Description

Technical Field

[0001] This application relates to the field of transfer technology, specifically to a fixed transfer mechanism. Background Technology

[0002] Testing technology for packaged chips is a crucial technology in the electronics industry for ensuring product quality and accelerating production processes. Existing packaged chips are often mounted in a herringbone fixture, on which a pin plate is detachably installed. The pin plate provides power to the packaged chip for performance testing. In use, the assembly of the herringbone fixture and pin plate is collectively referred to as the complete fixture. Specifically, the complete fixture is housed within a drawer, and the complete fixture is detachably connected to the drawer, preferably via screws.

[0003] The existing announcement number is CN108687552A, entitled "A Compact Pneumatic Tooling Fixture," belonging to the mechanical field. This tooling includes a fixed base plate, a push cylinder mounting base, a main push cylinder, a fixture retainer, a fixture clamping section, a downward auxiliary cylinder, a workpiece positioning block, a main downward cylinder, a front support block, a rear support block, and a workpiece. The cooperation between the fixture clamping section and the front and rear support blocks expands the actual clamping range, meeting the actual processing requirements of most parts. The entire fixture achieves automatic clamping and releasing under the action of the cylinders, improving the reliability of the fixture and increasing the efficiency of workpiece insertion and removal during operation. The entire process is pneumatically controlled, avoiding incomplete workpiece clamping and reducing errors during operation. The clamping section and positioning block can be adjusted according to workpiece specifications, expanding the applicability of the fixture.

[0004] While existing pneumatic tooling has solved the problem of fixing individual workpieces, it is difficult to solve the problem of fixing components. In the field of packaged chip transfer, when the full fixture is separated from the drawer, the screws fixing the two need to be loosened. If only the drawer is fixed in this process, the full fixture may shift with the rotation of the screws when the screws are turned, or even be thrown out of the drawer with the rotation of the screwdriver bit.

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

These terms are used solely for the convenience of describing this application and for simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "multiple" and "several" also appear. "Multiple" means at least two, and can be two, three, etc., while "several" means at least one, and can be one, two, three, etc., unless otherwise explicitly specified.

[0037] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, if a description such as "above" or "below" the second feature appears, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0039] The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0040] In some embodiments of this application, reference is made to Figure 1-3As shown, this application provides a fixed transfer mechanism for fixing and transferring a load. Since the load is fixed to the fixed transfer mechanism during the transfer process, it facilitates the implementation of operational procedures. The load has a receiving groove for loading the part to be clamped. In this specific embodiment, the load is a drawer 112, and the part to be clamped is a full clamp 40. Figure 8 As shown, the aforementioned complete clamp 40 specifically includes a fishbone clamp 41 and a needle plate 42. The fishbone clamp 41 and the needle plate 42 are detachably connected together by screws, and the fishbone clamp 41 and the needle plate 42 as a whole are referred to as the complete clamp 40. A receiving slot is provided on the upper surface of the drawer 112, and several complete clamps 40 are stored in the receiving slot.

[0041] The fixed transfer mechanism includes a fixed transfer module 31, a transfer platform 32, a gripping module 33, and a fixing module. A fixed station a is set on the transfer platform 32. The gripping module 33 transfers the drawer 112, which is loaded with the full clamp 40, to the fixed station a along a first direction (i.e., the x-axis direction), transferring the drawer 112 onto the transfer platform 32. After the drawer 112 moves to the fixed station a, it is clamped and pressed down to secure it. The transfer platform 32 is mounted on the fixed transfer module 31, and the fixing module is set on the transfer platform 32. Driven by the fixed transfer module 31, the transfer platform 32 moves the fixing module along a second direction (specifically, the y-axis direction).

