[0004] The above-mentioned testing equipments all perform single-item testing on the copper clad laminate to be tested, namely flatness testing and toughness testing, but the testing direction is single, and during the testing process, it is not convenient to perform multi-point testing on the copper clad laminate to be tested. After a single position test, it will be inconvenient to continue testing. The test data is single, which is not conducive to the comprehensive judgment of the performance of the entire copper clad laminate, and affects the accuracy of the test results. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a copper clad laminate detection device for a new energy vehicle charging pile.

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is: a copper clad plate detection device for a new energy vehicle charging pile, including a detection platform, and also including:

[0007] A clamping assembly, the clamping assembly includes a positioning clamp assembly and a conveying assembly, the positioning clamp assembly is used to clamp the edge of the stationary copper-clad laminate and position it on the detection table, and the conveying assembly is used to convey the copper-clad laminate to move after the positioning clamp cancels the clamping;

[0008] The detection component includes a detection roller and a driving component. During flatness detection, the driving component drives the detection roller to roll and contact the copper-clad laminate clamped by the positioning clamp component and positioned on the detection table to sense the flatness of the copper-clad laminate. During toughness detection, the detection roller acts as a pushing head, and the driving component drives the detection roller to squeeze a section of the copper-clad laminate that is transported out of the detection table through the conveying component, so that the copper-clad laminate is bent.

[0009] It should be understood that the entire testing process is divided into two steps. The first step is to place the copper clad laminate on the testing table, first clamp and position it with the positioning clamp assembly to maintain stability, and then roll the testing roller on the surface of the copper clad laminate to test the flatness of the surface, so as to achieve contact detection of the exposed surface of the copper clad laminate to be tested. The second step is to switch the working states of the positioning clamp assembly and the conveying assembly, cancel the clamping of the copper clad laminate by the positioning clamp assembly, switch the conveying assembly to convey the copper clad laminate, and after conveying the copper clad laminate for a specified distance, squeeze the copper clad laminate downward with the testing roller, so that a section leaving the testing table is squeezed and bent, so as to achieve toughness detection, and after testing a section, continue to convey the copper clad laminate, so that the part of the copper clad laminate that has not been tested for toughness is conveyed out of the testing table, and continue to perform toughness detection, thereby achieving toughness detection of multiple positions on the same copper clad laminate to be tested.

[0010] During the entire testing process, not only the flatness test of the same copper clad laminate is realized, but also the toughness test of the copper clad laminate is realized. During the flatness test, the exposed copper clad laminate surface to be tested is subjected to comprehensive rolling contact test. During the toughness test, the copper clad laminate is conveyed and adjusted to realize multi-position detection, so that multiple toughness tests can be performed on one copper clad laminate, which is conducive to comprehensive analysis of the results of multiple toughness tests, and further conducive to improving the accuracy of the toughness test results.

[0011] As an optional technical solution of the present invention, the driving component includes:

[0012] A support frame, the support frame includes a connecting frame and a connecting column, the two ends of the connecting frame are respectively rotatably connected to the two ends of the detection roller, the top of the connecting column is provided with an elastic member, a support sleeve is slidably sleeved on the surface of the connecting column, and a limiting ring for limiting the connection column from being separated from the support sleeve is also fixedly connected to the surface of the connecting column;

[0013] A movable frame, wherein the movable frame is driven to move by a threaded driving unit, and a first linear driving unit for adjusting the height position of the supporting sleeve is connected between the top end of the movable frame and the supporting sleeve;

[0014] A pressure detector is fixedly mounted on the support sleeve, and a detection end of the pressure detector contacts the top end of the elastic member to detect the pressure generated by the overall upward thrust of the detection roller and the elastic member on the pressure detector.

[0015] It should be understood that in the process of flatness detection of the copper clad laminate, the positioning clamp assembly positions and clamps the copper clad laminate placed on the surface of the detection table, and then drives the support sleeve to move downward through the first linear drive unit, and the support sleeve drives the support frame and the detection roller to move downward until they contact the copper clad laminate. At this time, the elastic part at the top of the connecting column on the support frame and the detection end of the pressure detector generate an extrusion force, and the first pressure value is detected by the pressure detector. The threaded drive unit then drives the moving frame to move, and the moving frame synchronously drives the first linear drive unit and the detection roller as a whole to move from one end of the copper clad laminate to the other end, so that the detection roller rolls and contacts the exposed surface of the copper clad laminate to be detected. If there is unevenness, when the copper clad laminate has a convex surface, the detection roller will be lifted up, so that the connecting column drives the elastic part to increase the extrusion pressure on the detection head of the pressure detector, and the second pressure value is measured. The second pressure value will increase relative to the first pressure value, indicating that the surface of the copper clad laminate is not flat.

[0016] After the flatness inspection of the copper clad laminate is completed, the copper clad laminate is transported out for a section through the conveying assembly, and then the inspection roller is moved to above the section where the copper clad laminate is transported out of the inspection table, and then the first linear drive unit continues to drive downward, so that the inspection head presses downward to squeeze the copper clad laminate until the copper clad laminate bends, and then the inspection roller is driven upward by the first linear drive unit to realize the toughness inspection of the copper clad laminate.

