Description

Technical Field

[0001] The present application relates to the field of integrated circuit packaging, and in particular to a transmission device for pin shaping. Background Art

[0002] Integrated circuit packaging refers to the process of electrically connecting the circuits in the chip to the pins of the package shell through wires. These pins are then soldered to the solder joints on the printed circuit board (PCB). The wires in the PCB are then used to electrically connect the chip to external circuits including other devices, thereby achieving electrical connection between the chip and the external circuits.

[0003] The quality of the aforementioned integrated circuit packaging directly affects the performance of the chip itself, and at the same time, it also affects the design and manufacturing process of the PCB connected to it. This shows that the quality of the integrated circuit packaging is of vital importance.

[0004] During the production process, due to the influence of external forces, the metal pins on the outer shell of the packaged product (such as the Small Out-Line Package, SOP) may become warped, skewed, or have other poor morphology. When soldering the aforementioned products with poor morphology to the PCB board, unstable phenomena such as desoldering, solder leaks, and false connections may occur, affecting product quality and reliability.

[0005] Therefore, it is necessary to reshape the pins on the packaged product shell, and optionally to inspect the reshaped pins. During the pin shaping and inspection process, the packaged product needs to be transferred to the inspection device or the inspection device through a transmission device. In this process, the packaged product needs to be placed in the tooling of the transmission device first, or the shaped / inspected packaged product needs to be taken out of the tooling. In this process, the packaged product may not be placed correctly in the tooling, the package shell may not be fully embedded in the tooling, resulting in subsequent shaping / inspection failure, or the shaped / inspected packaged product cannot be successfully removed from the tooling, resulting in subsequent loading failure. The above problems restrict the development of the packaged product inspection / inspection process towards a more automated direction. Utility Model Content

[0006] To solve the above problems in the prior art, the present invention provides a transmission device for pin shaping, which includes a carrier plate, multiple tooling and a detection device, wherein the detection device includes a column, a light source, an optical waveguide, a sensor and one or more cantilevers; wherein,

[0007] The carrier plate can rotate step by step, and a through hole is provided at the center of rotation;

[0008] A plurality of toolings are evenly distributed on the upper surface of the carrier plate for placing target products;

[0009] The column passes through the through hole;

[0010] One or more cantilevers are arranged above the carrier plate, the proximal ends of the cantilevers are connected to the columns, and the distal ends of the cantilevers extend to the inner sides of the plurality of toolings;

[0011] The incident end of the optical waveguide is connected to the light source, and the output end is arranged at the far end of the cantilever;

[0012] The sensor is arranged outside the plurality of toolings and opposite to the emission end;

[0013] Based on the step-by-step rotation of the carrier plate, multiple toolings can pass between the output end and the corresponding sensor one by one, so as to detect the status of the target products placed in the multiple toolings one by one.

[0014] In the above technical solution, the carrier plate moves in a step-by-step manner, driving multiple toolings to pass between the output end and the sensor one by one, and the placement status of the packaged products in each tooling can be obtained through the feedback signal of the sensor.

[0015] In this solution, through the cantilever and column structure, optical waveguides, light sources and other related devices used to provide detection light can be concentrated in the middle position of the device. Multiple tooling surrounds optical waveguides, light sources and other devices. The overall structure is compact, and there is sufficient space outside the multiple tooling. Various handling devices, detection devices or packaging disposal devices can be arranged according to local conditions. It has strong versatility and scalability.

[0016] Optionally, the tooling includes a groove for placing one or more target products.

[0017] Furthermore, the supporting plate is circular, and the through hole and the column are arranged at the center of the supporting plate; one or more cantilevers and grooves extend along the radial direction of the supporting plate.

[0018] The emission direction of the emission end is the radial direction of the carrier plate.

[0019] The aforementioned optional solution allows the outgoing light from the exit end to be emitted toward the sensor along the groove of the tooling, and can detect packaged products placed in or along the groove. Furthermore, multiple packaged products can be placed in the groove, and the outgoing light from the exit end can detect multiple packaged products at the same time.

[0020] Optionally, the carrier plate has multiple evenly distributed weight-reducing holes. This design can reduce the carrier plate's moment of inertia, indirectly improving the carrier plate's positioning accuracy. It also allows for a smaller carrier plate drive device, saving space for installation of light sources and other detection-related equipment.

[0021] Optionally, the cantilever also includes:

[0022] The fixing plate is connected to the distal end of the cantilever. The fixing plate includes a plurality of fixing holes with different heights. The output end of the optical waveguide is installed in one of the plurality of fixing holes.

