[0001] This application relates to the field of automatic feeding equipment technology, specifically to a feeding device. Background Technology

[0002] In today's electronics manufacturing industry, many electronic products inevitably involve the crucial PCBA (Printed Circuit Board Assembly) component. However, it's worth noting that despite continuous technological advancements, on many production lines, PCBA assembly still heavily relies on manual labor or individual carriers for loading. This approach is not only time-consuming and labor-intensive but also inefficient, failing to meet the demands of modern large-scale production. Therefore, improving PCBA assembly technology and increasing production efficiency has become a pressing issue for the electronics manufacturing industry. Utility Model Content

[0003] This application provides a feeding device for improving production efficiency.

[0004] In some embodiments, the feeding device includes a feeding area, a picking area, and a discharging area, and further includes a separating mechanism, a conveying mechanism, and a tray for holding materials. The conveying mechanism is configured to sequentially convey the tray from the feeding area to the picking area and the discharging area along a first direction. The separating mechanism is provided corresponding to the picking area and is configured to move along a second direction that is not parallel to the first direction. During its movement, the separating mechanism can act on the tray conveyed to the picking area to drive the tray away from the conveying mechanism and wait for material to be picked up. After material is picked up, the empty tray is returned to the conveying mechanism of the picking area by the separating mechanism, so that the tray is conveyed to the discharging area by the conveying mechanism.

[0005] In some embodiments, the separation mechanism includes a first positioning structure, and the tray is provided with a positioning engagement structure that movably engages with the first positioning structure; wherein...

[0006] When the separation mechanism acts on the pallet in the material picking area, the separation mechanism can move the pallet and the first positioning structure and the positioning mating structure are inserted and mated.

[0007] When the separation mechanism separates from the pallet in the picking area, the pallet returns to the conveying mechanism in the picking area and the first positioning structure and the positioning mating structure are disengaged.

[0008] In some embodiments, the tray is provided with a second positioning structure, and the second positioning structure and the positioning mating structure are respectively disposed on opposite sides of the tray;

[0009] The loading area or the unloading area is configured to stack multiple pallets, and when multiple pallets are stacked, the second positioning structure on one pallet is inserted into the positioning mating structure on the adjacent pallet.

[0010] In some embodiments, the material picking area is provided with a stop, and the separation mechanism is configured to drive the pallet to move between the conveying mechanism and the stop, and when the pallet is moved by the separation mechanism to contact or approach the stop, control the pallet to stop moving along the original direction of movement to wait for material picking.

[0011] In some embodiments, the feeding device further includes a first position sensor for detecting the position of the pallet in the picking area, and the separating mechanism is configured to drive the pallet from the conveying mechanism toward the stop in response to the detection signal of the first position sensor;

[0012] And / or, the feeding device further includes a second position sensor for detecting the position of the pallet in the feeding area, and the separation mechanism is configured to stop the pallet from continuing to move toward the stop in response to the detection signal of the second position sensor.

[0013] In some embodiments, the separation mechanism includes a driving member, a guide member, and a moving member. The guide member is disposed along the second direction, the moving member is connected to the driving member, the moving member is slidably connected to the guide member, and the first positioning structure is fixed on the moving member.

[0014] In some embodiments, the feeding area is provided with a first storage component and a sorting mechanism corresponding to the first storage component. Multiple pallets can be stacked on the first storage component, and the sorting mechanism is used to sort the multiple pallets one by one onto the conveying mechanism.

[0015] In some embodiments, the dispensing mechanism includes a first pushing component and at least one pair of first check components, the first storage component is located above the first check components, and a plurality of the trays are vertically stacked on the first check components; wherein,

[0016] Each of the first check components includes a first fixed seat and a first check element movably connected to the first fixed seat, the first check element having a first state of abutting the tray and a second state of releasing the tray;

[0017] The first pushing assembly includes a first pushing part movable along a second direction, the second direction being a vertical direction. When the first pushing part moves closer to the first storage component along the second direction, the first pushing part presses the first check valve to a second state so that a pallet near the first pushing part falls from the first storage component onto the first pushing part. When the first pushing part moves away from the first storage component along the second direction, the first pushing part carries the pallet that has fallen onto the first pushing part and moves it onto the conveying mechanism. The first check valve returns to the first state as the first pushing part moves and abuts against the next pallet.

