Description

TECHNICAL FIELD

[0001] The utility model relates to PCB processing technical field especially relates to a conveying device, feeding and discharging system and PCB processing equipment. BACKGROUND

[0002] In order to fix multiple PCB (Printed Circuit Board, printed circuit board) and other materials, positioning pins are usually used to pass through multiple materials stacked together to connect the materials together. When the pre-fixed materials are transferred to the processing table, the materials can be placed in the stock bin, and the materials can be transferred by transferring the stock bin.

[0003] The stock bin has a material frame, a support plate and a guide plate. The support plate and the guide plate are arranged on the material frame. The support plate is used to place the materials. The guide plate is provided with a guide groove. When the materials are placed on the support plate, the materials are located between the support plate and the guide plate, and the positioning pins on the materials are located in the guide groove.

[0004] When the materials are placed in the stock bin, the materials can be pushed onto the support plate along the length direction of the guide groove. During this process, the materials can be guided by the guide groove. When the materials are removed from the stock bin, the materials can be pushed out of the stock bin along the length direction of the guide groove. During this process, the materials can also be guided by the guide groove.

[0056] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0057] In the description of this utility model, it should be understood that the terms "longitudinal", "radial", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0058] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0059] like Figures 1 to 5 As shown, in one embodiment, the conveying device 10 includes a support module 1, a storage module 2, and a drive module 3; the storage module 2 includes a hopper 21 and a guide plate 22; the hopper 21 is disposed on the support module 1 and is used to place materials; the guide plate 22 is movably connected to the hopper 21 and can reciprocate relative to the hopper 21 in a first direction; the drive module 3 is connected to the support module 1 and can drive the guide plate 22 to reciprocate in the first direction so that the guide plate 22 moves into or out of the hopper 21.

[0060] Among them, Figure 1 Of the directions shown, the first direction is parallel to the X-axis.

[0061] Initially, the guide plate 22 is located inside the hopper 21. When it is necessary to move the material in the hopper 21 to the target station of the target device (the target station can be a material placement platform, etc., which may be part of the buffer device or host described below), the hopper 21 is first moved to a suitable position. At this time, the guide plate 22 is a certain distance away from the target station. Then, the drive module 3 drives the guide plate 22 to move along the first direction, so that the guide plate 22 moves out of the hopper 21 and closer to the target station, thereby reducing the distance between the guide plate 22 and the target station. Then, the material in the hopper 21 is driven to move along the first direction, so that it moves closer to and to the target station. During this process, the guide plate 22 can guide the material.

[0062] By driving the guide plate 22 closer to the target station to reduce the distance between them, the guide plate 22 can stably guide the movement of the material during its movement from the hopper 21 to the target station, thus effectively preventing the material from deviating from its loading position. Specifically, when the distance between the guide plate 22 and the target station is zero, the material is always guided and limited by the guide structure 221 during its movement from the hopper 21 to the target station.

[0063] In one embodiment, the drive module 3 can drive the material to move along a first direction, so that the material is removed from the hopper 21. Specifically, the drive module 3 can independently drive the guide plate 22 to reciprocate along the first direction. During this process, the drive module 3 does not apply force to the material, allowing the material to remain within the hopper 21. Furthermore, the drive module 3 can also independently drive the material within the hopper 21 to reciprocate along the first direction. During this process, the drive module 3 does not apply force to the guide plate 22, allowing the guide plate 22 to remain in its current position.

[0064] In addition, the guide plate is provided with a guide structure 221, which is used to cooperate with the positioning element on the material to guide the movement of the material along the first direction.

[0065] Furthermore, the material can be a PCB, and the positioning element can be a pin set on the PCB. In practical scenarios, the material may consist of multiple PCBs stacked together and secured together by pins. Moreover, the pins protrude from at least one of the outermost PCBs to engage with the guiding structure.

[0066] like Figure 2As shown, in one embodiment, the support module 1 includes a support component 11, a lifting drive component 12, and a lifting platform 13; the lifting drive component 12 connects the support component 11 and the lifting platform 13; the hopper 21 is placed on the lifting platform 13; the lifting drive component 12 can drive the lifting platform 13 to reciprocate along a second direction to adjust the position of the hopper 21 in the second direction; the second direction intersects with the first direction. The second direction is parallel to the Z-axis and can also be perpendicular to the first direction. Furthermore, the second direction can be a vertical direction.

[0067] When the height of the hopper 21 (i.e., its position in the second direction) is adjusted, the height of the guide plate 22 on the hopper 21 and the material will also be adjusted, so that the guide plate 22 can connect to the target workstations at different heights, thereby improving the adaptability of the conveying device 10.

[0068] In one embodiment, the drive module 3 is connected to the support component 11 and is spaced apart from the lifting platform 13 in the second direction; moreover, the drive module 3, the support component 11 and the lifting drive component 12 are located on the same side of the lifting platform 13; in addition, in operation, in the second direction, the hopper 21 is placed on the side of the lifting platform 13 closer to the drive module 3.

[0069] The drive module 3 is located above the lifting platform 13, and the hopper 21 can be placed on the upper surface of the lifting platform 13.

[0070] like Figure 2 As shown, in one embodiment, the support assembly 11 and the lifting platform 13 are spaced apart in a third direction, wherein both the first direction and the second direction intersect the third direction. Furthermore, the third direction is perpendicular to the first direction and also perpendicular to the second direction. Figure 1 Of the directions shown, the third direction is parallel to the Y-axis.

[0071] In one embodiment, the support component 11 is generally in the form of a cuboid structure. Of course, the support component 11 can also be set in other shapes.

[0072] In one embodiment, on the third-side, the support component 11 has a receiving groove 111 on the surface near the lifting platform 13, and the lifting drive component 12 is disposed on the bottom surface of the receiving groove 111. This arrangement can protect the lifting drive component 12 through the groove wall of the receiving groove 111, effectively preventing the lifting drive component 12 from being hit by external objects.

[0073] In one embodiment, the lifting drive assembly 12 includes a rotary motor, a lead screw drive mechanism, and a guide mechanism. The rotary motor is connected to the lead screw of the lead screw drive mechanism, and the nut of the lead screw drive mechanism is connected to the lifting platform 13. When the rotary motor drives the lead screw to rotate, it can drive the nut to move up and down, thereby driving the lifting platform 13 to move up and down. The guide mechanism connects the support assembly 11 and the lifting platform 13 and is used to guide the movement of the lifting platform 13 in the second direction. It should be understood that the lead screw drive mechanism can also be replaced by a gear and rack drive mechanism, a chain drive mechanism, or a belt drive mechanism, etc. Of course, the combination of the rotary motor and the lead screw drive mechanism can also be replaced by a linear motor, etc.

[0074] like Figure 2 As shown, in one embodiment, the lifting platform 13 is provided with a weight reduction hole 131 to reduce the weight of the lifting platform 13.

[0075] The weight-reducing holes 131 can be provided on the upper surface of the lifting platform 13 and can penetrate the lifting platform 13. Moreover, there can be multiple weight-reducing holes 131, which are spaced apart from each other. This can further reduce the weight of the lifting platform 13 while ensuring the supporting effect of the lifting platform 13 on the hopper 21.

[0076] "Multiple" means two or more. The meaning of the word "multiple" is the same in all embodiments and will not be repeated hereafter.

[0077] like Figure 2 As shown, in one embodiment, the lifting platform 13 is provided with a first positioning member 14, and the hopper 21 is provided with a second positioning member 23; the first positioning member 14 can cooperate with the second positioning member 23 to limit the placement position of the hopper 21 on the lifting platform 13. This arrangement can make the hopper 21 more accurately placed on the lifting platform 13, which is beneficial to improving the accuracy of the guide plate 22 docking with the target station.

[0078] In one embodiment, the first positioning member 14 is a positioning post, and the second positioning member 23 is provided with a positioning hole. When the hopper 21 is placed on the lifting platform 13, the positioning post can be inserted into the positioning hole to achieve positioning of the hopper 21.

