[0022] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments, so that the advantages and features of this utility model can be more easily understood by those skilled in the art. Obviously, the embodiments described in this application are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0023] See Figures 5 to 8 The illustrated feeding device includes a feeding mechanism 100 and a multi-functional workpiece receiving device 300. The feeding mechanism 100 is used to transport and transfer workpieces 200, and the multi-functional workpiece receiving device 300 is used to receive the workpieces 200 transferred by the feeding mechanism 100. See also... Figures 1 to 4 The multifunctional workpiece receiving device 300 shown includes a receiving module 1 and a transfer mechanism 2. The receiving module 1 includes two receiving racks 11 arranged parallel to each other along a second direction. The receiving racks 11 extend along a first direction, which is perpendicular to the second direction. At least one receiving rack 11 is movably arranged along the second direction. The transfer mechanism 2 includes a transfer member 21 for transferring workpieces 200 along the first direction. The transfer member 21 is disposed on the upper part of the receiving racks 11.

[0024] In this embodiment, the workpiece receiving device has a first mode and a second mode. In the first mode, see... Figure 5 , Figure 6 As shown, two sets of receiving racks 11 are spaced apart along a second direction, forming a receiving space 110 between the two sets of receiving racks 11 to accommodate the feeding mechanism 100. The receiving module 1 has an opening 101 on one side along a first direction for entering and exiting the receiving space 110. The upper surfaces of the transmission components 21 on the two receiving racks 11 together form a bearing surface for receiving the workpiece 200. In the first mode, the feeding mechanism 100, loaded with the workpiece 200, enters the receiving space 110 through the opening 101. During the entry into the receiving space 110, the workpiece 200 remains above the transmission component 21. After the feeding mechanism 100 enters the receiving space 110, it drives the workpiece 200 downwards, causing the workpiece 200 to be supported on the bearing surface. After the workpiece 200 is supported on the bearing surface, the workpiece receiving device completes the receiving of the workpiece 200, the feeding mechanism 100 completes the transfer of the workpiece 200, the feeding mechanism 100 can detach from the workpiece 200 and can leave the accommodating space 110 from the opening 101, thereby leaving the receiving module 1.

[0025] In this embodiment, in the second mode, see [link / reference]. Figure 7 , Figure 8 As shown, a transmission channel 120 extending along a first direction is formed above the two transmission components 21, and an inlet 102 of the transmission channel 120 is formed on one side of the receiving module 1 along the first direction. In the second mode, the feeding mechanism 100 does not enter between the two receiving racks 11. The feeding mechanism 100 carrying the workpiece 200 moves to one side of the receiving module 1, specifically, the feeding mechanism 100 moves along the first direction to the side where the inlet 102 is located. Then the workpiece 200 enters the transmission channel 120 from the inlet 102, and under the action of the transmission components 21, the workpiece 200 is completely transferred to the receiving module 1, thus completing the transfer and reception of the workpiece 200. After that, the feeding mechanism 100 can leave the receiving module 1.

[0026] In this embodiment, see Figure 1 , Figure 2 As shown, the transmission component 21 includes a plurality of rollers 211 spaced apart along a first direction. The rollers 211 are rotatably mounted on the receiving frame 11 about a rotation center line extending along a second direction. The rolling motion of the rollers 211 drives the workpiece 200 to move along the first direction. The transmission mechanism also includes a drive module for driving the rollers 211 to rotate. In this embodiment, the drive module includes a power roller 22 capable of rotating about its own axis and a linkage component (not shown in the figure) disposed between the power roller 22 and the rollers 211. When the transmission mechanism 2 is working, the power roller 22 drives the rollers 211 to rotate, and the rollers 211 drive the workpiece 200 above to move along the first direction.

[0027] In some embodiments, the transmission element 21 includes a transmission belt.

[0028] In some embodiments, the linkage includes a chain and a sprocket; in other embodiments, the linkage includes a timing pulley and a timing belt.

[0029] In this embodiment, each receiving rack 11 is equipped with a drive module, that is, each receiving rack 11 is equipped with a power roller 22 and a linkage component. With this configuration, the transmission components 21 on the two receiving racks 11 can not only operate synchronously, but also, for some workpieces 200 with special structures, drive the transmission components 21 on the two receiving racks 11 to transmit at different rhythms, making the workpiece receiving device more adaptable.

[0030] In this embodiment, since at least one receiving rack 11 can move along the second direction, the distance between the two receiving racks 11 is adjustable. This not only allows for the adaptation to workpieces 200 of different sizes, but also allows for the adjustment of the size of the accommodating space 110 in the first mode to accommodate feeding mechanisms 100 of different sizes. In the second mode, the width of the transmission channel 120 can be adjusted.

