Description

Technical Field

[0001] This application relates to the field of processing and production technology, and more specifically, to a transport tooling plate. Background Technology

[0002] In the field of packaging production technology (such as chip packaging, electronic component packaging, etc.), the significance of packaging is to place, fix, seal, protect the chip and enhance its electrothermal performance, that is, to provide strong heat dissipation and electromagnetic shielding, thereby protecting the chip from the influence of the surrounding environment. In order to shorten the interval between packaging processes and improve production efficiency, major companies often design special tooling boards for transporting packaged components (such as chip packaging or electronic component packaging) between them.

[0003] Although existing tooling boards have multiple areas for placing packaged components (such as chip packages or electronic component packages), the placement of packaged components on current transport tooling boards is all done manually, which results in low efficiency. Utility Model Content

[0004] The purpose of this application is to provide a transport tooling plate to solve the problem of low efficiency caused by the fact that the placement of encapsulated parts on the transport tooling plate is currently done manually.

[0005] In a first aspect, this utility model provides a transport tooling plate, comprising: a base plate and a cover plate; a placement area is provided on the base plate, the placement area including at least one placement position, each placement position being used to place a target package; the cover plate is placed on the base plate, the cover plate being used to limit and fix the target package in the placement area; a reference element, feature holes, and feature grooves are distributed on the base plate; wherein the centroids of the reference element, feature holes, and feature grooves are distributed at different spatial positions, and the reference element, feature holes, and feature grooves are located outside the placement area.

[0006] The above-designed transport fixture plate uses a placement area on its base plate to place the target package. Positioning is achieved by setting reference parts, feature holes, and feature slots with their centroids distributed at different spatial locations around the placement area. For example, three-coordinate positioning is used to improve production accuracy. Furthermore, based on three-coordinate positioning and dedicated placement equipment, the placement of the target package can be automated, significantly improving the degree of automation. This increases the efficiency of package installation on the transport fixture plate while reducing labor costs.

[0007] In an alternative embodiment of the first aspect, a spacer is provided on the base plate; a reference member is located at the first end of the spacer, a feature hole is located at the opposite end of the first end of the spacer, and a feature groove is located at the side end of the spacer.

[0008] In an alternative embodiment of the first aspect, there are multiple placement positions; the multiple placement positions are spaced apart on both sides of the spacer, and the feature groove is adjacent to the placement area.

[0009] In the above-described implementation, this solution designs multiple placement positions, allowing the transport fixture plate designed in this solution to load and transport multiple target packages at once. Furthermore, the multiple placement positions are spaced apart on both sides of the spacer, ensuring a uniform distribution of placement positions. This results in a uniform force distribution on the transport fixture plate after loading the target packages, thereby preventing packages from falling out due to force offset and improving the loading performance of the transport fixture plate.

[0010] In an optional embodiment of the first aspect, a plurality of positioning holes are provided on the base plate; the plurality of positioning holes are distributed at intervals around the placement area, and a plurality of positioning elements are provided on the bottom of the cover plate, with each positioning element corresponding to one of the plurality of positioning holes.

[0011] In an optional embodiment of the first aspect, the plurality of positioning holes include a plurality of first oblong holes and a plurality of second oblong holes; the plurality of first oblong holes and the plurality of second oblong holes are arranged in pairs at intervals, wherein the central axes of the first oblong holes and the second oblong holes are perpendicular to each other.

[0012] In the above-described embodiment, this solution designs the positioning holes to be waist-shaped, with the first and second waist-shaped holes arranged alternately with their central axes perpendicular to each other. This can compensate for the impact of thermal expansion of the transport tooling plate on the cover plate, thereby improving the firmness and reliability of the connection between the cover plate and the base plate.

[0013] In an alternative embodiment of the first aspect, each of the plurality of positioning elements is filled with heavy material.

