[0022] In this embodiment, the material of the buffer member can be rubber or thermoplastic elastomer.

[0023] In some embodiments, a transition round corner or a transition inclined surface is arranged between the bottom and the wall of the adsorption groove.

[0024] In the technical solution, the transition fillet or transition slope is arranged between the groove bottom and the groove wall of the adsorption groove, effectively reducing the local stress and friction when the packaging workpiece contacts the groove wall, improving the smoothness of the packaging workpiece placement and the self-positioning capability, significantly reducing the scratching and pin damage risk caused by operation errors, improving the stability of the packaging workpiece bearing and the fault tolerance of the sorting equipment, and being particularly suitable for low-precision positioning environment, ensuring production efficiency and yield.

The relative position of the workbench and the assembly groove is limited by the cooperation of the two, ensuring the stable installation and repeated positioning of the workbench, preventing the workbench from being displaced under vibration or mechanical impact, and ensuring the accurate bearing and adsorption of the packaging workpiece on the buffer member. Combined with the elastic buffer and adsorption groove design of the buffer member, the reliability and packaging workpiece protection capability of the equipment in a low-precision positioning environment are significantly improved, thereby improving the yield and production efficiency.

[0031] In some technical solutions, optionally, a bonding layer is arranged between the assembly groove and the buffer, and the bonding layer is arranged on the side surface of the assembly groove facing the buffer and / or the side surface of the buffer facing the assembly groove.

[0032] In the present solution, the bonding layer is arranged between the assembly groove and the buffer, the buffer is fixed by bonding, and the stability and positioning accuracy of the buffer in the assembly groove are improved. The bonding layer not only prevents the buffer from sliding due to vibration or mechanical impact, but also compensates for the assembly gap, enhances the sealing and flatness of the overall structure.

[0035] Since the packaging workpiece sorting assembly comprises a packaging workpiece sorting jig, it has the beneficial effects of any of the packaging workpiece sorting jigs, which will not be described here.

[0036] In some technical solutions, at least part of the packaging workpiece body is arranged in the adsorption groove, and the length of the pin is less than the groove depth of the adsorption groove.

[0059] In order to enable a more complete understanding of the above-mentioned purposes, features and advantages of the embodiments of the present application, the embodiments of the present application are further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0060] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, embodiments of the present application can be practiced without the specific details, which are not described herein. In other instances, well-known methods, procedures and components have not been described in detail so as not to obscure the present application.

[0061] In the sorting stage after packaging, integrated cutting and sorting machines typically require placing the packaged workpieces into positioning grooves on a worktable for appearance inspection, performance testing, or automated handling. The worktables in related technologies are often made entirely of metal, with the grooves machined directly onto the metal surface.

[0062] The existing structure has the following shortcomings:

[0063] The metal groove has high hardness and sharp edges. When the packaged workpiece undergoes slight displacement or during placement / removal, the pins or sides of the packaged workpiece are prone to contact with the groove edge, causing scratches, plating peeling, or pin bending.

[0064] When a metal platform is placed with the leads of a packaged workpiece facing downwards, static electricity can easily be generated due to friction or contact, causing damage to the internal circuitry of the packaged workpiece.

[0065] Metal surfaces have poor sealing properties, and when used with vacuum adsorption or negative pressure systems, the adsorption force of the through holes at the bottom of the groove is limited, which is not conducive to the stable clamping and packaging of workpieces.

[0066] Metal tabletops have poor vibration absorption properties, and impacts from robotic arms or feeding mechanisms can easily cause micro-movements in the packaged workpieces, increasing the risk of scratches. At the same time, they require high positioning accuracy in the vertical direction, reducing versatility.

[0067] The following reference Figures 1 to 14 Some embodiments of the present invention are described.

[0068] like Figure 1 , Figure 3 and Figure 4 As shown, this embodiment provides a packaging workpiece sorting fixture 1, such as... Figure 10 As shown, a loading groove 111 is provided on one side of the workbench 11, and a buffer 12 is embedded in the loading groove 111. The elastic modulus of the buffer 12 is less than that of the workbench 11. The surface of the buffer 12 is provided with multiple adsorption grooves 121 to accommodate the packaged workpieces to be sorted, forming a flexible support platform that combines rigidity and flexibility. This structure effectively absorbs and buffers the mechanical impact and positional deviation of the packaged workpieces in environments with low operating precision, significantly reduces the scraping between the packaged workpieces and the hard metal table surface, avoids the bending of the packaged workpiece pins and the peeling off of the plating, and improves the yield of packaged workpieces. At the same time, the flexible support of the buffer 12 and the fault-tolerant positioning function of the adsorption grooves 121 reduce the equipment's dependence on the positioning accuracy in the vertical and horizontal directions, improve the fault tolerance and adaptability of the equipment, and optimize production efficiency.

[0069] Specifically, the packaging workpiece sorting fixture 1 comprises a workbench 11 and a buffer 12, wherein the workbench 11 is the main load-bearing component of the packaging workpiece sorting device, and has a relatively large elastic modulus to ensure the rigidity and stability of the overall structure.

[0070] Optionally, a loading groove 111 is formed on one side of the workbench 11 for mounting the buffer 12.

[0071] The workbench 11 with high rigidity ensures the stability of the overall structure of the device, and avoids further deterioration of the positioning accuracy of the packaging workpiece due to deformation.

[0072] The loading groove 111 is a space structure formed on the side of the workbench 11 away from the base structure 15, and is used for embedding the buffer 12. The loading groove 111 is closely matched with the buffer 12 to ensure stable installation of the buffer 12. The loading groove 111 is located on one side of the workbench 11 to form an installation space and a positioning reference for the buffer 12.

[0073] The loading groove 111 provides an accurate installation position for the buffer 12 to prevent displacement of the buffer 12 due to vibration or mechanical impact. The buffer 12 is separated from the rigid workbench 11 by physical isolation to prevent direct contact between the packaging workpiece and the metal table top.

[0074] Optionally, the size and depth of the loading groove 111 are designed to take into account the elastic performance of the buffer 12 and the compactness of the overall structure.

[0075] The buffer 12 is placed in the loading groove 111, and the elastic modulus of the buffer 12 is smaller than that of the workbench 11, so the buffer 12 has good elastic buffering performance. The buffer 12 is mechanically matched with the loading groove 111. The elastic buffer 12 effectively absorbs the impact force during placement and handling of the packaging workpiece, relieves the vertical impact caused by low operation accuracy, and reduces direct contact between the pins of the packaging workpiece and the hard metal table top, thereby avoiding pin scratching and plating peeling. The elastic structure of the buffer 12 allows the packaging workpiece to have a certain range of horizontal and vertical deviation, thereby achieving fault-tolerant positioning. Under the action of the buffer 12, the placement accuracy requirements of the device on the mechanical arm or the operator can be reduced, and the universality and production efficiency of the device can be improved.

[0076] Optionally, the buffer 12 and the workbench 11 are fixed by positioning pins or buckles.

[0077] Optionally, the buffer 12 is completely embedded in the loading groove 111, and the surface of the buffer 12 is flush or slightly lower than the surface of the workbench 11.

[0078] Of course, the surface of the buffer 12 is provided with a plurality of adsorption grooves 121 for accommodating the packaging workpieces to be sorted. The adsorption grooves 121 are recessed structures provided on the buffer 12, and do not require additional fixing devices.

[0079] Optionally, the adsorption grooves 121 are uniformly distributed on the surface of the buffer 12 to ensure the stability of the batch placement of the packaging workpieces.