[0017] As a further optimized technical solution of the present invention, it also includes:

[0018] Two mobile clamping seats, which are symmetrically arranged and connected to the two ends of the detection platform through the second linear drive unit. The two mobile clamping seats are provided with accommodating grooves on the facing surfaces to accommodate the two ends of the copper clad plate;

[0019] Mounting slot group: a plurality of mounting slot groups are provided on the two movable clamping seats, and the mounting slot group includes a first mounting slot and a second mounting slot. The first mounting slot is used to install the positioning clamp assembly, and the second mounting slot is used to install the conveying assembly.

[0020] It should be understood that the two mobile clamping seats are first driven away from the middle position of the inspection table by the second linear drive unit, leaving enough shelf space for the staff to place the copper clad laminate, and then the copper clad laminate is prevented. The two mobile clamping seats are first driven close to each other by the linear drive unit to center the contact of the copper clad laminate, and then the mobile clamping seats are pulled away from the copper clad laminate by a slight distance to keep the edge of the copper clad laminate in the accommodating groove, and then the positioning clamp assembly is used to clamp and position it in preparation for flatness detection. After the flatness detection is completed, the clamping of the positioning clamp assembly is canceled, and the copper clad laminate is transported by the conveying assembly to move a section of the copper clad laminate out of the inspection table, and then the positioning clamp assembly is used to clamp and position it, and the detection roller is squeezed and pushed to prepare for toughness detection.

[0021] As an optional technical solution of the present invention, the two movable clamping seats are each provided with a plurality of mounting slot groups, and the positioning clamp assembly is correspondingly provided with a plurality of positioning clamp assemblies, the positioning clamp assembly includes

[0022] A clamping jaw, wherein the clamping jaw is slidably inserted into the first mounting groove;

[0023] The adjusting component is used to adjust the height positions of the plurality of clamping claws on the same movable clamping seat in the first mounting groove, so as to clamp or release the edge of the copper-clad board accommodated in the accommodating groove.

[0024] It should be understood that by providing a plurality of clamping claws on a movable clamping seat, after the copper-clad laminate moves a certain distance out of the inspection table, there are still clamping claws that can clamp the copper-clad laminate remaining on the inspection table. The specific clamping operation is as follows:

[0025] When the clamping jaws are adjusted to rise by the adjusting component, the clamping of the edge of the copper-clad board is cancelled, and when the clamping jaws are adjusted to lower the height by the adjusting component, the copper-clad board is contacted until it is clamped.

[0026] As an optional technical solution of the present invention, the adjustment component includes:

[0027] A plurality of inclined grooves, each of which is respectively provided on the side of each of the plurality of clamping jaws, wherein a linkage pin is slidably arranged in each of the inclined grooves, and ends of the linkage pins on each of the plurality of clamping jaws on the same movable clamping seat are fixedly connected to a driving frame;

[0028] The electric cylinder is fixedly mounted on the side wall of the mobile clamping seat, and the movable end is fixedly connected to the driving frame to realize the overall movement of the driving frame and the linkage pin, and the height of the clamping claw is adjusted by the linkage pin acting on the inclined slot.

[0029] It should be understood that when the height of the clamping jaws needs to be adjusted, the electric cylinder is started, the electric cylinder drives the driving frame to move, the driving frame synchronously drives the driving linkage pin to move, and the linkage pin moves in the inclined groove. The linkage pin acts on the inclined groove, so that the height of the clamping jaws changes, thereby realizing the synchronous adjustment of the height of multiple clamping jaws.

[0030] As a further optimized technical solution of the present invention, the conveying assembly is arranged in one-to-one correspondence with the multiple mounting groove groups on the mobile clamping seat, and the conveying assembly includes:

[0031] Two conveying rollers, the two conveying rollers are arranged in the second mounting groove and are located above and below the edge of the copper clad laminate;

[0032] Two limiting grooves, the two limiting grooves are arranged on the side walls of the second mounting groove, the two limiting grooves are both slidably connected with mounting seats, and the sides of the two mounting seats are respectively rotatably connected with the connecting shafts fixed on the sides of the two conveying rollers;

[0033] Two first motors, the two first motors are fixedly connected to the side walls of the two mounting seats, and the output ends are fixedly connected to the conveying rollers to provide power for the rotation of the conveying rollers;

[0034] The spacing adjustment component is used to adjust the conveyor rollers to move toward or away from each other, so as to achieve synchronous adjustment of the two conveyor rollers to move toward or away from the edge of the copper clad laminate.

[0035] It should be understood that conveying rollers are arranged above and below the copper clad laminate. When the flatness test is completed and the toughness test is required, the multiple clamps are synchronously raised through the spacing adjustment component to cancel the clamping of the copper clad laminate. Then the spacing adjustment component adjusts the two conveying rollers so that the two adjustment rollers move toward each other until they contact the copper clad laminate. Then the first motor is started and the first motor drives the conveying rollers to rotate. The two conveying rollers rotate to convey the clamped copper clad laminate a certain distance so that the copper clad laminate is a certain distance away from the inspection table. When the movement is completed, the two conveying rollers are adjusted to move away from each other through the spacing adjustment component. Then the height of the clamps is adjusted through the adjustment component to clamp and position the copper clad laminate that has completed the movement, so as to prepare for the subsequent toughness test.