[0031] In this embodiment, the workpiece receiving device includes a guide rail 3 extending along the second direction, and a sliding member 12 is fixedly provided on the receiving rack 11. The sliding member 12 is slidably connected to the guide rail 3, thereby realizing the sliding of the receiving rack 11 along the second direction, and providing guidance for the sliding of the receiving rack 11 through the cooperation of the sliding member 12 and the guide rail 3.

[0032] In this embodiment, a wheel assembly 13 is provided at the lower part of the receiving rack 11, which also enables the receiving rack 11 to be movable. Specifically, see Figure 1 As shown, the wheel assembly 13 and the slider 12 are spaced apart along the length of the receiving frame 11, which can better maintain the stability of the receiving frame 11. In this embodiment, the slider 12 and the wheel assembly 13 are located at the lower part of the receiving frame 11.

[0033] In this embodiment, see Figure 1 As shown, the movable receiving rack 11 has two guide rails 3 arranged in parallel below it. Two sets of sliding members 12 are arranged in parallel at the bottom of the receiving rack 11, and each set of sliding members 12 slides in cooperation with one of the two guide rails 3. Specifically, multiple sliding members 12 spaced apart along the second direction form a group, which further improves the stability of the receiving rack 11's sliding motion.

[0034] In this embodiment, both receiving racks 11 are slidably arranged along the first direction. Each receiving rack 11 has a guide rail 3 below it, and each receiving rack 11 has a sliding member 12 and a wheel assembly 13 at its lower part. Both receiving racks 11 are movable, which makes the adjustment range of the receiving module 1 wider and the flexibility higher.

[0035] In this embodiment, the two receiving racks 11 have similar structural configurations. Specifically, the receiving module 1 has a virtual symmetry plane that extends along a first direction and also extends along a vertical direction. The structures of the two receiving racks 11 are symmetrically arranged relative to the virtual symmetry plane.

[0036] In this embodiment, the workpiece receiving device includes a positioning mechanism 4, which includes a clamping member 41. The clamping member 41 is movably disposed on the receiving rack 11 along a second direction, and the clamping members 41 on the two receiving racks 11 can be disposed relatively close to each other. Specifically, the clamping member 41 has a clamping portion 411, which is located above the transfer member 21 in the vertical direction. When the workpiece 200 is transferred to the transfer member 21, the clamping portions 411 on the two receiving racks 11 move relatively close to each other along the second direction, thereby clamping the workpiece 200 and positioning it along the second direction.

[0037] In this embodiment, the positioning mechanism 4 further includes a first positioning element 42, which is disposed on the upper part of the receiving rack 11 and on the path of the conveying member 21 for conveying the workpiece. In some embodiments, the first positioning element 42 is located between two adjacent rollers 211. In this embodiment, the power roller 22 is located on the side away from the entrance of the conveying channel 120 along the first direction, and the first positioning element 42 is located between the power roller 22 and the adjacent roller 211. When positioning the workpiece 200, the conveying member 21 conveys the workpiece 200 along the first direction until the workpiece 200 contacts the first positioning element 42, thereby achieving the positioning of the workpiece 200 in the first direction.

[0038] In this embodiment, the positioning mechanism further includes a second positioning element 43, which is disposed between the two receiving racks 11 along a second direction and along the conveying path of the workpiece 200 along a first direction. The second positioning element 43 has the same function as the first positioning element 42, both used to position the workpiece 200 along the first direction. In some embodiments, the receiving device is provided with only one of the first positioning element 42 and the second positioning element 43.

[0039] In this embodiment, the first positioning member 42 has a first positioning surface 421, which extends along the vertical direction and a second direction. Positioning is achieved when the workpiece 200 abuts against the first positioning surface 421. The second positioning member 43 has a second positioning surface 431, which extends along the vertical direction and a second direction. Positioning is achieved when the workpiece 200 abuts against the second positioning surface 431. In this embodiment, the first positioning surface 421 and the second positioning surface 431 are located in the same plane extending along the vertical direction and a second direction. In other embodiments, the positions of the first positioning surface 421 and the second positioning surface 431 can be adjusted according to the different side structures of the workpiece 200.

[0040] In this embodiment, the receiving rack 11 is provided with a locking pin 14, which is movably arranged along its own axial direction. The locking pin 14 is used to lock the receiving rack 11 to maintain its stability. Specifically, a locking hole that cooperates with the locking pin 14 is provided on the machine base or ground where the workpiece receiving device is provided. The locking rack 11 is locked by driving the locking pin 14 into the locking hole. In this embodiment, there are multiple locking holes spaced apart along the second direction, which can lock the receiving rack 11 in different positions.

[0041] In this embodiment, the receiving rack 11 is provided with side stops 15, which are arranged along the second direction on one side of the conveying member 21. The two conveying members 21 are located between the side stops 15 on the two receiving racks 11 along the second direction. The side stops 15 on both sides can play a limiting role. In the first mode, they can guide the workpiece 200 to fall onto the bearing surface. In the second mode, the conveying channel 120 is located between the side stops 15 on the two receiving racks 11, and the side stops 15 on both sides can prevent the workpiece 200 from leaving the conveying channel 120 along the second direction.

