Description

Technical Field

[0001] This utility model relates to the field of chip mounting equipment technology, and in particular to a material bin. Background Technology

[0002] In the chip mounter production line of the electronics manufacturing industry, the hopper, as a key piece of equipment that carries trays of electronic components, directly affects production efficiency and the degree of automation due to its structural rationality. Currently, the hoppers used in the market to supply electronic components to chip mounter production lines generally adopt a vertically spaced structure, that is, the trays are placed in layers vertically inside the hopper.

[0003] However, this traditional tray structure has many problems that need to be solved in practical applications. First, the vertically placed tray is significantly inconvenient during the positioning process. Because the tray needs to match the automated material handling requirements of the pick-and-place machine, its placement accuracy is required. However, the tray in a vertical position lacks a stable support reference, making the initial positioning operation cumbersome and requiring a lot of time for position calibration.

[0004] Secondly, to ensure the material tray can be smoothly placed into the positioning cavity, the size of the positioning cavity in existing material boxes is usually set to be slightly larger than the outer dimensions of the material tray. This results in a certain gap between the material tray and the positioning cavity. During the movement or transfer of the material box, the material tray is prone to swaying left and right within the positioning cavity due to external disturbances. This can cause the final position of the material tray to deviate, seriously affecting the precise positioning and material handling operations of the subsequent robotic arm, increasing the risk of failure and downtime for adjustment during the production process.

[0005] Furthermore, existing hopper designs only provide basic storage for the trays themselves, without providing a dedicated positioning structure for the tapes on the trays. As the direct carrier of electronic components, the positional stability of the tapes is crucial for the pick-and-place machine's accuracy. Due to the lack of effective positioning, the tapes are prone to shifting or slackening when the tray rotates or the hopper moves, further complicating subsequent automated operations and reducing the overall operating efficiency of the production line. Utility Model Content

[0006] The main purpose of this utility model is to propose a material box that aims to improve the positioning effect of the material tray and to position the material head of the material strip.

[0007] To achieve the above objectives, the present invention proposes a material box for storing electronic components, comprising a box body, multiple support components, multiple clamping modules, and a positioning component. At least some of the support components are arranged vertically at intervals within the box body, and the support components are used to horizontally support the material tray. The clamping modules are located one-to-one on one side of the support components in the horizontal direction, and the clamping modules are used to clamp the material strip on the material tray. The positioning component is installed on the support components and is used to position the material tray.

[0008] In one embodiment, each of the carrier components includes two carrier plates disposed opposite each other, the upper surfaces of which are used to place a material tray.

[0009] In one embodiment, the positioning component includes multiple positioning plate groups, each positioning plate group including two positioning plates disposed opposite to each other, and the two positioning plates are respectively disposed at the front end of the two support plates of each support component.

[0011] In one embodiment, the inner side of the positioning plate is formed with a curved surface adapted to the tray.

[0012] In one embodiment, the clamping module includes a fixing block, a cover plate, and a clamping block. One end of the fixing block is mounted on the housing. The cover plate is rotatably connected to the fixing block for clamping the material strip. The clamping block is rotatably connected to the fixing block for fastening the cover plate.

[0013] In one embodiment, the bin further includes at least one vertically arranged partition plate, which divides a portion of the bin body into at least two first spaces, and the load-bearing components are arranged vertically and horizontally in both first spaces.

[0014] In one embodiment, the first space is used to accommodate a tray of a first size, and the box further includes a second space, in which load-bearing components are spaced apart to accommodate trays of a second size, and the width of the second space is greater than the width of the first space.

[0015] In one embodiment, the housing further includes a third space, in which load-bearing components are spaced apart to accommodate a tray of a third size. The width of the third space is the same as the width of the second space, and the distance between two adjacent load-bearing components in the third space is greater than the distance between two adjacent load-bearing components in the second space.

[0016] In one embodiment, the first space, the second space, and the third space are arranged sequentially from top to bottom.

