Description

Technical Field

[0001] This invention belongs to the field of diamond wire testing, and specifically relates to an automatic diamond wire testing device. Background Technology

[0002] Diamond wire is made by uniformly bonding diamond micro-powder particles to a high-strength matrix (such as carbon steel wire or tungsten wire) at a specific distribution density using a specific processing method. Diamond wire is mainly used in the photovoltaic silicon wafer industry, and the quality and stability of photovoltaic silicon wafers are closely related to the quality of the diamond wire. The performance of diamond wire is mainly determined by the following parameters: wire pitch and diameter, outer envelope diameter, cutting edge rate, number of abrasive grains, agglomerate formation, and breaking strength, etc.

[0003] However, existing diamond wire testing requires multiple different testing devices for various categories of tests, which is complicated in terms of material loading and has a low degree of automation, resulting in low efficiency in diamond wire performance testing. Summary of the Invention

[0004] In view of the above-mentioned defects or improvement needs of the existing technology, the present invention provides an automatic diamond wire inspection device, the purpose of which is to not only realize continuous feeding of multiple inspection stations, but also to automatically perform various types of performance tests, thereby greatly improving inspection efficiency.

[0005] To achieve the above objectives, the present invention provides an automatic diamond wire testing device, which includes a support platform, a feeding assembly, an appearance inspection assembly, and a tensile strength detection assembly. The feeding assembly includes a wire reel, a first displacement component, a first gripper, an automatic shear, a displacement module, a first rotating component, a rotating arm, and two second grippers. The wire reel, the first displacement component, the automatic shear, and the displacement module are all located on the support platform. The wire reel is used to unwind diamond wire. The first displacement component is used to drive the first gripper to move along a first direction. The automatic shear is used to cut the diamond wire unwound by the wire reel. The displacement module is used to drive the first rotating component to move along a first direction, a second direction, and a third direction. The first rotating component is used to drive the middle part of the rotating arm to rotate, thereby driving the rotating arm to rotate in the vertical planes corresponding to the first direction and the third direction. The two second grippers are respectively arranged at both ends of the rotating arm. The appearance inspection component includes a second displacement member, an appearance camera, and two third grippers spaced apart along a first direction. The second displacement member and the appearance camera are located on the support platform. The second displacement member is used to drive the two third grippers to move along the first direction, and the appearance camera is used to take pictures of the diamond wire. The tensile strength detection assembly includes a first bracket, a force sensor, a third displacement member, and two fourth grippers spaced apart along a third direction. The first bracket is located on the support platform, the force sensor is located on the first bracket, and a fourth gripper is attached to the detection end of the force sensor along a third direction. The third displacement member is used to drive the other fourth gripper to move in a direction away from the force sensor. The first gripper, the second gripper, the third gripper, and the fourth gripper are all used to clamp diamond wire.

[0006] Optionally, the automatic diamond wire detection device further includes a torsion detection component. The torsion detection component includes a second rotating member, two fifth grippers spaced apart along a first direction, a pull rope, and a counterweight. The second rotating member is located on the support platform and is used to drive one of the fifth grippers to rotate. The other fifth gripper is slidably arranged on the support platform along the first direction. One end of the pull rope is connected to the other fifth gripper, and the other end of the pull rope is hooked to the counterweight along a third direction to generate a pulling force on the other fifth gripper away from the second rotating member. The fifth grippers are used to clamp the diamond wire.

[0007] Optionally, the torsion detection assembly further includes an elastic block for limiting another of the fifth jaws, the elastic block being located on the support platform and between the counterweight and the other of the fifth jaws.

[0008] Optionally, the automatic diamond wire detection equipment further includes a curling detection component, which includes a glass plate, a second support, a diameter camera, and a warping camera. The glass plate, the second support, and the warping camera are all located on the support platform. The glass plate is arranged in a horizontal plane corresponding to the first and second directions to support freely falling diamond wires. The diameter camera is located on the second support and is used to take top-down photos of the diamond wires on the glass plate. The warping camera is used to take side-view photos of the diamond wires on the glass plate.

[0009] Optionally, the warping detection assembly further includes a horizontal light source and a vertical light source, the horizontal light source being arranged parallel between the glass plate and the support platform, the vertical light source being located on one side of the glass plate, and the glass plate being located between the warping camera and the vertical light source.