[0042] Meanwhile, the fixing module includes at least two clamping modules and a pressing module 34. The clamping modules include a first clamping module 35 and a second clamping module 36. The pressing module 34, the first clamping module 35, and the second clamping module 36 are adapted to fit with the drawer 112 and the full clamp 40 on the fixed station a. The pressing module 34, the first clamping module 35, and the second clamping module 36 fix the drawer 112 and the full clamp 40 loaded on the drawer 112 to the fixed station a. The specific fixing method of the pressing module 34, the first clamping module 35, and the second clamping module 36 includes that the first clamping module 35 and the second clamping module 36 respectively abut against the two sides of the drawer 112, and the pressing module 34 moves longitudinally into the receiving groove to press the full clamp 40 into the drawer 112. In this solution, the longitudinal direction is a straight line direction perpendicular to the x-axis and y-axis respectively.

[0043] The number of clamping modules 34 is at least two. The number of clamping modules 34 matches the number of full clamps 40 on the drawer 112. The clamping modules 34 and the full clamps 40 on the drawer 112 are clamped one-to-one, so that each full clamp 40 is fixed independently.

[0044] Furthermore, combined Figure 6As shown, the gripping module 33 includes a linear driver 331, a power transmission plate 332, and a gripper 333. The power transmission plate 332 is disposed on the power output end of the linear driver 331, and the gripper 333 is mounted on the power transmission plate 332. Driven by the linear driver 331, the power transmission plate 332 and the gripper 333 move along the x-axis. Since the gripper 333 can grip the drawer 112, the drawer 112 can also move along the x-axis. The fixed station a is located on the moving path of the drawer 112.

[0045] Specifically, the gripper 333 is mounted on the power transmission plate 332. After the gripper 333 grips the drawer 112, the drawer 112 rests on the power transmission plate 332. The drawer 112 has a gripping block 1121 that is adapted to the gripper 333. The gripper 333 moves the drawer 112 by forming a connection structure with the gripping block 1121.

[0046] In this design, the gripper 333 is a pneumatic gripper, and the gripping block 1121 is a handle. Although the gripper 333 can engage the handle, the center of gravity of the drawer 112 is far from the point where the gripper 333 and the gripping block 1121 meet. This can easily cause the drawer 112 to tilt with the point of engagement between the gripper 333 and the gripping block 1121 as its origin, making it difficult for the pneumatic gripper to maintain the balance of the drawer 112. In this design, the power transmission plate 332 is located below the drawer 112. The power transmission plate 332 supports the drawer 112 to ensure its stable position.

[0047] In some embodiments of this application, reference is made to Figure 7 As shown, the clamping module 34 includes a pressure plate 341, a lifting driver 343, a bracket 344, and a cylinder 345. The lifting driver 343 is connected to the pressure plate 341, and the cylinder 345 is connected to the lifting driver 343 via the bracket 344. The cylinder 345 drives the lifting driver 343 and the pressure plate 341 to move closer to the drawer 112, and the lifting driver 343 drives the pressure plate 341 to move longitudinally closer to the full clamp 40 loaded on the drawer 112.

[0048] The pressure plate 341 is provided with at least two clamping blocks 342 that abut against the full clamp 40. The clamping blocks 342 are made of elastic material. The pressure plate 341 is moved above the full clamp 40 by the cylinder 345 and driven by the lifting drive 343. The pressure plate 341 gradually approaches the full clamp 40 until the clamping blocks 342 press against the full clamp 40. The clamping blocks 342 and the drawer 112 press against each other, confining the full clamp 40 within the receiving groove. In addition, the elastic clamping blocks 342 can absorb the supporting force generated when the clamping blocks 342 and the full clamp 40 are pressed together, thereby protecting the full clamp 40 from damage.

[0049] Furthermore, the pressure plate 341 has a slot 3411, making it U-shaped. The pressure plate 341 has two legs 3412 that mate with the slot 3411. The two opposite ends of the slot 3411 on the pressure plate 341 are the legs 3412. In this design, the legs 3412 are the two ends of the U-shaped pressure plate 341, and the slot 3411 is the empty space within the U-shaped pressure plate 341. The clamping block 342 is mounted on the legs 3412. The longitudinal projection of the slot 3411 falls on the full clamp 40. Longitudinally, the projected area of ​​the legs 3412 on the full clamp 40 is much smaller than the projected area of ​​the slot 3411 on the full clamp 40. Since the full clamp 40 in this design has multiple screws, to facilitate tightening the screws on the full clamp 40 of the fixed transfer mechanism, the projected area of ​​the slot 3411 on the full clamp 40 is large, which reduces the interference area.