[0036] As a further optimized technical solution of the present invention, the spacing adjustment component includes:

[0037] A rotating toothed disc, the rotating toothed disc is rotatably connected to the inner side wall of the second mounting groove, and two guide grooves distributed in a circular array are provided on the side surface, and the connecting shaft is slidably connected to the guide grooves, so that when the rotating toothed disc rotates in the first direction, the two guide grooves synchronously pull the two connecting shafts to move toward each other;

[0038] An intermediate gear is meshed with the bottom end of the rotating gear disc, and the bottom ends of the plurality of intermediate gears on the movable clamping seat are meshed with a driving rack, which passes through the movable clamping seat and is fixedly connected to the side wall of the driving frame.

[0039] It should be understood that there are three situations. In the first situation, when the copper-clad board just placed on the test table is adjusted to the center, the clamping positioning of the clamping jaws and the conveying state of the conveying roller of the conveying assembly must be cancelled. In the second situation, when the clamping jaws are positioned, the conveying assembly is not required. In the third situation, when the conveying roller is working, the clamping jaws positioning function is not required. Therefore, when switching the working states of the clamping jaws and the conveying assembly, the clamping jaws and the conveying rollers need to be adjusted separately, which is complicated to operate. The technical solution can solve the above problems, as follows:

[0040] Before centering the copper-clad laminate placed on the inspection table, the driving frame is driven by the electric cylinder, so that the driving frame drives the linkage pin and the driving rack to move. The linkage pin drives the clamping claw to keep a certain distance from the top surface of the copper-clad laminate through the inclined groove, drives the rack, and drives the rotating gear plate to rotate under the transmission of the intermediate gear. The connecting shaft is connected through the guide groove, and the two conveying rollers are also kept at a certain distance from the copper-clad laminate. The distance between the clamping claw and the conveying roller and the surface of the copper-clad laminate can be achieved directly by adjusting the electric cylinder drive;

[0041] When the clamping jaw needs to be positioned, the conveying assembly is not required to function. The electric cylinder is started, and the driving frame is pushed by the electric cylinder. The driving frame drives the linkage pin to move, and the linkage pin pushes the inclined slot, so that the clamping jaw moves downward until the clamping jaw clamps the copper-clad plate, and the clamping positioning is completed. During the movement of the driving frame, the driving frame synchronously drives the driving rack to move, and under the transmission of the intermediate gear, the transmission rotates the toothed disc, and the rotating toothed disc rotates in the second direction. The two guide grooves respectively push the connecting shaft to move synchronously in the opposite direction, so that the conveying roller is away from the copper-clad plate, realizing the automatic switching of the working states of the clamping jaw and the conveying roller, which is convenient and fast.

[0042] When the conveying roller needs to work, there is no need for the positioning function of the clamping claw. The electric cylinder is started, and the driving frame is pulled by the electric cylinder. The driving frame drives the linkage pin to move, and the linkage pin pushes the inclined slot, so that the clamping claw moves upward until the clamping claw is away from the copper-clad plate. In the process of moving the driving frame, the driving frame synchronously drives the driving rack to move, and the driving rack drives the rotating toothed disc through the intermediate gear. When the rotating toothed disc rotates in a first direction, the two guide grooves respectively pull the connecting shaft to move synchronously toward each other, so that the conveying roller approaches the copper-clad plate until it contacts the copper-clad plate. In one-step operation, the automatic switching of the working states of the clamping claw and the conveying roller can be realized, which is convenient and quick.

[0043] Therefore, when the three working states of the conveying assembly and the positioning clamp assembly need to be adjusted, the working states of the conveying assembly and the positioning clamp assembly can be adjusted synchronously through a one-step operation, and the automatic switching of the working states of the clamp and the conveying roller can be realized, which is convenient and quick.

[0044] As a further optimized technical solution of the present invention, it also includes:

[0045] A cam, the cam is rotatably connected to the side of the connecting column, and an operating handle for rotating the cam is fixedly connected to the surface thereof, and the cam includes a first distal end and a second distal end;

[0046] A positioning plate, the bottom surface of which has a damping gasket, the positioning plate is slidably plugged on the surface of the connection frame, and an elastic support member is connected between the positioning plate and the connection frame to achieve elastic support for the position of the positioning plate;

[0047] In the process of rotating the cam for rotation adjustment by operating the handle, the first distal end contacts the bottom surface of the support sleeve so that the limit ring on the connecting column is tightly pressed against the top surface of the support sleeve, and the second distal end contacts the top of the positioning plate to maintain the damping gasket on the bottom surface of the positioning plate in close contact with the detection roller.