[0023] In the above solution, the fixing plate is used to fix the output end of the optical waveguide and determine the output direction of the light at the output end. In addition, the fixing plate can also block stray light from entering the sensor to avoid interference.

[0024] The multiple fixing holes have different heights, and the light emission height of the emission end installed therein can be adjusted thereby.

[0025] In another alternative, the fixing plate includes a fixing hole and an adjustment hole. The optical waveguide's output end is mounted in the fixing hole. The adjustment hole is a long, rectangular hole used to adjust the height of the fixing plate. This solution adjusts the overall height of the fixing plate to adjust the light output height of the output end mounted thereon.

[0026] Optionally, the cantilever specifically includes a first cantilever and a second cantilever; wherein,

[0027] The emitting end of the light waveguide provided on the first cantilever is higher than the top of the tube shell of the target product correctly placed in the groove, and lower than the height of the tube shell of the target product superimposed on the top surface of the tooling;

[0028] The height of the light waveguide emitting end arranged on the second cantilever is between the top and the bottom of the tube shell of the target product which is correctly placed in the groove.

[0029] In the aforementioned optional solution, the optical waveguide of the first cantilever is used to detect whether the packaged product is correctly placed in the tooling. When the packaged product is not completely placed, its top is higher than when it is correctly placed, causing the light emitted by the optical waveguide of the first cantilever to be blocked. At this time, the sensor corresponding to the optical waveguide of the first cantilever sends a feedback signal that no light is received, indicating that the packaged product is not completely placed.

[0030] In the aforementioned alternative, the optical waveguide of the second cantilever is used to detect whether the packaged product has been correctly removed from the tooling. If a packaged product is left in the groove, it blocks the light emitted by the optical waveguide of the second cantilever. At this point, the sensor corresponding to the optical waveguide of the second cantilever emits a feedback signal indicating that the packaged product has not been removed and is missing from the tooling.

[0031] Optionally, there are 6 toolings; the angle between the first cantilever and the second cantilever is 120 degrees.

[0032] Optionally, it includes a plurality of operating positions arranged around the carrier plate;

[0033] Multiple operation bits include:

[0034] The loading operation position is arranged upstream of the first cantilever and downstream of the second cantilever based on the rotation direction of the carrier plate.

[0035] In the aforementioned optional solution, the first cantilever is used to detect whether the upstream loading operation position correctly places the packaged product in the tooling, thereby preventing the tooling with incorrectly placed packaged products from entering the subsequent shaping / inspection operation position.

[0036] Optionally, multiple operation bits include:

[0037] The unloading operation position is arranged downstream of the first cantilever and upstream of the second cantilever based on the rotation direction of the carrying plate.

[0038] In the aforementioned optional solution, the second cantilever is used to ensure that no packaged products are left in the tooling passing through it, and to detect whether the unloading operation station has correctly unloaded the product, thereby preventing the downstream loading operation station from repeatedly loading the product into the tooling. Using the transmission device for pin shaping provided in the embodiment of the present application, before shaping the pins, it is possible to detect whether the upstream loading operation station has correctly placed the packaged product in the tooling, and after inspecting the shaped pins, it can ensure that the unloading operation station has removed all packaged products from the tooling passing through it.

[0039] In summary, the transmission device for pin shaping, including a detection device, provided in the embodiments of this application, can detect the status of packaged products within the tooling before and after pin shaping, thereby at least avoiding the technical problem of shaping failures due to abnormal status of packaged products within the tooling. Furthermore, it lays the foundation for the development of more automated pin shaping and detection processes for packaged products. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] In this specification, it will also be understood that when a component is referred to as being relative to other components, such as being "connected to" other components, the component may be directly connected to or directly coupled to the other components, or there may be a third component in between; in addition, in the embodiments of the present application, "connection" may specifically be an electrical connection, a structural connection, or an optical connection.

[0057] The present application will now be described more fully below with reference to the accompanying drawings. However, the present application may be implemented in many different ways and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided herein to make the present application more detailed and complete and to fully convey the scope of the present application to those skilled in the art. Throughout the present application, the same reference numerals represent the same objects.

[0058] It should be understood that since the optical fiber in the embodiment of the present application is a flexible device and does not have a fixed shape, only its output end is shown in some drawings. As long as the connection description of its incident end is clear, it does not affect the clear description of the embodiment.

