Description

Technical Field

[0001] This utility model relates to the field of automated testing equipment technology, and in particular to a conveying and positioning mechanism. Background Technology

[0002] In the testing of chips and semiconductor devices, aging tests are a critical process for ensuring product reliability and stability. One of the core operations of this process is the precise loading and unloading of the device under test (DUT) and the aging board. Currently, to achieve this loading and unloading, the aging board must first be manually moved to a designated workbench, followed by manual handling. Typically, the aging board consists of a large and thick aluminum plate as the base, on which a PCB board and several flip-type sockets are mounted. Therefore, the entire aging board is quite heavy, making manual handling inefficient and posing a risk of injury from falling aging boards. Furthermore, due to the diverse sizes of aging boards, existing automated conveying devices are ill-suited to handling different sizes and lack the necessary positioning accuracy for high-precision loading and unloading. Therefore, developing a mechanism that can accurately simulate and replace manual operation, achieving automated conveying and precise positioning of aging boards, has become an urgent need to improve production efficiency, ensure product yield, and reduce overall costs.

[0018] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0019] The conveying and positioning mechanism provided by this utility model is applied to the aging test process of chips and semiconductor devices to realize the automated conveying and positioning of aging boards.

[0020] Reference Figure 1-3 The mechanism includes a test board 100, a moving channel 200, a working position 210, a positioning component 300, and a push-pull component 400, solving the problems of low efficiency, high labor intensity, and safety hazards associated with traditional manual handling of aging boards. The test board 100 is the aging board that carries the device under test. It typically consists of a heavy aluminum plate as the base plate 321, on which a PCB board and several flip-type sockets are mounted, resulting in a relatively large overall weight.

[0021] The moving channel 200 provides a moving path for the test board 100, ensuring that the test board 100 can smoothly move from one position to another along a predetermined trajectory. (Refer to...) Figure 2 The working position 210 is set at a predetermined position in the moving channel 200. This position is a key area for picking up and putting down materials. The test plate 100 can enter the working position 210 along the moving channel 200, and after completing the loading or unloading operation, it can be smoothly moved out of the working position 210 to continue the subsequent process.

[0022] Reference Figure 2 The positioning component 300 is set at the working position 210, and its core function is to position and stabilize the test board 100 that has arrived at the working position 210.

[0023] Reference Figure 5 The positioning component 300 includes a height-adjustable positioning part 310, which can move flexibly between a lowered position and a raised position. When the test board 100 has not yet reached the working position 210 or needs to be moved out of the working position 210, the positioning part 310 is in the lowered position, leaving sufficient space for the test board 100 to enter and exit, and avoiding interference. When the test board 100 moves along the moving channel 200 to the working position 210, the positioning part 310 immediately rises to the raised position. At this time, the positioning part 310 contacts the test board 100 and positions it, ensuring that the test board 100 remains stable at the working position 210 without positional shift or shaking, thereby providing a reference for subsequent device handling operations.

[0024] The push-pull assembly 400 drives the test plate 100 to move along the movement channel 200. In actual operation, when it is necessary to move the test plate 100 from a certain position on the movement channel 200 to the working position 210, the push-pull assembly 400 pulls the test plate 100 from the movement channel 200 into the working position 210. For example, refer to... Figure 7 When the loading operation begins, the unloaded or already tested aging board is located at the beginning of the moving channel 200. The push-pull assembly 400, through a pulling action, causes the aging board to move smoothly along the moving channel 200, eventually reaching the working position 210, awaiting loading or unloading by the loading / unloading robot. Conversely, referring to... Figure 8 , 9 When the work at work position 210 is completed, and the test board 100 needs to be moved out of work position 210 for the next process or returned to the storage area, the push-pull assembly 400 switches to push mode, pushing the test board 100 from work position 210 to the movement channel 200, so that it continues to move along the movement channel 200 to the subsequent position.

[0025] Through the coordinated operation of the aforementioned components, this conveying and positioning mechanism achieves automated conveying and positioning of aging boards. The entire process eliminates the need for manual handling of heavy aging boards, significantly reducing labor intensity and eliminating the safety risk of injury from falling aging boards. Simultaneously, the automated conveying and positioning method significantly improves operational efficiency, shortens the time cycle for each loading and unloading, ensures product quality and reliability, and effectively reduces overall production costs.

