Description

Technical Field

[0001] The invention relates to the field of cable automation processing equipment, in particular to a full-automatic stripping and riveting machine with a mid-stripping function. Background Art

[0002] With the development of modern electronic technology, the demand for wires has also increased significantly. For manufacturers, the opportunities are great but the competition is also great. They need to improve production efficiency and reduce production costs.

[0003] Existing wire insulation stripping generally uses a ring cutting process, which correspondingly reduces its processing efficiency. For example, Chinese patent 202310573142.6 mainly realizes stripping of the middle part, but its mechanism is relatively complex and the connection and coordination between various machines require high precision. Therefore, in actual operation, frequent alignment is required to ensure continuous processing. Summary of the Invention

[0004] The main purpose of the present invention is to propose a fully automatic stripping and riveting machine with a middle stripping function, which aims to improve the existing stripping mechanism, can realize the stripping of the insulation layer in the middle of the cable, and has a simple and stable structure. While improving the processing efficiency, it can cooperate with the terminal riveting and has stable processing.

[0005] To achieve the above object, the present invention provides a fully automatic peeling and riveting machine with a mid-stripping function, comprising:

[0006] A machine base, wherein the machine base is provided with a feeding device, a peeling mechanism and a clamping and moving mechanism;

[0007] The feeding device is used to transport the middle part of a single cable to the stripping mechanism;

[0008] The peeling mechanism is arranged in front of the feeding device, and the peeling mechanism includes a first vertical moving device, a skin-breaking knife arranged on the first vertical moving device, and a front peeling knife and a rear peeling knife arranged on the first vertical moving device. The front peeling knife and the rear peeling knife are arranged in the same longitudinal direction and are spaced apart. The skin-breaking knife, the front peeling knife and the rear peeling knife are respectively provided with two and spaced apart.

[0009] The first vertical moving device can drive the two skin-breaking knives, the two front stripping knives and the rear stripping knife to move between positions close to each other and positions away from each other;

[0010] The clamping movement mechanism includes a first transverse movement device, a first longitudinal movement device provided on the first transverse movement device, and a clamping claw device provided on the first longitudinal movement device.

[0011] When the feeding device moves the cable to the skin-breaking knife, the skin-breaking knife can cut a predetermined groove on two opposite sides of the cable insulation layer in the length direction.

[0012] The feeding device drives the cable with the cutting groove to move to the front stripping knife, and makes the front stripping knife cut the first circumferential groove and the second circumferential groove along the front and rear ends of the cutting groove. At the same time, the rear stripping knife clamps the position of the first circumferential groove, and then the clamping claw device drives the protruding part of the cable to move, and the insulation layer is stripped and falls between the front stripping knife and the rear stripping knife.

[0013] In actual work, the feeding device can drive the middle part of the cable to move to the position of the stripping mechanism, thereby ensuring that the skin breaking and insulation stripping work at the same time. First, the setting of the two skin breaking knives avoids the problem that the existing circumferential cutting and stripping can only achieve complete insulation falling. At the same time, the front stripping knife is used to cut the first and second circumferential grooves, and the rear stripping knife is used to limit the stripped insulation layer. The clamping moving mechanism drives the clamping claw device to drive the cable to move, thereby achieving insulation stripping. Its structure is simple and the rhythm is stable, which can effectively improve processing efficiency.

[0014] In actual processing, including terminal riveting, visual inspection and other processes, 50-80 cables can be processed in 1 minute, effectively improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] like Figures 1 to 11 As shown, a fully automatic peeling and riveting machine with a mid-stripping function includes:

[0040] A machine base 1, wherein the machine base 1 is provided with a feeding device 11, a peeling mechanism 2 and a clamping and moving mechanism;

[0041] The feeding device 11 is used to transport the middle portion of a single cable 100 to the stripping mechanism 2 (the middle portion is not limited and mainly refers to a position away from the end);

[0042] The peeling mechanism 2 is arranged in front of the feeding device 11, and the peeling mechanism 2 includes a first vertical moving device 6, a skin-breaking knife arranged on the first vertical moving device 6, and a front peeling knife and a rear peeling knife arranged on the first vertical moving device 6. The front peeling knife and the rear peeling knife are arranged in the same longitudinal direction and are spaced apart. The skin-breaking knife, the front peeling knife and the rear peeling knife are respectively provided with two and spaced apart.

[0043] The first vertical moving device 6 can drive the two skin-breaking knives, the two front stripping knives and the rear stripping knife to move between positions close to each other and away from each other;

[0044] The clamping movement mechanism includes a first transverse movement device 71, a first longitudinal movement device 72 provided on the first transverse movement device 71, and a clamping claw device 73 provided on the first longitudinal movement device 72.