[0059] At least in order to solve the problems existing in the above-mentioned prior art, the embodiment of the present application provides a transmission device for pin shaping, which is as follows: Figure 1 or Figure 2As shown, it includes a carrier plate 100 and a plurality of tooling 200 , as well as a detection device. The aforementioned detection device specifically includes a column 300 and one or more cantilevers 400 .

[0060] The carrier plate 100 can rotate in a step-by-step manner, and a through hole 110 penetrating the carrier plate 100 is provided at the rotation center.

[0061] The plurality of tooling 200 is evenly distributed on the upper surface of the carrier plate 100 for placing the target product 000. Preferably, the plurality of tooling 200 is evenly distributed on the upper surface of the carrier plate 100 in a circular pattern.

[0062] The column 300 is disposed through the through hole 110 . Typically, the column 300 is a cylinder and is coaxially disposed with the rotation axis of the carrier plate 100 .

[0063] In one embodiment, the through hole 110 is a circular hole, and the rotation axes of the through hole 110 , the pillar 300 , and the carrier plate 100 are coaxially arranged.

[0064] like Figure 1 or Figure 2 As shown, one or more cantilevers 400 are disposed above the carrier plate 100 , the proximal end 410 of the cantilever 400 is connected to the column 300 , and the distal end 420 of the cantilever 400 extends to the inner side of the plurality of tooling 200 .

[0065] It should be understood that, unless otherwise specified, the “proximal end” described in the embodiments refers to the end of the component close to the center of the carrier plate 100 , while the “distal end” refers to the end of the component close to the edge of the carrier plate 100 .

[0066] In a typical embodiment, the cantilever 400 is disposed parallel to the upper surface of the carrier plate 100 .

[0067] The detection device further includes a light source and an optical waveguide 500 . The incident end of the optical waveguide 500 is connected to the light source, and the output end 510 is disposed at the distal end 420 of the cantilever 400 .

[0068] In a preferred embodiment, the optical waveguide 500 is specifically an optical fiber, but the present application is not limited thereto. The optical waveguide 500 can be any device or structure that can form an optical path between the light source and the cantilever distal end 420, such as a mirror assembly including a reflector / refractor.

[0069] In a preferred embodiment, the light source is a laser, which is arranged below the carrier plate 100. The column 300 is a hollow column. The optical fiber is arranged along the cantilever 400 and passes through the hollow part of the column 300, extending to the bottom of the carrier plate 100 to connect with the light source.

[0070] The detection device further includes a sensor, which is disposed outside the plurality of fixtures 200 and opposite to the emission end 510;

[0071] In a typical embodiment, Figure 1 As shown, the transmission device is centered on the column 300, and from the inside to the outside, it is: the column 300, the through hole 110, the cantilever 400, the surrounding multiple tooling 200 and the sensor (not shown in the figure).

[0072] Based on the step-by-step rotation of the carrier plate 100 , the plurality of toolings 200 can pass between the emission end 510 and the sensor one by one.

[0073] In the above embodiment, the carrier plate 100 moves in a step-by-step manner, driving multiple tooling 200 to pass between the output end 510 and the sensor in the detection device one by one, and the placement status of the target product 000 (packaged product) in each tooling 200 can be obtained through the feedback signal of the sensor.

[0074] In the embodiment of the present application, the placement of the target product 000 detected by the detection device specifically includes: whether the target product 000 is present in the tooling 200, whether the position of the target product 000 placed in the tooling 200 is correct, etc.

[0075] In the embodiment, through the structural form of the cantilever 400 and the column 300, the optical waveguide 500, the light source and other related devices for providing detection light can be concentratedly arranged in the middle position of the transmission device. Multiple tooling 200 surround the optical waveguide 500, the light source and other devices. The overall structure is compact, and sufficient space is left on the outer periphery of the multiple tooling 200. Various handling devices, detection devices or packaging pin shaping devices can be arranged according to local conditions to transfer the target product between the various devices and at the same time detect its placement in the tooling. It has strong versatility and scalability.

[0076] Furthermore, considering that existing devices for inspecting or shaping the pins on packaged product housings are more suitable for whole sheets of products that have not been cut and arranged in an array, there are no dedicated devices or methods in the prior art for already cut products. It was also discovered that during the process of shaping and inspecting the pins of cut products, the cut products need to be frequently removed from and placed on the tooling, which makes it more likely that unsuccessful unloading will lead to repeated loading, as well as incorrect placement of loaded materials on the tooling. This not only hinders the automation of the inspection and handling process, but also causes new pin deformation.

[0077] The detection device in the aforementioned embodiment is suitable for singulated packaged products. Through pre-detection, various problems caused by frequent removal and placement of the aforementioned single products from the tooling can be avoided.

