Specific embodiments

[0042] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. When the following description refers to the accompanying 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 detailed in the appended claims.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field 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.

[0044] In the prior art, due to the advantages of high hardness, high wear resistance, and good thermal conductivity, diamond is used as a key material to make diamond tools for processing. The workpieces processed by diamond tools can meet the requirements of high precision. During the production process of diamond tool blanks, the arrangement pattern of diamond particles has a crucial impact on the performance of the tools.

[0045] Currently, in traditional production methods, the arrangement spacing of diamond particles is often fixed, making it difficult to meet the diverse requirements for diamond arrangement spacing in different application scenarios. For example, in some cutting tools that require high wear resistance, a smaller arrangement spacing of diamond particles may be needed to improve cutting efficiency and wear resistance. In some grinding tools with high requirements for processing accuracy, a larger arrangement spacing may be required to ensure the uniformity and surface quality of grinding. There are many difficulties in adjusting the arrangement spacing of diamond particles. Either expensive molds need to be replaced, or the operation is complex and inefficient, restricting the production efficiency and product quality of diamond tool blanks, making it difficult to meet the diverse requirements for diamond arrangement spacing in different application scenarios and unable to meet the market demand for diverse diamond tools.

[0046] In view of this, in the embodiments of the present application, an adaptable array - type adsorption device for diamond arrangement and its usage method are provided.Figure 1 It is a schematic structural diagram of an adaptable array adsorption device for diamond arrangement provided by 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;

[0047] The array adsorption unit 3 is connected to the vacuum generator 5 through a communication 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;

[0048] 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 diamond particles;

[0049] The central control module 1 is respectively connected to the multi-axis motion platform 2, the linear motor 4, and the vacuum generator 5.

[0050] Specifically, the array adsorption unit 3 is a device for adsorbing diamond particles, which includes adsorption needle tubes 33 arranged in a matrix. The matrix arrangement includes multiple rows and multiple columns, such as 8 rows and 8 columns, etc. It should be noted that the matrix arrangement is not limited to a single matrix. For the same matrix, each row and each column are arranged regularly. In order to meet the diverse requirements of diamond arrangement spacing, the matrix arrangement may include a first matrix and a second matrix nested with each other. For example, referring to Figure 2 , Figure 2 in which double circles and single circles are used to represent the first matrix and the second matrix respectively, showing a nested matrix arrangement method, or in other embodiments, more diverse matrices are nested to form a matrix arrangement that meets the diverse requirements of arrangement spacing. For the adsorption needle tubes 33, the specifications of each adsorption needle tube 33 in the array adsorption unit 3 are the same. During the process of adsorbing diamond particles, each adsorption needle tube 33 adsorbs the corresponding diamond particle respectively. Therefore, the spacing between the adsorption needle tubes 33 is the adsorption spacing for diamond particles. Among them, 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 convenience of description, the adsorption spacing is hereinafter referred to as the spacing between the adsorption needle tubes 33.

[0051] The array adsorption unit 3 is connected to the vacuum generator 5 through a connecting pipe. The vacuum generator 5 generates negative pressure by using a positive pressure air source, and then affects the array adsorption unit 3 through this connecting pipe, that is, affects the adsorption needle tube 33, so that a negative pressure is generated at the bottom nozzle of the adsorption needle tube 33, thereby generating an adsorption force for diamond particles to perform the adsorption operation.

[0052] 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. Among them, 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. Based on these grid lines, the multi-axis motion platform 2 can locate the positions that need to perform adsorption operations or blanking operations, and drive its movement based on the fixed connection with the array adsorption unit 3. In addition, the multi-axis motion platform 2 is also provided with X-Y-Z three-axis translation and C-axis rotation linkage, so as to more flexibly drive the array adsorption unit 3 to move through 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 mover of the linear motor 4 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, realizing the adjustment of the adsorption spacing.

[0053] In addition, the central control module 1 serves as the control terminal 11 of this 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 programs for diamond particle adsorption work, and can control the multi-axis motion platform 2, the linear motor 4 and the vacuum generator 5 to execute corresponding operation steps according to this control program, so as to complete the adsorption operation of diamond particles.

