Description

Technical Field

[0001] The present invention belongs to the technical field of wire splicing, and in particular relates to a detection mechanism, a wire positioning device for wire processing equipment, and wire processing equipment. Background Art

[0002] When two bundles of wires are spliced, it is necessary to peel off a section of the insulation of each of the two bundles of wires to expose a portion of the exposed conductor. Each bundle of wires can be composed of one wire or multiple wires. The exposed conductors of the two bundles of wires are spliced by ultrasonic welding or the like, and then a section of insulating heat shrink tubing is wrapped around the exposed conductor. During processing, the insulating heat shrink tubing is heated so that the insulating heat shrink tubing is tightly wrapped with the insulation of the two bundles of wires or is bonded with the insulation, so that the original exposed conductor is wrapped inside. In the automated processing process, the two bundles of wires need to be fixed and the exposed conductor is in a specified position so that the insulating heat shrink tubing can cover the exposed conductor. Generally, the heat shrink tubing is aligned by a wire positioning device for a wire processing device, and the exposed conductor is located at a specified position by using a detection mechanism of the wire positioning device for the wire processing device, and then the heat shrink tubing is pushed to the specified position by a push mechanism of the wire positioning device for the wire processing device, so that the heat shrink tubing covers the exposed conductor.

The distance between the two conductive probes can be set to be not greater than the length of the exposed conductor part. If the exposed conductor part is located at the specified position, at least two conductive probes can be electrically connected to the exposed conductor part. At this time, the detection circuit forms a path through the exposed conductor part, thereby outputting an electrical signal. If the exposed conductor part is not at the specified position, less than two conductive probes are electrically connected to the exposed conductor part, so that a path cannot be formed between the two conductive probes, and an electrical signal cannot be output. Therefore, it can be determined whether the exposed conductor part is at the specified position by whether at least two conductive probes are electrically connected to the exposed conductor part. By driving the conductive component to move through the shifting component, the conductive component can be moved from the separation position to the contact position, and after the detection is completed, the conductive component can be moved from the contact position to the separation position, which can avoid the influence of the conductive probe on the next processing operation. The user can judge the position of the exposed conductor part by checking whether the two conductive components are conducting. If they are not conducting, the user can adjust the position of the wire so that the detection mechanism can detect again until the two conductive components are conducting, which means that the exposed conductor part is located at the specified position and the next processing can be carried out.

[0045] In order to make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0046] Please refer to Figure 1 and Figure 2 , the present invention provides a detection mechanism 100 for detecting the exposed conductor part on a wire 900. Among them, the exposed conductor part can conduct electricity, and other areas on the wire 900 except the exposed conductor part do not conduct electricity. Before detection, the wire 900 has been limited.

[0047] In this embodiment, the detection mechanism 100 includes a conductive component 110, a displacement component, a detection circuit, an adjustment component 120, and a slide rail.

[0048] Please refer to Figure 1 and Figure 2 , the conductive component 110 includes at least two conductive probes 111. The conductive probes 111 are used to contact the exposed conductor part, and the conductive probes 111 can conduct electricity. The two conductive probes 111 are spaced apart. In this embodiment, there are two conductive probes 111, and the distance between the two conductive probes 111 can be equal to the length of the exposed conductor part. The conductive probe 111 can be electrically connected to the exposed conductor part by contacting the exposed conductor part. When both conductive probes 111 are electrically connected to the exposed conductor part, the two conductive probes 111 can be connected through the exposed conductor part. In this embodiment, the detection circuit is electrically connected to the conductive probe 111, and the two conductive probes 111 output an electrical signal through the conduction of the detection circuit. Among them, the conductive probe 111 is sheet-shaped and its extending direction is perpendicular to the extending direction of the wire 900. In other embodiments, the conductive component 110 may also be provided with more than two.

