Description

Technical Field

[0001] This application relates to the field of semiconductor testing technology, specifically to a stage for carrying boards and a stage device for assisting in changing board slots. Background Technology

[0002] Semiconductor testing is a core component of the semiconductor industry chain, ensuring chip quality, screening defective products, and optimizing design and manufacturing processes, spanning the entire lifecycle from chip R&D to mass production. A common method is burn-in board (BIB) aging testing, which involves placing the device under test (DUT) on the BIB, then placing the BIB into a testing machine to test the DUT under different temperature, voltage, and signal conditions to verify its reliability.

[0003] During BIB aging testing, BIBs need to be manually moved and placed onto a transfer cart. The transfer cart typically has 28 slots, each holding one BIB. When it's necessary to change the slot of a BIB on the transfer cart—for example, if a BIB is in slot 1 and needs to be moved to slot 7—it requires manual pulling out of slot 1 and inserting it into slot 7. However, changing BIB slots requires workers to control their strength, handle them gently, and avoid collisions, placing a significant physical and mental strain on them. Furthermore, due to the large number of BIB slots needed and the heavy manual workload, there is a risk of lower back strain.

[0004] In related technologies, a platform device for changing the slot of a board in conjunction with a transfer trolley has been proposed. It includes a platform for temporarily storing the board. However, the platform structure does not have a board locking function, and there is a risk that the board may shake or even fall off when changing the slot.

[0005] This section provides background information related to this application, which is not necessarily prior art. Utility Model Content

[0006] The purpose of this application is to solve or at least alleviate some or all of the above-mentioned problems. Therefore, the purpose of this application is to provide a platform for supporting sheet metal parts and a platform device for assisting in changing sheet metal parts in slots, which can prevent the sheet metal parts inside the platform from shaking or falling, and can cooperate with a transfer trolley to assist in manually changing sheet metal parts in slots, reducing manual labor and lowering the risk of lumbar muscle strain for workers.

[0021] As an optional solution for the platform device for assisting in changing the slot of the plate, the lifting mechanism drives the platform to rise or fall by a stroke S1 in a single operation, and the layer spacing between two adjacent temporary storage slots is S2, where S1 = n * S2, and n is a positive integer.

[0022] As an optional solution for the platform device for assisting in changing the slot of the plate, a baffle mechanism is also included, the baffle mechanism including at least one baffle assembly for blocking the front side of the plate in at least the temporary storage slot.

[0023] As an optional solution for the platform device for assisting in changing the slot of the plate, the baffle assembly includes a baffle driver and a baffle member. The baffle member extends vertically and its height is not less than the height of the platform. The baffle driver is mounted on the frame, and its output end is connected to the baffle member and is used to drive the baffle member to move in the left and right direction so that the baffle member moves to the front side of the plate in the temporary storage slot.

[0026] As an optional solution for the platform device for assisting in changing plate slots, the lifting mechanism includes a lifting driver, a transmission assembly, and at least one pulley assembly. The pulley assembly includes an upper synchronous pulley, a lower synchronous pulley, and a synchronous belt. The upper and lower synchronous pulleys are both mounted on the frame and located at the upper and lower ends of the frame, respectively. The synchronous belt is wound around the upper and lower synchronous pulleys. The lifting driver is mounted on the frame and drives the upper synchronous pulleys of all the pulley assemblies to rotate through the transmission assembly.

This makes it easier for workers to pull the panel directly from the transfer slot into the temporary storage slot. The whole process basically does not require workers to lift and change the panel, which can reduce the amount of manual work, reduce the risk of lumbar muscle strain for workers, and improve the safety of the slot changing operation.

[0050] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0051] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0052] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0053] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0054] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0055] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0056] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0057] like Figure 1 As shown, the transfer trolley 200 has multiple layers of transfer slots 201 arranged vertically at intervals, and each layer of transfer slots 201 can hold one plate 100. It should be noted that... Figure 1 The dotted lines between each layer of transfer slots 201 are only to show the approximate dividing line of each layer of transfer slots 201. In reality, there is no such dividing line. Each layer of transfer slots 201 is interconnected in the vertical direction to facilitate the user to place and take out the board 100.

[0058] In some embodiments, board 100 may be a BIB (Bipolar Interface Board) used in semiconductor testing. A BIB is a key adapter carrier used in semiconductor aging testing. It is designed to withstand high temperatures and high pressures and can establish a precise electrical connection between the test system and the chip under test to achieve parallel stress loading on multiple chips and to screen for potentially defective chips in advance. In other embodiments, board 100 may also be a DIB (Device Interface Board), a calibration board, etc., and there are no limitations on this.

