Description

Technical Field

[0001] The present application relates to the field of cable thickness detection, and in particular to a device for preparing a sample for detecting the thickness of a cable insulation layer. Background Art

[0002] At present, the use of cables is very extensive. A cable includes an inner core and an outer insulation layer. In order to enable the cable to resist tension, bending, and high temperature, etc., it is essential to ensure the thickness of the outer insulation layer of the cable. Therefore, after the cable is produced, it is necessary to measure the thickness of the outer insulation layer of the cable to determine whether the produced cable meets the use standards. For the detection of the outer insulation layer of the cable, it is necessary to first cut the cable into short segments of samples to be measured, and then select a measuring tool to detect the sliced sample to obtain the accurate insulation layer thickness. Therefore, the production of sliced samples of the cable is essential.

[0003] In the related art, the production of cable sliced samples is to first cut the same batch of cables into samples to be measured, remove the inner cores of the samples to be measured, and measure the outer diameter and inner diameter of the samples to be measured to obtain the thickness of the outer insulation layer.

[0004] Since the thickness of the inner cores of cables varies due to different types of cables, when using the above related technology to produce sliced samples, only sliced samples of cables of the same size can be produced. Summary of the Invention

[0005] In order to adapt to cables of different sizes and realize the production of sliced samples of cables of different sizes in the same batch, and improve the efficiency of subsequent detection of the cable cortex thickness, the present application provides a device for preparing a sample for detecting the thickness of a cable insulation layer.

[0006] A device for preparing a sample for detecting the thickness of a cable insulation layer provided by the present application adopts the following technical solutions:

[0007] A device for preparing a sample for detecting the thickness of a cable insulation layer includes a chassis, a feeding area, a detection component, a clamping component, a point pressing component, a cutting component, and a control component. The chassis includes a box body, an operation platform, and a connecting bracket. The operation platform and the connecting bracket are both arranged inside the box body, and the connecting bracket extends along the length direction of the box body. The connecting bracket is located above the operation platform. The feeding area and the detection component are both fixed to the operation platform. The clamping component is slidably connected to the operation platform. The cutting component is fixed to the connecting bracket;

[0008] The point pressing assembly includes a point pressing driving member and multiple groups of point pressing members. The multiple groups of point pressing members are arranged along the length direction of the box body, and the point pressing members are slidably connected to the connection bracket. The diameters of each group of point pressing members are different. The point pressing driving member is fixedly connected to the connection bracket. The point pressing driving member is arranged along the height direction of the box body and moves closer to or away from the point pressing members along the height direction of the box body;

[0009] The control assembly includes a detection control member, a clamping control member, a point pressing control member, and a cutting control member. The detection control member is used to control the detection assembly to detect the sample to be tested inside the feeding area, obtain the detection size of the sample to be tested, and send a first size signal. The clamping control member is used to receive the first size signal to control the feeding amount of the clamping assembly moving towards the clamped sample to be tested. The point pressing control member is used to receive the first size signal to control the point pressing member corresponding to the outer diameter size of the sample to be tested to move to directly below the point pressing driving member. The point pressing control member is also used to control the point pressing driving member to move towards the point pressing member.

[0010] By adopting the above technical solution, the detection control member obtains the outer diameter size of the sample to be tested and sends a first size signal, and uses this first size signal to control the feeding amount of the clamping assembly moving towards the clamped sample to be tested, thereby realizing precise fixation of the sample to be tested; the point pressing control member is used to receive the first size signal to control the point pressing assembly to select the point pressing member with the corresponding size, thereby realizing core removal of the sample to be tested, and being able to adapt to samples to be tested of different sizes, improving the efficiency of later detection of the cable cortex thickness.