[0014] In an alternative embodiment of the first aspect, the placement position includes a boss and grooves distributed on both sides of the boss, the grooves being stepped; wherein, the boss is used to place the casing of the target package, and the grooves are used to place the metal pins of the target package.

[0015] In the above-described embodiment, this solution forms a unique package placement position through the boss and the grooves distributed on both sides of the boss. Furthermore, by designing the stepped distribution of the grooves, the designed placement position can be applied to various types and sizes of packages, thereby improving the applicability of the designed transport tooling plate.

[0016] In an optional embodiment of the first aspect, at least one wire bonding port is provided on the cover plate, and a limiting component is provided at each wire bonding port. The limiting component includes a first limiting member and a second limiting member, which are disposed opposite to each other on both sides of the wire bonding port. Each wire bonding port corresponds to a placement position, and each limiting component is used to limit and fix the target package at the corresponding placement position.

[0017] In the above-described implementation, this solution designs a wire bonding port corresponding to each placement position on the base plate and sets a limiting component at the wire bonding port, thereby realizing the wire bonding operation and limiting fixation of the target package on the placement position of the base plate, and thus improving the fixation firmness and operability of the transport tooling plate for the target package.

[0018] In an alternative embodiment of the first aspect, each limiting member includes a recess and a roller; the recess has a mounting groove, and the roller is rotatably disposed in the mounting groove; the roller includes a cylinder and an arc-shaped retaining plate connected to the cylinder, the arc-shaped retaining plate being used to apply a force toward the base plate to the target package when rotated to contact the target package in the placement position.

[0019] In the above-described implementation, the limiting component designed in this solution does not use magnetic materials, but instead adopts a unique rolling limiting structure to achieve the limiting and fixing of each target package, thereby avoiding the problem of fixing failure of the transport tooling plate in a strong magnetic environment, and thus improving the fixing reliability and firmness of the designed transport tooling plate.

[0020] In an alternative embodiment of the first aspect, the reference element includes any one of a reference sphere, a reference cylinder, and a reference block. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0036] In the field of packaging production technology (such as chip packaging, electronic component packaging, etc.), the significance of packaging is to place, fix, seal, protect the chip and enhance its electrothermal performance, that is, to provide strong heat dissipation and electromagnetic shielding, thereby protecting the chip from the influence of the surrounding environment. In order to shorten the interval between packaging processes and improve production efficiency, major companies often design special tooling boards for transporting packaged components (such as chip packaging or electronic component packaging) between them.

[0037] Although existing tooling boards have multiple areas for placing packaged components (such as chip packages or electronic component packages), the placement of packaged components on current transport tooling boards is all done manually, which results in low efficiency.

[0038] To address the aforementioned issues, this application designs a transport fixture plate. This solution uses a placement area on the base plate of the transport fixture plate to place the target package. Furthermore, reference components, feature holes, and feature slots with their centers of mass distributed at different spatial positions are set around the placement area to achieve three-axis positioning, improving manufacturing accuracy. Based on three-axis positioning and a dedicated placement device, the placement of the target package can be automated, significantly improving the level of automation and reducing labor costs while increasing the efficiency of package installation on the transport fixture plate. In addition, this solution uses a cover plate and its limiting components that do not employ magnetic materials, but instead utilize gravity and rolling limiting structures to limit and fix the package, thereby solving the problem of the influence of the magnetic field environment on existing fixture plates and improving the reliability of the transport fixture plate.

[0039] Based on the above ideas, this application first provides a transport tooling plate, such as... Figure 1 As shown, the transport tooling plate includes a base plate 1 and a cover plate 2. The base plate 1 has a placement area 10, which includes at least one placement position 110. Each placement position 110 can be used to place a target package (not shown in the figure). The cover plate 2 can be placed on the base plate 1 to limit and fix the target package on the placement area 10. In this design, the base plate 1 also has a reference element 20, a feature hole 30, and a feature groove 40 distributed on it. The centroids of the reference element 20, the feature hole 30, and the feature groove 40 are distributed at different spatial positions, and the reference element 20, the feature hole 30, and the feature groove 40 are located outside the placement area 10. Specifically, the reference element 20 in this design can be any one of a reference sphere, a reference cylinder, or a reference block.