[0054] The adaptable array adsorption device for diamond arrangement shown in the embodiments of the present application, by setting 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 respectively connected to the multi-axis motion platform 2 and the linear motor 4. 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 a matrix in the array adsorption unit 3. Based on this inclination angle, the distance between the adsorption needle tubes 33 changes, so as to adjust the adsorption distance for the diamond particles, and the central control module 1 controls each device. Compared with complex operations or replacing expensive molds, the present application can flexibly adjust the adsorption distance of the adsorption needle tubes 33 through the linear motor 4, so as to match the diverse requirements for the arrangement distance of diamonds, improve production adaptability and production efficiency, and reduce production costs.

[0055] In some embodiments, the array adsorption unit 3 further includes an adsorption tube rotating 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 rotating shaft 32 is vertically connected to the upper end of the adsorption needle tube 33 and penetrates 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 rotating shaft 32 forms a movable connection with the bracket 31;

[0056] The linear motor 4 is provided with a fixedly connected round rod 41. 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 a linear motion in the horizontal direction and drive the lower end of the adsorption needle tube 33 to perform a rotational motion to adjust the inclination angle.

[0057] Specifically, refer to Figure 3 , Figure 3 is a schematic structural diagram of an array adsorption unit 3 including a bracket 31, an adsorption needle tube 33, and an adsorption tube rotating shaft 32 and a linear motor 4 provided with a round rod 41. Among them, it is preset that the adsorption needle tube 33 is in a vertically downward posture. For the adsorption needle tubes 33 arranged in a matrix, each adsorption tube rotating shaft 32 is vertically connected to the upper end of the adsorption needle tubes 33 in each row (the row and column distinction can refer to the connection method shown in Figure 3 ). At the same time, there is a bracket 31 fixedly connected to the multi-axis motion platform 2. To ensure the fixing effect, it can be as shown in Figure 3As 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] In some embodiments, the top end of the adsorption syringe 33 is connected to the vacuum generator 5 through a connecting pipe, and the inner wall of the bottom end hole of the adsorption syringe 33 is arranged in a flared shape.

[0063] Specifically, referring to Figure 6 , a syringe through hole penetrating the top end and the bottom end is provided inside the adsorption syringe 33. Figure 6 The internal structure of the adsorption syringe 33 is schematically shown by a dotted line in

[0064] Its top end is connected to the vacuum generator 5 through a connecting pipe, so that the negative pressure generated by the vacuum generator 5 affects the adsorption syringe 33 through the connecting pipe, and a negative pressure for adsorption is generated at the bottom end of the adsorption syringe 33. The inner wall of the bottom end hole of the adsorption syringe 33 is arranged in a flared shape. Define the end with a smaller radius of the flared shape as the top end (referring to the vertically downward posture of the adsorption syringe 33), and further define the radius of the top end of the inner wall of the flared hole as the first radius, and the radius of the bottom end of the inner wall of the flared hole as the second radius. The first radius is smaller than the second radius. Since the adsorption syringe 33 is only used to adsorb diamond particles, in order to prevent diamond particles from entering the deep part of the hole of the adsorption syringe 33 and even affecting equipment such as the vacuum generator 5, the flared bottom end can be used to accommodate and restrict diamond particles, and generally the radius of diamond particles will be greater than the first radius, effectively preventing diamond particles from entering the deep part of the hole and improving the safety of the device and equipment.

[0065] The two-way adjustment button includes adjustment buttons for controlling two directions. When the adjustment button is triggered, it will control the mover of the linear motor 4 to move in the direction corresponding to the triggered adjustment button. The two adjustment buttons constitute the control for the mover to perform reciprocating linear motion, and based on this, it affects the adsorption syringe 33 to generate an inclination angle, supporting the realization of the scheme for adjusting the adsorption distance of the adsorption syringe 33.

