Description

Technical Field

[0001] This utility model relates to the field of product testing technology, and in particular to a manual microscopic inspection production line. Background Technology

[0002] For some small, precision products on the production line, such as chips or DBC substrates, quality is typically assessed manually using microscopy, while electron microscopy is used for inspection. The electron limiting lens is positioned at a fixed microscopic inspection station.

[0003] In continuous production lines, products are typically transported to the vicinity of the microscopic inspection station using pallets. They are then manually moved to the inspection station, where they are inspected sequentially under an electron microscope. Defective products are removed, while qualified products are retained and then transferred to the next production process.

[0004] With the increase in product output and the improvement of quality control requirements, the accuracy and efficiency of manual microscopic inspection are also getting higher and higher. At present, the efficiency of manual microscopic inspection cannot meet the needs of production cycle. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a manual microscopic examination production line, thereby improving the efficiency and accuracy of manual microscopic examination.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A manual microscopic examination production line, comprising:

[0008] The main conveyor line is used to convey a pallet carrying products, on which two rows of products are placed side by side. The pallet includes sliding edges that are arranged opposite to each other and parallel to each other along a first direction, and limiting edges that are arranged opposite to each other along a second direction. The first direction is perpendicular to the second direction, and the length direction of the sliding edges is consistent with the arrangement direction of the single row of products.

[0009] The workbench is located on one side of the main conveyor line. An electron microscope is installed on the workbench. The workbench is provided with a bottom wall and two sets of first inner walls and second inner walls. The first inner walls and second inner walls are perpendicular to each other. The first inner walls, second inner walls and bottom wall enclose and form a rectangular groove with the opening facing upward.

[0010] The first side conveyor line is located on one side of the workbench along the length of the first inner wall. The first end of the first side conveyor line is connected to the main conveyor line, and the tail end of the first side conveyor line corresponds to a second inner wall.

[0011] The second side conveyor line is located on the other side of the workbench along the length of the first inner wall. The first end of the second side conveyor line is connected to the main conveyor line, and the tail end of the second side conveyor line corresponds to another second inner wall.

[0012] During microscopic examination, the first side conveyor line receives the tray from the main conveyor line. The tray at the end of the first side conveyor line is manually moved to the rectangular groove, so that a sliding edge slides relative to the first inner wall under the guidance of the first inner wall, respectively guiding the two rows of products into and out of the field of view of the electron microscope. The tray after inspection is conveyed to the main conveyor line from the end of the second side conveyor line.

[0013] As a further improvement to the above technical solution:

[0014] Two second inner walls are used to limit the travel of the tray along the length of the first inner wall. When the tray is at both ends of the travel, the second inner walls limit the limiting edge, so that the first product in a row is in the field of view of the electron microscope.

[0015] The limiting edges are parallel to each other and perpendicular to the sliding edge. One limiting edge contacts the second inner wall and slides relative to it, which is used to guide the movement of the tray so that the field of view of the electron microscope can switch between the two rows of products.

[0016] The bottom wall is a plane, and the roughness of the plane is less than or equal to Ra 1.6 μm.

[0017] It also includes a slide block, which includes a plate-shaped body. The plate-shaped body is rectangular and has multiple notches along its edges. A buffer plate is installed along the edge of the plate-shaped body, avoiding the notches. The upper edge of the buffer plate is higher than the upper surface of the plate-shaped body and forms a limiting groove adapted to the tray with the upper surface of the plate-shaped body. When the tray is placed in the limiting groove, the notches are located below the tray. The lower surface of the plate-shaped body slides against the bottom wall. The sliding edge and the limiting edge indirectly contact the rectangular groove through the buffer plate.

[0018] The lower surface of the plate-shaped body is equipped with multiple omnidirectional balls, which slide in conjunction with the bottom wall to provide sliding support for the plate-shaped body.