[0050] In this scheme, the number of clamping blocks 342 is preferably two. In order to reduce the projected area of ​​the support leg 3412 on the full clamp 40, the clamping blocks 342 also need to be able to stably clamp the full clamp 40. The two clamping blocks 342 apply pressure to the full clamp 40 at two points to prevent the full clamp 40 from tilting.

[0051] In some embodiments of this application, two clamping modules are arranged opposite each other on both sides of the linear actuator 331. Each clamping module includes a driving member and a clamping block 361, with the driving member driving the clamping block 361 close to the drawer 112 on the fixed workstation a. Preferably, the pressing module 34 and the first clamping module 35 are located on the same side of the linear actuator 331. The driving direction of the cylinder 345 is consistent with the driving direction of the driving member. The pressing module 34 and the first clamping module 35 are independent of each other.

[0052] The specific workflow of this fixed transfer agency includes:

[0053] First, the drawer 112, which is loaded with the full fixture 40, is transferred to the fixed station a. The clamping module 34 and the clamping module 35 work, so that the clamping module 34 clamps the full fixture 40 and the clamping module 35 clamps the drawer 112.

[0054] Subsequently, the fixed transfer module 31 drives the drawer 112 fixed on the fixed station a to move along the y-axis. During this process, the clamping module 34 separates from the clamping component. At the same time, the clamping module 35 always keeps the drawer 112 clamped.

[0055] Since the fixed transfer mechanism needs to separate the full clamp 40 from the drawer 112, the clamping module 34 and the clamping module are required to operate independently. Specifically, separating the clamping module 34 from the full clamp 40 includes: the clamping block 342 moving away from the full clamp 40; more specifically, the height of the clamping block 342 is higher than the receiving groove; and the cylinder 345 driving the pressure plate 341 away from the full clamp 40. At least the longitudinal projection of the pressure plate 341 does not overlap with the full clamp 40, to prevent interference between the full clamp 40 and the pressure plate 341 when the full clamp 40 is removed from the drawer 112.

[0056] Furthermore, the number of clamping modules 34 is at least two, with a first clamping module 35 located between the two clamping modules 34. The number of clamping modules 34 corresponds to the number of clamps 40 that can be loaded on the drawer 112, ensuring a one-to-one correspondence between the clamping modules 34 and the clamps 40 on the drawer 112. Preferably, the clamping modules are positioned corresponding to the center position of the drawer 112. For example, the center of the drawer 112 is located on the power axis of the drive member on the clamping module, so that when the clamping module clamps the drawer 112, it can stably hold the drawer 112.

[0057] In addition, in this solution, the gripping module 33 adopts a gripper cylinder to form a connection structure with the drawer 112. The gripper cylinder can restrict the movement of the drawer 112 in the x-axis direction and longitudinal direction. Through the gripping module 33 and the clamping module, the drawer 112 can be limited in three directions, thereby achieving stable fixation of the drawer 112.

[0058] Furthermore, refer to Figure 4 , 5 As shown in Figure 8, the transfer platform 32 is equipped with a platform 37, and the platform 37 and the second clamping module 36 are located on the same side of the fixed station. The platform 37 is used to temporarily store the full clamp 40. In this design, the full clamp 40 is a single clamp. The platform 37 can hold the fishbone clamp 41 and the needle plate 42 respectively. Specifically, the platform 37 includes a table surface 371. A clearance groove 372 is provided on the side of the table surface 371 near the fixed station to accommodate the clamping block 361 of the second clamping module 36. The clamping block 361 can extend or retract into the clearance groove 372. By providing the clearance groove 372, the clamping block 361 can easily abut against the drawer 112, while also making the layout of the platform 37 and the second clamping module 36 more compact.

[0059] The above embodiments are used to further illustrate this application, but do not limit this application to these specific implementations. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be understood as falling within the protection scope of this application.