[0010] Optionally, the appearance inspection component further includes a movable plate, a fourth displacement member, and two positioning posts arranged at intervals along a first direction. The second displacement member is used to drive the movable plate to move along the first direction. The fourth displacement member and the two third grippers are both located on the movable plate.

The positioning posts are arranged along a third direction and are used to push the diamond wire to the target position.

[0011] Optionally, the outer periphery of the end of the positioning post facing away from the support platform has an annular groove for accommodating the diamond wire. The annular groove is a conical groove to position the diamond wire in a third direction.

[0012] Optionally, the tensile testing assembly further includes a first support and a second support. The first support is attached to the detection end of the force sensor along a third direction. The first support has a first motor, and the output shaft of the first motor is connected to one of the fourth grippers to rotate the fourth gripper.

[0014] Optionally, the support platform has a third support, the third support has a threading block, the threading block and the thread reel are arranged at intervals on the third support, the threading block is provided with a threading hole, the threading hole is used for the diamond wire to pass through in the first direction.

[0015] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0016] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include: In the diamond wire automatic inspection device provided in this embodiment of the invention, when inspecting diamond wire, firstly, the diamond wire sample is wound onto a spool, and one end of the diamond wire is clamped by a first gripper. Then, a first displacement component moves the first gripper, straightening the diamond wire a certain distance from the spool. Next, a displacement module drives a first rotating component and a rotating arm to the position of the diamond wire, where two second grippers simultaneously clamp the diamond wire. At this point, the first grippers release their clamping action, and an automatic shear cuts the diamond wire, allowing the two second grippers to hold a section of the diamond wire sample. Afterward, the displacement module can move the cut diamond wire to the appearance inspection component or the tensile strength inspection component, while the first displacement component and other structures can repeatedly perform material handling, ensuring uninterrupted feeding to the appearance inspection component and the tensile strength inspection component.

[0017] For the appearance inspection component, the displacement module moves the diamond wire to a set position using two second grippers, and then two third grippers simultaneously clamp both ends of the diamond wire (at this point, the rotating arm does not need to rotate). Afterward, the second displacement component drives the two third grippers and the diamond wire to move, while the displacement module moves and resets for the next loading cycle. The appearance camera takes pictures of different positions on the diamond wire, acquiring appearance images of each segment. Subsequent analysis and processing of these photos yields appearance parameters of the diamond wire, including wire pitch, wire diameter, outer envelope diameter, cutting edge rate, number of sand grains, and sand inclusions.

[0018] For the tensile strength testing component, the displacement module moves the next section of diamond wire to a set position via two second grippers. Then, a rotating component drives the arm to rotate 90° clockwise (or 90° counter-clockwise, i.e., from the first direction to the third direction). At this point, the two fourth grippers clamp the diamond wire, and the displacement module moves to its reset position for the next loading. The force sensor is first zeroed and tare-tested. Then, the third displacement component drives the lower fourth grippers downwards until the diamond wire is broken. The breaking force of the diamond wire can then be read from the force sensor. Furthermore, during the tensile strength test, the rotation of the arm ensures that the gravity of the fourth grippers and the tension force applied to the diamond wire are both along the third direction (i.e., the directions of the two forces are coaxial), avoiding the problem of torque caused by different directions of action, thus ensuring the accuracy of the tensile strength obtained from the test.

[0019] In other words, the automatic diamond wire testing equipment provided in this embodiment of the invention integrates a feeding component, an appearance inspection component, and a tensile breakage inspection component. It can not only achieve continuous feeding of multiple testing stations, but also automatically perform various types of performance tests, greatly improving testing efficiency.

Figure 1 As shown, the diamond wire automatic testing equipment includes a support platform 1, a feeding assembly 2, an appearance inspection assembly 3, and a tensile breakage inspection assembly 4.