[0045] When the feeding device 11 moves the cable 100 to the skin-breaking knife, the skin-breaking knife can cut predetermined grooves 102 on two opposite sides of the insulation layer 101 of the cable 100 in the length direction.

[0046] The feeding device 11 drives the cable 100 provided with the cutting groove 102 to move to the front stripping knife, and causes the front stripping knife to cut the first circumferential groove 103 and the second circumferential groove 104 along the front and rear ends of the cutting groove 102. At the same time, the rear stripping knife clamps the position of the first circumferential groove 103, and then the clamping claw device 73 drives the protruding part of the cable 100 to move, and causes the insulation layer 101 to be peeled off and fall between the front stripping knife and the rear stripping knife.

[0047] In actual work, the feeding device 11 can drive the cable 100 to move, thereby ensuring that the skin breaking and the insulation stripping 101 work at the same time. First, by setting the two skin breaking knives, the problem that the existing circumferential cutting and stripping can achieve the complete falling of the insulation layer 101 is avoided. At the same time, the front stripping knife is used to cut the first circumferential groove 103 and the second circumferential groove 104, and the rear stripping knife is used to limit the stripped insulation layer 101. The clamping and moving mechanism drives the clamping claw device 73 to drive the cable 100 to move, thereby realizing the stripping of the insulation layer 101. The stripping of the insulation layer in the middle of the cable is realized through the cooperation of various mechanisms. It has a simple structure and a stable rhythm, which can effectively improve the processing efficiency.

[0048] In actual processing, including terminal riveting, visual inspection and other processes, 50-80 cables 100 can be processed in 1 minute, effectively improving production efficiency.

[0049] Specifically, the feeding device 11 includes a transverse feeding moving device, a longitudinal feeding moving device provided on the transverse feeding moving device, and a conductor structure provided on the longitudinal feeding moving device. The transverse feeding moving device and the longitudinal feeding moving device can drive the conductor structure to move transversely and longitudinally;

[0050] A first visual inspection device 91 is provided between the feeding device 11 and the stripping mechanism 2. This first visual inspection device is used to detect the ends of the cable 100. Specifically, the transverse and longitudinal feeding mechanisms cooperate to enable the guide structure to move the cable 100 and insert it between the skin-breaking and front-stripping blades. The feeding device 11 is prior art, as described in Chinese Patent No. 202311469688.3. The first visual inspection device can be used to detect a predetermined position and determine whether it meets the requirements.

[0051] Specifically, the first vertical moving device 6 includes a first vertical frame 60, an upper slider 61 and a lower slider 62 slidably mounted on the first vertical frame, the first vertical frame is provided with a first ball screw 63, the upper slider and the lower slider are provided with a first screw nut and a second screw nut that cooperate with the first ball screw, the first ball screw is connected to the first rotating device 64, and the first rotating device can drive the upper slider and the lower slider to move between positions close to and away from each other.

[0052] Specifically, the skin-breaking knife includes an upper skin-breaking knife 31 and a lower skin-breaking knife 32, and the upper skin-breaking knife 31 and the lower skin-breaking knife 32 are respectively installed on the upper slider and the lower slider;

[0053] The front stripping knife includes an upper front stripping knife 41 and a lower front stripping knife 42, and the upper front stripping knife and the lower front stripping knife form a cutting groove. The upper front stripping knife 41 and the lower front stripping knife 42 are arranged at positions adjacent to the upper skin-breaking knife 31 and the lower skin-breaking knife 32;

[0054] The rear stripping knife includes an upper rear stripping knife 51 and a lower rear stripping knife 52, and the upper rear stripping knife and the lower rear stripping knife are arranged at positions adjacent to the upper skin-breaking knife 31 and the lower skin-breaking knife 32;

[0055] A material suction trough 12 is provided between the front stripping blade and the rear stripping blade, and the material suction trough 12 is used to collect the stripped insulation layer 101 .

[0056] In a specific embodiment, the skin breaking knife, the front stripping knife and the rear stripping knife are arranged on the same driving device, which can realize relative movement and synchronous skin breaking and stripping, making the whole mechanism structure smaller and the equipment cost lower.

[0057] Of course, two sets of driving mechanisms can also be used to drive the skin-breaking knife and the front peeling knife + rear peeling knife respectively, so as to achieve the dislocation of processing.

[0058] The upper front stripping knife 41 and the upper rear stripping knife are arranged on the same seat, and the lower front stripping knife and the lower rear stripping knife are arranged on the same seat, thereby improving processing consistency and making installation simpler.

