DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the embodiments of the present application. They are only examples of devices and methods consistent with some aspects of the embodiments of the present application as detailed in the attached claims.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0021] In the prior art, diamond is used as a key material to make diamond tools for machining due to its advantages such as high hardness, high wear resistance and good thermal conductivity. The workpieces machined by diamond tools can meet the requirements of high precision. In the production process of diamond tool blanks, the arrangement of diamond particles has a crucial impact on the performance of the tool.

[0022] At present, the spacing of diamond particles in traditional production methods is often fixed, which makes it difficult to meet the diverse requirements for diamond spacing in different application scenarios. For example, in some cutting tools that require high wear resistance, a smaller spacing of diamond particles may be required to improve cutting efficiency and wear resistance, while in some grinding tools that require high processing accuracy, a larger spacing may be required to ensure grinding uniformity and surface quality. There are many difficulties in adjusting the spacing of diamond particles. Either expensive molds need to be replaced, or the operation is complicated and inefficient, which restricts the production efficiency and product quality of diamond tool blanks. It is difficult to meet the diverse requirements for diamond spacing in different application scenarios, and it is also impossible to meet the market demand for diversified diamond tools.

[0023] In view of this, an adaptable array adsorption device for diamond arrangement and a method of use are provided in the embodiments of the present application. Figure 1is a schematic diagram of the structure of an adaptable array adsorption device for diamond arrangement provided in an embodiment of the present application, Figure 1 The device in the figure may include but is not limited to the structure shown in the figure. Specifically, the device includes: an array adsorption unit 3, a vacuum generator 5, a multi-axis motion platform 2, a linear motor 4 and a central control module 1; The array adsorption unit 3 is connected to the vacuum generator 5 through a connecting pipe. The array adsorption unit 3 is also fixedly connected to the multi-axis motion platform 2 and movably connected to the linear motor 4. The linear motor 4 is connected to the multi-axis motion platform 2. The surface of the multi-axis motion platform 2 is provided with grid lines for positioning. The multi-axis motion platform 2 is used to drive the array adsorption unit 3 to move through four-axis linkage. The array adsorption unit 3 includes adsorption needle tubes 33 arranged in a matrix. The linear motor 4 is used to adjust the inclination angle of the adsorption needle tubes 33 to adjust the adsorption spacing of the adsorption needle tubes 33 for the diamond particles. The central control module 1 is connected to the multi-axis motion platform 2, the linear motor 4 and the vacuum generator 5 respectively.

[0024] Specifically, the array adsorption unit 3 is a device for adsorbing diamond particles, which includes adsorption needles 33 arranged in a matrix, and the matrix arrangement includes multiple rows and columns, such as 8 rows and 8 columns. It should be noted that the matrix arrangement is not limited to one matrix. Since for the same matrix, each row and each column are arranged regularly, in order to meet the diverse requirements of the diamond arrangement spacing, the matrix arrangement may include a first matrix and a second matrix nested with each other, such as reference Figure 2 , Figure 2 In the figure, a double circle and a single circle represent the first matrix and the second matrix respectively, which illustrates a mutually nested matrix arrangement, or in other embodiments, a more diverse matrix is ​​nested, so as to form a matrix arrangement that meets the diversified arrangement spacing requirements. As for the adsorption needle tubes 33, the specifications of each adsorption needle tube 33 in the array adsorption unit 3 are the same. In the process of adsorbing diamond particles, each adsorption needle tube 33 adsorbs the corresponding diamond particles respectively. Therefore, the spacing between the adsorption needle tubes 33 is the adsorption spacing for the diamond particles, wherein the distance between the centers of the needle tube through holes of two adjacent adsorption needle tubes 33 is defined as the spacing between the adsorption needle tubes 33. For the sake of convenience, the adsorption spacing is used below to refer to the spacing between the adsorption needle tubes 33.