Figure 3 This is a schematic diagram of the second partial structure of the feeding assembly provided in an embodiment of the present invention. Figure 4 This is a schematic diagram of the first state of the rotating arm provided in an embodiment of the present invention. Figure 5 This is a schematic diagram of the second state of the rotating arm provided in an embodiment of the present invention, combined with... Figures 2-5 As shown, the feeding assembly 2 includes a wire reel 21, a first displacement member 22, a first gripper 23, an automatic shear 24, a displacement module 25, a first rotating member 26, a rotating arm 27, and two second grippers 28. The wire reel 21, the first displacement member 22, the automatic shear 24, and the displacement module 25 are all located on the support platform 1. The wire reel 21 is used to unwind the diamond wire 100. The first displacement member 22 is used to drive the first gripper 23 to move along a first direction. The automatic shear 24 is used to cut the diamond wire 100 unwound by the wire reel 21. The displacement module 25 is used to drive the first rotating member 26 to move along a first direction (e.g., the X direction), a second direction (e.g., the Y direction), and a third direction (e.g., the Z direction). The first rotating member 26 is used to drive the middle part of the rotating arm 27 to rotate, so as to drive the rotating arm 27 to rotate in the vertical plane corresponding to the first direction and the third direction. The two second grippers 28 are respectively arranged at both ends of the rotating arm 27.

[0029] Figure 6 This is a schematic diagram of the appearance inspection component provided in an embodiment of the present invention, as shown below. Figure 6 As shown, the appearance inspection component 3 includes a second displacement member 31, an appearance camera 32, and two third grippers 33 arranged at intervals along a first direction. The second displacement member 31 and the appearance camera 32 are located on the support platform 1. The second displacement member 31 is used to drive the two third grippers 33 to move along the first direction, and the appearance camera 32 is used to take pictures of the diamond wire 100.

[0030] Figure 7 This is a schematic diagram of the tensile strength detection component provided in an embodiment of the present invention, as shown below. Figure 7 As shown, the tensile testing assembly 4 includes a first bracket 41, a force sensor 42, a third displacement member 43, and two fourth grippers 44 arranged at intervals along a third direction. The first bracket 41 is located on the support platform 1, and the force sensor 42 is located on the first bracket 41. A fourth gripper 44 is attached to the detection end of the force sensor 42 along a third direction. The third displacement member 43 is used to drive the other fourth gripper 44 to move in the direction away from the force sensor 42. The first gripper 23, the second gripper 28, the third gripper 33, and the fourth gripper 44 are all used to clamp the diamond wire 100.

[0031] In the automatic diamond wire inspection device provided in this embodiment of the invention, when inspecting the diamond wire 100, firstly, the diamond wire 100 sample is wound onto the reel 21, and one end of the diamond wire 100 is clamped by the first gripper 23. Then, the first displacement member 22 moves the first gripper 23, causing the diamond wire 100 to be straightened a certain distance from the reel 21. Next, the displacement module 25 drives the first rotating member 26 and the rotating arm 27 to the position of the diamond wire 100, and the two second grippers 28 simultaneously clamp the diamond wire 100. At this time, the first gripper 23 releases its grip, and the automatic shears 24 cuts the diamond wire 100, allowing the two second grippers 28 to clamp a section of the diamond wire 100 sample. Afterwards, the displacement module 25 can move the cut diamond wire 100 to the appearance inspection component 3 or the tensile strength inspection component 4, while the first displacement member 22 and other structures can repeatedly perform material handling, ensuring uninterrupted feeding of the appearance inspection component 3 and the tensile strength inspection component 4.

[0032] For the appearance inspection component 3, after the displacement module 25 moves the diamond wire 100 to the set position via the two second grippers 28, the two third grippers 33 simultaneously clamp both ends of the diamond wire 100 (at this time, the rotating arm 27 does not need to rotate). Then, the second displacement component 31 drives the two third grippers 33 and the diamond wire 100 to move, while the displacement module 25 moves and resets for the next loading. The appearance camera 32 takes pictures of different positions on the diamond wire 100 to obtain appearance images of each segment of the diamond wire 100. Subsequent analysis and processing of these photos can obtain appearance parameters of the diamond wire 100, such as wire pitch, wire diameter, outer diameter envelope, cutting edge rate, number of sand grains, and sand agglomerates.

[0033] For the tensile strength detection component 4, after the displacement module 25 moves the next section of diamond wire 100 to the set position via the two second grippers 28, it drives the rotating arm 27 to rotate 90° clockwise (or 90° counterclockwise, i.e., from the first direction to the third direction) via the rotating component. At this time, the two fourth grippers 44 clamp the diamond wire 100, and the displacement module 25 moves and resets for the next loading. The force sensor 42 is first zeroed and tare, and then the third displacement component 43 drives the lower fourth gripper 44 to move down until the diamond wire 100 is broken. At this time, the breaking force of the diamond wire 100 can be read by the force sensor 42. In addition, during the tensile strength test, due to the rotation of the rotating arm 27, the gravity of the fourth gripper 44 and the tension force provided to the diamond wire 100 are both along the third direction (that is, the directions of the two forces are coaxial), avoiding the problem of torque caused by the different directions of the two forces, thus ensuring the accuracy of the tensile strength obtained by the test.