[0017] The technical solution of this utility model adopts a horizontal bearing tray design, which is easier to position and more compatible than the traditional vertically placed tray; and uses a clamping component to clamp the head of the material strip, which solves the problem of inconvenience in subsequent operations caused by the lack of positioning of the material strip in the traditional material box.

[0029] In a pick-and-place machine production line, the hopper is a key piece of equipment that holds the trays of electronic components. Currently, most hoppers on the market use a vertically spaced structure, with trays placed vertically layer by layer. This traditional structure has several drawbacks: First, vertically placed trays are difficult to position due to the lack of a stable support reference, requiring tedious initial calibration. Second, the positioning cavity is slightly larger than the tray, causing the tray to wobble easily when the hopper moves, affecting the robot's positioning and increasing the risk of malfunction. Third, the lack of a positioning structure for the conveyor belt makes it prone to misalignment and slack, exacerbating the difficulty of subsequent operations and reducing production efficiency.

[0030] Therefore, this utility model proposes a material box.

[0031] Please see Figures 1 to 4In one embodiment of this utility model, the material box is used to store a tray 50 of electronic components. The material box includes a box body 10, a plurality of supporting components 20, and a plurality of clamping components. At least some of the supporting components 20 are arranged vertically at intervals within the box body 10, and the supporting components 20 are used to horizontally support the tray 50. The clamping modules 30 are located one-to-one on one side of the supporting components 20 in the horizontal direction, and the clamping modules 30 are used to clamp the strip 51 on the tray 50.

[0032] Specifically, in this embodiment, the material bin is composed of a bin body 10, multiple load-bearing components 20, and multiple clamping components. The bin body 10, serving as the basic frame of the entire bin, is typically made of high-strength and lightweight materials. Its interior forms a semi-enclosed storage space, providing a stable mounting base for the load-bearing components 20 and clamping components, while also offering some protection to the material trays 50 stored inside. At least some of the load-bearing components 20 are arranged vertically within the bin body 10 at predetermined intervals. This arrangement allows for flexible adjustment of the spacing according to the size of the material trays 50 to accommodate different specifications. Each load-bearing component 20 has a stable horizontal load-bearing surface, enabling it to smoothly lift the material tray 50 horizontally. The clamping components are configured in a one-to-one correspondence with the load-bearing components 20. Each clamping component is precisely installed on one side of the corresponding load-bearing component 20 in the horizontal direction, tightly adhering to and clamping the material strip 51 on the material tray 50, achieving reliable positioning.

[0033] The one-to-one correspondence between the bearing component 20 and the clamping component is the core relationship. Each bearing component 20 has a dedicated clamping component fixedly installed on one side in the horizontal direction. The positions of the two are relatively fixed. When the material tray 50 is placed horizontally on the bearing component 20, the material strip 51 on the material tray 50 can just extend to the working area of ​​the corresponding clamping component, so that the clamping component can directly apply clamping force to the material strip 51.

[0034] The support component 20 adopts a horizontal support tray 50 design, which has significant advantages compared to the vertical placement of the tray 50 in traditional material bins. The horizontal orientation provides a large and stable support reference for the tray 50. Initial positioning of the tray 50 only requires alignment with the positioning edge of the support component 20, greatly simplifying the positioning process, reducing manual calibration steps during initial positioning, and improving the loading efficiency of the tray 50. In the horizontal support state, the rotation of the tray is not significantly affected by automatic thickness or winding layer count, and its compatibility is greatly improved.