[0011] Optionally, the clamping assembly includes:

[0012] A three-jaw chuck, which includes three movable jaws;

[0013] An abutting member, which is fixedly connected to one movable jaw of the three-jaw chuck away from the cutting assembly;

[0014] A fixed seat, which is arranged on the operation platform, and both the three-jaw chuck and the abutting member are slidably connected to the fixed seat;

[0015] A jaw driving member, the output shaft of which is connected to the three-jaw chuck, and the jaw driving member is used to drive the three movable jaws of the three-jaw chuck to all move towards the center of the fixed seat;

[0016] Wherein, when the clamping control member receives the first size signal, the clamping control member controls the three movable jaws of the three-jaw chuck to all move towards the sample to be tested clamped on the fixed seat by a feeding amount corresponding to the first size signal.

[0017] By adopting the above technical solution, when the clamping control member receives the first size signal, the three movable jaws of the three-jaw chuck move towards the center of the fixed seat by a size distance corresponding to the first size signal, thereby being able to fix the sample to be measured.

[0018] Optionally, the abutting member includes:

[0019] An abutting plate provided with an abutting surface on the abutting plate, and the abutting surface moves towards the side of the cutting assembly;

[0020] A fixing rod fixed to the abutting plate;

[0021] A cushion block fixed to a movable jaw of the three-jaw chuck away from the cutting assembly, and the fixing rod is slidably connected to the cushion block;

[0022] An elastic member provided on the fixing rod, and the elastic member is located between the abutting plate and the cushion block;

[0023] A limiting member threadedly connected to the fixing rod, and the limiting member is located on the side of the cushion block away from the elastic member;

[0024] Wherein, when a movable jaw of the three-jaw chuck drives the cushion block to move towards the cutting assembly, the cushion block will axially squeeze the elastic member along the fixing rod. When the jaw driving member stops driving the three-jaw chuck to move, the elastic member will drive the abutting plate to continue moving towards the cutting assembly.

[0025] By adopting the above technical solution, when the three-jaw chuck drives the cushion block to move towards the sample to be measured, the elastic member will be subjected to the same pressure. Then, when the three-jaw chuck moves a corresponding distance, the elastic member will make the abutting plate continue to move towards the sample to be measured until the limiting member on the fixing rod abuts against the cushion block, thereby abutting the part of the sample to be cut against the fixed seat. When the cutting assembly cuts the sample to be measured, the cut part can be left on the cutting assembly, improving the collection of the cut sample to be measured.

[0026] Optionally, the point pressing assembly further includes a point pressing platform and a point pressing moving member slidably connected to the point pressing platform. The point pressing platform is used to fix the point pressing member, and the point pressing platform is located below the point pressing driving member. The point pressing moving member is connected to the connecting bracket and is slidably connected to the point pressing platform;

[0027] Wherein, when the point pressing moving member drives the point pressing platform to move along the length direction of the box body, multiple groups of point pressing members will sequentially pass directly below the point pressing driving member.

[0028] By adopting the above technical solution, when the point pressing driving member moves towards the point pressing member, the point pressing member can push out the inner core wire of the sample to be measured from the sample to be measured, so that the outer cortex of the sample to be measured is separated from the inner core wire, further improving the efficiency of detecting the thickness of the subsequent cable cortex.

[0029] Optionally, the clamping assembly further includes:

[0030] A longitudinal linear module, which is arranged on the operation platform and fixed to the operation platform;

[0031] A transverse linear module, which is arranged on the longitudinal linear module, and the transverse linear module is slidably connected to the longitudinal linear module and is also slidably connected to the fixed seat;

[0032] Wherein, the transverse linear module is used to drive the support platform and the fixed seat to move along the length direction of the chassis, and the longitudinal linear module is used to drive the transverse linear module, the support platform and the fixed seat to move along the width direction of the chassis.

[0033] By adopting the above technical solution, the clamping assembly can move along the width direction of the chassis, so that the cutting assembly can complete the cutting of the sample to be measured on the clamping assembly. Similarly, the clamping assembly can be moved under the point pressing driving member to complete the removal of the inner core wire of the sample to be measured, thus simplifying the operations of core removal and cutting of the sample to be measured and further improving the production efficiency of the sample to be measured.

[0034] Optionally, the point pressing assembly further includes a height sensor, which is arranged on the connecting bracket, and the height sensor is arranged on the side of the point pressing platform facing the clamping assembly, and the height sensor is used to detect the distance between the top of the sample to be measured on the clamping assembly and the point pressing platform.