[0049] The shifting component can drive the conductive component 110 to switch between a separated position and a contact position. When the shifting component drives the conductive component 110 to switch between the separated position and the contact position, the movement path can be a straight line, a broken line or a curve. Specifically, the conductive component 110 is slidably connected to the guide rail 141 of the fixing frame 140. The fixing frame 140 is used to be connected to an external structure, such as being connected to the bracket 500. The guide rail 141 extends along a straight line, that is, the movement path of the conductive component 110 is a straight line. The shifting component can drive the conductive component 110 to slide along the guide rail 141, so as to realize the switching of the conductive component 110 between the separated position and the contact position. In this embodiment, the conductive part can be slidably connected to the guide rail 141 through other components. Among them, the shifting component can be independently arranged with the conductive component 110. In this embodiment, the shifting component is connected to the conductive component 110, specifically connected to the probe base 112.

[0050] In this embodiment, the movement track of the conductive component 110 between the separated position and the contact position is a straight line. That is to say, the shifting component drives the conductive component 110 to reciprocate between the separated position and the contact position along a straight line. When the conductive component 110 is in the contact position, the conductive probe 111 contacts the wire 900. At this time, if the conductive probe 111 contacts the exposed conductor part, the conductive probe 111 is electrically connected to the exposed conductor part. If the conductive probe 111 contacts other positions on the wire 900 except the exposed conductor part, the conductive probe 111 is not electrically connected to the exposed conductor part. When the conductive component 110 is in the separated position, the conductive probe 111 is separated from the wire 900. At this time, each conductive probe 111 is not electrically connected to the exposed conductor part. Preferably, the movement track line of the conductive component 110 is perpendicular to the extension line of the wire 900 to realize the quick contact and separation between the conductive component 110 and the wire 900. Among them, the shifting component includes a shifting driving member 130. The shifting driving member 130 can drive the conductive component 110 and the adjusting component 120 to move along a straight line and make the conductive component 110 switch between the separated position and the contact position. The shifting driving member 130 can be a cylinder. The adjusting component 120 is connected to the piston rod of the cylinder. The piston of the cylinder can push the piston rod to move along a straight line, so that the adjusting component 120 drives the conductive component 110 to move along a straight line, and the conductive component 110 can switch between the separated position and the contact position.

[0051] Among them, when the conductive component 110 is in the contact position, the detection circuit detects and determines whether the bare conductor part on the wire 900 is in the specified position. When at least two conductive probes 111 are electrically connected to the bare conductor part on the wire 900, it is determined that the bare conductor part is in the specified position; when less than two conductive probes 111 are electrically connected to the bare conductor part on the wire 900, it is determined that the bare conductor part is not in the specified position. Specifically, when at least two conductive probes 111 are in contact with the conductor under test, the detection circuit is turned on, and it is determined that the bare conductor part is in the specified position. When less than two conductive probes 111 are in contact with the conductor under test, the detection circuit is turned off, and it is determined that the bare conductor part is not in the specified position.

[0052] That is to say, when the conductive component 110 is in the contact position, at least two conductive probes 111 are in contact with the wire 900. If the bare conductor part is located at the specified position, the at least two conductive probes 111 can be electrically connected to the bare conductor part. At this time, the at least two conductive probes 111 form a path through the bare conductor part, and the detection circuit is turned on, thereby outputting an electrical signal. If the bare conductor part is not in the specified position, less than two conductive probes 111 are electrically connected to the bare conductor part, so that the two conductive probes 111 cannot form a path, the detection circuit is turned off, and no electrical signal can be output. Therefore, it can be determined whether the bare conductor part is in the specified position by whether at least two conductive probes 111 are electrically connected to the bare conductor part. When the detection mechanism 100 performs an inspection, first, the shift component drives the conductive component 110 to move from the separation position to the contact position, the detection circuit performs detection, and after the detection is completed, the shift component drives the conductive component 110 to move from the contact position to the separation position. The user can judge the position of the bare conductor part by checking whether the detection circuit is turned on. If it is not turned on, the user can adjust the position of the wire 900 so that the detection mechanism 100 can detect again until the detection circuit is turned on, which means that the bare conductor part is located at the specified position and the next processing can be carried out.