[0035] The one-to-one correspondence between the clamping components and the carrier components 20 enables precise clamping and positioning of the head position of the strip 51 on each tray 50. The clamping force can be adjusted according to the material and thickness of the strip 51, ensuring that the strip 51 does not shift or loosen, while also avoiding damage caused by over-clamping. This effectively solves the problem of inconvenience in subsequent operations caused by the lack of positioning of the strip 51 in traditional material boxes. Furthermore, the vertically spaced arrangement of the carrier components 20 allows for the orderly storage of multiple trays 50 and full utilization of the space in the box 10. Combined with the stability provided by horizontal support and the reliability of the strip 51 clamping and positioning, the trays 50 do not wobble left and right during material box movement, unlike when placed vertically in the traditional way, effectively ensuring their positional accuracy. This lays a solid foundation for the subsequent precise positioning and material handling operations of the robotic arm, reducing production failures caused by inaccurate positioning, thereby significantly improving the overall operating efficiency of the pick-and-place machine production line and reducing production costs and failure risks.

[0036] Furthermore, each carrier component 20 includes two carrier plates 21 arranged opposite to each other, and the upper surface of the two carrier plates 21 is used to place the tray 50.

[0037] Specifically, in this embodiment, each support component 20 includes two oppositely arranged support plates 21, which are symmetrically distributed and their spacing can be adjusted according to the diameter or width of the tray 50. The upper surfaces of the two support plates 21 together form a support surface for placing the tray 50, and the upper surfaces are kept at the same horizontal height. The surfaces are smooth and have a certain friction, which can stably support the tray 50.

[0038] The two support plates 21, as components of the support assembly 20, cooperate to form a support structure for the material tray 50. Their relative positional relationship ensures that the material tray 50 is effectively supported on both sides when placed, preventing the material tray 50 from tilting due to unilateral force. At the same time, the support plates 21 are stably connected to the support assembly 20 as a whole and the housing 10, and their positions match the working areas of the corresponding clamping components. When the material tray 50 is placed on the upper surfaces of the two support plates 21, the material strip 51 can extend smoothly to the clamping components.

[0039] Compared to a single solid support surface, two opposing support plates 21 can significantly reduce the amount of raw materials required for manufacturing. While ensuring effective support for the tray 50, the material in the non-supported area below the tray 50 is eliminated, reducing the overall weight of the tray and also reducing material costs and processing time during production, meeting the design requirements of lightweighting and economy; at the same time, the non-supported area below the tray 50 also facilitates the passage of a robotic arm to remove the tray 50.

[0040] Furthermore, the hopper also includes a positioning component 40 installed on the support component 20, which is used to position the tray 50.

[0041] Specifically, in this embodiment, the newly added positioning component 40 of the material box is installed on the support plate 21 of the support component 20. The support plate 21 can be precisely adapted to the edge of the material tray 50 or the preset positioning part, and is specifically used to limit the position of the material tray 50 placed on the support plate 21. The positioning component 40 and the support plate 21 form a fixed installation relationship, and together with the support plate 21, they constitute a part of the support component 20.

[0042] Furthermore, the positioning component 40 includes multiple positioning plate groups 41, each positioning plate group 41 including two positioning plates 411 arranged opposite to each other, and the two positioning plates 411 are respectively disposed at the front end of the two support plates 21 of each support component 20.

[0043] In this embodiment, the positioning component 40 is composed of multiple positioning plate groups 41. Each positioning plate group 41 includes two opposing positioning plates 411, which are respectively installed at the front ends of the two support plates 21 of each support component 20. The positioning plates 411 have a certain height, and their inner edges can be adapted to the outer periphery of the material tray 50 to form a limiting structure.

[0044] The positioning plate group 41 corresponds one-to-one with the support component 20. Each of the two support plates 21 of each support component 20 is equipped with a positioning plate 411 at its front end, forming a positioning plate group 41 together. The two work together to form a positioning space for the front end of the material tray 50. The positioning plate 411 is firmly connected to the support plate 21 and its position is precise, ensuring that when the material tray 50 is placed on the support plate 21, it can be held in place by the two opposing positioning plates 411 from both sides.