[0066] It should be noted that although the adjustment button is used for manual control by the operator, the linear motor 4 still supports the automatic control of the movement of the mover under the control of the hollow control module, so that the process of adjusting the adsorption distance of diamond particles can be automated, improving the convenience and production efficiency of production.

[0067] In some embodiments, the multi-axis motion platform 2 is provided with a turntable 21. Both 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.

[0068] Specifically, referring 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 7The shown rectangle is only for reference. The linear motor 4 and the bracket 31 are both fixedly connected to the turntable 21, so as to be connected to the multi-axis motion platform 2 through the turntable 21. At the same time, the turntable 21 can perform a rotational motion 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 perform a rotational motion.

[0069] Since adjusting the adsorption distance will cause the adsorption needle tube 33 to have an inclination angle, and adsorbing diamond particles in an inclined posture may cause the movement of the diamond particles to deviate, and they cannot be accurately adsorbed into the adsorption needle tube 33, or it will be more complicated to judge the adsorption force required to adsorb diamond particles. Therefore, in this embodiment, a turntable 21 is proposed. Through the turntable 21, after the adsorption needle tube 33 has an inclination angle, it can further perform an overall rotational motion to restore the vertically downward posture. And the rotational motion generated by the turntable 21 is different from the rotational motion 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, while the turntable 21 drives the entire array adsorption unit 3 and the linear motor 4 to perform a rotational motion. In this process, the positional relationship between the adsorption needle tube 33 and the linear motor 4 will not be affected, so the adsorption distance will not be affected. The adsorption needle tube 33 can restore the vertically downward posture while maintaining the adjusted adsorption distance, so as to perform subsequent adsorption operations and improve the accuracy of the adsorption operation.

[0070] 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. The third controller 14 is connected to the vacuum generator 5 through a transmission cable.

[0071] Optionally, the central control module 1 includes a control terminal 11, a first controller 12, a second controller 13, and a third controller 14. Among them, the control terminal 11 is an industrial PC or other industrial control equipment. A control program for controlling the adsorption work of diamond particles is recorded on the control terminal 11. The first controller 12, the second controller 13, and the third controller 14 are all PLC controllers, specifically a digital operation electronic system designed for application in an industrial environment. It uses a programmable memory to store instructions for performing operations such as logical operations, sequential control, timing, counting, and arithmetic operations inside it, and controls various types of mechanical equipment or production processes through digital or analog inputs and outputs. Based on the control of the control terminal 11, it can further control other modules of the device in this embodiment, so as to complete the adsorption work. In addition, each module is connected through transmission cables. Refer toFigure 1 , specifically, 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 further connected to the multi-axis motion platform 2 through a transmission cable to control the multi-axis motion platform 2. The second controller 13 is connected to the linear motor 4 through a transmission cable to control the linear motor 4. The third controller 14 is connected to the vacuum generator 5 through a transmission cable to control the vacuum generator 5, thereby realizing the intelligent control of the diamond particle adsorption work and improving the production efficiency.

[0072] Please refer to Figure 8 , the embodiment of the present application further provides a usage method of an adaptable array adsorption device for diamond arrangement. The usage method is applied to the adaptable array adsorption device for diamond arrangement described in any of the above embodiments. The usage method includes:

[0073] Step S100, input the particle parameters, adsorption position, and feeding position of diamond particles through the central control module 1;

[0074] Step S200, control the array adsorption unit 3 to move to the adsorption position through the multi-axis motion platform 2, and adjust the adsorption spacing of the adsorption needle tubes 33 in the array adsorption unit 3 to the target arrangement spacing through the linear motor 4. The particle parameters include the target arrangement spacing;

[0075] Step S300, adjust the adsorption force through the vacuum generator 5 so that the adsorption needle tubes 33 perform the adsorption operation on diamond particles;

[0076] Step S400, control the array adsorption unit 3 to move to the feeding position through the multi-axis motion platform 2 and perform the feeding operation at the feeding position.