[0018] In some embodiments, the first check member is rotatably connected to the first fixed base. The first check member has a first limiting portion for limiting the rotation angle of the first check member. When the first check member is in the first state, the first limiting portion abuts against the first fixed base to allow the first check member to support the tray of the first storage member. A first elastic member is provided between the first check member and the first fixed base. After the first check member loses the pressure of the first pushing portion, it can be reset to the first state under the action of the first elastic member.

The picking time is controlled after the pallet is separated from the conveying mechanism, which allows the conveying mechanism to operate without stopping during the picking process, thereby ensuring the continuity of conveying and effectively avoiding damage to the conveying mechanism caused by repeated start-stop operations. The implementation of this solution not only improves production efficiency, enabling the production line to operate continuously and stably and reducing downtime caused by equipment failure, but also extends the service life of the conveying equipment.

[0041] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0042] Please see Figure 1 , Figure 1 This is a schematic diagram of the operation of the feeding device in some embodiments of this application. Embodiments of this application provide a feeding device, including a mounting frame 10, which is provided with a feeding area 11, a material picking area 12 and a material unloading area 13. The feeding area 11 can stack multiple trays 60 containing materials, and the material unloading area 13 can receive the empty trays 60 remaining after the materials are picked up.

[0043] Please see Figure 2 and Figure 3 , Figure 2 yes Figure 1 A schematic diagram of the overall structure of the feeding device in this embodiment. Figure 3 yes Figure 1 A partial structural diagram of the feeding device in the embodiment is shown. The feeding device also includes a separation mechanism 40 and a conveying mechanism 30 disposed on the mounting frame 10. The conveying mechanism 30 is configured to sequentially convey the pallet 60 from the feeding area 11 to the picking area 12 and the unloading area 13 along a first direction. Specifically, the conveying mechanism 30 may include a motor assembly (not shown in the figure), a belt 32, and a plurality of tension pulleys 31. Each tension pulley 31 is rotatably connected to the mounting frame 10 and driven to rotate by the motor assembly. The belt 32 is drively connected to each tension pulley 31.

[0044] The separation mechanism 40 is disposed corresponding to the material handling area 12. The separation mechanism 40 is configured to drive the tray 60 to move along a second direction, which is not parallel to the first direction. Specifically, as follows... Figure 2 As shown, the first direction (X direction) can be a horizontal curved direction or a straight line direction, and the second direction (Y direction) can be a vertical direction perpendicular to the first direction.

[0045] The separating mechanism 40 can act on the pallet 60 conveyed to the picking area 12 to drive the pallet 60 to separate from the conveying mechanism 30 and wait for picking. After picking is completed, the empty pallet 60 returns to the conveying mechanism 30 of the picking area 12 under the action of the separating mechanism 40, so that the pallet 60 is conveyed to the unloading area 13 by the conveying mechanism 30.

[0046] By adopting the above scheme, the material is securely held on the pallet 60 at the initial stage of conveying, ensuring the stability of the material during the picking process. The picking time is controlled after the pallet 60 separates from the conveying mechanism 30, allowing the conveying mechanism 30 to operate without stopping during the picking process, thus ensuring the continuity of conveying and effectively avoiding damage to the conveying mechanism 30 caused by repeated start-stop cycles. The implementation of this scheme not only improves production efficiency, enabling the production line to operate continuously and stably and reducing downtime due to equipment failure, but also extends the service life of the conveying equipment.