[0042] In some embodiments, in a first mode, the two receiving racks 11 have a first distance along a second direction. In a second mode, the two receiving racks 11 are close to each other along the second direction, and the two receiving racks 11 have a second distance along the second direction, the second distance being smaller than the first distance.

[0043] In some embodiments, in the second mode, the second spacing is less than the width of the feeding mechanism 100, and the feeding mechanism 100 cannot enter between the two receiving racks 11. See also Figure 4 The workpiece receiving device shown has two receiving racks 11 brought together in a second mode.

[0044] In this embodiment, the feeding mechanism 100 has a support surface for supporting the workpiece, and the feeding device has a first feeding state and a second feeding state. In the first feeding state, the workpiece receiving device is in a first mode, the feeding mechanism 100 is located in the accommodating space 110, and the support surface is located above the transmission member 21. In this state, by driving the feeding mechanism 100 to move the support surface downward, the workpiece 200 falls down to the top of the bearing surface, thus completing the transfer of the workpiece 200. In the second feeding state, the feeding mechanism 100 is located on one side of the receiving rack 11 along the first direction, specifically on the side of the inlet 102 of the transmission channel 120, and the support surface is flush with the upper surface of the transmission member 21. In the second feeding state, the support surface and the upper surface of the transmission member 21 can be directly connected or connected at a certain distance, so that the workpiece 200 located on the support surface can directly enter the transmission channel 120 from the inlet 102, and the workpiece 200 can be transferred to the top of the transmission member 21.

[0045] See Figure 5 , Figure 6 As shown, the feeding mechanism 100, applicable to the first feeding state, has a lifting mechanism that can drive the support surface to move up and down, thereby lifting the workpiece 200 upwards to prevent the workpiece 200 from disengaging from the receiving module 1 during the feeding mechanism 100's entry into the receiving space 110. Simultaneously, when the feeding mechanism 100 enters the receiving space 110, the lifting mechanism can drive the support surface downwards and transfer the workpiece 200 onto the transfer module 1, specifically, above the transfer member 21.

[0046] In this embodiment, after the workpiece receiving device receives the workpiece 200 in the first mode, the transmission member 21 drives the workpiece 200 to move along the first direction, and finally drives the workpiece 200 to contact the first positioning member 42 or the second positioning member 43, thereby achieving positioning in the first direction. Then, the clamping members 41 on both sides clamp the workpiece 200 to achieve positioning in the second direction.

[0047] See Figure 7 , Figure 8 As shown, the feeding mechanism 100, applicable to the second feeding device, may be equipped with a power module capable of driving the workpiece 200 to move. After the feeding mechanism 100 moves to a designated position, the power module drives the workpiece 200 into the transmission channel 120, and then, with the cooperation of the power module and the transmission component 21, the workpiece 200 is completely transferred to the receiving module 1. Alternatively, the feeding mechanism 100 may not have a power module, but instead uses other external handling mechanisms to transfer the workpiece 200.

[0048] In this embodiment, when the workpiece receiving device receives the workpiece 200 in the second mode, the workpiece 200 can move directly along the transmission channel 120 to contact the first positioning member 42 or the second positioning member 43 to achieve positioning in the first direction. Then, the clamping members 41 on both sides position the workpiece 200 in the second direction.

[0049] In this embodiment, see Figure 5 , Figure 7 As shown, the feeding mechanism 100 can employ intelligent robots such as AGVs. (See also...) Figure 8 As shown, the feeding mechanism 100 can also be a manually driven trolley.

[0050] In summary, the workpiece receiving device of this embodiment has a first mode and a second mode. In the first mode, the feeding mechanism 100 can enter the accommodating space 110 located between the two receiving racks 11 and transport the workpiece 200 downwards to the bearing surface. In the second mode, the feeding mechanism 100 is located on one side of the receiving module 1, and the workpiece 200 directly enters the transmission channel 120 from the inlet 102 and is transmitted to the receiving module 1 along the transmission channel 120. In the first mode, the feeding mechanism 100 directly enters between the two receiving racks 11 for feeding. Compared with the second mode, this avoids the feeding mechanism 100 occupying the space on one side of the receiving module 1, which could cause equipment blockage and affect the operation of other devices. In the second mode, feeding is more direct and faster, and the working mode of the workpiece receiving device is no longer singular. Different modes can be selected according to different scenarios to improve efficiency. At the same time, at least one receiving rack 11 of the receiving module 1 is movable, and the distance between the two receiving racks 11 can be adjusted, thereby adapting to workpieces 200 of different sizes, and the workpiece receiving device has a wider range of applications.

[0051] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
