Description

Technical Field

[0001] The invention relates to the technical field of clamps, and in particular to a clamping mechanism for removing a wire coating layer by laser. Background Art

[0002] Wires are commonly used components in electronic devices. When processing wires, after removing the outer sheath of the wires, the inner strands are exposed. The sheath of the strands at the head of the wires needs to be stripped and cut. The traditional method is to manually strip with wire strippers. Inaccurate manual stripping positions can easily lead to scrapping and low efficiency.

[0003] In order to solve the above problems, especially for multi-strand wires, laser is currently used to strip the wire head wrapping layer. Laser cutting is a non-contact process. During processing, the wire will not deform or warp, and there will be no tool wear problems. However, laser processing must place the wire at the laser focus position, so a special clamp is needed to press the head and tail of the wire so that the wire is laid flat on the clamp. After the laser stripping is completed, the waste part of the wire head also needs to be cut to keep the stripping size accurate, which cannot be achieved with existing clamps. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a clamping mechanism for laser removal of wire wrapping layers, which can accurately position the wire, accurately complete laser cutting, and can cut off multiple strands of wire waste at the head of the wire, ensure the consistency of the size of the wire ends, and improve production efficiency and quality.

[0005] In order to solve the above technical problems, the present invention provides a clamping mechanism for laser removal of wire sheathing layer, including a base plate, the surface of the base plate is provided with a wire slot group, a first multi-strand wire slot group and a second multi-strand wire slot group in sequence along the axial direction of the wire, a cutting groove is provided between the first multi-strand wire slot group and the second multi-strand wire slot group, the top of the base plate is provided with a first pressing plate mechanism, a second pressing plate mechanism and a third pressing plate mechanism in sequence along the axial direction of the wire, the first pressing plate mechanism is used to press the end of the wire into the wire slot group, the second pressing plate mechanism is used to press the tail of each multi-strand wire into the first multi-strand wire slot group, the third pressing plate mechanism is used to press the head of each multi-strand wire into the second multi-strand wire slot group, and a tool assembly is provided on the inner side of the third pressing plate mechanism, the tool assembly is used to cut off the head of the multi-strand wire along the cutting groove after laser cutting the sheathing layer of the multi-strand wire.

[0006] In the above-mentioned clamping mechanism, the main body of the wire, the tail of the multi-strand wire and the head of the multi-strand wire are respectively pressed and fixed in the corresponding slots by the first pressing plate mechanism, the second pressing plate mechanism and the third pressing plate mechanism, so that the wire is clamped flatly and firmly on the bottom plate, so that the part of the multi-strand wire to be laser cut is accurately positioned at the laser focus position, thereby improving the efficiency and quality of laser peeling and providing sufficient fixing force for cutting off the heads of the multi-strand wires; in addition, after the laser cutting is completed, the heads of the multi-strand wires are cut off by the tool assembly, so that the size of the wire laser cutting and stripping of the wrapping layer is accurate and consistent.

[0007] As an improvement of the clamping mechanism of the present invention, the third pressure plate mechanism includes a third pressure plate, both ends of the third pressure plate are hinged with rockers, the two rockers are respectively hinged on the bottom plate on both sides of the second multi-strand wire slot group, and form a parallelogram linkage mechanism with the third pressure plate, the bottom of the third pressure plate is provided with a pressure block and the tool assembly side by side in its width direction, the pressure block is arranged on the top of the second multi-strand wire slot group and is magnetically attracted to the second multi-strand wire slot group, guide slide rods are fixed to the top surfaces of both ends of the pressure block, the guide slide rods slide through the third pressure plate, and limited position ends are provided at the ends, the guide slide rod is located between the third pressure plate and the pressure block and is provided with a spring on the outside of the rod body, and the tool assembly is fixedly connected to the third pressure plate.

[0008] In the third pressure plate mechanism, the third pressure plate and the rocker form a parallelogram linkage mechanism to achieve the vertical translation of the third pressure plate, driving the pressure block and the tool assembly to move up and down. The pressure block is elastically supported and connected by the spring and the guide slide bar. After the third pressure plate moves downward, the pressure block presses the heads of the multi-strand wires and laser cuts the wrapping layer. The third pressure plate continues to move downward to only drive the tool assembly to cut the heads of the multi-strand wires and remove the waste from the heads of the multi-strand wires, so that the length of the remaining multi-strand wires after stripping the wrapping layer is consistent. The entire structural design is ingenious and compact. The third pressure plate is moved downward twice to complete the actions of pressing and cutting the heads of the multi-strand wires. It is easy to operate and has complete functions. Cutting the wrapping layer and removing the waste from the wire heads can be achieved on the same fixture.