[0019] The conveying directions of the first side conveyor line and the second side conveyor line are perpendicular to the conveying direction of the main conveyor line. A reversing mechanism is provided at the main conveyor line corresponding to the first side conveyor line and the second side conveyor line. A first blocking mechanism for blocking the pallet is provided on the main conveyor line downstream of the reversing mechanism, so that the pallet is located directly above the reversing mechanism.

[0020] The reversing mechanism includes a first mounting frame fixedly installed on the frame of the main conveyor line, and a first bracket slidably installed on the first mounting frame in a vertical direction. A first cylinder for driving the first bracket to lift and lower is fixedly installed on the first mounting frame. A first motor is fixedly installed on the first bracket. A horizontal conveyor belt is rotatably installed on the first bracket. The first motor is connected to the horizontal conveyor belt in a transmission connection. The conveying direction of the horizontal conveyor belt is perpendicular to the conveying direction of the main conveyor line.

[0021] Wherein, after the first cylinder drives the first bracket to descend, the conveying surface of the horizontal conveyor belt is lower than the conveying surface of the main conveyor line. After the first cylinder drives the first bracket to rise, the conveying surfaces of the first side conveyor line and the second side conveyor line are flush with the conveying surface of the horizontal conveyor belt and higher than the conveying surface of the main conveyor line.

[0022] Multiple workbenches are spaced apart along the conveying direction of the main conveyor line.

[0023] The first side conveyor line is provided with a buffering mechanism for buffering multiple trays vertically, and a second blocking mechanism located on the first side conveyor line downstream of the buffering mechanism. The second blocking mechanism is used to block the trays so that the trays are located in the buffering mechanism.

[0024] The buffer mechanism includes a second mounting frame fixedly installed on the frame of the first side conveyor line, a second motor fixedly installed on the second mounting frame, and a second bracket for lifting the tray slidably installed on the second mounting frame along the vertical direction. The second motor is connected to the second bracket for driving the second bracket to lift and lower, thereby driving the tray to lift and lower.

[0025] It also includes a pair of second cylinders fixedly installed on both sides of the first side conveyor line. The moving end of the second cylinder is equipped with a pallet. The second cylinder is used to drive the pallet to extend and retract in the horizontal direction, intermittently supporting the pallet, so that the supported pallet is above the conveying surface of the first side conveyor line and avoids pallets located on the first side conveyor line.

[0026] The first side conveyor line corresponding to the buffer mechanism is provided with multiple vertical guide structures, which form guide grooves corresponding to the edge of the tray. A sensor group for detecting the number of trays is installed on the guide structure.

[0027] The beneficial effects of this utility model are as follows:

[0028] This utility model has a compact and reasonable structure and is easy to operate. By setting up a manual microscopic inspection station on one side of the main conveyor line of the conveyor tray, and extending a first side conveyor line and a second side conveyor line on the side of the main conveyor line to receive the trays of products to be inspected and to move the inspected trays to the main conveyor line, the handling time of manual microscopic inspection is shortened. By setting a rectangular groove on the worktable to guide the movement of the tray, it helps the operator to accurately move the product to the field of view of the electron microscope, thereby improving the efficiency and accuracy of manual microscopic inspection.

[0029] This utility model also has the following advantages:

[0030] (1) A row of products is guided by the first inner wall in the rectangular groove to move the field of view of the electron microscope relative to the products. The second inner wall limits the two ends of the travel of the tray and positions the head of each row of products. This facilitates the rapid switching and positioning of the two rows of products and improves the efficiency of manual microscopic examination.

[0031] (2) A slide block is slidably set in the rectangular groove. A notch is set on the slide block to facilitate the support and placement of the pallet. The smoothness of the pallet sliding on the bottom wall can be adjusted by changing the sliding fit between one slide block and the bottom wall. There is no need to impose higher requirements on each pallet, and the wear on the bottom wall is reduced. A buffer plate is set on the slide block to place the positioning pallet while avoiding excessive impact with the rectangular groove when the pallet slides, which would cause vibration and change the position of the product on the pallet.

[0032] (3) Multiple worktables are set at intervals along the conveying direction of the main conveyor line. When the production cycle of the product is fast, the output of manual microscopic inspection is increased to match the output of the product and ensure the quality of product inspection.