[0048] It should be understood that when it is necessary to perform a flatness test on the copper-clad laminate, it is necessary to maintain a sliding freedom between the connecting column and the support sleeve. When the detection roller is pushed up by the raised portion of the copper-clad laminate surface, the connecting column can move in the support sleeve, thereby driving the elastic member to increase the extrusion of the detection head of the pressure detector. However, before performing a toughness test on the copper-clad laminate that has been moved out of the detection platform, it is necessary to position the detection head relative to the support sleeve to prevent the detection roller from generating a moving buffer relative to the support head during the process of pushing and extruding the copper-clad laminate, thereby affecting the stability of pushing and extruding the copper-clad laminate. Therefore, during the process of rotating the cam by the operating handle to adjust the rotation, the first distal end contacts the bottom surface of the support sleeve, so that the limit ring on the connecting column is pressed against the top surface of the support sleeve, thereby stabilizing the relative position relationship between the detection roller and the support sleeve, and then the first linear drive unit drives the support sleeve to move a specified distance, so that the extrusion effect on the copper-clad laminate can be stably achieved, and the toughness test can be achieved, and the detection roller can be driven downward by the first linear drive unit to keep the same distance, thereby avoiding deviation caused by sliding between the detection roller and the support sleeve;

[0049] When the first distal end of the rotating cam contacts the bottom surface of the supporting sleeve, the second distal end contacts the top of the positioning plate, maintaining the movable clamping seat on the bottom surface of the positioning plate in close contact with the detection roller, thereby realizing the positioning of the detection roller and avoiding the detection roller from rotating and rolling during the process of extruding the copper-clad laminate, which is beneficial to maintaining the stability of the detection roller during the process of extruding the copper-clad laminate.

[0050] As a further optimized technical solution of the present invention, a plug-in slot is provided at the second distal end of the cam, a locking pin is slidably inserted in the plug-in slot, a return spring is connected between the locking pin and the inner wall of the plug-in slot, and a card interface is provided at the top of the positioning plate.

[0051] It should be understood that by providing the card pin and the card interface, during the process in which the first distal end of the rotating cam contacts the bottom surface of the support sleeve, and the card pin contacts the top of the positioning plate along with the second distal end, the card pin is directly opposite to the card interface, and under the push of the reset spring, the card pin is inserted into the card interface to achieve card connection, maintain the stability of the cam state, and then simultaneously achieve the stability of the positioning of the detection roller and the relative position positioning of the connecting column and the support sleeve;

[0052] It should be noted that when the locking needs to be cancelled, it is only necessary to move the locking pin.

[0053] As a further optimized technical solution of the present invention, a rotating shaft is fixedly connected to the cam, and the rotating shaft is rotatably connected to the side of the connecting column. A torsion spring is sleeved on the rotating shaft, and both ends of the torsion spring are respectively clamped on the cam and the connecting column to support the cam.

[0054] It should be understood that by setting a torsion spring, when the cam does not need to perform a convex limit, the non-convex state is maintained stable under the action of the torsion spring to avoid interference with the detection process. After the convex limit is completed, the locking pin is docked with the card interface to achieve the locking connection, but the torsion spring always maintains a reset tendency force. When the locking pin is pushed to cancel the docking with the card interface, the cam is automatically driven to reset under the reset force of the torsion spring to restore the non-convex limit state.

[0055] Compared with the prior art, the present invention has the following beneficial effects:

[0056] The present invention realizes the flatness detection of the same copper clad laminate and the toughness detection of the copper clad laminate during the whole detection process. During the flatness detection process, the exposed copper clad laminate surface to be detected is subjected to comprehensive rolling contact detection. During the toughness detection, the copper clad laminate is conveyed and adjusted to realize multi-position detection, thereby realizing multiple toughness detections on one copper clad laminate, which is beneficial to comprehensive analysis of the results of multiple toughness detections, and further beneficial to improving the accuracy of the toughness detection results.

[0057] In the present invention, the electric cylinder drives the driving frame to move, the driving frame synchronously drives the driving linkage pin to move, and the linkage pin moves in the inclined groove. The linkage pin acts on the inclined groove, so that the height of the clamping jaws changes, thereby realizing synchronous adjustment of the heights of multiple clamping jaws.

[0058] The present invention, in order to adjust the copper clad laminate to adapt to the state required for detection, in the process of adjusting the three working states of the conveying component and the positioning clamp component, can realize synchronous adjustment of the working states of the conveying component and the positioning clamp component through a one-step operation, and can realize automatic switching of the working states of the clamp and the conveying roller, which is convenient and quick.

[0059] In the present invention, during the process that the first distal end of the rotating cam contacts the bottom surface of the supporting sleeve, the second distal end contacts the top of the positioning plate, maintaining the movable clamping seat on the bottom surface of the positioning plate in close contact with the detection roller, thereby realizing the positioning of the detection roller and avoiding the detection roller from rotating and rolling during the process of extruding the copper-clad laminate, which is beneficial to maintaining the stability of the detection roller during the process of extruding the copper-clad laminate.

DETAILED DESCRIPTION

[0072] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0073] like Figures 1 to 11 A copper-clad laminate detection device for a new energy vehicle charging pile shown includes a detection platform 1 and also includes:

[0074] The clamping assembly includes a positioning clamp assembly 3 and a conveying assembly 4. The positioning clamp assembly 3 is used to clamp the edge of the stationary copper-clad laminate 2 and position it on the surface of the inspection table 1. The conveying assembly 4 is used to convey the copper-clad laminate 2 to move after the positioning clamp cancels the clamping.

[0075] The detection component includes a detection roller 5 and a driving component. During the flatness detection, the driving component drives the detection roller 5 to roll and contact the copper clad laminate 2 clamped and positioned on the detection table 1 by the positioning clamp component 3 to sense the flatness of the copper clad laminate 2. During the toughness detection, the detection roller 5 acts as a pushing head, and the driving component drives the detection roller 5 to squeeze a section of the copper clad laminate 2 that is transported out of the detection table 1 through the conveying component 4, so that the copper clad laminate 2 bends.