[0009] In summary, the clamping mechanism is reasonably designed and compact in structure. The clamped wire is accurately and firmly positioned, and can achieve precise laser cutting of the wrapping layer and remove waste at the wire head to ensure accurate peeling size. It also avoids the waste of production cost and time caused by a single-function fixture, greatly improving the efficiency and quality of laser peeling. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0020] like Figure 1As shown, a clamping mechanism for laser removal of a wire sheathing layer of the present invention comprises a base plate 1, a wire slot group 21, a first multi-strand wire slot group 22 and a second multi-strand wire slot group 23 are sequentially arranged on the surface of the base plate 1 along the axial direction of the wire, a cutting groove 3 is arranged between the first multi-strand wire slot group 22 and the second multi-strand wire slot group 23, a first pressing plate mechanism 4, a second pressing plate mechanism 5 and a third pressing plate mechanism 6 are sequentially arranged at intervals along the axial direction of the wire on the top of the base plate 1, the first pressing plate mechanism 4 is used to press the end of the wire into the wire slot group 21, the second pressing plate mechanism 5 is used to press the tail of each multi-strand wire into the first multi-strand wire slot group 22, the third pressing plate mechanism 6 is used to press the head of each multi-strand wire into the second multi-strand wire slot group 23, and a tool assembly 7 is arranged on the inner side of the third pressing plate mechanism 6 (the side close to the second pressing plate mechanism 5), and the tool assembly 7 is used to cut off the head of the multi-strand wire along the cutting groove 3 after laser cutting the sheathing layer of the multi-strand wire.

[0021] like Figure 2 and Figure 3 As shown, the third pressure plate mechanism 6 includes a third pressure plate 61, both ends of the third pressure plate 61 are hinged with rockers 62, the two rockers 62 are respectively hinged on the bottom plate 1 on both sides of the second multi-strand wire slot group 23, and form a parallelogram linkage mechanism with the third pressure plate 61, the bottom of the third pressure plate 61 is provided with a pressure block 63 and a tool assembly 7 side by side in its width direction, the pressure block 63 is arranged at the top of the second multi-strand wire slot group 23, and is magnetically attracted to the second multi-strand wire slot group 23, the top surfaces of both ends of the pressure block 63 are fixed with guide slides 64, the guide slides 64 slide through the third pressure plate 61, and the end is provided with a limited end, the guide slide 64 is located between the third pressure plate 61 and the pressure block 63 The rod body outside is provided with a spring 65, and the tool assembly 7 is fixedly connected to the third pressure plate 61. The third pressing plate mechanism 6 can not only press the multi-strand wires in the second multi-strand wire clamping slot group 23, but also integrate the tool assembly 7 into its own pressing structure, so that the structure of the entire clamp is compact and easy to operate.

[0022] When in use, open the first pressing plate mechanism 4 and the second pressing plate mechanism 5, and move the third pressing plate 61 upwards, take out the wires with the ends of the wires removed to expose the multi-strand wires, place the body of each wire in the wire slot group 21, and place the multi-strand wires in the first multi-strand wire slot group 22 and the second multi-strand wire slot group 23; then use the first pressing plate mechanism 4 and the second pressing plate mechanism 5 to press the body of the wire and the tail of the multi-strand wire respectively, and use the parallelogram linkage mechanism to translate the third pressing plate 61 downwards until the pressing block 63 is magnetically attracted to the second multi-strand wire slot group 23 on the bottom plate 1, and the heads of the multi-strand wires are pressed, so that the wires are accurately and firmly fixed in a three-point manner as a whole; then use the laser to The clearance between the second pressure plate mechanism 5 and the tool assembly 7 is set to the position to cut the wrapping layer of the multi-strand head. Usually, the laser cutting position is 2 to 5 mm away from the position where the tool assembly 7 cuts off or the cutting groove 3. Then, after the laser cutting is completed, the third pressure plate 61 is continuously translated downward. As the guide slide bar 64 slides upward, the spring 65 is compressed, and the pressure block 63 keeps the multi-strand wire head pressed and immobilized, while the tool assembly 7 continues to move downward into the cutting groove 3 to achieve the cutting of the multi-strand wire. Finally, the wire is removed from the clamping mechanism, the waste in the clamping mechanism is cleaned, and the processing is completed to obtain the wire with the same stripping size of the end multi-strand wire. When the wire is used, the wrapping layer of the multi-strand wire is manually removed. The entire third pressure plate mechanism 6 integrates the functions of clamping and cutting, with a clever structural design and strong practicality.

