Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a conveying device and testing and sorting equipment for stacked trays. Background Technology

[0002] A material tray is a disc-shaped container used to hold materials. There are various types of material trays. In the material feeding process of some equipment, such as material sorting equipment and material testing equipment, materials are first loaded into material trays, and then multiple material trays are stacked together and placed on the equipment. Currently, the conveying devices for material trays on the equipment can only load each material tray sequentially. After all the material on the tray has been picked up, the existing equipment usually moves the empty tray using an additional handling device, which increases the structural complexity of the equipment and occupies a large space; or the trays are removed manually, which is labor-intensive. Therefore, the conveying devices for loading material trays on existing equipment do not have the function of unloading material trays, and their functions are limited. Utility Model Content

[0003] The main purpose of this utility model is to propose a conveying device and testing and sorting equipment for stacked trays, which aims to solve the technical problem of the single function of existing tray conveying devices.

[0008] In one embodiment, each of the support plates has a first groove on the side facing the placement cavity and corresponding to the material loading position, and each first groove communicates with the placement cavity. Each first groove is provided with a first receiving plate that can extend into the placement cavity. Each first receiving plate is used to extend into the placement cavity to receive the material tray located at the material loading position.

[0009] In one embodiment, the stacking mechanism includes two stacking assemblies, which are disposed on two support plates in a one-to-one correspondence. Each stacking assembly includes a second receiving plate and two third receiving plates. Each of the support plates has a second groove on the side facing the placement cavity and corresponding to the material unloading position, and each of the first grooves communicates with the placement cavity. Each of the second grooves is provided with a second receiving plate that can extend into the placement cavity. Each of the support plates also has two sliding grooves on the side facing the placement cavity, and the two sliding grooves are located on opposite sides of the second grooves. Each sliding groove extends vertically and communicates with the placement cavity. Each sliding groove is provided with a third receiving plate that can move vertically, and one end of the third receiving plate extends into the placement cavity. Each of the third receiving plates is used to drive the material tray supported on the first receiving plate to rise to the unloading position, and each of the second receiving plates is used to extend into the placement cavity to receive the material tray located at the unloading position.

[0010] In one embodiment, the top of the placement cavity is open, the top of each of the support plates protrudes upward to form a protrusion, two protrusions are arranged opposite each other, and a height limiting rod is connected between the two protrusions; the top of each of the support plates is recessed downward to form a relief groove, and two relief grooves are arranged opposite each other.

[0011] In one embodiment, the conveying mechanism includes: The conveyor has a loading end and a unloading end at opposite ends along the lateral direction. The top of the conveyor has an installation groove, and a conveyor belt is provided on the top of the installation groove. Both the installation groove and the conveyor belt extend from the loading end to the unloading end. The conveyor belt is used to receive the material tray pushed out from the opening and to drive the material tray to move between the loading end and the unloading end. A pushing mechanism is provided in the mounting groove near the feeding end. The pushing mechanism is used to push the material tray located at the feeding end from the opening to the feeding position.

[0012] In one embodiment, two conveyor belts are provided, and the two conveyor belts are arranged side by side and spaced apart; the pushing mechanism includes a pushing cylinder and a push plate, the pushing cylinder being used to drive the push plate to extend from the mounting groove between the two conveyor belts, so as to push the material tray located at the loading end from the opening to the loading position.

[0013] This utility model also proposes a testing and sorting device, comprising: Support platform; As described above, the conveying device for stacked trays is mounted on the support platform. A pick-and-place device is provided on the top of the support platform, and the unloading end of the conveying mechanism extends to the bottom of the pick-and-place device; A testing device is disposed on the top of the support platform and located on the side of the pick-and-place device away from the conveying device; The pick-and-place device is used to transfer the material in the tray at the feeding end to the testing device, and to test the material through the testing device; the pick-and-place device is also used to transfer the tested material on the testing device back to the tray at the feeding end.