[0033] (4) A buffer mechanism with multiple trays vertically buffered is set on the first side conveyor line to improve the flexibility of the manual microscopic inspection conveyor line. At the same time, when a main conveyor line is matched with multiple worktables, it is convenient to adjust the workload between multiple worktables, so that the inspection efficiency matches the output of the products.

[0034] (5) When there are many stacked trays, the guide structure plays a guiding and protective role from the outside of the trays. At the same time, the sensor group is installed to detect whether there are trays on the buffer mechanism and whether the number of trays has reached or is close to the limit of the buffer quantity, so as to ensure the safety of the buffer mechanism and to report the current material storage status of the microscopic inspection station to the manual microscopic inspection production line.

[0061] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0062] Example 1:

[0063] like Figures 1-3 As shown, the manual microscopic examination production line of this embodiment includes a main conveyor line 2, a worktable 9, a first side conveyor line 7, and a second side conveyor line 4.

[0064] The main conveyor line 2 is used to convey the pallet 6 carrying the products. Two rows of products are placed side by side on the pallet 6. The pallet 6 includes a sliding edge 61 that is arranged opposite to each other and parallel to each other along a first direction, and a limiting edge 62 that is arranged opposite to each other along a second direction. The first direction is perpendicular to the second direction, and the length direction of the sliding edge 61 is consistent with the arrangement direction of the single row of products.

[0065] The workbench 9 is located on one side of the main conveyor line 2. An electron microscope 8 is installed on the workbench 9. The workbench 9 is provided with a bottom wall 93 and two sets of first inner walls 91 and second inner walls 92. The first inner walls 91 and second inner walls 92 are perpendicular to each other. The first inner walls 91, second inner walls 92 and bottom wall 93 enclose and form a rectangular groove with the opening facing upward.

[0066] The first side conveyor line 7 is located on one side of the workbench 9 along the length direction of the first inner wall 91. The first end of the first side conveyor line 7 is connected to the main conveyor line 2, and the tail end of the first side conveyor line 7 corresponds to a second inner wall 92.

[0067] The second side conveyor line 4 is located on the other side of the workbench 9 along the length of the first inner wall 91. The first end of the second side conveyor line 4 is connected to the main conveyor line 2, and the tail end of the second side conveyor line 4 corresponds to another second inner wall 92.

[0068] During microscopic examination, the first side conveyor line 7 receives the tray 6 from the main conveyor line 2. The tray 6 at the end of the first side conveyor line 7 is manually moved to the rectangular groove, so that a sliding edge 61 slides relative to the first inner wall 91 under the guidance of the first inner wall 91, respectively guiding the two rows of products to move into and out of the field of view of the electron microscope 8. After inspection, the tray 6 is transported to the main conveyor line 2 from the end of the second side conveyor line 4.

[0069] Specifically, tray 6 is also rectangular, such as... Figure 2 , Figure 3 As shown, the X direction is the second direction and the Y direction is the first direction. When the tray 6 is placed in the rectangular groove, it can move within the rectangular groove. At the same time, the limiting edge 62 corresponds to the second inner wall 92 and the sliding edge 61 corresponds to the first inner wall 91.

[0070] The electron microscope 8 on the workbench 9 is fixed in place. The length direction of the first inner wall 91 is consistent with the conveying direction of the main conveyor line 2. When the first row of products is inspected, the guide tray 6 of the first inner wall 91 away from the operator slides, so that the electron microscope 8 is aligned with each product for inspection in turn. Then, after moving the tray 6 along the Y direction, the guide tray 6 of the first inner wall 91 close to the operator slides, so that the electron microscope 8 is aligned with each product for inspection in turn, and thus the inspection of another row of products is completed. The unqualified products are placed in the storage box 95 on the workbench 9.

[0071] The rectangular groove assists in manually moving the tray 6, allowing operators to observe the test results on the monitor 1 while moving the tray, thus improving operational efficiency.