[0059] Specifically, the upper skin-breaking knife 31 and the lower skin-breaking knife 32 are respectively mounted on the upper knife seat 301 and the lower knife seat 302. A positioning groove 303 is recessed in the middle of the lower knife seat 302. The lower skin-breaking knife 32 is arranged in the positioning groove 303 and partially extends out. An inclined guide surface 305 is provided on both sides of the positioning groove 303.

[0060] The upper knife seat 301 is provided with a positioning protrusion 304 having a shape matching that of the positioning groove 303 , and the upper skin-breaking knife 31 extends out of the bottom wall of the positioning protrusion 304 .

[0061] The guide surface 305 allows the cable 100 to slide accurately into the positioning groove 303. When breaking the cable 100, the upper and lower blades 31 and 32 move closer to each other, thereby cutting a groove 102 of a predetermined length on the upper and lower walls of the cable 100. The insertion of the groove 102 (i.e., the movement distance between the upper and lower blades 31 and 32) is mainly determined by not damaging the battery cell structure.

[0062] Specifically, the upper front stripping knife 41, the lower front stripping knife, the upper rear stripping knife and the lower rear stripping knife have the same structure, including a knife body 21, a straight wall 22 provided on one side of the knife body 21 and a blade portion 23 recessed on the other side of the knife body, the blade portion 23 is provided with a diamond-shaped or arc-shaped blade groove 24, and the blade portion 23 is provided with an inclined blade surface 25. When the two knife bodies 21 are tangent to each other, the straight walls 22 fit together, so when the two blade portions 23 are close to each other, they can form a first circumferential groove 103 and a second circumferential groove 104 that are suitable for the size of the insulation layer 101 of the cable 100, thereby realizing the ring cutting of the outer insulation layer 101 of the cable 100, which can be partially completely cut, and partially cut without affecting the stripping of the insulation layer 101 by the rear stripping knife; wherein this structure has higher ring cutting efficiency,

[0063] At the same time, the lower rear stripping knife can be directly slid into the material suction trough 12 by the inclined blade surface 25 .

[0064] The blade body 21 of the same structure can also save some maintenance costs, and the replacement of the blade body and the adjustment of the stroke data can also facilitate the processing of cables 100 with different diameters.

[0065] Specifically, the blade surface 25 is provided with two cutting angles, wherein the cutting angle can be set according to the shape or diameter of the wire, for example, 90 degrees.

[0066] In the embodiment of the present invention, the first transverse moving device 71 includes a transverse guide rail, a transverse slider provided on the transverse guide rail, and a transverse screw pair for driving the transverse slider to move;

[0067] The first longitudinal moving device 72 includes a longitudinal guide rail provided on the transverse slider, a longitudinal slider provided on the longitudinal guide rail, and a longitudinal screw pair for driving the longitudinal slider;

[0068] The clamping device 73 includes a telescopic motor 730 provided on the longitudinal slider and a first clamping jaw 731 and a second clamping jaw 732 pivotally mounted on the longitudinal slider. The rear ends of the first clamping jaw and the rear ends of the second clamping jaw are provided on the same pivot axis, and the pivot axis is connected to the telescopic motor 730. The telescopic motor 730 can drive the first clamping jaw and the second clamping jaw to move between positions close to each other and positions away from each other.

[0069] Specifically, the first clamping jaw and the second clamping jaw are respectively provided with a prismatic groove 81 and a prismatic portion 82 , and at least two groups of staggered grooves 83 and clamping portions 84 are provided on the prismatic groove 81 and the prismatic portion, thereby improving the stability of clamping the cable 100 and preventing slipping.

[0070] The stripping mechanism 2 is also provided with a supporting device and an inclined guide platform 95. The supporting device is used to support the end of the cable 100 when the clamping moving mechanism is away from the stripping device, and to move the front end of the cable 100 to the transport device (it can be supported or it can drive the cable 100 to move). The guide platform 95 is used to slide the cable 100 to the riveting station after processing, avoiding the problem of winding. The structure is simple and stable, and effectively reduces interference.

[0071] It also includes a riveting device 9, and the clamping moving mechanism can drive the stripped cable 100 to move to the riveting device 9. A second lateral moving device 93 is also provided on one side of the riveting device 9, and the second lateral moving device is provided with a manipulator 94. The riveting device 9 is also provided with a second visual inspection device 92, and the second lateral moving device is used to drive the clamping mechanism to move between the riveting device 9, the second visual inspection device 92 and the unloading position 96.

[0072] When the clamping and moving mechanism moves the cable 100 to the riveting device 9, the manipulator simultaneously clamps and fixes the cable 100, and then the clamping and moving mechanism is reset, thereby achieving high-speed stripping and riveting;

[0073] Of course, the specific riveting device 9 can also be a welding device, etc., and then processed after stripping, wherein the second visual inspection device 92 is used to detect whether the terminal meets the predetermined standard.

[0074] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
