Detailed Implementation

[0010] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0011] Before installation or use, pins are placed on a corresponding carrier for easy gripping by a robotic arm. However, pins on the carrier may be tilted to the left or right, causing the robotic arm to bend the pins or cause copper leakage at the pin tips when gripping them, resulting in wasted equipment downtime and the production of defective products.

[0012] Please see Figure 1 and Figure 2 This application provides a floating plate carrier, including a carrier 10 and a floating member 20. The carrier 10 includes a first support portion 11 and a second support portion 12, with the second support portion 12 connected to one side of the first support portion 11 along the height direction Z. The floating member 20 includes a plate body portion 21 and an elastic portion 22. The plate body portion 21 is spaced apart from the carrier 10 and located on the side of the second support portion 12 opposite to the first support portion 11. The plate body portion 21 has a plurality of through holes 211 for a needle structure 30 to pass through. The elastic portion 22 is located on the side of the plate body portion 21 facing the first support portion 11 and is connected to both the plate body portion 21 and the first support portion 11. The plate body portion 21 is configured to support the needle structure 30, such that the needle structure 30 is spaced apart from the second support portion 12.

[0013] It is understood that the needle structure 30 is supported by the floating component 20 on the floating plate carrier. The needle structure 30 can be a pin. The plate body 21 of the floating component 20 has multiple through holes 211, and the needle structure 30 can pass through the corresponding through hole 211. The needle structure 30 has a shoulder structure that protrudes along the length direction X. The needle structure 30 includes a main body 31 and an overlapping part 32. The main body 31 is the main structure of the needle structure 30, and the overlapping part 32 is the shoulder structure of the needle structure 30. When the main body 31 passes through the corresponding through hole 211, the overlapping part 32 cannot pass through the through hole 211 and will overlap on the upper surface of the plate body 21. An elastic part 22 is provided between the plate body 21 and the first support part 11. The elastic part 22 supports the plate body 21, creating a certain gap between the needle structure 30 supported on the plate body 21 and the second support part 12. The elastic part 22 can be a spring.

[0014] When the plate body 21 is in its initial state, that is, when the plate body 21 is not subjected to downward pressure, the needle structure 30 is inserted into the corresponding through hole 211 by the robotic arm. When about half of the needle structure 30 has passed through the through hole 211, the robotic arm is released, allowing the needle structure 30 to fall freely until the overlapping portion 32 on the needle structure 30 contacts the plate body 21. The plate body 21 supports the needle structure 30, ensuring that the needle structure 30 does not contact the second support portion 12 on the first support portion 11, maintaining a certain distance. The plate body 21 supports the overlapping portion 32 on the needle structure 30, allowing the needle structure 30 to hang naturally, thereby maintaining a vertical state and preventing tilting. When the robot grips the needle structure 30 on the plate body 21, the robot will press the plate body 21 downward, causing both the plate body 21 and the needle structure 30 supported on it to move downward. The bottom end of the needle structure 30 will come into contact with the second support part 12, which will support the needle structure 30. Under the pressure of the robot, the plate body 21 continues to move downward, creating a certain gap between the overlapping part 32 on the needle structure 30 and the upper surface of the plate body 21. This allows the robot to lock the overlapping part 32, remove the needle structure 30 from the through hole 211, and move it into the pin hole of the mold insert, thus completing the transfer of the needle structure 30.

[0015] This structure ensures that the needle structure 30 remains vertical, preventing tilting and avoiding damage to the needle structure 30 during the gripping process by the robotic arm, such as bending the needle structure 30 or rubbing against it, which could cause the copper tip to be exposed. This improves the product yield and consistency, reduces equipment downtime, and increases production efficiency.

[0016] Please see Figure 3 and Figure 4In conjunction with the above embodiments, in some embodiments, the first support portion 11 has a limiting hole 111 that extends through the plate body portion 21 along the height direction Z. The limiting hole 111 has a stepped surface 112 that is disposed opposite to the plate body portion 21. The floating plate carrier also includes a limiting member 40, which is connected to the plate body portion 21. A portion of the limiting member 40 is located in the limiting hole 111 and can slide within the limiting hole 111 along the height direction Z. Along the height direction Z, the orthogonal projection portion of the limiting member 40 is located on the stepped surface 112.

