Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and specifically relates to a neodymium iron boron cross-cut test device. Background Technology

[0002] In practical applications, neodymium iron boron materials are enhanced with surface coatings to improve their corrosion resistance. The adhesion of these coatings directly affects product quality. Coating adhesion is typically tested using a cross-cut test. By marking the coating with a test head and observing any bulging or peeling, the adhesion of the coating can be determined.

[0003] Neodymium iron boron (NdFeB) products require cross-cut testing according to different customer requirements. Since NdFeB products for different applications vary in size, existing cross-cut testing equipment generally uses a telescopic cylinder to drive the test head to move along the X and Y axes for cross-cutting. This cylinder-driven method ensures that the distance the test head moves along the X and Y axes is fixed each time, meaning the number of cuts and the spacing between cuts are fixed. This method can only test single, larger products. To test smaller products, multiple smaller products need to be joined together, and then cross-cutting is performed on the joined product. The test head tends to pass through the gaps between adjacent products, failing to skip these gaps, leading to data inaccuracies. Therefore, the existing cylinder-driven test head method is not flexible enough for testing smaller products. Furthermore, the telescopic cylinder will reset after it stops, making it impossible to continue marking from the previous stopping position. The product position needs to be adjusted, but the product position is fixed and cannot be adjusted. Even if small-sized products can be adjusted, their size is too small, and it is difficult to find the marking position after adjusting the position. Moreover, the marked lines may be repeated, and some products may not be marked at all, making it difficult to continue the inspection and affecting the inspection work.

[0004] Currently, cross-cutting tests for small-sized NdFeB products can only be performed manually by arranging and assembling the materials, and then manually cutting the grids. This results in uneven grid sizes, high grid intensity, operator fatigue, and poor consistency. Utility Model Content

[0005] The purpose of this invention is to provide a neodymium iron boron cross-cut test device, which can freely set the number of cuts and the interval between cuts, and can test products of various sizes and specifications.

[0006] To achieve the above objectives, the solution of this utility model is as follows: a neodymium iron boron cross-cut test device, comprising a first precision lead screw, a second precision lead screw, a first transmission motor, a second transmission motor, a transmission plate, a slider, and a test head. The first precision lead screw is arranged along the X-axis and connected to the first transmission motor. The transmission plate is screwed onto the first precision lead screw. The second precision lead screw is arranged along the Y-axis and connected to the second transmission motor. The slider is screwed onto the second precision lead screw. The slider is driven by the first and second precision lead screws to move along the X-axis and Y-axis. The test head is mounted on the slider and moves with the slider.

[0007] Furthermore, both the first drive motor and the second drive motor are connected to the PLC controller via signal connection.

[0008] Furthermore, the cross-cutting test device also includes a loading platform, on which a turntable for mounting products is provided. The turntable is rotatably mounted on the loading platform, and the test head is positioned above the turntable.

[0009] Furthermore, the cross-cutting test device also includes a frame, on which the first precision lead screw, the second precision lead screw, and the first transmission motor are all mounted, and the second transmission motor is mounted on a transmission plate. The frame or loading platform is movable.

[0010] Furthermore, the cross-cutting test device also includes a fixedly installed guide rod, which is arranged parallel to the first precision lead screw. One end of the transmission plate is screwed to the first precision lead screw, and the other end of the transmission plate is sleeved on the guide rod.

[0011] Furthermore, one or both ends of the guide rod are fixed with guide plates, and the guide plates are fixed on the frame.

[0012] Furthermore, the cross-cutting test device also includes two first mounting plates and two second mounting plates. The first mounting plates are fixed on the frame, and the two ends of the first precision lead screw are respectively rotatably mounted on the two first mounting plates. One end of the first precision lead screw extends outward from the first mounting plate and is connected to the first drive motor. The second mounting plate is fixed on the drive plate, and the two ends of the second precision lead screw are respectively rotatably mounted on the two second mounting plates. One end of the second precision lead screw extends outward from the second mounting plate and is connected to the second drive motor.

[0013] Furthermore, the first precision lead screw, the second precision lead screw, and the first transmission motor are all mounted on the loading platform, while the second transmission motor is mounted on the transmission plate.

[0014] Furthermore, the top of the test head is provided with a pressure-applying device, which applies pressure to the test head to move it downwards to perform grid marking.

[0015] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0016] This invention employs a first precision lead screw and a second precision lead screw to drive the test head to move along the X and Y axes to achieve cross-cutting. The displacement of the test head can be precisely set through the pitch transmission of the precision lead screws, resulting in high transmission accuracy and small error. The first and second precision lead screws are driven by a first drive motor and a second drive motor, respectively, which can be controlled by a PLC controller. Through PLC program settings, the number of cuts and the cut spacing can be freely set. For example, the gap between adjacent products can be skipped, and the cut can be made directly on the next product, avoiding deviations in test data and enabling cross-cutting testing of small-sized products. Therefore, this invention can test products of various sizes. Furthermore, the precision lead screws do not reset after stopping, allowing subsequent cuts to continue from the previously stopped position without adjusting the product's position, thus not affecting the testing process.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-2As shown, this utility model provides a NdFeB cross-cut testing device, including a first precision lead screw 1, a second precision lead screw 2, a first transmission motor 3, a second transmission motor 4, a transmission plate 5, a slider 6, and a test head 7. The first precision lead screw 1 is arranged along the X-axis and connected to the first transmission motor 3. The transmission plate 5 is screwed onto the first precision lead screw 1. The first transmission motor 3 can drive the first precision lead screw 1 to rotate, thereby driving the transmission plate 5 to move along the X-axis. The second precision lead screw 2 is arranged on the transmission plate 5, and the second precision lead screw 2 is arranged along the Y-axis and connected to the second transmission motor 4. The slider 6 is screwed onto the second precision lead screw 2. The second transmission motor 4 can drive the second precision lead screw 2 to rotate, thereby driving the slider 6 to move along the Y-axis. The test head 7 is mounted on the slider 6 and can move with the slider 6 along the X-axis and Y-axis to realize cross-cut testing of the product.