[0035] By adopting the above technical solution, by detecting the distance between the top of the sample to be measured and the point pressing platform through the height sensor, the distance of the point pressing driving member moving towards the point pressing member can be controlled, the moving distance of the point pressing driving member can be made controllable, and the core removal accuracy of the sample to be measured can be improved.

[0036] Optionally, it further includes a grasping assembly, which includes a moving member and a grasping member. The moving member is arranged in the chassis, the grasping member is slidably connected to the moving member, the grasping member is used to grasp the sample to be measured in the feeding area onto the detecting member, the grasping member is also used to grasp the sample to be measured after detection from the detecting member onto the clamping assembly, and the grasping member is also used to grasp the sample to be measured after removing the inner core wire into the waste collection box.

[0037] By adopting the above technical solution, the moving part can grab the sample to be tested in the loading area to the detecting part, so that the detecting part can complete the outer diameter dimension measurement of the sample to be tested, and thus the feeding amount of the clamping component can be controlled and the pressing component can be controlled to select the pressing part with the corresponding dimension.

[0038] Optionally, the loading area is provided with loading holes, and there are multiple groups of loading holes. Each group of loading holes is internally provided with a gravity sensor.

[0039] By adopting the above technical solution, the multiple groups of loading holes enable batch production of the samples to be tested, thereby improving the production efficiency of the samples to be tested.

[0040] Optionally, the clamping component further includes a waste collection box, the waste collection box is connected to the fixed seat, and the waste collection box is provided with a plurality of placement boxes.

[0041] By adopting the above technical solution, the waste collection box can be used to place the waste of the samples to be tested and the samples to be tested cut off, which is convenient for searching during subsequent detection.

[0042] Optionally, the cutting component includes:

[0043] A cutter;

[0044] A pushing member, the pushing member is located on the cutter, and a workpiece placement area is formed between the pushing member and the cutter;

[0045] A tool rest, the tool rest is fixed inside the machine case, and the pushing member is slidably connected to the tool rest.

[0046] By adopting the above technical solution, the cut sample to be tested is pushed from the workpiece placement area into the machine case through the abutting rod, which is convenient for collecting the sample to be tested.

[0047] In summary, the present application includes at least one of the following beneficial technical effects:

[0048] 1. The point pressure control part is used to receive the first size signal to control the point pressure component to select the point pressure part with the corresponding size, so as to realize core removal of the sample to be tested, and thus can adapt to samples to be tested of different sizes;

[0049] 2. The abutting plate, in cooperation with the elastic member, the fixed rod and the limiting member, abuts the part of the sample to be tested that needs to be cut on the fixed seat. When the cutting component cuts the sample to be tested, the cut-off part can be left on the cutting component, improving the collection of the cut sample to be tested;

[0050] 3. The clamping assembly can move along the width direction of the chassis, enabling the cutting assembly to cut the test sample on the clamping assembly. Similarly, the clamping assembly can be moved under the point-pressing driving part to remove the inner core wire of the test sample, thus simplifying the operations of core removal and cutting of the test sample and further improving the production efficiency of the test sample.

Detailed implementation manners

[0060] The following further elaborates on this application with reference to the accompanying drawings.

[0061] The embodiment of this application discloses a device for preparing a sample for detecting the thickness of a cable insulation layer. Refer to Figure 1 and Figure 2, including a chassis 10, a loading area 20, a detection component 30, a clamping component 40, a point-pressing component 50, a cutting component 60, and a control component 70. The chassis 10 includes a box body 11, an operation platform 12, and a connecting bracket 13. The operation platform 12 and the connecting bracket 13 are both arranged inside the box body 11, and the connecting bracket 13 extends along the length direction of the box body 11. The connecting bracket 13 is located above the operation platform 12. The operation platform 12 includes a loading platform 121 and a moving platform 122. The moving platform 122 is arranged side by side with the loading platform 121 inside the box body 11, and the loading platform 121 is fixed to the box body 11, while the moving platform 122 is slidably connected to the inside of the box body 11. The loading area 20 and the detection component 30 are both fixed to the loading platform 121, the clamping component 40 is fixed to the moving platform 122, the point-pressing component 50 and the cutting component 60 are both fixed to the connecting bracket 13, and there is no baffle below the point-pressing component 50 and the cutting component 60, which facilitates the movement of the clamping component 40 below the point-pressing component 50 and the cutting component 60. The control component 70 is arranged outside the box body 11.