[0014] This utility model discloses a stacked tray conveying device. The hopper forms a placement cavity with an opening on one side. The placement cavity has an upper and lower material position. The tray placed in the placement cavity is supported by a lifting mechanism, which can lift the tray to the upper material position. A push-out mechanism is provided so that when the tray is at the upper material position, it can be pushed out from the opening onto the conveying mechanism, which then moves the tray from the upper material position to the lower material position. When the tray is full of material at the lower material position or all the material in the tray is picked up, the conveying mechanism moves the tray from the lower material position to the upper material position and pushes it into the placement cavity from the opening, where it is positioned at the upper material position. Then, the stacked tray mechanism in the placement cavity receives the tray and lifts it from the upper material position to the lower material position. When multiple trays are stacked in the placement cavity, the lifting mechanism first raises the uppermost tray to the loading position and pushes it onto the conveying mechanism via the ejection mechanism. As this tray is pushed from the conveying mechanism into the placement cavity and raised from the loading position to the unloading position by the stacking mechanism, the lifting mechanism then raises another uppermost tray to the loading position. Understandably, when there is already a tray at the unloading position, the next tray to arrive at the unloading position will be stacked on top of the previous tray, causing the previous tray to rise and fall, thus achieving tray unloading and stacking. Therefore, the stacking tray conveying device of this invention can not only be used to load trays but also to unload trays after the material in the tray has been completely picked up or filled. It can also stack multiple trays for unloading, combining both loading and unloading stacking, offering more functionality. Attached Figure Description

[0022] This utility model proposes a conveying device 100 for a stacked tray 200.

[0023] It should be noted that the tray 200 is used to place materials, and in this embodiment, the materials placed in the tray 200 are illustrated using radio frequency devices as an example.

[0024] Please see Figures 1 to 4 In one embodiment of this utility model, the conveying device 100 includes a hopper 1, a lifting mechanism 2, a pushing mechanism 3, a conveying mechanism 5, and a stacking mechanism 4. The hopper 1 forms a placement cavity 11 for placing a material tray 200. An opening 12 communicating with the placement cavity 11 is provided on one side of the hopper 1. The placement cavity 11 is provided with an upper material position and a lower material position. The upper material position is provided corresponding to the opening 12, and the lower material position is provided above the upper material position. The lifting mechanism 2 is provided in the placement cavity 11 and located below the upper material position. The material tray 200 placed in the placement cavity 11 is supported on the lifting mechanism 2, and the lifting mechanism 2 is used to drive the material tray 200 on it to rise to the upper material position. The pushing mechanism 3 is provided on the side of the hopper 1 away from the opening 12. The pushing mechanism 3 is used to push the material tray 200 located in the upper material position to the upper material position. The material tray 200 is pushed out from the opening 12; the conveying mechanism 5 is set on one side of the silo 1 where the opening 12 is opened, and the top of the conveying mechanism 5 is set corresponding to the opening 12. The two ends of the conveying mechanism 5 along its extension direction are the loading end 511 and the unloading end 512, respectively. The loading end 511 is set near the silo 1 to receive the material tray 200 pushed out from the opening 12. The conveying mechanism 5 is used to drive the material tray 200 to move between the loading end 511 and the unloading end 512, and to push the material tray 200 located at the loading end 511 from the opening 12 to the loading position; the stacking mechanism 4 is set in the placement cavity 11. The stacking mechanism 4 is used to receive the material tray 200 located at the loading position, and is also used to drive the material tray 200 at the loading position to rise to the unloading position.

[0025] The conveying device 100 of the stacked tray 200 of this utility model has a hopper 1 forming a placement cavity 11, with an opening 12 on one side of the placement cavity 11. The placement cavity 11 is provided with an upper material position and an lower material position. The tray 200 placed in the placement cavity 11 is supported on a lifting mechanism 2. The lifting mechanism 2 can drive the tray 200 to the upper material position. By providing a pushing mechanism 3, when the tray 200 is at the upper material position, the pushing mechanism 3 can push the tray 200 from the opening 12 to the conveying mechanism 5. The conveying mechanism 5 drives the material tray 200 from the loading end 511 to the unloading end 512. When the material tray 200 is full of material at the unloading end 512 or when all the material in the material tray 200 is picked up, the conveying mechanism 5 also drives the material tray 200 from the unloading end 512 to the loading end 511, and pushes the material tray 200 from the opening 12 into the placement cavity 11 and positions it at the loading position. Then, the stacking mechanism 4 set in the placement cavity 11 receives the material tray 200 and drives the material tray 200 from the loading position to the unloading position. When multiple trays 200 are stacked in the placement cavity 11, the lifting mechanism 2 first lifts the uppermost tray 200 to the upper position and pushes it onto the conveying mechanism 5 through the pushing mechanism 3. When the tray 200 is pushed from the conveying mechanism 5 into the placement cavity 11 and lifted from the upper position to the lower position by the stacking mechanism 4, the lifting mechanism 2 then lifts another uppermost tray 200 to the upper position. Understandably, when there is already a tray 200 at the unloading position, the next tray 200 arriving at the unloading position will be stacked on the bottom of the previous tray 200, and will drive the previous tray 200 to rise and fall, thereby realizing the unloading and stacking of the trays 200. Therefore, the conveying device 100 of the stacked tray 200 of this utility model can not only be used to realize the loading of the tray 200, but also to realize the unloading of the tray 200 after the material in the tray 200 has been completely picked up or filled with material, and can stack multiple trays 200 for unloading, taking into account both the loading and unloading stacking of the trays 200, thus having more functions.