[0025] The array adsorption unit 3 is connected to the vacuum generator 5 through a connecting tube. The vacuum generator 5 generates negative pressure by utilizing a positive pressure gas source, and then affects the array adsorption unit 3, that is, the adsorption needle tube 33 through the connecting tube, so that negative pressure is generated at the bottom end of the adsorption needle tube 33, thereby generating an adsorption force for the diamond particles and performing an adsorption operation.

[0026] On the other hand, the array adsorption unit 3 is also fixedly connected to the multi-axis motion platform 2 and movably connected to the linear motor 4, wherein the linear motor 4 is connected to the multi-axis motion platform 2, and the surface of the multi-axis motion platform 2 is provided with grid lines for positioning. Based on the grid lines, the multi-axis motion platform 2 can locate the position where the adsorption operation or the material unloading operation is required, and drive it to move based on the fixed connection with the array adsorption unit 3. In addition, the multi-axis motion platform 2 is also provided with XYZ three-axis translation and C-axis rotation linkage, so as to more flexibly drive the array adsorption unit 3 to move through the four-axis linkage. The linear motor 4 is a device that converts electrical energy into linear motion mechanical energy. The linear motor 4 is actually movably connected to the adsorption needle tube 33. Based on this, the linear motion of the linear motor 4 mover can drive one end of the adsorption needle tube 33 to move. At the same time, because the array adsorption unit 3 is fixedly connected to the multi-axis motion platform 2, the adsorption needle tube 33 will eventually tilt and have an inclination angle, so that the adsorption spacing of the adsorption needle tube 33 changes, and the adjustment of the adsorption spacing is achieved.

[0027] In addition, the central control module 1 serves as the control terminal 11 of the device, and is respectively connected to the multi-axis motion platform 2, the linear motor 4 and the vacuum generator 5. The central control module 1 records the relevant control program for the diamond particle adsorption work. The multi-axis motion platform 2, the linear motor 4 and the vacuum generator 5 can be controlled according to the control program to perform corresponding operation steps, thereby completing the adsorption operation of the diamond particles.

[0028] The adaptive array adsorption device for diamond arrangement shown in the embodiment of the present application is provided with an array adsorption unit 3, a vacuum generator 5, a multi-axis motion platform 2, a linear motor 4 and a central control module 1. The array adsorption unit 3 is connected to the vacuum generator 5 through a connecting pipe, so that the array adsorption unit 3 generates an adsorption force to adsorb diamond particles. The array adsorption unit 3 is connected to the multi-axis motion platform 2 and the linear motor 4 respectively. The multi-axis motion platform 2 drives the array adsorption unit 3 to move to the adsorption position of the diamond particles through grid lines and four-axis linkage. The linear motor 4 can adjust the inclination angle of the adsorption needle tubes 33 arranged in the matrix in the array adsorption unit 3. Based on the inclination angle, the spacing of the adsorption needle tubes 33 changes, thereby adjusting the adsorption spacing for the diamond particles, and the central control module 1 controls each device. Compared with complex operations or replacement of expensive molds, the present application can flexibly adjust the adsorption spacing of the adsorption needle tubes 33 through the linear motor 4, thereby matching the diversified requirements for the diamond arrangement spacing, improving production adaptability and production efficiency, and reducing production costs.

[0029] In some embodiments, the array adsorption unit 3 further includes an adsorption tube shaft 32 and a bracket 31, the bracket 31 is fixedly connected to the multi-axis motion platform 2, the bracket 31 is provided with a through hole, the adsorption tube shaft 32 is vertically connected to the upper end of the adsorption needle tube 33 and passes through the through hole, the adsorption needle tube 33 is fixedly connected to the multi-axis motion platform 2 through the bracket 31, and the adsorption tube shaft 32 is movably connected to the bracket 31; The linear motor 4 is provided with a fixedly connected round rod 41, and the lower end of the adsorption needle tube 33 forms a tangential movable connection with the round rod 41. The linear motor 4 is used to move the round rod 41 through horizontal linear motion, and drive the lower end of the adsorption needle tube 33 to rotate through the round rod 41 to adjust the inclination angle.