[0040] The transport fixture plate designed above utilizes a placement area 10 on the base plate 1 to place the target package, and a cover plate 2 to limit and fix the target package. Furthermore, this solution achieves three-coordinate positioning of the transport fixture plate by setting reference elements 20, feature holes 30, and feature grooves 40 with their centers of mass distributed at different spatial positions on the base plate. Based on this three-coordinate positioning and the placement equipment, the placement of the target package can be automated. The three-coordinate positioning method can be any existing three-coordinate positioning method.

[0041] As one possible embodiment, specifically assuming that the reference component 20 in this design is a reference sphere, the three-axis positioning of the transport tooling plate in this design can be achieved in the following way:

[0042] Positioning Principle: The reference sphere is a high-precision sphere with a definite spatial center (center of mass). Multiple points on the surface of the reference sphere are measured using a contact or non-contact probe, and then a mathematical algorithm is used to fit the center position of the reference sphere, which serves as a precise spatial positioning point. The feature groove 40 typically has a specific shape and size, and its position and orientation on the tooling plate are known. During measurement, the probe can detect the edge or bottom surface of the feature groove to obtain its position information in three-coordinate space. Based on the geometric parameters of the feature groove and the measured position data, the accurate position of the feature groove in the coordinate system can be determined, thus providing an orientation and position reference for the positioning of the tooling plate. The feature hole 30 is similar to the feature groove; its center position and diameter are definite. By measuring multiple points on the inner wall of the feature hole, the coordinates of the feature hole's center are calculated, thereby determining the position of the feature hole in three-coordinate space. Multiple feature holes can also be used to determine the flatness and angle information of the tooling plate. Combined with the positioning information of the reference sphere and feature groove, more accurate three-coordinate positioning is achieved.

[0043] Measurement and Calibration: The base plate 1, equipped with the reference component 20, feature hole 30, and feature groove 40, is placed in a coordinate measuring system (CMS). The CMS is used to measure the reference sphere, feature groove, and feature hole. First, multiple points on the surface of the reference sphere are measured, and the coordinates of the reference sphere's centroid are calculated using the measurement software. This centroid is then set as the origin (0,0,0) of the coordinate system. Next, multiple points on the edge or bottom surface of the feature groove are measured to obtain its spatial coordinate data. Based on this data, the position and orientation of the feature groove in the coordinate system with the reference sphere's centroid as the origin are determined, and its alignment with the set X-axis or other coordinate axes is verified. Finally, points on the inner wall of the feature hole are measured, and the coordinates of the feature hole's center are calculated. The position of the feature hole in the coordinate system is checked to ensure it matches expectations, further calibrating the accuracy of the coordinate system. If deviations are found between the measurement results and theoretical values, they can be corrected by adjusting the position of the tooling plate or by re-measuring to ensure the accurate establishment of the coordinate system.

[0044] The X-axis of the established coordinate system can be chosen as the positive direction, passing through the centroid of the reference sphere and parallel to the length of the feature groove or a certain arrangement direction of the feature holes. If there are multiple directions for the feature grooves or feature holes, the direction that best reflects the main positioning direction of the tooling plate or is related to subsequent measurement and operation is selected as the X-axis direction. The Y-axis of the established coordinate system is the direction perpendicular to the X-axis in the plane of the tooling plate. Usually, a vertical direction that is convenient for measurement and calculation is selected as the positive Y-axis direction based on the layout of the feature grooves or feature holes. For example, if the feature grooves are rectangular, the direction parallel to the other side of the rectangle can be selected as the Y-axis direction. The Z-axis of the established coordinate system: According to the right-hand rule, the Z-axis direction is perpendicular to the plane of the tooling plate and forms a right-hand coordinate system with the X-axis and Y-axis. Generally, if the tooling plate is placed horizontally, the positive Z-axis direction can be upward; if the tooling plate has a specific installation angle or usage direction, the positive Z-axis direction is determined according to the actual situation to meet the needs of the entire measurement and operation.

