Description

[0001] The utility model relates to the technical field of flexible circuit board processing equipment, and particularly relates to a conveying device. Background Art

[0002] With the continuous progress and development of society, various technical levels are constantly improving. Flexible circuit boards are favored for their excellent characteristics such as light weight, thin thickness, convenient installation, and free bending and folding.

[0003] After the flexible circuit boards are produced, their qualification rates need to be screened, and the screened products need to be sorted into corresponding packaging boxes. Currently, the existing equipment places two empty trays on it respectively to put qualified products and unqualified products into the corresponding trays respectively, and then the trays are manually carried to the designated position for packing. However, the working efficiency of this equipment is relatively low and the labor cost is high. Summary of the Utility Model

[0041] As Figure 1 shown, Figure 1 is a side view of the conveying device provided by an embodiment of the present utility model. In this embodiment, the conveying device includes: a frame 1, a first conveying mechanism 2, a second conveying mechanism 3, a lifting device 4, and a fourth conveying mechanism 5. The first conveying mechanism 2 is disposed at one end of the frame 1 and is used to convey a tray along the conveying direction (as shown by the x direction in Figure 1 ); the second conveying mechanism 3 is disposed at the other end of the frame 1 and is used to convey the tray in a direction opposite to the conveying direction; the lifting device 4 is disposed between the first conveying mechanism 2 and the second conveying mechanism 3. The lifting device 4 includes a lifting mechanism and a third conveying mechanism 3. The lifting mechanism is used to drive the third conveying mechanism 41 to switch between a first height and a second height. The third conveying mechanism 3 is used to receive the trays conveyed by the first conveying mechanism 2 and the second conveying mechanism 3 and convey the trays along the conveying direction; the fourth conveying mechanism 5 is disposed below the second conveying mechanism 3 and on the downstream side of the third conveying mechanism 41, and is used to receive the trays conveyed by the third conveying mechanism 4 and convey the trays along the conveying direction. Wherein, when the third conveying mechanism 41 is at the first height, both ends of the third conveying mechanism 41 are respectively docked with the output end of the first conveying mechanism 2 and the output end of the second conveying mechanism 3; when the third conveying mechanism 41 is at the second height, the output end of the third conveying mechanism 41 is docked with the input end of the fourth conveying mechanism 5.

[0042] In this embodiment, the first conveying mechanism 2 conveys the tray along the conveying direction to its output end. Qualified or unqualified flexible circuit boards are placed on the tray. The second conveying mechanism 3 conveys the tray along the direction opposite to the conveying direction to its output end, and unqualified or qualified flexible circuit boards are placed on the tray. After placement, the tray is conveyed onto the third conveying mechanism 41 of the lifting device 4, and the third conveying mechanism 41 is lowered from the first height to the second height by the lifting mechanism. The tray on the third conveying mechanism 41 is conveyed onto the fourth conveying mechanism 5, and the tray is conveyed out through the fourth conveying mechanism 5. Through the collaborative operation of each mechanism, the automatic transfer of the tray is realized, thereby reducing the labor intensity of workers and being beneficial to improving the operation efficiency of the equipment.

[0043] Further, as Figure 2 shown, Figure 2 is a partial three-dimensional structural diagram of the conveying equipment. In this embodiment, the frame 1 is of a frame structure, including a first cross frame 11 and a second cross frame 12 that extend horizontally and are arranged oppositely; there are two first conveying mechanisms 2, which are respectively arranged on the first cross frame 11 and the second cross frame 12 oppositely to each other. As Figure 3 shown, the first conveying mechanism 2 includes a first driving motor 21, a first conveyor belt 22, and a driving roller, a first guiding roller 24, a first driven roller 25, a second driven roller 26, and a second guiding roller 27 that the first conveyor belt 22 bypasses in sequence, wherein the driving end of the first driving motor 21 is connected to the driving roller.

[0044] Thus, by driving the driving roller to rotate by the first driving motor 21, the first conveyor belt 22 is driven to run along the conveying direction, so that when the tray is on the conveying surface of the first conveyor belt 22, the tray can be conveyed along the conveying direction.

[0045] Specifically, the two first conveying mechanisms 2 have the same structure and are symmetrically arranged on the first cross frame 11 and the second cross frame 12. The distance between them in the width direction (the direction perpendicular to the conveying direction, as shown by the y direction in Figure 2 ) is less than the length of the tray in the width direction, so that the tray can be placed on the first conveyor belt 22 of the first conveying mechanism 2. The first conveyor belt 22 of the first conveying mechanism 2 extends horizontally to the second driven roller 26 after passing through the first driven roller 25. The conveying surface between the first driven roller 25 and the second driven roller 26 is used to convey the tray. The upper sides of the first driven roller 25 and the second driven roller 26 are flush, so that the first conveyor belt 22 can convey the tray horizontally.