[0017] It is understood that limiting holes 111 can be provided through the first support part 11, and the number and position of the limiting holes 111 can be set as needed. A stepped surface 112 is provided inside each limiting hole 111, and the stepped surface 112 is positioned away from the plate part 21, making the limiting hole 111 have an inverted T-shaped structure. Simultaneously, a limiting member 40 is slidably provided inside each limiting hole 111, and the top end of the limiting member 40 extends to the outside of the limiting hole 111 and connects with the plate part 21. When the plate part 21 slides along the height direction Z, it also drives the limiting member 40 to move in the same direction.

[0018] The stepped surface 112 can block the limiting member 40 to a certain extent. When the limiting member 40 moves upward and abuts against the stepped surface 112, the stepped surface 112 will limit the upward movement distance of the limiting member 40, thereby limiting the distance between the plate part 21 and the first support part 11, which also limits the height that the elastic part 22 lifts the plate part 21, so that the plate part 21 is kept at a suitable height.

[0019] Please see Figure 3 and Figure 4 In conjunction with the above embodiments, in some embodiments, the limiting member 40 includes a connecting portion 41 and a limiting portion 42. One end of the connecting portion 41 is detachably connected to the plate portion 21, and the other end is embedded in the limiting hole 111. The limiting portion 42 is slidably disposed in the limiting hole 111 and connected to the connecting portion 41. Along the height direction Z, the orthographic projection of the limiting portion 42 is located on the step surface 112.

[0020] Understandably, the top end of the connecting part 41 can be detachably connected to the plate part 21 via screws, clips, or other structures, facilitating assembly and disassembly. The bottom end of the connecting part 41 is embedded into the corresponding limiting hole 111. A limiting part 42 is provided inside the limiting hole 111, and the bottom end of the connecting part 41 is connected to the limiting part 42, forming an inverted T-shaped structure. The limiting part 42 can slide up and down along the height direction Z inside the limiting hole 111, thus facilitating the sliding of the connecting part 41 and the plate part 21 along the height direction Z. At the same time, the stepped surface 112 can provide a certain degree of obstruction to the limiting part 42, limiting the upward sliding distance of the limiting part 42, thereby limiting the height of the plate part 21 and preventing the plate part 21 from being too tall and affecting its use.

[0021] Please see Figure 5 In conjunction with the above embodiments, in some embodiments, the floating plate carrier further includes a guide member 50, which passes through the first support portion 11 and is connected to the first support portion 11. The guide member 50 is connected to the plate body portion 21 and is used to move the plate body portion 21 along the height direction Z.

[0022] It is understandable that by connecting the guide members 50 to the first support portion 11 and the plate portion 21 respectively, the movement of the plate portion 21 can be guided, allowing the plate portion 21 to move stably along the height direction Z without tilting during the movement, thus reducing the risk of the needle structure 30 tilting. The guide members 50 can be symmetrically arranged left and right; preferably, guide members 50 are connected at all four corners of the plate portion 21.

[0023] Please see Figure 5 In conjunction with the above embodiments, in some embodiments, the guide member 50 includes a guide sleeve portion 51 and a guide post portion 52. The guide sleeve portion 51 penetrates through and is connected to the first support portion 11, and has a guide hole 511 extending along the height direction Z. The guide post portion 52 is connected to the plate body portion 21 and is at least partially disposed within the guide hole 511, and the guide post portion 52 is movable along the height direction Z within the guide hole 511.

[0024] It is understood that the guide member 50 can be composed of a guide sleeve portion 51 and a guide post portion 52. The guide sleeve portion 51 is disposed through the first support portion 11 and remains in a fixed position. The guide post portion 52 is at least partially disposed in the guide hole 511 inside the guide sleeve portion 51, so that the guide post portion 52 can slide along the height direction Z under the guidance of the guide hole 511, ensuring the stability of the guide post portion 52 sliding up and down and avoiding shaking or tilting during the sliding process, thereby improving the stability of the plate portion 21 during the up and down movement. The bottom end of the guide post portion 52 can be disposed inside the guide hole 511 or can pass through the guide hole 511. The larger the dimension of the portion of the guide post portion 52 located inside the guide hole 511 along the height direction Z, the higher the stability of the guide post portion 52 when sliding inside the guide hole 511.