[0059] In some embodiments, the transfer trolley 200 has 28 layers of transfer slots 201, wherein every 7 layers form an area, and there are a total of four areas. In actual operation, different areas can be distinguished by different colors so that workers can quickly determine which area the board 100 is in, and thus quickly determine which layer of transfer slot 201 the board 100 is in.

[0060] Assuming that panel 100 is in transfer slot 201 on the first floor, and needs to be moved to transfer slot 201 on the seventh floor, without external assistance, it would require a person to squat down and pull panel 100 out of the first floor and then move it to the seventh floor. This would involve a large amount of manual handling work, posing a risk of back injury, and there is also a risk that panel 100 might fall if handled entirely by hand.

[0061] Based on the above issues, such as Figures 2 to 7 As shown, this application provides a platform device and a method for assisting in changing the slot of a panel, which can be used in conjunction with a transfer trolley 200 to assist in manually changing the slot of a panel 100, reducing the amount of manual work, lowering the risk of lumbar muscle strain for workers, and improving the safety of the operation of changing the panel 100.

[0062] For ease of description of the technical solution of this application, Figure 2 The height direction of the platform device is defined as the vertical direction; the open end of the platform device is defined as the front side, and the direction opposite to the front side is defined as the rear side; furthermore, when the worker faces the front side of the platform device, the worker's left hand side is the left side, and the worker's right hand side is the right side.

[0063] like Figure 2 As shown, the auxiliary plate replacement slot platform device provided in this application includes a frame 1, a platform 2, and a lifting mechanism 3. The front side of the frame 1 is open to facilitate the loading or unloading of the plate 100 from the front. The platform 2 is vertically and vertically mounted on the frame 1. The platform 2 has multiple layers of temporary storage slots 20 arranged at intervals in the vertical direction. The lowest temporary storage slot 20 can be aligned with the lowest transfer slot 201, and the distance between two adjacent layers of temporary storage slots 20 is the same as the distance between two adjacent layers of transfer slots 201. Equal; The lifting mechanism 3 is installed on the frame 1. The output end of the lifting mechanism 3 is connected to the platform 2 and is used to drive the platform 2 to rise and fall in the vertical direction so that one of the temporary storage slots 20 is aligned with the transfer slot 201 on which the plate 100 is placed. This makes it easier for the staff to pull the plate 100 directly from the transfer slot 201 into the temporary storage slot 20. The whole process basically does not require the staff to lift the plate 100 for transfer, which can reduce the amount of manual work, reduce the risk of lumbar muscle strain for the staff, and improve the safety of the slot replacement operation.

[0064] The lifting mechanism 3 includes a lifting drive 31, a transmission assembly 32, and at least one pulley assembly 33. The pulley assembly 33 includes an upper synchronous pulley 331, a lower synchronous pulley 332, and a synchronous belt 333. The upper synchronous pulley 331 and the lower synchronous pulley 332 are both mounted on the frame 1 and located at the upper and lower ends of the frame 1, respectively. The synchronous belt 333 is wound around the upper synchronous pulley 331 and the lower synchronous pulley 332. The lifting drive 31 is mounted on the frame 1 and drives the upper synchronous pulley 331 of all pulley assemblies 33 to rotate through the transmission assembly 32.

[0065] In some embodiments, the number of pulley assemblies 33 is four; the transmission assembly 32 includes a first driving pulley 321, a first driven pulley 322, a second driving pulley 323, a second driven pulley 324, a first transmission belt 325, a second transmission belt 326, a first transmission shaft, and a second transmission shaft; both the first and second transmission shafts extend in a left-right direction, and upper synchronous pulleys 331 are connected to both the left and right sides of the first and second transmission shafts; the first driving pulley 321 is connected to the output end of the lifting driver 31, the first driven pulley 322 is connected to the first transmission shaft, and the first transmission belt 325 is wound around the first driving pulley 321 and the first driven pulley 322; the second driving pulley 323 is connected to the first transmission shaft, the second driven pulley 324 is connected to the second transmission shaft, and the second transmission belt 326 is wound around the second driving pulley 323 and the second driven pulley 324. For example, the lifting driver 31 may be a servo motor.

[0066] In some embodiments, the lifting mechanism 3 drives the platform 2 to rise or fall in a single stroke S1, and the distance between adjacent temporary storage slots 20 is S2, where S1 = n * S2, and n is a positive integer. In other words, the lifting mode of the lifting mechanism 3 is designed to be an integer multiple of the distance between the temporary storage slots 20 in a single movement, ensuring that the temporary storage slots 20 can be aligned with the transfer slots 201, so as to facilitate the corresponding operations by the staff.

