Description

Technical Field

[0001] The present invention relates to a material conveying, and in particular to a disk separating mechanism and a feeding device for separating stacked disks. Background Art

[0002] For some electronic devices such as memory modules, during the production process, relevant devices are first placed in trays, and then the trays are stacked together and conveyed to relevant production lines for production. During use, it is often necessary to separate them individually, and then convey them one by one to corresponding positions for production operations, and then stack and convey the empty trays after grasping the devices. Therefore, a corresponding tray separating device needs to be provided at the front end of the production line.

[0003] Referring to Chinese Patent CN201810312511.5, a disk separating mechanism and a feeding device are disclosed, which can sequentially separate trays and fold the empty trays after the devices are grasped. However, in order to facilitate feeding, a storage bin needs to be provided. After the material rack runs out of materials, the conveying device in the storage bin is controlled to push the stack of trays from the storage bin to the feeding bin. The feeding area occupies too much space. And in order to save space, the storage bin is located below the stacking component, which is inconvenient for discharging materials, and it is very difficult to use a manipulator to put materials into the storage bin, and manual operation is often required.

[0004] Referring to Chinese Patent CN201821636278.8, a tray automatic separating mechanism is disclosed, which can sequentially separate trays. If this material rack is used in a corresponding production line, in order to facilitate feeding, enough space needs to be left above the separating mechanism, resulting in too much space occupied by the feeding area. If the tray automatic separating mechanism is placed below other workstations, it will make feeding difficult.

[0005] Therefore, there is an urgent need for a tray separating device and a feeding device that occupy a small floor space and are convenient for feeding. Summary of the Invention

[0006] The object of the present invention is to provide a tray separating device and a feeding device, the material rack of which can be slid out for feeding, which is convenient for feeding and saves space.

[0007] To achieve the above object, the present invention discloses a tray separation device for separating stacked trays, which includes a sliding frame, a mounting frame, a material separation device, a bearing table, and a lifting drive mechanism. The mounting frame is located at the material separation station. The sliding frame can slide relative to the mounting frame between the material separation station and the feeding station. A tray placement area is formed on the sliding frame. The material separation device includes a material separation block movably installed on the sliding frame and capable of extending into the tray placement area to carry the tray, and a material separation drive part installed on the mounting frame and corresponding to the position of the material separation block. A engaging component that cooperates with each other is provided between the material separation block and the material separation drive part. A return spring is also connected between the material separation block and the sliding frame. The return spring provides an elastic force for the material separation block to extend into the tray placement area, so that when the sliding frame is at the feeding station, the material separation drive part is separated from the material separation block and the material separation block remains in the extended carrying state. When the sliding frame slides from the feeding station to the material separation station, the material separation drive part is engaged with the material separation block and drives the material separation block to perform a telescopic action to carry or release the tray. The bearing table is installed at the material separation station and is located below the tray placement area. The lifting drive mechanism drives the bearing table to perform a lifting action.

[0008] Preferably, the tray separation device further includes a feeding drive part, which is installed on the mounting frame and can drive the sliding frame to slide between the material separation station and the feeding station. This solution enables the sliding frame of the tray separation device to automatically pop out and return, which is suitable for automatic loading and unloading.

[0009] Preferably, the engaging component includes an engaging part connected to the material separation block and an engaging drive part connected to the output part of the material separation drive part and capable of engaging with the engaging part. An engaging edge extending along the sliding direction of the sliding frame and facing the material placement area direction is formed on the engaging part. The engaging drive block can gradually extend into the inner side of the engaging edge and engage with the engaging edge as the sliding frame slides towards the material separation station.

[0010] Preferably, a return spring is also connected between the material separation block and the sliding frame. The return spring provides an elastic force for the material separation block to extend into the tray placement area, ensuring that the material separation block remains in the extended carrying state under normal conditions and preventing accidents from causing the tray to fall.

[0011] Preferably, the material separation block is slidably installed on the sliding frame and can perform a telescopic action relative to the tray placement area. The material separation drive part is a telescopic drive part.