[0079] Furthermore, the hopper 21 placed on the lifting platform 13 is actually placed on the upper surface of the lifting platform 13. The first positioning member 14 protrudes from the lifting platform 13 in a bottom-to-top direction.

[0080] like Figure 3As shown, in one embodiment, the first positioning member 14 includes a guide portion 141 and a positioning portion 142 connected sequentially from top to bottom. The guide portion 141 gradually increases in size from top to bottom to facilitate the entry of the positioning pin into the positioning hole. The positioning portion 142 is used to engage with the positioning hole to position the hopper 21.

[0081] The guide portion 141 has a circular cross-section, which can be a frustum or a cone structure. The positioning portion 142 has a cylindrical structure. The guide portion 141 and the positioning portion 142 are coaxially arranged, and the maximum diameter of the guide portion 141 can be equal to the diameter of the positioning portion 142. Moreover, the guide portion 141 is the top end of the positioning member.

[0082] In one embodiment, the number of first positioning members 14 can be one or more. Additionally, in a third-party orientation, the first positioning member 14 can be located between the lifting platform 13 and the support component.

[0083] like Figure 2 and Figure 4 As shown, in one embodiment, a limiting plate 15 is provided on the lifting platform 13, which also limits the placement position of the hopper 21 on the lifting platform 13. The limiting plate 15 facilitates the cooperation between the first positioning member 14 and the second positioning member 23.

[0084] In one embodiment, the hopper 21 can be placed on the lifting platform 13 in a top-to-bottom direction. In this case, the limiting plate 15 can guide and limit the hopper 21 moving in a top-to-bottom direction, thereby placing it in a suitable position on the lifting platform 13.

[0085] like Figure 2 As shown, in the third direction, the limiting plate 15 is disposed on the side of the lifting platform 13 away from the support assembly 11, for guiding the hopper 21 toward the support assembly 11. The limiting plate 15 has a guide surface 151 on the side near the lifting assembly (see reference). Figure 4 Along a top-to-bottom direction, the guide surface 151 gradually approaches the support component 11, and the guide surface 151 may extend upward to intersect with the top surface of the limiting plate 15. In addition, the guide surface 151 may be a flat surface or an arc-shaped surface, etc.

[0086] In one embodiment, there are multiple limiting plates 15. In the third direction, each limiting plate 15 is located on the side of the lifting platform 13 opposite to the support assembly 11. In addition, the limiting plates 15 are spaced apart along the first direction.

[0087] like Figure 2As shown, in one embodiment, the drive module 3 includes a first drive component 31, a second drive component 32, and a pusher 33. The first drive component 31 drives the pusher 33 to reciprocate along a second direction, aligning the pusher 33 with the guide plate 22 or the material placed in the hopper 21. The second drive component 32 drives the pusher 33 to reciprocate along a first direction, pushing the guide plate 22 or the material aligned with it to move along the first direction. In this embodiment, the material in the hopper 21 is pushed to the target station by the pusher 33, which facilitates the application of force to the material, simplifies the structure of the drive module 3, facilitates the production and assembly of the drive module 3, and reduces costs.

[0088] When the pusher 33 is aligned with the guide plate 22, if the pusher 33 is driven to move in the first direction, the pusher 33 can abut against the guide plate 22 and push the guide plate 22 to move in the first direction. When the pusher 33 is aligned with the material, if the pusher 33 is driven to move in the first direction, the pusher 33 can abut against the material and push the guide plate 22 to move in the first direction.

[0089] Specifically, when the pusher 33 is aligned with the guide plate 22, in an orthographic projection on a plane perpendicular to the first direction, the projection of the pusher 33 and the projection of the guide plate 22 aligned with it overlap by at least a portion.

[0090] When the pusher 33 is aligned with the material, in an orthographic projection on a plane perpendicular to the first direction, the projection of the pusher 33 and the projection of the material it is aligned with overlap at least partially.

[0091] In addition, the structure of either the first drive component 31 or the second drive component 32 can be the same as the structure of the lifting drive component 12 described above.

[0092] In one embodiment, the first drive component 31 may be connected to the support module 1 (specifically, it may be connected to the support component 11), the second drive component 32 may be connected to the first drive component 31, and the pusher 33 may be connected to the second drive component 32. That is, the second drive component 32 is connected to the support component 11 through the first drive component 31, and the pusher 33 is connected to the first drive component 31 through the second drive component 32. In this embodiment, the drive module 3 is mounted on the support module 1, thus eliminating the need for a cantilever structure on the hopper 21 to mount the drive module 3, thereby significantly reducing the probability of deformation of the hopper 21 and avoiding friction between the hopper 21 and the pusher 33, etc., due to deformation. Of course, in other embodiments, the first drive component 31 may also be connected to the support module 1 (specifically, it may be connected to the support component 11) through the second drive component 32. In this case, the second drive component 32 may be connected to the support component 11, the first drive component 31 may be connected to the second drive component 32, and the pusher 33 may be connected to the first drive component 31.

[0093] In one embodiment, the pusher 33 can be a rod-shaped object, which can be a cuboid structure or a cylindrical structure, etc. Of course, the pusher 33 can also be other shapes, and this embodiment does not impose any restrictions on it.

[0094] like Figure 2 As shown, in one embodiment, the drive module 3 further includes a third drive component 34, which drives the pusher 33 to rotate around a first axis, enabling the pusher 33 to move into or out of the hopper 21; wherein the first axis is parallel to the second direction. When the hopper 21 is placed on the support module 1, the third drive component 34 can drive the pusher 33 to rotate, thereby causing the pusher 33 to be misaligned with the hopper 21 and avoiding interference between them; after the hopper 21 is placed on the support module 1, the third drive component 34 can drive the pusher 33 to rotate, thereby causing the pusher 33 to extend into the hopper 21 to push the guide plate 22 and the material.

[0095] The third drive component 34 may include a rotary motor or a rotary cylinder, etc., to drive the pusher 33 to rotate around the first axis.

[0096] Furthermore, when the second drive assembly 32 is connected to the support assembly 11 via the first drive assembly 31, the third drive assembly 34 is connected to the second drive assembly 32, and the pusher 33 is connected to the third drive assembly 34; that is, the pusher 33 is connected to the second drive assembly 32 via the third drive assembly 34. Conversely, when the first drive assembly 31 is connected to the support assembly 11 via the second drive assembly 32, the third drive assembly 34 is connected to the first drive assembly 31, and the pusher 33 is connected to the third drive assembly 34; that is, the pusher 33 is connected to the first drive assembly 31 via the third drive assembly 34.

[0097] Additionally, the third drive assembly 34 can be connected to one end of the pusher 33. When the third drive assembly 34 drives the pusher 33 to rotate forward around the first axis, the other end of the pusher 33 can rotate into the hopper 21. At this time, driving the pusher 33 to move in the first direction allows the pusher 33 to push the guide plate 22 or the material to move in the first direction. When the third drive assembly 34 drives the pusher 33 to rotate in the opposite direction around the first axis, the other end of the pusher 33 can rotate out of the hopper 21. At this time, the pusher 33 is misaligned with the hopper 21 placed on the lifting platform 13, and driving the pusher 33 to move in the first direction prevents the pusher 33 from colliding or interfering with the hopper 21.

[0098] In one embodiment, a rotating wheel is connected to the end of the pusher 33 away from the third drive assembly 34 (i.e., the other end of the pusher 33). The rotating wheel can rotate relative to the pusher 33 about its own axis, wherein the axis of the rotating wheel can be parallel to the first axis. In addition, at least one side of the rotating wheel can protrude from the pusher 33 in the circumferential direction of the rotation of the pusher 33 about the first axis. In actual operation, when the pusher 33 rotates about the first axis, its end away from the third drive assembly 34 may collide with or abut against other objects (such as materials or guide plate 22). In this embodiment, by setting the rotating wheel, the end of the pusher 33 away from the third drive assembly 34 can be prevented from directly contacting the other object. At this time, the rotating wheel abuts against the other object. Since the rotating wheel can rotate about its own axis, when the rotating wheel abuts against the other object, if the pusher 33 continues to rotate about the first axis, the rotating wheel will rotate relative to the pusher 33 and the object it abuts against, thereby reducing the frictional force on the object it abuts against.