[0067] For example, when it is necessary to change the plate 100 in the first-layer transfer slot 201 to the second-layer transfer slot 201, after the plate 100 is pulled from the transfer slot 201 into the temporary storage slot 20, the lifting mechanism 3 drives the platform 2 to rise by one layer spacing in one lifting operation, which can ensure that the temporary storage slot 20 containing the plate 100 is aligned with the second-layer transfer slot 201 in one lifting operation.

[0068] For example, when it is necessary to change the board 100 in the first-level transfer slot 201 to the seventh-level transfer slot 201, after the board 100 is pulled from the transfer slot 201 into the temporary storage slot 20, the lifting mechanism 3 drives the platform 2 to rise six layers in one go, which can ensure that the temporary storage slot 20 containing the board 100 is aligned with the seventh-level transfer slot 201 in one lifting operation.

[0069] In some embodiments, the platform device further includes a baffle mechanism 4, which includes at least one baffle assembly for blocking the front side of the plate 100 in at least the temporary storage slot 20 to restrict the operator from pushing the plate 100 from the transfer slot 201 into the temporary storage slot 20 or pulling the plate 100 from the temporary storage slot 20 into the transfer slot 201.

[0070] The baffle assembly includes a baffle driver 41 and a baffle member 42. The baffle member 42 extends vertically and its height is not less than the height of the platform 2. The baffle driver 41 is mounted on the frame 1 and its output end is connected to the baffle member 42. It is used to drive the baffle member 42 to move in the left and right direction so that the baffle member 42 moves to the front side of the plate 100 in the temporary storage slot 20.

[0071] exist Figure 3 In the example shown, there are four sets of baffle assemblies. The four sets are respectively located at the upper left, lower left, upper right, and lower right ends of the front side of the frame 1, and are referred to as upper left baffle assembly 401, lower left baffle assembly 402, upper right baffle assembly 403, and lower right baffle assembly 404. The height of the baffle piece 42 in each baffle assembly is approximately half of the total lifting height of the platform 2. In actual operation, the corresponding baffle assembly can be activated to block the front side of the platform 2 according to the height of the platform 2.

[0072] In other embodiments, there are two sets of baffle assemblies, which are respectively located at the front left end and the front right end of the frame 1. In this case, the height of the baffle member 42 in each baffle assembly is approximately equivalent to the total lifting height of the platform 2.

[0073] exist Figure 4 In the example shown, the platform device also includes a locking plate mechanism 5. The locking plate mechanism 5 includes locking plate assemblies. The four locking plate assemblies are respectively referred to as the first locking plate assembly 501 and the second locking plate assembly 502. The first locking plate assembly 501 and the second locking plate assembly 502 are both installed on the platform 2 and are located on the front and rear sides of the platform 2, respectively. They are used to limit the plate 100 in the temporary storage slot 20 in the front and rear directions during the lifting process, so as to prevent the plate 100 in the platform 2 from shaking relative to the platform 2 during the lifting process and reduce the wear of the plate 100.

[0074] Two first locking plate assemblies 501 are located on the left and right sides of the front of the platform 2, respectively, and two second locking plate assemblies 502 are located on the left and right sides of the rear of the platform 2, respectively, with the first locking plate assemblies 501 and the second locking plate assemblies 502 arranged in a one-to-one correspondence. This arrangement ensures that the plate 100 is subjected to uniform force in the left and right directions, preventing the plate 100 from shaking due to uneven force.

[0075] like Figures 5 to 6As shown, both the first locking plate assembly 501 and the second locking plate assembly 502 include a locking plate driver 51 and a locking plate member 52. The locking plate member 52 extends vertically and covers all temporary storage slots 20 in the height direction. The locking plate driver 51 is mounted on the platform 2, and its output end is connected to the locking plate member 52. It is used to drive the locking plate member 52 to move in the left and right direction so that the locking plate member 52 moves to the front or rear side of the plate 100 in the temporary storage slot 20, so as to avoid the plate 100 in the platform 2 from shaking relative to the platform 2 during the lifting and lowering process of the platform 2, and reduce the wear of the plate 100.

[0076] The locking plate 52 includes a plate body 521, a stop portion 522, and an anti-static portion 523. The plate body 521 extends vertically, and multiple stop portions 522 extend horizontally and are fixedly connected to the plate body 521. Each stop portion 522 has an anti-static portion 523 fixed to the side facing the plate 100. The anti-static portion 523 may be made of Teflon material.

[0077] Figure 7 A front view of stage 2 is shown. Figure 7 The dotted lines between each temporary storage slot 20 are only to show the approximate boundary of each temporary storage slot 20. In reality, there is no such boundary. Each temporary storage slot 20 is vertically connected to each other to facilitate the user to place and remove the board 100.