[0062] Boundary: The length direction of the chassis 10 is the X-direction identifier in the figure, the width direction of the chassis 10 is the Y-direction identifier in the figure, and the height direction of the chassis 10 is the Z-direction identifier in the figure. The clamping component 40 and the chassis 10 can move along the X-direction and Y-direction of the chassis 10.

[0063] The chassis 10 further includes a door body 14 and pulleys 15. The pulleys 15 are rotatably connected to the lower end of the box body 11. There are multiple door bodies 14, and all the multiple door bodies 14 are rotatably connected to the box body 11. Specifically, the pulleys 15 can be selected according to specific circumstances, and universal wheels or fixed pulleys 15 can be selected, but not limited to this. Universal wheels can be selected in this embodiment. The door body 14 can be opened and closed relative to the box body 11. When the device needs to be repaired when not in use, the door body 14 is opened with the box body 11, which facilitates the staff to repair the internal devices, and further improves the service life of the device.

[0064] Refer to Figure 2 and Figure 3 , the loading area 20 includes a loading hole 21, a loading rack 22, and a gravity sensor. The loading rack 22 is fixed to the operation platform 12 and is arranged along the X-direction of the box body 11. Multiple groups of loading holes 21 are opened on the loading rack 22, and a gravity sensor is provided at the bottom of each group of loading holes 21.

[0065] The detection component 30 includes a placement station 31, a laser detection piece 32, and a detection table 33. The detection table 33 is fixed to the operation platform 12. A placement groove is opened on the detection table 33, and the placement groove forms the placement station 31. The laser detection piece 32 is fixed to the detection table 33.

[0066] It should be noted here that the laser detection component 32 in this embodiment is a laser thickness gauge, and includes two opposed laser heads. The two opposed laser heads are relatively arranged on the side wall of the placement groove. When the sample to be measured is placed vertically on the placement station 31, the two relatively arranged laser heads detect the outer diameter thickness of the slicing station. This embodiment only uses this laser thickness gauge and does not change its internal structure. Therefore, regarding the internal structure of the laser thickness gauge and the principle of how to detect, no more explanations will be given here.

[0067] Referring to Figure 3 and Figure 4 , the clamping assembly 40 includes a three-jaw chuck 41, an abutting member 42, a fixed seat 43, and a jaw driving member 44. The three-jaw chuck 41 includes three movable jaws 411. The abutting member 42 is fixed to one movable jaw 411 of the three-jaw chuck 41 away from the cutting assembly 60. The fixed seat 43 is arranged on the operation platform 12, and both the three-jaw chuck 41 and the abutting member 42 are slidably connected to the fixed seat 43. The output shaft of the jaw driving member 44 is connected to the three-jaw chuck 41, and the jaw driving member 44 is used to drive the three movable jaws 411 of the three-jaw chuck 41 to move towards the center of the fixed seat 43. Among them, when the clamping control member receives the first size signal, the clamping control member controls the three movable jaws 411 of the three-jaw chuck 41 to move towards the sample to be measured clamped on the fixed seat 43 by a feed amount corresponding to the first size signal.

[0068] This application only uses the three-jaw chuck 41 to fix the sample to be measured and does not change its internal structure. Therefore, no more explanations will be given here about its specific internal structure. The specific type of the three-jaw chuck 41 is selected according to needs. This application selects a three-jaw, and adopts a pneumatic three-jaw chuck 41. When the control assembly 70 receives the first size signal, it will start the jaw driving member 44 to make the three movable jaws 411 move a corresponding distance towards the fixed seat 43, thereby realizing the fixation of the sample to be measured.