[0045] After establishing a coordinate system with the reference sphere as the origin in the above manner, the positions of each placement position 110 on the base plate 1 can be known, and then the target package can be automatically installed and positioned in conjunction with the placement equipment.

[0046] The above-designed transport fixture plate uses a placement area on its base plate to place the target package. Furthermore, reference parts, feature holes, and feature slots with their centroids distributed at different spatial positions are set around the placement area to achieve three-coordinate positioning, improving production accuracy. Based on three-coordinate positioning and dedicated placement equipment, the placement of the target package can be automated, significantly increasing the level of automation and reducing labor costs while improving the efficiency of package installation on the transport fixture plate.

[0047] In an optional implementation of this embodiment, such as Figure 2 As shown, the base plate 1 of this scheme is provided with a spacer 50, the reference member 20 is located at the first end of the spacer 50, the feature hole 30 is located at the opposite end of the first end of the spacer 50, and the feature groove 40 is located at the side end of the spacer 50. In this way, the spacer 50 separates the reference member 20, the feature hole 30 and the feature groove 40, thereby making the centroids of the reference member 20, the feature hole 30 and the feature groove 40 distributed in different spatial positions.

[0048] As one possible implementation, the spacer 50 designed in this scheme can be in the form of a reinforcing rib. This allows the spacer 50 to not only divide the reference member 20, the feature hole 30 and the feature groove 40, but also to reinforce the base plate, thereby improving the strength and reliability of the base plate 1.

[0049] In an optional implementation of this embodiment, such as Figure 2 and Figure 3 As shown, the base plate 1 of this design has multiple positioning holes 11, which are distributed around the placement area 10 at intervals. The bottom of the cover plate 2 has multiple positioning elements 21, which correspond one-to-one with the multiple positioning holes 11.

[0050] In the above embodiment, the cover plate 2 can be inserted into the positioning hole 11 on the corresponding base plate 1 through the positioning member 21 provided at its bottom, thereby realizing the detachable connection between the cover plate 2 and the base plate 1.

[0051] Specifically, as one possible implementation, the positioning component 21 designed in this scheme can be a positioning cylinder. The bottom of the cover plate 2 can be provided with multiple threaded holes (not shown in the figure). One end of the positioning cylinder is a threaded end, which is positioned within the threaded hole of the cover plate 2. The other end of the positioning cylinder can be inserted into the corresponding positioning hole 11 of the base plate 1, thereby achieving a detachable connection between the cover plate 2 and the base plate 1. As a specific example, the threaded holes and positioning cylinder designed in this scheme can be eight as shown in the figure. The eight threaded holes and positioning cylinder are evenly distributed on the bottom of the cover plate 2, thereby making the connection between the cover plate 2 and the base plate 1 more secure.

[0052] In an optional embodiment of this design, a filling cavity can be opened inside the other end of the positioning cylinder. The filling cavity can be filled with heavy or high-density materials. By increasing the weight of each positioning cylinder, the weight of the cover plate is increased, thereby making the cover plate 2 and the base plate 1 fit more tightly under the action of gravity.

[0053] In an optional implementation of this embodiment, as one possible implementation, such as Figure 2 As shown, the multiple positioning holes 11 designed in this scheme can all be in the form of oblong holes. Specifically, the multiple positioning holes 11 can include multiple first oblong holes 111 and multiple second oblong holes 112. The multiple first oblong holes 111 and multiple second oblong holes 112 are arranged in pairs at intervals, wherein the central axes of the first oblong holes 111 and the second oblong holes 112 are perpendicular to each other.