[0072] Since the workbench 9 is equipped with a first side conveyor line 7 and a second side conveyor line 4 that connect to the main conveyor line 2 on the left and right sides respectively, the microscopic inspection operator sits in front of the workbench 9, moves the tray 6 from the first side conveyor line 7 to the rectangular groove, and moves the tray 6 from the rectangular groove to the end of the second conveyor line, which facilitates the flow of the tray 6 into and out of the manual microscopic inspection station and shortens the handling time.

[0073] By setting up a manual microscopic inspection station on one side of the main conveyor line 2 of the conveyor tray 6, and extending a first side conveyor line 7 and a second side conveyor line 4 on the side of the main conveyor line 2 to receive the tray 6 that needs to be inspected and to move the tray 6 that has been inspected to the main conveyor line 2, the handling time of manual microscopic inspection is shortened. By setting a rectangular groove on the worktable 9 to guide the movement of the tray 6, the manual operator can accurately move the product to the field of view of the electron microscope 8, thereby improving the efficiency and accuracy of manual microscopic inspection.

[0074] In this embodiment, as Figure 3 As shown, the two second inner walls 92 are used to limit the travel of the tray 6 along the length of the first inner wall 91. When the tray 6 is at both ends of the travel, the second inner walls 92 limit the limiting edge 62, so that the head of the product in a row is in the field of view of the electron microscope 8.

[0075] Specifically, the product at the head of a row of products is located in the field of view of the electron microscope 8, and the field of view of the electron microscope 8 needs to be able to completely cover the product at the head during the movement of the tray 6.

[0076] The electron microscope 8 moves relative to the product by guiding a row of products through the first inner wall 91 within the rectangular groove. The second inner wall 92 limits the movement of the tray 6 at both ends, positioning the head of each row of products. This facilitates rapid switching and positioning between the two rows of products, improving the efficiency of manual microscopic examination.

[0077] Furthermore, such as Figure 2 , Figure 3 As shown, the limiting edges 62 set opposite to each other are parallel to each other and perpendicular to the sliding edge 61. One limiting edge 62 contacts the second inner wall 92 and slides relative to it, which is used to guide the movement of the tray 6 so that the field of view of the electron microscope 8 can switch between the two rows of products.

[0078] In this embodiment, the bottom wall 93 is a plane with a surface roughness of less than or equal to Ra 1.6μm, making the bottom wall 93 sufficiently smooth.

[0079] Example 2:

[0080] like Figures 1-5 As shown, the manual microscopic examination production line of this embodiment further includes a slide 94 based on embodiment one. The slide 94 includes a plate-shaped body 941, which is rectangular. The edge of the plate-shaped body 941 is provided with multiple notches 942. A buffer plate 943 is installed on the edge of the plate-shaped body 941 at a position avoiding the notches 942. The upper edge of the buffer plate 943 is higher than the upper surface of the plate-shaped body 941 and forms a limiting groove for the tray 6 with the upper surface of the plate-shaped body 941. When the tray 6 is placed in the limiting groove, the notches 942 are located below the tray 6. The lower surface of the plate-shaped body 941 slides in cooperation with the bottom wall 93. The sliding edge 61 and the limiting edge 62 are indirectly in contact with the rectangular groove through the buffer plate 943.

[0081] Specifically, the plate-shaped body 941 is a thick aluminum plate, which ensures rigidity while reducing the weight of the slide 94; the buffer plate 943 is made of plastic, specifically POM; when the sliding edge 61 slides under the guidance of the first inner wall 91, the sliding edge 61 indirectly contacts and is guided by the first inner wall 91 through the buffer plate 943; when the second inner wall 92 guides the pallet 6 to move, the limiting edge 62 indirectly contacts and is guided by the second inner wall 92 through the buffer plate 943.