[0046] Further, as Figure 1 , Figure 6 and Figure 7 shown, above the input end of the first conveying mechanism 2 and above the input end of the second conveying mechanism 3, there are respectively provided a plurality of trays stacked and placed and a tray separating device 6.

[0047] The tray-splitting device 6 includes:

[0048] A tray-splitting mechanism 61 is disposed on the outer sides of the first cross-frame 11 and the second cross-frame 12. The tray-splitting mechanism 61 includes a tray-splitting drive motor 611 and a support plate 612. The drive end of the tray-splitting drive motor 611 is connected to the support plate 612 and is used to drive the support plate 612 to insert into and withdraw from between two adjacent trays at the bottommost layer;

[0049] A first lifting mechanism 62 is disposed between the first cross-frame 11 and the second cross-frame 12 and below a plurality of trays. The first lifting mechanism 62 is used to support the trays from the bottommost layer.

[0050] Adopting this technical solution, when the first lifting mechanism 62 ascends, it can support the entire stack of trays from the bottommost layer, and the tray-splitting mechanism 61 separates the trays at the bottommost layer. When the first lifting mechanism 62 descends, it can drive the trays at the bottommost layer to descend together and fall onto the first conveyor belt 22 of the first conveyor mechanism 2.

[0051] In this embodiment, a plurality of trays are respectively placed above the input end of the first conveyor mechanism 2 and above the input end of the second conveyor mechanism 3. The plurality of trays are stacked on top of each other from top to bottom. Four retaining bars 13 fixed to the frame 1 are respectively provided at the four corner portions of the placed trays to prevent the trays from shaking. Mounting elements 613 are respectively fixed to the outer sides of the first cross-frame 11 and the second cross-frame 12. The mounting element 613 includes a vertical portion and a horizontal portion. The vertical portion is fixed to the cross-frame by fasteners. A slide rail 614 extending in the width direction is provided on the upper surface of the horizontal portion. A slider 615 is provided on the lower surface of the support plate 612 for sliding connection with the slide rail 614. The drive end of the tray-splitting drive motor 611 is connected to the support plate 612 through a connecting member. Driven by the tray-splitting drive motor 611, the support plate 612 reciprocates in the width direction to insert the support plate 612 into and withdraw from between two adjacent trays. Optionally, in order to facilitate insertion between the trays, a downwardly inclined chamfer is provided at the front end of the support plate 612.

[0052] Furthermore, the first lifting mechanism 62 includes a first lifting motor 621, a first fixing plate 622, and a first movable plate 623 disposed above the first fixing plate 622. The first fixing plate 622 is fixed to the frame 1. The fixed end of the first lifting motor 621 is fixed to the first fixing plate 622. The drive end of the first lifting motor 621 is connected to the first movable plate 623 to drive the first movable plate 623 to reciprocate in the up and down direction.

[0053] Specifically, the first fixed plate 622 is horizontally fixed on the frame 1 and located below the first conveying mechanism 2. Both ends of the first fixed plate 621 are fixedly connected to the first cross frame 11 and the second cross frame 12 respectively. The fixed end of the first lifting motor 621 is fixed on the first fixed plate 622, and its driving end can pass through the first fixed plate 622 and extend upward or retract. The first movable plate 623 is arranged above the first fixed plate 622 in parallel with the first fixed plate 622. The driving end of the first lifting motor 621 is connected to the middle of the first movable plate 623. The first lifting motor 621 drives the first movable plate 623 to reciprocate in the up and down direction, so that when rising, it can lift the whole stack of trays from the bottom, and when descending, it can hold the bottom tray and place it on the first conveyor belt 22 of the first conveying mechanism 2.

[0054] Optionally, the first lifting motor 621 is a lead screw stepping motor, and the distance of the first movable plate 623 rising and falling is controlled by controlling the number of revolutions of the lead screw.

[0055] Optionally, a first in-place detection sensor is arranged on the first fixed plate 622 to detect whether the first movable plate 623 is in place when descending. More optionally, the first in-place detection sensor adopts a groove-type photoelectric switch sensor, the emitting end is arranged on the first fixed plate 622, and the receiving end is arranged on the first movable plate 623.