[0069] The abutting member 42 includes an abutting plate 421, a fixed rod 422, a cushion block 423, an elastic member 424, and a limiting member 425. The abutting plate 421 is provided with an abutting surface, and the abutting surface moves towards the side of the cutting assembly 60. One end of the fixed rod 422 is fixed to the abutting plate 421, and the other end passes through the cushion block 423 and is connected to the limiting member 425. The cushion block 423 is fixed to one movable jaw 411 of the three-jaw chuck 41 away from the cutting assembly 60, and the fixed rod 422 is slidably connected to the cushion block 423. The elastic member 424 is arranged on the fixed rod 422, and the elastic member 424 is located between the abutting plate 421 and the cushion block 423. The limiting member 425 is threadedly connected to the fixed rod 422, and the limiting member 425 is located on the side of the cushion block 423 away from the elastic member 424.

[0070] Among them, when a movable claw 411 of the three-jaw chuck 41 drives the pad 423 to move toward the cutting assembly 60, the pad 423 will squeeze the elastic member 424 along the axial direction of the fixed rod 422. When the claw driving member 44 stops driving the three-jaw chuck 41 to move, the elastic member 424 will drive the abutment plate 421 to continue moving toward the cutting assembly 60.

[0071] The waste collection box 47 is provided with a plurality of placement boxes 471 , and the waste collection box 47 and the clamping assembly 40 are both slidably connected to the operating platform 12 .

[0072] It should be noted that, in this embodiment, the elastic member 424 is a spring, the stopper 425 is a nut, and the stopper 425 is threadedly connected to the fixed rod 422. In the initial state of the elastic member 424, one end of the elastic member 424 abuts against the abutment plate 421, and the other end abuts against the cushion block 423, and the cushion block 423 and the stopper 425 abut against each other. When the three movable claws 411 approach the center of the fixed seat 43, the cushion block 423 will be driven to move axially along the fixed rod 422, and then the cushion block 423 compresses the elastic member 424. At this time, the elastic member 424 will push the abutment plate 421 to move axially along the fixed rod 422 due to the elastic force, until the fixed rod 422 drives the stopper 425 to abut against the cushion block 423 again. At this time, the moving direction of the abutment plate 421 is equal to the moving direction and distance of the cushion block 423.

When the point pressing platform 53 slides with the two groups of point pressing slide rails 544, the point pressing platform 53 drives multiple groups of point pressing members 52 to pass sequentially under the point pressing driving member 51. When the point pressing driving member 51 is started, the output shaft of the motor will move correspondingly along its output shaft towards one of the point pressing members 52 on the point pressing platform 53 and abut against the inner layer wire core of the sample to be measured located below the point pressing member 52, so that the inner layer wire core is pushed outwards. The distance that the inner layer wire core is pushed out can be adjusted according to actual needs. The distance that the inner layer wire core needs to be pushed out and the distance detected by the height sensor 55 are added together as the distance for the point pressing driving member 51 to move downwards.

[0089] It should be noted here that the vertical driving member 644 is a motor, and the tool rest 63 is slidably connected to the cutting and grasping bracket. When the vertical driving member 644 is started, the vertical lead screw 643 rotates to drive the vertical slider 642 to slide along the axial direction of the vertical lead screw 643, and then the tool rest 63 drives the tool 61 and the abutting member 42 to move along the Z direction of the box body 11.

[0090] The control assembly 70 includes a detection control member, a clamping control member, a point pressing control member, and a cutting control member. The detection control member is used to control the detection assembly 30 to detect the test sample inside the loading area 20, obtain the detection size of the test sample, and send a first size signal. The clamping control member is used to receive the first size signal to control the feed amount of the clamping assembly 40 moving towards the clamped test sample. The point pressing control member is used to receive the first size signal to control the point pressing member 52 corresponding to the outer diameter size of the test sample to move to directly below the point pressing driving member 51. The point pressing control member is also used to control the point pressing driving member 51 to move towards the point pressing member 52.