[0082] A slide block 94 is slidably set in the rectangular groove. A notch 942 is provided on the slide block 94 to facilitate the support and placement of the tray 6. The smoothness of the sliding of the tray 6 on the bottom wall 93 can be adjusted by changing the sliding engagement method between one slide block 94 and the bottom wall 93. This eliminates the need to impose higher requirements on each tray 6 and reduces wear on the bottom wall 93. A buffer plate 943 is provided on the slide block 94 to place and position the tray 6 while preventing excessive impact between the sliding tray 6 and the rectangular groove, which could cause vibration and change the position of the product 6 on the tray 6.

[0083] Furthermore, such as Figure 5 As shown, multiple omnidirectional balls 944 are installed on the lower surface of the plate-shaped body 941. The multiple omnidirectional balls 944 slide in engagement with the bottom wall 93 to provide sliding support for the plate-shaped body 941. The omnidirectional balls 944 improve the smoothness of the sliding of the entire tray 6 relative to the bottom wall 93 and reduce the workload of the operator.

[0084] Example 3:

[0085] The manual microscopic examination production line in this embodiment is based on the above embodiments, such as... Figure 2 , Figure 7 , Figure 8 As shown, the conveying directions of the first side conveyor line 7 and the second side conveyor line 4 are perpendicular to the conveying direction of the main conveyor line 2. A reversing mechanism 3 is provided at the main conveyor line 2 corresponding to the first side conveyor line 7 and the second side conveyor line 4. A first blocking mechanism for blocking the pallet 6 is provided on the main conveyor line 2 downstream of the reversing mechanism 3, so that the pallet 6 is located directly above the reversing mechanism 3.

[0086] The reversing mechanism 3 includes a first mounting frame 34 fixedly installed on the frame of the main conveyor line 2, and a first bracket 33 slidably installed on the first mounting frame 34 in a vertical direction. A first cylinder 35 for driving the first bracket 33 to rise and fall is fixedly installed on the first mounting frame 34. A first motor 32 is fixedly installed on the first bracket 33. A horizontal conveyor belt 31 is rotatably installed on the first bracket 33. The first motor 32 is connected to the horizontal conveyor belt 31 in a transmission connection. The conveying direction of the horizontal conveyor belt 31 is perpendicular to the conveying direction of the main conveyor line 2.

[0087] When the first cylinder 35 drives the first bracket 33 to descend, the conveying surface of the horizontal conveyor belt 31 is lower than the conveying surface of the main conveyor line 2. When the first cylinder 35 drives the first bracket 33 to rise, the conveying surfaces of the first side conveyor line 7 and the second side conveyor line 4 are flush with the conveying surface of the horizontal conveyor belt 31 and higher than the conveying surface of the main conveyor line 2.

[0088] In another embodiment, such as Figure 6 As shown, multiple workbenches 9 are spaced apart along the conveying direction of the main conveyor line 2.

[0089] Specifically, the workbench 9 can be located on the same side of the main conveyor line 2 or on different sides. Each workbench 9 is equipped with a first side conveyor line 7 and a second side conveyor line 4. When the production cycle of the product is fast, the output of manual microscopic inspection is increased to match the output of the product and ensure the quality of product inspection.

[0090] Furthermore, such as Figures 9-11 As shown, the first side conveyor line 7 is provided with a buffering mechanism 5 for buffering multiple trays 6 along the vertical direction, and a second blocking mechanism located on the first side conveyor line 7 downstream of the buffering mechanism 5. The second blocking mechanism is used to block the trays 6 so that the trays 6 are located in the buffering mechanism 5.

[0091] The buffer mechanism 5 includes a second mounting frame 54 fixedly installed on the frame of the first side conveyor line 7. A second motor 55 is fixedly installed on the second mounting frame 54. A second bracket 53 for lifting the tray 6 is slidably installed on the second mounting frame 54 along the vertical direction. The second motor 55 is connected to the second bracket 53 for driving the second bracket 53 to lift and lower, thereby driving the tray 6 to lift and lower.

[0092] It also includes a pair of second cylinders 52 fixedly installed on both sides of the first side conveyor line 7. The moving end of the second cylinder 52 is equipped with a pallet 521. The second cylinder 52 is used to drive the pallet 521 to extend and retract in the horizontal direction, intermittently supporting the pallet 6, so that the supported pallet 6 is located above the conveying surface of the first side conveyor line 7, and avoids the pallet 6 located on the first side conveyor line 7.

