Description

Technical Field

[0001] The present application relates to the technical field of weighing and metering, and further to a fork tooth structure, a sample transfer mechanism and an automatic weak magnetic detection device for metal materials. Background Art

[0002] In recent years, with the continuous deepening of the application of magnetic materials, the impact of magnetic fields on instruments, equipment, surrounding personnel, environment, etc. has gradually been paid attention to. For example, since electronic balances work on the principle of electromagnetic force balance compensation; when using electronic balances to weigh weights, the weights are in the external magnetic field of the coil inside the balance; when the weights themselves have a certain degree of magnetism, or the weights have a large magnetic susceptibility and are magnetized by the magnetic field of the balance, they will interact with the external magnetic field to produce some force effects, which cannot be distinguished from the weight's own gravity, and will affect the accuracy of the weighing results; therefore, the weight verification procedure requires that before the conversion mass verification, the magnetism of the mass standard should be measured to ensure that the magnetic effect can be ignored.

[0003] At present, weak magnetism in metal materials is mainly tested by magnetic susceptibility meters. In related technologies, magnetic automatic detection devices basically adopt a clamping method to pick up weights and wait for the sample to be tested. However, this method is not only easy to scratch the surface of the sample, but also there are cases where the sample fails to be picked up or cannot be picked up. The reliability and versatility are both low, and there is room for improvement. Utility Model Content

[0004] The purpose of the present application is to provide a fork structure, a sample transfer mechanism and an automatic weak magnetic detection device for metal materials, so as to improve the versatility of the sample transfer mechanism, ensure stable and reliable sample picking, and avoid sample damage as much as possible.

[0005] The technical solutions provided by this application are as follows:

[0006] In one aspect, the present application provides a fork tine structure, comprising:

[0007] A load-bearing plate, wherein a plurality of the load-bearing plates are arranged vertically and the length direction of the load-bearing plates are arranged horizontally; the plurality of load-bearing plates are arranged parallel and spaced along the thickness direction thereof, and a horizontal support plane for supporting the sample is formed at the upper end;

[0008] A bottom plate is arranged at one end of the plurality of the bearing plates and fixedly connects the plurality of the bearing plates.

[0009] According to a fork tine structure provided by the present application, a bottom plate and a plurality of parallel and spaced supporting plates are assembled to form a fork tine structure, which can be used to carry samples and take and place samples; in practical applications, at least two sets of the fork tine structures are usually provided for use, one set is used to carry samples, and the other set is used to take and place samples. Specifically, after the sample is placed on the supporting plane of one set of fork tine structures, the other set of fork tine structures is combined with a mobile device such as a mechanical arm, and inserted into the fork tine structure corresponding to the sample placement from the gap below the supporting plane along the length direction of the supporting plate, and moved from bottom to top relative to the fork tine structure where the sample is placed, so that the sample can be transferred between different fork tine structures, that is, the sample is picked up from the supporting plane from bottom to top; or, after the fork tine structure combined with a mobile device such as a mechanical arm picks up the sample, it is inserted into the gap between the multiple supporting plates on another fork tine structure from top to bottom, and the sample can be re-placed on the supporting plane of another fork tine structure from top to bottom relative to the other fork tine structure, that is, the sample is transferred from the sample picking component to the sample receiving component.

[0010] The method of transferring samples by lifting the samples from top to bottom and placing them from bottom to top effectively reduces the probability of hard contact between the sample picking component and the sample during the sample transfer process, thereby effectively reducing the occurrence of damage and scratches on the sample picking component and improving the safety of the sample transfer operation.

[0011] At the same time, the sample is supported by the fork structure to achieve the picking and transfer of the sample, instead of using the claws to clamp the sample in the related technology. As long as the sample has a bottom surface of a certain shape or size, the sample can be picked up. The fork structure has a wider range of use and strong versatility. It can effectively reduce the probability of sample grabbing failure or inability to grab the sample due to the mismatch between the size, shape, etc. and the picking component, thereby effectively improving the stability and reliability of the sample picking and transfer operations.

[0012] In some embodiments, the support plane is formed with a first support position and a second support position, the first support position includes two, and the second support position is located between the two first support positions;

[0014] A fork tine structure provided in the present application, in which a first supporting position and a second supporting position are arranged in sequence and at intervals, helps to accurately position the sample on the supporting plane. At the same time, it allows samples of various sizes to be placed on the fork tine structure, which helps to improve the practicality of the fork tine structure.