[0045] The arrangement of multiple positioning plate groups 41 further enhances the accuracy and stability of positioning each tray 50. Two positioning plates 411 in each positioning plate group 41 form a limiting position from both sides of the front end of the tray 50. This not only makes the initial placement of the tray 50 more convenient, eliminating the need for repeated adjustments, but also further restricts the wobbling of the tray 50 during the movement of the material box. This provides a more reliable positional reference for the subsequent precise grasping of electronic components by the robotic arm, reducing production errors caused by tray 50 displacement and improving the stability and efficiency of the production line. Simultaneously, the positioning plate group 41 has a simple structure, is easy to install and adapt to trays 50 of different sizes, enhancing the practicality of the material box.

[0046] Furthermore, the positioning component 40 also includes two positioning posts 42, both of which are vertically arranged at the rear end of the two support plates 21, and the feeding tray 50 is placed between the two positioning posts 42 and the two positioning plates 411 of each support component 20.

[0047] Specifically, in this embodiment, the two positioning posts 42 and the two positioning plates 411 of the same supporting component 20 form a front-to-back layout. The positioning posts 42 are installed at the rear end of the supporting plate 21, forming a certain distance in the horizontal direction with the front positioning plate group 41. This distance is exactly adapted to the length or diameter of the tray 50, so that the tray 50 can be accurately placed between the two positioning posts 42 and the positioning plate group 41. At the same time, the positioning posts 42 are firmly connected to the supporting plate 21, and their positions correspond to the positioning plate group 41, together forming an enclosing positioning structure for the tray 50.

[0048] The addition of two positioning posts 42 further improves the positioning system of the tray 50. The front positioning plate assembly 41 limits the front end of the tray 50 from both sides, while the two positioning posts 42 at the rear end form a barrier from the rear end of the tray 50. The front and rear work together to form a closed-loop constraint, which can effectively prevent the tray 50 from moving in the front-to-back direction and greatly improve the positioning stability of the tray 50 in the horizontal direction. Even if the tray is subjected to large bumps during movement, the tray 50 can remain in the preset position, avoiding deviations in the robot arm's material handling caused by displacement. In addition, this front-to-back coordinated positioning structure makes the placement of the tray 50 more convenient and efficient. The operator only needs to align the rear end of the tray 50 with the positioning post 42 and the front end with the positioning plate assembly 41 to complete the precise positioning, reducing adjustment time. At the same time, the positioning post 42 has a simple structure and low manufacturing cost. When used with the positioning plate assembly 41, it can be adapted to various specifications of trays 50, further enhancing the versatility and practicality of the tray and providing a more reliable guarantee for the efficient operation of the pick-and-place machine production line.

[0049] Furthermore, the inner side of the positioning plate 411 is formed with a curved surface that is adapted to the material tray 50.

[0050] Specifically, the curved surface on the inner side of the positioning plate 411 is the key structure for the positioning plate assembly 41 to position the circular tray 50, and it is integrated with the overall structure of the positioning plate 411. When the tray 50 is placed between the two positioning posts 42 and the positioning plate assembly 41, the curved surface can precisely fit the outer contour of the circular tray 50. Combined with the positioning posts 42 limiting the tray from the rear, it forms a more stable constraint on the tray 50. Moreover, this structure does not affect the connection between the positioning plate 411 and the bearing plate 21, or the cooperation relationship between the positioning plate assembly 41 and other components.

[0051] The curved surface of the positioning plate 411, which matches the outer contour of the circular tray 50, greatly improves the positioning accuracy and fit of the positioning plate assembly 41 to the tray 50. Compared to the flat positioning plate 411, the curved surface can form a larger contact area with the circular tray 50, enhancing the limiting effect on the tray 50 and effectively preventing the tray 50 from rotating or shifting in the left and right directions. Simultaneously, the precise matching of the curved surface with the outer contour of the tray 50 allows the tray 50 to find its accurate position more quickly during placement, further simplifying the operation process. Furthermore, this fitted positioning reduces wear between the positioning plate 411 and the tray 50, extending the service life of both the tray 50 and the positioning plate 411, providing more favorable conditions for the stable operation of the pick-and-place machine production line.