[0023] This invention employs a precision lead screw to drive the test head 7 to move along the X and Y axes. The displacement of the test head 7 can be precisely set through the pitch transmission of the precision lead screw, resulting in high transmission accuracy and small error. Both the first drive motor 3 and the second drive motor 4 can be connected to a PLC controller (not shown in the figure) for signal control. The PLC program can be set on the screen software, allowing for free setting of the number of grids and the grid spacing. For example, at the gap between adjacent products, an interval of two grid widths can be set, allowing the test head 7 to skip the gap and directly scribe lines on the next product, avoiding deviations in test data and enabling grid testing of small-sized products. Of course, this invention can also perform grid testing on individual products, applicable to both large and small products. Furthermore, when the precision lead screw stops running, such as during a power outage, it will not reset. Upon restarting, it can continue grid testing from the previous position without adjusting the product's position, thus not affecting the testing process.

[0024] Key references Figure 1The cross-cut testing device also includes a loading platform 8 for mounting products. After the products are mounted on the loading platform 8, the test head 7 moves above the products to perform cross-cutting. A pressure device 13 is provided on the top of the test head 7 to apply pressure to the test head 7, causing it to move downwards to perform cross-cutting. The first precision lead screw 1 and the second precision lead screw 2 can drive the test head 7 to perform cross-cutting along the X and Y axes, or only drive the test head 7 to perform cross-cutting along the Y axis. That is, after the second precision lead screw 2 drives the test head 7 to move along the Y axis and complete the cross-cutting, the first precision lead screw 1 drives the test head 7 to move one grid distance along the X axis, and then the second precision lead screw 2 drives the test head 7 to perform cross-cutting along the Y axis again. This cycle is repeated to complete all Y-axis cross-cutting. During this process, when encountering gaps between products, the first precision lead screw 1 can be set to drive the test head 7 to move two grids before performing Y-axis cross-cutting to avoid gaps between products. This marking method requires a turntable 9 to be set on the loading platform 8. The product is installed on the turntable 9. Specifically, before testing, the product is fixed to an iron plate. If it is a single product, it is directly fixed to the iron plate. If it is multiple small-sized products, the multiple products are spliced ​​and fixed to the iron plate. Then the iron plate is installed on the turntable 9 to complete the product installation. The turntable 9 is rotatably set on the loading platform 8. The test head 7 is set above the turntable 9. After the test head 7 has marked all the Y-axis lines, the turntable 9 is rotated 90 degrees to continue driving the test head 7 to mark the Y-axis, which can also complete the cross-cut test.

[0025] In one embodiment, such as Figure 1 As shown, the cross-cutting test device also includes a frame 10. The first precision lead screw 1, the second precision lead screw 2, and the first drive motor 3 are all mounted on the frame 10, and the second drive motor 4 is mounted on the transmission plate 5. The frame 10 or the loading platform 8 is movable. For example, casters are provided at the bottom of the frame 10 or the loading platform 8. After the product is installed on the turntable 9, the loading platform 8 can be moved to the bottom of the test head 7 for testing, or the frame 10 can be moved so that the test head 7 is above the product for testing. This arrangement facilitates the installation of the product before testing and the removal of the product after testing.

[0026] Furthermore, the cross-cutting test device also includes two first mounting plates 11 and two mounting plates 12. The first precision lead screw 1 and the second precision lead screw 2 are rotatably mounted on the frame 10 via the first mounting plates 11 and the second mounting plates 12, respectively. Specifically, the first mounting plate 11 is fixed on the frame 10, and the two ends of the first precision lead screw 1 are rotatably mounted on the two first mounting plates 11, with one end of the first precision lead screw 1 extending outward from the first mounting plate 11 and connected to the first drive motor 3; the second mounting plate 12 is fixed on the drive plate 5, and the two ends of the second precision lead screw 2 are rotatably mounted on the two second mounting plates 12, with one end of the second precision lead screw 2 extending outward from the second mounting plate 12 and connected to the second drive motor 4.

[0027] Preferably, the cross-cut testing device further includes a fixedly mounted guide rod 14, which is parallel to the first precision lead screw 1. One end of the transmission plate 5 is screwed to the first precision lead screw 1, and the other end of the transmission plate 5 is sleeved on the guide rod 14. The guide rod 14 has a guiding and supporting function, and can support the stable movement of the transmission plate 5. The guide rod 14 is fixed to the frame 10 by guide plates 15. The number of guide plates 15 can be one or two. In this embodiment, it is preferable to set one guide plate 15 and fix it to the frame 10. One end of the guide rod 14 is fixed to the guide plate 15. This arrangement can leave enough space to assemble the product under the test head 7. Of course, in order to make the support of the guide rod 14 more stable, two guide plates 15 can be set and fixed to the frame 10, and the two ends of the guide rod 14 are respectively fixed to the two guide plates 15.

[0028] In another embodiment, such as Figure 2 As shown, the first precision lead screw 1, the second precision lead screw 2, and the first drive motor 3 can all be directly mounted on the loading platform 8 without the need for a frame 10 to install the above structure. The second drive motor 4 is also mounted on the transmission plate 5. The turntable 9 is located below the first precision lead screw 1 and the second precision lead screw 2. The product needs to be installed below the first precision lead screw 1 and the second precision lead screw 2. In addition, the mounting plate and the guide plate 15 can also be fixed on the loading platform 8.

[0029] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