[0076] It should be understood that the entire detection process is divided into two steps. The first step is to place the copper clad laminate 2 on the detection table 1, first clamp and position it through the positioning clamp assembly 3 to maintain stability, and then roll and move the detection roller 5 on the surface of the copper clad laminate 2 to detect the flatness of the surface of the copper clad laminate 2, so as to achieve contact detection of the exposed surface of the copper clad laminate 2 to be detected. The second step is to switch the working states of the positioning clamp assembly 3 and the conveying assembly 4, cancel the clamping of the copper clad laminate 2 by the positioning clamp assembly 3, switch the conveying assembly 4 to convey the copper clad laminate 2, and after conveying the copper clad laminate 2 for a specified distance, press the copper clad laminate 2 downward through the detection roller 5, so that a section leaving the detection table 1 is squeezed and bent to achieve toughness detection, and after a section is detected, the copper clad laminate 2 can be continuously conveyed, so that the part of the copper clad laminate 2 that has not been subjected to toughness detection is conveyed out of the detection table 1, and the toughness detection is continued, thereby achieving toughness detection of multiple positions of the same copper clad laminate 2 to be detected;

[0077] During the entire testing process, both the flatness test and the toughness test of the same copper clad laminate 2 are realized. During the flatness test, the exposed copper clad laminate 2 is subjected to a comprehensive rolling contact test on the test surface. During the toughness test, the copper clad laminate 2 is conveyed and adjusted to realize multi-position detection. Multiple toughness tests are performed on one copper clad laminate 2, which is beneficial to the comprehensive analysis of the results of multiple toughness tests, and further beneficial to the improvement of the accuracy of the toughness test results.

[0078] As an optional embodiment of the present invention, the driving component includes:

[0079] The support frame 6 includes a connecting frame 7 and a connecting column 8. The two ends of the connecting frame 7 are rotatably connected to the two ends of the detection roller 5 respectively. The top of the connecting column 8 is provided with an elastic member 9. A supporting sleeve 10 is slidably sleeved on the surface of the connecting column 8. A limiting ring 11 for limiting the connection column 8 from being separated from the supporting sleeve 10 is also fixedly connected to the surface of the connecting column 8;

[0080] A moving frame 12, the moving frame 12 is moved and driven by a threaded driving unit, and a first linear driving unit 13 for adjusting the height position of the supporting sleeve 10 is connected between the top of the moving frame 12 and the supporting sleeve 10;

[0081] The pressure detector 14 is fixedly mounted on the support sleeve 10 , and the detection end of the pressure detector 14 contacts the top end of the elastic member 9 to detect the pressure generated by the overall upward thrust of the detection roller 5 and the elastic member 9 on the pressure detector 14 .

[0082] Specifically, the threaded drive unit includes a support base 15, which is fixedly connected to the bottom of the detection table 1. One side of the bottom end of the support base 15 is slidably connected to the bottom end of the moving frame 12 through a slide rail. A threaded rod 16 is threadedly connected to the moving frame 12. A second motor 17 fixedly mounted on the support base 15 is provided at the end of the threaded rod 16. The output end of the second motor 17 is fixedly connected to the end of the threaded rod 16 to realize that the threaded rod 16 is driven to rotate by the second motor 17, and the thread of the threaded rod 16 drives the moving frame 12 to move.

[0083] It should be understood that in the process of flatness detection of the copper clad laminate 2, the positioning clamp assembly 3 positions and clamps the copper clad laminate 2 placed on the surface of the detection table 1, and then drives the support sleeve 10 to move downward through the first first linear drive unit 13, and the support sleeve 10 drives the support frame 6 and the detection roller 5 to move downward until they contact the upper copper clad laminate 2. At this time, the elastic member 9 at the top of the connecting column 8 on the support frame 6 and the detection end of the pressure detector 14 generate an extrusion force, and the first pressure value is detected by the pressure detector 14, and then the threaded drive unit The thread drives the movable frame 12 to move, and the movable frame 12 synchronously drives the first linear drive unit 13 and the detection roller 5 to move as a whole from one end of the copper clad laminate 2 to the other end, so that the detection roller 5 rolls and contacts the exposed surface of the copper clad laminate 2 to be detected. If there is unevenness, when the copper clad laminate 2 has a convex surface, the detection roller 5 will be lifted up, so that the connecting column 8 drives the elastic member 9 to increase the squeezing pressure on the detection head of the pressure detector 14, and a second pressure value is measured. The second pressure value will increase relative to the first pressure value, indicating that the surface of the copper clad laminate 2 is not flat.

[0084] After the flatness inspection of the copper clad laminate 2 is completed, the copper clad laminate 2 is transported out for a section through the conveying component 4, and then the inspection roller 5 is moved to above the section where the copper clad laminate 2 is transported out of the inspection platform 1, and then the first linear drive unit 13 continues to drive downward, so that the inspection head is pressed downward to squeeze the copper clad laminate 2 until the copper clad laminate 2 bends, and then the inspection roller 5 is driven upward by the first linear drive unit 13 to realize the toughness inspection of the copper clad laminate 2.