[0034] In other words, the automatic diamond wire testing equipment provided in this embodiment of the invention integrates the feeding component 2, the appearance inspection component 3, and the tensile strength inspection component 4. It can not only realize continuous feeding of multiple inspection stations, but also automatically perform various types of performance tests, which greatly improves the testing efficiency.

[0035] For example, the gripper can be a pneumatic gripper.

[0036] It should be noted that in this embodiment, the grippers are of different sizes or have corresponding clearance grooves, which can effectively avoid interference during the clamping of the diamond wire 100 between different grippers.

[0037] For example, the automatic shears 24 can be pneumatic or electric, and can automatically realize the shearing motion. The displacement module 25 includes two first support frames 251, an X-axis linear module 252, a Y-axis linear module 253, a Z-axis linear module 254, and a fixed plate 255. The two first support frames 251 are arranged in parallel and spaced apart. The X-axis linear module 252 is located on one first support frame 251, and a slide rail is provided on the other first support frame 251. The two ends of the Y-axis linear module 253 are respectively set on the output end of the X-axis linear module 252 and the slide rail. The Z-axis linear module 254 is set on the output end of the Y-axis linear module 253, and the fixed plate 255 is set on the output end of the Z-axis linear module 254. The first rotating component 26 is mounted on the fixed plate 255.

[0038] It should be noted that in other embodiments of the present invention, the displacement module 25 may also be a robotic arm, and the present invention does not limit this.

[0039] In addition, two spaced limit blocks 256 are provided on the fixed plate 255 to limit the rotation of the rotating arm 27 to the first direction and the third direction, respectively.

[0040] Figure 8 This is a schematic diagram of the structure of the second gripper provided in an embodiment of the present invention, as shown below. Figure 8 As shown, the output end of the second gripper 28 corresponds to two clamping blocks 281, thereby clamping the diamond wire 100. A flexible thin-film sensor 282 and a wear-resistant plate 283 are respectively disposed on the inner side of each clamping block 281, wherein the flexible thin-film sensor 282 is located between the wear-resistant plate 283 and the clamping block 281. The flexible thin-film sensor 282 can record the clamping force of the clamping block 281 on the diamond wire 100, and adjust the second gripper 28 online according to this clamping force to avoid excessive clamping force that could damage the diamond wire 100. The wear-resistant plate 283 directly contacts the diamond wire 100, preventing the flexible thin-film sensor 282 from being worn.

[0041] See also Figure 2The feeding assembly 2 also includes a fifth displacement member 29, which drives the automatic shears 24 to move along the second direction. The fifth displacement member 29 can drive the automatic shears 24 to move, which not only increases the reliability of the automatic shears 24, but also reduces the space it occupies.

[0042] In addition, the support platform 1 has a third support 11, and the third support 11 has a threading block 111. The threading block 111 and the thread reel 21 are arranged at intervals on the third support 11. The threading block 111 is provided with a threading hole for the diamond wire 100 to pass through in the first direction.

[0043] It is easy to understand that the threading block 111 can not only guide the thread reel 21 when it is feeding the thread to prevent the diamond wire 100 from springing back or falling off after being cut, but also remove stains from the surface of the diamond wire 100.

[0044] Figure 9 This is a schematic diagram of the structure of the torsion detection component provided in an embodiment of the present invention, as shown below. Figure 9 As shown, the diamond wire automatic detection equipment also includes a torsion detection component 5. The torsion detection component 5 includes a second rotating member 51, two fifth grippers 52 arranged at intervals along a first direction, a pull rope 53, and a counterweight 54. The second rotating member 51 is located on the support platform 1 and is used to drive one of the fifth grippers 52 to rotate. The other fifth gripper 52 is slidably arranged on the support platform 1 along the first direction. One end of the pull rope 53 is connected to the other fifth gripper 52, and the other end of the pull rope 53 is attached to the counterweight 54 along a third direction to generate a pulling force on the other fifth gripper 52 in the opposite direction to the second rotating member 51. The fifth grippers 52 are used to clamp the diamond wire 100.