[0015] In some embodiments, the lengths of the plurality of bearing plates forming the first supporting position are consistent and are greater than the lengths of the plurality of bearing plates forming the second supporting position;

[0016] The lengths of the plurality of bearing plates forming the second supporting position are consistent.

[0017] Through a fork tine structure provided by the present application, a plurality of supporting plates at the first supporting position are longer than a plurality of supporting plates at the second supporting position, so that the supporting plates on the fork tine structure are short in the middle and long on the outside; on the one hand, the first supporting position and the second supporting position are distinguished in this way, and the first supporting position and the second supporting position are easy to distinguish and convenient to use; on the other hand, when the sample is placed on the supporting plane of the fork tine structure, it is not easy to fall, which effectively expands the tolerance range of the deviation of the sample positioning process of the fork tine structure, improves the safety of the sample taking and placing process, and improves the sample picking rate; at the same time, the sample can be quickly and accurately positioned on the supporting plane through a simple structure, and the fork tine structure is easy to produce and low in cost, which is beneficial to energy saving and cost reduction for enterprises.

[0018] In some embodiments, the distances between the multiple bearing plates forming the first supporting position are consistent and greater than the distances between the multiple bearing plates forming the second supporting position;

[0019] The distances between the multiple bearing plates forming the second supporting position are consistent.

[0020] Through a fork tine structure provided by the present application, the gaps between the multiple bearing plates at the first supporting position are set to be larger than the gaps between the multiple bearing plates at the second supporting position, so that the bearing plates on the fork tine structure are dense in the middle and sparse on the periphery, which helps the fork tine structure to be suitable for samples with a wider range of bottom diameter sizes, thereby expanding the scope of application of the fork tine structure and enhancing its practicality.

[0021] On the other hand, the present application further provides a sample transfer mechanism, including a sample library, the sample library including a placement table and a first fork structure, the placement table is horizontally arranged, the first fork structure is horizontally placed on the placement table for storing samples; the length direction of the carrier plate on the first fork structure is parallel to the sampling direction of the placement table;

[0022] A sample receiving platform, wherein a third fork structure is horizontally arranged on the sample receiving platform for placing the sample transferred from the sample library;

[0023] a single-arm robot, arranged between the sample library and the sample receiving platform, the single-arm robot being provided with a second fork tine structure, the second fork tine structure being installed at the movable end of the mechanical arm of the single-arm robot, and being used for being inserted into the gaps of the plurality of the supporting plates of the first fork tine structure to lift the sample from bottom to top, and after picking up the sample, being inserted into the gaps of the plurality of the supporting plates of the third fork tine structure to transfer the sample from top to bottom to the third fork tine structure;

[0024] The first fork tine structure, the second fork tine structure and the third fork tine structure all include any of the fork tine structures described above.

[0025] In some embodiments, the bottom plates of the first fork tine structure and the third fork tine structure are both arranged at an end of the corresponding carrying plate away from the supporting platform;

[0026] The bottom plate of the second fork structure is arranged at one end corresponding to the length direction of the carrying plate;

[0027] The movable end of the single-arm robot mechanical arm is fixedly connected to the bottom plate of the second fork structure.

[0028] Through a fork tine structure provided by the present application, the bottom plates of the first fork tine structure and the third fork tine structure are arranged at one end of the corresponding load-bearing plate away from the supporting platform, and the bottom plate of the second fork tine structure is arranged at one end of the corresponding load-bearing plate in the length direction, so as to facilitate the insertion of the load-bearing plate of the second fork tine structure into the gap between the load-bearing plates of the corresponding first fork tine structure and the third fork tine structure, and to lift the sample from bottom to top or place the sample from top to bottom, so as to smoothly carry out the corresponding sample taking and placing operation. At the same time, the first fork tine structure, the second fork tine structure and the third fork tine structure are simple in structure, easy to produce and use, effectively reducing the corresponding cost investment of enterprises and users, and facilitating energy saving and cost reduction.

[0029] In some embodiments, the second fork tine structure further includes a mounting plate, the mounting plate is fixedly connected to the bottom plate and extends upward from the supporting plane in a direction perpendicular to the supporting plane;

[0030] The movable end of the single-arm robot mechanical arm is arranged on a side of the mounting plate away from the bearing plate, and is detachably fixedly connected to an end of the mounting plate away from the base plate.