[0093] When the cycle time of the tray 6 delivered by the first side conveyor line 7 matches the cycle time of the microscopic inspection, the buffer mechanism 5 does not work.

[0094] When a tray 6 at the end of the first side conveyor line 7 has not been removed, or when microscopic inspection cannot be performed temporarily, the buffer mechanism 5 is activated, the second blocking mechanism blocks the tray 6 of the autonomous conveyor line 2, and the second bracket 53 rises under the drive of the second motor 55. When the tray 6 is higher than the pallet 521, the second cylinder 52 drives the pallet 521 to extend. At this time, the second motor 55 drives the second bracket 53 to descend, so that the tray 6 falls on the pallet 521.

[0095] When another pallet 6 needs to be buffered, the pallet 6 is conveyed by the first side conveyor line 7 to the area directly below the previous pallet 6 and then blocked by the second blocking mechanism. The second bracket 53 rises under the drive of the second motor 55. When the pallet 6 contacts the pallet 6 above it, the second bracket 53 supports all the pallets 6. At this time, the pallet plate 521 retracts under the drive of the second cylinder 52. The second motor 55 continues to drive the second bracket 53 to rise, so that the bottom pallet 6 is above the pallet plate 521. At this time, the second cylinder 52 drives the pallet plate 521 to extend, and then the second motor 55 drives the second bracket 53 to descend, so that the bottom pallet 6 falls on the pallet plate 521.

[0096] When the buffered trays 6 need to be placed back onto the first side conveyor line 7 in sequence, the buffer mechanism 5 operates in the opposite manner to the above process, so that the second to last tray 6 is supported by the pallet 521, and the bottom tray 6 is separated from the second to last tray 6 and placed on the first side conveyor line 7, and then conveyed to the end of the first side conveyor line 7.

[0097] Specifically, the upper surface of the pallet 6 is provided with multiple positioning pins 63, and the lower surface of the pallet 6 is provided with multiple positioning holes corresponding to the positioning pins 63. When the pallets 6 are stacked, the positioning pins 63 are inserted into the positioning holes of the upper pallet 6 to ensure the overlap of the pallets 6. The pallet 6 is provided with three through holes 64, which are arranged in a triangle. The upper surface of the second bracket 53 is provided with three pins 531 corresponding to the through holes 64. The pins 531 cooperate with the through holes 64 to achieve positioning when the second bracket 53 lifts the pallet 6, ensuring good correspondence between the positioning pins 63 and the positioning holes of the upper pallet 6. In addition, when the pallet 6 is transferred from the first side conveyor line 7 to the worktable 9, the positioning pins 63 can be grasped.

[0098] A buffer mechanism 5 is set on the first side conveyor line 7 to buffer multiple trays 6 vertically, which improves the flexibility of the manual microscopic inspection conveyor line. At the same time, when a main conveyor line 2 is matched with multiple worktables 9, it is convenient to adjust the workload between multiple worktables 9, so that the inspection efficiency matches the output of the products.

[0099] The first side conveyor line 7 corresponding to the buffer mechanism 5 is provided with multiple vertical guide structures 51, which form guide grooves on the edge of the corresponding tray 6. A sensor group 511 for detecting the number of trays 6 is installed on the guide structure 51.

[0100] When there are a large number of stacked trays 6, the guide structure 51 guides and protects the trays 6 from the outside. At the same time, the sensor group 511 detects whether there are trays 6 on the buffer mechanism 5 and whether the number of trays 6 has reached or is close to the limit of the buffer quantity, so as to ensure the safety of the buffer mechanism 5 and report the current material storage status of the microscopic inspection station to the manual microscopic inspection production line.

[0101] Specifically, the sensor group 511 can be multiple proximity switches arranged along the height direction of the guide structure 51. There are four guide structures 51, and each guide structure 51 is a right-angled bent structure.

[0102] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