[0047] Please see Figure 4 and Figure 5 , Figure 4 yes Figure 1 Top view of the feeding device in the embodiment. Figure 5 yes Figure 1 A schematic diagram of the tray structure in the embodiment. In some embodiments, the separating mechanism 40 includes a first positioning structure 41, and the tray 60 is provided with a positioning engagement structure 61 that is movably inserted into the first positioning structure 41. Specifically, when the separating mechanism 40 acts on the tray 60 in the picking area 12, the separating mechanism 40 can move the tray 60, and the first positioning structure 41 and the positioning engagement structure 61 are engaged; when the separating mechanism 40 separates from the tray 60 in the picking area 12, the tray 60 returns to the conveying mechanism 30 in the picking area 12, and the first positioning structure 41 and the positioning engagement structure 61 are disengaged.

[0048] For example, the first positioning structure 41 can be a positioning pin protruding from the separating mechanism 40, and the positioning mating structure 61 can be a positioning groove formed by the recess of the tray 60. In some implementation scenarios, the first positioning structure 41 can also be a positioning groove formed by the recess of the separating mechanism 40, and the positioning mating structure 61 can be a positioning pin protruding from the tray 60. This application only specifically describes the first positioning structure 41 as a positioning pin, wherein the positioning pin is designed as a stepped columnar structure, and the positioning groove presents a matching flared step, which facilitates the insertion and mating of the positioning pin and the positioning groove to achieve the horizontal positioning of the tray 60 in the material picking area 12.

[0049] Please see Figure 5 and Figure 6 , Figure 5 yes Figure 1 A schematic diagram of the tray structure in the embodiment. Figure 6 yes Figure 1 This is a structural schematic diagram of the pallet from another perspective in the embodiment. In some embodiments, the pallet 60 is provided with a second positioning structure 62, which is correspondingly disposed on opposite sides of the pallet 60 with the positioning mating structure 61. When multiple pallets 60 are stacked in the loading area 11 or unloading area 13, the second positioning structure 62 on one pallet 60 is inserted into and mated with the positioning mating structure 61 on the adjacent pallet 60. In conjunction with the aforementioned embodiment where the first positioning structure 41 is a positioning pin, the second positioning structure 62 can be a positioning pin with the same shape as the first positioning structure 41.

[0050] Please see Figure 2In some embodiments, the material picking area 12 is provided with a stop 121, which is fixed on the mounting frame 10. The separation mechanism 40 is configured to drive the pallet 60 to move between the conveying mechanism 30 and the stop 121, and when the pallet 60 is moved by the separation mechanism 40 to contact or approach the stop 121, the pallet 60 is controlled to stop moving along the original direction of movement to wait for material picking.

[0051] The pallet 60 includes a material-bearing area and a positioning area. The material-bearing area is used to hold materials. The second positioning structure 62 and the positioning mating structure 61 are set in the positioning area. At the same time, the stop 121 is set in correspondence with the positioning area of ​​the pallet 60 located in the material-picking area 12 to avoid interference with the material-picking mechanism during the material-picking process.

[0052] In automated production lines, the precise positioning of pallet 60 is a key factor in ensuring efficient and accurate material handling. By setting a stop 121, not only can the movement of pallet 60 in the picking area 12 along the second direction be effectively limited, but it can also ensure that pallet 60 can be precisely positioned when it moves to the picking position, thereby greatly improving the accuracy of material handling.

[0053] In some embodiments, the feeding device further includes a first position sensor for detecting the position of the pallet 60 in the feeding area 12, and the separating mechanism 40 is configured to drive the pallet 60 from the conveying mechanism 30 toward the stop 121 in response to the detection signal of the first position sensor.

[0054] Furthermore, the feeding device also includes a second position sensor for detecting the position of the tray 60 in the feeding area 12, and the separation mechanism 40 is configured to stop the tray 60 from continuing to move toward the stop member 121 in response to the detection signal of the second position sensor.