[0023] In order to make the length of the wrapping layer consistent after laser cutting of the multiple strands of wire, the cutting groove 3 is arranged in a direction perpendicular to the first multiple strands of wire slot group 22 or the second multiple strands of wire slot group 23, and the depth of the groove bottom is lower than the first multiple strands of wire slot group 22 or the second multiple strands of wire slot group 23.

[0024] Optionally, the clamping mechanism on the bottom plate 1 is symmetrically arranged in two groups. That is, the clamping mechanism on the bottom plate 1 is a bilaterally symmetrical structure, and there are two wire slot groups 21, first multi-strand wire slot groups 22, second multi-strand wire slot groups 23, first pressure plate mechanisms 4, second pressure plate mechanisms 5 and third pressure plate mechanisms 6, and each is symmetrically arranged on the surface of the bottom plate 1. Two groups are symmetrically arranged on the bottom plate 1 to increase the number of wires clamped at a time and improve efficiency, and the entire clamping mechanism structure is arranged symmetrically and reasonably.

[0025] like Figure 4As shown, the bottom ends of the two rocking arms 62 are hinged with a third shaft seat 66 and a fourth shaft seat 67 respectively, and the third shaft seat 66 and the fourth shaft seat 67 both include a convex-shaped supporting body, the supporting body of the third shaft seat 66 is arranged along the length direction of the third pressure plate 61, and is hinged to the rocking arm 62 at the convex shoulder, the supporting body of the fourth shaft seat 67 is arranged along the width direction of the third pressure plate 61, and the convex head is hinged to the rocking arm 62, and a fourth through slot 68 is opened at the end of the third pressure plate 61 at the top of the fourth shaft seat 67, the middle part of the fourth through slot 68 is hinged to the rocking arm 62, and the slot width of the fourth through slot 68 is greater than the width of the rocking arm 62.

[0026] The fourth rotating shaft seat 67 is located on the outside of the bottom plate 1, and includes a convex support body, the convex head of the support body is hinged to the rocker 62, and the outer end of the third pressing plate 61 is provided with a fourth through slot 68, the middle of the fourth through slot 68 is hinged to the rocker 62, and the slot width of the fourth through slot 68 is greater than the width of the rocker 62. The parallelogram linkage mechanism can drive the third pressing plate 61 to translate downward to reach two working positions: one is that the pressing block 63 just fits with the second multi-stranded wire clamping slot group 23 to press and fix the multi-stranded wire; the other is that the third pressing plate 61 is manually moved downward at a position, the pressing block 63 compresses the spring 65 to remain motionless, and the tool assembly 7 continues to move downward with the third pressing plate 61 to cut the multi-stranded wire.

[0027] In the second working position, since the downward stroke of the third pressure plate 61 is large, in order to avoid interference between the rocker arm 62 and the third pressure plate 61, the two ends of the rocker arm 62 are respectively hinged on the middle part of the fourth through groove 68 and the convex head of the convex U-shaped support body of the fourth rotating shaft seat 67. In this way, during the downward movement of the third pressure plate 61, the rocker arm 62 body can rotate to penetrate into the fourth through groove 68. At the same time, the convex shoulder plane of the convex U-shaped support body can be limited at the junction with the bottom surface on both sides of the fourth through groove 68, limiting the farthest point of the downward stroke of the third pressure plate 61, thereby achieving the purpose of limiting the downward cutting depth of the tool assembly 7, and the cutting depth is designed to just cut off multiple strands of wire.

[0028] Optionally, a lower travel limit block 69 is provided at the bottom of the third pressing plate 61 on both sides of the fourth through slot 68. The lower travel limit block 69 is used to fit and limit with the shoulder plane of the fourth rotating shaft seat 67. By changing the thickness of the lower travel limit block 69, the stroke of the tool assembly 7 can be designed.

