[0033] To better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below through the accompanying drawings and specific embodiments. It should be understood that the specific features in the embodiments of this specification and the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. Without conflict, the technical features in the embodiments of this specification and the embodiments can be combined with each other.

[0034] Unless otherwise specified, the length direction in this application is the longitudinal direction of the metal sample preparation fixing device, i.e., the X direction; the width direction is the transverse direction of the metal sample preparation fixing device, i.e., the Y direction; and the height direction is the vertical direction of the metal sample preparation fixing device, i.e., the Z direction.

[0035] In the field of metal material testing, the chemical analysis accuracy of metal samples depends on the sample preparation quality of metal samples, including the consistency of metal samples. The metal sample preparation process requires fixing metal raw materials, so metal sample preparation fixing devices need to be applied. Since the shapes of metal raw materials are diverse and the size ranges span a large range, the current metal sample preparation fixing devices have poor adaptability. Therefore, during the metal sample preparation process, it is necessary to frequently replace the metal sample preparation fixing devices, resulting in poor consistency of the finally prepared metal samples.

[0036] In view of this, the embodiments of the present application provide a metal sample preparation fixing device and a metal sample preparation system, which can improve the consistency of the prepared metal samples, thereby improving the chemical analysis accuracy of metal samples, and can also improve the metal sample preparation efficiency.

[0037] In a first aspect, the embodiments of the present application provide a metal sample preparation fixing device, and the metal sample preparation fixing device provided by the embodiments of the present application is applied to a metal sample preparation system. Figure 1It is a schematic perspective view of a metal sample preparation fixing device provided by an embodiment of the present application. The metal sample preparation fixing device 1 includes a bracket 10, and the bracket 10 is provided with a sliding groove 1011. The bracket 10 can be a rectangular plate member, and the sliding groove 1011 is provided at the top of the plate member. The sliding groove 1011 can be a square groove.

[0038] The metal sample preparation fixing device 1 further includes at least two clamping components 20, and the at least two clamping components 20 are sequentially connected in the sliding groove 1011. The clamping component 20 includes a first clamping part 201 and a second clamping part 202 which are oppositely arranged. The first clamping part 201 can move relative to the second clamping part 202 in the sliding groove 1011 along a first direction. Wherein, the first direction is parallel to the length direction of the metal sample preparation fixing device 1, and the first direction is the X direction as shown in Figure 1 the figure.

[0039] The at least two clamping components 20 being sequentially connected in the sliding groove 1011 means that the second clamping part 202 of the clamping component 20 arranged at the first position is connected to the first clamping part 201 of the clamping component 20 arranged at the second position; the second clamping part 202 of the clamping component 20 arranged at the second position is connected to the first clamping part 201 of the clamping component 20 arranged at the third position; the second clamping part 202 of the clamping component 20 arranged at the third position is connected to the first clamping part 201 of the clamping component 20 arranged at the fourth position; and so on; the second clamping part 202 of the clamping component 20 arranged at the last position can be connected to the side wall of the sliding groove 101.

[0040] When the first clamping part 201 is stationary, the second clamping part 202 can move along the X direction inside the sliding groove 1011. When the second clamping part 202 is stationary, the first clamping part 201 can move along the X direction inside the sliding groove 1011. And the first clamping part 201 and the second clamping part 202 can also move along the X direction inside the sliding groove 1011 simultaneously.

[0041] The metal sample preparation fixing device 1 further includes at least one first driving component 30, and the first driving component 30 can at least drive the first clamping part 201 of the clamping component 20 located at the end along the first direction (X direction) to move until the first clamping parts 201 and the second clamping parts 202 of the at least two clamping components 20 can no longer move along the first direction. Here, the clamping component 20 at the end refers to the clamping component 20 close to the first driving component 30.

[0042] The first driving component 30 can drive only the first clamping part 201 of the clamping component 20 located at the end to move in the first direction until the first clamping parts 201 and the second clamping parts 202 of all the clamping components 20 cannot move in the first direction, that is, until all the clamping components 20 clamp the metal raw material clamped between the first clamping part 201 and the second clamping part 202.

[0043] The first driving component 30 can also drive the first clamping part 201 and the second clamping part 202 of the clamping component 20 located at the end to move in the first direction simultaneously until the first clamping parts 201 and the second clamping parts 202 of all the clamping components 20 cannot move in the first direction, that is, until all the clamping components 20 clamp the metal raw material clamped between the first clamping part 201 and the second clamping part 202.