[0091] Refer to Figure 3 , and further includes a grasping assembly 80. The grasping assembly 80 includes a moving member and a grasping member 82. The moving member is arranged inside the chassis 10. The grasping member 82 is slidably connected to the moving member. The grasping member 82 is used to grasp the test sample in the loading area 20 onto the detection member, and the grasping member 82 is also used to grasp the test sample after detection from the detection member onto the clamping assembly 40. The grasping member 82 is also used to grasp the test sample after removing the inner core wire into the waste collection box 47.

[0092] The moving member includes a rotating lead screw 811, a moving slider 812, and a moving motor 813.

[0093] The grasping member 82 includes a support arm 821 and a gripper 822. The support arm 821 is fixed to the moving slider 812, and the gripper 822 is fixed to the support arm 821. When the moving motor 813 is started, the rotating lead screw 811 is rotated to drive the moving slider to move along the X direction of the box body 11, so that the gripper 822 grasps the sample to be tested in the feeding area 20 onto the detection assembly 30, grasps the sample to be tested after detection from the detection assembly 30 onto the clamping assembly 40, and grasps the sample to be tested after removing the inner core wire into the waste collection box 47.

[0094] It should be noted here that the grasping member 82, the feeding area 20, and the detection assembly 30 are in the same vertical plane, and when the moving direction of the grasping member 82 moves along the X direction of the box body 11, it passes through the feeding area 20 and the detection assembly 30.

[0095] The implementation principle of the cable insulation layer thickness detection sample preparation device in the embodiment of the present application is as follows: When a sample to be tested needs to be made for a cable, first place the sample to be tested that needs to be processed in a plurality of feeding holes 21. The moving motor 813 drives the gripper 822 to move to the corresponding position of the feeding hole 21 and grasp the sample to be tested at this position onto the placement station 31. The laser detection member 32 detects the outer diameter of the sample to be tested, and the detection control member receives the outer diameter of the sample to be tested and issues a first size signal.

[0096] Then, control the moving motor 813 to start to drive the gripper 822 to grasp the sample to be tested on the placement station 31 onto the fixed seat 43. At this time, receive the first size signal to control the start of the jaw driving member 44, so that the movable jaw 411 moves towards the center of the fixed seat 43 to fix the sample to be tested located on the fixed seat 43.

[0097] Start the longitudinal driving member 464 and the transverse driving member 454, so that the fixed seat 43 moves to directly below the point pressing driving member 51. At this time, the point pressing control member receives the first size signal to control the movement of the point pressing platform 53, so that the point pressing member 52 corresponding to the size of the sample to be tested is in the same vertical plane as the sample to be tested on the fixed seat 43. Start the point pressing driving member 51, so that the output shaft of the point pressing driving member 51 moves towards the point pressing platform 53, so that the inner core wire of the sample to be tested moves along the axial direction of the sample to be tested and towards the Z direction.

[0098] When the inner core wire at the upper end of the sample to be tested on the fixing base 43 has been removed, the horizontal linear module 45 and the vertical linear module 46 drive the three-jaw chuck 41, the abutting member 42, the fixing base 43 and the waste collection box 47 to move along the X direction and the Y direction to below the cutting assembly 60.

[0099] Control the start of the vertical driving member 644 so that the cutting tool 61 and the sample to be tested that needs to be cut on the fixing base 43 are on the same horizontal plane. Then start the horizontal linear module 45 so that the abutting member 42 moves towards the cutting tool 61, and then the cutting tool 61 cuts off the section of the sample to be tested that the abutting member 42 abuts against, and the cut-off is a sliced sample, which is left in the workpiece placement area.

[0100] Drive the pushing baffle 623 through the push rod 622 to push the sliced sample so that it falls on the fixing base 43 so that the grasping member 82 can grasp it into the placement box 471.

[0101] Finally, the three-jaw chuck 41 resets so that the grasping member 82 grasps the remaining sample to be tested into the placement box 471 where the sliced sample of the sample to be tested is located.

[0102] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