[0053] Among them, whether the detection circuit is turned on can be prompted by light or sound devices. For example, a lamp or a sound alarm is set in the detection circuit. If the detection circuit is turned on, the lamp emits light or the sound alarm makes a sound to prompt the operator that the detection circuit is turned on. In addition, the electrical signal after the detection circuit is turned on can be used as a condition for the next processing. When the detection circuit is turned on, an electrical signal is output, and the upper computer controls the next processing equipment to continue working according to the electrical signal; if the detection circuit is not turned on, no electrical signal is output, and the upper computer controls the next processing equipment not to work.

[0054] The user can adjust the position of the wire 900 to adjust the bare conductor part to a position where at least two conductive probes 111 can be electrically connected. At this time, it can be determined that the bare conductor part is located at the specified position. In this way, the user can determine the position of the wire 900 through the detection mechanism 100.

[0055] The testing institution 100 drives the conductive component 110 to move through the shifting component, and can move the conductive component 110 from the separated position to the contact position, and move the conductive component 110 from the contact position to the separated position after the detection is completed, which can prevent the conductive probe 111 from affecting the next processing operation.

[0056] In this embodiment, the conductive probe 111 elastically abuts against the wire 900 when the conductive component 110 is in the contact position. In this way, the conductive probe 111 can always be in close contact with the wire 900, preventing the problem that the conductive probe 111 may be detached from the wire 900 after long-term use and avoiding poor contact.

[0057] Please refer to Figure 1 and Figure 2 As shown in, the conductive component 110 further includes a probe base 112. The conductive probe 111 is rotatably connected to the probe base 112. The shifting component can drive the probe base 112 to move so that the conductive probe 111 moves towards or away from the wire 900. The probe base 112 plays a supporting role for the conductive probe 111. Among them, two conductive probes 111 can be connected to one probe base 112. At this time, the distance between the two probe bases 112 is not adjustable. In this embodiment, there are two conductive probes 111, and each conductive probe 111 is respectively connected to a probe base 112. The two probe bases 112 can drive a conductive probe 111 to move respectively to adjust the distance between the two conductive probes 111.

[0058] Among them, the conductive probe 111 can be fixedly connected to the probe base 112. The conductive probe 111 itself can be elastic, or the probe base 112 is elastic. In this way, when the conductive component 110 is in the contact position, the conductive probe 111 or the probe base 112 undergoes elastic deformation, and the conductive probe 111 can apply an elastic force to the wire 900. At this time, the conductive probe 111 or the probe base 112 can be a metal spring piece.

[0059] Please refer to Figure 1 and Figure 2, in this embodiment, the conductive probe 111 is rotatably connected to the probe base 112. The extending direction of the probe base 112 is perpendicular to the extending direction of the wire 900. The rotation axis of the conductive probe 111 is parallel to the extending direction of the wire 900. The conductive assembly 110 further includes a first elastic member 113 connected to the conductive probe 111. The first elastic member 113 can elastically deform when the conductive assembly 110 is in the contact position and provide an elastic force for resetting the conductive probe 111. The middle part of the conductive probe 111 is rotatably connected to the probe base 112. One end of the conductive probe 111 is used to contact the wire 900 and the other end is connected to the first elastic member 113. One end of the first elastic member 113 is connected to the conductive probe 111 and the other end is connected to the probe base 112. When the conductive assembly 110 is in the contact position, the first elastic member 113 undergoes tensile deformation. When the conductive assembly 110 leaves the contact position, the conductive probe 111 resets under the elastic force of the first elastic member 113. Wherein, the first elastic member 113 can be a spring.