[0031] Through a sample transfer mechanism provided by the present application, a mounting plate is further provided on the second fork tooth structure, and the movable end of the single-arm robot arm is connected through the mounting plate. The movable end of the single-arm robot arm is arranged away from the supporting plane, which helps to reduce the occurrence of the movable end of the single-arm robot arm touching and damaging the sample surface when taking and placing samples, thereby further improving the safety of the sample transfer operation; at the same time, such a setting also facilitates the second fork tooth structure to extend into the sample library to pick up and place samples, which helps to improve the convenience and safety of the corresponding sample taking and placing operations.

[0032] In some embodiments, a width dimension of the supporting plate on the second tine structure is smaller than a width dimension of the supporting plate on the first tine structure and the third tine structure.

[0033] Through a sample transfer mechanism provided by the present application, the width dimension of the supporting plate on the second fork structure is set to be smaller than the width dimension of the supporting plate on the first fork structure and the third fork structure, so that the supporting plate of the second fork structure can be quickly and accurately inserted into the gap between the adjacent supporting plates on the corresponding first fork structure and the third fork structure without touching the sample, thereby further improving the convenience and safety of sample placement operations.

[0034] In some embodiments, the support plane of the third tine structure is formed with a plurality of concentric ring patterns of different sizes;

[0035] The centers of the multiple concentric ring patterns are collinear with the center of the sample receiving platform.

[0036] Through a sample transfer mechanism provided by the present application, concentric ring patterns are arranged on the third fork structure, so that the sample can be placed at the center of the sample receiving table when the sample is placed manually, thereby improving the accuracy of manual operation.

[0037] On the other hand, the present application also provides a metal material weak magnetism automatic detection device, comprising any of the above-mentioned sample transfer mechanisms, and further comprising:

[0038] Working platform; the sample library, the sample receiving platform and the single-arm robot are all arranged on the working platform;

[0039] The mass comparator is installed on the working platform; the sample receiving platform is placed above the weighing part of the mass comparator and is used to weigh the sample.

[0040] Through the weak magnetic automatic detection device of metal materials provided by the present application, in actual application, samples of different specifications are placed one by one on the first supporting position and / or the second supporting position of the supporting plane of the placement table; during the magnetic detection operation, the active end of the single-arm robot mechanical arm drives the second fork tine structure to first move to the placement table of the sample library, and is inserted between the multiple supporting plates of the first fork tine structure along the sampling direction of the placement table, and then moves from bottom to top relative to the first fork tine structure, so that the corresponding sample to be tested is transferred from the supporting plane of the first fork tine structure to the supporting plane of the second fork tine structure, thereby realizing the single-arm robot's picking operation of the sample to be tested; thereafter, the active end of the single-arm robot mechanical arm drives the second fork tine structure and the sample to be tested thereon to be transferred to the top of the sample receiving table of the mass comparator, and drives the second fork tine structure to be inserted between the multiple supporting plates of the third fork tine structure, and then drives the second fork tine structure to move from top to bottom relative to the third fork tine structure until the sample is transferred from the supporting plane of the second fork tine structure to the supporting plane of the third fork tine structure, thereby realizing the loading process of the sample to be tested on the mass comparator.

[0041] The method of transferring samples by lifting the samples from top to bottom and placing the samples from bottom to top effectively reduces the probability of sample grabbing failure and / or inability to grab the samples due to the mismatch between the size, shape, etc. and the sample grabbing component of the magnetic automatic detection device, thereby effectively improving the versatility of the corresponding magnetic automatic detection device and the reliability and stability of sample placement during the magnetic automatic detection process; at the same time, it effectively reduces the probability of damage and scratches on the sample surface during the sample placement process, thereby ensuring the safety of use of the corresponding magnetic automatic detection device.

It has a simple structure and strong versatility, which helps to significantly reduce the production costs of enterprises. Moreover, when using this fork tine structure to carry and take and place samples, it is only necessary to lift the samples from bottom to top and place the samples from top to bottom. The sample taking and placing operation is simple and the operation efficiency is high. At the same time, it is not limited by the shape and size of the samples, and the probability of sample grabbing failure and / or inability to grab the samples due to the mismatch between the size, shape, etc. and the sample grabbing component is effectively reduced, and the tine structure has a stronger versatility. In addition, since there is no hard conflict with the sample, it can effectively avoid the sample grabbing component from being damaged or scratched during the sample taking and placing process, and the use safety is high.