[0080] It can be understood that the adsorption grooves 121 provide positioning space for the packaging workpieces, limit the movement of the packaging workpieces in the X direction or the Y direction on the machining table, and reduce side scratches. Under the action of the elastic cooperation between the adsorption grooves 121 and the buffer 12, the flexibility of the packaging workpieces is enhanced, the risk of scratches is reduced, the packaging workpieces are allowed to have a certain fault tolerance space when placed, and the environment with low operation precision is adapted.

[0081] It should be emphasized that the elastic modulus of the buffer 12 is less than the elastic modulus of the workbench 11, and the rigid-flexible combined structure balances the stability of the overall device and the local buffering performance. The buffer 12 with low elasticity undertakes the buffering and vibration absorption tasks, reduces the mechanical impact of the packaging workpieces caused by operation errors, reduces the dependence of the device on the placement precision, reduces the damage rate of the packaging workpieces, and improves the yield rate and production efficiency.

[0082] In general, the present scheme embeds the buffer 12 in the loading groove 111 on one side of the workbench 11, and the surface of the buffer 12 is provided with a plurality of adsorption grooves 121, so as to realize the flexible bearing and fault-tolerant positioning of the packaging workpieces. The present scheme is suitable for use in low-precision operation scenarios, significantly buffers the mechanical impact of the packaging workpieces during placement and handling, reduces scratches and pin deformation between the packaging workpieces and the hard metal table, reduces the damage risk of the packaging workpieces, and improves the yield rate and production efficiency.

[0083] It should be emphasized that the groove wall of the outwardly expanded adsorption groove 121 effectively expands the fault tolerance range of the placement of the packaging workpiece 21, reduces the risk of misplacement and scratches of the packaging workpiece 21 caused by placement deviation, improves the self-guiding capability and automatic sliding-in and sliding-out performance of the packaging workpiece 21, significantly reduces the dependence of the device on the placement precision, and improves the applicability and production efficiency of the sorting device in a low-precision operation environment.

[0084] It should be emphasized that in the same direction, the size of the packaging workpiece 21 is greater than the size of the groove bottom of the adsorption groove 121, and the size of the packaging workpiece 21 is less than the size of the slot of the adsorption groove 121. The size of the packaging workpiece 21 is between the size of the groove bottom and the size of the slot of the adsorption groove 121, so as to ensure that the packaging workpiece 21 can enter the adsorption groove 121 through the slot, but cannot slide out from the groove bottom position, realize effective limiting and anti-displacement of the packaging workpiece 21, and prevent the packaging workpiece 21 from falling off due to operation errors or vibration in combination with the deformation absorption of the elastic buffer 12.

[0085] Optionally, in the same direction, the ratio of the positioning accuracy of the mechanical arm to the size of the packaging workpiece 21 is in the range of 0.08-0.15, ensuring that the error of the mechanical arm placement action is within the tolerable range of the size of the packaging workpiece 21. It can be understood that in the present scheme, if the width of the packaging workpiece 21 is 5mm, the positioning accuracy of the corresponding mechanical arm in the present scheme can be between ±0.4mm and ±0.75mm, greatly reducing the demand for positioning accuracy of the mechanical arm, so as to meet the demand for low-precision assembly. By limiting the ratio of the positioning accuracy to the size of the packaging workpiece 21, combined with the outwardly expanding groove wall of the adsorption groove 121 and the elastic design of the buffer 12, the tolerance of the system to the positioning error is improved, and it is ensured that the packaging workpiece 21 can be safely and accurately placed into the adsorption groove 121, avoiding damage and misplacement caused by positioning error.

[0086] In general, by designing an integrated packaging workpiece sorting jig 1, including a workbench 11 and a buffer 12 provided in the object carrying groove 111 of the workbench 11, the buffer 12 is provided with a plurality of adsorption grooves 121, the groove wall of the adsorption groove 121 is outwardly expanding, the size of the groove opening is larger than the size of the groove bottom, and the size of the packaging workpiece 21 is between the size of the groove bottom and the size of the groove opening, combined with the rigid-flexible combined design that the elastic modulus of the buffer 12 is smaller than the elastic modulus of the workbench, the ratio of the positioning accuracy of the mechanical arm to the size of the packaging workpiece 21 is in the range of 0.08-0.15, so as to realize efficient and stable carrying and sorting of the packaging workpiece 21 in the case of low positioning accuracy of the mechanical arm.

[0087] The present scheme effectively reduces the placement error of the packaging workpiece 21 caused by insufficient positioning accuracy of the mechanical arm, avoids displacement, scratching and damage of the packaging workpiece 21 during sorting; the elastic property of the buffer 12 provides buffering and adsorption functions to protect the integrity of the packaging workpiece 21; the rigidity of the workbench 11 can ensure the stability of the overall structure, and also can maintain the accuracy of the equipment under repeated positioning, improve the yield and production efficiency of the packaging workpiece sorting.

[0088] In some embodiments, as shown in Figure 6 The groove bottom of the adsorption groove 121 is provided with a support protrusion 1211 in the form of a ring, which forms a closed ring structure around the center of the groove bottom of the adsorption groove 121. The radially inner side of the support protrusion 1211 is provided with a first groove 1212, and the first hole section 131 is arranged at the groove bottom of the first groove 1212 for negative pressure passage. The radially outer side of the support protrusion 1211 is provided with a second groove 1213, which surrounds the outer side of the support protrusion 1211 to form a multi-layer structure of the groove bottom. When the packaging workpiece 21 is located in the adsorption groove 121, the packaging workpiece 21 is in contact with the support protrusion 1211 to realize direct support.

[0089] The annular support protrusion 1211 realizes stable support of the packaging workpiece 21. The support protrusion 1211 serves as a bearing structure of the groove bottom of the adsorption groove 121, surrounds the bottom edge of the packaging workpiece 21, provides uniform support for the packaging workpiece 21, avoids direct contact of the packaging workpiece 21 with the groove bottom plane, reduces friction and wear, realizes multi-point contact through annular support, improves the stability and positioning accuracy of the packaging workpiece 21, and relieves shaking or tilting of the packaging workpiece 21 caused by vibration or mechanical impact.

[0090] The first groove 1212 is located radially inside the support protrusion 1211, and the first hole section 131 penetrates the groove bottom to form a key part of the negative pressure passage. The negative pressure is transmitted to the bottom of the packaging workpiece 21 through the first groove 1212 to realize effective adsorption. The design of the groove avoids complete blockage of the negative pressure passage by the packaging workpiece 21, ensuring smooth negative pressure and stable adsorption.

[0091] The second groove 1213 is located outside the support protrusion 1211 to form a multi-layer structure of the groove bottom, assist the elastic deformation of the buffer 12 and the distribution of airflow, enhance the overall elastic response of the buffer pad, absorb mechanical impact and error, promote uniform distribution of negative pressure airflow, and improve adsorption efficiency and stability.

[0092] The bottom of the packaging workpiece 21 directly contacts the support protrusion 1211 to form a mechanical support interface. Physical support prevents the packaging workpiece 21 from sliding or falling off when the negative pressure adsorption fails, improves the positioning repeatability and stability of the packaging workpiece 21.

[0093] In summary, through the structure design of the annular support protrusion 1211 and the first groove 1212 and the second groove 1213 radially inside and outside the support protrusion 1211, combined with the negative pressure passage formed by the first hole section 131, both mechanical stable support of the packaging workpiece 21 and effective transmission of negative pressure adsorption and uniform distribution of airflow are realized. The packaging workpiece 21 is in abutting contact with the support protrusion 1211, which avoids displacement and damage of the packaging workpiece 21 caused by insufficient negative pressure or positioning error, greatly improves the adaptability and sorting stability of the equipment in the environment with low positioning accuracy of the mechanical arm, and ensures the safe bearing and high yield of the packaging workpiece 21.

[0094] Optionally, the modular design facilitates maintenance and replacement, improving the adaptability and economic benefits of the equipment.