[0078] Continue as Figure 7 Combination Figure 4 As shown, the platform 2 includes a base plate 21, side plates and bearing members. The two side plates are fixed to the base plate 21 at intervals and both extend in the vertical direction. On the opposite side of the two side plates, multiple bearing members are provided at intervals in the vertical direction. The bearing members on the two side plates are arranged one-to-one in the horizontal direction to form temporary storage slots 20 for supporting the plate 100.

[0079] The two side plates are designated as first side plate 22 and second side plate 23, respectively. The support member on the first side plate 22 is designated as first support member 24, and the support member on the second side plate 23 is designated as second support member 25. Specifically, the first side plate 22 and the second side plate 23 are fixed to the base plate 21 at intervals and both extend vertically. Multiple first support members 24 are fixed to the first side plate 22 at intervals vertically, and multiple second support members 25 are fixed to the second side plate 23 at intervals vertically. The first support members 24 and the second support members 25 are arranged one-to-one in the horizontal direction to jointly support the plate 100.

[0080] The support member includes a fixing part and a support part. The fixing part is fixed to the side plate, and the support part extends horizontally and is used to support the plate 100. Specifically, the first support member 24 includes a first fixing part and a first support part perpendicular to the first fixing part. The first fixing part is fixedly connected to the first side plate 22, and the first support part is used to support the plate 100. The second support member 25 includes a second fixing part and a second support part perpendicular to the second fixing part. The second fixing part is fixedly connected to the second side plate 23, and the second support part is used to support the plate 100.

[0081] Furthermore, the platform 2 also includes reinforcing members. Each of the aforementioned supporting parts has a reinforcing member located below it, and the reinforcing member is fixedly connected to both the supporting part and the side plate. Specifically, the two reinforcing members are referred to as the first reinforcing member 26 and the second reinforcing member, respectively. The first reinforcing member 26 is located below the first supporting part and is fixedly connected to both the first side plate 22 and the first supporting part to improve the load-bearing capacity of the first supporting part.

[0107] Step S622: If yes, push the plate 100 in the temporary storage slot 20 of the (Mm)th layer into the transfer slot 201 of the Mth layer.

[0108] In some embodiments, when N is 7 and M is 3, the method for changing the slot of the board includes the following steps: If the 4th layer temporary storage slot 20 is aligned with the 7th layer transfer slot 201 in the initial stage, which is equivalent to X being 4 and X being greater than M, then the stage 2 needs to be driven to rise by 1 layer spacing S2, which is equivalent to m being 0, so that the 3rd layer temporary storage slot 20 is aligned with the 7th layer transfer slot 201; then the board 100 in the 7th layer transfer slot 201 is pushed into the 3rd layer temporary storage slot 20; then the stage 2 is driven to fall by 4 layer spacing S2; at this time, the 3rd layer temporary storage slot 20 is aligned with the 3rd layer transfer slot 201, and then the board 100 in the 3rd layer temporary storage slot 20 is pushed into the 3rd layer transfer slot 201.

[0109] In some embodiments, when N is 7 and M is 3, the method for changing the slot of the board includes the following steps: If the 4th layer temporary storage slot 20 is aligned with the 7th layer transfer slot 201 in the initial stage, which is equivalent to X being 4 and X being greater than M, then the stage 2 needs to be driven to rise by 2 layer spacings S2, which is equivalent to m being 1, so that the 2nd layer temporary storage slot 20 is aligned with the 7th layer transfer slot 201, and then the board 100 in the 7th layer transfer slot 201 is pushed into the 2nd layer temporary storage slot 20; then the stage 2 is driven to fall by 4 layer spacings S2; at this time, the 2nd layer temporary storage slot 20 is aligned with the 3rd layer transfer slot 201, and then the board 100 in the 2nd layer temporary storage slot 20 is pushed into the 3rd layer transfer slot 201.

[0110] The above example illustrates a method for replacing one board slot at a time. The platform device provided in this application can also be used to replace any number of board slots, ranging from 2 to 10, at a time. The maximum number of board slots that can be replaced in a single operation is determined by the number of temporary storage slots 20 on the platform 2. For example, if the number of temporary storage slots 20 on the platform 2 is 7 layers, then 7 boards can be replaced in a single operation. The replacement method is roughly the same as that for replacing a single board, and will not be illustrated further here.

[0111] Furthermore, it should be noted that during all steps of raising or lowering the platform 2, the locking mechanism 5 is activated to lock the plate 100 within the corresponding temporary storage slot 20 to prevent the plate 100 from wobbling relative to the platform 2. Moreover, when it is not necessary to transfer the plate 100 from the platform 2 to the transfer trolley 200, the baffle mechanism 4 is activated to cover the front opening of the frame 1 and confine the plate 100 within the platform 2 to the corresponding temporary storage slot 20 to prevent operator error.

[0112] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