[0099] In one embodiment, the wheel may also be a protruding rolling element 224 in the direction from the end of the pusher 33 connected to the third drive component 34 to the end of the pusher 33 away from the third drive component 34.

[0100] In one embodiment, a first driving component 31 is connected to a second driving component 32, a third driving component 34 is connected to the second driving component 32, and a pusher 33 is connected to the third driving component 34; the first driving component 31 can drive the second driving component 32, the third driving component 34, and the pusher to move synchronously in a second direction; the second driving component 32 can drive the third driving component 34 and the pusher to move synchronously in a first direction.

[0101] In one embodiment, multiple third drive components 34 and pushers 33 are provided; each third drive component 34 is spaced apart along a first direction; the third drive components 34 and pushers 33 are correspondingly connected; the third drive component 34 is used to drive its corresponding pusher 33 to rotate around a first axis. Figure 2 In the example shown, there are two of each of the third drive component 34 and the pusher 33.

[0102] During operation, the material or guide plate 22 can be pushed sequentially by each pusher 33, which can reduce the maximum drive stroke of the second drive assembly 32 and facilitate the miniaturization design of the drive module 3.

[0103] Taking two third drive components 34 and two pushers 33 as an example, these two pushers 33 are defined as the first pusher 33 and the second pusher 33, respectively. During operation, the first pusher 33 and the second pusher 33 can be driven to move to the initial position in the first direction, at which point both are outside the hopper 21. Then, the first pusher 33 is driven to rotate into the hopper 21 to align with the material. Then, the first pusher 33 is driven to move along the first direction so that the material is pushed along the first direction by the first pusher 33, and the distance of the material movement is greater than or equal to the distance between the first pusher 33 and the second pusher 33 in the first direction. Then, the first pusher 33 and the second pusher 33 are driven to move to the initial position in the first direction again. Then, the first pusher 33 is driven to rotate the discharge hopper 21, and the second pusher 33 is driven to rotate into the hopper 21 to align with the material. Then, the second pusher 33 is driven to move along the first direction so that the material is continued to be pushed along the first direction by the second pusher 33.

[0104] Alternatively, when there are two third drive components 34 and two pushers 33, one pusher 33 can be used to push the guide plate 22 out of the hopper 21, and the other pusher 33 can be used to push the guide plate 22 into the hopper 21.

[0105] In other embodiments, the number of the third drive component 34 and the pusher 33 may both be one. In this case, the pusher 33 is used both to push the guide plate 22 out of the hopper 21 and to push the guide plate 22 into the hopper 21.

[0106] As shown in the figureFigures 5 to 7 As shown, in one embodiment, the hopper 21 includes a first material frame 211, a second material frame 212, a material frame connector 213, and a support plate 214. In a third direction, the first material frame 211 and the second material frame 212 are spaced apart. The material frame connector 213 connects the first material frame 211 and the second material frame 212. The support plate 214 and the guide plate 22 are both located between the first material frame 211 and the second material frame 212. The support plate 214 connects at least one of the first material frame 211, the second material frame 212, and the material frame connector 213, and is used to place materials. The guide plate 22 connects at least one of the first material frame 211, the second material frame 212, and the material frame connector 213, and is spaced apart from the support plate 214 in a second direction. This simplifies the structure of the hopper 21.

[0107] The material placed in the hopper 21 is actually placed on the support plate 214, and the side of the support plate 214 near the guide plate 22 is used to support the material with positioning elements. That is, when the material is placed in the hopper, it is located between the support plate 214 and the guide plate 22.

[0108] The material and guide plate 22 moving into the hopper 21 means that they move to the space between the first material frame 211 and the second material frame 212. The material and guide plate 22 moving out of the hopper 21 means that they move out of the gap between the first material frame 211 and the second material frame 212.

[0109] Additionally, the movement of the pusher 33 into the hopper 21 can refer to its movement from the window of the first material frame 211 or the second material frame 212 into the space between the first material frame 211 and the second material frame 212. Specifically, the window of the first material frame 211 extends through the first material frame 211 along a third direction, and the window of the second material frame 212 extends through the second material frame 212 along a third direction.

[0110] For example, such as Figure 7 As shown, in one embodiment, the first material frame 211 is a rectangular frame, which includes a first border 2111, a second border 2112, a third border 2113, and a fourth border 2114 connected in sequence. The two ends of the first border 2111 are connected to the second border 2112 and the fourth border 2114, respectively. The two ends of the third border 2113 are connected to the second border 2112 and the fourth border 2114, respectively. The first border 2111 and the third border 2113 are spaced apart, and the second border 2112 and the fourth border 2114 are spaced apart. At this time, the annular hole (rectangular hole) formed by the first border 2111, the second border 2112, the third border 2113, and the fourth border 2114 is the window of the first material frame 211.

[0111] Furthermore, the first border 2111 is located above the third border 2113, and the second border 2112 and the fourth border 2114 are spaced apart along the first direction. Moreover, when the first direction is a front-back direction, the second border 2112 is located in front of the fourth border 2114.

[0112] like Figure 7 As shown, in one embodiment, the second material frame 212 is a rectangular frame, which includes a fifth border 2121, a sixth border 2122, a seventh border 2123, and an eighth border 2124 connected in sequence. The two ends of the fifth border 2121 are connected to the sixth border 2122 and the eighth border 2124, respectively. The two ends of the seventh border 2123 are connected to the sixth border 2122 and the eighth border 2124, respectively. The fifth border 2121 and the seventh border 2123 are spaced apart, and the sixth border 2122 and the eighth border 2124 are spaced apart. At this time, the annular hole (rectangular hole) formed by the fifth border 2121, the sixth border 2122, the seventh border 2123, and the eighth border 2124 is the window of the first material frame 211.

[0113] Furthermore, the fifth border 2121 is located above the seventh border 2123, and the sixth border 2122 and the eighth border 2124 are spaced apart along the first direction. Moreover, when the first direction is a front-back direction, the sixth border 2122 is located in front of the eighth border 2124.

[0114] In one embodiment, there are multiple material frame connectors 213, and each material frame connector 213 is spaced apart from the others to improve the stability of the material frame.

[0115] When both the first material frame 211 and the second material frame 212 are rectangular frames, the number of material frame connectors 213 can be four, namely the first connector 2131, the second connector 2132, the third connector 2133 and the fourth connector 2134. In this configuration, the first connecting member 2131 connects to the second side frame 2112 and the sixth side frame 2122 at both ends, and the second connecting member 2132 connects to the second side frame 2112 and the sixth side frame 2122 at both ends. The first connecting member 2131 is located above the second connecting member 2132. The first connecting member 2131, the second connecting member 2132, the second side frame 2112, and the sixth side frame 2122 together form a rectangular frame (defined as the first rectangular frame). The third connecting member 2133 connects to the fourth side frame 2114 and the eighth side frame 2124 at both ends, and the fourth connecting member 2134 connects to the fourth side frame 2114 and the eighth side frame 2124 at both ends. The third connecting member 2133 is located above the fourth connecting member 2134. The third connecting member 2133, the fourth connecting member 2134, the fourth side frame 2114, and the eighth side frame 2124 together form a rectangular frame (defined as the second rectangular frame). At this time, the entire hopper 21 has a cuboid structure.

[0116] Furthermore, the guide plate 22 moving into or out of the hopper 21 can mean that it moves into or out of the hopper 21 from the window of the first rectangular frame; or, the guide plate 22 moving into or out of the hopper 21 can mean that it moves into or out of the hopper 21 from the window of the second rectangular frame. The material moving into or out of the hopper 21 can mean that it moves into or out of the hopper 21 from the window of the first rectangular frame; or, the material moving into or out of the hopper 21 can mean that it moves into or out of the hopper 21 from the window of the second rectangular frame.

