Description

Technical Field

[0001] The present invention relates to the technical field of tensile strength detection of plates, and specifically to a device and a detection process for detecting the bonding strength of metal composite plates. Background Art

[0002] Metal composite plates refer to plates with another layer of metal covered on one layer of metal, which can achieve the effect of saving resources and reducing costs without reducing the use effects such as anti-corrosion performance and mechanical strength. At present, metal composite plates have been widely used in industrial fields such as petroleum, chemical industry, pharmacy, salt production, alkali production, water treatment, and food. When metal composite plates are applied, they will be bonded and fixed at a specified position. However, the bonding strength of metal composite plates is related to the use effect of metal composite plates. In the prior art, the method of manual pulling test is mostly used for testing. However, this testing method cannot obtain accurate anti-tensile bonding strength values. Therefore, a supporting tensile detection device is needed to detect the bonding strength of metal composite plates.

[0003] According to the Chinese patent with the publication number CN113432984A, a tensile test device and a tensile test method are disclosed. The object to be tested is placed on the workbench of the base. Through the movement of the walking structure, the force measuring mechanism is moved above the object to be tested. The pressing component presses and fixes the object to be tested. The tensile component is fixed to the components on the object to be tested. The tensile component applies a tensile force. The object to be tested will not move under the pressing of the pressing component. In this way, under the combined action of the action force and the reaction force, the action force that can be applied to the object to be tested can be measured. When the above technical solution is used, the movement of the walking structure drives the base and the force measuring mechanism to move. For the movable force measuring mechanism, it is impossible to provide stable isolation protection for the movable tensile detection position. Therefore, we propose a device and a detection process for detecting the bonding strength of metal composite plates. Summary of the Invention

[0014] A metal composite plate bonding strength testing process includes the following testing steps: Step 1: Lay the metal composite plate on the test piece, and perform negative pressure adsorption on the metal composite plate test piece through a vacuum suction cup fixture; Step 2: The linear slider drives the traveling frame to move along the linear guide rail, so that the vacuum suction cup hanger is aligned with and absorbs the metal composite plate to be tested; Step 3: The traction rope of the traction mechanism drives the horizontally placed support mechanism to be vertically unfolded, and the two groups of support mechanisms adjust the unfolding position according to the moving position of the traveling frame, so that the two groups of protective curtains cover both sides of the traveling frame, which is convenient for personnel to observe safely; Step 4: Perform tensile testing of the bonding strength of the metal composite plate bonded to the specimen with the assistance of a vacuum suction cup fixture and a vacuum suction cup hanger.

At this time, the two sets of support frames will open the transparent protective curtains and cover the two sides of the traveling frame. When the traveling frame moves to one side of the vacuum suction cup fixture to perform bonding strength detection of different positions of the metal composite plate, the two sets of support mechanisms will vertically abut the nearest side according to the position of the traveling frame, so that the protective curtains opened on the nearest side can protect the tensile detection position of the vacuum suction cup hanger, ensuring that no matter which side of the vacuum suction cup fixture the traveling frame moves to, the tensile detection of the position on that side of the traveling frame can be stably isolated and protected; 2.

When the rotating double-shaft motor drives two sets of support mechanisms to vertically unfold in sequence through a rotating cylinder, the first set of support mechanisms completes vertical placement while the second set of support mechanisms is not yet vertically placed.