[0026] Please see Figure 1 and Figure 2 In one embodiment, the hopper 1 includes a baffle 14 and two support plates 13. The two support plates 13 are spaced apart and form a placement cavity 11 and an opening 12. The ends of the two support plates 13 away from the opening 12 also form an inlet 15 communicating with the placement cavity 11. One end of the baffle 14 is hinged to one end of one of the support plates 13 facing the inlet 15. The baffle 14 can rotate around the support plate 13 to which it is hinged to open or close the inlet 15.

[0027] Understandably, the hopper 1 includes a baffle 14 and two support plates 13. The two support plates 13 form an opening 12 and an inlet 15. The baffle 14 is hinged to one of the support plates 13, so that the baffle 14 can rotate to open or close the inlet 15. When the inlet 15 is opened, it is convenient to place the material tray 200 into the placement cavity 11. When the baffle 14 closes the inlet 15, it ensures that the environment inside the placement cavity 11 is not affected by the outside world and prevents dust from entering the placement cavity 11.

[0028] In one embodiment, the lifting mechanism 2 includes two lifting components 21, which are respectively disposed on the side of the two support plates 13 facing the placement cavity 11. Each lifting component 21 includes a support block 211 and a lifting drive component 212. The material tray 200 placed in the placement cavity 11 is supported on the two support blocks 211. The two lifting drive components 212 are respectively used to drive the two support blocks 211 to lift and lower, so as to drive the material tray 200 to lift and lower.

[0029] Understandably, by setting two lifting components 21, each located on a separate support plate 13, and each lifting component 21 including a support block 211 and a lifting drive component 212, the stability of the material tray 200 is effectively ensured by supporting its front and rear sides on the two support blocks 211, thus preventing the tray 200 from tilting. Furthermore, the two support blocks 211 drive the tray 200 to rise and fall, making the lifting process smoother and more stable.

[0030] It should be noted that in this embodiment, the lifting drive component 212 is a drive motor, and a synchronous belt is connected to the drive motor. The synchronous belt is arranged vertically, and the support block is connected to the corresponding synchronous belt. When the drive motor rotates, it drives the support block to rise and fall through the synchronous belt.

[0031] Please see Figure 2 and Figure 3 In one embodiment, the ejection mechanism 3 includes a support base 31, an ejection cylinder 32, and a push rod 33. The support base 31 is located above the baffle 14, and both ends of the support base 31 are respectively connected to two support plates 13. The ejection cylinder 32 is disposed on the top of the support base 31 and located between the two support plates 13. The push rod 33 is connected to the ejection cylinder 32. The ejection cylinder 32 is used to drive the push rod 33 to extend or retract from the placement cavity 11, so as to eject the material tray 200 located at the upper material position from the opening 12 through the push rod 33.

[0032] Understandably, the two ends of the support base 31 are connected to the two support plates 13 respectively. The push cylinder 32 is set on the support base 31. When the material tray 200 of the upper position needs to be pushed out of the opening 12 by the push rod 33, the cylinder is pushed up to run, which drives the push rod 33 to extend into the placement cavity 11 to abut and push the material tray 200 toward the opening 12 until the material tray 200 is fully received on the conveying mechanism 5.

[0033] Please continue reading. Figure 3 In one embodiment, each support plate 13 is provided with a first groove 131 on the side facing the placement cavity 11 and corresponding to the material loading position, and each first groove 131 is connected to the placement cavity 11. Each first groove 131 is provided with a first receiving plate 16 that can extend into the placement cavity 11. Each first receiving plate 16 is used to extend into the placement cavity 11 to receive the material tray 200 located at the material loading position.