[0026] In one specific embodiment, refer to Figure 5The positioning assembly 300 also includes a lifting drive unit 320, which is connected to the positioning unit 310 and is used to drive the positioning unit 310 to move up and down between a lowered position and a raised position. The lifting drive unit 320 can adopt various driving forms such as a motor, cylinder, or hydraulic cylinder, and drives the positioning unit 310 to achieve the lifting action through power output. The specific structure of the positioning unit 310 includes a support plate 311 and clamping blocks 312 disposed at both ends of the support plate 311. The support plate 311 is a load-bearing planar structure, whose main function is to support the bottom of the test plate 100 and provide a stable supporting force for the test plate 100. The clamping blocks 312 are respectively disposed at both ends of the support plate 311, and their function is to clamp the two side edges of the test plate 100, apply a constraint force to the test plate 100 from the side, and prevent the test plate 100 from moving or rotating in the horizontal direction.

[0027] When the test plate 100 moves along the moving channel 200 and reaches the working position 210, the lifting drive unit 320 is activated, driving the support plate 311 and clamping blocks 312 to rise synchronously. During the rising process, the support plate 311 gradually approaches and finally supports the bottom of the test plate 100. At the same time, the clamping blocks 312 located at both ends of the support plate 311 also rise with the support plate 311. When it rises to a predetermined height, the inner side of the clamping blocks 312 fits tightly against the two side edges of the test plate 100, and the clamping blocks 312 apply an appropriate clamping force to the sides of the test plate 100, firmly fixing the test plate 100 to the support plate 311. For example, in the loading stage of aging test, the pick-and-place robot needs to accurately place the chip under test into the flip-type socket on the aging board. At this time, the aging board must remain absolutely stable. Any slight positional deviation may cause the chip placement to fail or damage the socket. The positioning component 300, through the coordinated action of the support plate 311 and the clamping block 312, ensures the positioning accuracy of the aging board and guarantees the smooth progress of the loading operation.

[0028] To accommodate test plates 100 of different sizes, in another embodiment, refer to... Figure 5Of the clamping blocks 312 at both ends of the support plate 311, at least one clamping block is a movable clamping block 313, which is movably mounted on the support plate 311. The movable clamping block 313 can move along the length of the support plate 311, and the distance between the two clamping blocks can be changed by adjusting the position of the movable clamping block 313. For example, when processing a test plate 100 with a smaller width, the operator or an automatic adjustment mechanism moves the movable clamping block 313 towards the center of the support plate 311, reducing the distance between the two clamping blocks to match the width of the test plate 100. When processing a test plate 100 with a larger width, the movable clamping block 313 is moved outward from the support plate 311 to increase the clamping block distance to accommodate a wider test plate 100. The movement of the movable clamping block 313 can be manually adjusted by fixing its position with a bolt locking mechanism, or it can be automatically adjusted by a motor-driven or cylinder-driven method.

[0029] Reference Figure 5 A preferred structure of the lifting drive unit 320 includes a base plate 321, a fixing rod 322, a first motor 323, a drive plate 324, and a support side plate 325. The base plate 321 serves as the basic mounting surface of the lifting drive unit 320, providing stable support for the entire drive mechanism. The fixing rod 322 is mounted on the base plate 321 and is typically fixed using bolts or welding. The fixing rod 322 extends upwards perpendicular to the surface of the base plate 321. The first motor 323 is fixedly connected to the base plate 321 via the fixing rod 322, which supports and positions the first motor 323, ensuring that the first motor 323 is securely installed and accurately positioned. The drive plate 324 is positioned between the fixing rod 322 and the first motor 323, and is connected to the output end of the first motor 323. The first motor 323 can be a lead screw motor, a rack and pinion motor, or other types of linear drive motors. When the first motor 323 is running, its output end converts the rotational motion into the linear motion of the drive plate 324 through a transmission mechanism such as a lead screw and a gear rack. The drive plate 324 can move up and down relative to the base plate 321 along the direction of the fixed rod 322.

[0030] The support side plate 325 is fixedly connected to the drive plate 324, and the support side plate 325 is also slidably connected to the base plate 321. The slidable connection can be achieved by setting a guide rail 411 on the base plate 321 and installing a slider 412 that cooperates with the guide rail 411 on the support side plate 325, or by using other sliding pair structures.

[0031] The supporting side plate 325 is also fixedly connected to the supporting plate 311, which is the component in the positioning part 310 used to support the test plate 100. When the first motor 323 drives the drive plate 324 to rise and fall, since the drive plate 324 is fixedly connected to the supporting side plate 325, the rising and falling movement of the drive plate 324 directly drives the supporting side plate 325 to rise and fall synchronously. Under the constraint of sliding connection with the base plate 321, the supporting side plate 325 moves smoothly in the vertical direction, and then, through its fixed connection with the supporting plate 311, drives the entire positioning part 310 to rise and fall.