[0025] Please see Figure 5 , Figure 6 and Figure 7 In conjunction with the above embodiments, in some embodiments, the plate portion 21 has a connecting hole 212 extending along the height direction Z and a first slot 213 extending along the length direction X. The first slot 213 communicates with the connecting hole 212, and the guide post portion 52 passes through the connecting hole 212. The height direction Z intersects the length direction X. The guide post portion 52 has a second slot 521, and the floating member 20 further includes a snap-fit ​​portion 23, which passes through the first slot 213 and is embedded in the second slot 521.

[0026] Understandably, connecting holes 212 are provided on the plate body 21 at positions corresponding to the guide post 52. The number of connecting holes 212 is the same as the number of guide post 52, allowing the top of each guide post 52 to be inserted into the interior of a connecting hole 212. A first slot 213 can be formed on the side of the plate body 21, allowing the first slot 213 to communicate with the corresponding connecting hole 212. A second slot 521 communicating with the first slot 213 is also formed at the top of the guide post 52. The snap-fit ​​part 23 passes through the interior of the first slot 213 and is inserted into the corresponding second slot 521, forming a snap-fit ​​structure with the guide post 52. This connects the guide post 52 and the plate body 21, preventing relative sliding between them. This structure facilitates the assembly and disassembly of the guide post 52 and the plate body 21, improving the ease of assembly and disassembly.

[0027] When installing the guide post 52, it can be passed through the connecting hole 212 from top to bottom and then embedded into the corresponding guide sleeve 51. A positioning boss can be provided in the connecting hole 212 so that the positioning boss abuts against the top of the guide post 52, thereby making the first slot 213 and the second slot 521 correspond and connect precisely, facilitating the quick insertion of the snap-fit ​​part 23 into the second slot 521 and reducing the difficulty of connection. The snap-fit ​​part 23 can be connected to the plate part 21 by bolts to improve the stability of the snap-fit ​​part 23 and prevent it from easily sliding out of the first slot 213.

[0028] Please see Figure 8 In conjunction with the above embodiments, in some embodiments, the floating plate carrier further includes a base 60, which is disposed on the side of the first support portion 11 away from the plate body portion 21. The base 60 has a receiving hole 61, the bottom end of the guide sleeve portion 51 is embedded in the receiving hole 61, the guide post portion 52 passes through the guide hole 511, and the guide member 50 further includes a blocking portion 53, which is disposed in the receiving hole 61 and connected to the guide post portion 52. The orthogonal projection of the blocking portion 53 along the height direction Z is at least partially located on the guide sleeve portion 51.

[0029] Understandably, when the guide sleeve 51 penetrates the first support 11, a base 60 can be provided at the bottom of the first support 11. A receiving hole 61 can be provided on the base 60 at a position corresponding to the guide sleeve 51, allowing the bottom end of the guide sleeve 51 to be embedded in the receiving hole 61. Simultaneously, the guide hole 511 in the guide sleeve 51 can communicate with the receiving hole 61. A blocking part 53 can be provided inside the receiving hole 61. The guide post 52 passes through the guide hole 511 and connects to the blocking part 53. The two can be connected by screws for easy disassembly and installation. The orthogonal projection of the blocking part 53 in the height direction Z will at least partially fall on the guide sleeve 51. That is, when the guide post 52 moves the blocking part 53 upward, the guide sleeve 51 will block the blocking part 53, thereby limiting the upward movement distance of the blocking part 53. This limits the maximum height of the plate body 21, preventing the plate body 21 from becoming too tall under the support of the elastic part 22, which would be detrimental to its use.

[0030] Please see Figure 9 , Figure 10 , Figure 11 and Figure 12 In conjunction with the above embodiments, in some embodiments, the plate portion 21 has two first guide surfaces 214 disposed opposite to each other in the longitudinal direction X. The first guide surfaces 214 are respectively connected to the inner wall surface of the through hole 211 and the top surface of the plate portion 21, such as... Figure 11As shown, there is a first gap L1 between the two first guide surfaces 214, and the first gap L1 gradually decreases along the direction from the plate portion 21 to the second support portion 12. The plate portion 21 has two second guide surfaces 215 arranged opposite to each other in the width direction Y. The two second guide surfaces 215 are disposed between the two first guide surfaces 214, and the second guide surfaces 215 are respectively connected to the inner wall surface of the through hole 211 and the top surface of the plate portion 21, as shown. Figure 12 As shown, a second spacing L2 exists between the two second guide surfaces 215, and the second spacing L2 gradually decreases along the direction from the plate portion 21 to the second support portion 12. The width direction Y, height direction Z, and length direction X intersect each other; preferably, the width direction Y, height direction Z, and length direction X are perpendicular to each other. The length direction X is the direction in which the length of the support member 10 is located, the width direction Y is the direction in which the width of the support member 10 is located, and the height direction Z is the direction in which the height of the support member 10 is located.