[0012] Among them, the material separation drive part includes a telescopic cylinder, and the telescopic cylinder drives the material separation block to perform a telescopic action relative to the tray placement area. Of course, the material separation drive part can also be other telescopic drive parts.

[0013] The present invention also discloses a feeding device, characterized in that it includes a tray separation device, a stacking device, a conveying device, a clamping device, a clamping station, and a stacking station. The tray separation device is as described in any one of the above. The conveying device includes conveyor belts located on two opposite sides of the carrier table, and at least a part of the conveyor belts is within the coverage area below the material placement area, so that when the carrier table carrying the tray descends, the tray can be carried on the conveyor belts accordingly. The conveying device can drive the tray to move from the material separation station to the clamping station and the stacking station in sequence. The clamping device is located at the clamping station and fixes the tray, and the stacking device is located at the stacking station and stacks the trays.

[0014] Preferably, the feeding device further includes a lifting station, which is adjacent to the material separation station and located at the rear of the material separation station. The clamping station is located directly above the lifting station, and the stacking station is located directly above the material separation station. The conveying device sequentially moves the tray from the material separation station to the lifting station, from the lifting station to the clamping station, and from the clamping station to the stacking station. The multiple stations are arranged vertically, saving space.

[0015] Preferably, the clamping station is located at the rear of the stacking station. The conveying device includes a transverse conveying mechanism, which includes a transverse driving part, a conveying support, and a pushing part rotatably installed on the conveying support. The transverse driving part drives the conveying support to move in the front-rear direction, and the conveying support drives the pushing part to move between the clamping station and the stacking station in the front-rear direction. Moreover, the pushing part can push the tray at the clamping station to move from the clamping station to the stacking station. More preferably, the pushing part includes a push block located at one end of the rotating shaft of the pushing part and a counterweight block located at the other end of the rotating shaft. The counterweight block can drive the push block to rise to the pushing position corresponding to the tray at the clamping station. The conveying support forms a limiting part adjacent to the push block and a clearance groove adjacent to the counterweight block on the side facing away from the stacking station. The limiting part restricts the rotation position of the pushing part to prevent the pushing part from rotating to a position below the pushing position on the side away from the stacking station, and the clearance groove provides an accommodation space for the counterweight block so that the push block can rotate to a position below the pushing position under the action of the force towards the stacking station. This solution enables the transverse conveyor belt to drive the tray to move towards the stacking station, while the lifting conveyor belt can simultaneously drive a new tray to rise to the clamping station for clamping. When the transverse conveyor belt drives the pushing part to return, the pushing part can rotate upward to move below the clamping station and return to the initial position from below the tray.

[0016] Preferably, the stacking device includes a stacking mounting frame forming a stacking station, a stacking driving part, a stacking support, a plurality of support blocks mounted on the stacking mounting frame and located at at least two opposite edges of the stacking station, and elastic members mounted between the support blocks and the stacking mounting frame. The support blocks can rotate relative to the stacking mounting frame, and can rotate downward to a lower limit position to extend into the stacking station and support the tray, and can rotate upward to exit the stacking station. The elastic members provide an elastic force for the support blocks to extend into the stacking station. The stacking support is mounted below the stacking station and supports the tray at the stacking station, and the stacking support is staggered from the support blocks in position. The stacking driving part is connected to the stacking support and drives the stacking support to lift, so as to lift the tray at the stacking station above the support blocks. This solution does not require a driving source to control the rotation of the support blocks. When the trays are stacked and lifted, the trays can push the support blocks to make the support blocks rotate out of the stacking station. When the trays are lifted above the support blocks, the support blocks can reset under the elastic force of the elastic members to carry the trays, thereby realizing the stacking of the trays.