[0056] In this embodiment, a control unit is further included, and the control unit is electrically connected to the first in-place detection sensor. When the first in-place detection sensor detects the first movable plate 623, the first movable plate 623 has returned to the initial position. The initial position is the position where the first movable plate 623 is lower than the upper surface of the first conveyor belt 22.

[0057] Optionally, a first photoelectric detection sensor is arranged below the first movable plate 623 and is electrically connected to the control unit for detecting whether there is a tray on the first movable plate 623; a second photoelectric detection sensor is arranged inside the first cross frame 11 or the second cross frame 12 and is electrically connected to the control unit for detecting whether there is a tray on the first conveyor belt 22.

[0058] When neither the first photoelectric detection sensor nor the second photoelectric detection sensor detects a tray and the first in-place detection sensor detects the first movable plate 623, it means that the tray has been conveyed out and the next lifting operation can be performed. The control unit is also electrically connected to the first lifting motor 621, so as to control the first lifting motor 621 to operate to lift the first movable plate 623 to a predetermined position.

[0059] Optionally, first guide posts 624 are provided below the four corners of the first movable plate 623, and first guide sleeves 625 are provided at corresponding positions on the first fixed plate 622. Slide holes are provided on the first guide sleeves 625, and the first guide posts 624 pass through the slide holes and can move within the slide holes. Thus, not only can the first guide posts 624 be fixed, but also the movement of the first movable plate 623 can be limited.

[0060] Further, the width of the first movable plate 623 in the width direction of the frame 1 is smaller than the distance between the two first conveying mechanisms 2. Thus, the first movable plate 623 can pass through the space between the two first conveying mechanisms 2 to lift the tray and place the tray on the first conveying mechanism 2.

[0061] Further, as Figure 4 and Figure 5 shown, the lifting mechanism includes a second lifting motor 42 and a fixing frame 43. The third conveying mechanism 41 is arranged on the fixing frame 43, and the driving end of the second lifting motor 42 is connected to the fixing frame 43 so that the fixing frame 43 drives the third conveying mechanism 41 to switch between a first height and a second height.

[0062] Thus, the second lifting motor 42 drives the fixing frame 43 to move up and down, and further drives the third conveying mechanism 41 to reciprocate between the first height and the second height.

[0063] Further, as Figure 1 shown, in this embodiment, there are two sets of the third conveying mechanisms 41, and the two sets of the third conveying mechanisms 41 are arranged one above the other and operate in the same direction. When the third conveying mechanism 41 is at the first height, the upper third conveying mechanism 41 is docked with the first conveying mechanism 2 and the second conveying mechanism 3, and the lower third conveying mechanism 41 is docked with the fourth conveying mechanism 5.

[0064] Specifically, when the third conveying mechanism 41 is at the first height, the two ends of the upper third conveying mechanism 41 are respectively docked with the output ends of the first conveying mechanism 2 and the second conveying mechanism 3, and the trays conveyed by the first conveying mechanism 2 and the second conveying mechanism 3 can be output onto the upper third conveying mechanism 41. At this time, the output end of the lower third conveying mechanism 41 is docked with the input end of the fourth conveying mechanism 5, so that the trays conveyed on the lower third conveying mechanism 41 can be directly output onto the fourth conveying mechanism 5 through the lower third conveying mechanism 41 and the trays can be conveyed out. At this time, the lower layer conveys the trays without affecting the operation of the upper layer. As Figure 5 shown, when the third conveying mechanism 41 is at the second height, the second lifting motor 42 drives the fixing frame 43 to descend until the output end of the upper third conveying mechanism 41 is docked with the input end of the fourth conveying mechanism 5, so as to convey the trays on the upper third conveying mechanism 41 to the fourth conveying mechanism 5.

[0065] Further, as Figure 8 shown, it further includes a blocking device 8, which is arranged at the output end of the first conveying mechanism 2 and the output end of the second conveying mechanism 3. The blocking device 8 includes a third lifting motor 81 and a blocking plate 82 connected to the driving end of the third lifting motor 81, so as to drive the blocking plate 82 to reciprocate in the up and down direction.