[0078] In addition, the arrangement of the aforementioned pillar 300, cantilever 400 and optical waveguide 500 eliminates the need for the optical device to rotate along with the carrier plate 100, thereby avoiding twisting of the optical fiber, and the movement of the carrier plate 100 does not affect the optical path of the detection light.

[0079] In an embodiment, Figure 4 As shown, the tool 200 includes a groove 210, and the groove 210 is used to place one or more target products 000. Figure 4 As shown, the package of the target product 000 is located in the groove 210 , and the pins of the target product 000 are carried on the surfaces of the tool 200 located on both sides of the groove 210 .

[0080] Correspondingly, Figure 2 As shown, the carrier plate 100 is circular, the through hole 110 and the column 300 are arranged at the center of the carrier plate 100, one or more cantilevers 400 and grooves 210 extend along the radial direction of the carrier plate 100; and the output end 510 is configured to emit light along the radial direction of the carrier plate 100.

[0081] The above-mentioned embodiment enables the outgoing light from the exit end 510 to be emitted toward the sensor along the groove 210 of the tooling 200, so that the target product 000 placed in the groove 210 or along the groove 210 can be detected. Furthermore, multiple target products 000 can be placed in the groove 210, and the outgoing light from the exit end 510 can detect multiple target products 000 at the same time.

[0082] In a typical embodiment, Figure 4 The groove 210 is shown with adjustable stoppers at both ends to limit the position or number of target products 000 placed within the groove 210. As can be seen from the figure, the top of the stopper is also provided with a groove to allow the light emitted from the output end 510 to pass through the stopper, thereby preventing the stopper from affecting the detection.

[0083] like Figure 2 As shown, in a preferred embodiment, the carrier plate 100 has a plurality of evenly distributed weight-reducing holes 120. This embodiment can reduce the carrier plate's moment of inertia, indirectly improving the carrier plate's positioning accuracy. At the same time, a smaller carrier plate drive device can be used, and the saved space can be used to install detection-related equipment such as a light source.

[0084] Typical, such as Figure 2 As shown, the weight-reducing holes 120 are trapezoidal or fan-shaped and are evenly distributed around the circumference of the carrier plate 100 . The number of the holes 120 can be an even number such as four or six.

[0085] In an embodiment, the carrier plate driving device may be a servo motor, which is disposed below the carrier plate 100 , and a driving end thereof is connected to the through hole 110 .

[0086] In a typical embodiment, Figure 5 As shown, the cantilever 400 further includes a fixing plate 430 connected to the cantilever distal end 420 . The fixing plate 430 includes a plurality of fixing holes 431 of different heights. The output end 510 of the optical waveguide 500 can be optionally installed in one of the plurality of fixing holes 431 .

[0087] Preferably, the fixing plate 430 is rectangular and perpendicular to the upper surface of the carrier plate 100 .

[0088] Preferably, the fixing plate 430 is perpendicular to the radial direction of the carrying plate 100 .

[0089] The light emitted from the output end 510 of the optical waveguide 500 is perpendicular to the fixing plate 430 where the light is located.

[0090] The fixing plate 430 is used to fix the output end 510 of the optical waveguide and determine the output direction of the light from the output end 510. In addition, the fixing plate 430 can also block stray light from entering the sensor to avoid interference.

[0091] The multiple fixing holes have different heights, and the light emission height of the emission end installed therein can be adjusted thereby.

[0092] In another typical embodiment, the fixing plate 430 includes an adjustment hole 432, which is an elongated hole extending in the longitudinal direction of the fixing plate 430 and is used to adjust the height of the fixing plate 430 relative to the carrier plate 100. A screw is passed through the adjustment hole 432 to connect the cantilever 400. After the height of the fixing plate 430 is adjusted, the screw is tightened to secure the fixing plate 430.

[0093] In the aforementioned embodiment, the overall height of the fixing plate 432 is adjusted to thereby adjust the light emission height of the emission end 510 mounted thereon.

[0094] Compared with the embodiment in which the fixing plate 432 only includes a plurality of fixing holes, the adjustment hole 432 can linearly adjust the height of the emission end 510 and has better versatility.

[0095] In a typical embodiment, a plurality of fixing holes 431 and adjustment holes 432 may be provided on the fixing plate 432 at the same time.

[0096] In a typical embodiment, there are two adjustment holes 432 symmetrically disposed on both sides of the emission end 510 .

[0097] like Figure 2 As shown, in a typical embodiment, the cantilever includes a first cantilever 401 and a second cantilever 402 , and the whole is in the form of a clock hand.