[0017] Compared with the prior art, the operating device - the material distribution device on the material rack of the present invention is divided into a separated material distribution part and a driving part. The material rack is divided into a sliding rack and a mounting rack. The material distribution part is mounted on the sliding rack, and the driving part is mounted on the mounting rack. And through the engaging component, the material distribution part and the driving part can be engaged together as the sliding rack returns to the material distribution station, so that the driving part does not need to move during feeding, and the driving source of the driving part will not interfere with the frame of the production line due to the movement of the material rack and cause failures. The above structure enables the sliding rack to be set as a pull-out structure, and the sliding rack can slide relative to the mounting rack between the feeding station and the material distribution station. During feeding, the sliding rack can be pulled out to the feeding station, which is convenient for feeding and occupies a small floor space. Other devices and stations can be set above the material distribution station, and the space setting is flexible. Description of the Drawings

[0031] To describe in detail the technical content, structural features, achieved purposes and effects of the present invention, the following is a detailed description in conjunction with the implementation modes and with reference to the accompanying drawings.

[0032] Refer to Figure 1 and Figure 2 The present invention discloses a feeding device 100, including a tray separation device 10, conveying devices (20, 30, 40), a stacking device 50, a clamping device 60, a loading station 101, a material separation station 102, a clamping station 104 and a stacking station 105. The tray separation device 10 loads the stacked trays 200 at the loading station 101 and separates the trays 200 one by one at the material separation station 102. The conveying devices (20, 30, 40) convey the trays from the material separation station 102 to the clamping station 104. The clamping device 60 clamps and fixes the trays 200 for the relevant devices to grab the electronic components on the trays 200. After the grabbing is completed, the conveying devices (20, 30, 40) convey the empty trays to the stacking station 105, and the stacking device 50 stacks the trays 200 in sequence.

[0033] To save space and facilitate the grasping of electronic devices, the stacking station 105 is located directly above the material separation station 102, and the clamping station 104 is located on the side of the stacking station 105 and arranged in parallel with the stacking station 105. Therefore, a lifting station 103 is added directly below the clamping station 104. The conveying devices (20, 30, 40) need to convey the tray 200 from the material separation station 102 to the lifting station 103, and then from the lifting station 103 to the clamping station 104. Of course, the conveying device is not limited to the above-mentioned conveying device. The lifting station 103 is a transfer station formed to convey the tray 200 to the clamping station 104. The tray 200 can be directly conveyed from the material separation station 102 to the clamping station 104 through a conveying device, omitting the lifting station 103, or the tray 200 can be conveyed to the clamping station 104 through other conveying devices.

[0034] Reference Figures 3 to 5 , the tray separating device 10 includes a mounting frame 11, a sliding frame 12, a material separating device 14, a carrying platform 16, and a lifting drive mechanism 17. The mounting frame 11 is located at the material separation station 102. The sliding frame 12 can slide relative to the mounting frame 11 between the material separation station 102 and the feeding station 101. A material placement area is formed on the sliding frame 12, and the material placement area is used to place the tray stack. The material separating device 14 includes a separating block 141 movably mounted on the sliding frame 12 and capable of extending into the material placement area to carry the tray 200, and a separating drive part 142 mounted on the mounting frame 11 and corresponding to the position of the separating block 141. Among them, a engaging component (144, 145) that cooperates with each other is provided between the separating block 141 and the separating drive part 142, so that when the sliding frame 12 is located at the material separation station 102, the separating drive part 142 is engaged and connected with the separating block 141, and the separating drive part 142 drives the separating block 141 to perform telescopic movement to carry and release the tray 200. The carrying platform 16 is mounted at the material separation station 102 and is located below the tray placement area, and the lifting drive mechanism 17 drives the carrying platform 16 to perform lifting movement to carry the tray 200.

[0035] Reference Figure 4 , in this embodiment, the end of the separating block 141 is wedge-shaped. In this embodiment, the separating block 141 is slidably mounted on the sliding frame 12, and the separating drive part 142 is a telescopic drive part.