[0034] In this embodiment, each support plate 13 has a first groove 131 on the side facing the placement cavity 11, and the first groove 131 corresponds to the position of the loading position. When the lifting mechanism 2 drives the material tray 200 to rise to the loading position, the first receiving plate 16 in each first groove 131 extends out, thereby receiving the material tray 200 located at the loading position through the two first receiving plates 16. It can be understood that when multiple material trays 200 are stacked in the placement cavity 11, the lifting mechanism 2 drives the uppermost material tray 200 to rise to the loading position. By extending the first receiving plate 16 from the groove to receive the uppermost material tray 200, the lifting mechanism 2 can then drive the remaining material trays 200 to descend, thereby ensuring that when the ejection mechanism 3 ejects the material tray 200 at the loading position, it is not disturbed by the other material trays 200, and the ejection is smoother. Furthermore, each of the first receiving plates 16 extends laterally and has a guiding function, ensuring that the material tray 200 moves laterally when it is pushed out, making it smoother and preventing the material tray 200 from shaking, making it more stable and reliable.

[0035] Please continue reading. Figure 3 In one embodiment, the stacking mechanism 4 includes two stacking assemblies, which are correspondingly disposed on two support plates 13. Each stacking assembly includes a second receiving plate 41 and two third receiving plates 42. Each support plate 13 has a second groove 132 on the side facing the placement cavity 11 and corresponding to the unloading position. Each first groove 131 communicates with the placement cavity 11, and each second groove 132 is provided with a second receiving plate 41 that can extend into the placement cavity 11. Each support plate 13 also has a second receiving plate 41 on the side facing the placement cavity 11. Two slids 133 are provided, and the two slids 133 are located on opposite sides of the second groove 132. Each slid 133 extends vertically and communicates with the placement cavity 11. Each slid 133 is provided with a third receiving plate 42 that can move vertically, and one end of the third receiving plate 42 extends into the placement cavity 11. Each third receiving plate 42 is used to drive the material tray 200 supported on the first receiving plate 16 to rise to the unloading position. Each second receiving plate 41 is used to extend into the placement cavity 11 to support the material tray 200 located at the unloading position.

[0036] In this embodiment, the stacking mechanism 4 includes two stacking assemblies, which are correspondingly disposed on two support plates 13. Each stacking assembly includes a second receiving plate 41 and two third receiving plates 42. A second groove 132 is formed on the support plate 13 at the position corresponding to the unloading position, and a second receiving plate 41 is disposed in the second groove 132. In addition, a sliding groove 133 is formed on the support plate 13 on opposite sides of the second groove 132, and a third receiving plate is disposed in the sliding groove 133. 42; During unloading, the conveying mechanism 5 pushes the tray 200 back from the opening 12 to the loading position, where it is received by the first receiving plate 16. After the first receiving plate 16 receives the tray 200, the third receiving plates 42 in each chute 133 rise and fall, thereby receiving the tray 200 and driving it to rise. When the tray 200 rises to the unloading position, the second receiving plate 41 in the second groove 132 extends out of the groove, thereby receiving the tray 200 and placing it in the unloading position. Afterwards, since the loading position is vacant, the lifting mechanism 2 can continue to drive the tray 200 on it to rise to the loading position, and then continue to push the tray 200 out through the ejection mechanism 3.

[0037] Understandably, when a tray 200 is already on the second receiving plate 41 at the unloading position, the third receiving plate 42 can continue to drive the tray 200 upwards. When the second receiving plate 41 retracts into the second groove 132, the tray 200 on it overlaps with the tray 200 on the third receiving plate 42. Therefore, the hopper 1 in this embodiment can realize the automatic stacking and automatic ejection of the trays 200 onto the conveying mechanism 5 without manual intervention, and it is powerful and more versatile.

[0038] Furthermore, each chute 133 is provided with two vertically spaced third receiving plates 42, and the two third receiving plates 42 can slide vertically within the chute 133 simultaneously. The lower third receiving plate 42 is used to lift the tray 200 located at the upper material position, and the upper third receiving plate 42 is used to lift the tray 200 located at the lower material position. When the tray 200 is moved to the lower material position by the lower third receiving plate 42, the second receiving plate 41 extends from the second groove 132 to catch the tray 200. Then, the upper third receiving plate 42 lifts the tray 200 on it to descend until it is stacked with the tray 200 at the lower material position. By setting two third receiving plates 42, the stacking of the trays 200 is more stable, the collision force during stacking of the trays 200 is reduced, and the trays 200 are effectively protected.

[0039] It should be noted that both the first receiving plate 16 and the second receiving plate 41 can be driven by a cylinder, so that the first receiving plate 16 extends into and out of the first groove 131, and the second receiving plate 41 extends into and out of the second groove 132.

[0040] Please see Figure 2 In one embodiment, the top of the placement cavity 11 is open, and the top of each support plate 13 protrudes upward to form a protrusion 17. The two protrusions 17 are arranged opposite each other, and a height limiting rod 18 is connected between the two protrusions 17. The top of each support plate 13 is recessed downward to form a relief groove 19, and the two relief grooves 19 are arranged opposite each other.