[0060] Under normal circumstances, when the heat shrinkable sleeve 910 is in the preset position, the midpoint of the bare conductor part coincides with the midpoint of the heat shrinkable sleeve 910. However, when the wires 900 on both sides of the bare conductor part are different in thickness or number of strands, if the midpoint of the bare conductor part still coincides with the midpoint of the heat shrinkable sleeve 910 when it is in the preset position, it may cause the heat shrinkable sleeve 910 to shrink towards one side after heat shrinkage, and ultimately result in the heat shrinkable sleeve 910 not being able to completely cover. Therefore, it is necessary to offset the preset position to a specified position, that is, to make the bare conductor part deviate from the original specified position, so as to achieve the coverage of the bare conductor part by the heat shrinkable sleeve 910 after heat shrinkage. For this reason, the detection mechanism 100 further includes an adjustment component 120. The adjustment component 120 can adjust the position of the conductive assembly 110 in the extending direction of the wire 900. Wherein, the above positions include the distance between two adjacent conductive assemblies 110, and also include the overall position of the conductive assembly 110. The displacement component can drive the conductive assembly 110 to move between the separation position and the contact position by driving the adjustment component 120 to move. In this way, the overall relative position of the conductive assembly 110 is maintained during displacement.

[0061] Please refer to Figure 1 and Figure 2, specifically, the adjusting component 120 further includes a first mounting seat 123, at least one first guide rod 121 and at least one slider 122. The first guide rod 121 is rotatably arranged, and the slider 122 is movably connected to the first guide rod 121 and can move along the extending direction of the first guide rod 121. The first mounting seat 123 is slidably connected to the guide rail 141. Among them, the first mounting seat 123 can be directly slidably connected to the guide rail 141. In this embodiment, the first mounting seat 123 is slidably connected to the guide rail 141 through other structures. The above-mentioned movable connection includes sliding connection, movable sleeving, screw connection, etc. In this embodiment, the slider 122 is screwed to the first guide rod 121. The extending direction of the guide rod is the same as the extending direction of the wire 900, and a conductive component 110 is connected to a slider 122. When the first guide rod 121 rotates, the slider 122 does not rotate. In this way, the first guide rod 121 realizes the reciprocating movement of the slider 122 along the extending direction of the first guide rod 121 through forward or reverse rotation. That is to say, when the slider 122 moves along the first guide rod 121, the conductive probe 111 moves along the extending direction of the wire 900. When the two sliders 122 move relatively or away from each other, the distance between the two conductive probes 111 is adjusted. When the two sliders 122 move in the same direction at the same time, the two conductive probes 111 maintain the current distance and move as a whole. Among them, for the convenience of the user to operate, a hand-held knob is provided at one end of the first guide rod 121.

[0062] Please refer to Figure 1 , in one embodiment, there is one first guide rod 121 and two sliders 122. The first guide rod 121 has a first thread section and a second thread section, and the thread directions of the first thread section and the second thread section are opposite. The two sliders 122 are respectively screwed to the first thread section and the second thread section. In this way, when the first guide rod 121 rotates, since the sliders 122 do not rotate, the slider 122 screwed to the first thread section and the slider 122 screwed to the second thread section are linked, and the moving directions are opposite. For example, when the first guide rod 121 rotates forward, the two sliders 122 move towards each other at the same time. When rotating in the reverse direction, the two sliders 122 move away from each other at the same time, thereby realizing the rapid adjustment of the distance between the two sliders 122, that is, the rapid adjustment of the distance between the two conductive probes 111. At the same time, the midpoint of the two conductive probes 111 remains unchanged, that is, the specified position remains unchanged. The user can adjust the distance between the two sliders 122 by screwing the first guide rod 121, so as to adapt to the length of the exposed conductor part. In this embodiment, the displacement component drives the first mounting seat 123 to move, thereby driving the conductive component 110 to switch between the separation position and the contact position.

[0063] To facilitate viewing the moving distance of the conductive probe 111 or the distance between the two conductive probes 111, the detection mechanism 100 further includes a first scale 150 connected to the first mounting base 123. The first scale 150 is used to indicate the position of the conductive probe 111. The extending direction of the first scale 150 is the same as that of the guide rod. During the movement of the conductive assembly 110, it can correspond to the scale on the first scale 150. The difference between the scales pointed to by the two conductive assemblies 110 is the distance between the two conductive assemblies 110.