[0030] Specifically, refer to Figure 3 , Figure 3 FIG. 1 is a structural diagram of an array adsorption unit 3 including a bracket 31, adsorption needle tubes 33 and adsorption tube rotating shafts 32, and a linear motor 4 provided with a round rod 41, wherein the adsorption needle tubes 33 are preset to be in a vertical downward posture, and for the adsorption needle tubes 33 arranged in a matrix, each adsorption tube rotating shaft 32 is vertically connected to the upper end of each row of adsorption needle tubes 33 (the distinction between rows and columns can be referred to Figure 3 At the same time, the bracket 31 is fixedly connected to the multi-axis motion platform 2. In order to ensure the fixing effect, it can be as follows Figure 3 As shown, brackets 31 are provided on both opposite sides, or only on one side, and a through hole corresponding to the adsorption tube shaft 32 is provided on the bracket 31. The adsorption tube shaft 32 passes through the through hole to form a movable connection with the bracket 31, and the adsorption tube shaft 32 can rotate in the through hole. Based on the connection relationship between the adsorption needle tube 33, the adsorption tube shaft 32 and the bracket 31, the adsorption needle tube 33 is fixedly connected to the multi-axis motion platform 2, and at the same time, the adsorption needle tube 33 can rotate around the connection point between it and the adsorption tube shaft 32.

[0031] On the other hand, the mover of the linear motor 4 is provided with a fixedly connected round rod 41, and each round rod 41 forms a tangential movable connection with the lower end of each row of adsorption needle tubes 33. This movable connection enables the movement of the round rod 41 to drive the lower end of the adsorption needle tube 33 to move, and at the same time, the connection angle between the round rod 41 and the adsorption needle tube 33 can change. Therefore, when the mover of the linear motor 4 moves horizontally, the round rod 41 also moves horizontally, which is equivalent to moving the lower end of the adsorption needle tube 33, while the upper end of the adsorption needle tube 33 cannot move horizontally due to the fixed connection with the bracket 31, but combined with the through hole on the bracket 31 and the adsorption tube shaft 32, the adsorption needle tube 33 can rotate, that is, the inclination angle changes, refer to Figure 4 , Figure 4 The posture of the adsorption needle tube 33 changes under the action of the linear motor 4, resulting in a schematic diagram of the inclination angle.

[0032] For further reference, Figure 5 , Figure 5 In order to abstract the vertical downward posture and the inclined posture of the adsorption needle tube 33 into lines for illustration, it is defined that when the adsorption needle tube 33 is in the vertical downward posture, the adsorption spacing is the preset spacing L, and when the adsorption needle tube 33 is in the inclined posture, the adsorption spacing is changed to D, and the inclination angle is also defined as , combined with Figure 5 The relationship between D and L can be shown as Therefore, when the adsorption needle tube 33 has an inclination angle, the adsorption spacing is changed, achieving the effect of adjusting the adsorption spacing.

[0033] In other embodiments, the linear motion of the mover of the linear motor 4 can be converted into the rotational motion of the adsorption needle tube 33 by combining with structures such as gear transmission or crank connecting rod.

[0034] In this embodiment, structures such as the adsorption tube rotating shaft 32 and the round rod 41 are provided, so that the adsorption needle tube 33 can be controlled to rotate through the linear motion of the linear motor 4, thereby adjusting the adsorption spacing at an inclination angle, improving production adaptability and production efficiency, and eliminating the need for complicated operations or mold replacement, thereby reducing the cost required to adjust the adsorption spacing and reducing production costs.

[0035] In some embodiments, the top end of the adsorption needle tube 33 is connected to the vacuum generator 5 through a connecting tube, and the inner wall of the tube hole at the bottom end of the adsorption needle tube 33 is configured to be trumpet-shaped.