[0077] For the adsorption work of diamond particles, it includes two operations: adsorbing diamond particles at the adsorption position and feeding at the feeding position. Before starting the adsorption work, the staff needs to first input the particle parameters, adsorption position, and feeding position of diamond particles through the central control module 1. The particle parameters include particle size and target arrangement spacing. Among them, the particle size is the size of the diamond particles that need to be adsorbed currently. The particle size affects the adsorption force that the vacuum generator 5 needs to generate. The target arrangement spacing is the spacing required for the diamond tool to be made 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 relevant parameters, which are not limited herein.

[0078] After inputting the data of the particle parameters, adsorption position, and blanking position, the adsorption work is controlled to start. The central control module 1 begins to control the multi-axis motion platform 2, linear motor 4, and vacuum generator 5. Through the four-axis linkage control of the multi-axis motion platform 2, the array-type adsorption unit 3 is moved to the adsorption position. Then, the linear motor 4 is used to adjust the adsorption spacing of the adsorption needle tubes 33 in the array-type adsorption unit 3 to match the target arrangement spacing. Next, the vacuum generator 5 is started, and the adsorption force is adjusted through the vacuum generator 5 so that the adsorption force is sufficient to adsorb the diamond particles of this particle size. When the diamond particles are adsorbed, the array-type adsorption unit 3 is again controlled by the multi-axis motion platform 2 to move to the blanking position for blanking operation, thus ending the adjustment of the arrangement spacing and adsorption work for the diamond particles.

[0079] Through the solution of this embodiment, the adsorption work for diamond particles can be intelligently and automatically completed after inputting the particle parameters, adsorption position, and blanking position, without the need for additional complex manual operation to adjust the arrangement spacing, improving production efficiency.

[0080] In some embodiments, the step of adjusting the adsorption spacing of the array-type adsorption unit 3 to the target arrangement spacing includes:

[0081] Determine the target moving distance according to the preset spacing, target arrangement spacing, and preset height. 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 support 31;

[0082] Control the mover of the linear motor 4 to move the target moving distance so that the adsorption spacing matches the target arrangement spacing.

[0083] Combined with the above embodiments, it can be understood that when the mover of the linear motor 4 moves, the adsorption spacing will change. Because in order to make the adsorption spacing match 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 moving distance. Specifically, referring to Figure 5 , define the moving distance of the mover as x, and the height difference between the horizontal plane of the linear motor 4 and the horizontal plane of the support 31 as the preset height h. Then, combined with the target arrangement distance and the preset spacing , according to trigonometric functions, the inclination angle can be determined by the following formula (1):

[0084] (1)

[0085] And the target moving distance x can be determined according to the following formula (2):

[0086] (2)

[0087] After determining the target moving distance in this way, the mover of the linear motor 4 can be controlled to move, so as to accurately control the adsorption distance to change to match the target arrangement distance.

[0088] In addition, it should be noted that the above calculation process is based on the scenario where the mover is at the initial position, that is, the adsorption needle tube 33 has no inclination angle when adjusting the adsorption distance. If the mover is not at the initial position, that is, the adsorption needle tube 33 already has an inclination angle before adjustment, the distance between the mover and its initial position before adjustment needs to be additionally calculated to calculate the accurate target moving distance.

[0089] By calculating the target moving distance according to the preset distance, the target arrangement distance and the preset height, and then controlling the mover of the linear motor 4 to move according to the target moving distance, the adjustment of the adsorption distance can be completed, so as to support the intelligent automation to complete the adsorption work of diamond particles and improve the production efficiency.

[0090] In some embodiments, the bottom end of the adsorption needle tube 33 is set to be trumpet-shaped, and the steps of adjusting the adsorption force include:

[0091] Obtain the first radius and the second radius of the bottom end of the trumpet-shaped adsorption needle tube 33, the second radius is greater than the first radius, and the second radius is less than 2 times the first radius;

[0092] Determine the target adsorption force according to the particle size, the first radius, the second radius and the preset conditions, and adjust the adsorption force to the target adsorption force.