[0044] The first driving component 30 can also drive the first clamping part 201 and the second clamping part 202 of the clamping component 20 located at the end simultaneously, and at the same time drive the first clamping part 201 of the clamping component 20 located at the second position to move in the first direction until the first clamping parts 201 and the second clamping parts 202 of all the clamping components 20 cannot move in the first direction, that is, until all the clamping components 20 clamp the metal raw material clamped between the first clamping part 201 and the second clamping part 202.

[0045] That is to say, the first driving component 30 can fix all the first clamping parts 201 and the second clamping parts 202 in the sliding groove 101 in a variety of driving combination ways. Since the metal raw material is clamped between the first clamping part 201 and the second clamping part 202, the clamping of the metal raw material can be realized simultaneously. In addition, since at least two clamping components 20 are provided in the embodiment of the present application, the clamping of at least two metal raw materials can be realized simultaneously, and the processing of at least two metal raw materials can also be realized simultaneously, improving the consistency and sample preparation efficiency of metal sample preparation.

[0046] Figure 3 It is a schematic enlarged view of the clamping component of a metal sample preparation fixing device provided by an embodiment of the present application. As Figure 3As shown, on the opposite sides of the first clamping portion 201 and the second clamping portion 202 of the metal sample preparation fixing device according to the embodiment of the present application, fixing grooves 203 are provided. The fixing grooves 203 have a stepped structure. The fixing grooves 203 include at least two stepped portions 2031 arranged in sequence along the first direction, and adjacent two stepped portions 2031 are connected by a transition portion 2032. The fixing grooves 203 with the stepped structure can enable the first clamping portion 201 and the second clamping portion 202 to clamp metal raw materials with various shapes and a large span of size ranges. Therefore, when processing metal raw materials with various shapes and a large span of size ranges, it is not necessary to frequently replace the metal sample preparation fixing device, thus improving the consistency of the finally prepared metal samples.

[0047] Figure 3 The fixing grooves 203 with the stepped structure in [reference] have four stepped portions 2031 and four transition portions 2032. The stepped surfaces of the stepped portions 2031 can be perpendicular to the first direction, and the transition surfaces of the transition portions 2032 can be parallel to the first direction.

[0048] As Figure 3 shown, when the opposite sides of the first clamping portion 201 and the second clamping portion 202 are in complete contact, the fixing grooves 203 can be used to clamp a cylindrical metal raw material with a cross-sectional radius of R1. As Figure 4 shown, when there is a certain distance between the opposite sides of the first clamping portion 201 and the second clamping portion 202, the fixing grooves 203 can be used to clamp a cylindrical metal raw material with a cross-sectional radius of R2. Among them, R2 is greater than R1. The distance between the opposite sides of the first clamping portion 201 and the second clamping portion 202 can be adjusted according to the size of R2. It can be seen that by adjusting the distance between the opposite sides of the first clamping portion 201 and the second clamping portion 202, metal raw materials of different sizes can be clamped.

[0049] In addition, Figure 3 shown, due to the stepped fixing grooves 203, the first clamping portion 201 and the second clamping portion 202 can also clamp special-shaped samples such as mushroom-shaped, elliptical-shaped, and square-shaped samples, so as to adapt to the various shape changes of metal raw materials. For example, as Figure 5 and Figure 6 shown, when the opposite sides of the first clamping portion 201 and the second clamping portion 202 are in contact with each other, a metal raw material with an elliptical cross-section can be clamped. Among them, Figure 5 the major axis of the elliptical cross-section of the metal raw material is D1, and the minor axis is D2. Figure 6 the major axis of the elliptical cross-section of the metal raw material is D3, and the minor axis is D4. D1, D2, D3, and D4 are not equal to each other in pairs.

[0050] In some embodiments, the sliding groove has a first side 102 and a second side 103, and the first side 102 and the second side 103 are two sides perpendicular to the first direction. The metal sample fixing device only includes one first driving component 30, and the first driving component 30 is arranged on the first side 102. Then, the connection relationship between the clamping component 20 and other components is as follows.

[0051] The clamping component 20 at the end, that is, the clamping component 20 close to the first side 102, the first clamping part 201 of the clamping component 20 at the end is connected to the first driving component 30, and the second clamping part 202 of the clamping component 20 at the end is connected to the first clamping part 201 of the adjacent clamping component 20, that is, the first clamping part 201 of the clamping component 20 located at the second position. Finally, the second clamping part 202 of the clamping component 20 close to the second side is connected to the second side 103. It should be noted that the connection here refers to the contact state between the first clamping part 201 and the second clamping part 202 in the clamped state. If it is in the unclamped state, the adjacent two clamping parts can also be separated and not connected.