[0045] In the above embodiment, the two fifth grippers 52 can receive and clamp the diamond wire 100 transferred from the displacement module 25. Subsequently, the second rotating member 51 drives the corresponding fifth gripper 52 to rotate until the diamond wire 100 breaks. The number of rotations of the rotating end of the second rotating member 51 at this point is recorded, thus obtaining the final number of twists of the diamond wire 100, increasing the detection range of this automatic detection device. Furthermore, the diamond wire 100 will slowly shorten during rotation, causing the corresponding fifth gripper 52 to move. During this movement, the fifth gripper 52, through the counterweight 54, can maintain a constant tension on the diamond wire 100.

[0046] For example, a second support frame 12 is provided on the support platform 1, which raises the torsion detection component 5. A pad 121 is provided on the second support frame 12, and the second rotating component 51 is located on the pad 121, so that the two fifth grippers 52 are at the same height. The fifth gripper 52 on the right side is slidably arranged on the second support frame 12 via a slide rail. A pulley seat 122 is provided on the side of the second support frame 12, and a pulley is provided on the pulley seat 122. The middle part of the pull rope 53 is laid on the pulley, so that the weight of the counterweight 54 is accurately converted into the tension of the diamond wire 100 through the pull rope 53.

[0047] For example, the mass of the counterweight 54 can be 25-50g.

[0048] Furthermore, the torsion detection assembly 5 also includes an elastic block 55 for limiting the other fifth gripper 52. The elastic block 55 is located on the support platform 1 and between the counterweight 54 and the other fifth gripper 52. This elastic block 55 can limit the right fifth gripper 52 to prevent it from breaking after the diamond wire 100 is pulled apart, thereby preventing the fifth gripper 52 from disengaging from the slide rail under the action of the counterweight 54.

[0049] Figure 10 This is a schematic diagram of the structure of the curl detection component provided in an embodiment of the present invention, as shown below. Figure 10 As shown, the diamond wire automatic detection equipment also includes a curling detection component 6. The curling detection component 6 includes a glass plate 61, a second support 62, a diameter camera 63, and a warping camera 64. The glass plate 61, the second support 62, and the warping camera 64 are all located on the support platform 1. The glass plate 61 is arranged in the horizontal plane corresponding to the first and second directions and is used to support the freely falling diamond wire 100. The diameter camera 63 is located on the second support 62 and is used to take a top-down picture of the diamond wire 100 on the glass plate 61. The warping camera 64 is used to take a side-view picture of the diamond wire 100 on the glass plate 61.

[0050] Specifically, the displacement module 25 transfers the diamond wire 100 above the glass plate 61. The first rotating component 26 drives the rotating arm 27 to rotate, causing the diamond wire 100 to rotate and be arranged along a third direction. Next, the lower second gripper 28 releases its grip on the diamond wire 100, followed by the upper second gripper 28 releasing its grip, allowing the diamond wire 100 to fall freely onto the glass plate 61. Finally, the upper diameter camera 63 takes a picture of the diamond wire 100 on the glass plate 61, and through image processing, measures the different diameters formed by different positions of the diamond wire 100. Similarly, the side warp camera 64 takes a picture of the diamond wire 100, and through image processing, measures the warp (gap) formed at various positions of the diamond wire 100 when placed on the glass plate 61, thus increasing the detection range of this automatic detection device.

[0051] For example, the curling detection assembly 6 further includes a sixth displacement member 67 and a seventh displacement member 68, both located on the support platform 1. The sixth displacement member 67 drives the second bracket 62 to move along a first direction, and the second bracket 62 can adjust the position of the diameter camera 63 in a second direction and a third direction. The seventh displacement member 68 drives the warping camera 64 to move along the second direction.

[0052] Furthermore, the warping detection assembly 6 also includes a horizontal light source 65 and a vertical light source 66. The horizontal light source 65 is arranged in parallel between the glass plate 61 and the support platform 1, and the vertical light source 66 is located on one side of the glass plate 61. The glass plate 61 is located between the warping camera 64 and the vertical light source 66.

[0053] In the above embodiment, the horizontal light source 65 and the vertical light source 66 can illuminate the diamond wire 100, ensuring more accurate photography by the diameter camera 63 and the warp camera 64.

[0054] For example, a fourth support frame 13 is provided on the support platform 1, a horizontal light source 65 is horizontally fixed on the fourth support frame 13, and a vertical light source 66 is vertically fixed on the fourth support frame 13. The fourth support frame 13 is recessed on the support platform 1, thereby reducing the space occupied by the second bracket 62 in the third direction.