[0041] Understandably, by making the top of the placement cavity 11 open, it is easier to remove and transfer multiple stacked trays 200. The recessed support plate 13 forms a clearance groove 19, which makes it easier to move the stacked trays 200 out. Furthermore, by setting a height limit bar 18, it is further prevented from the trays 200 from being stacked too high and shaking, thus improving reliability.

[0042] Please see Figure 1 and Figure 4 In one embodiment, the conveying mechanism 5 includes a conveying platform 51 and a pushing mechanism 52. The two opposite ends of the conveying platform 51 in the transverse direction are a loading end 511 and a unloading end 512, respectively. The top of the conveying platform 51 is provided with a mounting groove 513, and the top of the mounting groove 513 is provided with a conveyor belt 514. Both the mounting groove 513 and the conveyor belt 514 extend from the loading end 511 to the unloading end 512. The conveyor belt 514 is used to receive the tray 200 pushed out from the opening 12 and to drive the tray 200 to move between the loading end 511 and the unloading end 512. The pushing mechanism 52 is disposed in the mounting groove 513 near the loading end 511. The pushing mechanism 52 is used to push the tray 200 located at the loading end 511 from the opening 12 to the loading position.

[0043] Understandably, in this embodiment, by providing an installation groove 513 on the conveyor table 51 and a conveyor belt 514 on top of the installation groove 513, when the material tray 200 in the hopper 1 is pushed out from the opening 12, the material tray 200 is supported on the conveyor belt 514, and the conveyor belt 514 drives the material tray 200 to move between the loading end 511 and the unloading end 512. Furthermore, by providing a pushing mechanism 52 within the installation groove 513 and near the loading end 511, when the material tray 200 moves from the unloading end 512 to the loading end 511, the pushing mechanism 52 pushes the material tray 200 back to the corresponding loading position in the hopper 1. The automated process of transferring the material tray 200 from the conveying device 100 to the hopper 1 requires no manual intervention and is highly efficient.

[0044] In one embodiment, two conveyor belts 514 are provided, arranged side by side and spaced apart. The pushing mechanism 52 includes a pushing cylinder 521 and a pusher plate 522. The pushing cylinder 521 drives the pusher plate 522 to extend from the mounting groove 513 between the two conveyor belts 514 to push the material tray 200 located at the loading end 511 from the opening 12 to the loading position. Understandably, the spaced arrangement of the two conveyor belts 514 not only keeps the material tray 200 stable but also mainly avoids the pusher plate 522. The pushing cylinder 521 drives the pusher plate 522 to extend from between the two conveyor belts 514, thereby pushing the material tray 200 from the opening 12 into the placement cavity 11.

[0045] This utility model also proposes a testing and sorting device, including a support platform, a pick-and-place device, a testing device, and a conveying device 100 of a stacked tray 200 as described above. The conveying device 100 is disposed on the support platform; the pick-and-place device is disposed on the top of the support platform, and the unloading end 512 of the conveying mechanism 5 extends to the bottom of the pick-and-place device; the testing device is disposed on the top of the support platform and located on the side of the pick-and-place device away from the conveying device 100; the pick-and-place device is used to transfer the material located in the tray 200 at the unloading end 512 to the testing device, and to test the material through the testing device; the pick-and-place device is also used to transfer the tested material on the testing device to the tray 200 located at the unloading end 512.

[0046] Understandably, when used only for material testing (such as RF devices), multiple conveying devices 100 can be configured, where at least one tray 200 in the hopper 1 is a loading tray 200 used to place the RF device to be tested, and at least two trays 200 in the hopper 1 are unloading trays 200 used to place the RF device after testing. Before testing, the RF device to be tested needs to be placed in the loading tray 200, while the unloading tray 200 is empty. At the start of testing, each hopper 1 fills its tray with the contents of the loading tray. The material tray 200 is transferred to the corresponding conveying device 100. That is, both the loading tray 200 and the unloading tray 200 are transferred to the corresponding conveying device 100 and conveyed to the pick-and-place station by the conveying device 100. During testing, the pick-and-place device only picks up the RF device to be tested in the loading tray 200. After testing, according to the test results of the RF device, the RF device is placed in different unloading trays 200. For example, one unloading tray 200 is used to place qualified RF devices, and one unloading tray 200 is used to place unqualified RF devices.

[0047] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made under the technical concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