[0036] Specifically, refer to Figure 6 The adsorption needle tube 33 is provided with a needle tube through hole penetrating the top and bottom ends. Figure 6 The internal structure of the adsorption needle tube 33 is indicated by a dotted line, and its top end is connected to the vacuum generator 5 through a connecting tube, so that the negative pressure generated by the vacuum generator 5 affects the adsorption needle tube 33 through the connecting tube, and generates a negative pressure for adsorption at the bottom end of the adsorption needle tube 33. The inner wall of the tube hole at the bottom end of the adsorption needle tube 33 is set to be trumpet-shaped, and the end with a smaller radius of the trumpet is defined as the top end (refer to the vertical downward posture of the adsorption needle tube 33), and the radius of the top end of the trumpet-shaped tube hole inner wall is further defined as the first radius, and the radius of the bottom end of the trumpet-shaped tube hole inner wall is defined as the second radius, and the first radius is smaller than the second radius. Since the adsorption needle tube 33 is only used to adsorb diamond particles, in order to prevent diamond particles from entering the deep part of the tube hole of the adsorption needle tube 33 and even affecting the vacuum generator 5 and other equipment, the trumpet-shaped bottom end can be used to accommodate and limit the diamond particles, and the radius of the diamond particles is generally greater than the first radius, which effectively prevents the diamond particles from entering the deep part of the tube hole and improves the safety of the device.

[0037] In some embodiments, the linear motor 4 is provided with a bidirectional adjustment button, and the bidirectional adjustment button is used to control the mover of the linear motor 4 to perform linear motion in the horizontal direction.

[0038] The bidirectional adjustment button includes adjustment buttons for controlling two directions. When the adjustment button is triggered, the mover of the linear motor 4 will be controlled to move in the direction corresponding to the triggered adjustment button. The two adjustment buttons constitute the control of the mover's reciprocating linear motion, and based on this, it affects the inclination angle of the adsorption needle tube 33, and supports the implementation of the solution for adjusting the adsorption spacing of the adsorption needle tube 33.

[0039] It should be noted that although the adjustment button is used for manual control by the staff, the linear motor 4 still supports automatic control of the movement of the mover under the control of the hollow control module, so that the process of adjusting the adsorption spacing of diamond particles can be automated, improving the convenience and efficiency of production.

[0040] In some embodiments, the multi-axis motion platform 2 is provided with a turntable 21, and the linear motor 4 and the bracket 31 are fixedly connected to the turntable 21, and the turntable 21 is used to drive the linear motor 4 and the array adsorption unit 3 to perform rotational motion.

[0041] Specifically, refer to Figure 7 The multi-axis motion platform 2 is provided with a turntable 21, and the shape of the turntable 21 is not limited. Figure 7 The rectangle shown is for reference only, and the linear motor 4 and the bracket 31 are both fixedly connected to the turntable 21, and thus connected to the multi-axis motion platform 2 through the turntable 21. At the same time, the turntable 21 can rotate under the control of the multi-axis motion platform 2, thereby driving the entire structure of the fixedly connected array adsorption unit 3 and the linear motor 4 to rotate.

[0042] Since adjusting the adsorption spacing will cause the adsorption needle tube 33 to have an inclination angle, and adsorbing diamond particles in an inclined posture may cause deviations in the movement of the diamond particles, making it impossible to accurately adsorb them into the adsorption needle tube 33, or making it more complicated to judge the adsorption force required for adsorbing diamond particles, a turntable 21 is proposed in this embodiment. Through the turntable 21, the adsorption needle tube 33 can further perform an overall rotational movement after the inclination angle appears, and restore the vertical downward posture. The rotational movement generated by the turntable 21 is different from the rotational movement generated by the linear motor 4. The linear motor 4 only affects the lower end of the adsorption needle tube 33, and its upper end is fixed. The turntable 21 drives the entire array adsorption unit 3 and the linear motor 4 to rotate. In this process, the positional relationship between the adsorption needle tube 33 and the linear motor 4 will not be affected, so the adsorption spacing will not be affected. The adsorption needle tube 33 can restore the vertical downward posture while maintaining the adjusted adsorption spacing, thereby performing subsequent adsorption operations and improving the accuracy of the adsorption operation.

