Description

Technical Field

[0001] The present invention relates to the technical field of automatic wire stripping and paralleling equipment, and in particular to an automatic wire stripping and paralleling integrated device and equipment. Background Art

[0002] In the construction of building electrical installation, there are many cases where two or three wires need to be connected in parallel in the wiring circuit design drawing. However, the 2.5, 4, and 6mm BV, BYJ, and BVV models suitable for traditional industrial or residential use are not suitable for the wiring circuit design drawing. 2 When joining wires, the insulation of each wire must first be stripped off using wire strippers or a utility knife. Then, the copper cores must be twisted and joined together using pliers or by hand. Manual stripping can easily cause the wires to break due to uneven force, and the wires can also become loose due to loose ends, wasting resources and posing a safety hazard. Furthermore, it's estimated that a skilled electrician takes an average of 20-30 seconds to strip and join three BV2.5 wires. As the number of joining points increases, manual efficiency decreases and the joining time increases.

[0003] Currently, there are only wire stripping tools on the market, such as large wire stripping machines or small wire stripping pliers, and there is no integrated device or equipment that automatically completes wire stripping and wiring.

[0004] Therefore, there is an urgent need for an integrated device or equipment that can automatically complete wire stripping and wire joining. Summary of the Invention

[0011] In one embodiment of the present invention, the axisymmetric line of the first wire stripping and paralleling hole is parallel to the axisymmetric line of the second wire stripping and paralleling hole.

[0012] In one embodiment of the present invention, the axial symmetry line of the first wire stripping and paralleling hole and the axial symmetry line of the second wire stripping and paralleling hole are respectively perpendicular to the line connecting the first center of the circle corresponding to the arc structure of the first wire stripping and paralleling hole and the second center of the circle corresponding to the arc structure of the second wire stripping and paralleling hole.

[0013] In one embodiment of the present invention, a third wire stripping and paralleling hole is further provided on the turntable; the third wire stripping and paralleling hole is provided in the middle position between the first wire stripping and paralleling hole and the second wire stripping and paralleling hole; wherein, the arc structure of the third wire stripping and paralleling hole faces the direction in which the pistol drill drives the turntable to rotate; an angle is formed between the axial symmetry line of the third wire stripping and paralleling hole and the axial symmetry line of the first wire stripping and paralleling hole or the axial symmetry line of the second wire stripping and paralleling hole.

[0014] In one embodiment of the present invention, the arc-shaped structure of the third wire stripping and paralleling hole corresponds to an eccentric position, and the inverted trapezoidal structure corresponds to an axial position; the axial position is the position where the axis of the wire is located when the wire is offset to the bottom of the inverted trapezoidal structure in the third wire stripping and paralleling hole due to the force of the rotation of the turntable.

[0023] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0024] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0025] It should be noted that the wires used in the automatic wire stripping and wiring device and equipment of the present invention include but are not limited to industrial and residential BV, BYJ, BVV and other types of 2.5mm 2 , 4mm 2 , 6mm 2 etc. hard copper wire.

[0026] like Figure 1 FIG2 is a schematic diagram showing the structure of an automatic wire stripping and wiring device in one embodiment of the present invention. As shown in the figure, the device comprises: a turntable 1 and a locking structure 2 at the bottom of the turntable 1.

[0027] Specifically, the turntable 1 is provided with a plurality of wire stripping and paralleling holes 3; the inner side of the wire stripping and paralleling holes 3 is provided with a sharp edge 31; the bottom of the turntable 1 is provided with a locking structure 2 for detachably fixing with a pistol drill bit; wherein, by starting the pistol drill bit to drive the turntable 1 to rotate, the wires 4 placed in each of the wire stripping and paralleling holes 3 are forced to be squeezed toward the sharp edge 31 for stripping, and the wires 4 are entangled with each other for paralleling.

[0028] In some embodiments, the engaging structure 2 of the present invention can be a screw or a shaft that can be directly inserted into the slot of the pistol drill bit. Alternatively, the pistol drill bit has an external thread structure, and the engaging structure 2 is a screw hole that can be connected and fixed with the external thread structure.