[0031] It is understood that the top surface of the plate body 21 and the inner wall surface of the through hole 211 are connected by two first guide surfaces 214 and two second guide surfaces 215. Each guide surface is an inclined surface, and the two first guide surfaces 214 and two second guide surfaces 215 together form a guide opening, the size of which gradually decreases from top to bottom. When the robot arm drives the needle structure 30 to pass through the through hole 211, the two first guide surfaces 214 and two second guide surfaces 215 can play a certain guiding role for the needle structure 30, so that the needle structure 30 can be quickly inserted and passed through the through hole 211. The through hole 211 can also limit the needle structure 30. When the needle structure 30 passes through the through hole 211, multiple inner wall surfaces of the through hole 211 fit against multiple sides of the needle structure 30, so that the needle structure 30 can remain vertical. This is beneficial for the subsequent gripping by the robot arm and avoids damage to the needle structure 30 during gripping due to tilting. This reduces product scrap, improves yield and consistency, and also reduces the number of equipment downtimes, thus improving production efficiency.

[0032] Please see Figure 9 , Figure 13 and Figure 14 In conjunction with the above embodiments, in some embodiments, the plate portion 21 has a plurality of through-hole groups 24 spaced apart along the width direction Y, and the through-hole groups 24 have a plurality of through-holes 211 spaced apart along the length direction X. The second support portion 12 has a plurality of guide grooves 121 disposed toward the plate portion 21, the guide grooves 121 extending along the length direction X, and each guide groove 121 corresponding to one through-hole group 24. The guide groove 121 has two third guide surfaces 122 disposed opposite to each other in the width direction Y, and a third distance L3 is provided between the two third guide surfaces 122. The third distance L3 gradually decreases along the direction from the plate portion 21 to the second support portion 12.

[0033] It is understandable that, such as Figure 9 As shown, multiple through-hole groups 24 can be provided on the plate body 21, and multiple guide grooves 121 are provided on the second support part 12. The position and number of guide grooves 121 correspond to the position and number of through-hole groups 24, respectively. Each through-hole group 24 includes multiple through holes 211, and each through hole 211 can allow a needle structure 30 to pass through. Among them, the guide groove 121 has two inclined third guide surfaces 122, so that the opening of the guide groove 121 gradually decreases from top to bottom. The guide groove 121 corresponds to the position of the needle structure 30. During the descent of the needle structure 30, if the needle structure 30 tilts, the two third guide surfaces 122 can play a certain guiding role for the needle structure 30, so as to keep the needle structure 30 in a vertical state as much as possible, which facilitates the gripping of the robot and reduces the damage caused to the needle structure 30 by the robot.

[0034] Please see Figure 1 and Figure 2 This application also provides a component retrieval system, including a floating plate carrier, a needle structure 30, and a gripping structure as described above. The floating plate carrier includes a plate body 21 with a through hole 211. The needle structure 30 includes a main body 31 and an overlapping portion 32 connected to each other. The main body 31 passes through the through hole 211, and its bottom end is spaced apart from the support member 10 of the floating plate carrier. The overlapping portion 32 overlaps the side of the plate body 21 opposite to the support member 10. The gripping structure is used to grip the needle structure 30; the gripping structure is not shown in the drawing.

[0035] It is understandable that the needle structure 30 passes through the through hole 211 on the plate body 21, and the overlapping part 32 on the needle structure 30 abuts against the top surface of the plate body 21, so that the plate body 21 can support the needle structure 30. The bottom end of the needle structure 30 has a certain distance from the bearing member 10, so that the needle structure 30 can hang freely, which is conducive to keeping the needle structure 30 in a vertical state, thereby facilitating the gripping structure to grip the needle structure 30. The gripping structure can be a robotic arm.