[0093] 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 end of the adsorption needle tube 33 is designed such that the second radius is greater than the first radius. And in order to ensure that each adsorption needle tube 33 adsorbs only one diamond particle, the second radius is less than 2 times the first radius. Refer to Figure 6 , define the second radius as , and the first radius as . In addition, define the particle size as (that is, the radius of the diamond particle), and the preset condition is to judge the size relationship between the particle size and the second radius and the first radius. Since in order to prevent the diamond particle from entering the deep part of the tube hole of the adsorption needle tube 33 and affecting the equipment safety, generally the first radius is designed to be less than the particle size. It is only necessary to judge the size relationship between the particle size and the second radius, which affects whether the diamond particle can be received into the structure of the inner wall of the trumpet-shaped tube hole when being adsorbed, and thus affects the judgment of the required adsorption force. Therefore, the preset condition determines the applicable different adsorption force calculation formulas by judging the size relationship between the particle size and the second radius.

[0094] In addition, it should be noted that the negative pressure generated by the vacuum generator 5 manifests as an adsorption pressure at the bottom end of the adsorption needle tube 33. The adsorption pressure combines 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:

[0095] (3)

[0096] (4)

[0097] Among them, is the target adsorption force. At the same time, is the corresponding required adsorption pressure. For the adsorption pressure, in order to adsorb diamond particles, the adsorption pressure needs to overcome the gravity of the diamond particles. Therefore, combining 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:

[0098] (5)

[0099] Combined with the second radius , the first radius and the particle size , the following formulas (6) and (7) are used to determine the required adsorption pressure in formulas (3) and (4) :

[0100] (6)

[0101] (7)

[0102] Based on the above formulas (3), (4), (6), and (7), the adsorption pressure required to adsorb diamond particles during the adsorption operation can be determined, and the vacuum generator 5 is controlled to generate the corresponding adsorption pressure, so that a corresponding adsorption force is generated at the bottom end of the adsorption needle tube 33, completing the work of adsorbing diamond particles. This process also realizes intelligent automation through the calculation of this embodiment, improving production efficiency.

[0103] In some embodiments, the multi-axis motion platform 2 is provided with a turntable 21. Before the step of adjusting the adsorption force through the vacuum generator 5 to enable the array type adsorption unit 3 to perform the adsorption operation on diamond particles, it further includes:

[0104] Determine the compensation angle according to the preset spacing and the target arrangement spacing;

[0105] Control the turntable 21 to rotate the compensation angle so that the adsorption needle tube 33 resumes a vertically downward posture.

[0106] As described in the above embodiments, when the adsorption syringe 33 adsorbs diamond particles in an inclined posture, it may cause deviation in the movement of the diamond particles, and they cannot be accurately adsorbed into the adsorption syringe 33, or it may be more complicated to determine the adsorption force required to adsorb diamond particles. Therefore, optionally, before generating the adsorption force for the adsorption operation, first make the adsorption syringe 33 return to the vertically downward posture. Refer to 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 syringe 33 can be made to return to the vertically downward posture. To this end, the rotation angle of the turntable 21 needs to be determined, and this angle is defined as the compensation angle.

[0107] Specifically, refer to Figure 9 , according to the preset spacing and the target arrangement spacing , the compensation angle can be determined by the following formula (8) :

[0108] (8)

[0109] By controlling the turntable 21 to rotate by the compensation angle , the adsorption syringe 33 is made to return to the vertically downward posture, improving the accuracy of the adsorption operation.

[0110] In some embodiments, considering the complexity of the adsorption working scenario, there may also be a need for the adsorption operation to be carried out with the adsorption syringe 33 in an inclined posture. Refer to Figure 10 , for this scenario, this embodiment also proposes a pressure correction coefficient , this pressure correction coefficient is a coefficient greater than 1, and its value can be preset or determined according to the inclination angle. Combining this pressure correction coefficient and the above formulas (6) and (7), there are the following formulas (9) and (10) for determining the corrected adsorption pressure in the inclined posture :

[0111] (9)

[0112] (10)

[0113] By correcting the adsorption pressure, the target adsorption force determined by the adsorption syringe 33 in the inclined posture is made more accurate, improving the accuracy of the adsorption operation.