[0029] Simply put, two or three wires 4 to be stripped and paralleled are inserted into the stripping and paralleling holes 3 on the turntable 1. The turntable 1 is then clamped and fixed to the pistol drill bit. For safety, wire pliers 5 can be used to secure the wires 4. The pistol drill is then turned on, driving the turntable 1 to rotate. Because each stripping and paralleling hole 3 in this device is equipped with a sharp edge 31, the rotation of the turntable 1 causes each wire 4 to be squeezed in the opposite direction of the stripping and paralleling hole 3 under the action of eccentric force, that is, each wire 4 is squeezed toward the sharp edge 31. Therefore, this device can simultaneously strip multiple wires 4 while rotating and winding them to achieve paralleling.

[0030] like Figure 2 Figure 1 shows a cross-sectional schematic diagram of a stripping and paralleling hole 3 in one embodiment of the present invention. As shown, the inner circle represents the copper core 42, and the outer circle represents the insulating sheath 41. The upper portion of the stripping and paralleling hole 3 is an arc-shaped structure, while the lower portion is an inverted trapezoidal structure. The two ends of the arc connect to the tops of the two sides of the inverted trapezoidal structure.

[0031] Preferably, the diameter of the arc structure is greater than or equal to the outer diameter of the wire 4 to be inserted (i.e., the diameter of the insulating outer skin 41); the curvature of the arc structure is greater than π / 2 and less than π; the length of the bottom side of the inverted trapezoidal structure is equal to the diameter of the copper core 42 inserted into the wire 4.

[0032] Simply put, the curvature of the arc structure is smaller than that of the semicircular arc and larger than the curvature of one of the four branches. The diameter of the arc structure is greater than or equal to the preset outer diameter of the wire 4 to be inserted, that is, the setting of the size of the arc structure is determined according to the outer diameter of the wire 4 to be inserted, and the wire 4 of the corresponding size can be just inserted.

[0033] In one embodiment of the present invention, both sides of the inverted trapezoidal structure are provided with sharpened edges 31 ; and the bottom side of the inverted trapezoidal structure is provided with an unsharpened edge 32 .

[0034] In short, the sharpened edge 31 is a sharp edge with the same sharpness and thickness as a common utility knife, which is used for cutting and peeling; while the unsharpened edge 32 is a blunt edge with a thickness of about 2 mm, which is used for stretching and peeling.

[0035] Specifically, the space of the stripping and winding hole 3 in the present invention is preferably just enough to insert the wire 4 of the corresponding size. In the initial state or static state, the position of the inserted wire 4 is as follows: Figure 2 As shown, since the two sides of the inverted trapezoidal structure are wider at the top and narrower at the bottom, the wire 4 cannot move further downward without external force. However, when subjected to external force, i.e., when the pistol drill drives the turntable 1 to rotate, the wire 4 is squeezed downward by the eccentric force. Simultaneously, the sharp edges 31 on the two sides of the inverted trapezoidal structure cut the insulating sheath 41, ultimately squeezing the wire 4 to the bottom of the inverted trapezoidal structure. The length of the bottom is equal to the diameter of the copper core 42 inside the wire 4, thus preventing excessive cutting of the copper core 42.

[0036] It should be noted that, since the turntable 1 rotates, the wires 4 in the stripping and paralleling holes 3 also rotate to a certain extent relative to the stripping and paralleling holes 3. Therefore, the sharp edges 31 on both sides of the inverted trapezoidal structure can completely cut the insulation 41 of the wires 4. Even if there is an incomplete cut, since the sharp edges 31 have already cut into the insulation 41, the insulation 41 can be stripped when the wires 4 are subsequently pulled out of the stripping and paralleling holes 3 of the turntable 1.

[0037] Preferably, the size of the stripping and paralleling holes 3 on the turntable 1 of the present invention is pre-set and corresponds to only one size of wire 4. Different sizes of stripping and paralleling holes 3 can be set on different turntables 1. If wires 4 of other sizes need to be stripped and paralleled, the turntable 1 can be replaced.