[0052] Exemplarily, continue to refer to Figure 1 , Figure 1 The metal sample fixing device 1 shown includes one first driving component 30 and six clamping components 20. The first clamping part 201 of the clamping component 20 at the end (the first one) is connected to the first driving component 30. The second clamping part 202 of the clamping component 20 at the end is connected to the first clamping part 201 of the second clamping component 20. The second clamping part 202 of the second clamping component 20 is connected to the first clamping part 201 of the third clamping component 20... After connecting in sequence until the second clamping part 202 of the fifth clamping component 20 is connected to the first clamping part 201 of the sixth clamping component 20. Finally, the second clamping part 202 of the sixth clamping component 20 is connected to the second side 103 of the sliding groove 1011.

[0053] Figure 1 When the metal sample fixing device 1 shown is in use, the first clamping part 201 and the second clamping part 202 of each clamping component 20 can be separated, and then the metal raw material to be clamped is placed between the first clamping part 201 and the second clamping part 202. For example, the first clamping component 20 can clamp Figure 3 the metal raw material shown, the second clamping component 20 can clamp Figure 4 the metal raw material shown, the third clamping component 20 can clamp Figure 5 the metal raw material shown, the fourth clamping component 20 can clamp Figure 6 the metal raw material shown... <(

[0054] Figure 1During the clamping process of the metal sample fixing device shown, the first driving component 30 first drives the first clamping part 201 of the first clamping component 20 to move towards the second clamping part 202 of the first clamping component 20. Then, the second clamping part 202 of the first clamping component 20 contacts the first clamping part 201 of the second clamping component 20 and drives the first clamping part 201 and the second clamping part 202 of the second clamping component 20 to move.

[0055] That is to say, the first clamping component 20 and the second clamping component 20 move together towards the third clamping component 20. Then, the second clamping part 202 of the second clamping component 20 contacts the first clamping part 201 of the third clamping component 20 and drives the third clamping component 20 to move towards the fourth clamping component 20. Finally, two adjacent clamping components 20 contact each other, and the second clamping part 202 of the sixth clamping component 20 contacts the second side 103 of the sliding groove 101. At this time, the first clamping parts 201 and the second clamping parts 202 of all the clamping components 20 cannot move along the first direction any more. At this time, the first clamping parts 201 and the second clamping parts 202 of all the clamping components 20 clamp the metal raw material located between the first clamping part 201 and the second clamping part 202.

[0056] In some embodiments, the sliding groove has a first side 102 and a second side 103, and the first side 102 and the second side 103 are two sides perpendicular to the first direction. The metal sample fixing device includes two first driving components 30. One first driving component 30 is arranged on the first side 102, and the other first driving component 30 is arranged on the second side 103. Then, the connection relationship between the clamping component 20 and other components is as follows.

[0057] At this time, it is equivalent to having two clamping components 20 at the ends. One end clamping component 20 is close to the first side 102, and the other end clamping component 20 is close to the second side 103. The first clamping part 201 of the clamping component 20 close to the first side 102 is connected to the first driving component 30 arranged on the first side 102. The first clamping part 201 of the clamping component 20 close to the second side 103 is connected to the first driving component 30 arranged on the second side 103. At least two clamping components 20 are sequentially connected between the two first driving components 30.

[0058] Exemplarily, refer to Figure 7 , Figure 7The metal sample fixing device 1 shown includes two first driving components 30 and six clamping components 20. The first clamping portion 201 of the end clamping component 20 (near the first side 102) is connected to the first driving component 30. The second clamping portion 202 of the clamping component 20 at the end (near the first side 102) is connected to the first clamping portion 201 of the second clamping component 20. The second clamping portion 202 of the second clamping component 20 is connected to the first clamping portion 201 of the third clamping component 20... After connecting in sequence until the second clamping portion 202 of the fifth clamping component 20 is connected to the second clamping portion 202 of another end clamping component 20 (near the second side 103). The first clamping portion 201 of the other end clamping component 20 (near the second side 103) is connected to the second side 103 of the sliding groove 1011.

[0059] It should be noted that the labeling order of the clamping components 20 points from the first side 102 to the second side 103, and are respectively the first clamping component 20, the second clamping component 20... the sixth clamping component 20. Among them, the first clamping component 20 is the end clamping component near the first side 102, and the sixth clamping component 20 is the end clamping component near the second side 103.