[0032] Reference Figure 4 The push-pull assembly 400 includes a push-pull drive unit 410 and a push-pull unit 420. The push-pull unit 420 is the actuator that directly contacts the test plate 100 and applies push-pull force. The push-pull unit 420 includes a push-pull block 423 and a lifting drive member 424. The lifting drive member 424 is connected to the push-pull block 423 and can be in the form of a small cylinder, electric push rod, etc., to drive the push-pull block 423 to move vertically. The lifting of the push-pull block 423 allows it to contact or disengage from the test plate 100. When the push-pull block 423 rises to a certain height, it contacts the edge or bottom of the test plate 100, at which point it can apply push or pull force to the test plate 100. When the push-pull block 423 descends to a lower position, it disengages from the test plate 100 and does not interfere with the movement of the test plate 100.

[0033] The push-pull drive unit 410 is connected to the push-pull unit 420. The function of the push-pull drive unit 410 is to drive the entire push-pull unit 420 to move along the extension direction of the moving channel 200. During operation, the lifting drive unit 424 first drives the push-pull block 423 to rise, so that the push-pull block 423 contacts the test plate 100, establishing a path for the transmission of push and pull forces. Then, the push-pull drive unit 410 is activated, driving the push-pull unit 420 to move along the extension direction of the moving channel 200. Since the push-pull block 423 is in contact with the test plate 100, the movement of the push-pull unit 420 is transmitted to the test plate 100 through the push-pull block 423, thereby pushing or pulling the test plate 100 to move along the moving channel 200.

[0034] In the further optimized structure of the push-pull section 420, refer to Figure 4 The push-pull section 420 also includes an extension plate 421. One end of the extension plate 421 is connected to the output end of the lifting drive 424, and the other end extends along the extension direction of the moving channel 200. The extension plate 421 provides a mounting base for the push-pull block 423, which is connected to the extension plate 421 and protrudes from the surface of the extension plate 421 in a vertical direction perpendicular to the moving channel 200. The design of the push-pull block 423 protruding from the surface of the extension plate 421 allows the push-pull block 423 to contact the test plate 100 more effectively.

[0035] Reference Figure 7 When the test plate 100 needs to be pulled, the push-pull part 420 moves to the far end of the test plate 100, i.e., the rear end of the test plate 100. At this time, the lifting drive 424 drives the extension plate 421 and the push-pull block 423 mounted on the extension plate 421 to rise together. During the rising process, the portion of the push-pull block 423 protruding from the surface of the extension plate 421 gradually approaches the rear edge of the test plate 100. When it rises to a predetermined height, the protruding portion of the push-pull block 423 abuts tightly against the rear edge of the test plate 100. Subsequently, the push-pull drive 410 drives the push-pull part 420 to move towards the working position 210. The protruding portion of the push-pull block 423 applies a pulling force to the rear edge of the test plate 100. Due to the reliable abutment between the push-pull block 423 and the edge of the test plate 100, the pulling force is effectively transmitted to the test plate 100, thereby pulling the test plate 100 along the moving channel 200 to the working position 210.

[0036] Reference Figure 8 , 9 When the test plate 100 needs to be pushed, the lifting drive 424 drives the push-pull block 423 to rise to the same height as the test plate 100. At this time, the upper surface of the push-pull block 423 is at the same level as the bottom or side of the test plate 100. The push-pull drive 410 drives the push-pull part 420 to move along the moving channel 200. The push-pull block 423 applies a pushing force to the test plate 100, pushing the test plate 100 forward.

[0037] Reference Figure 4 To enhance the cushioning performance and protect the test plate 100 during the push-pull process, a compression spring 422 is provided between the extension plate 421 and the push-pull block 423. One end of the compression spring 422 is connected to or abuts against the extension plate 421, and the other end is connected to or abuts against the push-pull block 423. When the push-pull block 423 applies a pushing or pulling force to the test plate 100, if it encounters significant resistance or impact, the compression spring 422 can absorb some of the energy, preventing the push-pull block 423 from damaging the edge of the test plate 100.

[0038] Reference Figure 4One embodiment of the push-pull drive unit 410 includes a guide rail 411 arranged along the extension direction of the moving channel 200, and a slider 412 slidably arranged on the guide rail 411. The guide rail 411 provides a moving trajectory for the slider 412, ensuring that the slider 412 moves linearly along the extension direction of the moving channel 200. The push-pull drive unit 410 also includes a second motor 413 and a synchronous belt 414 driven by the second motor 413. The second motor 413 drives the synchronous belt 414 to rotate through a transmission mechanism. The synchronous belt 414 is arranged around the output wheel and driven wheel of the second motor 413. The slider 412 is fixedly connected to the synchronous belt 414 by a pressure block 415. The pressure block 415 firmly fixes the slider 412 to the synchronous belt 414, so that when the second motor 413 drives the synchronous belt 414 to move, the movement of the synchronous belt 414 directly drives the slider 412 to slide along the guide rail 411.