[0098] By adopting an embodiment such as the aforementioned adjustment hole 432 and / or multiple fixing holes 431, the light waveguide emitting end provided on the first cantilever 401 is slightly higher than the top of the tube shell of the target product 000 correctly placed in the groove 210. Specifically, the height of the light waveguide emitting end provided on the first cantilever 401 is lower than the height of the tooling top surface superimposed on the tube shell of the target product.

[0099] At the same time, the height of the light waveguide emitting end disposed on the second cantilever 402 is between the top and bottom of the tube package of the target product 000 correctly placed in the groove 210. In the embodiment where a blocking block is disposed in the groove 210, to ensure that light can be received by the corresponding sensor, the height of the light waveguide emitting end disposed on the first cantilever 401 and the second cantilever 402 must be higher than the bottom of the groove at the top of the blocking block.

[0100] In the aforementioned embodiment, the optical waveguide of the first cantilever 401 is used to detect whether the target product 000 is correctly placed in the tooling 200. When the tube shell of the target product 000 is not correctly placed in the groove 210, its top will be higher than when it is correctly placed, causing the light emitted by the optical waveguide of the first cantilever 401 to be blocked. At this time, the sensor corresponding to the optical waveguide of the first cantilever 401 sends a feedback signal that no light is received, indicating that the target product 000 is not completely placed.

[0101] The optical waveguide of the second cantilever 402 is used to detect whether the target product 000 is completely removed from the tooling 200. When the target product 000 is left in the groove 210, the target product 000 blocks the light emitted by the optical waveguide of the second cantilever 402. At this time, the sensor corresponding to the optical waveguide of the second cantilever 402 sends a feedback signal indicating that the target product 000 has not been removed and is missing from the tooling 200.

[0102] In one embodiment, the sensor is connected to an indicator light, a buzzer, or a control module.

[0103] In a typical embodiment, there are six toolings 200; the angle between the first cantilever 401 and the second cantilever 402 is 120 degrees. Figure 2 As shown, the two cantilevers point to the three o'clock and eleven o'clock directions respectively.

[0104] like Figure 6 As shown, in a typical embodiment, a plurality of operating positions are arranged around the carrier plate 100; the plurality of operating positions include:

[0105] The loading operation position 610 is located upstream of the first cantilever 401 and downstream of the second cantilever 402 based on the rotation direction of the carrier plate 100. Typically, it is located within the angle between the first cantilever 401 and the second cantilever 402, such as Figure 2 One o'clock direction is shown.

[0106] The first cantilever 401 and the optical waveguide thereon, as well as the corresponding sensor, are used to detect whether the upstream loading operation position 610 correctly places the target product 000 in the tooling 200, so as to prevent the tooling with the target product 000 incorrectly placed from entering the subsequent shaping / detection operation position.

[0107] Multiple operation bits also include:

[0108] The unloading operation position 620 is located downstream of the first cantilever 401 and upstream of the second cantilever 402 based on the rotation direction of the carrier plate 100. Figure 2 The five o'clock position is shown.

[0109] The second cantilever 402 and the optical waveguide thereon, as well as the corresponding sensor, are used to ensure that there is no target product 000 left in the tooling 200 passing through it, detect whether the unloading operation position 620 is unloading correctly, and avoid repeated loading of materials to the tooling by the downstream loading operation position.

[0110] In a preferred embodiment, if Figure 2 As shown, other operating positions can be set at the nine o'clock direction and the seven o'clock direction in the figure, for example, a shaping operating position is set downstream of the first cantilever 401 at the nine o'clock direction, or a detection operating position is set at the seven o'clock direction.

[0111] In the aforementioned embodiments, each operating position can be manually operated, or more preferably, an automated loading and handling device, unloading and handling device, shaping device and / or detection device can be set to realize the automated shaping and detection process of the packaged products.

[0112] In summary, the transmission device for pin shaping provided in the embodiment of the present application can be used to perform pre-inspection of the target product in the tooling during the transmission of the target product before and after shaping / inspection. For example, before shaping the pins, it can be detected whether the packaged product is correctly placed in the tooling, at least avoiding the problem of shaping failure. In addition, after the shaped pins are inspected, it can be ensured that all packaged products are removed from the tooling, at least avoiding the problem of subsequent loading failure. In addition, the transmission device of the embodiment of the present application lays the foundation for the development of the shaping / inspection process of packaged products in a more automated direction.

[0113] The above descriptions are only some specific embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the embodiments of the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