[0064] Please refer to Figure 1 , when the conductive assembly 110 needs to be offset, to quickly achieve the overall offset of the conductive assembly 110, the adjusting assembly 120 further includes a second guide rod 124, a first mounting base 123 and a second mounting base 125. The first mounting base 123 is movably connected to the second guide rod 124. The second mounting base 125 is directly slidably connected to the guide rail 141. The first mounting base 123 is slidably connected to the guide rail 141 through the second mounting base 125. The second guide rod 124 is connected to the second mounting base 125. The first mounting base 123 can move along the extending direction of the second guide rod 124. The shifting assembly can drive the second mounting base 125 to slide along the extending direction of the guide rail 141, approaching or moving away from the wire 900, so that the conductive assembly 110 can be switched between the separated position and the contact position. Among them, the above-mentioned movable connection can be a sliding connection, a movable socket connection or a screw connection, etc. In this embodiment, the second guide rod 124 is screwed to the first mounting base 123. The second guide rod 124 can drive the first mounting base 123 to move along the extending direction of the second guide rod 124 by rotating around the axis. When the second guide rod 124 rotates, the first mounting base 123 does not rotate. The second guide rod 124 makes the first mounting base 123 reciprocate along the extending direction of the second mounting base 125 by rotating forward or backward. In use, the user can first adjust the distance between the two sliders 122 by screwing the first guide rod 121, and then adjust the position of the first mounting base 123 by screwing the second guide rod 124, so that the two conductive probes 111 can be offset as a whole while keeping the distance between the two conductive probes 111 unchanged.

[0065] Please refer to Figure 1 , to facilitate viewing the offset distance of the first mounting base 123, the offset detection mechanism 100 further includes a second scale 160 connected to the second mounting base 125. The second scale 160 is used to indicate the position of the first mounting base 123. The extending direction of the second scale 160 is the same as that of the guide rod. During the movement of the first mounting base 123, it can correspond to the scale on the second scale 160. The user can obtain the overall offset amount of the conductive probe 111 by reading the difference between the scale corresponding to the first mounting base 123 after adjustment and the scale corresponding to it before adjustment.

[0066] Please refer to Figure 2 In another embodiment, there are two first guide rods 121. The two first guide rods 121 are located on the same straight line, and a slider 122 is screwed onto one of the first guide rods 121. In this way, the two first guide rods 121 drive a slider 122 to move respectively, that is, the positions of the two sliders 122 are adjusted respectively. It can not only adjust the distance between the two sliders 122, but also realize the offset of the two sliders 122, that is, the midpoint position between the two sliders 122 changes. That is to say, the midpoint position between the two conductive probes 111 changes, and the specified position changes immediately to complete the offset of the conductive component 110. The adjusting component 120 in this embodiment can synchronously adjust the distance between the two conductive components 110 and the overall position of the conductive component 110, and the second mounting seat 125 and the second guide rod 124 may not be provided.

[0067] However, when offsetting the conductive component 110, the operation of adjusting the two first guide rods 121 respectively is rather cumbersome. The user needs to screw the two first guide rods 121 respectively to make the conductive component 110 move the same distance. Therefore, in order to realize the quick offset of the conductive component 110, the second guide rod 124 and the second mounting seat 125 may also be provided. The first mounting seat 123 is movably connected to the second guide rod 124, the second mounting seat 125 is directly slidably connected to the guide rail 141, the first mounting seat 123 is slidably connected to the guide rail 141 through the second mounting seat 125, the second guide rod 124 is connected to the second mounting seat 125, and the first mounting seat 123 can move along the extension direction of the second guide rod 124. The displacement component can drive the second mounting seat 125 to slide along the extension direction of the guide rail 141 to make the conductive component 110 switch between the separation position and the contact position. Among them, the above-mentioned movable connection can be a sliding connection, a movable socket connection or a screw connection, etc. In this embodiment, the second guide rod 124 is screwed to the first mounting seat 123, and the second guide rod 124 can drive the first mounting seat 123 to move along the extension direction of the second guide rod 124 by rotating around the axis. When the second guide rod 124 rotates, the first mounting seat 123 does not rotate. The second guide rod 124 makes the first mounting seat 123 reciprocate along the extension direction of the second mounting seat 125 by forward rotation or reverse rotation. In use, the user can first adjust the distance between the two sliders 122 by screwing the first guide rod 121, and then adjust the position of the first mounting seat 123 by screwing the second guide rod 124. In this way, the overall offset of the two conductive probes 111 can be achieved while keeping the distance between the two conductive probes 111 unchanged.