[0055] The first position sensor and the second position sensor can be proximity switches, photoelectric sensors, or magnetoelectric sensors, etc., without specific limitations here.

[0056] Please see Figure 7 , Figure 7 yes Figure 1 A schematic diagram of the separation mechanism in the embodiment. In some embodiments, the separation mechanism 40 includes a driving member 42, a guide member 43, and a moving member 44. The guide member 43 is arranged along a second direction, the moving member 44 is connected to the driving member 42, and the moving member 44 is slidably connected to the guide member 43. The first positioning structure 41 is fixed on the moving member 44. The tray 60 of the material picking area 12 is located between the moving member 44 and the stop member 121. The moving member 44 moves along the second direction to actively support the tray 60 of the material picking area 12, so that the first positioning structure 41 and the positioning mating structure 61 can be actively inserted to achieve horizontal positioning of the tray 60.

[0057] The driving component 42 includes, but is not limited to, linear driving mechanisms such as cylinders, hydraulic cylinders, and lead screws.

[0058] Please see Figure 1 and Figure 2 In some embodiments, the feeding area 11 is provided with a first storage component 111 and a sorting mechanism 20 corresponding to the first storage component 111. Multiple pallets 60 can be stacked on the first storage component 111, and the sorting mechanism 20 is used to sort the multiple pallets 60 one by one onto the conveying mechanism 30.

[0059] For example, the material distribution mechanism 20 includes a first push assembly 21 and at least one pair of first check assembly 22, a first storage component 111 is located above the first check assembly 22, and a plurality of trays 60 are vertically stacked on the first check assembly 22.

[0060] Please combine Figure 8 and Figure 9 , Figure 8 yes Figure 1 A schematic diagram of the structure of the first check valve component in the embodiment. Figure 9 yes Figure 1 A schematic diagram of the first check valve assembly from another perspective in the embodiment. Each first check valve assembly 22 includes a first fixing seat 223 and a first check valve member 221 movably connected to the first fixing seat 223. The first fixing seat 223 is fixedly connected to the mounting bracket 10. The first check valve member 221 has a first state of abutting the tray 60 and a second state of releasing the tray 60.

[0061] In some embodiments, the first check member 221 is rotatably connected to the first fixed base 223. The first check member 221 has a first limiting portion 2211, which limits the rotation angle of the first check member 221. When the first check member 221 is in the first state, the first limiting portion 2211 abuts against the first fixed base 223, and the first limiting portion 2211 provides a stable supporting force for the first check member 221, so that the first check member 221 can firmly support the tray 60 on the first storage member 111. A first elastic member 222 is provided between the first check member 221 and the first fixed base 223. After the first check member 221 loses the compression of the first pushing portion 211, it can return to the first state under the action of the first elastic member 222.

[0062] Furthermore, the first elastic element 222 includes, but is not limited to, elastic elements such as springs, sheet springs, and torsion springs, to provide the restoring force required for the first check element 221 to reset. When the first pushing part 211 presses against the first check element 221, the first check element 221 overcomes the elastic force of the first elastic element 222 and rotates to the second state. At this time, the first limiting part 2211 no longer abuts against the first fixed seat 223, and the tray 60 can fall from the first storage part 111 onto the first pushing part 211. When the first pushing part 211 moves away from the first storage part 111, the first check element 221 automatically resets to the first state under the action of the first elastic element 222, ready to abut against the next tray 60. This design not only ensures the orderly falling of the tray 60 but also improves the automation level of the entire feeding device.

[0063] Please see Figure 2 and Figure 10 , Figure 10 yes Figure 1 The first pushing assembly and the second pushing assembly are shown in the schematic diagram in the embodiment. The first pushing assembly 21 includes a first pushing part 211 that is movable along a second direction. When the first pushing part 211 moves closer to the first storage member 111 along the second direction, the first pushing part 211 presses the first check member 221 to a second state so that a tray 60 close to the first pushing part 211 falls from the first storage member 111 onto the first pushing part 211. When the first pushing part 211 moves away from the first storage member 111 along the second direction, the first pushing part 211 carries the tray 60 that has fallen onto the first pushing part 211 and moves it to the conveying mechanism 30. The first check member 221 resets to the first state as the first pushing part 211 moves and abuts against the next tray 60.