[0066] Thus, when the tray is conveyed to the output end of the first conveying mechanism 2 or the output end of the second conveying mechanism 3, the third lifting motor 81 drives the blocking plate 82 to extend to limit the further movement of the tray. At this time, qualified or unqualified flexible circuit boards can be placed in the corresponding trays, and it will not affect the conveyance of the trays on the other side. For example, when the tray conveyed on the first conveying mechanism 2 reaches its output end, the blocking plate 82 extends, and the tray will no longer be conveyed forward. At this time, qualified flexible circuit boards are placed on the tray. After placing, the blocking plate 82 retracts, so as to continue to convey the tray with qualified flexible circuit boards to the upper third conveying mechanism 41 of the lifting device 4. And when the tray conveyed on the second conveying mechanism 3 reaches its output end, the blocking plate 82 extends. At this time, unqualified flexible circuit boards are placed on the tray. Similarly, after placing, the blocking plate 82 retracts, so as to continue to convey the tray with unqualified flexible circuit boards to the upper third conveying mechanism 41 of the lifting device 4.

[0067] Optionally, second in-place detection sensors are respectively arranged at the output end of the first conveying mechanism 2 and the output end of the second conveying mechanism 3 to detect whether the tray reaches the output end. In this embodiment, the second in-place detection sensor adopts a proximity switch and is electrically connected to the control unit. The control unit is also electrically connected to the third lifting motor 81 and the first driving motor 21. When the second in-place detection sensor detects the tray, the control unit controls the first driving motor 21 to stop running and controls the third lifting motor 81 to run to extend the blocking plate 82 so as to limit the further movement of the tray.

[0068] Further, as Figure 8 shown, the blocking device 8 further includes a second jacking mechanism 83. The second jacking mechanism 83 includes a fourth lifting motor 831, a second fixing plate 832, and a second movable plate 833 arranged above the second fixing plate 832. The second fixing plate 832 is fixed on the frame 1. The fixed end of the fourth lifting motor 831 is fixed on the second fixing plate 832, and the driving end of the fourth lifting motor 831 is connected to the second movable plate 833. The blocking plate 82 is arranged at the edge of the second movable plate 833 on the front side in the conveying direction.

[0069] Thus, the second movable plate 833 is lifted by the fourth lifting motor 831 so that the second movable plate 833 supports the tray, thereby being able to support the tray when the flexible circuit board is placed.

[0070] Specifically, the second fixed plate 832 is horizontally fixed on the frame 1, and both ends of the second fixed plate 832 are respectively fixed on the first cross frame 11 and the second cross frame 12. The fixed end of the fourth lifting motor 831 is fixed on the second fixed plate 832, and its driving end passes through the second fixed plate 832 and extends upward or retracts. The second movable plate 833 is arranged above the second fixed plate 832 in parallel with the second fixed plate 832, and the driving end of the fourth lifting motor 831 is connected to the middle of the second movable plate 833. The fourth lifting motor 831 drives the second movable plate 833 to reciprocate in the up and down directions, so that the tray can be supported when rising, and when descending, the tray is placed on the first conveyor belt 22 of the first conveyor mechanism 2.

[0071] Optionally, the fourth lifting motor 831 is a lead screw stepper motor, and the distance of the second movable plate 833 rising or descending is controlled by controlling the number of revolutions of the lead screw.

[0072] Optionally, in this embodiment, the control unit is also electrically connected to the fourth lifting motor 831. When the second in-place detection sensor detects the tray, the control unit also controls the fourth lifting motor 831 to operate to lift the second movable plate 833 to a predetermined position.

[0073] Optionally, second guide posts 834 are provided below the four corners of the second movable plate 833, second guide sleeves 835 are provided at corresponding positions of the second fixed plate 832, slide holes are provided on the second guide sleeves 835, and the second guide posts 834 pass through the slide holes and can move in the slide holes. Thus, not only can the second guide posts 834 be fixed, but also the movement of the second movable plate 833 can be limited.

[0074] Optionally, the width of the second movable plate 833 in the width direction is less than the distance between the two first conveyor mechanisms 2.

[0075] Furthermore, as Figure 4As shown, in this embodiment, the blocking device 8 is also disposed at both ends of the third conveyor mechanism 41 on the upper layer of the lifting device 4. Thus, when the tray is conveyed onto the third conveyor mechanism 41 on the upper layer of the lifting device 4, further movement of the tray can be restricted. Specifically, when the tray conveyed by the first conveyor mechanism 2 is conveyed onto the third conveyor mechanism 41 on the upper layer, the blocking device 8 at one end of the third conveyor mechanism 41 away from the first conveyor mechanism 2 operates to block the tray from moving towards the second conveyor mechanism 3; when the tray conveyed by the second conveyor mechanism 3 is conveyed onto the third conveyor mechanism 41 on the upper layer, the blocking device 8 at the other end of the third conveyor mechanism 41 away from the second conveyor mechanism 3 operates to block the tray from moving towards the first conveyor mechanism 2. Therefore, the tray can be limited in position on the lifting device 4, and then the tray can be driven to perform lifting operations.