[0044] 2. In the present application, the supporting plate of the fork tine structure is short in the middle and long on the outside, dense in the middle and sparse on the outside, which effectively reduces the error requirements of the fork tine structure in the process of positioning the sample and improves the convenience and safety of the sample taking and placing process; at the same time, the fork tine structure can be used in sampling scenarios of samples of more sizes, effectively expanding the scope of application of the fork tine structure and improving its practicality.

[0055] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0056] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0057] In recent years, with the continuous deepening of the application of magnetic materials, the impact of magnetic fields on instruments, equipment, surrounding personnel, environment, etc. has gradually been paid attention to. The so-called non-magnetic materials, in addition to materials that do not contain magnetism themselves (such as copper and aluminum), also include some weak magnetic materials with low magnetic induction and relative magnetic permeability μ close to 1 (such as non-magnetic stainless steel, etc.). The weak magnetism in non-magnetic materials mainly refers to the relative magnetic susceptibility and magnetic induction intensity, which can be tested by methods such as magnetic susceptibility meters. At present, in the relevant technology, the weak magnetism in metal materials is mainly tested by magnetic susceptibility meters, and the domestically produced automatic magnetic detection devices basically use a clamping grabbing mode to pick up the weights and wait for the sample to be measured; however, this method is not only easy to scratch the surface of the sample, but also there are cases where the sample fails to be picked up or cannot be picked up, and the reliability and versatility are low.

[0058] In this regard, in one embodiment, referring to the accompanying drawings of the specification Figures 1 to 7 , provides a fork tine structure, including multiple supporting plates 11 and a bottom plate 12 connecting the multiple supporting plates 11; wherein the multiple supporting plates 11 are vertically arranged, and their length directions are horizontally arranged, the multiple supporting plates 11 are arranged in parallel and spaced along their own thickness directions, and form a horizontal supporting plane 13 at the upper end for supporting samples; the bottom plate 12 is connected to one end of the multiple supporting plates 11.

[0059] In practical applications, at least two sets of the fork tine structure are provided for use in combination, which are used for carrying samples and for taking and placing samples respectively; for example, in weak magnetic detection of metals, when measuring the magnetism of weights, two sets of the fork tine structure are provided, one of which is used for carrying weights, specifically, the weights are placed on the supporting plane 13 of the corresponding fork tine structure; the other set is used in conjunction with moving equipment such as a robotic arm, keeping the length direction of the carrying plate 11 thereon consistent with the length direction of the carrying plate 11 of the fork tine structure carrying the weights, and inserting it between the multiple carrying plates 11 of the fork tine structure for carrying the weights along the length direction of its own carrying plate 11, and moving from bottom to top relative to the fork tine structure for carrying the weights, thereby transferring the weights on the supporting plane 13 of the fork tine structure for carrying the weights to the supporting plane 13 of another fork tine structure used in conjunction with moving equipment such as a robotic arm, thereby completing the weight picking process. Similarly, when the weight is placed on the test platform of the mass comparator 7, the fork structure used in conjunction with a mobile device such as a mechanical arm picks up the weight, inserts it into the gap between the multiple bearing plates 11 of another fork structure on the test platform of the mass comparator 7, and moves from top to bottom relative to the fork structure on the test platform until the weight is transferred to the supporting plane 13 of the test platform of the mass comparator 7, thereby completing the weight placement process. Of course, the action of picking up the weight from the test platform of the mass comparator 7 after the weight test is completed and the action of resetting the weight to the weight library are consistent with the above-mentioned action process, and will not be repeated here.

[0060] The sample is transferred by lifting the sample from top to bottom and placing the sample from bottom to top. Since there is no hard contact with the sample, it is effectively avoided that the sample picking component is damaged or scratched due to positioning errors during the sample picking and placing process, and the sample transfer operation is safer. At the same time, by supporting the sample to pick and place the sample, the probability of sample grabbing failure and / or inability to grab the sample due to the mismatch between the sample's own shape and size and the sample picking component is effectively reduced. The fork tine structure is more versatile, and the process of picking up samples is more reliable and stable. At the same time, it is simple in overall design, easy to produce and use, and helps to reduce the relevant cost investment of enterprises and users.