[0060] Figure 7 When the shown metal sample fixing device 1 is in use, the first clamping portion 201 and the second clamping portion 202 of each clamping component 20 can be separated, and then the metal raw material to be clamped is placed between the first clamping portion 201 and the second clamping portion 202. For example, the first clamping component 20 can clamp Figure 3 the shown metal raw material, and the second clamping component 20 can clamp Figure 4 the shown metal raw material, and the third clamping component 20 can clamp Figure 5 the shown metal raw material, and the fourth clamping component 20 can clamp Figure 6 the shown metal raw material...

[0061] Figure 7 During the clamping process of the shown metal sample fixing device, the first driving component 30 provided on the first side, drives the first clamping portion 201 of the first clamping component 20 to move towards the second clamping portion 202 of the first clamping component 20. At the same time, the first driving component 30 provided on the second side 103 drives the first clamping portion 201 of the sixth clamping component 20 to move towards the second clamping portion 202 of the sixth clamping component 20.

[0062] Then, after the second clamping part 202 of the first clamping component 20 contacts the first clamping part 201 of the second clamping component 20, it drives the second clamping component 20 to move towards the third clamping component 20. At the same time, after the second clamping part 202 of the sixth clamping component 20 contacts the second clamping part 202 of the fifth clamping component 20, it drives the fifth clamping component 20 to move towards the fourth clamping component 20... until the first clamping part 201 of the third clamping component 20 contacts the second clamping part 202 of the fourth clamping component 20.

[0063] At this time, the first clamping part 201 and the second clamping part 202 of all the clamping components 20 cannot move along the first direction anymore. At this time, the first clamping part 201 and the second clamping part 202 of all the clamping components 20 clamp the metal raw material located between the first clamping part 201 and the second clamping part 202. Figure 7 The clamping process shown is equivalent to using two first driving components 30 to drive the clamping components 20 from both sides towards the middle at the same time, that is, clamping the metal raw material clamped by all the clamping components 20. Figure 7 The shown metal sample fixing device compared with Figure 1 The shown metal sample fixing device can not only improve the clamping efficiency of the metal raw material, but also enhance the clamping force of the metal raw material, making the metal raw material clamped more firmly.

[0064] The metal sample fixing device of the present application includes a bracket 10, and the bracket 10 is provided with a sliding groove 1011. At least two clamping components 20 are sequentially connected in the sliding groove 101. The clamping component 20 includes a first clamping part 201 and a second clamping part 202 which are oppositely arranged, and the first clamping part 201 can move relative to the second clamping part 202 along the first direction in the sliding groove 101. At least one driving component 30 can drive at least the first clamping part 201 of the clamping component 20 at the end to move along the length direction of the sliding groove 101 until all the clamping components 20 cannot move along the length direction of the sliding groove 101. And on the opposite sides of the first clamping part 201 and the second clamping part 202, fixing grooves 203 are provided, the fixing grooves 203 have a stepped structure, and the fixing grooves 203 include stepped parts 2031 arranged in sequence along the first direction.

[0065] The stepped portions 2031 arranged in sequence can fix metal raw materials of different shapes, and the first clamping portion 201 and the second clamping portion 202 that can move relative to each other can fix metal raw materials of different sizes. Combining the two, the metal sample preparation fixing device of the present application can clamp metal raw materials with diverse shapes and a large span of size ranges, improving the adaptability of the metal sample preparation fixing device, eliminating the need to frequently replace the metal sample preparation fixing device, thereby enhancing the consistency of the final prepared metal samples and ultimately improving the chemical analysis accuracy of the metal samples. Moreover, the metal sample preparation fixing device of the present application has at least two clamping assemblies 20, and at least one first driving assembly 30 can clamp multiple metal raw materials, so that multiple metal raw materials can be sampled simultaneously, further enhancing the consistency of the final prepared metal samples and improving the metal sample preparation efficiency at the same time.

[0066] In some embodiments, a fillet is formed at the connection between the stepped portion 2031 and the transition portion 2032. If the connection is a right angle, it is likely to cause scratches on the metal raw material. By setting the connection as a fillet, the scratches on the metal raw material can be reduced.

[0067] In some embodiments, the first driving assembly 30 may include a driving portion and a transmission portion connected to the driving portion. The transmission portion is connected to the first clamping portion 201 of the clamping assembly 20 at the end. The driving portion can be a cylinder, and the transmission portion can be a push rod. The cylinder drives the push rod to extend and retract, and one end of the push rod is connected to the first clamping portion 201 of the clamping assembly 20. The axis of the push rod is parallel to the first direction, so as to realize the movement of the first clamping portion 201 along the first direction inside the sliding groove 1011. Further, after the clamping assembly 20 at the end contacts the second clamping assembly 20, it can drive the second clamping assembly 20 to move along the first direction inside the sliding groove 1011.