[0076] Optionally, the distance between the blocking plates 82 of the two blocking devices 8 is the length of the tray. More optionally, when the tray is conveyed onto the third conveyor mechanism 41, the blocking plates 82 at both places can also be extended simultaneously to facilitate fixing the position of the tray.

[0077] Further, as Figure 2 shown, a fifth conveyor mechanism 7 is further included, which is disposed below the first conveyor mechanism 2 and is used to convey the tray along the conveying direction and dock with the third conveyor mechanism 41 of the lifting device 4.

[0078] When the third conveyor mechanism 41 is at the first height, the output end of the fifth conveyor mechanism 7 is docked with the input end of the third conveyor mechanism 41 on the lower layer. Thus, the tray can be directly conveyed out from the fifth conveyor mechanism 7, the third conveyor mechanism 41 on the lower layer, and the fourth conveyor mechanism 5, enabling the device to be compatible with multiple working modes, and the tray can be directly conveyed to the specified position by docking multiple conveying devices.

[0079] Further, in this embodiment, the structures of the first conveyor mechanism 2, the second conveyor mechanism 3, the third conveyor mechanism 41, the fourth conveyor mechanism 5, and the fifth conveyor mechanism 7 are the same. Thus, the structures of the second conveyor mechanism 3, the third conveyor mechanism 41, the fourth conveyor mechanism 5, and the fifth conveyor mechanism 7 will not be described in detail.

[0080] Working principle of the conveying device provided by the present utility model: When the first lifting motor 621 runs forward, it drives the first movable plate 623 to rise to a predetermined position, and jacks up a plurality of stacked trays from the bottom. The tray separation driving motor 611 drives the support plate 612 to insert forward between two adjacent trays at the bottom layer, so as to separate the bottom tray and hold the remaining upper trays. The bottom tray falls onto the first movable plate 623. The first lifting motor 621 runs in reverse to drive the first movable plate 623 to descend. When it descends to the initial position, the height of the first movable plate 623 is lower than the height of the first conveyor belt 22 of the first conveying mechanism 2, and the tray on the first movable plate 623 falls onto the first conveyor belt 22. The first driving motor 21 drives the first conveyor belt 22 to run to convey the tray along the conveying direction. When the tray reaches the output end of the first conveying mechanism 2 and the second in-place detection sensor detects the tray, the third lifting motor 81 drives the blocking plate 82 to rise to block the tray. At the same time, the first driving motor 21 stops running, and the fourth lifting motor 831 runs to lift the second movable plate 833 to a predetermined position to hold the tray, and the tray stops at the output end of the first conveying mechanism 2. At this time, a (for example, qualified) flexible circuit board can be placed. After placing the flexible circuit board, the third lifting motor 81 drives the blocking plate 82 to descend so that the tray can pass through; the fourth lifting motor 831 drives the second movable plate 833 to descend, and the tray falls onto the first conveyor belt 22. The first driving motor 21 runs, and at this time the upper third conveying mechanism 41 is at the first height, so that the first conveyor belt 22 can be driven to convey the tray onto the upper third conveying mechanism 41 of the lifting device 4. After the tray is conveyed onto the third conveying mechanism 41, the blocking devices 8 at both ends of the third conveying mechanism 41 run to raise the blocking plate 82 to fix the position of the tray. At the same time, the third conveying mechanism 41 stops running. The second lifting motor 42 runs to drive the fixing frame 43 to move downward to the second height, so that the output end of the upper third conveying mechanism 41 is docked with the input end of the fourth conveying mechanism 5. The blocking device 8 runs to lower the blocking plate 82 so that the tray can pass through, and the upper third conveying mechanism 41 runs to convey the tray onto the fourth conveying mechanism 5. The fourth conveying mechanism 5 runs to convey the tray out. The second conveying mechanism 3 conveys the tray from the other side of the frame 1 to the upper third conveying mechanism 41 of the lifting device 4, and conveys the tray onto the fourth conveying mechanism 5 when the third conveying mechanism 41 descends to the second height, and the fourth conveying mechanism 5 conveys the tray out. The working process of the second conveying mechanism 3 for conveying the tray is the same as that of the first conveying mechanism 2 for conveying the tray, except that the conveying direction is different, which will not be elaborated here.

[0081] The conveying device provided by the present utility model can realize automatic tray separation, flow, positioning, lifting and flowing away of trays, reduce the labor intensity of workers, and improve the operation efficiency of the device.

Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field within the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