[0061] In one embodiment, based on the above embodiment, specifically, referring to Figure 1 and Figure 2 In this embodiment of the present application, multiple supporting plates 11 are sequentially arranged along their thickness direction, so that the length direction of the fork structure is parallel to the thickness direction of the supporting plate 11, that is, the length direction of the supporting plane 13 is parallel to the thickness direction of the supporting plate 11. In the embodiment of the present application, the supporting plane 13 is sequentially formed with a first supporting position 131 and a second supporting position 132 along its length direction, and the first supporting position 131 and the second supporting position 132 are respectively used to support samples of different sizes. Specifically, refer to Figure 1 There are two first supporting positions 131 , and the second supporting position 132 is located between the two first supporting positions 131 , and there is a natural transition between the first supporting position 131 and the second supporting position 132 .

[0062] In this embodiment of the present application, the lengths of the multiple supporting plates 11 forming the first supporting position 131 are consistent, the lengths of the multiple supporting plates 11 forming the second supporting position 132 are consistent, and the length of the supporting plate 11 forming the first supporting position 131 is greater than the length of the supporting plate 11 forming the second supporting position 132. In this way, since the supporting plate 11 forming the supporting plane 13 is short in the middle and long at the periphery, when the sample is placed on the supporting plane 13, its placement stability on the supporting plane 13 can be significantly improved, and when the fork structure is used to take and place the sample, the influence of the positioning error on the accuracy of the sample taking and placing operation can be significantly reduced, effectively ensuring the stability and safety of the fork structure in carrying the sample and / or taking and placing the sample.

[0063] At the same time, the distances between the multiple supporting plates 11 forming the first supporting position 131 are consistent, the distances between the multiple supporting plates 11 forming the second supporting position 132 are consistent, and the distances between the multiple supporting plates 11 forming the first supporting position 131 are greater than the distances between the multiple supporting plates 11 forming the second supporting position 132; thus, since the array of supporting plates 11 forming the supporting plane 13 is dense in the middle and sparse at the periphery, the sample can be first placed at the second supporting position 132 in the middle of the supporting plane 13, thereby significantly improving the bearing capacity of the supporting plane 13, making it suitable for samples with a wider range of bottom diameter sizes, effectively enhancing its applicability.

[0064] The following further describes the technical solution by applying the fork structure to a specific sample transfer mechanism. Figures 1 to 7 A sample transfer mechanism includes a sample library 5, a single-arm robot 6, a sample receiving platform 71, and a first fork structure 1, a second fork structure 2, and a third fork structure 3, wherein the first fork structure 1, the second fork structure 2, and the third fork structure 3 all include the fork structure described in the above embodiment.

[0065] Specifically, a placement table 51 is provided on the sample library 5, and the placement table 51 is arranged horizontally. The first fork tine structure 1 is horizontally installed on the placement table 51, and the length direction of the first fork tine structure 1 is arranged along the length direction of the placement table 51, that is, the first support position 131 and the second support position 132 are arranged in sequence along the length direction of the placement table 51; at the same time, the length direction of the carrier plate 11 on the first fork tine structure 1 is parallel to the sampling direction of the placement table 51, and the samples are placed one by one on the first support position 131 and / or the second support position 132 of the first fork tine structure 1. The third fork tine structure 3 is horizontally installed on the sample receiving table 71, and is used to receive samples transferred from the sample library 5. The single-arm robot 6 is arranged between the sample library 5 and the sample receiving table 71, and the second fork structure 2 is installed at the movable end of the mechanical arm of the single-arm robot 6, and is used to move along the sampling direction of the placement table 51 when picking up the sample, and cooperate to insert into the gap of multiple supporting plates 11 of the first fork structure 1 to support the sample to be tested from bottom to top; and after picking up the sample to be tested and transferring the sample to the top of the sample receiving table 71 under the drive of the mechanical arm of the single-arm robot 6, cooperate to insert into the gap of multiple supporting plates 11 of the third fork structure 2, and move from top to bottom relative to the third fork structure 3 to transfer the sample on its supporting plane 13 to the supporting plane 13 of the third fork structure 3.