[0043] In some embodiments, the central control module 1 includes a control terminal 11, a first controller 12, a second controller 13 and a third controller 14. The control terminal 11 is connected to the first controller 12, the second controller 13 and the third controller 14 respectively through transmission cables, the first controller 12 is connected to the multi-axis motion platform 2 through a transmission cable, the second controller 13 is connected to the linear motor 4 through a transmission cable, and the third controller 14 is connected to the vacuum generator 5 through a transmission cable.

[0044] Optionally, the central control module 1 includes a control terminal 11, a first controller 12, a second controller 13 and a third controller 14, wherein the control terminal 11 is an industrial PC or other industrial control equipment, and the control terminal 11 records a control program for controlling the adsorption of diamond particles. The first controller 12, the second controller 13 and the third controller 14 are all PLC controllers, which are specifically digital operation electronic systems designed for use in industrial environments. They use a programmable memory to store instructions for performing logical operations, sequential control, timing, counting and arithmetic operations, etc., and control various types of mechanical equipment or production processes through digital or analog input and output. Based on the control of the control terminal 11, other modules of the device of this embodiment can be further controlled to complete the adsorption work. In addition, each module is connected separately by a transmission cable, referring to Figure 1Specifically, the control terminal 11 is connected to the first controller 12, the second controller 13 and the third controller 14 through transmission cables, and the first controller 12 is connected to the multi-axis motion platform 2 through the transmission cable to control the multi-axis motion platform 2, the second controller 13 is connected to the linear motor 4 through the transmission cable to control the linear motor 4, and the third controller 14 is connected to the vacuum generator 5 through the transmission cable to control the vacuum generator 5, thereby realizing intelligent control of the diamond particle adsorption work and improving production efficiency.

[0045] See also Figure 8 The present application also provides a method for using an adaptable array adsorption device for diamond arrangement, the method for using the adaptable array adsorption device for diamond arrangement as described in any of the above embodiments, and the method for using the adaptable array adsorption device for diamond arrangement includes: Step S100, inputting the particle parameters, adsorption position and feeding position of diamond particles through the central control module 1; Step S200, controlling the array adsorption unit 3 to move to the adsorption position through the multi-axis motion platform 2, and adjusting the adsorption spacing of the adsorption needles 33 in the array adsorption unit 3 to the target arrangement spacing through the linear motor 4, and the particle parameters include the target arrangement spacing; Step S300, adjusting the adsorption force through the vacuum generator 5 so that the adsorption needle tube 33 performs an adsorption operation on the diamond particles; Step S400, controlling the array adsorption unit 3 to move to the unloading position through the multi-axis motion platform 2, and performing unloading operation at the unloading position.

[0046] The adsorption of diamond particles includes two operations: adsorption of diamond particles at the adsorption position and unloading at the unloading position. Before starting the adsorption work, the staff needs to input the particle parameters, adsorption position and unloading position of the diamond particles through the central control module 1, wherein the particle parameters include particle size and target arrangement spacing, wherein the particle size is the size of the diamond particles currently required to be adsorbed, and the particle size affects the vacuum generator 5 to determine the adsorption force to be generated, and the target arrangement spacing is the spacing required for the manufactured diamond tool, and is also the adsorption spacing that needs to be set in the subsequent adsorption work. In other embodiments, the particle parameters may also include other related parameters, which are not limited here.