[0095] In some embodiments, as shown in Figure 2 Optionally, a plurality of adsorption grooves 121 are arranged at intervals on the surface of the buffer 12, that is, an interval groove 122 is arranged between two adjacent adsorption grooves 121. The interval groove 122 is a groove structure on the buffer 12, which is separated from the adsorption groove 121 but is coherent on the buffer 12 as a whole.

[0096] Optionally, the size of the spacing groove 122 can be the same as that of the adsorption groove 121, and can also be smaller or larger than that of the adsorption groove 121. The specific width and depth are determined according to design requirements.

[0097] It can be understood that the spacing groove 122 provides a buffer space between adjacent adsorption grooves 121, avoiding mutual collision of the packaging workpieces due to errors when being placed or moved. In use scenarios with low operation precision, the packaging workpieces can have a large range of lateral deviation. The spacing groove 122 effectively prevents scratching and damage between the packaging workpieces, and improves the stability of the overall bearing of the packaging workpieces.

[0098] The spacing groove 122 acts as a mechanical partition belt, blocking and attenuating the propagation of vibration and shock waves on the surface of the buffer piece 12, reducing the risk of resonance and mutual collision between the packaging workpieces caused by vibration, and enhancing the stability of the sorting equipment and the protection capability of the packaging workpieces.

[0099] Optionally, the spacing groove 122 can serve as an airflow channel, allowing the airflow of negative pressure adsorption to be uniformly distributed to each adsorption groove 121, ensuring the stability of negative pressure in each adsorption groove 121, and improving the reliability of adsorption of the packaging workpieces, especially when there is a deviation in the position of the packaging workpiece.

[0100] Optionally, the spacing groove 122 provides a cleaning channel on the surface of the buffer piece 12, facilitating the removal of dust and debris, reducing the impact of pollutant accumulation on the placement and adsorption of the packaging workpieces, and ensuring long-term stable operation of the equipment.

[0101] It can be understood that the adsorption grooves 121 and the spacing grooves 122 are alternately arranged, the width of the spacing groove 122 is at least equal to or greater than the edge fillet radius of the adsorption groove 121, ensuring that the boundaries of the two are clear and have a buffer space, the depth of the spacing groove 122 is similar to that of the adsorption groove 121, ensuring uniformity of the surface elasticity and overall flatness of the buffer piece 12, and the adsorption groove 121 and the spacing groove 122 are both recessed parts of the buffer piece 12, ensuring the overall integrity and elastic continuity of the material.

[0102] In summary, by setting the spacing groove 122, the surface of the buffer piece 12 forms a plurality of adsorption regions that are mutually isolated and have uniform airflow distribution, effectively improving the fault tolerance and adsorption stability of the placement of the packaging workpieces, allowing a large placement error of the packaging workpieces in the X direction or the Y direction of the machining table without affecting the overall bearing and adsorption effect, preventing mutual scratching and damage between the packaging workpieces, and enhancing the adaptability of the equipment and the yield of production.

[0103] In some embodiments, the surface of the buffer piece 12 is provided with a plurality of adsorption grooves 121, and the groove wall of each adsorption groove 121 is outwardly expanded, i.e., the size of the groove opening is larger than that of the groove bottom. Specifically, the side wall of the adsorption groove 121 is inclined outwardly or has a trumpet shape, so that the opening of the groove is wider than the groove bottom.

[0104] The outwardly expanding groove wall forms a gradually narrowing guide structure, which facilitates the smooth sliding of the packaging workpiece into the groove even if there is a certain horizontal deviation when placed. In an environment with low operation precision, the error range of the packaging workpiece when placed is large. The wide slot design effectively expands the falling area of the packaging workpiece, reducing the risk that the packaging workpiece cannot accurately enter the adsorption groove 121 due to placement deviation.

[0105] It can be understood that the packaging workpiece is automatically guided into the groove bottom at the slot, realizing automatic alignment, improving positioning accuracy and stability.

[0106] In addition, the outwardly expanding groove wall avoids sharp contact between the edge of the packaging workpiece and the groove wall, reduces friction and scratching risk, reduces mechanical damage to the pins and packaging side of the packaging workpiece, especially when the packaging workpiece is slightly shaken or collided due to operation error, prolongs the service life of the packaging workpiece and the buffer 12, and improves the yield of the packaging workpiece.

[0107] The outwardly expanding groove wall design facilitates the smooth sliding of the packaging workpiece into and out of the adsorption groove 121 under the push of the mechanical arm or automatic feeding mechanism, reduces the packaging workpiece jamming phenomenon, improves the automation efficiency and stability of the sorting equipment, reduces the requirement of the equipment on the placement precision and action stability of the mechanical arm, and adapts to the low-precision operation environment.

[0108] Optionally, the groove wall is generally inclined by 5°~20° relative to the surface of the buffer 12.

[0109] Optionally, the size of the slot is greater than the size of the groove bottom, and the width of the slot is 0.5mm~2mm wider than the groove bottom, to ensure sufficient guiding space.

[0110] In summary, the outwardly expanding groove wall of the adsorption groove 121 effectively expands the fault tolerance range of the placement of the packaging workpiece, reduces the risk of misalignment and scratching of the packaging workpiece due to placement deviation, improves the self-guiding capability and automatic sliding-in and sliding-out performance of the packaging workpiece, significantly reduces the dependence of the equipment on the placement precision, and improves the applicability and production efficiency of the sorting equipment in a low-precision operation environment.

[0111] In some embodiments, optionally, the inner surface of the groove wall of the adsorption groove 121 is inclined, i.e. not parallel to the direction of the slot, to facilitate the balance between high fault tolerance of the placement of the packaging workpiece and effective positioning.

[0112] Optionally, in the adsorption groove 121 provided on the surface of the buffer 12, the two opposite groove walls are outwardly expanding, and the included angle between the two groove walls is controlled within the range of 30°~90°, which is defined as the opening angle between the two groove walls, determines the width of the slot and the guiding capability, and balances the opening width of the slot and the precision requirement of the positioning of the packaging workpiece.

[0113] When the included angle is large, close to 90°, the notch is wider, the packaged workpiece is easier to slide into the groove when placed, and it is suitable for scenarios with low positioning accuracy and large fault tolerance range. When the included angle is small, close to 30°, the notch is narrower, the positioning is more accurate, and it is suitable for applications with high requirements for positioning of packaged workpieces.

[0114] The groove wall in the included angle range forms a gradually narrowing guide channel, guiding the packaged workpiece to slide from the wider notch to the narrower groove bottom, achieving automatic centering, improving the self-correction ability of the packaged workpiece during placement, reducing misplacement and stacking caused by placement deviation, enhancing the stability of the packaged workpiece in the adsorption groove 121, and avoiding displacement of the packaged workpiece due to vibration or operation error.

[0115] Through the above-mentioned included angle, the direct impact area of the packaged workpiece and the groove wall is reduced, sharp contact is avoided, the risk of damage to the packaged workpiece pins and the packaged side is reduced, and the integrity of the packaged workpiece is protected.

[0116] In summary, by controlling the included angle of the adsorption groove 121 relative to the groove wall within the range of 30°~90°, the present scheme realizes the balance between high fault tolerance and effective positioning of the packaged workpiece placement. The larger included angle expands the fault tolerance space of the packaged workpiece placement, facilitating the smooth entry and self-positioning of the packaged workpiece in a low-precision operation environment; the smaller included angle improves the positioning accuracy, prevents the packaged workpiece from sliding horizontally, significantly improves the adaptability and stability of the sorting equipment, effectively reduces the risk of scratching and damage of the packaged workpiece, and improves the yield and production efficiency.