[0068] Please refer to Figure 2, in the above embodiments, a first scale 150 is provided on the first mounting base 123. The first scale 150 is used to indicate the position of the conductive probe 111. The extending direction of the first scale 150 is the same as that of the guide rod. During the movement of the conductive assembly 110, it can always correspond to the scale on the first scale 150. The difference between the scales pointed to by the two conductive assemblies 110 is the distance between the two conductive assemblies 110, and half of the sum of the scales pointed to by the two conductive assemblies 110 is the midpoint position of the two conductive assemblies 110. Thus, the offset distance of the current preset position compared to the original preset position can be obtained. At the same time, a second scale 160 can also be provided on the second mounting base 125. The second scale 160 is used to indicate the position of the first mounting base 123. The extending direction of the second scale 160 is the same as that of the guide rod. During the movement of the first mounting base 123, it can always correspond to the scale on the second scale 160. By reading the difference between the scale corresponding to the first mounting base 123 after adjustment and the scale corresponding to it before adjustment, the user can obtain the overall offset amount of the conductive probe 111.

The limiting mechanism 200 is slidably connected to the bracket 500, and the wire feeding mechanism 400 is connected to the limiting mechanism 200.

[0071] Please refer to Figure 4 and Figure 5 , the limiting mechanism 200 can limit the displacement of the wire 900 during the process of detecting the bare conductor part on the wire 900 and pushing and dialing the heat shrinkable sleeve 910. In this embodiment, the limiting mechanism 200 is a clamping jaw 210, which can limit the displacement of the wire 900 by clamping. The limiting mechanism 200 can include a moving frame 220 and two clamping jaws 210 connected to the moving frame 220 to fix the position of the wire 900. After the wire 900 is fixed, it is in a tensioned state, and the bare conductor part is located between the two clamping jaws 210.

[0072] The push mechanism 300 is used to push the heat shrink sleeve 910 sleeved on the wire 900 to a preset position. The heat shrink sleeve 910 can be a heat shrink sleeve 910, the inner diameter of the heat shrink sleeve 910 is larger than the outer diameter of the wire 900, and can slide on the wire 900, and the length of the heat shrink sleeve 910 is not less than the length of the exposed conductor. The preset position can be a designated position, or it can deviate from the designated position. The heat shrink sleeve 910 at the preset position can cover the exposed conductor at the designated position after heat shrinkage. The push mechanism 300 can contact the wire 900 when the limiting mechanism 200 clamps the wire 900.

[0073] See also Figure 4 and Figure 5 The push mechanism 300 includes a driving member 310 and a push assembly 320.

When the two push-pull assemblies 320 move toward each other, they can finally move the heat shrinkable sleeve 910 to a preset position by clamping the heat shrinkable sleeve 910. When the two push-pull assemblies 320 both contact the heat shrinkable sleeve 910, the distance between the two is equal to or slightly less than the length of the heat shrinkable sleeve 910; when the two push-pull assemblies 320 move away from each other, the push-pull assemblies 320 are separated from the heat shrinkable sleeve 910. The driving member 310 includes a driving motor 311, a gear 312 connected to the driving motor 311, and two racks 313 meshed with the gear 312. One push-pull assembly 320 is connected to one rack 313, and the two racks 313 are arranged in opposite directions and in parallel. When the driving motor 311 drives the gear 312 to rotate, the two racks 313 move synchronously in opposite directions, thereby realizing the linkage of the two push-pull assemblies 320.