[0054] In the above-described embodiment, this solution designs the positioning holes to be waist-shaped holes, and the first and second waist-shaped holes, which are perpendicular to each other on the central axis, are arranged in pairs. This can compensate for the impact of thermal expansion of the transport tooling plate on the cover plate 2, thereby improving the firmness and reliability of the connection between the cover plate 2 and the base plate 1.

[0055] In an optional implementation of this embodiment, such as Figure 2 As shown, this design allows for multiple placement positions 110, spaced apart on both sides of the spacer 50, with the feature groove 40 adjacent to the placement area 10. For details, please refer to... Figure 2 Multiple placement positions 110 are spaced apart on both sides of the spacer 50 to form a first placement area 1110 and a second placement area 1120. The feature groove 40 can be adjacent to one of the placement areas; for example, the feature groove 40 can be adjacent to the first placement area 1110. In the case where the above spacing forms two placement areas, such as... Figure 1 As shown, the cover plate 2 designed in this scheme can also be two. The first cover plate can be placed on the first placement area 1110, and the second cover plate can be placed on the second placement area 1120, so that the designed cover plate can cover all placement positions, and the reference member 20, the feature hole 30 and the feature groove 40 are located on the outer periphery of the cover plate 2 and are not blocked by the cover plate.

[0056] In the above-described embodiment, this solution designs multiple placement positions, which allows the transport fixture plate designed in this solution to load and transport multiple target packages at one time. Furthermore, the multiple placement positions designed in this solution are distributed at intervals on both sides of the spacer 50, which makes the placement positions evenly distributed. This ensures that the transport fixture plate formed after loading the target packages is evenly stressed, thereby avoiding the situation where the packages fall out due to force offset and improving the loading performance of the transport fixture plate.

[0057] In an optional implementation of this embodiment, such as Figure 4 As shown, each placement position 110 of this invention may include a boss 1111 and grooves 1112 distributed on both sides of the boss. The grooves 1112 are stepped. Since the package generally contains a shell and its metal leads, and the metal leads are bent, the boss 1111 in the placement position 110 of this invention can place the shell of the target package, and the grooves 1112 can just place the metal leads of the target package. Furthermore, since the grooves 1112 in this invention are stepped, the grooves 1112 can support metal leads of different sizes through different height steps, thereby making the placement position of this invention adaptable to packages of various sizes and types.

[0058] In the above-described embodiment, this solution forms a unique package placement position through the boss and the grooves distributed on both sides of the boss. Furthermore, by designing the stepped distribution of the grooves, the designed placement position can be applied to various types and sizes of packages, thereby improving the applicability of the designed transport tooling plate.

[0059] In an optional embodiment of this example, in order to adapt to the base plate 1 described above, such as Figure 3As shown, the cover plate 2 designed in this scheme can be provided with multiple wire bonding ports 24. Each wire bonding port 24 is provided with a limiting component 25. The limiting component 25 includes a first limiting member 251 and a second limiting member 252. The first limiting member 251 and the second limiting member 252 are arranged opposite to each other on both sides of the wire bonding port 24. Each wire bonding port 24 corresponds to a placement position 110.

[0060] In the above embodiment, when the cover plate 2 is placed on the base plate 1, each wire bonding port 24 corresponds to a placement position 110. The package on the placement position 110 can be contacted or operated through the wire bonding port 24. The limiting component 25 provided at each wire bonding port 24 can limit and fix the target package on the corresponding placement position 110. Specifically, the first limiting component 251 and the second limiting component 252 can apply a force toward the base plate 1 to the target package, thereby pressing and fixing the target package at the corresponding placement position 110 of the base plate 1.

[0061] In the above-described implementation, this solution designs a wire bonding port corresponding to each placement position on the base plate and sets a limiting component at the wire bonding port, thereby realizing the wire bonding operation and limiting fixation of the target package on the placement position of the base plate, and thus improving the fixation firmness and operability of the transport tooling plate for the target package.