[0047] After inputting the data of particle parameters, adsorption position and unloading position, the control starts the adsorption work, and the central control module 1 starts to control the multi-axis motion platform 2, the linear motor 4 and the vacuum generator 5. The array adsorption unit 3 is moved to the adsorption position through the four-axis linkage control of the multi-axis motion platform 2, and then the adsorption spacing of the adsorption needle tubes 33 in the array adsorption unit 3 is adjusted through the linear motor 4 to match the target arrangement spacing, and then the vacuum generator 5 is started, and the adsorption force is adjusted through the vacuum generator 5 to make the adsorption force sufficient to adsorb the diamond particles of the particle size. After the diamond particles are adsorbed, the array adsorption unit 3 is controlled to move to the unloading position through the multi-axis motion platform 2 again to perform the unloading operation, thereby completing the arrangement spacing adjustment and adsorption work for the diamond particles.

[0048] Through the scheme of this embodiment, the adsorption of diamond particles can be completed intelligently and automatically after inputting particle parameters, adsorption position and feeding position, without the need for additional complex manual operations to adjust the arrangement spacing, thereby improving production efficiency.

[0049] In some embodiments, the step of adjusting the adsorption spacing of the array adsorption unit 3 to the target arrangement spacing includes: The target moving distance is determined according to the preset spacing, the target arrangement spacing and the preset height, wherein the preset spacing is the initial spacing between adjacent adsorption needle tubes 33, and the preset height is the height difference between the horizontal plane of the linear motor 4 and the horizontal plane of the bracket 31; The mover of the linear motor 4 is controlled to move the target moving distance so that the adsorption spacing matches the target arrangement spacing.

[0050] It can be understood from the above embodiments that when the mover of the linear motor 4 moves, the adsorption spacing will change. In order to match the adsorption spacing with the target arrangement spacing, it is necessary to calculate the distance that the mover needs to move based on the target arrangement spacing, that is, the target movement distance. Figure 5 , define the moving distance of the mover as x, the height difference between the horizontal plane of the linear motor 4 and the horizontal plane of the bracket 31 as the preset height h, then combine the target arrangement distance and preset spacing According to trigonometric functions, the inclination angle can be determined by the following formula (1): : (1) And the target moving distance x is determined according to the following formula (2): (2) In this way, after determining the target moving distance, the mover of the linear motor 4 can be controlled to move, thereby accurately controlling the adsorption spacing to match the target arrangement spacing.

[0051] In addition, it should be noted that the above calculation process is based on the scenario where the mover is in the initial position, that is, the adsorption distance is adjusted when the adsorption needle 33 has not yet appeared in the tilt angle. If the mover is no longer in the initial position, that is, the adsorption needle 33 already has a tilt angle before the adjustment, it is necessary to additionally calculate the distance between the mover and its initial position before adjustment, so as to calculate the accurate target moving distance.

[0052] By calculating the target moving distance according to the preset spacing, target arrangement spacing and preset height, the adjustment of the adsorption spacing can be completed by controlling the movement of the linear motor 4 according to the target moving distance, thereby supporting intelligent automation to complete the adsorption of diamond particles and improve production efficiency.

[0053] In some embodiments, the bottom end of the adsorption needle tube 33 is configured to be trumpet-shaped, and the step of adjusting the adsorption force includes: Obtain a first radius and a second radius of the bottom end of the trumpet-shaped adsorption needle tube 33, wherein the second radius is greater than the first radius and is less than 2 times the first radius; The target adsorption force is determined according to the particle size, the first radius, the second radius and preset conditions, and the adsorption force is adjusted to the target adsorption force.

[0054] According to the adsorption requirements of the adsorption needle tube 33 for diamond particles, the inner wall of the trumpet-shaped tube hole at the bottom of the adsorption needle tube 33 is designed to have a second radius greater than the first radius, and in order to ensure that each adsorption needle tube 33 only adsorbs one diamond particle, the second radius is less than 2 times the first radius, referring to Figure 6 , define the second radius as , the first radius is In addition, the particle size is defined as (i.e., the radius of the diamond particles), the preset condition is to judge the size of the particle size, the second radius, and the first radius. In order to prevent the diamond particles from entering the deep hole of the adsorption needle tube 33 and affecting the safety of the equipment, the first radius is generally designed to be smaller than the particle size. The particle size and the second radius can be judged. This affects whether the diamond particles can be accommodated in the structure of the inner wall of the trumpet-shaped hole when being adsorbed, thereby affecting the judgment of the required adsorption force. Therefore, the preset condition determines the application of different adsorption force calculation formulas by judging the particle size and the second radius.