[0029] When two third pressure plate mechanisms 6 are designed symmetrically, the inner third rotating shaft seat 66 can be shared. The third rotating shaft seat 66 also has a convex support body. Unlike the fourth rotating shaft seat 67, its support body is arranged along the length direction of the third pressure plate 61, and the rocker 62 is hinged on the convex shoulder of the support body. In this way, when the third pressure plate 61 is opened upward, the rocker 62 will contact the convex head of the third rotating shaft seat 66 and cannot continue to open. At this time, the rocker 62 is in a tilted state, so that the third pressure plate 61 is kept at the highest point, which is convenient for placing multi-strand wires into the second multi-strand wire slot group 23.

[0030] In short, the upward and downward strokes of the third pressing plate 61 are limited respectively by the third rotating shaft seat 66 and the fourth rotating shaft seat 67 and set within a specified range, which facilitates the opening, pressing and cutting operations and is easy to use.

[0031] Optionally, an oblong opening countersunk hole 611 is provided on the side of the third pressing plate 61, and the third pressing plate 61 is fixedly connected to the tool assembly 7 by screws passing through the opening countersunk hole 611. By tightening the screws at different positions of the oblong opening countersunk hole 611, the cutting position of the tool assembly 7 can be finely adjusted, thereby being suitable for wire processing with different lengths of multiple strands retained.

[0032] Optionally, the tool assembly 7 includes a tool holder 71 and a blade 72. The tool holder 71 is block-shaped, the top surface of which is fixed to the third pressing plate 61, and the bottom surface is provided with a slot, and the blade 72 is embedded in the slot of the tool holder 71 and aligned with the cutting groove 3. Screws are provided on the side of the tool holder 71 to fasten the blade 72. At the same time, in order to avoid the tool assembly 7 during the downward movement, the side of the pressing block 63 close to the tool assembly 7 is provided with a stepped surface and an opening.

[0033] Optionally, a hole is formed on the main body of the pressing block 63, and a third magnet is embedded in the hole. The long strip-shaped protrusion of the second multi-stranded wire slot group 23 is made of a magnetic metal material, such as iron, cobalt, nickel and alloys thereof. The pressing block 63 is adsorbed on the second multi-stranded wire slot group 23 by magnetic force, and the head of the multi-stranded wire is pressed tightly, which is fast to fix and easy to open.

[0034] like Figure 5 As shown, the first pressing plate mechanism 4 includes a first pressing plate 41, one end of which is hinged to one side of the wire slot group 21, and the other end of the first pressing plate 41 is openably connected to the other side of the wire slot group 21. The first pressing plate 41 is opened and closed in a flipping manner, and its free end can be connected to the bottom plate 1 by a Velcro adhesive, magnetic attraction, buckle or other openable and closable manner, which is very convenient to open and close when in use.

[0035] Optionally, the first pressure plate mechanism 4 also includes a first rotating shaft seat 42 and a fixed seat 43, the first rotating shaft seat 42 and the fixed seat 43 are respectively fixed on both sides of the wire slot group 21, one end of the first pressure plate 41 is hinged on the first rotating shaft seat 42, and the other end of the first pressure plate 41 is a movable end, and is magnetically attracted to the fixed seat 43. The first pressure plate 41 is pressed on the wire slot group 21 in a flipped form. After flipping up, sufficient space can be reserved for placing the wire; after flipping down, its movable end is directly adsorbed and fixed to the fixed seat 43 by magnetic force, and a little force is applied when opening, which is very convenient to use. When two first pressure plate mechanisms 4 are symmetrically arranged on the left and right, a fixed seat 43 can be shared, which simplifies the design and saves costs.

[0036] In order to facilitate opening of the first pressing plate mechanism 4, a first handle 45 is provided on the top surface of the movable end of the first pressing plate 41. The first handle 45 extends vertically out of the side of the first pressing plate 41 to facilitate applying force to open the magnetic adsorption between its movable end and the fixing seat 43.

[0037] Furthermore, a hole is formed at the movable end of the first pressing plate 41, and a first magnet 44 is embedded in the hole. The fixing seat 43 is made of magnetic metal material, such as iron, cobalt, nickel and alloys thereof.