[0117] The window of the first rectangle extends through the first rectangle along the first direction, and the window of the second rectangle extends through the second rectangle along the first direction.

[0118] In one embodiment, the support plate 214 is connected to the first material frame 211 and the second material frame 212 respectively, so that the support plate 214 is more firmly connected.

[0119] like Figure 6 As shown, in one embodiment, the support plate 214 is located below the guide plate 22, and the material is placed between the support plate 214 and the guide plate 22.

[0120] like Figure 8 As shown, in one embodiment, the hopper 21 further includes a first support member 215 and a second support member 216, wherein the first support member 215 and the second support member 216 are spaced apart along a first direction, the two ends of the first support member 215 are respectively connected to the first material frame 211 and the second material frame 212, and the two ends of the second support member 216 are respectively connected to the first material frame 211 and the second material frame 212. Specifically, the two ends of the first support member 215 are respectively connected to the second side frame 2112 and the sixth side frame 2122, and the two ends of the second support member 216 are respectively connected to the fourth side frame 2114 and the eighth side frame 2124.

[0121] The two ends of the support plate 214 are respectively connected to the first support member 215 and the second support member 216. At the same time, both the first support member 215 and the second support member 216 are located below the support plate 214.

[0122] like Figure 6 As shown, in one embodiment, the support plate 214 includes a first support plate 2141 and a second support plate 2142. The two ends of the first support plate 2141 are respectively connected to a first support member 215 and a second support member 216. The two ends of the second support plate 2142 are respectively connected to the first support member 215 and the second support member 216. The first support plate 2141 and the second support plate 2142 are spaced apart along a third direction.

[0123] The two ends of the material placed on the support plate 214 are respectively placed on the first support plate 2141 and the second support plate 2142.

[0124] Furthermore, the upper surfaces of the first support plate 2141 and the second support plate 2142 can be flush, both lying in the same plane and both perpendicular to the second direction. The first support member 215 and the second support member 216 are both located below the first support plate 2141, and both the first support member 215 and the second support member 216 are both located below the second support plate 2142.

[0125] like Figure 8 As shown, in one embodiment, the hopper 21 further includes a third support member 217 and a fourth support member 218. The two ends of the third support member 217 are respectively connected to the first material frame 211 and the second material frame 212, and the two ends of the fourth support member 218 are respectively connected to the first material frame 211 and the second material frame 212. The third support member 217 and the fourth support member 218 are spaced apart along a first direction. Specifically, the two ends of the third support member 217 are respectively connected to the second side frame 2112 and the sixth side frame 2122, and the two ends of the fourth support member 218 are respectively connected to the fourth side frame 2114 and the eighth side frame 2124. The two ends of the guide plate 22 are respectively connected to the third support member 217 and the fourth support member 218.

[0126] In addition, the first support member 215 is located below the third support member 217, and the two are spaced apart; the second support member 216 is located below the fourth support member 218, and the two are spaced apart. The third support member 217 and the fourth support member 218 are both located above the guide plate 22.

[0127] Furthermore, the aforementioned first material frame, second material frame, material frame connector, first support member 215, second support member 216, third support member 217, and fourth support member 218 constitute the frame of the hopper 21. The movement of materials and guide plates into or out of the hopper 21 refers to their movement into or out of the frame.

[0128] like Figure 9 and Figure 10 As shown, in one embodiment, the hopper 21 further includes a guide rod 219 connected to the frame; the guide plate 22 includes a plate body 222 and a slider 223; the plate body 222 is used to guide the movement of materials along a first direction, that is, the guide structure 221 is disposed on the plate body 222; the slider 223 is movably connected to the guide rod 219 and connected to the guide plate 22, and the slider 223 can slide relative to the guide rod 219 along the first direction to drive the plate body 222 to slide relative to the guide rod 219 along the first direction.

[0129] The guide rod 219 is connected to the third support member 217 and the fourth support member 218 at its two ends, thereby connecting the first material frame 211 and the second material frame 212.

[0130] In addition, the guide rod 219 is spaced between the first material frame 211 and the second material frame 212.

[0131] Furthermore, the movement of the guide plate 22 into the hopper 21 mainly refers to the movement of the plate 222 into the hopper 21; the movement of the guide plate 22 out of the hopper 21 mainly refers to the movement of the plate 222 out of the hopper 21. Moreover, the slider 223 is located on the side of the plate 222 away from the support plate 214, that is, the slider 223 can be located above the plate 222.

[0132] like Figure 11 As shown, in one embodiment, the slider 223 is provided with a guide hole 2230, which passes through the slider 223 along a first direction, and the guide rod 219 passes through the guide hole 2230 to achieve sliding cooperation with the slider 223.

[0133] In one embodiment, there are multiple first support members 215, second support members 216, third support members 217, fourth support members 218, support plates 214, and guide plates 22, and each of the six corresponds to the other. The support plate 214 is connected to its corresponding first support member 215 and second support member 216, and is located below its corresponding guide plate 22. The guide plate 22 is connected to its corresponding third support member 217 and fourth support member 218, and is spaced apart from its corresponding support plate to guide the material placed on its corresponding support plate 214.

[0134] In addition, the first support member 215, the second support member 216, the third support member 217, the fourth support member 218, the support plate 214 and the guide plate 22, which correspond one-to-one, form a storage unit, and each storage unit is arranged at intervals along the second direction.

[0135] Furthermore, each storage unit is connected to at least one guide rod 219, and the guide plate 22 in a storage unit is guided by its corresponding guide rod 219. When a storage unit corresponds to multiple guide rods 219, each guide rod 219 is spaced apart along a third direction. In this case, a slider 223 is provided with multiple guide holes 2230, and a guide rod 219 passes through one of the guide holes 2230.

[0136] In one embodiment, a guide plate 22 has a plurality of sliders 223, and the sliders 223 of a guide plate 22 are spaced apart along a first direction.

[0137] like Figure 7 As shown, in one embodiment, the hopper 21 further includes a first material frame reinforcement 21a; in the second direction, the two ends of the first material frame reinforcement 21a are respectively connected to the first material frame 211; in the first direction, both sides of the first material frame reinforcement 21a are spaced apart from the first material frame 211.

[0138] Specifically, the two ends of the first material frame reinforcement 21a are connected to the first side frame 2111 and the third side frame 2113 respectively, and the first material frame reinforcement 21a, the second side frame 2112 and the fourth side frame 2114 are all spaced apart.

[0139] In addition, the number of first material frame reinforcing members 21a is greater than or equal to one. When there are multiple first material frame reinforcing members 21a, each first material frame reinforcing member 21a is spaced apart along the first direction.

[0140] like Figure 7 As shown, in one embodiment, the hopper 21 further includes a second material frame reinforcement 21b; in the second direction, both ends of the second material frame reinforcement 21b are respectively connected to the second material frame 212; in the first direction, both sides of the second material frame reinforcement 21b are spaced apart from the second material frame 212.

[0141] Specifically, the two ends of the second frame reinforcement 21b are connected to the fifth frame 2121 and the seventh frame 2123 respectively, and the second frame reinforcement 21b, the sixth frame 2122 and the eighth frame 2124 are all spaced apart.

[0142] In addition, the number of second material frame reinforcing members 21b is greater than or equal to one. When there are multiple second material frame reinforcing members 21b, each second material frame reinforcing member 21b is spaced apart along the first direction.

[0143] like Figure 7 As shown, in one embodiment, the hopper 21 further includes a third material frame reinforcement 21c; in the third direction, the two ends of the third material frame reinforcement 21c are respectively connected to the middle part of the first material frame 211 and the middle part of the second material frame 212.

[0144] Specifically, the two ends of the third frame reinforcement 21c are connected to the first frame 2111 and the fifth frame 2121 respectively, and the third frame reinforcement 21c, the first connector 2131 and the third connector 2133 are all spaced apart.

[0145] In addition, the number of third material frame reinforcing members 21c is greater than or equal to one. When there are multiple third material frame reinforcing members 21c, each third material frame reinforcing member 21c is spaced apart along the first direction.