[0062] In an optional implementation of this embodiment, such as Figure 5 As shown, the first limiting member 251 or the second limiting member 252 designed in this scheme may include the following structure: a recessed platform 2510 and a roller 2520. The recessed platform 2510 is provided with a mounting groove 25110, and the roller 2520 is rotatably disposed in the mounting groove 25110. The roller 2520 includes a cylinder 25210 and an arc-shaped locking platform 25220 connected to the cylinder 25210.

[0063] The limiting component designed above allows the roller 2520 to rotate within the mounting groove 25110. When the arc-shaped retaining plate 25220 on the roller 2520 rotates to contact the target package on the placement position 110, the arc-shaped retaining plate 25220 on the roller 2520 is subjected to force and rotates within the recess 2510. At this time, the distance between the first limiting component 251 and the second limiting component 252 on both sides of the wire bonding port 24 is shortened, thereby achieving the limiting of the package.

[0064] In the above-described implementation, the limiting component designed in this solution does not use magnetic materials, but instead adopts a unique rolling limiting structure to achieve the limiting and fixing of each target package, thereby avoiding the problem of fixing failure of the transport tooling plate in a strong magnetic environment, and thus improving the fixing reliability and firmness of the designed transport tooling plate.

[0065] In an optional embodiment of this design, machine pickup holes 26 can be provided at both ends of the cover plate 2 to facilitate the pickup machine's pickup of the cover plate 2. Additionally, as... Figure 2 As shown, the bottom plate 1 designed in this scheme has groove-shaped structures 13 at both ends to facilitate the loading and unloading of the cover plate, and a directional groove 14 for identifying the packaging direction is provided at the end of the bottom plate 1 with feature hole 30. In this way, the design of the groove-shaped structure 13 makes the loading and unloading of the cover plate 2 more convenient, and the direction of the package in the transport tooling plate can be identified by the directional groove 14.

[0066] The above-designed transport tooling plate allows for the automatic installation of the target package component using the following method:

[0067] Before installing the target package onto the transport fixture plate, the transport fixture plate can be placed in the working area of ​​the coordinate measuring system (CMS). In this case, the CMS can collect the position information of multiple feature points on the transport fixture plate within the working area. This feature point position information includes the position information of the reference component, feature holes, and feature slots on the transport fixture plate. Then, based on the multiple feature point position information, a coordinate system is established with the centroid of the reference component as the origin. The coordinate system can be established using the coordinate measuring machine (CMM) method, and the specific process is as described above:

[0068] The positioning principle described in the above embodiments is as follows: The reference sphere is a high-precision sphere with a definite spatial position at its center (centroid). Multiple points on the surface of the reference sphere are measured using a contact or non-contact probe, and then the center position of the reference sphere is fitted using a mathematical algorithm, which serves as a precise spatial positioning point. The feature groove 40 typically has a specific shape and size, and its position and orientation on the tooling plate are known. During measurement, the probe can detect the edge or bottom surface of the feature groove to obtain its position information in the three-coordinate space. Based on the geometric parameters of the feature groove and the measured position data, the accurate position of the feature groove in the coordinate system can be determined, thus providing an orientation and position reference for the positioning of the tooling plate. The feature hole 30 is similar to the feature groove, with its center position and diameter parameters being determined. By measuring multiple points on the inner wall of the feature hole, the coordinates of the center of the feature hole are calculated, thereby determining the position of the feature hole in the three-coordinate space. Multiple feature holes can also be used to determine the flatness and angle information of the tooling plate. Combined with the positioning information of the reference sphere and the feature groove, more accurate three-coordinate positioning is achieved.