[0038] Optionally, the wire slot group 21 is composed of a plurality of first through slots 211 formed by a long strip-shaped protrusion on the surface of the bottom plate 1. The wire slot group 21 is used to place or insert the wire body, and the slot is designed to protrude from the surface of the bottom plate 1, which is convenient for manual insertion of the wire. In order to compress the wire, the groove depth of the first through slot 211 is less than the diameter of the wire.

[0039] like Figure 6 As shown, the first multi-stranded wire slot group 22 is composed of a plurality of second through slots 221 formed by a long strip-shaped protrusion on the surface of the bottom plate 1. The second through slot group 221 is used to house or insert the tail of the multi-stranded wire. It is similar to the structure of the wire slot group 21. It is also designed to protrude from the surface of the bottom plate 1 to facilitate placement. But the difference is: each wire body corresponds to multiple multi-stranded wires, so the number of slots in each first group of second through slots 221 is not less than the number of multi-stranded wires of the wire, and the slot height and slot width of the second through slot 221 are much smaller than the first through slot 211, so as to ensure that the center of the inserted multi-stranded wire is at the same height as the center of the wire body.

[0040] Similarly, the structure of the second multi-strand wire slot group 23 is the same as that of the first multi-strand wire slot group 22. It is composed of a plurality of groups of third through slots 231 formed by long strip-shaped protrusions on the surface of the base plate 1. The number of slots in each group of third through slots 231 is not less than the number of multiple strands of the wire.

[0041] Optionally, the second pressure plate mechanism 5 includes a second pressure plate 51 and a second rotating shaft seat 52, the second rotating shaft seat 52 is fixed on one side of the first multi-strand wire slot group 22, one end of the second pressure plate 51 is hinged on the second rotating shaft seat 52, and the other end of the second pressure plate 51 is a movable end, and is magnetically attracted to the long strip protrusion of the first multi-strand wire slot group 22.

[0042] The second pressing plate mechanism 5 is similar in structure to the first pressing plate mechanism 4, except that: since the diameter of the multi-stranded wire is relatively small and the second through slot 221 is relatively shallow, the movable end of the second pressing plate 51 is directly adsorbed and fixed on the long strip-shaped protrusion forming the first multi-stranded wire slot group 22, saving the manufacturing cost of the clamping structure. The similarities are: the movable end of the second pressing plate 51 is provided with a hole, and the inside of the hole is embedded with a second magnet 53, and the long strip-shaped protrusion of the first multi-stranded wire slot group 22 is made of magnetic metal material, such as iron, cobalt, nickel and its alloy. A second handle 54 is provided on the top surface of the movable end of the second pressing plate 51.

[0043] like Figure 7 As shown, the clamping mechanism further includes a clamp base 8 , and blocks 81 are provided on the top and side edges of the surface of the clamp base 8 , and the blocks 81 are magnetically attracted to the side edges of the bottom plate 1 .

[0044] Optionally, a fourth magnet is embedded on two adjacent sides of the bottom plate 1 and the stopper 81, for being fixed by adsorption with the stopper 81. A pair of handles 11 are provided on both sides of the bottom plate 1 to facilitate carrying the bottom plate 1 and the clamping mechanism thereon as a whole.

[0045] The clamp base 8 is the mother body of the base plate 1, and is fixedly placed on the processing station of the laser equipment. On the production line, the clamping mechanism on the base plate 1 is mobile as a whole. After placing and clamping a number of wires on the clamping mechanism of the base plate 1, the handle 11 is used to move the clamping mechanism of the entire base plate 1 and the wires thereon to the clamp base 8, and the fourth magnet on the side of the base plate 1 is adsorbed and fixed with the block 81. The overall positioning is completed, and the laser equipment can be turned on to perform laser cutting on the multi-strand wires. After the cutting is completed, the base plate 1 is removed from the clamp base 8 as a whole by the handle 11, and the third pressing plate 61 is manually pressed to cut the heads of the multi-strand wires. Then, the first pressing plate 41 and the second pressing plate 51 are opened to remove the wires with the same stripping size, clean the waste on the base plate 1, and place new wires on the base plate 1. The processing is repeated in a cycle. When the wires are used, the wrapping layer cut off the multi-strand wires is removed.

[0046] It should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
