoscopic view of the automated equipment used for stripping the insulation layer of the wire in the temperature sensor assembly line of the present invention. The automated equipment includes a wire feeding mechanism 1 and a first wire stripping mechanism 2, the wire feeding mechanism 1 is used to continuously transport the wound wire to other stations of the automated equipment, and the first wire stripping mechanism 2 is used to strip the outer insulation layer of the first end 101 of the wire 10. Specifically, the first wire stripping mechanism 2 further includes a first cutting mechanism 21 and a wire stripping clamp 22, the first cutting mechanism 21 is used to cut off the outer insulation layer of the wire 10 or the first end 101 in different processes, and the wire stripping clamp 22 clamps the first end 101 of the wire and moves along the wire 10 to strip the outer insulation layer of the first end 101.

[0022] In one embodiment, if Figure 3 As shown, the wire feeding mechanism 1 includes one or more rollers 12, which can rotate forward or reversely under the drive of the driving device 13 to feed the wire 10. When the wire feeding mechanism 1 rotates forward, the first end 101 of the wire 10 is fed to the first wire stripping mechanism 2.

[0023] Figure 4 yes Figure 1A partially enlarged stereoscopic view of the first wire stripping mechanism 2 of the automation device shown. In a specific embodiment, the first wire stripping mechanism 2 includes a first cutter mechanism 21 and a wire stripping clamp 22, and the first cutter mechanism 21 is further configured to be used for the outer insulation layer of the first end 101 of the wire 10 in the first state, and to be used to cut the wire 10 in the second state. The wire stripping clamp 22 clamps the first end 101 of the wire 10 and moves along the direction of the wire 10 to strip the outer insulation layer of the first end 101. It should be noted that in this specification, for the convenience of description, the first state and the second state are defined separately, the first state refers to the working state of the automation device before stripping the outer insulation layer of the first end of the wire, and the second state refers to the working state of the automation device when or after stripping the outer insulation layer of the first end.

[0024] In a preferred embodiment, the first cutter mechanism 21 further includes a first upper cutter 211, a first lower cutter 212 and a screw 213. The first upper cutter 211 and the first lower cutter 212 are rotatably mounted on the screw 213. Driven by the screw 213, the first upper cutter 211 and the first lower cutter 212 can move toward or in the opposite direction along the screw 213. In the first state or the second state, the automation device cuts off the wire 10 or the outer insulation layer of the first end 101 of the wire 10 by controlling the different spacings between the first upper cutter 211 and the first lower cutter 212.

[0025] In a specific embodiment, the wire stripping clamp 22 includes a clamping nozzle 221, and the clamping nozzle 221 can be opened and closed under the drive of the driving device. The wire stripping clamp 22 is installed on the slide rail 223 and can move along the slide rail 223 under the drive of the driving device. Figure 4 As shown, a cutting notch 222 is provided near the clamping nozzle 221 on the wire stripping clamp 22. In the first state, the first upper cutting knife 211 and the first lower cutting knife 212 can extend into the cutting notch 222. Thus, in the first state, the clamping nozzle 221 is located upstream of the first cutting knife mechanism 21 along the conveying direction of the wire 10. Figure 5a In the second state, the nozzle 221 is located downstream of the first cutting mechanism 22 along the conveying direction of the wire 10, as shown in FIG. Figure 5b As shown, it is located on the right side of the first cutting mechanism 21.

[0026] The following will refer to Figure 5a and Figure 5b The detailed process of stripping the outer insulation layer of the first end 101 by the automated equipment is described in detail.

[0027] When the automation equipment is working, the wire feeding mechanism 1 feeds the wire 10 of a predetermined length under the action of the roller 12. At this time, the first cutter mechanism 21 is in an open state, and the wire stripping clamp 22 moves along the slide rail 223 so that the clamping nozzle 221 passes through the opening between the first upper cutter 211 and the first lower cutter 212, so as to be located upstream of the first cutter mechanism 21 along the conveying direction of the wire 10, that is, Figure 5a As shown, it is located on the left side of the first cutting mechanism 21. The end position of the wire stripping clamp 22 makes the cutting notch 222 basically located in the same plane as the first upper cutting knife 211 and the first lower cutting knife 212 in the vertical direction. Then the first cutting mechanism 21 is closed, and the first upper cutting knife 211 and the first lower cutting knife 212 are located in the cutting notch 222, as shown in FIG. Figure 5a At this time, the first cutter mechanism 21 is working in the first state, and the closing distance of the first cutter mechanism 21 enables it to be used just to cut off the outer insulation layer of the first end 101 of the wire 10 .

[0028] In one embodiment, after the first cutter mechanism 21 cuts off the outer insulation layer of the first end 101, the first cutter mechanism 21 remains in a closed state and the wire feeding mechanism 1 is reversed by a small distance, thereby forming an insulation layer gap at the position where the outer insulation layer of the first end 101 is cut off, that is, the cut outer insulation layer is stripped from the first end 101 by a small distance through the reversal of the wire feeding mechanism 1, and the distance is slightly larger than the width of the clamping mouth 221. In other embodiments, the wire feeding mechanism 1 may be kept from rotating and the first cutter mechanism 21 in a closed state may be moved by a small distance along the wire feeding direction of the wire 10, thereby forming an insulation layer gap at the position where the outer insulation layer of the first end 101 is cut off.

[0029] Then, the clamping nozzle 221 of the wire stripping clamp 22 is closed and clamped at the above-mentioned notch, the first cutting mechanism 21 is opened, and the wire stripping clamp 22 moves along the slide rail 223 toward the wire feeding direction, so that the clamping nozzle 221 passes through the opening between the first upper cutting knife 211 and the first lower cutting knife 212, thereby moving to the downstream of the first cutting mechanism 21 along the conveying direction of the wire 10, that is, Figure 5b The first cutter mechanism 21 is shown as being located on the right side. In this way, the outer insulation layer of the first end 101 of the wire 10 is stripped off.