[0069] One possible implementation method for measurement and calibration in the above embodiments is described as follows: A base plate 1, equipped with a reference component 20, a feature hole 30, and a feature groove 40, is placed in a coordinate measuring system (CMS). The CMS is then used to measure the reference sphere, feature groove, and feature hole. First, multiple points on the surface of the reference sphere are measured, and the centroid coordinates of the reference sphere are calculated using measurement software. This centroid is then set as the origin (0,0,0) of the coordinate system. Next, multiple points on the edge or bottom surface of the feature groove are measured to obtain its spatial coordinate data. Based on this data, the position and orientation of the feature groove in the coordinate system with the centroid of the reference sphere as the origin are determined, and its alignment with the set X-axis or other coordinate axes is verified. Finally, points on the inner wall of the feature hole are measured, and the center coordinates of the feature hole are calculated. The position of the feature hole in the coordinate system is checked to ensure it matches expectations, further calibrating the accuracy of the coordinate system. If a deviation is found between the measurement results and the theoretical values, it can be corrected by adjusting the position of the tooling plate or by re-measuring to ensure the accurate establishment of the coordinate system.

[0070] The X-axis of the established coordinate system can be chosen as the positive direction, passing through the centroid of the reference sphere and parallel to the length of the feature groove or a certain arrangement direction of the feature holes. If there are multiple directions for the feature grooves or feature holes, the direction that best reflects the main positioning direction of the tooling plate or is related to subsequent measurement and operation is selected as the X-axis direction. The Y-axis of the established coordinate system is the direction perpendicular to the X-axis in the plane of the tooling plate. Usually, a vertical direction that is convenient for measurement and calculation is selected as the positive Y-axis direction based on the layout of the feature grooves or feature holes. For example, if the feature grooves are rectangular, the direction parallel to the other side of the rectangle can be selected as the Y-axis direction. The Z-axis of the established coordinate system: According to the right-hand rule, the Z-axis direction is perpendicular to the plane of the tooling plate and forms a right-hand coordinate system with the X-axis and Y-axis. Generally, if the tooling plate is placed horizontally, the positive Z-axis direction can be upward; if the tooling plate has a specific installation angle or usage direction, the positive Z-axis direction is determined according to the actual situation to meet the needs of the entire measurement and operation.

[0071] By establishing a three-dimensional coordinate system in the target space using the above method, this solution can obtain the theoretical geometric model of the pre-configured transport tooling plate. This theoretical geometric model represents the shape of the designed transport tooling plate, the positional relationships of various components, etc. Therefore, based on the theoretical geometric model of the transport tooling plate and the three-dimensional coordinate system in the target space, this solution can obtain the actual geometric model of the transport tooling plate. That is, this solution can obtain the spatial coordinate information of each placement position of the transport tooling plate. On this basis, the controller can control the placement mechanism to place the target package in the corresponding placement position according to the spatial coordinate information of each placement position, thereby realizing the installation of the package of the transport tooling plate.

[0072] The above-designed method for installing the packaged components on the transport tooling plate involves setting a placement area on the base plate of the transport tooling plate to place the target packaged component. Furthermore, three-coordinate positioning is achieved by setting reference components, feature holes, and feature grooves with their centroids distributed at different spatial locations around the placement area. Based on the three-dimensional coordinate system established by the three-coordinate positioning and the theoretical geometric model of the transport tooling plate, the aperture coordinates of each placement position in the transport tooling plate can be determined. Then, based on the spatial coordinates of each placement position, the packaged component placement mechanism is controlled to place and install the target packaged component, thus automating the placement of the target packaged component and significantly improving the degree of automation. This increases the efficiency of packaged component installation on the transport tooling plate while reducing labor costs.

[0073] In an optional embodiment of this invention, when the automated installation of the target package is completed, the placement mechanism of this solution can place the cover plate on the base plate. At this time, the positioning cylinder on the cover plate aligns with the positioning hole on the base plate, and the limiting component on the cover plate starts to work. When the roller contacts the package, the arc-shaped platform on the roller is subjected to force and rotates within the recess. At this time, the distance between the first and second limiting components on both sides of the solder joint shortens, thereby limiting the package. Furthermore, the cover plate can be removed through the groove structure at both ends of the base plate.