[0146] like Figure 7 As shown, in one embodiment, the hopper 21 further includes a fourth material frame reinforcement 21d; in the third direction, the two ends of the fourth material frame reinforcement 21d are respectively connected to the middle part of the first material frame 211 and the middle part of the second material frame 212.

[0147] Specifically, the two ends of the fourth frame reinforcement 21d are connected to the third frame 2113 and the seventh frame 2123 respectively, and the fourth frame reinforcement 21d, the second connector 2132 and the fourth connector 2134 are all spaced apart.

[0148] In addition, the number of fourth material frame reinforcing members 21d is greater than or equal to one. When there are multiple fourth material frame reinforcing members 21d, each fourth material frame reinforcing member 21d is spaced apart along the first direction.

[0149] like Figure 8 As shown, in one embodiment, the hopper 21 further includes a fifth support member 21e, the two ends of which are respectively connected to the first material frame reinforcement member 21a and the second material frame reinforcement member 21b, and the support plate 214 is connected to the fifth support member 21e. Furthermore, the fifth support member 21e is located below the support plate 214.

[0150] like Figure 8 As shown, in one embodiment, the hopper 21 further includes a sixth support member 21f, the two ends of which are respectively connected to the first material frame reinforcement member 21a and the second material frame reinforcement member 21b, and are guided and connected to the fifth support member 21e. Furthermore, the sixth support member 21f is located below the guide plate 22.

[0151] like Figure 10 As shown, in one embodiment, the guide structure 221 is a guide groove, the length direction of which is a first direction, and the guide groove passes through the guide plate 22 along the first direction. This arrangement facilitates the entry or exit of the positioning element from the guide groove.

[0152] The guide groove penetrates the guide plate 22 along the first direction, which actually means that the guide groove penetrates the plate 222 along the first direction.

[0153] At this point, the positioning element can be a guide post, or more specifically, a pin.

[0154] like Figure 10 As shown, in one embodiment, the guide groove also penetrates the guide plate 22 in the second direction. That is, in the second direction, the guide groove penetrates the plate 222.

[0155] like Figure 10 As shown, in one embodiment, the plate 222 includes a first plate 2221 and a second plate 2222, which are spaced apart in the third direction. The gap between the first plate 2221 and the second plate 2222 is a guide groove.

[0156] In one embodiment, the upper surface of the first plate 2221 and the upper surface of the second plate 2222 are flush, and both upper surfaces can be planes and are perpendicular to the second direction. The lower surface of the first plate 2221 and the lower surface of the second plate 2222 are flush, and both lower surfaces can be planes and are perpendicular to the second direction.

[0157] like Figure 10 As shown, in one embodiment, the guide plate 22 further includes a rolling element 224 connected to the plate body 222 and capable of rotating relative to the plate body 222 about its own axis; wherein, the axis of the rolling element 224 is parallel to a third direction. Furthermore, the rolling element 224 protrudes from the plate body 222 along the direction from the guide plate 22 to the support plate 214 (i.e., from top to bottom). When an object such as a material abuts against the guide plate 22 from bottom to top, it actually abuts against the rolling element 224. When the guide plate 22 moves relative to the object in the first direction, the rolling element 224 can rotate about its own axis, thereby reducing the friction between the guide plate 22 and the object.

[0158] When the plate body 222 includes a first plate 2221 and a second plate 2222, both the first plate 2221 and the second plate 2222 are provided with rolling elements 224. Furthermore, the rolling elements 224 on the first plate 2221 protrude downwards from the first plate 2221, and the rolling elements 224 on the second plate 2222 protrude downwards from the second plate 2222. Additionally, the first plate 2221 may be provided with multiple rolling elements 224, and these rolling elements 224 are spaced apart along a first direction; similarly, the second plate 2222 may be provided with multiple rolling elements 224, and these rolling elements 224 are spaced apart along the first direction.

[0159] like Figure 10 As shown, in one embodiment, the guide plate 22 further includes a guide member 225, which is connected to the plate body 222 and the two are arranged along a first direction. The guide member 225 is provided with a guide groove 2251, which passes through the guide member 225 along the first direction and is opposite to the guide slot, so that the positioning element can move from the guide groove 2251 into the guide slot, and the positioning element can move from the guide slot into the guide groove 2251.

[0160] In the direction from the guide member 225 to the plate 222, the width of the guide groove 2251 gradually decreases in the third direction. That is, in the first direction, the width of the end of the guide groove 2251 away from the plate 222 is greater than the width of the end of the guide groove 2251 close to the plate 222, which facilitates guiding the positioning elements on the material into the guide groove.

[0161] In the first direction, the guide groove 2251 may be the surface of the extended guide 225 away from the plate 222, and may extend to the surface of the guide 225 close to the plate 222.

[0162] like Figure 10 As shown, the guide 225 includes a first guide plate 2252 and a second guide plate 2253. The first guide plate 2252 is connected to the first plate 2221, and the second guide plate 2253 is connected to the second plate 2222. The gap between the first guide plate 2252 and the second guide plate 2253 forms a guide groove 2251.

[0163] In addition, the first guide plate 2252 is detachably connected to the first plate 2221, and the second guide plate 2253 is detachably connected to the second plate 2222. This reduces maintenance costs.

[0164] In one embodiment, in the first direction, both ends of the plate 222 can be connected to the guide 225.

[0165] Alternatively, the guide 225 may also be provided with a rolling element 224, wherein the rolling element 224 can rotate relative to the guide 225 about its own axis. In addition, the rolling element 224 connected to the guide 225 protrudes from the surface of the guide 225 away from the plate 222, and it protrudes from the guide 225 from top to bottom and from the guide 225 from bottom to top.

[0166] In other embodiments, the guide 225 is further provided with a transition groove. In the first direction, the transition groove is located between the guide groove and the guide groove 2251, and the transition groove connects the guide groove and the guide groove 2251. When the material moves along the first direction, the positioning element on it can first enter the guide groove 2251, then enter the transition groove, and then enter the guide groove. At this time, the gap between the first guide plate 2252 and the second guide plate 2253 forms the guide groove 2251 and the transition groove.

[0167] like Figure 10 As shown, in one embodiment, the guide plate 22 further includes a buffer 226 connected to the slider 223. When the pusher 33 pushes the slider 223, it may abut against the buffer 226. That is, the slider 223 receives external force through the buffer 226, thus preventing the slider 223 from being subjected to rigid collisions. The buffer 226 may be a hydraulic buffer, a rubber buffer, or a spring buffer, etc.

[0168] like Figure 10 As shown, in one embodiment, the guide plate 22 further includes a push block 227, which is connected to the slider 223. When the drive module 3 drives the slider to move in the first direction, it is actually the pusher 33 that pushes the push block 227 to move in the first direction, thereby driving the slider 223 to move in the first direction.

[0169] Additionally, push block 227 is disposed on the side of slider 223, wherein, in the third direction, push block 224 is located on the side of slider 223 closer to drive module 3.

[0170] In addition, the buffer 226 is connected to the push block 227, thereby achieving its connection on the slider 223.

[0171] like Figure 10 and Figure 11 As shown, in one embodiment, the storage module 2 further includes a limiting unit 24, which is used to generate a preload between the slider 223 and the guide rod 219 to prevent the slider 223 from wobbling relative to the guide rod 219.

[0172] The limiting unit 24 includes a limiting block 241 and a limiting elastic element 242. Both the limiting block 241 and the limiting elastic element 242 are connected to the slider 223. The limiting block 241 can move relative to the slider 223 in a third direction to approach or move away from the guide rod 219. One end of the limiting block 241 can abut against the guide rod 219, and the other end of the limiting block 241 can abut against the limiting elastic element 242. The limiting elastic element 242 is disposed between the limiting block 241 and the slider 223 and can apply an elastic force to the limiting block 241 to press the limiting block 241 onto the guide rod 219. This generates a preload between the slider 223 and the guide rod 219.