Moreover, the anti-slip protrusions on the outer wall of the winding wheel will be squeezed and clamped into the groove on one side of the baffle. Therefore, the continuously rotating cylinder will drive the driving ring and the winding wheel of the first set to rotate relative to each other. At the same time, the winding wheel of the second set can continue to pull the support frame of the second set of support mechanisms through the traction rope. Furthermore, when the two sets of support mechanisms are vertically unfolded in sequence, the protective curtain can be fully unfolded. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-8 , the present invention provides a technical solution: a device for detecting the bonding strength of metal composite plates, including a vacuum suction cup fixture 1 for negatively adsorbing and carrying the metal composite plates and a walking frame 4 walking above the vacuum suction cup fixture 1. Linear guide rails 2 are installed on both side edges of the vacuum suction cup fixture 1, and a linear slider 3 for horizontal movement is connected to the top of the linear guide rails 2. The walking frame 4 is installed on the upper side of the linear slider 3, and a vacuum suction cup sling 5 for pulling the plate to be tested is arranged below the walking frame 4. The cooperation of the linear guide rails 2 and the linear slider 3 drives the walking frame 4 to move on the vacuum suction cup fixture 1, which is convenient for the vacuum suction cup sling 5 to perform tensile detection of the bonding strength at different positions of the metal composite plate, and is convenient for detecting the bonding strength of different positions of the metal composite plate and the specimen; Storage chambers 101 are provided inside the two sides of the vacuum suction cup fixture 1. The inner wall of the storage chamber 101 is fixed with a guide rod 103 and a return spring 102 sleeved on the outside of the guide rod 103 through a reserved opening. A support mechanism 6 is provided in the storage chamber 101. The support mechanism 6 includes a sliding sleeve 601 sliding with the guide rod 103. The upper side of the sliding sleeve 601 is fixed with brackets 602 arranged in sequence from high to low. A support frame 603 is rotatably connected to the bracket 602. A linkage arm 604 is movably connected between two adjacent support frames 603. The hinge center connection line of the two adjacent brackets 602 is parallel to the linkage arm 604. The outer side of the support frame 603 is connected with a protective curtain 8 for safe observation of tensile testing. A traction mechanism 7 for controlling the folding or unfolding of the support mechanism 6 is provided on the top of the traveling frame 4. The traction mechanism 7 includes a double-axis motor 701 installed on the top of the traveling frame 4. A rotating drum 702 is installed on the two output shafts of the double-axis motor 701. A driving ring 703 is sleeved on the outer side of the rotating drum 702. A reel 706 for winding a traction rope 708 is sleeved on the outer side of the driving ring 703. One end of the traction rope 708 is fixed to the support frame 603 closest to the traveling frame 4. Limiting rods 9 for opening the protective curtain 8 are installed at both ends of the vacuum suction cup fixture 1. A sensing strip 104 is fixed to the outer wall of the vacuum suction cup fixture 1 close to the storage chamber 101, and a support 605 is fixed to the end of the support frame 603 closest to the walking frame 4. A proximity switch 606 is installed at one end of the support 605, and the proximity switch 606 adopts an inductive metal proximity sensor.

[0020] During the specific implementation, the long strip of metal composite plate is bonded and fixed on the specimen, and the long strip of metal composite plate specimen is negatively adsorbed by the vacuum suction cup fixture 1, and then the linear guide rail 2 and the linear slider 3 cooperate to drive the traveling frame 4 to move linearly, so that the traveling frame 4 drives the vacuum suction cup hanger 5 to move to the specified position, and then the lifting motor 401 is started to drive the screw rod 402 to rotate forward, and the screw rod 402 drives the crossbeam 403 and the vacuum suction cup hanger 5 to move downward through the forward thread transmission, thereby driving the suction cup 506 of the vacuum suction cup hanger 5 to adsorb the metal composite plate on the upper layer of the specimen, and when the lifting motor 401 is started to drive the screw rod 402 to reverse, the screw rod 402 drives the crossbeam 403 and the vacuum suction cup hanger 5 to move upward through the reverse thread transmission, so that the bonding strength of the metal composite plate can be tensile tested; When the metal composite plate is subjected to tensile testing of the bonding strength, the two-axis motor 701 of the traction mechanism 7 is started to rotate forward to drive the two rotating drums 702 to rotate forward, so that the rotating drum 702 can drive the driving ring 703 to rotate, so that the driving ring 703 presses against the magnetic teeth 707 of the winding wheel 706 through the slot 705, so that the winding wheel 706 follows the rotation and drives the clockwise and counterclockwise winding traction ropes 708 to be tightened. At this time, the traction ropes 708 will pull the uppermost support frame 603 in the storage chamber 101, so that the support frame 603 03 The bracket 602 on the top of the sliding sleeve 601 rotates from a horizontal position to a vertical position. Since a linkage arm 604 is connected between two adjacent support frames 603, when one of the support frames 603 rotates and unfolds, the traction of the linkage arm 604 will cause the other support frames 603 to complete the rotation and unfolding together. At this time, the support frames 603 on both sides of the traveling frame 4 will open the transparent protective curtain 8 and cover both sides of the traveling frame 4. Therefore, the opened protective curtain 8 can isolate and protect the metal composite plate during the bonding strength tensile test process; When the traveling frame 4 moves toward one side of the vacuum suction cup fixture 1, the traveling frame 4 will move toward the direction of one of the groups of supporting mechanisms 6. Therefore, when the supporting mechanism 6 close to the traveling frame 4 rotates and unfolds, the supporting frame 603 closest to the traveling frame 4 will first tilt against the side edge of the top of the traveling frame 4 before the rotation reaches the vertical position. At this time, the rotating drum 702 that continues to rotate will continue to pull the traction rope 708 through the winding wheel 706, so that the traction rope 708 will drive the supporting frame 603 closest to the traveling frame 4 to flip, so that the supporting frame 603 drives the sliding sleeve 601 at the bottom to move along the guide rod 103 and stretch the reset spring 102. When the supporting frame 603 of this group of supporting mechanisms 6 drives the proximity switch 603 at one end of the support 605 When the support mechanism 6 on the other side of the traveling frame 4 is turned over to be vertically unfolded, the support frame 603 closest to the traveling frame 4 will not abut against the top side edge of the traveling frame 4. When the proximity switch 606 on the other side of the traveling frame 4 also abuts against the proximity sensing bar 104, the proximity switches 606 on the two groups of support mechanisms 6 will transmit the sensing signal to the external PLC controller, so that the PLC controller controls the dual-axis motor 701 to stop rotating. Therefore, when the traveling frame 4 changes its position while walking on the linear guide rail 2 and detects different positions of the metal composite plate through the vacuum suction cup hanger 5, the two sets of supporting mechanisms 6 will vertically abut on the nearest side according to the position of the traveling frame 4, so that the protective curtain 8 opened on the nearest side can provide stable isolation and protection for the tensile detection position of the vacuum suction cup hanger 5.