[0068] It should be noted that in the embodiments of the present application, in addition to using a cylinder (pneumatic) to clamp the clamping portion, the clamping portion can also be clamped by hydraulic, electric and other means. The embodiments of the present application do not limit the driving method of the first driving assembly 30.

[0069] In some embodiments, the transmission portion is detachably connected to the first clamping portion 201 of the clamping assembly 20 at the end, and the clamping assembly 20 can be taken out from inside the sliding groove 1011. This facilitates the replacement of the clamping assembly 20, enabling the metal sample preparation fixing device to meet the sample preparation requirements of metal raw materials with more sizes and shapes.

[0070] In some embodiments, a magnetic member is provided on the first clamping portion 201, and a coil assembly is provided on the second clamping portion 202. After the coil assembly is energized, an adsorption force is generated on the magnetic member on the adjacent first clamping portion 201.

[0071] For example, Figure 1After the coil assembly in the second clamping part 202 of the first clamping assembly 20 in [[ ]] is energized, an adsorption force will be generated on the magnetic part of the first clamping part 201 of the second clamping assembly 20. Therefore, the first clamping part 201 of the second clamping assembly 20 will be adsorbed. In this way, two adjacent clamping parts are adsorbed together due to the magnetic force, further enhancing the clamping force on the metal raw material.

[0072] In some embodiments, the second clamping part 202 of the clamping assembly 20 and the first clamping part 201 of the adjacent clamping assembly 20 may also be fixedly connected.

[0073] For example, Figure 1 the second clamping part 202 of the first clamping assembly 20 in [[ ]] is fixedly connected to the first clamping part 201 of the second clamping assembly 20, and the second clamping part 202 of the second clamping assembly 20 is fixedly connected to the first clamping part 201 of the third clamping assembly 20... In this way, two adjacent clamping parts are fixedly connected together, further enhancing the clamping force on the metal raw material

[0074] The second aspect of the present application provides a metal sample preparation system.

[0075] The identification component 4 is configured to identify the state of the metal raw material fixed on the metal sample preparation fixing device 1 and send the state information of the metal raw material to the control system 5. Specifically, the identification component 4 may include a three-dimensional machine vision device. The state information that the three-dimensional machine vision device can identify the metal raw material includes but is not limited to color, structure, shape, height, position, and the number of samples. The three-dimensional machine vision device may adopt binocular vision technology.

[0076] The identification component 4 may further include a light source, a machine vision bracket, and a data communication interface.

[0077] The control system 5 is configured to control the multi-axis robotic arm to drive the processing component to process the metal raw material according to the state information. Specifically, after the control system 5 receives the state information of the metal raw material, it analyzes and processes the state information to generate a control signal. Then the control signal is sent to the drive device corresponding to the multi-axis robotic arm 2. The drive device drives the multi-axis robotic arm 2 to rotate or move according to the control signal.

[0078] The control system 5 may include a PLC (Programmable Logic Controller), a detection sensor, etc. The control system 5 can achieve data acquisition, control interaction, reading of host computer data, parameter setting, monitoring of the whole machine system, etc.

[0079] As Figure 8 shown, the multi-axis robotic arm 2 is a six-axis robotic arm. The six-axis robotic arm has six degrees of freedom and can move along the x, y, and z axes and can also rotate about the axes (roll, pitch, and yaw). Therefore, the multi-axis robotic arm 2 in the embodiment of the present application can drive the processing component 3 to move to any position of the metal raw material, realizing automatic milling sample preparation for metal raw materials of different specifications. The metal raw materials can be metal materials such as steel samples, iron samples, aluminum samples, copper samples, etc.

[0080] In some embodiments, as Figure 8 shown, the processing component 3 includes a second driving component 31 and at least two processing toolings 32. The second driving component 31 is configured to drive the at least two processing toolings 32 to process the metal raw materials clamped by at least two clamping components 20 respectively. During the milling process, the processing tooling 32 may include a processing tool head. In the embodiment of the present application, multiple groups of processing tool heads can be set, and the multiple groups of processing tool heads can process multiple metal raw materials simultaneously, thereby improving the metal sample preparation efficiency.

[0081] As Figure 8 shown, the processing tooling 32 in the embodiment of the present application may further include a purging component 33 for purging the metal raw material after processing or during processing, cleaning the debris on the metal raw material, and further improving the metal sample preparation efficiency.