[0117] In some embodiments, as shown in Figure 5 and Figure 6 , the through hole 13 in the present scheme is composed of a first hole section 131 and a second hole section 132, and the two hole sections are connected, the first hole section 131 is arranged in the buffer 12, and the first hole section 131 is connected with the groove bottom of the adsorption groove 121 on the surface of the buffer 12, forming the initial part of the negative pressure passage, the second hole section 132 is arranged in the workbench 11, and is connected with the first hole section 131, constituting a complete channel.

[0118] The first hole section 131 is connected with the groove bottom of the adsorption groove 121, ensuring that the negative pressure can directly act on the bottom surface of the packaged workpiece in the adsorption groove 121, improving the adsorption effect. The first hole section 131 is connected with the second hole section 132, forming a continuous 3 passage from the buffer 12 to the workbench. The second hole section 132 is arranged in the workbench, relying on the rigid structure of the workbench to ensure the stability and sealing performance of the through hole 13, and facilitating the connection of the vacuum negative pressure source.

[0119] It can be understood that the axis of the through hole 13 is aligned with the position of the adsorption groove 121, ensuring that the negative pressure is accurately transmitted to the packaged workpiece bearing position.

[0120] The through hole 13 forms a connection passage of the adsorption groove 121 and the negative pressure system of the workbench, and firmly fixes the packaging workpiece through negative pressure adsorption. Even in the case of low positioning accuracy, negative pressure adsorption can still effectively prevent the packaging workpiece from slipping or falling off, improve the sorting stability, and the negative pressure adsorption is combined with the elastic buffer 12 to double guarantee the safe bearing of the packaging workpiece.

[0121] The negative pressure directly acts on the bottom of the packaging workpiece through the through hole 13, enhances the contact stability of the packaging workpiece and the buffer 12, resists the displacement of the packaging workpiece caused by the placement error and vibration of the mechanical arm, reduces the risk of scratching and pin deformation of the packaging workpiece, and improves the fault tolerance of the packaging workpiece placement and the overall reliability of the equipment.

[0122] The through hole 13 is divided into a first hole section 131 arranged on the buffer 12 and a second hole section 132 arranged on the workbench, which has a reasonable structure distribution and takes into account the elastic buffering and rigid support. The first hole section 131 in the buffer 12 ensures the integrity of the flexible material and the smoothness of the adsorption passage, and the second hole section 132 in the workbench provides mechanical strength and a stable negative pressure connection interface to ensure the stable work of the negative pressure system.

[0123] In summary, the through hole 13 design connects the groove bottom of the adsorption groove 121 of the buffer 12 and the internal negative pressure system of the workbench, realizes effective negative pressure adsorption and fixation, significantly improves the fixing stability of the packaging workpiece in the environment with low operation precision, prevents the packaging workpiece from slipping and scratching due to positioning error, cooperates with the elastic bearing of the buffer 12, forms a high-fault-tolerant and high-protective packaging workpiece sorting bearing platform, and greatly improves the yield and production efficiency.

[0124] In some embodiments, the workbench 11 is optionally made of metal material to ensure the rigidity and stability of the overall structure, and the buffer 12 is made of elastic material with a significantly lower elastic modulus than the metal workbench, which has good elasticity and buffering performance. Optionally, the material of the workbench 11 is metal, and the material of the buffer 12 is rubber or thermoplastic elastomer.

[0125] The metal workbench provides rigid support, and the rubber buffer 12 provides flexible buffering. The two are combined to build a rigid and flexible packaging workpiece bearing platform. The metal workbench ensures the overall stability of the equipment, bears mechanical load and vibration, and guarantees structural precision. The rubber buffer 12 absorbs impact force during the placement and handling of the packaging workpiece, reduces direct contact between the packaging workpiece and the hard metal, and reduces scratching and pin damage.

[0126] The elastic properties of the rubber buffer 12 compensate for errors during placement by a mechanical arm or manually, reducing the dependence on high-precision positioning of the equipment. The rubber buffer 12 can be designed as a detachable module for easy replacement and maintenance. The buffer 12 may be worn or contaminated due to long-term use, and is easy to replace to ensure continuous and efficient operation of the equipment.

[0127] The buffer 12 is embedded in the workpiece slot 111 of the metal workbench, and the two are stably connected through mechanical cooperation. The elastic modulus of the rubber buffer 12 is smaller than that of the metal workbench, thereby realizing functional partitioning of rigidity and flexibility. The through hole 13 structure penetrates the rubber buffer 12 and the metal workbench, thereby realizing stable transmission of the negative pressure adsorption function.

[0128] Optionally, the packaged workpiece can be flexibly carried by the buffer 12 even under a placement error in the range of ±0.5 mm or even larger, thereby avoiding damage and improving the stability of placement of the packaged workpiece and the adsorption effect, and increasing the fault tolerance and yield of the production line.

[0129] In general, the workbench made of metal material is combined with the buffer 12 made of rubber material to construct a rigid-flexible combined platform for carrying and adsorbing the packaged workpiece. The metal workbench provides a solid and stable mechanical foundation, and the rubber buffer 12 provides flexible buffering and fault-tolerant positioning. The risk of scratching and pin deformation of the packaged workpiece caused by insufficient operation precision is significantly reduced, and the applicability and production efficiency of the equipment are improved. The equipment is particularly suitable for sorting needs of low-precision operation environment and diversified packaged workpiece specifications.

[0130] In some embodiments, the surface of the buffer 12 is provided with a plurality of adsorption grooves 121, and a transition fillet or a transition inclined surface is arranged between the groove bottom and the groove wall of each adsorption groove 121, that is, the connection between the groove bottom and the groove wall is not a right angle, but a smooth curve or an inclined surface transition. The transition fillet or inclined surface design effectively eliminates the sharp geometric edges at the junction of the groove bottom and the groove wall, avoids stress concentration, reduces the local pressure of the packaged workpiece pin or the packaged edge when contacting the groove wall, reduces the risk of scratching and mechanical damage, and protects the packaged workpiece pin from deformation or fracture due to stress concentration at the sharp edge.

[0131] The smooth transition surface is beneficial for the packaged workpiece to smoothly slide into the bottom of the adsorption groove 121 when placed, avoids jamming, improves the automatic introduction capability of the packaged workpiece, reduces the probability of misplacement and stacking caused by placement error, makes the packaged workpiece more easily realize automatic alignment and stable positioning in the adsorption groove 121, and improves the sorting efficiency and yield.

[0132] The fillet or inclined surface design avoids the position where dust and debris are easily accumulated at the junction of the groove bottom and the groove wall, reduces the instability of the packaged workpiece placement or adsorption failure caused by the accumulation of pollutants, facilitates cleaning and maintenance, and prolongs the service life of the buffer 12.

[0133] It can be understood that the transition fillet or inclined surface is located at the junction of the groove bottom and the groove wall of the adsorption groove 121, forming a smooth curved surface or an inclined surface. The radius or inclined surface angle is optimized according to the size of the packaged workpiece and the material elasticity of the buffer 12, to ensure the structural continuity and elastic uniformity of the groove wall and the groove bottom, and prevent local rigidity from suddenly changing.

[0134] The transition fillet or transition chamfer is integrally formed with the overall structure of the buffer 12, ensuring the overall elasticity and mechanical strength of the material.

[0135] In general, the transition fillet or transition chamfer is arranged between the groove bottom and the groove wall of the adsorption groove 121, effectively reducing the local stress and friction when the packaging workpiece contacts the groove wall, improving the smoothness and self-positioning ability of the packaging workpiece placement, significantly reducing the risk of scratches and pin damage caused by operation errors, improving the stability of the packaging workpiece bearing and the fault tolerance of the sorting equipment, especially suitable for production environments with low positioning accuracy, ensuring production efficiency and yield.