[0066] In one embodiment, based on the above embodiment, specifically, referring to Figure 1 and Figure 2In this embodiment of the present application, in order to facilitate the first fork tine structure 1 and the third fork tine structure 3 to be stably placed on the corresponding placement table 51 and the sample receiving table 71 respectively, in this embodiment of the present application, the bottom plates 12 of the first fork tine structure 1 and the third fork tine structure 3 are fixedly connected to the end of the corresponding supporting plate 11 away from the supporting platform, and the bottom plate 12 of the second fork tine structure 2 is fixedly connected to one end of the corresponding supporting plate 11 in the length direction, so as to smoothly extend into the gaps of the corresponding supporting plates 11 on the first fork tine structure 1 and the third fork tine structure 3, thereby realizing the picking action of the corresponding samples on the first fork tine structure 1 and the third fork tine structure 3.

[0067] Of course, in the embodiment of the present application, the bottom plate 12 of the first fork tine structure 1 and the third fork tine structure 3 can also be arranged at one end of the length direction of the corresponding supporting plate 11; when so arranged, the end of the first fork tine structure 1 and the third fork tine structure 3 away from the bottom plate 12 should face the sampling direction of the second fork tine structure 2, that is, the end of the first fork tine structure 1 and the third fork tine structure 3 away from the bottom plate 12 is close to the operating space of the second fork tine structure 2, so that the second fork tine structure 2 can be smoothly inserted into the gap between the corresponding multiple supporting plates 11 on the first fork tine structure 1 and the third fork tine structure 3, and can hold up the sample from bottom to top, or place the sample from top to bottom on the corresponding placement table 51 or supporting plane 13. Of course, the bottom plate 12 of the first fork tine structure 1 and the third fork tine structure 3 can also be arranged at other positions according to the size of the corresponding supporting plate 11. In this embodiment of the present application, only the bottom plate 12 of the first fork tine structure 1 and the third fork tine structure 3 is fixedly connected to the end of the corresponding supporting plate 11 away from the supporting plane 13 as an example for explanation.

[0068] Moreover, in the embodiment of the present application, the width dimension of the corresponding supporting plate 11 on the first fork tine structure 1 and the third fork tine structure 3 is significantly larger than the width dimension of the corresponding supporting plate 11 on the second fork tine structure 2, so that the corresponding supporting plate 11 of the second fork tine structure 2 can be quickly and accurately inserted into the gap between the corresponding supporting plates 11 on the first fork tine structure 1 and the third fork tine structure 3 without touching the sample on the supporting plane 13, thereby ensuring the convenience and safety of the sample placement operation.

[0069] Reference Figure 2 and Figure 6 In order to facilitate the installation of the second fork tooth structure 2 on the movable end of the single-arm robot 6 mechanical arm, in this embodiment of the present application, the second fork tooth structure 2 also includes a mounting plate 21, and the mounting plate 21 is arranged corresponding to the base plate 12, and extends above the supporting plane 13 in a direction perpendicular to the supporting plane 13, and is fixedly connected to the base plate 12, and the movable end of the single-arm robot 6 mechanical arm is located on the side of the mounting plate 21 away from the supporting plate 11 of the second fork tooth structure 2.

[0070] In this embodiment of the present application, the mounting plate 21 can be detachably mounted on the movable end of the mechanical arm of the single-arm robot 6 by tightening bolts, so as to facilitate the adjustment of the horizontality of the second fork tine structure 2 on the single-arm robot 6, thereby ensuring that the second fork tine structure 2 can smoothly pick up and transfer the sample. Of course, in the embodiment of the present application, the detachable connection between the mounting plate 21 and the single-arm robot 6 can also be achieved by welding, clamping, etc., which will not be described one by one here.

[0071] In addition, the movable end of the single-arm robot 6 arm is fixedly connected to the end of the mounting plate 21 facing away from the base plate 12, so that the movable end of the single-arm robot 6 arm is arranged away from the supporting plane 13, thereby avoiding as much as possible the situation where the second fork structure 2 touches, damages or scratches the sample by the movable end of the single-arm robot 6 arm during the sample taking and placing process, thereby further improving the safety of the sample transfer operation of the corresponding sample transfer mechanism.