[0085] It should be specifically explained that the first linear drive unit 13 is specifically an electric cylinder, which is fixedly connected to the top of the moving frame 12 , and the end of the piston rod is fixedly connected to the side wall of the support sleeve 10 .

[0086] As a further optimized embodiment of the present invention, it also includes:

[0087] Two mobile clamping seats 18, the two mobile clamping seats 18 are symmetrically arranged, and are both connected to the two ends of the detection platform 1 through the second linear drive unit 26, and the two mobile clamping seats 18 are provided with accommodating grooves 1801 on the facing surfaces to accommodate the two ends of the copper clad plate 2;

[0088] Mounting slot group: a plurality of mounting slot groups are provided on the two movable clamping seats 18 , and the mounting slot groups include a first mounting slot 19 and a second mounting slot 20 . The first mounting slot 19 is used to mount the positioning clamp assembly 3 , and the second mounting slot 20 is used to mount the conveying assembly 4 .

[0089] It should be understood that the two mobile clamping seats 18 are first driven away from the middle position of the inspection table 1 by the second linear drive unit 26, leaving enough shelf space for the staff to place the copper clad laminate 2, and then the copper clad laminate 2 is placed. The two mobile clamping seats 18 are first driven close to each other by the linear drive unit to center the copper clad laminate 2, and then the mobile clamping seats 18 are pulled away from the copper clad laminate 2 by a slight distance to keep the edge of the copper clad laminate 2 in the accommodating groove 1801, and then the positioning clamp assembly 3 is used to clamp and position it to prepare for flatness detection. After the flatness detection is completed, the clamping of the positioning clamp assembly 3 is canceled, and the copper clad laminate 2 is transported by the conveying assembly 4 to move a section of the copper clad laminate 2 out of the inspection table 1, and then it is clamped and positioned by the positioning clamp assembly 3, and the inspection roller 5 is squeezed and pushed to prepare for toughness detection.

[0090] As an optional embodiment of the present invention, the two movable clamping seats 18 are each provided with a plurality of mounting slot groups, and the positioning clamp assembly 3 is correspondingly provided with a plurality of positioning clamp assemblies, and the positioning clamp assembly 3 includes:

[0091] The clamping jaw 301 is slidably inserted into the first mounting groove 19;

[0092] The adjustment component is used to adjust the height position of multiple clamping claws 301 on the same movable clamping seat 18 in the first installation groove 19, so as to clamp or release the edge of the copper clad board 2 accommodated in the accommodation groove 1801.

[0093] It should be understood that by providing a plurality of clamping jaws 301 on a movable clamping seat 18, after the copper-clad board 2 moves a certain distance out of the inspection table 1, there are still clamping jaws 301 that can clamp the copper-clad board 2 remaining on the inspection table 1. The specific clamping operation is as follows:

[0094] When the clamping jaws 301 are raised by adjusting the adjusting component, the clamping of the edge of the copper clad board 2 is cancelled, and when the height of the clamping jaws 301 is lowered by adjusting the adjusting component, the copper clad board 2 is contacted until it is clamped.

[0095] As an optional embodiment of the present invention, the adjustment component includes:

[0096] A plurality of inclined grooves 302, the plurality of inclined grooves 302 are respectively provided on the sides of the plurality of clamping jaws 301, a linkage pin 303 is slidably arranged in the inclined grooves 302, and the ends of the linkage pins 303 on the plurality of clamping jaws 301 on the same movable clamping seat 18 are fixedly connected to a driving frame 304;

[0097] The electric cylinder 305 is fixedly mounted on the side wall of the movable clamping seat 18, and the movable end is fixedly connected to the driving frame 304 to realize the overall movement of the driving frame 304 and the linkage pin 303, and the height of the clamping jaw 301 is adjusted by the linkage pin 303 acting on the inclined slot 302.

[0098] It should be understood that when the height of the clamping jaws 301 needs to be adjusted, the electric cylinder 305 is started, the electric cylinder 305 drives the driving frame 304 to move, the driving frame 304 synchronously drives the driving linkage pin 303 to move, and the linkage pin 303 moves in the inclined groove 302. The linkage pin 303 acts on the inclined groove 302, so that the height of the clamping jaws 301 changes, thereby realizing the synchronous adjustment of the height of multiple clamping jaws 301.

[0099] As a further optimized embodiment of the present invention, the conveying assembly 4 is arranged in one-to-one correspondence with the multiple mounting groove groups on the mobile clamping seat 18, and the conveying assembly 4 includes:

[0100] Two conveying rollers 401, the two conveying rollers 401 are arranged in the second mounting groove 20 and are located above and below the edge of the copper clad laminate 2;

[0101] Two limiting grooves 402, the two limiting grooves 402 are arranged on the side wall of the second mounting groove 20, the two limiting grooves 402 are both slidably connected with mounting seats 403, and the sides of the two mounting seats 403 are rotatably connected with the connecting shafts 404 fixed to the sides of the two conveying rollers 401 respectively;

[0102] Two first motors 405, the two first motors 405 are fixedly connected to the side walls of the two mounting seats 403, and the output ends are fixedly connected to the conveying roller 401 to provide power for the rotation of the conveying roller 401;

[0103] The spacing adjustment component is used to adjust the conveying rollers 401 to move toward or away from each other, so as to achieve synchronous adjustment of the two conveying rollers 401 to synchronously approach or move away from the edge of the copper-clad laminate 2.