[0173] In this embodiment, the elastic force applied by the limiting elastic member 242 to the limiting block 241 forces the limiting block 241 to abut against the guide rod 219, so that friction is generated between the limiting block 241 and the guide rod 219. When no external force is applied to the slider 223 or the guide plate 22, the static friction between the limiting block 241 and the guide rod 219 plays a pre-tightening role on the slider 223, preventing the slider 223 from moving.

[0174] The limiting block 241 and the limiting elastic element 242 are both located inside the slider 223. One end of the limiting block 241 abuts against the guide rod 219, and the other end abuts against the limiting elastic element 242.

[0175] like Figure 11As shown, in one embodiment, the slider 223 includes a sliding body 2231 and a limiting baffle 2232. A guide hole 2230 is disposed on the sliding body 2231, and the sliding body 2231 is connected to the guide plate 22. The outer surface of the sliding body 2231 is provided with a receiving hole 2233, which extends to communicate with the guide hole 2230. The limiting baffle 2232 is connected to the sliding body 2231 and is opposite to the receiving hole 2233. The limiting elastic member 242 is located in the receiving hole 2233 and is compressed between the limiting baffle 2232 and the limiting block 241. The limiting block 241 is located in the receiving hole 2233 and abuts against the guide rod 219 in the guide hole 2230.

[0176] The limiting elastic element 242 can be a helical spring, etc. The limiting block 241 can be a cylindrical structure, etc.

[0177] In one embodiment, the end of the limiting block 241 facing the guide rod 219 has an arc surface that fits against the guide rod. This allows for a closer contact between the two. In this case, the guide rod 219 can be a cylindrical structure.

[0178] In another embodiment, the end of the limiting block 241 near the guide rod 219 is provided with an arc-shaped groove, which penetrates the limiting block 241 along a first direction. The guide rod 219 is located in the arc-shaped groove and abuts against the bottom surface of the arc-shaped groove, wherein the bottom surface of the arc-shaped groove is the aforementioned arc surface. The end face of the limiting block 241 away from the guide rod 219 is provided with a receiving groove 111. One end of the limiting elastic member 242 is located in the receiving groove 111 and abuts against the bottom surface of the receiving groove 111. The limiting baffle 2232 is connected to the surface of the sliding body 2231 and can close the opening formed by the receiving hole 2233 on the outer surface of the sliding body 2231. The other end of the limiting elastic member 242 abuts against the limiting baffle 2232.

[0179] It should be noted that the limiting elastic element 242 is always in a compressed state in the receiving groove 111, thereby applying an elastic force toward the guide rod 219 to the limiting block 241, so that the limiting block 241 always abuts against the guide rod 219.

[0180] In addition, the limiting baffle 2232 and the sliding body 2231 can be detachably connected together by screws or the like. Of course, the limiting baffle 2232 can also be glued or welded to the sliding body 2231.

[0181] like Figure 10 and Figure 12As shown, in one embodiment, the storage module 2 further includes a floating unit 25. One end of the floating unit 25 is connected to the hopper 21, and the other end is connected to the guide plate 22, so that the guide plate 22 can move in a direction closer to or further away from the support plate. The floating unit 25 allows the guide plate 22 to adaptively adjust the gap with the support plate 214 in the second direction. This avoids both excessively large gaps between the guide plate 22 and the support plate 214, which could cause the second positioning structure to detach from the guide groove, and excessively small gaps between the guide plate 22 and the support plate 214, which could make it difficult for materials to move in or out of the hopper 21 in the first direction.

[0182] In one embodiment, the floating unit 25 is connected to the plate 222 and the slider 223, respectively, allowing the plate 222 to move relative to the slider 223 in a second direction. This adjusts the distance between the plate 222 and the support plate 214, thereby adjusting the distance between the guide plate 22 and the support plate 214. Specifically, the floating unit 25 being connected to the guide plate 22 refers to its connection to the plate 222. Furthermore, the floating unit 25 is connected to the hopper 21 via the slider 223. The guide plate 22 moving closer to or further away from the support plate 214 refers to the plate 22 moving closer to or further away from the support plate 214.

[0183] like Figure 12 As shown, in one embodiment, the floating unit 25 includes a first floating connector 251 and a floating elastic member 253. The first floating connector 251 is connected to the hopper 21, and the floating elastic member 253 is disposed between the guide plate 22 and the first floating connector 251. When the guide plate 22 moves towards or away from the support plate 214, it can release or compress the floating elastic member 253. In one scenario, when the guide plate 22 approaches the support plate 214, it can compress the floating elastic member 253; when the guide plate 22 moves away from the support plate 214, it can release the floating elastic member 253.

[0184] like Figure 12 As shown, in one embodiment, the floating unit 25 further includes a second floating connector 252, which is connected to the plate 222. The second floating connector 252 is movably connected to the first floating connector 251, so that the plate 222 can reciprocate relative to the first floating connector 251 in the second direction with the second floating connector 252, so as to move closer to or away from the first floating connector, thereby realizing that the plate 222 moves closer to or away from the support plate 214 in the second direction.

[0185] The first floating connector 251 is actually connected to the sliding body 2231. When the plate 222 moves close to the first floating connector 251, it can apply force to the floating elastic member 253, causing the floating elastic member 253 to deform elastically.

[0186] In this example, when the material is thicker in the second direction, it will force the plate 222 to move away from the support plate 214 (i.e., move upward), so that the distance between the plate 222 and the support plate 214 is appropriate, so as not to affect the movement of the material in the first direction; when the material is thinner and does not touch the plate 222, the plate 222 will be in a position close to the support plate 214 under the elastic force of the floating elastic element 253.

[0187] In addition, in actual scenarios, the elastic force of the floating elastic element 253 can also be used to press the plate 222 onto the material placed on the support plate 214, so that the material is placed more stably in the hopper 21.

[0188] like Figure 12 As shown, in this embodiment, the lower surface of the slider 223 (i.e. the surface near the plate 222) is provided with a mounting hole 2234, and the first floating connector 251 is installed in the mounting hole 2234.

[0189] In one embodiment, the mounting hole 2234 extends through the slider 223 along a second direction, and specifically, the mounting hole 2234 is provided on the sliding body 2231.

[0190] Mounting hole 2234 includes a first hole and a second hole, which are connected. The diameter of the first hole is larger than the diameter of the second cutting edge, forming a stepped surface between them. In addition, the first hole is located above the second hole. The first floating connector 251 is installed in the first hole and abuts against the stepped surface. This arrangement facilitates the installation of the first floating connector 251.

[0191] The first hole can extend downward from the upper surface of the sliding body 2231 (i.e., the upper surface of the slider 223), and the second hole can extend downward from the bottom surface of the first hole to the lower surface of the sliding body 2231 (i.e., the lower surface of the slider 223).

[0192] The first floating connector 251 has a movable hole, which extends through the first floating connector 251 along a second direction, and the second floating connector 252 passes through the movable hole. Specifically, the second floating connector 252 also passes through the first hole and the second hole.

[0193] In this embodiment, the first floating connector 251 and the first hole can be an interference fit, a transition fit, or a clearance fit. The second floating connector and the movable hole can be a clearance fit or a transition fit.

[0194] like Figure 12As shown, in one embodiment, the second floating connector 252 includes a first connecting portion 2521, a second connecting portion 2522, and a limiting portion 2523 connected together. In a second direction, the second connecting portion 2522 is located between the limiting portion 2523 and the first connecting portion 2521. The first connecting portion 2521 is located below the second connecting portion 2522 and connects to the plate 222. The second connecting portion 2522 passes through the movable hole and the mounting hole 2234 and can move up and down relative to the first floating member and the slider 223 in the second direction. The limiting portion 2523 is located above the second connecting portion 2522 and is used to limit the maximum distance of the second connecting portion 2522 moving downward, thereby limiting the maximum distance of the plate 222 moving closer to the support plate 214.