[0136] In some embodiments, optionally, as shown in Figure 11 The surface layer of the rubber pad, i.e. the contact surface of the buffer 12, is provided with a frosted layer 14, which can be a micro-texture or frosted surface formed by surface microstructure or roughening treatment. The texture or frosted surface is designed on the packaging workpiece bearing surface of the buffer 12, i.e. the surface or peripheral area of the adsorption groove 121. The texture of the frosted layer 14 is fine, which ensures that the friction is increased while not causing scratches or damage to the surface of the packaging workpiece or the pins.

[0137] The micro-texture or frosted surface increases the friction coefficient of the contact surface between the packaging workpiece and the buffer 12, prevents the packaging workpiece from sliding due to vibration or operation error when falling into the adsorption groove 121 or the surface of the buffer 12, improves the stability of the packaging workpiece, and reduces the misalignment or stacking of the packaging workpiece caused by slight lateral displacement.

[0138] The texture treatment is fine and soft, avoiding the generation of sharp edges or hard points, preventing the packaging workpiece, especially the pin surface, from being scratched, scratched or deformed, maintaining the appearance and performance integrity of the packaging workpiece, and improving the yield.

[0139] In general, the surface layer of the rubber pad is designed with a micro-texture or frosted surface, which effectively improves the friction between the packaging workpiece and the buffer 12, prevents the packaging workpiece from sliding and misaligning due to slight lateral displacement, and avoids mechanical damage to the surface of the packaging workpiece and the pins. Combined with the elastic bearing of the buffer 12, the fault tolerance and protection effect of the packaging workpiece placement are significantly enhanced, greatly improving the stability and production yield of the equipment in a low positioning accuracy environment.

[0140] In some embodiments, optionally, as shown in Figure 7 and Figure 8As shown, the base structure 15 is the basic support component of the device, provided with an assembly slot 151 and a vacuum channel 152, which are in communication with each other. The assembly slot 151 is provided on the first surface of the base structure 15 for mounting the workbench, and the vacuum channel 152 is provided on the second surface of the base structure 15 and communicates with the assembly slot 151 to form a negative pressure conveying path. The workbench is provided on the side of the base structure 15 provided with the assembly slot 151 and is detachably connected with the base structure 15 through the assembly slot 151.

[0141] The assembly slot 151 is located on the first surface of the base structure 15, and the workbench is mounted in the assembly slot 151 to ensure the fixation and positioning of the workbench. The vacuum channel 152 is located on the second surface of the base structure 15 and communicates with the assembly slot 151 to form a negative pressure path through the base structure. The workbench and the base structure 15 are detachably connected through the assembly slot 151, which facilitates the disassembly, maintenance and replacement of the workbench. The communication between the assembly slot 151 and the vacuum channel 152 ensures that the negative pressure can be transmitted from the vacuum channel 152 of the base structure to the workbench and the buffer 12 and the adsorption slot 121 thereon.

[0142] It can be understood that the base structure 15 serves as the foundation of the device, and the assembly slot 151 provides accurate installation and positioning and stable support for the workbench, ensures the repeated positioning accuracy between the workbench and the base structure, reduces the positioning deviation of the packaged workpiece caused by assembly errors, improves the rigidity and stability of the overall structure of the device, and reduces the influence of vibration.

[0143] The vacuum channel 152 is provided on the second surface of the base structure 15 and communicates with the assembly slot 151 to form a complete negative pressure path. The negative pressure is transmitted from the base structure 15 to the workbench and the adsorption slot 121 of the buffer 12 to realize stable adsorption of the packaged workpiece, ensure the sealing and smoothness of the negative pressure system, and improve the adsorption efficiency and reliability.

[0144] The detachable connection design of the workbench and the base structure 15 facilitates on-site disassembly and maintenance. When the buffer 12 or the workbench is worn or damaged, it can be quickly disassembled and replaced, reducing the downtime of the device and improving the maintenance convenience and service life of the device.

[0145] The stable connection of the base structure 15 and the workbench and the negative pressure channel ensure the flexible bearing of the buffer 12 and the adsorption slot 121, realize overall fault tolerance, reduce the dependence on high-precision mechanical arms or placement devices, effectively reduce the problems of scratching and pin deformation of the packaged workpiece caused by positioning errors, and improve the yield.

[0146] In general, the base structure 15 is provided with a communication assembly slot 151 and a vacuum channel 152. The assembly slot 151 is located on the first surface of the base structure for workbench installation, and the vacuum channel 152 is located on the second surface to form a negative pressure passage. The workbench is detachably connected to the base structure through the assembly slot 151. By combining mechanical rigid support and negative pressure adsorption function, the stability of the workbench is ensured, and the efficient operation of the negative pressure system is ensured. The applicability of the equipment in a low positioning accuracy environment and the protection ability of the packaged workpiece are greatly improved, and the production efficiency and the good product rate are ensured.

[0147] In some embodiments, as shown in Figure 8 The first positioning member 161 is arranged in the assembly slot 151 of the base structure 15, and is usually in the form of a protrusion, a groove, a pin hole or the like, and is used for positioning cooperation with the buffer member 12. The second positioning member 162 is arranged on the outer surface of the buffer member 12, and has a shape and size matched with the first positioning member 161 to realize cooperative positioning. The first positioning member 161 and the second positioning member 162 limit the relative position of the workbench 11 in the assembly slot 151, so as to prevent the buffer member 12 from being displaced or rotated.

[0148] It can be understood that the first positioning member 161 is fixed to the inner wall or the bottom of the assembly slot 151, and serves as a positioning reference for the buffer member 12. The second positioning member 162 is arranged on the outer surface of the workbench 11, and is usually in the form of a groove, a protrusion or a tongue, and corresponds to the first positioning member 161. Through the cooperation of the first positioning member 161 and the second positioning member 162, the workbench 11 is accurately positioned and stably fixed in the assembly slot 151. The positioning member design ensures the repeated positioning accuracy of the buffer member 12 during installation, and facilitates disassembly and installation.

[0149] The positioning member cooperation prevents the workbench 11 from sliding, deviating or rotating due to vibration, mechanical impact or operation error during use, so as to ensure that the workbench 11 is always in the designed bearing position, and to ensure the stability and positioning accuracy of the packaged workpiece. Quality problems such as scratching and pin deformation of the packaged workpiece caused by displacement of the workbench 11 are avoided.

[0150] The positioning member realizes quick and accurate installation of the workbench 11, reduces installation error, and facilitates maintenance or replacement of the workbench 11. The positioning member is accurate, shortens downtime, and improves maintenance efficiency and service life of the equipment.

[0151] The positioning member ensures stable fixation of the workbench 11, cooperates with the elasticity of the buffer member 12 and the structure of the adsorption groove 121, improves the fault tolerance of the positioning of the packaged workpiece as a whole, reduces the positioning error of the packaged workpiece caused by the position deviation of the buffer member 12, reduces the risk of damage to the packaged workpiece, and enhances the adaptability of the equipment to low-precision mechanical arms or operators.

[0152] In general, the first positioning member 161 is arranged in the assembly groove 151, and the second positioning member 162 is arranged on the workbench 11. The relative positions of the workbench 11 and the assembly groove 151 are limited by cooperation, so as to ensure stable installation and repeated positioning of the workbench 11, prevent displacement of the workbench 11 under vibration or mechanical impact, and ensure accurate bearing and adsorption of the packaging workpiece on the buffer 12. In combination with the elastic buffering and the adsorption groove 121 of the buffer 12, the reliability and packaging workpiece protection capability of the equipment in a low positioning precision environment are significantly improved, and the yield and production efficiency are improved.