[0076] See also Figure 7The push-pull assembly 320 includes a connecting member 322, a resisting member 321, a second elastic member 323 and a sensor. The connecting member 322 can move toward or away from the preset position when driven by the driving member 310. The second elastic member 323 is connected to the resisting member 321. Specifically, the second elastic member 323 is located between the resisting member 321 and the connecting member 322. The driving member 310 can drive the connecting member 322 to move toward or away from the preset position. The resisting member 321 is slidably connected to the connecting member 322 and is located on the side of the connecting member 322 facing the preset position.

When both push and pull assemblies 320 abut against the heat shrinkable tube 910, the two abutting members 321 abut against the heat shrinkable tube 910, and each abutting member 321 is subjected to the pressure of another abutting member 321, and the second elastic member 323 is compressed, so that the second elastic member 323 acts as a buffer for the movement of the heat shrinkable tube 910, preventing the push and pull mechanism 300 from clamping and deforming the heat shrinkable tube 910. The abutting member 321 elastically abuts against the wire 900 to ensure that the abutting member 321 can be moved to the heat shrinkable tube 910. The resisting member 321 may include a resisting hand 3211, a resisting seat 3212 and a third elastic member 3213. The resisting seat 3212 is slidably connected to the connecting member 322, the resisting hand 3211 is rotatably connected to the resisting seat 3212, and the third elastic member 3213 is connected to the resisting hand 3211 and the resisting seat 3212. When the resisting member 321 resists the wire 900, the resisting hand 3211 resists the wire 900, and the third elastic member 3213 is elastically deformed and applies a resetting elastic force to the resisting hand 3211. The sensor is connected to the connecting member 322. The resisting member 321 can touch the sensor when it resists the heat shrinkable sleeve 910 and the second elastic member 323 is compressed to a certain distance.

In this embodiment, the contact seat 3212 is provided with a contact rod extending toward the sensor. When the contact rod touches the sensor, the sensor sends a control signal.

[0077] See also Figure 5, the wire feeding mechanism 400 can move the limiting mechanism 200 relative to the bracket 500, and transfer the wire 900 to the predetermined processing position. Specifically, the wire feeding mechanism 400 is connected to the moving frame 220, and can drive the moving frame 220 to move so that the limiting mechanism 200 moves toward the heat shrinking machine. The limiting mechanism 200 releases the wire 900 when the wire 900 is located above the crawler, so as to place the wire 900 on the crawler, and the predetermined processing position is located on the crawler, that is, the wire feeding mechanism 400 can drive the limiting mechanism 200 to move so that the wire 900 is placed on the crawler, and the crawler can transport the wire 900 into the heating device of the heat shrinking machine for heat shrinking. A movable track is provided on the bracket 500, the limiting mechanism 200 is slidably connected to the movable track, the wire feeding mechanism 400 includes a wire feeding motor 410 and a synchronous belt 420 connected to the wire feeding motor 410, the movable frame 220 is connected to the synchronous belt 420, and the wire feeding motor 410 can drive the synchronous belt 420 to move, thereby driving the movable frame 220 to move.

[0079] When in use, the user first places the wire 900 on the two clamping jaws 210, and the two clamping jaws 210 clamp the wire 900. At this time, the contact member 321 elastically contacts the wire 900, and the detection mechanism 100 detects the position of the exposed conductor part. When it is detected that the exposed conductor part is in the specified position, the driving member 310 drives the two push wave components to move toward each other until the two contact hands 3211 both contact the heat shrink sleeve 910. When the contact member 321 touches the sensor, the driving member 310 stops driving. At this time, the heat shrink sleeve 910 is in a preset position. Then the driving member 310 drives the push and pull components 320 to move back to the initial position. At this time, the wire feeding motor 410 drives the synchronous belt 420 to move, and the synchronous belt 420 drives the moving frame 220 to move until the wire 900 is fed into the heat shrink machine, the clamping jaws 210 are separated from the wire 900, and the wire feeding motor 410 drives the synchronous belt 420 to move in the opposite direction until the moving frame 220 is reset for the next round of operation.