[0195] In one embodiment, the surface of the plate 222 facing away from the support plate 214 is provided with a fixing hole, and the first connecting part 2521 is installed in the fixing hole. The two can be threaded together. In this case, the first connecting part 2521 is provided with an external thread, and the inner surface of the fixing hole is provided with an internal thread.

[0196] In one embodiment, both the first connecting portion 2521 and the second connecting portion 2522 can be cylindrical structures, coaxially arranged, and the diameter of the second connecting portion 2522 is larger than the diameter of the first connecting portion 2521. After assembly, the second connecting portion 2522 can abut against the plate 222.

[0197] In addition, the fixed hole is a stepped hole, at which time the second connecting part 2522 can extend into the fixed hole and abut against the stepped surface of the fixed hole.

[0198] like Figure 12 As shown, the floating unit 25 also includes a cover plate 254, which is connected to the side of the plate 222 away from the support plate 214. The cover plate 254 has a through hole that extends through the cover plate 254 along a second direction. The second connecting part 2522 is movably inserted into the through hole. The limiting part 2523 is located on the side of the cover plate 254 away from the plate 222. When the second connecting part 2522 moves downward, the limiting part 2523 can abut against the cover plate 254, thereby limiting its maximum downward movement distance.

[0199] The limiting part 2523 can also be a cylindrical structure, coaxially arranged with the second connecting part 2522, and its diameter is larger than that of the second connecting part 2522. Simultaneously, the diameter of the limiting part 2523 is larger than the diameter of the through hole. It should be understood that in some embodiments, the cover plate 254 may not be provided. In this case, when the second connecting part 2522 moves downward, the limiting part 2523 can abut against the first floating member to limit the maximum downward distance of the second connecting part 2522.

[0200] In one embodiment, the floating elastic element 253 can be a helical spring. The floating elastic element 253 is sleeved on the second connecting part 2522, and the upper part of the floating elastic element 253 passes through the second hole of the mounting hole 2234. The upper end face of the floating elastic element 253 abuts against the lower end face of the first floating connecting part 251, and the lower end face of the floating elastic element 253 abuts against the plate 222. This arrangement can control the deformation path of the floating elastic element 253 and prevent its radial deviation.

[0201] In one embodiment, when the plate 222 includes a first plate 2221 and a second plate 2222, at least two floating units 25 may be provided, wherein the first plate 2221 is connected to the slider 223 through at least one floating unit 25, and the second plate 2222 is also connected to the slider 223 through at least one floating unit 25.

[0202] like Figure 13 and Figure 14 As shown, in one embodiment, the storage module 2 further includes a pressure plate assembly 26 and a pallet assembly 27; both the pressure plate assembly 26 and the pallet assembly 27 are connected to the hopper 21; in the second direction, the pressure plate assembly 26 and the pallet assembly 27 respectively abut against both sides of the guide plate 22. This can prevent the guide plate 22 from bending and deforming in the second direction.

[0203] In addition, the pressure plate assembly 26 and the support plate assembly 27 actually abut against the upper and lower sides of the plate body 222 respectively.

[0204] The plate 222 is connected to the guide plate 22 via a slider 223.

[0205] During the process of removing the plate 222 from the hopper 21, the portion of the plate 222 that is removed from the hopper 21 lacks support and is prone to bending. Therefore, the pressure plate assembly 26 and the pallet assembly 27 can be connected to the outlet end of the hopper 21 (i.e., the discharge end of the hopper). During operation, when the guide plate is removed from the discharge end of the hopper, it can be supported by the pallet assembly 27 to prevent bending and deformation. For example, in the first direction, the pressure plate assembly 26 and the pallet assembly 27 can be connected to the end where the first connector 2131 is located; or, in the first direction, the pressure plate assembly 26 and the pallet assembly 27 can be connected to the end where the third connector 2133 is located; or, both the end where the first connector 2131 is located and the end where the third connector 2133 is located are provided with pressure plate assembly 26 and pallet assembly 27.

[0206] like Figure 13As shown, in one embodiment, the pressure plate assembly 26 includes a pressure roller connector 261, a pressure roller 262, and a pressure plate elastic member 263. The pressure roller connector 261 is connected to the hopper 21 and is movable relative to the hopper 21 in a second direction. The pressure roller 262 is connected to the pressure roller connector 261 and is rotatable relative to the pressure roller connector 261 about its own axis. The pressure plate elastic member 263 is disposed between the connecting unit and the pressure roller connector 261 and applies an elastic force toward the plate body 222 to the pressure roller connector 261, so that the pressure roller 262 abuts against the plate body 222.

[0207] The pressure roller 262 may be in contact with the side of the plate 222 away from the support plate 214.

[0208] like Figure 13 As shown, the pressure plate assembly 26 also includes a mounting plate 264, which is connected to the hopper 21. The mounting plate 264 has a pressure roller hole 2641 on its surface near the plate body 222 (i.e., the lower surface of the mounting plate 264). The pressure plate elastic member 263 and the pressure roller connecting member 261 are both located within the pressure roller hole 2641. One end of the pressure plate elastic member 263 abuts against the bottom surface of the pressure roller hole 2641, and the other end of the pressure plate elastic member 263 abuts against the pressure roller connecting member 261.

[0209] Additionally, the lower end of the pressure roller connector 261 extends out of the pressure roller hole 2641 and connects to the pressure roller 262. The axis of the pressure roller 262 can be parallel to a third direction.

[0210] Furthermore, the wall of the pressure roller hole 2641 can limit the movement of the pressure roller connector 261, thereby guiding the movement of the pressure roller connector 261 in the second direction. Alternatively, a corresponding guide component can be provided within the pressure roller hole 2641 to guide the movement of the pressure roller connector 261 in the second direction.

[0211] like Figure 13 As shown, the pressure plate assembly 26 also includes a limiting member 265, which is connected to the mounting plate 264 and can abut against the pressure roller connector 261 to prevent the pressure roller connector 261 from moving downward out of the pressure roller hole 2641.

[0212] like Figure 14 As shown, the mounting plate 264 has a connecting hole 264 that extends through the mounting plate 264 along a first direction. A guide rod 219 passes through the connecting hole and is fixedly connected to the mounting plate 264. That is, the mounting plate 264 is connected to the hopper 21 via the guide rod 219. Of course, in other embodiments, the mounting plate 264 can also be directly connected to the hopper 21, for example, it can be directly connected to the third support member 217.

[0213] like Figure 1As shown, in one embodiment, the pallet assembly 27 includes a roller connector 271 and a roller 272. The roller connector 271 is connected to the hopper 21. The roller 272 is connected to the roller connector 271 and is rotatable relative to the roller connector 271 about its own axis. The roller 272 is located below the plate body 222 and abuts against the side of the plate body 222 away from the pressure roller 262.

[0214] The axis of the support roller 272 can be parallel to a third direction.

[0215] Alternatively, the upper end of the roller connector 271 can be connected to the mounting plate 264, thereby achieving a connection with the hopper 21. Or, the upper end of the roller connector 271 can be directly connected to the hopper 21, for example, it can be directly connected to the third support member 217.

[0216] When the plate 222 includes the first plate 2221 and the second plate 2222, the upper and lower sides of the first plate 2221 are in contact with the pressure plate assembly 26 and the support plate assembly 27, and the upper and lower sides of the second plate 2222 are also in contact with the pressure plate assembly 26 and the support plate assembly 27.

[0217] like Figure 15 As shown, in one embodiment, the conveying device 10 further includes a walking module 4, which is connected to the support module 1 and is used to drive the support module 1 to move, thereby moving the hopper 21.

[0218] During operation, the hopper 21 can be moved to a suitable position by the walking module 4 to perform material loading (i.e., placing materials from other devices into the hopper 21) and unloading (i.e., transporting materials from the hopper 21 to the target workstation).

[0219] Among them, the walking module 4 can be an AGV (Automated Guided Vehicle) or similar vehicle.

[0220] like Figure 15 As shown, this utility model embodiment also provides a loading and unloading system, which includes a buffer device 20 and a conveying device 10 described in any of the above. The buffer device 20 is used to buffer materials, and the buffer device 20 can exchange materials with the silo.