[0153] In some embodiments, optionally, as shown in Figure 9 The adhesive layer 17 is arranged between the inner wall of the assembly groove 151 of the base structure 15 and the outer surface of the buffer 12, and serves as an adhesive medium for the two. The adhesive layer 17 is made of an adhesive with good adhesion and certain elasticity, and has fixing effect and buffering performance. The thickness of the adhesive layer 17 is uniform, so as to ensure close fitting between the buffer 12 and the assembly groove 151.

[0154] The adhesive layer 17 is arranged between the inner wall of the assembly groove 151 and the outer surface of the buffer 12, and covers the entire contact surface or the key positioning area. The adhesive layer 17 is closely combined with the surfaces of the assembly groove 151 and the buffer 12, so as to form a stable adhesive interface. The adhesive layer 17 is used in cooperation with the first positioning member 161 and the second positioning member 162, so as to enhance the fixing and positioning stability of the buffer 12.

[0155] It can be understood that the adhesive layer 17 prevents the buffer 12 from sliding, loosening or falling off in the assembly groove 151 through adhesion, improves the installation stability of the buffer 12, avoids relative displacement caused by vibration or mechanical impact, ensures the stability of the bearing surface of the packaging workpiece, and reduces the risk of scratching and pin deformation of the packaging workpiece.

[0156] The elastic property of the adhesive layer 17 can compensate for the size tolerance and small gap between the assembly groove 151 and the buffer 12 to some extent, improve the sealing and flatness of the overall structure, reduce vibration transmission, enhance the buffering effect of the buffer 12, and further protect the packaging workpiece.

[0157] In general, the adhesive layer 17 is arranged between the assembly groove 151 and the buffer 12, and is used to fix the buffer 12 through adhesion, so as to improve the stability and positioning precision of the buffer 12 in the assembly groove 151. The adhesive layer 17 not only prevents the buffer 12 from sliding due to vibration or mechanical impact, but also compensates for the assembly gap, so as to enhance the sealing and flatness of the overall structure. In combination with the elastic buffering and the adsorption groove 121 of the buffer 12, the packaging workpiece protection capability and production efficiency of the equipment in a low positioning precision environment are significantly improved, the damage rate is reduced, and the yield is improved.

[0158] As shown in Figure 12 ,Figure 13 and Figure 14 As shown, another embodiment of this application provides a packaged workpiece sorting component 2, including a plurality of packaged workpieces 21 and a packaged workpiece sorting fixture 1. The packaged workpiece 21 includes a packaged workpiece body 211 and pins 212 disposed on the packaged workpiece body 211. It should be emphasized that the pins 212 of the packaged workpiece body 211 directly contact the bottom of the adsorption tank 121, so that the packaged workpiece 21 is stably positioned in the tank, preventing the packaged workpiece 21 from being displaced or tilted due to vibration or operation error during the sorting process. By the contact between the pin side of the packaged workpiece and the bottom of the tank, the pins 212 of the packaged workpiece 21 are prevented from bending, breaking or being damaged due to suspension or unstable placement, thereby improving the protection effect of the packaged workpiece.

[0159] The fit design between the packaged workpiece 21 and the bottom of the adsorption tank 121, combined with the elasticity and negative pressure adsorption structure of the buffer 12, enhances the fixation and positioning accuracy of the packaged workpiece 21. Even in environments with low positioning accuracy, it can effectively ensure the stable bearing and sorting accuracy of the packaged workpiece.

[0160] It is understandable that the structure of this solution is suitable for sorting various packaged workpieces 21 with pins, especially packaged workpieces with specific requirements for the position and orientation of pins 212, thereby improving the versatility and applicability of the equipment.

[0161] Since the packaged workpiece sorting assembly 2 includes the packaged workpiece sorting fixture 1, it has the beneficial effects of any of the packaged workpiece sorting fixtures 1 mentioned above, which will not be elaborated here.

[0162] Among them, such as Figure 12 As shown, the encapsulated workpiece body 211 is in direct contact with the bottom of the adsorption tank 121, and the pins 212 are set upwards, thereby achieving the effect of negative pressure adsorption.

[0163] like Figure 13 As shown, pin 212 is in direct contact with the bottom of the adsorption tank 121, with pin 212 facing downwards. At this time, negative pressure can be used to fix the encapsulated workpiece 21 by sealing the encapsulated workpiece 21 with the adsorption tank 121.

[0164] like Figure 14 As shown, the encapsulated workpiece body 211 is in direct contact with the bottom of the adsorption tank 121, and the pins 212 are set downwards, thereby achieving the effect of negative pressure adsorption.

[0165] In some embodiments, optionally, at least part of the encapsulated workpiece 21 is disposed in the adsorption groove 121, that is, the encapsulated workpiece 21 is partially embedded in the adsorption groove 121 of the buffer 12, rather than being completely placed outside the groove, and the length of the pins 212 of the encapsulated workpiece 21 is less than the depth of the adsorption groove 121, so as to ensure that the pins 212 of the encapsulated workpiece will not push out of the bottom of the groove or conflict with the bottom of the groove.

[0166] The encapsulation workpiece 21 is partially embedded in the adsorption groove 121, and the groove wall and the groove bottom support the lateral and bottom of the encapsulation workpiece 21, limit the horizontal and vertical movement of the encapsulation workpiece 21, reduce the shaking and tilting of the encapsulation workpiece 21 during placement and handling, improve the positioning accuracy of the encapsulation workpiece 21, and through the embedded bearing, the stress of the encapsulation workpiece is more uniform, the local stress concentration is reduced, and the structure of the encapsulation workpiece 21 is protected.

[0167] The depth of the adsorption groove 121 is greater than the length of the pin 212 of the encapsulation workpiece 21, so that the pin 212 will not be deformed or broken due to touching the groove bottom, the possibility of top and bottom impact of the pin 212 is reduced, the deformation and damage risk of the pin 212 is reduced, the electrical performance of the encapsulation workpiece is stable, and the yield rate of sorting is improved.

[0168] Optionally, since the encapsulation workpiece 21 is embedded in the groove, the contact stability of the encapsulation workpiece and the buffer 12 is enhanced through the through hole 13 negative pressure adsorption, the negative pressure acts on the bottom surface of the encapsulation workpiece, the embedded groove wall limits the horizontal movement, and the double fixation improves the bearing stability, reduces the risk of displacement of the encapsulation workpiece caused by mechanical vibration or placement error.

[0169] The encapsulation workpiece 21 is embedded in the adsorption groove 121, the groove wall closely contacts the side surface of the encapsulation workpiece or maintains a small gap, lateral support is achieved, one side of the pin of the encapsulation workpiece faces the groove bottom of the adsorption groove 121, and the length of the pin is less than the depth of the groove, so that the pin will not contact or protrude from the groove bottom, the groove bottom of the adsorption groove 121 is attached to the pin surface of the encapsulation workpiece, and the effective transmission of negative pressure adsorption is ensured.

[0170] In summary, by designing that at least part of the encapsulation workpiece 21 is located in the adsorption groove 121, and the length of the pin of the encapsulation workpiece is less than the depth of the adsorption groove 121, the positioning stability and protection performance of the encapsulation workpiece 21 on the workbench 11 are significantly improved. The encapsulation workpiece 21 is embedded in the groove, cooperates with the expanded groove wall and negative pressure adsorption, realizes multi-dimensional fixation of the encapsulation workpiece, reduces the risk of displacement and pin damage of the encapsulation workpiece caused by operation error and vibration, and greatly improves the applicability and production yield rate of the equipment in the low positioning accuracy environment.

[0171] Another embodiment of the present application provides a kind of encapsulation workpiece sorting machine, comprising: mechanical arm;And above-mentioned encapsulation workpiece sorting fixture, mechanical arm is used to clamp encapsulation workpiece and moves to encapsulation workpiece sorting fixture.