[0055] In addition, it should be noted that the negative pressure generated by the vacuum generator 5 is manifested as adsorption pressure at the bottom end of the adsorption needle tube 33. The adsorption pressure is combined with the structure of the inner wall of the trumpet-shaped tube hole to form an adsorption force. For diamond particles of different particle sizes, the following formulas (3) and (4) are used to determine the relationship between the target adsorption force, particle size and adsorption pressure: (3) (4) in, is the target adsorption force, and To correspond to the required adsorption pressure, in order to adsorb the diamond particles, the adsorption pressure needs to overcome the gravity of the diamond particles, so combined with the density of the diamond particles , the acceleration due to gravity , the following formula (5) is used to confirm the gravity of a single diamond particle: (5) Combined with the second radius , the first radius and particle size , the following formula (6) (7) is used to determine the adsorption pressure required in formula (3) (4) : (6) (7) Based on the above formulas (3), (4), (6), and (7), the adsorption pressure required for adsorbing diamond particles in the adsorption operation can be determined, and the vacuum generator 5 can be controlled to generate the corresponding adsorption pressure, so that the bottom end of the adsorption needle tube 33 generates a corresponding adsorption force to complete the work of adsorbing diamond particles. This process also realizes intelligent automation through the calculation of this embodiment, thereby improving production efficiency.

[0056] In some embodiments, the multi-axis motion platform 2 is provided with a turntable 21, and before the step of adjusting the adsorption force by the vacuum generator 5 so that the array adsorption unit 3 performs the adsorption operation on the diamond particles, the method further includes: Determine the compensation angle according to the preset spacing and the target arrangement spacing; The control dial 21 is rotated by a compensation angle so that the adsorption needle tube 33 returns to a vertical downward posture.

[0057] Referring to the above embodiment, when the adsorption needle tube 33 in an inclined posture adsorbs diamond particles, the movement of the diamond particles may be deviated, and the diamond particles cannot be accurately adsorbed into the adsorption needle tube 33, or it may make it more complicated to judge the adsorption force required for adsorbing the diamond particles. Therefore, before generating the adsorption force for the adsorption operation, the adsorption needle tube 33 may be restored to a vertical downward posture. Figure 7 By controlling the turntable 21 to drive the array adsorption unit 3 and the linear motor 4 to rotate as a whole, the adsorption needle tube 33 can be restored to a vertical downward posture. For this purpose, it is necessary to determine the rotation angle of the turntable 21, which is defined as the compensation angle.

[0058] Specifically, refer to Fig. 9 , according to the preset spacing and target alignment spacing , the compensation angle can be determined by the following formula (8): : (8) The compensation angle is rotated by controlling the turntable 21 , so that the adsorption needle tube 33 returns to a vertically downward posture, improving the accuracy of the adsorption operation.

[0059] In some embodiments, considering the complexity of the adsorption working scene, there may be a need for the adsorption operation to be performed with the adsorption needle 33 in an inclined posture. Fig.10 For this scenario, this embodiment also proposes a pressure correction coefficient , the pressure correction factor is a coefficient greater than 1, whose value can be preset or determined according to the inclination angle, combined with the pressure correction coefficient And the above equations (6) and (7), the following equations (9) and (10) are used to determine the corrected adsorption pressure under tilted posture : (9) (10) By correcting the adsorption pressure, the target adsorption force determined by the adsorption needle tube 33 in the inclined posture is made more accurate, thereby improving the accuracy of the adsorption operation.