[0064] The first pushing assembly 21 also includes a first driving part 212 and a first guide rail 213. The first guide rail 213 is disposed on the mounting bracket 10 along the second direction. The first driving part 212 is connected to the first pushing part 211 to drive the first pushing part 211 to move along the second direction. The first driving part 212 includes, but is not limited to, linear driving mechanisms such as cylinders, hydraulic cylinders, and lead screws.

[0065] Please combine Figure 3 Furthermore, the first pushing part 211 is provided with a third positioning structure 2111, which is movably inserted into the positioning mating structure 61 on the pallet 60. The third positioning structure 2111 can be a positioning pin with the same shape as the first positioning structure 41. When the first pushing part 211 carries the pallet 60 and moves along the second direction, the third positioning structure 2111 is inserted into the positioning pallet 60 structure on the pallet 60 to ensure the stability of the pallet 60 during movement.

[0066] Please refer to the previous document. Figure 1 and Figure 2In some embodiments, the unloading area 13 is provided with a second storage component 131 and a unloading mechanism 50 corresponding to the second storage component 131. Multiple pallets 60 can be stacked on the second storage component 131. The unloading mechanism 50 is used to transfer the pallets 60 conveyed to the unloading area 13 to the second storage component 131.

[0067] Each of the second check components 52 includes a second fixed seat (not shown in the figure) and a second check member 521 movably connected to the second fixed seat. The second fixed seat is fixedly connected to the mounting bracket 10. The second check member 521 has a third state of abutting the tray 60 and a fourth state of releasing the tray 60.

[0068] Please combine Figure 10 The second pushing assembly 51 includes a second pushing part 511 movable in the second direction. When the second pushing part 511 moves close to the second storage member 131, the second pushing part 511 can hold the empty pallet 60 located in the unloading area 13 on the conveying mechanism 30 and drive the empty pallet 60 to squeeze the second check member 521 to the fourth state during the movement. After the empty pallet 60 passes through the second check member 521 and moves above the second check member 521, the second check member 521 resets to the first state and abuts against the empty pallet 60 on the second check member 521.

[0069] It should be noted that the second pushing part 511 does not abut against the second check member 521. When the second pushing part 511 holds the empty pallet 60, a gap is maintained between the edge of the second pushing part 511 and the empty pallet 60, so that the empty pallet 60 can squeeze the second check member 521 and move above the second check member 521. After the second check member 521 moves above the second check member 521, the second check member 521 can reset and insert into the gap between the second pushing part 511 and the empty pallet 60, thereby supporting the empty pallet 60 located above the second check member 521.

[0070] The second pushing assembly 51 also includes a second driving part 512 and a second guide rail 513. The second guide rail 513 is disposed on the mounting bracket 10 along a second direction. The second driving part 512 is connected to the second pushing part 511 to drive the second pushing part 511 to move along the second direction. The second driving part 512 includes, but is not limited to, linear driving mechanisms such as cylinders, hydraulic cylinders, and lead screws.

[0071] It is understandable that the specific structures of the second push component 51 and the second check component 52 can be set with reference to the first push component 21 and the first check component 22, and will not be described in detail here.

[0072] Please combine Figure 3The second pushing part 511 is provided with a fourth positioning structure 5111, which is movably inserted into the positioning mating structure 61 on the pallet 60. The fourth positioning structure 5111 can be a positioning pin with the same shape as the first positioning structure 41. When the second pushing part 511 carries the empty pallet 60 and moves along the second direction, the fourth positioning structure 5111 is inserted into the positioning pallet 60 structure on the pallet 60 to ensure the stability of the pallet 60 during movement.