[0052] Furthermore, the clamping module 30 includes a fixing block 31, a cover plate 32, and a clamping block 33. One end of the fixing block 31 is installed on the housing 10; the cover plate 32 is rotatably connected to the fixing block 31 for clamping the material strip 51; and the clamping block 33 is rotatably connected to the fixing block 31 for fastening the cover plate 32.

[0053] Specifically, in this embodiment, the clamping module 30 consists of a fixing block 31, a cover plate 32, and a clamping block 33. One end of the fixing block 31 is connected to the housing 10, serving as the mounting base for the entire clamping module 30 and possessing stable structural strength. The cover plate 32 is rotatably connected to the fixing block 31 and can rotate around the connection point. Its rotation trajectory covers the placement area of ​​the material strip 51, thereby clamping the material strip 51. The clamping block 33 is also rotatably connected to the fixing block 31, and during rotation, it can form a snap-fit ​​relationship with the cover plate 32, thus fixing the cover plate 32 at the position where the material strip 51 is clamped.

[0054] The fixing block 31 serves as the mounting carrier for the cover plate 32 and the clamping block 33. Both the cover plate 32 and the clamping block 33 rotate with the fixing block 31 as a reference. When it is necessary to clamp the material strip 51, the cover plate 32 rotates to a position that fits the material strip 51, and then the clamping block 33 rotates and latches onto the cover plate 32. The three components work together to clamp and position the material strip 51. This connection ensures the coordination of the movements of the cover plate 32 and the clamping block 33, and the rotation range of each component is designed to prevent interference with other components such as the bearing assembly 20 and the positioning assembly 40.

[0055] The fixing block 31 has two spaced lugs 311 on its end face, and also has a positioning groove 312 adapted to the material strip 51. The shape and size of the positioning groove 312 can fit the shape of the material strip 51, providing initial placement and positioning for the material strip 51. One end of the cover plate 32 is rotatably connected to the lugs 311 via a first rotating shaft 34, and can rotate flexibly around the first rotating shaft 34. After rotation, the other end can cover the material strip 51 in the positioning groove 312, achieving coverage and constraint of the material strip 51. The fixing block 31 has a receiving groove 313 on the side away from the first rotating shaft 34. The clamping block 33 is rotatably installed in the receiving groove 313 via a second rotating shaft 35. One end of the clamping block 33 has a fastening part 331, and the other end is connected to a first spring 36. The elastic force of the first spring 36 causes the fastening part 331 to fasten the cover plate 32. A second spring 37 is provided on the first rotating shaft 34. When the clamping block 33 is released, the second spring 37 springs the cover plate 32 open.

[0056] Lug 311 provides a support point for the rotation of cover plate 32. When cover plate 32 rotates, its other end engages with positioning groove 312 to form a wrapping fixation for material strip 51. Receiving groove 313 provides installation space for clamping block 33 and first spring 36. Second rotating shaft 35 ensures stable rotation of clamping block 33. The elastic force of first spring 36 acts on the end of clamping block 33 away from fastening part 331, causing fastening part 331 to be tightly fastened to cover plate 32, forming a lock on cover plate 32, thereby allowing cover plate 32 to continuously press material strip 51 into positioning groove 312. All components cooperate with each other to form a complete material strip 51 fixing system from positioning, clamping to locking, and the connection with fixing block 31 is stable and will not affect the overall working stability of clamping module 30.