[0021] See alsoFigures 7-12 The driving rings 703 are symmetrically arranged on the rotating drum 702, and a sliding cavity 704 is annularly formed on the outer side of the driving ring 703. One side wall of the sliding cavity 704 is provided with clamping grooves 705 at equal angles. One side of the middle part of the winding wheel 706 is fixed with an inner ring that rotates with the sliding cavity 704, and one side of the inner ring is fixed with magnetic clamping teeth 707 that match the tooth grooves of the clamping grooves 705 at equal angles. The clamping grooves 705 are in a "V" - shaped structure, and the magnetic clamping teeth 707 are clamped with the clamping grooves 705 on the driving ring 703 through magnetic attraction. One of the winding wheels 706 on the same group of rotating drums 702 winds the towing rope 708 clockwise, and the other winding wheel 706 on the same group of rotating drums 702 winds the towing rope 708 counter - clockwise. The end of the towing rope 708 wound clockwise is connected to the support frame 603 on one side of the walking frame 4, and the end of the towing rope 708 wound counter - clockwise is connected to the support frame 603 on the other side of the walking frame 4. Therefore, the rotating drum 702 can drive the two groups of support mechanisms 6 to unfold or fold respectively through the two groups of towing ropes 708 wound clockwise and counter - clockwise. A baffle 710 installed on the top surface of the walking frame 4 is sleeved outside the rotating drum 702. One side of the baffle 710 is provided with grooves 711 at equal angles. Anti - slip protrusions 709 are fixed on the surface of the winding wheel 706 far from the driving ring 703. The distance between the anti - slip protrusions 709 and the grooves 711 matches the depth of the clamping grooves 705. A anti - detachment rod is vertically fixed on the surface of the baffle 710 near the lower side of the winding wheel 706, and the anti - detachment rod is used to prevent the towing rope 708 from detaching from the winding wheel 706.