[0055] See also Figure 6 The appearance inspection component 3 also includes a movable plate 34, a fourth displacement member 35, and two positioning posts 36 arranged at intervals along a first direction. The second displacement member 31 is used to drive the movable plate 34 to move along the first direction. The fourth displacement member 35 and the two third grippers 33 are all located on the movable plate 34. The fourth displacement member 35 is used to drive the two positioning posts 36 to move along the second direction. The positioning posts 36 are arranged along a third direction and are used to push the diamond wire 100 to the target position.

[0056] In the above embodiment, the fourth displacement member 35 drives the two positioning posts 36 to move along the second direction, which in turn pushes the diamond wire 100, thereby achieving precise positioning of the diamond wire 100 in the second direction. Meanwhile, the second displacement member 31 can drive the movable plate 34, the fourth displacement member 35, and the two third grippers 33 to move together along the first direction, thereby achieving adjustment of the diamond wire 100 in the first direction.

[0057] For example, a connecting bar 37 is provided on the output end of the fourth displacement member 35, and both third grippers 33 are located on the connecting bar 37. The connecting bar 37 is guided to slide on the movable plate 34 by a slide rail and a slider.

[0058] For example, the first displacement member 22, the second displacement member 31, the fourth displacement member 35, the fifth displacement member 29, the sixth displacement member 67, and the seventh displacement member 68 can all be linear modules or cylinders. The first rotating member 26 and the second rotating member 51 can be motors.

[0059] Figure 11 This is a schematic diagram of the positioning column provided in an embodiment of the present invention, as shown below. Figure 11 As shown, the outer side of the end of the positioning post 36 facing away from the support platform 1 has an annular groove 361 for accommodating the diamond wire 100. The annular groove 361 is a conical groove to position the diamond wire 100 in the third direction.

[0060] In the above embodiment, the positioning column 36 can achieve precise positioning of the diamond wire 100 in a third direction through the conical groove during the pushing and moving process.

[0061] It is easy to understand that the gripper will shift the position of the diamond wire 100 during the process of releasing or re-clamping. However, through the positioning post 36 and the conical groove, precise positioning of the diamond wire 100 in the second and third directions can be achieved, ensuring that the appearance camera 32 can accurately photograph the diamond wire 100 during testing. Based on this, the position of the diamond wire 100 in the first direction is adjusted by the movement of the second displacement member 31, enabling photography at different positions.

[0062] For example, the support platform 1 is also provided with an adjustment module 321, which is used to fine-tune the appearance camera 32 in the Y and Z directions to ensure that the focus of the appearance camera 32 is exactly on the diamond wire 100 before the test. The appearance camera 32 is provided with a light source and a light source cover.

[0063] In one implementation of the present invention, the tensile testing assembly 4 further includes a first support 45 and a second support 46. The first support 45 is attached to the detection end of the force sensor 42 along a third direction. The first support 45 has a first motor 451. The output shaft of the first motor 451 is connected to a fourth gripper 44 to rotate the fourth gripper 44. The third displacement member 43 is used to drive the second support 46 to move in the direction away from the force sensor 42. The second support 46 is provided with a second motor 461. The output shaft of the first motor 451 is connected to another fourth gripper 44 to rotate the other fourth gripper 44.

[0064] In the above embodiment, the first support 45 and the second support 46 support the first motor 451 and the second motor 461 respectively, and the two motors can drive the fourth gripper 44 to rotate at a certain angle (e.g., 180°, that is, the fourth gripper 44 rotates half a turn), thereby increasing the friction between the gripper and the diamond wire 100 and ensuring the reliability of clamping the diamond wire 100 during the breakage detection process.

[0065] For example, the third displacement member 43 includes a motor, a lead screw, and a movable seat. The motor is fixed on the first bracket 41, the movable seat is slidably arranged on the first bracket 41, the output shaft of the motor is connected to the lead screw, the lead screw is threadedly engaged with the movable seat, and the lower fourth gripper 44 is fixedly connected to the movable seat.

[0066] The automatic diamond wire testing equipment provided by this invention integrates the feeding component 2 and multiple testing components to achieve automated feeding and simultaneous testing at multiple stations, thereby quickly obtaining various performance parameters of the diamond wire 100 and greatly improving testing efficiency.

[0067] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