[0104] It should be understood that conveying rollers 401 are provided above and below the copper clad laminate 2. When the flatness test is completed and the toughness test is required, the multiple clamps 301 are synchronously raised through the spacing adjustment component to cancel the clamping of the copper clad laminate 2. Then the spacing adjustment component adjusts the two conveying rollers 401 so that the two adjustment rollers move toward each other until they contact the copper clad laminate 2. Then the first motor 405 is started and the first motor 405 drives the conveying rollers 401 to rotate. The two conveying rollers 401 rotate to convey the copper clad laminate 2 that has been clamped a certain distance so that the copper clad laminate 2 is a certain distance away from the inspection table 1. When the movement is completed, the two conveying rollers 401 are adjusted to move away from each other through the spacing adjustment component. Then the height of the clamps 301 is adjusted through the adjustment component to clamp and position the copper clad laminate 2 that has completed the movement, so as to prepare for the subsequent toughness test.

[0105] As a further optimized embodiment of the present invention, the spacing adjustment component includes:

[0106] The rotating gear disc 21 is rotatably connected to the inner side wall of the second mounting groove 20, and two guide grooves 22 distributed in a circular array are provided on the side surface, and the connecting shaft 404 is slidably connected to the guide groove 22, so that when the rotating gear disc 21 rotates in the first direction, the two guide grooves 22 synchronously pull the two connecting shafts 404 to move toward each other;

[0107] The intermediate gear 33 is meshed with the bottom end of the rotating gear plate 21 , and the bottom ends of the multiple intermediate gears 33 on the mobile clamping seat 18 are meshed with the driving rack 23 , and the driving rack 23 passes through the mobile clamping seat 18 and is fixedly connected to the side wall of the driving frame 304 .

[0108] When it is necessary to explain in detail, a clearance groove for driving the rack 23 to move is provided at the bottom end of the movable clamping seat 18 .

[0109] It should be understood that there are three situations. In the first situation, when the copper-clad board 2 just placed on the test table 1 is centered, the clamping positioning of the clamp 301 is canceled, and the conveying state of the conveying roller 401 of the conveying assembly 4 is canceled. In the second situation, when the clamp 301 is positioned, the conveying assembly 4 is not required. In the third situation, when the conveying roller 401 is working, the positioning effect of the clamp 301 is not required. Therefore, when switching the working state of the clamp 301 and the conveying assembly 4, the clamp 301 and the conveying roller 401 need to be adjusted separately, which is complicated. This embodiment can solve the above problems, as follows:

[0110] Before the copper clad laminate 2 placed on the inspection table 1 is centered, the driving frame 304 is driven by the electric cylinder 305, so that the driving frame 304 drives the linkage pin 303 and the driving rack 23 to move, and the linkage pin 303 drives the clamping jaw 301 to keep a certain distance from the top surface of the copper clad laminate 2 through the inclined groove 302, drives the rack 23, and drives the rotating toothed disk 21 to rotate under the transmission of the intermediate gear 33, and connects the shaft 404 through the guide groove 22, so that the two conveying rollers 401 are kept at a certain distance from the copper clad laminate 2. Therefore, by adjusting the drive of the electric cylinder 305, it is achieved that the clamping jaw 301 is kept at a certain distance from the copper clad laminate 2, and the two conveying rollers 401 are also kept at a certain distance from the copper clad laminate 2.

[0111] When the clamping jaw 301 needs to be positioned, the conveying component 4 does not need to be used, and the electric cylinder 305 is started. The electric cylinder 305 pushes the driving frame 304, and the driving frame 304 drives the linkage pin 303 to move. The linkage pin 303 pushes the inclined slot 302, so that the clamping jaw 301 moves downward until the clamping jaw 301 clamps the copper clad plate 2, and the clamping positioning is completed. In the process of moving the driving frame 304, the driving frame 304 synchronously drives the driving rack 23 to move, and under the transmission of the intermediate gear 33, the transmission rotates the toothed disc 21. When the rotating toothed disc 21 rotates in the second direction b, the two guide grooves 22 respectively push the connecting shaft 404 to move synchronously in the opposite direction, so that the conveying roller 401 is away from the copper clad plate 2, and the automatic switching of the working state of the clamping jaw 301 and the conveying roller 401 is realized, which is convenient and fast.

[0112] When the conveying roller 401 needs to work, the positioning function of the clamping jaw 301 is not required, and the electric cylinder 305 is started. The driving frame 304 is pulled by the electric cylinder 305, and the driving frame 304 drives the linkage pin 303 to move. The linkage pin 303 pushes the inclined slot 302, so that the clamping jaw 301 moves upward until the clamping jaw 301 is away from the copper clad plate 2. In the process of the driving frame 304 moving, the driving frame 304 synchronously drives the driving rack 23 to move, and the driving rack 23 drives the rotating toothed disc 21 through the intermediate gear 33. When the rotating toothed disc 21 rotates in the first direction a, the two guide grooves 22 respectively pull the connecting shaft 404 to move synchronously toward each other, so that the conveying roller 401 approaches the copper clad plate 2 until it contacts the copper clad plate 2. In one step, the automatic switching of the working state of the clamping jaw 301 and the conveying roller 401 can be realized, which is convenient and quick.