[0038] It should be noted that two wire stripping and paralleling holes 3 can be provided on the turntable 1 of the present invention for stripping and paralleling two wires 4; in addition, three wire stripping and paralleling holes 3 can be provided on the turntable 1 of the present invention for stripping and paralleling three wires 4, or, by selecting any two adjacent wire stripping and paralleling holes 3, the stripping and paralleling of two wires 4 can also be achieved.

[0039] like Figure 3AFIG2 is a schematic cross-sectional view of a turntable 1 according to an embodiment of the present invention. The first stripping and doubling hole 3 and the second stripping and doubling hole 3 are centrally symmetrical about the center of the turntable 1. The arc-shaped structures of the first stripping and doubling hole 3A and the second stripping and doubling hole 3B are oriented in the direction in which the pistol drill drives the turntable 1.

[0040] It should be noted that, in order to further improve the wire stripping effect, the present invention also makes unique or special settings for the angles and positions of the wire stripping and paralleling holes 3 on the turntable 1 .

[0041] Specifically, the axisymmetric line of the first wire stripping and paralleling hole 3A is parallel to the axisymmetric line of the second wire stripping and paralleling hole 3B.

[0042] In one embodiment of the present invention, the axial symmetry line of the first wire stripping and paralleling hole 3A and the axial symmetry line of the second wire stripping and paralleling hole 3B are respectively perpendicular to the line connecting the first center of the circle corresponding to the arc structure of the first wire stripping and paralleling hole 3A and the second center of the circle corresponding to the arc structure of the second wire stripping and paralleling hole 3B.

[0043] Preferably, as shown in FIG3 , the first center of the circle and the second center of the circle are respectively the initial positions O1 after the wires 4 are inserted into the first stripping and paralleling hole 3A and the second stripping and paralleling hole 3B.

[0044] It should be noted that, in some embodiments, the axial symmetry line of the first stripping and paralleling hole 3A and the axial symmetry line of the second stripping and paralleling hole 3B can also be set to be non-perpendicular to the above-mentioned connection line, such as being deviated to the left or right at a certain angle to achieve the same stripping effect.

[0045] For example, if the dial 1 is pressed Figure 3A As shown in the clockwise rotation, it can be seen that the arc-shaped structure of the first stripping and paralleling hole 3A is facing or corresponding to the clockwise rotation direction, while the bottom edge of the inverted trapezoidal structure is facing away from the clockwise rotation direction. The same is true for the second stripping and paralleling hole 3B. In this way, after the clockwise rotation, the wires 4 inserted into the first stripping and paralleling hole 3A and the second stripping and paralleling hole 3B will be squeezed toward the bottom edge in the opposite direction of the clockwise rotation. During the squeezing process, the blades 31 on both sides will cut the insulation 41 of the wires 4, thereby achieving the stripping of the wires 4. Figure 3A The position of the shaded circle in the first stripping and paralleling hole 3A and the second stripping and paralleling hole 3B is the deviation position O2 where the wire 4 is squeezed to the bottom edge after the turntable 1 rotates.

[0046] It should be noted that when the turntable 1 is provided with two stripping and paralleling holes 3, the distance between the two is not limited to Figure 3A As shown in FIG, it is only a schematic distance. In some embodiments, the distance between the two stripping and paralleling holes 3 can be greater than Figure 3AThe distance indicated in the figure is closer, or even adjacent.

[0047] like Figure 3B The figure shows a cross-sectional schematic diagram of a turntable 1 according to another embodiment of the present invention. As shown, the turntable 1 is further provided with a third stripping and doubling hole 3C; the third stripping and doubling hole 3C is located midway between the first stripping and doubling hole 3A and the second stripping and doubling hole 3B. The arc-shaped structure of the third stripping and doubling hole 3C faces the direction of rotation of the turntable 1 driven by the pistol drill bit. An angle is formed between the axis of symmetry of the third stripping and doubling hole 3C and the axis of symmetry of the first stripping and doubling hole 3A or the axis of symmetry of the second stripping and doubling hole 3B. Preferably, the angle is greater than 30° and less than 60°.