[0036] Reference Figure 6 and Figure 7, during operation, the sliding carriage 12 slides out of the mounting frame 11 and moves to the loading station 101 to load the stack of trays. The material separating driving part 142 is separated from the material separating block 141, and the material separating block 141 remains in the extended and bearing state. After the loading of 1 is completed, the sliding carriage 12 returns from the loading station 10 to the mounting frame 11 and moves to the material separating station 102. The material separating block 141 and the material separating driving part 142 are engaged with each other so that the material separating driving part 142 can drive the material separating block 141 to act. The sensor 201 detects that the stack of trays is in place to start the material separating work: the lifting driving mechanism 17 controls the lifting platform 16 to rise to bear the stack of trays. The material separating driving part 142 pulls the material separating block 141 away from the material placement area, so that the material separating block 141 exits the material placement area to release the stack of trays, and the stack of trays falls onto the lifting platform 16. The lifting driving mechanism 17 controls the lifting platform 16 to descend a preset distance (approximately the thickness of one tray), so that the bottom tray of the stack of trays is lower than the height where the material separating block 141 is located. The material separating driving part 142 acts to make the material separating block 141 extend into the material placement area. At this time, the material separating block 141 extends below the second-to-last tray (between the last tray and the second-to-last tray). The lifting driving mechanism 17 drives the lifting platform 16 to descend to the initial position, and the second-to-last tray is carried on the material separating block 141, that is, the new stack of trays is carried on the material separating block 141, and the last tray is separated out.

[0037] Reference Figure 6 and Figure 7 , the conveying device includes a conveyor belt 20. The conveyor belt 20 includes a first part 21 located on two opposite sides of the lifting platform 16. The two opposite sides of the first part 21 are within the coverage range below the material placement area. When the lifting platform 16 carrying the last tray 200 descends, the tray 200 can be carried on the first part 21 and separated from the lifting platform 16 accordingly. At this time, the conveyor belt 20 operates, and the first part 21 can drive the tray 200 thereon to be conveyed out from the material separating station 102.

[0038] Reference Figure 5 , a sliding assembly that cooperates with each other is provided between the sliding carriage 12 and the mounting frame 11 to enable the sliding carriage 12 to slide relative to the mounting frame 11. The sliding assembly includes a slide rail 151 and a slide piece 152.

[0039] Reference Figures 3 to 5, the material distribution block 141 is arranged at the edge of the material placement area, and is slidably installed on the sliding frame 12 through the sliding track 143 and can telescopically slide relative to the material placement area. There are multiple material distribution blocks 141, which are distributed on at least two opposite sides of the material placement area. In this embodiment, there are four material distribution blocks 141, which are respectively arranged at both ends of the left and right sides of the material placement area (near the four corners of the material placement area). The loading station 101 and the material distribution station 102 are arranged side by side. In this solution, the sliding frame 12 slides horizontally relative to the mounting frame 11. Of course, there may also be a certain height difference or a certain angle between the loading station 101 and the material distribution station 102. At this time, the sliding frame 12 slides relative to the mounting frame 11 along the arc track.

[0040] Reference Figure 3 and Figure 4 , the material placement area is relatively surrounded by a plurality of limiting blocks 121 vertically arranged on the sliding frame 12, and limiting grooves with opposite positions are formed on the limiting blocks 121. In this embodiment, the limiting grooves of the four limiting blocks 121 are opposite to each other and surround the material placement area.

[0041] In this embodiment, the material distribution driving part 142 includes a telescopic cylinder, and the telescopic cylinder drives the material distribution block 141 to telescopically move relative to the material placement area. Of course, other telescopic driving parts can also be used to replace the telescopic cylinder.

[0042] Reference Figures 3 to 5 , the engaging component includes an engaging piece 144 connected to the material distribution block 141 and an engaging driving block 145 connected to the output piece of the material distribution driving part 142 and capable of being engaged with the engaging piece 144. An engaging edge 1441 extending along the sliding direction of the sliding frame 12 and facing the material placement area direction is formed on the engaging piece 144 (as Figure 4 shown), the engaging driving block 145 can extend into the inside of the engaging edge and be engaged with the engaging edge 1441. Among them, the engaging driving block 145 can gradually extend into the inside of the engaging edge 1441 to be engaged with the engaging edge 1441 as the sliding frame 12 slides towards the material distribution station, and the material distribution driving part 142 drives the engaging driving block 145 to act to drive the material distribution block 141 to move relative to the material placement area through the engaging piece 144, so that the material distribution block 141 can extend into or withdraw from the material placement area.