[0113] Therefore, when the three working states of the conveying component 4 and the positioning clamp component 3 need to be adjusted, the working states of the conveying component 4 and the positioning clamp component 3 can be adjusted synchronously through a one-step operation, and the automatic switching of the working states of the clamp 301 and the conveying roller 401 can be realized, which is convenient and quick.

[0114] As a further optimized embodiment of the present invention, it also includes:

[0115] The cam 24 is rotatably connected to the side of the connecting column 8, and an operating handle 25 for rotating the cam 24 is fixedly connected to the surface thereof. The cam 24 includes a first distal end 2401 and a second distal end 2402;

[0116] A positioning plate 27, the bottom surface of which has a damping gasket, the positioning plate 27 is slidably plugged on the surface of the connecting frame 7, and an elastic support member 28 is connected between the positioning plate 27 and the connecting frame 7 to achieve elastic support for the position of the positioning plate 27;

[0117] In the process of rotating the cam 24 by operating the handle 25 to rotate and adjust, the first distal end 2401 contacts the bottom surface of the support sleeve 10, so that the limiting ring 11 on the connecting column 8 is tightly pressed against the top surface of the support sleeve 10, and the second distal end 2402 contacts the top of the positioning plate 27, maintaining the damping gasket on the bottom surface of the positioning plate 27 in close contact with the detection roller 5.

[0118] It should be understood that when it is necessary to perform a flatness test on the copper clad laminate 2, it is necessary to maintain a sliding freedom between the connecting column 8 and the support sleeve 10. When the detection roller 5 is pushed up by the raised portion on the surface of the copper clad laminate 2, the connecting column 8 can move in the support sleeve 10, thereby driving the elastic member 9 to increase the extrusion of the detection head of the pressure detector 14. However, before performing a toughness test on the copper clad laminate 2 that has been moved out of the detection platform 1, it is necessary to position the detection head relative to the support sleeve 10 to prevent the detection roller 5 from generating a movement buffer relative to the support head during the process of pushing and squeezing the copper clad laminate 2, thereby affecting the stability of pushing and squeezing the copper clad laminate 2. During the process of rotating the cam 24 by the operating handle 25, the first distal end 2401 contacts the bottom surface of the support sleeve 10, so that the limit ring 11 on the connecting column 8 is pressed against the top surface of the support sleeve 10, so as to stabilize the relative position relationship between the detection roller 5 and the support sleeve 10, and then drive the support sleeve 10 to move a specified distance by the first linear drive unit 13, so as to stably realize the extrusion effect on the copper clad laminate 2, realize toughness detection, and make the detection roller 5 be driven downward by the first linear drive unit 13 to keep consistent, so as to avoid deviation caused by sliding between the detection roller 5 and the support sleeve 10;

[0119] When the first distal end 2401 of the rotating cam 24 contacts the bottom surface of the support sleeve 10, the second distal end 2402 contacts the top of the positioning plate 27, maintaining the movable clamping seat 18 on the bottom surface of the positioning plate 27 in close contact with the detection roller 5, thereby realizing the positioning of the detection roller 5 and avoiding the detection roller 5 from rotating and rolling during the process of squeezing the copper clad laminate 2, which is beneficial to maintaining the stability of the detection roller 5 during the process of squeezing the copper clad laminate 2.

[0120] As a further optimized embodiment of the present invention, a plug-in slot is provided at the second distal end 2402 of the cam 24, a snap-in pin 29 is slidably inserted in the plug-in slot, a return spring is connected between the snap-in pin 29 and the inner wall of the plug-in slot, and a card interface 30 is provided at the top of the positioning plate 27.

[0121] It should be understood that by providing the engaging pin 29 and the engaging interface 30, in the process that the first distal end 2401 of the rotating cam 24 contacts the bottom surface of the support sleeve 10, and the engaging pin 29 contacts the top of the positioning plate 27 along with the second distal end 2402, at this time, the engaging pin 29 is directly opposite to the engaging interface 30, and under the push of the reset spring, the engaging pin 29 is inserted into the engaging interface 30 to achieve engaging, maintain the stability of the state of the cam 24, and then simultaneously achieve the stability of the positioning of the detection roller 5 and the relative positioning of the connecting column 8 and the support sleeve 10;

[0122] It should be noted that when the locking needs to be cancelled, it is only necessary to move the locking pin 29 .

[0123] As a further optimized embodiment of the present invention, a rotating shaft 31 is fixedly connected to the cam 24, and the rotating shaft 31 is rotatably connected to the side of the connecting column 8, and a torsion spring 32 is sleeved on the rotating shaft 31, and the two ends of the torsion spring 32 are respectively clamped on the cam 24 and the connecting column 8 to support the cam 24.

[0124] It should be understood that by providing the torsion spring 32, when the cam 24 does not need to perform a convex limit, the non-convex state is maintained stable under the action of the torsion spring 32 to avoid interference with the detection process. After the convex limit is completed, the locking pin 29 is docked with the card interface 30 to achieve the locking connection, but the torsion spring 32 always maintains a reset tendency force. When the locking pin 29 is moved to cancel the docking with the card interface 30, the cam 24 is automatically driven to reset under the reset force of the torsion spring 32 to restore the non-convex limit state.

[0125] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