[0039] The push-pull part 420 is mounted on the slider 412. Various components of the push-pull part 420, such as the extension plate 421, the lifting drive component 424, and the push-pull block 423, are fixed to or connected to the slider 412. When the second motor 413 drives the synchronous belt 414, the synchronous belt 414 causes the slider 412 to reciprocate linearly along the guide rail 411. The movement of the slider 412 then causes the push-pull part 420 mounted on it to move together, thereby realizing the push-pull action on the test plate 100. For example, when the second motor 413 rotates in the forward direction and the synchronous belt 414 runs in one direction, the slider 412 moves along the guide rail 411 towards the working position 210. The push-pull part 420 moves with the slider 412, and the push-pull block 423 applies a pulling or pushing force to the test plate 100, moving the test plate 100 towards the working position 210. When the second motor 413 rotates in the opposite direction, the synchronous belt 414 runs in the opposite direction, the slider 412 moves in the opposite direction along the guide rail 411, and the push-pull part 420 returns to the initial position or moves to the other end of the test plate 100, ready to perform the next push-pull action.

[0040] Reference Figure 3 , 6To support and guide the test plate 100 along the moving channel 200, the conveying and positioning mechanism also includes conveying tracks 220 located on both sides of the moving channel 200. Each conveying track 220 includes a support 221 and a track plate 222 mounted on the support 221. The support 221 provides a stable mounting base for the track plate 222, and rollers 2221 are provided on the side of the track plate 222 facing the moving channel 200. The two edges of the test plate 100 rest on the rollers 2221 of the conveying tracks 220 on both sides. The rollers 2221 are mounted on the track plate 222 via bearings and can rotate freely. When the test plate 100 is placed on the rollers 2221, the weight of the test plate 100 is borne by the rollers 2221, which provide support for the test plate 100. Because the roller 2221 can rotate, when the push-pull assembly 400 drives the test plate 100 to move along the moving channel 200, the friction between the test plate 100 and the roller 2221 is minimal. The roller 2221 rotates with the movement of the test plate 100, thereby guiding the test plate 100 to move smoothly along the moving channel 200, reducing resistance during the movement process and improving conveying efficiency.

[0041] The track plate 222 also includes a limiting block 2222 disposed on the side away from the roller 2221, with the edge of the test plate 100 located between the roller 2221 and the limiting block 2222. The function of the limiting block 2222 is to limit the lateral movement range of the test plate 100 and prevent the test plate 100 from shifting laterally or detaching from the roller 2221 during movement.

[0042] Reference Figure 6 At least one lateral positioning device 2223 is provided on the track plate 222 corresponding to the working position 210. The lateral positioning device 2223 has a retractable positioning end. The lateral positioning device 2223 can be driven by a cylinder, electric push rod, or other means, and the positioning end is connected to the output end of the drive mechanism. When the test plate 100 has not yet reached the working position 210 or is in the process of moving, the positioning end is in a retracted state, retracted inside the track plate 222 or away from the moving channel 200, and will not interfere with the movement of the test plate 100. When the test plate 100 moves to the working position 210, the lateral positioning device 2223 is activated, and the positioning end extends towards the moving channel 200. The length of the extended positioning end is precisely designed so that the end of the positioning end just abuts against the side edge of the test plate 100.

[0043] After the positioning end abuts against the side edge of the test plate 100, it cooperates with the aforementioned positioning component 300 to position and fix the test plate 100. The positioning component 300 supports the bottom of the test plate 100 through the support plate 311 and clamps the two sides of the test plate 100 through the clamping block 312, thereby achieving positioning of the test plate 100 in the vertical direction and part of the horizontal direction. The positioning end of the lateral positioning device 2223 applies a constraint force from the side of the test plate 100, further restricting the lateral movement of the test plate 100, and together with the positioning component 300, constitutes a comprehensive positioning and fixation of the test plate 100.

[0044] For example, in the loading and unloading stages of aging tests, the robotic arm performs high-precision operations on the chips on the aging board, which must remain absolutely stationary and precisely positioned. The coordinated action of the positioning component 300 and the lateral positioning device 2223 ensures the positioning accuracy of the aging board at the working position 210. Even if the robotic arm moves rapidly above the aging board and performs loading and unloading actions, the aging board will not experience any positional shift, guaranteeing the accuracy and success rate of chip loading and unloading. This effectively avoids quality problems such as incorrect chip placement and socket damage caused by unstable aging board positioning, improving the overall yield and production efficiency of aging tests. The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