[0043] Preferably, a return spring (not shown in the figure) is further connected between the material distribution block 14 and the sliding frame 12, and the return spring provides an elastic force for the material distribution block 14 to extend into the material placement area. Of course, a combination of a clamping groove and a clamping slider extending into the clamping groove can also be used to replace the clamping member 144 and the clamping driving block 145. At this time, the material distribution driving part 142 directly drives the telescopic movement of the material distribution block 141 through the clamping assembly composed of the clamping groove and the clamping slider.

[0044] Reference Figure 5 , on the side of the clamping member 143 away from the material placement area, a clamping area extending along the sliding direction of the sliding frame 12 is formed. The clamping area has an opening 146 on the side facing the material distribution station 102, and the clamping edge is formed on the side of the clamping area facing the material placement area. As the sliding frame slides towards the material distribution station, the clamping driving block 145 can extend into the clamping area along the opening 146.

[0045] Reference Figure 5 , in order to further realize automatic production, the tray separation device 10 further includes a feeding driving part 13. Reference Figure 4 and Figure 5 , the feeding driving part 13 is installed on the mounting frame 11 and can drive the sliding frame 12 to slide between the material distribution station 102 and the feeding station 101. Among them, the feeding driving part 13 includes a rotation driving part 131, a meshing gear 132 and a straight rack 133. The straight rack 133 is installed on the sliding frame 12 and has a plurality of teeth meshing with the meshing gear 132. The rotation driving part 131 is connected to the meshing gear 132 and drives the meshing gear 132 to rotate, thereby driving the straight rack 133 to move. The straight rack 133 drives the sliding frame 12 to slide between the material distribution station 102 and the feeding station 101. Among them, a limiting component for limiting the movement of the straight rack 133 is further provided between the sliding frame 12 and the mounting frame 11.

[0046] Continue to refer to Figure 6 and Figure 7 , the conveyor belt 20 further includes a second part 22. The front end of the second part 22 is connected to the end of the first part 21 and conveys the trays 200 output by the first part 21 to the lifting station 103.

[0047] Reference Figure 2 and Figure 8, the conveying device includes a lifting mechanism 30. The lifting mechanism 30 includes a first lifting driving part 31, a lifting conveyor belt 32, and a first support member 33 connected to the lifting conveyor belt 32 and supporting the tray 200. The first lifting driving part 31 drives the lifting conveyor belt 32 to move. The lifting conveyor belt 32 is arranged in the vertical direction and drives the first support member 33 to move between the lifting station 103 and the clamping station 104. When the second part 22 conveys the tray 200 to the lifting station 103, the first support member 33 is located below the tray 200. The first lifting driving part 31 drives the lifting conveyor belt 32 to rotate forward, and the lifting conveyor belt 32 drives the first support member 33 to rise to lift the tray 200 at the lifting station 103 to the clamping station 104.

[0048] Reference Figure 8 , the clamping device 60 includes a first clamping unit 61 arranged on the left and right sides of the clamping station 104, a second clamping unit 62 arranged on the front side of the clamping station 104, and a third clamping unit 63 arranged on the rear side of the clamping station 104. The first clamping unit 61 includes a first clamping driving part 611 and a first clamping block 612. The first clamping blocks 612 of the two first clamping units 61 are arranged oppositely and can clamp the tray 200 at the clamping station 104. And the first clamping block 612 is stepped. When the stepped side surface of the first clamping block 612 clamps the tray 200, the stepped surface of the first clamping block 612 also extends under the tray to support the tray 200. And the stepped surfaces of the two first clamping blocks 612 are opposite to each other and form a sliding track for the tray 200 to slide. The first clamping driving part 611 can drive the first clamping block 612 to expand and contract relative to the clamping station 104 to clamp and release the tray 200 from the left and right sides. The second clamping unit 62 includes a second clamping driving part 621 and a second clamping block 622. The second clamping driving part 621 can drive the second clamping block 622 to expand and contract relative to the clamping station 104. The third clamping unit 63 includes a third clamping driving part 631 and a third clamping block 632. The third clamping driving part 631 drives the third clamping block 632 to expand and contract relative to the clamping station 104. And the third clamping block 632 and the second clamping block 622 cooperate to clamp the tray 200 at the clamping station 104 from the front and rear sides.