[0172] The mechanical arm cooperates with the packaging workpiece sorting fixture to realize efficient automatic sorting of the packaging workpiece. The mechanical arm is responsible for clamping the packaging workpiece and moving it to the multiple adsorption grooves of the buffer in the loading groove of the packaging workpiece sorting fixture. The structural features of the packaging workpiece sorting fixture cooperate with the precise operation of the mechanical arm to realize stable bearing and buffer protection of the packaging workpiece, effectively reduce the influence of mechanical arm positioning error on the placement of the packaging workpiece, and improve the sorting efficiency and yield.

[0173] The mechanical arm, as an actuator in an automated device, has a clamping function and can accurately clamp the packaging workpiece to realize movement and placement in three-dimensional space. It is used to clamp the packaging workpiece, take it out from the upstream device or conveying system, move and accurately place it into the adsorption groove of the buffer in the loading groove of the packaging workpiece sorting fixture. It cooperates with the structural design of the sorting fixture to tolerate a certain range of positioning errors and ensure the safe and stable placement of the packaging workpiece.

[0174] The mechanical arm and the packaging workpiece sorting fixture are independent but cooperative components. After clamping the packaging workpiece, the mechanical arm moves along the predetermined trajectory above the loading groove of the packaging workpiece sorting fixture. The end clamping tool of the mechanical arm is aligned with the adsorption groove of the buffer of the packaging workpiece sorting fixture to ensure that the packaging workpiece can be accurately placed into the adsorption groove.

[0175] The ratio of the positioning accuracy of the mechanical arm to the size of the packaging workpiece is 0.08-0.15, which cooperates with the outwardly expanding groove wall of the adsorption groove and the elasticity of the buffer to slightly offset the error caused by the buffer.

[0176] In summary, this scheme realizes the automatic clamping, transfer and stable sorting of the packaging workpiece by combining the mechanical arm with the packaging workpiece sorting fixture. The mechanical arm is responsible for clamping and accurately placing the packaging workpiece into the buffer with multiple outwardly expanding adsorption grooves. The elasticity of the buffer and the structural design of the adsorption groove effectively buffer the positioning error of the mechanical arm, ensuring the safe bearing and stable positioning of the packaging workpiece. The overall system adapts to the condition that the ratio of the positioning accuracy of the mechanical arm to the size of the packaging workpiece is 0.08-0.15, improves the sorting efficiency and product yield, and is suitable for modern automated packaging workpiece sorting production lines.

[0177] Another embodiment of the present application provides a cutting and sorting all-in-one machine, comprising the above-mentioned packaging workpiece sorting fixture.

[0178] This scheme realizes the seamless connection of the cutting and sorting functions of the packaging workpiece by integrating the packaging workpiece sorting fixture in the cutting and sorting all-in-one machine. The packaging workpiece sorting fixture is located inside or at the end of the cutting and sorting all-in-one machine, serving as a bearing and sorting platform for the cut packaging workpiece. It effectively improves the automation level and efficiency of the cutting and sorting process, ensures that the cut packaging workpiece can be stably and accurately sorted and positioned, reduces workpiece damage and misplacement, and improves the yield and overall efficiency of the production line.

[0179] The packaging workpiece sorting fixture is a core bearing component of the cutting and sorting integrated machine, responsible for bearing, buffering and positioning of the packaging workpiece after cutting. The workbench provides rigid support to ensure the stability of the overall structure of the sorting fixture.

[0180] The packaging workpiece sorting fixture is fixedly installed at a specified position of the cutting and sorting integrated machine, usually downstream of the cutting area or at the entrance of the sorting module. The workbench is connected to the rack structure by means of bolts or quick buckles to ensure rigid support. The buffer is embedded in the workbench loading slot, and the two are tightly matched to ensure the stability of the buffer. The mechanical arm or automatic conveying device carries the cut packaging workpiece into the adsorption groove 121 of the sorting fixture to complete the sorting action.

[0181] The present scheme can integrate the packaging workpiece sorting fixture to realize seamless connection of the cutting and sorting process, reduce the intermediate handling link, improve production efficiency, and protect the packaging workpiece from damage by buffering the mechanical impact during cutting. The elastic modulus of the buffer is less than the rigidity modulus of the workbench, and the rigid-flexible combined structure effectively compensates for the positioning error during cutting and handling. The design of the adsorption groove matches the size of the workpiece to ensure stable bearing of the workpiece and reduce scratching and misplacement caused by positioning error.

[0182] In summary, the cutting and sorting integrated machine scheme integrates the above-mentioned packaging workpiece sorting fixture to effectively combine the cutting and sorting functions. The packaging workpiece sorting fixture provides stable bearing and buffering protection, and cooperates with the adsorption groove to significantly improve the sorting efficiency and protection effect of the cut packaging workpiece. The overall scheme is suitable for automatic high-efficiency production environment and significantly improves the stability and yield of the production line.

[0183] The present application also provides a specific embodiment, which provides one or more assembly areas on the upper surface of the workbench for installing a packaging workpiece bearing assembly of flexible material. A detachable rubber pad is fixed in the assembly area. The hardness of the rubber pad can be selected as Shore A60 industrial rubber or silicone to provide buffering while maintaining a certain supporting force and reducing pin contact damage.

[0184] A plurality of positioning grooves for placing the packaging workpiece are processed on the rubber pad: the inner wall of the groove adopts a rounded transition to avoid sharp edges; the groove size matches the packaging size of the packaging workpiece to ensure stability; and a through hole is provided at the bottom of the groove, with a diameter slightly smaller than the bottom surface size of the packaging workpiece.

[0185] The through hole can be used in conjunction with the vacuum adsorption system below to lift the packaging workpiece out of the groove by suction force when the packaging workpiece needs to be removed; or in conjunction with a ejector pin mechanism to lift the packaging workpiece from the bottom of the groove, reducing the opportunity for the clamp to directly contact the pins.

[0186] Optionally, the rubber pad is detachable, positioned by a positioning pin and fixed by a screw, facilitating replacement of the pad with different groove layouts according to different packaging specifications of the workpiece, and improving the adaptability of the equipment.

[0187] The rubber pad can be made of an anti-static material or coated with an anti-static coating on the surface to avoid static damage to the packaging workpiece during sorting.

[0188] 1. Due to the flexible cushioning effect of the rubber pad and the round corner design of the inner wall of the groove, the hard contact of the packaging workpiece pins with the edge of the groove during placement and handling is greatly reduced, and the risk of scratching is reduced.

[0189] 2. It effectively avoids problems such as pin bending and plating damage, significantly improving the product yield rate in the sorting link.

[0190] 3. The through hole cooperates with the vacuum suction or the thimble structure to make the packaging workpiece extraction process more stable, reduce the direct force of the clamp on the pin, and improve the operation efficiency.

[0191] 4. The modular design of the rubber pad can quickly replace different specifications of the groove layout, adapt to packaging workpieces of various packaging sizes, and reduce the cost of modification.

[0192] 5. The rubber pad has a certain vibration absorption capacity and can slow down the micro-motion of the packaging workpiece when the mechanical arm or feeding mechanism produces an impact, further reducing the probability of pin friction with the groove wall.

[0193] 6. Anti-static treatment can prevent potential damage to internal circuits of the packaging workpiece caused by static accumulation, improving the safety of the sorting process.