[0221] Specifically: when the hopper and the buffer device 20 are aligned, the material buffered on the buffer device 20 can be moved into the hopper; of course, when the hopper and the buffer device 20 are aligned, the material in the hopper can also be moved into the buffer device 20 to buffer the material.

[0222] like Figure 16 and ​As shown, this utility model embodiment also provides a PCB processing equipment, which includes a host 30 and a conveying device 10 described in any of the above-mentioned embodiments, the conveying device being able to exchange materials with the host 30; or, the PCB processing equipment includes a host 30 and the above-mentioned loading and unloading system, the buffer device 20 being able to exchange the materials with the host 30.

[0223] The main unit 30 is used to process materials, and it can also exchange materials with the hopper. Specifically, when the hopper is aligned with the main unit 30, the materials in the hopper can be moved to the main unit 30; of course, when the hopper is aligned with the main unit 30, the materials on the main unit 30 can also be moved into the hopper.

[0224] Furthermore, when moving materials from the hopper to the buffer device 20 or the main unit 30, the material can be moved by the aforementioned drive module. When it is necessary to move materials from the buffer device 20 or the main unit 30 to the hopper, the material can be moved by the aforementioned drive device, or other devices capable of moving materials can be used.

[0225] In one embodiment, the conveying device 10 further includes a position detection component connected to the traveling device, used to detect the relative position of the traveling device and the buffer device 20 or the host 30, so that the hopper is aligned with the buffer device 20 or the host 30. The position detection component can be a vision detection component or a radar device, etc.

[0226] This utility model embodiment also provides a material conveying method, which is applied to the conveying device described in any of the above embodiments to control the operation of the conveying device. The method includes the following steps: Step S1, driving the guide plate to move so that the guide plate reaches the loading position; Step S2, driving the material to move along the guide plate so that the material is removed from the hopper.

[0227] In step S1, the guide plate 22 is driven by the drive module 3. In step S1, the drive module 3 drives the guide plate 22 to move forward in the first direction, so that the guide plate 22 moves out of the hopper 21 and reaches the loading position.

[0228] In step S2, the material is actually driven by the driving module 3. Specifically, in step S2, the driving module 3 drives the material on the support plate 214 to move forward in the first direction, causing the material to be removed from the hopper 21.

[0229] The control of drive module 3 can be accomplished through a controller, meaning the controller can drive the corresponding drive components within drive module 3 to operate. Furthermore, the controller stores a corresponding program, which, when executed, controls the conveyor device 10 to perform the aforementioned steps. The controller can be a computer, a microcontroller, or a PLC, etc.

[0230] Furthermore, when the drive guide plate 22 and the material move in opposite directions in the first direction, they can be driven into the hopper 21.

[0231] In one application scenario, the direction from the first rectangular frame to the second rectangular frame is the positive direction of the first direction. That is, when the guide plate 22 and the material move in the positive direction of the first direction, they are actually moving along the direction from the first rectangular frame to the second rectangular frame. When the guide plate 22 and the material move in the opposite direction of the first direction, they are actually moving along the direction from the second rectangular frame to the first rectangular frame.

[0232] Furthermore, when the pusher 33 pushes the guide plate 22 to move in the first direction, the pusher 33 actually abuts against the push block 227, and by applying force to the push block 227, it drives the entire guide plate 22 to reciprocate in the first direction.

[0233] Before step S1, there is also step S0, wherein step S0 is: controlling the pusher 33 to move in the second direction to align the guide plate 22, so that when the pusher 33 moves in the first direction, it can push the guide plate 22 aligned with it to move in the first direction.

[0234] Specifically, the controller controls the first drive assembly 31 to adjust the position of the pusher 33 in the second direction, thereby aligning the pusher 33 with the guide plate 22. Subsequently, the controller controls the second drive assembly 32 to drive the pusher 33 to move forward in the first direction.

[0235] Of course, before step S0, it also includes: controlling the third drive component 34 to work so that the pusher 33 rotates into the hopper 21.

[0236] At the start of operation (e.g., before or during step S0), the pusher 33 is in its initial position in the first direction, at which point it may be located within the hopper 21. During the operation of driving the pusher 33 to move in the second direction to align with the guide plate 22 or the material, the pusher 33 may remain within the hopper 21.

[0237] Step S2 specifically includes: Step S21, driving the pusher to move along the second direction to align with the material; Step S22, driving the pusher to move along the first direction to remove the material from the hopper.

[0238] After step S1 is executed, the pusher 33 is first driven to move in the opposite direction to the initial position. Then, step S21 is executed.

[0239] The process includes step S3 after step S2, which involves driving the pusher to rotate in order to push the material away from the hopper.

[0240] Specifically, the third drive component drives the pusher to rotate, causing it to continue pushing the material forward in the first direction, so that it can move to a position further away from the hopper.

[0241] Following step S2 are steps S4 and S5, where step S4 involves retracting the drive guide plate and aligning it with the material. Step S5 involves moving the drive guide plate to push the material away from the hopper. This allows the material to be moved a greater distance.

[0242] The retraction of the drive guide plate means that the drive guide plate moves in the opposite direction of the first direction, so that it moves into the hopper.

[0243] In step S4, the material aligned with the guide plate is the material that has been removed from the hopper. When the guide plate is aligned with the material, if the guide plate is driven to move forward in the first direction, the guide plate can contact the material and push the material to continue moving forward in the first direction.

[0244] Alternatively, step S4 can be executed after step S3 has been completed.

[0245] When the drive module includes a pusher and the guide plate is provided with a push block; if the number of pushers is one, then step S1 above specifically involves: driving the pusher to move the push block, thereby moving the guide plate. The step S4 above, "driving the guide plate to retract," specifically involves: driving the pusher to push the push block in the opposite direction, thereby retracting the guide plate.

[0246] If there are two pushing components, namely the first pushing component and the second pushing component, then step S1 above specifically involves driving the first pushing component to move the push block, thereby moving the guide plate. The step S4 above, "driving the guide plate to retract," specifically involves driving the second pushing component to move the push block in the opposite direction, thereby retracting the guide plate.

[0247] When there is one pusher, the guide plate is driven to move into or out of the hopper by the cooperation of the pusher and the push block. When there are two pushers, one pusher is used to drive the guide plate out of the hopper by cooperating with the push block, and the other pusher is used to drive the guide plate into the hopper by cooperating with the push block.

[0248] In addition, the first pusher and the second pusher can be arranged at intervals along the first direction.

[0249] In one embodiment, when there are multiple pushers 33, each pusher 33 can be used sequentially to drive the material (or guide plate) to move a certain distance along the first direction, so that the final distance the material moves in the positive direction of the first direction meets the requirements. Taking two pushers 33 as an example, the two are the first pusher and the second pusher, wherein the direction from the first pusher to the second pusher is the positive direction of the first direction. In this case, step S2 includes: step S21, driving the first pusher to move in the positive direction of the first direction to push the material (or guide plate) to move a first distance in the positive direction of the first direction. At this time, the first pusher is located inside the hopper 21 and the second pusher is located outside the hopper 21; step S12, driving the first pusher to reset to the initial position. At this time, the second pusher is also reset to the initial position; step S13, driving the second pusher to rotate into the hopper 21 and aligning the second pusher 33 with the material (or guide plate); step S14, driving the second pusher to move in the positive direction of the first direction so that the material (or guide plate) can continue to move in the positive direction of the first direction through the second pusher.

[0250] In this embodiment, the first pusher 33 and the second pusher 33 can push different sliders 223 to make the guide plate 22 move in the positive direction of the first direction. For example, there are also two sliders 223, namely the first slider and the second slider, wherein the direction from the first slider to the second slider is the positive direction of the first direction.

[0251] In step S1, the guide plate 22 is pushed to move forward in the first direction. This can actually be achieved by the first pusher pushing the second slider to move forward in the first direction. In step S4, the second pusher 33 can push the first slider 223 to retract the guide plate 22.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