[0049] Preferably, in order to facilitate the first clamping unit 61 to clamp the tray 200, the first clamping unit 61 further includes a clamping cylinder 614. The end of the clamping cylinder 614 forms a resisting block. The clamping cylinders 614 of the two first clamping units 61 are opposite in position. When clamping the tray 200, the clamping cylinders 614 of the two first clamping units 61 extend oppositely to clamp the tray 200. When moving the tray 200 from the clamping station 104 to the stacking station 105, the clamping cylinder 614 retracts to release the tray 200.

[0050] When the tray 200 is moved to the clamping station 104 by the lifting mechanism 30, the sensor at the clamping station 104 detects the tray. The first clamping drive part 611 drives the first clamping block 612 to clamp and support the tray 200 from both left and right sides of the clamping station 104. The second clamping drive part 621 drives the second clamping block 622 to limit the tray 200 from the front side of the clamping station 104. The third clamping drive part 631 drives the third clamping block to limit the tray 200 from the rear side of the clamping station 104 and cooperate with the second clamping block 612 to clamp the tray 200 from the front and rear sides. The tray 200 is fixed at the clamping station 104 for operation. After the electronic components on the tray 200 are picked up, the second clamping drive part 621 drives the second clamping block 622 to withdraw from the clamping station 104. The clamping cylinder 614 retracts to release the tray 200. The conveying device moves the released tray 200 from the clamping station 104 to the stacking station 105. The first clamping drive part 611 drives the first clamping block 612 to reset and withdraw from the clamping station 104. The third clamping drive part 631 drives the third clamping block 632 to withdraw from the clamping station 104.

[0051] Reference Figure 1 and Figure 10a The conveying device includes a transverse conveying mechanism 40. The transverse conveying mechanism 40 includes a transverse conveyor belt 42 installed on the rack, a transverse drive part 41 that drives the transverse conveyor belt 42 to rotate, a conveying bracket 43 installed on the transverse conveyor belt 42, and a pushing part 44 rotatably installed on the conveying bracket 43 and capable of pushing the tray 200 in the direction of the stacking station 105. The transverse drive part 41 drives the transverse conveyor belt 42 to act. The transverse conveyor belt 42 drives the pushing part 44 to move between the clamping station 104 and the stacking station 105 to push the tray 200 to the stacking station 105. Among them, the conveying bracket 43 is slidably connected to the sliding track 44 of the rack, and the transverse drive part 41 is installed on the rack. In this embodiment, the transverse drive part 41 drives the conveying bracket 43 to move through the transverse conveyor belt 42. In other embodiments, the conveying bracket 43 can be driven to move through other transmission mechanisms, which is not limited to the above embodiments.

[0052] Reference Figure 1 、 Figure 10b and Figure 10c The pushing part 44 includes a push block 442 located at one end of the rotating shaft 441 of the pushing part 44 and a counterweight block 443 located at the other end of the rotating shaft 441. The counterweight block 443 can drive the push block 442 to rise to the pushing position corresponding to the tray 200 at the clamping station 104 (such as Figure 1 Part A in Figure 10bAs shown, on the side of the conveying support 43 facing away from the stacking station 105, a limiting portion 431 adjacent to the pushing block 442 and a clearance groove 432 adjacent to the counterweight block 443 are formed. The limiting portion 431 restricts the rotational position of the pushing portion 44 to prevent the pushing portion 44 from rotating away from the stacking station 105 to a position below the pushing position. The clearance groove 432 provides a receiving space for the counterweight block 443 so that the pushing block 442 can rotate to a position below the pushing position under the action of a force towards the stacking station.