[0057] The positioning groove 312 on the fixing block 31 can pre-position the strip 51, reducing positional deviation when the strip 51 is placed. The cooperation between the lug 311 and the first rotating shaft 34 allows the cover plate 32 to rotate smoothly. The cover plate 32 covers the strip 51 in the positioning groove 312, preventing the strip 51 from moving up and down. Under the action of the first spring 36, the clamping block 33 in the receiving groove 313 firmly locks the cover plate 32 through the fastening part 331, ensuring that the clamping force of the cover plate 32 on the strip 51 is stable. Even if the material box shakes, the strip 51 will not loosen or shift. This structural design not only improves the accuracy and stability of the strip 51 positioning, but also makes the installation and removal of the strip 51 more convenient. Simply overcome the elastic force of the first spring 36 and rotate the clamping block 33 to loosen or lock the cover plate 32, effectively improving work efficiency and providing a reliable guarantee for the subsequent material handling by the robot. The second spring 37 provided on the first rotating shaft 34 is used to provide elastic force to the cover plate 32, so that the cover plate 32 springs open when the clamping block 33 is disengaged from the cover plate 32.

[0058] Furthermore, the bin also includes at least one vertically arranged partition plate 11, which divides a portion of the bin body 10 into at least two first spaces 12, and each of the two first spaces 12 is provided with a load-bearing component 20 spaced vertically.

[0059] Specifically, the hopper includes at least one vertically arranged partition plate 11. The partition plate 11 is made of a rigid material and has a certain thickness and height, enabling it to be stably installed inside the hopper body 10. It divides a portion of the space inside the hopper body 10 into at least two independent first spaces 12. The dimensions of each first space 12 are designed according to actual needs and can accommodate the corresponding support components 20 and the material tray 50. Support components 20 are arranged vertically and at intervals within both first spaces 12, and the arrangement of the support components 20 is consistent with the previous description.

[0060] The partition plate 11 is firmly connected to the inner wall of the box 10, and is secured by welding, bolts, or other methods to ensure it will not shake during use. The separated first spaces 12 are adapted to the load-bearing components 20, and the load-bearing components 20 in each first space 12 are arranged independently without interfering with each other. This partition structure allows trays 50 of the same specification to be placed in different first spaces 12, facilitating classified management.

[0061] The vertical partition 11 enables a rational division of the space within the housing 10, dividing a portion of the housing 10 into multiple first spaces 12. This allows for the categorized storage of trays 50 of the same size, preventing mixing and facilitating quick identification and retrieval by operators. Simultaneously, each first space 12 has an independently installed support component 20, reducing mutual interference between different trays 50 and further enhancing the orderliness of the internal structure of the housing. Furthermore, this design increases the storage capacity of the housing, accommodating more trays 50 within the limited space of the housing 10, improving space utilization, and better meeting the supply needs of various electronic components in the pick-and-place machine production line.

[0062] It should be noted that, as Figure 1 As shown, there are two first spaces 12, one on the left and one on the right. In this embodiment, the spacing between two adjacent vertically aligned support components 20 in the left and right columns is consistent, used to store trays of the same specification. In some embodiments, trays of different widths can be stored in the left and right first spaces 12; for example, the distance between two adjacent vertically aligned support components 20 in the right first space 12 is greater than the distance between two adjacent vertically aligned support components 20 in the left first space 12. In other embodiments, trays of different widths can also be stored in the first spaces 12 of the same column; for example, the distance between two adjacent lower support components 20 is greater than the distance between two adjacent upper support components 20.

[0063] Furthermore, the first space 12 is used to accommodate a tray 50 of the first size, and the box 10 also includes a second space 13, in which a support component 20 is spaced apart to accommodate a tray 50 of the second size, and the width of the second space 13 is greater than the width of the first space 12.

[0064] Specifically, the first space 12 is specifically designed to accommodate a tray 50 of a first size, and the supporting components 20 arranged vertically inside the first space are adapted to the tray 50 of that size. The housing 10 is also provided with a second space 13, which is also arranged with supporting components 20 at intervals inside. These supporting components 20 are used to accommodate a tray 50 of a second size, and the width of the second space 13 is greater than the width of the first space 12, so as to accommodate a larger size tray 50.