[0048] In such Figure 3B In the embodiment, the arc-shaped structure of the third stripping and paralleling hole 3C faces the upper right. Of course, the arc-shaped structure of the third stripping and paralleling hole 3C may also face the lower left.

[0049] In one embodiment of the present invention, the arc-shaped structure of the third wire stripping and paralleling hole 3C corresponds to an eccentric position (i.e., the initial position O1 after the wire 4 is inserted), and the inverted trapezoidal structure corresponds to the axial position (i.e., the deviated position O2 of the wire after the turntable 1 rotates); the axial position is the position where the axial center of the wire 4 is located when the wire 4 is offset to the bottom of the inverted trapezoidal structure in the third wire stripping and paralleling hole 3C due to the force of the rotation of the turntable 1.

[0050] It should be emphasized that the initial position of the power supply line 4 inserted into the third stripping and paralleling hole 3C does not correspond to the center of the turntable 1, but corresponds to an eccentric position; the axis position corresponds to the center position of the turntable 1. This is also more conducive to wire stripping.

[0051] In the present invention, the center of the back of the turntable 1 is a cross-hollow design. After the wires 4 pass through the third wire stripping and paralleling hole 3C, the middle wire 4 can be offset and passed out.

[0052] This device takes the turntable 1 with three stripping and paralleling holes 3 as an example, and the specific operation embodiment can be described as follows:

[0053] First, fix the device on the pistol drill bit, and insert the three wires 4A, B, and C into the wire stripping and wiring holes 3 side by side. Use wire clamps 5 to clamp the wires 4 to the wire box and fix them. The wire clamps 5 are parallel to the wall and the ceiling.

[0054] Wire stripping principle:

[0055] 1) Start the pistol drill. When the turntable 1 starts to rotate clockwise, the wire 4A is subjected to the clockwise rotation force. Under the squeezing force of the sharp edges 31 on both sides, the insulation of the wire 4A is broken. The insulation of the wire 4C is broken in the same way.

[0056] 2) The upper part of the third stripping and paralleling hole 3 is at an eccentric position, and the lower part is at the axial position. In the initial state, the wire 4B is at an eccentric position. After being subjected to the rotational eccentric force, the wire 4B moves toward the axial position. Under the extrusion and cutting force of the blades 31 on both sides, the insulation on both sides of the wire 4B is broken.

[0057] 3) Because the bottom is an unsharpened blade 32 and the bottom length is equal to the diameter of the copper core 42, after the insulation is broken, when the copper core 42 reaches the bottom, the unsharpened blade 32 will not continue to cut and damage the copper core 42.

[0058] 4) After the turntable 1 starts to rotate rapidly, the insulation sheaths 41 of the three wires 4 have been broken. Then, the insulation sheaths 41 are pulled back quickly and evenly, and the copper cores 42 begin to be peeled off.

[0059] Parallel principle:

[0060] 1) When the insulation sheath 41 of the wire 4 is broken and then peeled off, the copper core 42 of the wire 4B remains unchanged at the axial position, and the copper cores 42 of the wires 4A and C on both sides rotate and wrap around the copper core 42 of the wire 4B under the rotational force of the blunt knife at the bottom.

[0061] 2) Pull the device evenly backward to simultaneously complete the stripping and paralleling of wires 4A, B, and C. The paralleling time is calculated to be about 8 to 10 seconds.

[0062] 3) To parallel two wires 4, insert them into the stripping and paralleling holes 3 on both sides and follow the above steps to complete the stripping and paralleling. The paralleling time is calculated to be approximately 6 to 8 seconds.

[0063] In one embodiment of the present invention, the automatic wire stripping and wiring integrated device of the present invention comprises: a pistol drill; Figure 1 The automatic wire stripping and wiring integrated device is detachably fixed to the drill bit of the pistol drill.

[0064] The present invention can automatically complete the wire sheath stripping and copper core paralleling of multiple wires at one time, greatly saving the wire stripping and paralleling construction time, and the automated mechanical construction saves manpower.

[0065] In summary, the present invention provides an automatic wire stripping and wiring integrated device and equipment, which can effectively overcome the various shortcomings of the existing technology and has high industrial utilization value.

[0066] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