[0022] During specific implementation, when the rotating dual-axis motor 701 drives the two sets of support mechanisms 6 to be vertically deployed in a sequential manner through the two sets of rotating cylinders 702, when the first set of support mechanism 6 is vertically placed while the second set of support mechanism 6 is not vertically placed, the continuously rotating dual-axis motor 701 cannot traction the support frame 603 of the first set of support mechanism 6 through the first set of winding wheels 706 and traction ropes 708 again. At this time, the continuously rotating dual-axis motor 701 can traction the support frame 603 of the second set of support mechanism 6 to produce a flip through the second set of winding wheels 706 and traction ropes 708; during this process, when the first set of drive rings 703 rotate, they will squeeze the magnetic teeth 707 on the side of the winding wheel 706 through the side wall of the "V"-shaped card slot 705, separating the magnetic teeth 707 from the card slot 705, and the magnetic teeth 707 will move along the drive ring 703 into the sliding cavity 704. At this time, the anti-slip protrusions 709 on the outer wall of the winding wheel 706 will be squeezed and snapped into the groove 711 on one side of the baffle 710. Therefore, the continuously rotating cylinder 702 will drive the first set of drive rings 703 and winding wheels 706 to rotate relatively, and through the engagement of the anti-slip protrusions 709 and the grooves 711, it can prevent the winding wheel 706 from reversing and causing the traction rope 708 to loosen and reverse. Furthermore, when the first set of winding wheels 706 remains stationary, the second set of rotating drive rings 703 can still traction the support frame 603 of the second set of support mechanism 6 through the second set of winding wheels 706 and traction ropes 708; When controlling the dual-axis motor 701 to drive the rotating cylinder 702 to stop rotating, the magnetic teeth 707 and the card slot 705 of the drive ring 703 are magnetically attracted to facilitate the combined clamping of the drive ring 703 and the winding wheel 706; when the dual-axis motor 701 drives the rotating cylinder 702 to reverse, the two sets of winding wheels 706 can unwind the traction ropes 708 to horizontally fold and place the two sets of support mechanisms 6, facilitating the opening of the protective curtain 8.

[0023] Please refer to Figures 1-4 and Figure 13 , lifting motors 401 are installed at both ends of the upper side of the walking frame 4. The output end of the lifting motor 401 is connected to a lead screw 402, and a cross beam 403 is threadedly connected to the outside of the lead screw 402. A vacuum suction cup lifting device 5 for traction of the to-be-tested plate is arranged in the middle of the cross beam 403; A regulating groove 404 is formed in the middle of the cross beam 403. A moving block 501 is slidably connected inside the regulating groove 404. One end of the moving block 501 is threadedly connected with a fastening pin 502 for pressing against the side wall of the cross beam 403. A tension sensor 503 is installed on the lower side of the moving block 501. A fixing plate 504 is installed on the lower side of the tension sensor 503. The tension sensor 503 adopts a weighing sensor with the model JLBS-1; A C-shaped steel 505 is fixedly connected below the fixing plate 504. A suction cup 506 for adsorbing the surface of the metal composite plate is installed on the C-shaped steel 505. The suction cup 506 adopts a vacuum suction cup with the model ZPT.

[0024] During specific implementation, the position of the moving block 501 in the regulating groove 404 is adjusted according to the positions of the metal composite plate and the test piece on the vacuum suction cup fixture 1, and then the fastening pin 502 is rotated to press against the side wall of the cross beam 403, so that the suction cup 506 can be aligned with the surface of the metal composite plate, facilitating the adjustment of the position of the vacuum suction cup lifting device 5 according to the placement position of the metal composite plate. When the lead screw 402 drives the cross beam 403 and the vacuum suction cup lifting device 5 to move upward and pull the metal composite plate, the tension sensor 503 between the moving block 501 and the fixing plate 504 can detect the tension value. Therefore, the maximum bonding strength value when the metal composite plate and the test piece are stretched and separated can be detected through the tension sensor 503.

[0025] A detection process for the bonding strength of a metal composite plate includes the following detection steps: Step 1: Bond the metal composite plate to the test piece, and perform negative pressure adsorption on the test piece of the metal composite plate through the vacuum suction cup fixture 1; Step 2: Drive the walking frame 4 to move along the linear guide rail 2 through the linear slider 3, so that the vacuum suction cup lifting device 5 is aligned with and adsorbs the metal composite plate to be detected; Step 3: Drive the horizontally placed support mechanism 6 to be vertically unfolded through the towing rope 708 of the towing mechanism 7, and the two groups of support mechanisms 6 adjust the unfolding positions according to the moving position of the walking frame 4, so that the two groups of protective curtains 8 cover both sides of the walking frame 4, facilitating personnel to observe safely; Step 4: Assist through the vacuum suction cup fixture 1 and the vacuum suction cup lifting device 5 to perform tensile detection on the bonding strength of the metal composite plate bonded to the test piece.