[0053] Reference Figure 1 , when the electronic devices on the tray 200 at the clamping station 104 are completely grabbed, the clamping device 60 releases the tray. At this time, the pushing portion 44 is located at the rear side of the clamping station 104 (the rear side of the tray 200). The lateral driving portion 41 drives the lateral conveyor belt 42 to move forward. The lateral conveyor belt 42 drives the pushing portion 44 to move towards the stacking station 105. The pushing block 442 pushes against the rear edge of the tray 200 from the rear side and pushes the tray 200 to the stacking station 105. At this time, the pushing block 442 is located at the rear edge of the stacking station 105 (as shown in Figure 1 Part B in and attached Figure 10c shown), the lateral driving portion 41 drives the lateral conveyor belt 42 to move in the reverse direction. The lateral conveyor belt 42 drives the pushing portion 44 to move towards the clamping station 104. Since a new tray 200 moves to the clamping station 104, the new tray pushes against the pushing block 442, causing the pushing block 442 to rotate downward to a position below the pushing position (as shown in Figure 1 Part A in and attached Figure 10b shown). The pushing portion 44 resets from below the tray 200 to the rear edge of the clamping station 104 and rotates upward to the pushing position under the action of the counterweight block 443.

[0054] On the side of the pushing portion 44 facing away from the stacking station 105, a first guiding surface is formed. The edge and the lower surface of the tray 200 can slide relative to the first guiding surface and drive the pushing block 442 of the pushing and positioning portion 44 to rotate downward.

[0055] Reference Figure 1 and Figure 11 , the stacking device 50 includes a stacking mounting frame 51 forming the stacking station 105, a stacking driving portion 52, a stacking support member (not shown in the figure), a plurality of support blocks 54 installed on the stacking mounting frame 51 and located at at least two opposite edges of the stacking station 105, and elastic members 55 installed between the support blocks 54 and the stacking mounting frame 51. The support blocks 54 can rotate relative to the stacking mounting frame 51 and can rotate downward to the lower limit position to extend into the stacking station 105 and support the tray 200 (as shown in Figure 1 and Figure 11As shown, it can be rotated upward to exit the stacking station 105 (not shown in the figure). The stacking support member (not shown in the figure) is located below the stacking station 105 and supports the tray 200 at the stacking station 105. The stacking support member is offset from the position of the support block 54. The stacking driving part 52 is connected to the stacking support member and drives the stacking support frame to lift and lower, so as to lift the tray 200 at the stacking station 105 above the support block 54. The elastic member 55 provides an elastic force for the support block 54 to rotate downward and extend into the stacking station 105.

[0056] Wherein, the upper surface of the support block 54 is the support surface 541, and the lower surface is the second guiding surface 542 for the tray 200 to slide. The tray 200 can slide relative to the guiding surface 542 and drive the support block 54 to rotate upward to disengage from the stacking station 105. The second guiding surface 542 extends gradually upward towards the stacking station 105 so that the support block 54 is wedge-shaped.

[0057] When the empty tray 200 is conveyed to the stacking station 105, a stack of trays is supported on the support block 54. The stacking support member (not shown in the figure) is located below the tray 200. The stacking driving part 52 drives the stacking support member to rise. The stacking support member pushes the tray 200 to move the tray 200 upward. When the tray 200 moves to the support block 54, it can push against the second guiding surface 542 of the support block 54 to drive the support block 54 to rotate upward to disengage from the stacking station 105. The stacking support member carries the stack of trays through the tray 200, and the tray 200 is stacked at the bottom of the stack of trays. The stacking support member drives the stack of trays to continue to rise until the bottom of the stack of trays reaches above the rotation path of the support block 54. The support block 54 rotates downward under the drive of the elastic member 55 and extends into the stacking station 105. The stacking driving part 52 drives the stacking support member to descend to the initial position. A new stack of trays is blocked by the support block 54 and supported on the support block 54, realizing the stacking work of the tray 200.

[0058] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