[0072] In addition, in order to expand the scope of application of the corresponding sample transfer mechanism, in other words, to make the corresponding sample transfer mechanism suitable for manual detection scenarios and to improve the positioning accuracy when the staff manually places the sample in this scenario, in this embodiment of the present application, reference is made to Figure 1 , the upper end of the carrier plate 11 of the third fork tine structure 3 is formed with a plurality of concentric ring patterns 31 of different sizes; in particular, the centers of the plurality of concentric ring patterns 31 on the third fork tine structure 3 are collinear with the center of the sample receiving platform 71. In practical applications, when the staff manually places the sample on the sample receiving platform 71, they can refer to the position of the concentric ring patterns 31 and quickly place the sample at the center of the sample receiving platform 71, thereby effectively improving the convenience of use of the corresponding sample transfer mechanism. Of course, corresponding concentric ring patterns 31 can also be provided on the first fork tine structure 1 to ensure accurate positioning of the sample on each first fork tine structure 1 on the sample library 5.

[0073] In the implementation manner of the present application, the concentric ring patterns 31 on the first fork tooth structure 1 and the third fork tooth structure 3 can be formed by carving grooves or painting the supporting plate 11, and the setting method of the concentric ring patterns 31 should not be used as a limitation on the protection scope of the present application.

[0074] The following further describes the technical solution by applying the fork structure to a specific magnetic automatic detection scenario. Figures 1 to 7 , a metal material weak magnetic automatic detection device, comprising any of the above-mentioned sample transfer mechanisms, referring to Figure 3 and Figure 4Of course, it also includes a horizontally arranged working platform 4, on which a mass comparator 7 is arranged, and a sample library 5, a single-arm robot 6 and a mass comparator 7 are arranged in sequence along the length direction of the working platform 4; a sample receiving table 71 is used as a test platform for the mass comparator 7, and is arranged above the weighing part of the mass comparator 7 to facilitate weighing of the sample.

[0075] Further, in this embodiment of the present application, refer to Figures 3 to 5 In order to increase the capacity of the sample library 5, the sample library 5 includes a plurality of horizontal placement tables 51 arranged in parallel and at intervals along its own height direction; at the same time, a plurality of first fork tooth structures 1 are placed side by side along the length direction of the corresponding placement table 51, and the bottom plate 12 of any first fork tooth structure 1 is fixedly connected to the corresponding placement table 51 to form a stable sample support position on the placement table 51.

[0076] The implementation principle of the embodiment of the present application is as follows: in actual application, samples of different specifications are placed one by one on different supporting positions of the supporting plane 13 of the placement table 51; during the magnetic detection operation, the movable end of the mechanical arm of the single-arm robot 6 drives the second fork structure 2 to first move to the placement table 51 of the sample library 5, and inserts it between the multiple supporting plates 11 of the first fork structure 1 along the sampling direction of the placement table 51, and then moves from bottom to top relative to the first fork structure 1, so that the corresponding sample to be tested is transferred from the supporting plane 13 of the first fork structure 1 to the supporting plane 11 of the second fork structure 2. 3, realize the picking operation of the single-arm robot 6 on the sample to be tested; then, the movable end of the mechanical arm of the single-arm robot 6 drives the second fork structure 2 and the sample to be tested thereon to be transferred to the top of the test platform of the mass comparator 7, and inserts the second fork structure 2 between the multiple supporting plates 11 of the third fork structure 3, and then drives the second fork structure 2 to move relative to the third fork structure 3 from top to bottom until the sample is transferred from the supporting plane 13 of the second fork structure 2 to the supporting plane 13 of the third fork structure 3, thereby realizing the loading process of the sample to be tested on the mass comparator 7.

[0077] In this way, the sample is picked up and transferred by lifting the sample from top to bottom and placing the sample from bottom to top, which effectively reduces the probability of sample grabbing failure and / or inability to grab due to the mismatch between the size, shape, etc. and the sample grabbing component. The fork tine structure is more versatile and has a wider range of applications. At the same time, since there is no need for hard contact with the sample, the probability of damage and scratching the sample surface during the sample picking and placing process is effectively reduced, and the safety of the corresponding sample picking and placing operation is improved. At the same time, the fork tine structure is simple as a whole, easy to produce and use, low cost, and conducive to energy saving and cost reduction.

[0078] It should be noted that the above embodiments can be freely combined as needed. The above is only the preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