[0030] In the present invention, since a relatively long outer insulation layer needs to be stripped, in order to prevent the metal wire in the conductor from sagging under the action of gravity after the outer insulation layer is stripped, and from being unable to maintain a predetermined posture, thereby failing to meet the requirements of the next process, the automation equipment solves this problem by providing a wire stripping clamp 22 to strip the outer insulation layer of the first end. The following will describe in detail how the conductor 10 is processed in the next process after the outer insulation layer of the first end 101 is stripped.

[0031] In a specific embodiment, Figure 1 and 5a As shown, the automation equipment further includes a first clamp (clamping mechanism) 3, which is used to clamp the second end 102 of the wire 10 and send the cut wire 102 to the second cutter mechanism 4 (described in detail below). The first clamp 3 is arranged between the first cutter mechanism 21 and the wire stripping clamp 22. After the wire stripping clamp 22 completely strips the outer insulation layer of the first end 101, the first end 101 of the wire 10 sags under the action of gravity and is located between the clamping mouths 31 of the first clamp 3. After the wire feeding mechanism 1 continues to feed the wire 10 of a predetermined length, the first clamp 3 clamps the wire 10, and the first cutter mechanism 21 is closed to cut the wire 10 to form the second end 102 of the wire 10. The first clamp 3 transports the wire 10 directly or indirectly to the second clamp 5 and then returns to the initial position to transport the next section of the cut wire, which is then transported by the second clamp 5 to the second cutting mechanism 4 to strip off the outer insulation layer and the inner insulation layer of the second end 102. Adding the second clamp 5 can improve the working efficiency of the temperature sensor assembly line of the present invention.

[0032] In a preferred embodiment, Figure 5c As shown, the automation equipment further includes a transfer transmission mechanism 6, which includes, for example, a fixture 61 and a slide rail 62. The fixture 61 can move back and forth along the slide rail 62 under the action of the driving mechanism. The first fixture 3 conveys the cut wire 10 to the transfer transmission mechanism 6, which then conveys it to the second fixture 5. This hand-to-hand sequential transmission action can further improve the working efficiency of the automation equipment on the one hand, and can also cope with long-distance transmission between the first fixture 3 and the second fixture 5 on the other hand.

[0033] In a preferred embodiment, Figure 6 As shown, the automation equipment also includes a calibration device 7 for calibrating the posture of the second end 102 of the wire 10, and the calibration device 7 includes a collection device 71 and a judgment device 72. The collection device 71 is used to collect the posture data of the second end 102 of the wire 10, and the judgment device 72 judges the posture of the second end through the collected data to determine whether the posture of the second end needs to be corrected. Specifically, the wires processed by the automation equipment include two thin wires, and the two wires are respectively wrapped with an inner insulating layer and then wrapped with an outer insulating layer. In order to facilitate the second cutter mechanism 4 to cut the inner insulating layer of the wire 10, before the wire 10 is sent to the second cutter mechanism 4, it is necessary to ensure that the two thin wires in the wire are arranged horizontally, that is, the two thin wires are located in the same horizontal plane, and cannot be in a vertically stacked state, that is, they cannot be located in the same vertical plane, or other postures.

[0034] Figure 7It is a partial front view of the second cutter mechanism of the automation equipment according to one embodiment. The second cutter mechanism 4 is used to strip the outer insulation layer and the inner insulation layer of the second end 102 of the wire 10, and it further includes an outer cutter 41 for stripping the outer insulation layer and an inner cutter 42 for stripping the inner insulation layer, and the outer cutter 41 and the inner cutter 42 are arranged side by side along the direction of the wire. In a specific embodiment, the outer cutter 41 is farther away from the second end 102 of the wire 10 than the inner cutter 42. The outer cutter 41 is configured to control the closing distance of the outer cutter 41 so that when the outer cutter 41 cuts the outer insulation layer of the wire 10, the inner cutter 42 does not cut the inner insulation layer. The outer cutter 41 is provided with a U-shaped notch 411 to prevent the outer cutter 41 from damaging the inner insulation layer when cutting the outer insulation layer; and the inner cutter 42 is provided with a W-shaped notch 421 to prevent the inner cutter from damaging the metal wire when cutting the inner insulation layer. Figure 8 shown.

[0035] During operation, the second clamp 5 moves a predetermined distance along the direction of the wire toward the second cutter mechanism 4 to deliver the second end 102 of the wire 10 to the outer cutter 41. The outer cutter 41 and the inner cutter 42 are closed at the same time. At this time, only the outer cutter 41 cuts the outer insulation layer of the second end 102 of the wire 10, while the inner cutter 41 does not work. After the outer cutter 41 cuts off the outer insulation layer of the second end 102, the second cutter mechanism 4 moves away from the second clamp 5 in the closed state to strip the outer insulation layer of the second end 102. Figure 9a shown.

[0036] After stripping the outer insulation layer of the second end 102, the second cutter mechanism 4 opens and retracts to a predetermined position to prepare for stripping the inner insulation layer of the second end 102. The second cutter mechanism 4 closes again, and the outer cutter 41 does not work at this time, while the inner cutter 42 cuts the inner insulation layer of the second end 102 of the wire 10. After the inner cutter 42 cuts the inner insulation layer of the second end 102, the second cutter mechanism 4 moves away from the second clamp 5 again in the closed state to strip the inner insulation layer of the second end 102, as shown in FIG. Figure 9b In this way, the automation equipment strips off the inner and outer insulation layers of the second end 102 of the wire 10 .