[0194] In one embodiment, the present application proposes an improved packaging workpiece sorting jig structure. The upper surface of the workbench is provided with one or more assembly areas for mounting flexible bearing assemblies. The rubber pad is fixed in the assembly area. The rubber pad can be made of anti-static silicone or industrial rubber, with moderate hardness, good sealing performance and vibration reduction characteristics. A plurality of positioning grooves for placing the packaging workpiece are formed on the rubber pad. The inner wall of the groove adopts a round corner or an inclined surface transition to avoid sharp edges. The groove size matches the packaging shape of the packaging workpiece to ensure stable positioning. A through hole is provided at the bottom of each groove, which communicates with the vacuum suction system below. The sealing performance of the rubber material enhances the negative pressure suction effect of the through hole, making the packaging workpiece more stable in the groove. The through hole can also cooperate with a mechanical thimble to lift from the bottom when the packaging workpiece is taken out, reducing the stress on the pin.

[0195] In addition, the rubber pad can be made of an anti-static material or coated with an anti-static coating on the surface to effectively suppress static accumulation and avoid static damage when the pin is placed downward.

[0196] The flexible bearing assembly adopts a detachable structure and is fixed through positioning pins and screws, so that different flexible bearing assemblies with different groove layouts can be replaced according to different packaging workpiece specifications, and the universality is improved.

[0197] The above technical scheme has the following remarkable effects: reducing scratches and improving the yield; the rubber material and the round groove structure effectively buffer the contact force between the packaging workpiece and the groove edge, avoiding scratches on the pins and the side surface of the packaging workpiece. The sealing performance of the rubber material is better than that of metal, and the negative pressure effect can be significantly enhanced by cooperating with the through-hole adsorption system, so as to prevent displacement of the packaging workpiece during sorting. The anti-static rubber pad effectively suppresses static electricity accumulation and protects the internal circuit of the packaging workpiece from damage caused by static discharge.

[0198] The rubber pad has a damping effect, forms soft contact when the packaging workpiece is placed, reduces the requirement for the vertical positioning accuracy of the equipment, and the universality of the equipment is higher.

[0199] The modular rubber pad can quickly replace different specifications of groove layouts, adapt to various packaging sizes, and has low maintenance and adjustment costs.

[0200] A specific embodiment is provided in the application, a rectangular assembly area (i.e., an assembly groove) is processed on a metal workbench (i.e., a base structure), the assembly area is 322 mm long and 140 mm wide, and is provided with two positioning pin holes. A rubber pad assembly (i.e., a packaging workpiece sorting fixture) with a thickness of 9 mm, a metal anti-static silicone rubber material is installed in the assembly area, positioned by the positioning pin, and fixed by an M5 screw. Matrix array grooves (i.e., object loading grooves) are processed on the rubber pad, each groove bottom is provided with a through hole with a diameter of 2 mm, which is communicated with the lower vacuum adsorption pipeline. The groove inner wall has a round corner with a radius of 0.5 mm, and the inlet slope angle is 30°. The structure can still ensure stable adsorption of the packaging workpiece under the condition that the positioning accuracy of the mechanical arm is ±0.5 mm, and the yield is improved by about 15%.

[0201] Optionally, the gap between the groove side wall and the packaging workpiece is 0.1 mm to 0.5 mm, allowing a certain positioning error.

[0202] The elastic modulus of the rubber pad is set to 0.5 MPa to 2 MPa, which facilitates the absorption of the impact caused by the placement error of the mechanical arm.

[0203] The groove depth is greater than the thickness of the packaging workpiece by 0.3 mm to 1 mm, which facilitates automatic sliding of the packaging workpiece into positioning.

[0204] The elastic modulus of the rubber pad is set to 0.5 MPa to 2 MPa, which can effectively absorb the impact caused by the Z-axis (vertical direction) positioning error, so that the packaging workpiece will not be damaged even if there is a slight height deviation.

[0205] The thickness of the rubber pad can be selected as 5mm~8mm, which ensures that the rubber pad can produce an elastic deformation interval of 0.2mm~1mm when the packaging workpiece is placed, allowing a larger vertical precision error.

[0206] The surface layer of the rubber pad is micro-textured or frosted, which increases friction but does not scratch the packaging workpiece, ensuring that even if there is slight lateral displacement when the packaging workpiece falls into the groove, it can be buffered and absorbed.

[0207] The gap between the groove and the side wall of the packaging workpiece is designed as 0.2mm~0.5mm (much larger than the conventional precision clamping of 0.05mm~0.1mm), allowing a placement error of ±0.2mm in the X or Y direction of the machining table.

[0208] The groove entrance is provided with a wide inclined surface (width 0.5mm~1mm, angle 20°~30°), which facilitates the automatic sliding of the packaging workpiece, and even if the position is deviated, it can be self-centered.

[0209] The depth of the groove is slightly larger than the thickness of the packaging workpiece by 0.5mm~1mm, so even if the packaging workpiece is placed with a tilt, it can completely accommodate the packaging workpiece to be sorted and prevent it from turning over.

[0210] The through hole diameter can be selected as 2mm~3mm, matched with rubber sealing, allowing a certain range of offset (such as ±0.5mm) of the bottom surface of the packaging workpiece to still ensure effective suction.

[0211] For larger packaging workpieces or multi-groove tables, multiple through holes or partitioned suction can be provided, each area is controlled separately, ensuring that even if the packaging workpiece is not completely centered, it can be firmly fixed by negative pressure.

[0212] The vacuum system has a negative pressure feedback adjustment function, which automatically adjusts the suction force according to the actual contact area of the packaging workpiece, adapting to the placement height, offset and other errors of the packaging workpiece.

[0213] The rubber pad is detachably connected to the workbench by buckle / positioning pin / magnetic attraction, etc., so even if there is a positioning deviation of ±1mm during assembly, it will not affect the functional cooperation of the groove and the through hole.

[0214] The bottom of the rubber pad is provided with a self-positioning boss or a limiting edge, which can automatically slide into the pre-set groove in the assembly area, facilitating quick replacement and alignment by manual operation.

[0215] The arrangement of the grooves on the rubber pad is designed with a wide tolerance (such as a tolerance of ±0.5mm), which is suitable for low-precision mechanical hands or manual batch feeding of packaging workpieces.

[0216] The side wall of the groove has a micro-inclined surface or an elastic limiting rib, which can automatically correct the posture when the packaging workpiece is placed slightly deviated.

[0217] The rubber pad surface is provided with a dustproof coating, allowing a certain amount of debris and dust to exist without affecting the normal placement and adsorption of the packaged workpiece.

[0218] The cooperation structure of the rubber pad and the base plate is designed as a loose fit, so that even if there is an assembly error during replacement, the overall function will not be affected.

[0219] By optimizing the elasticity and thickness of the rubber material, relaxing the cooperation tolerance of the groove and the packaged workpiece, designing an automatic alignment structure, and adjusting the coverage range of the adsorption system, the X / Y / Z direction precision requirement of the equipment for placing the packaged workpiece is reduced, which is suitable for low-precision automation or manual operation environment.

[0220] Even if there is a ±0.5mm error in placing the packaged workpiece (the conventional precision equipment usually requires ±0.1mm), the structure can still ensure the smooth positioning, adsorption and sorting of the packaged workpiece, and will not scratch or damage the pins and sides of the packaged workpiece, greatly improving the universality and actual production fault tolerance of the equipment.

[0221] Optionally, the rubber pad is made of different materials such as anti-static silicone, fluororubber, and polyurethane elastomer.

[0222] The surface of the rubber pad is treated with wear-resistant coating, hydrophilic / hydrophobic treatment, and micro-texturing.

[0223] The surface resistivity of the rubber pad is controlled at 106Ω-109Ω, which is suitable for electrostatic sensitive packaged workpieces.

[0224] The thickness of the rubber pad is 3mm, 5mm, 8mm, etc.

[0225] The hardness of the rubber pad is Shore A50, Shore A60, Shore A70, etc.