[0065] The first space 12 and the second space 13 are both internal spaces of the housing 10, but they are independent of each other. The specifications of the load-bearing components 20 in the first space 12 are matched with the specifications of the first-sized tray 50, while the specifications of the load-bearing components 20 in the second space 13 correspond to the specifications of the second-sized tray 50. Furthermore, because the second space 13 is wider, the spacing and other settings of its load-bearing components 20 are different from those in the first space 12. This division allows trays 50 of different sizes to be placed appropriately, making the spatial layout more targeted.

[0066] The separate design of the first space 12 and the second space 13 enables precise accommodation of trays 50 of different sizes, avoiding instability caused by mismatched spaces. The second space 13 is wider than the first space 12, meeting the storage requirements of trays 50 of different sizes and expanding the applicability of the material box. Simultaneously, the separate placement of trays 50 of different sizes further improves the internal organization of the material box, allowing operators to quickly locate the corresponding storage area based on the size of the tray 50, improving the efficiency of tray loading, unloading, and management, and better adapting to the supply needs of the pick-and-place machine production line for various specifications of electronic components.

[0067] Furthermore, the housing 10 also includes a third space 14, in which load-bearing components 20 are spaced apart to accommodate a third-sized tray 50. The width of the third space 14 is the same as the width of the second space 13, and the distance between two adjacent load-bearing components 20 in the third space 14 is greater than the distance between two adjacent load-bearing components 20 in the second space 13.

[0068] Specifically, the housing 10 also includes a third space 14, in which spaced-apart support components 20 are used to accommodate a third-sized tray 50. The width of the third space 14 is the same as that of the second space 13, but the distance between two adjacent vertical support components 20 inside the third space 14 is greater than the distance between two adjacent vertical support components 20 inside the second space 13, in order to accommodate the height requirements of the third-sized tray 50.

[0069] The third space 14, along with the first space 12 and the second space 13, is an independent space within the housing 10. The third space 14 has the same width as the second space 13, and in the horizontal width direction, it can accommodate a third-sized tray 50 with a width similar to the second-sized tray 50. However, the vertical spacing of the supporting components 20 in the two spaces differs, indicating a targeted adaptation for trays 50 of different heights. The supporting components 20 in the three spaces are respectively matched with trays 50 of corresponding sizes, forming a classification and accommodation system for trays 50 of various specifications.

[0070] The third space 14 further enhances the hopper's compatibility with trays 50 of different sizes. While having the same width as the second space 13, it features a larger vertical spacing between the load-bearing components 20, accommodating trays 50 of similar width but greater height. This avoids the problem of trays 50 being unable to be placed or being unstable due to insufficient height. This allows the hopper to accommodate a wider variety of tray sizes, significantly improving its versatility and flexibility. Simultaneously, the clear division of the three spaces allows for more detailed classification and storage of trays 50 of different sizes. Operators can quickly locate the corresponding storage space based on the specific dimensions of the tray 50, further improving the efficiency of tray management and loading / unloading, and better meeting the diverse electronic component supply needs of the pick-and-place machine production line.

[0071] In this embodiment, the first space, second space, and third space are arranged sequentially from top to bottom. The first space has the longest vertical length, while the second and third spaces are shorter than the first space in the vertical direction. The specific dimensions can be set according to actual needs, such as based on the size of commonly used material strips. Since the first-size material strip is more frequently used, the first space is set to have the longest length to accommodate more first-size material strips. It should be noted that other layouts of the first, second, and third spaces can also be used. For example, from top to bottom, they could be third space, second space, first space; or first space, third space, second space, etc. The specific layout is set according to actual needs.

[0072] The first size is a 7-inch 8mm tray, the second size is a 13-inch 8mm tray, and the third size is a 13-inch 8-24mm tray. Understandably, in some embodiments, more partitions can be installed inside the housing to create more space and accommodate trays of various sizes.

[0073] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
