[0049] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0052] References to "one embodiment", "some embodiments" or "an embodiment" described in the specification of this application mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some other embodiments", "in some other embodiments", etc., which appear at different places in this specification, do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. In addition, in one or more embodiments, particular features, structures or characteristics may be combined in any suitable manner.

[0053] In order to illustrate the technical solution of the present application, a description is given below with reference to specific drawings and embodiments.

[0054] In the related technology, the entire operation process of the loading equipment is long, and the user needs to build a complete information system with a complex structure. The research and development cost is high, and it is not convenient to obtain the size information of the circuit board. If the system fails or the network fails, etc., it will lead to the inability to obtain the size information of the circuit board, which is inconvenient for maintenance and affects the production line.

[0055] In view of this, the present application provides a conveying device and a feeding device, which can improve the problems of the existing circuit board feeding equipment having a complex structure, being inconvenient to obtain the size information of the circuit board, and being inconvenient to maintain.

[0056] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the structure of a feeding device 100 in one embodiment of the present application. Figure 2 yes Figure 1 The partial enlarged view of the A part of the feeding device 100 is shown. Figure 3 yes Figure 1 A top view of the loading device 100 is shown.

[0057] In a first aspect, an embodiment of the present application provides a conveying device for a loading device 100 , wherein the conveying device includes a frame 10 , a conveying mechanism 20 , a clapper mechanism 30 and an ultrasonic sensor 40 .

[0058] The conveying mechanism 20 is rotatably disposed on the frame 10 , and is used to convey the circuit board 200 .

[0059] The conveying mechanism 20 may include a conveying belt or a conveying roller 21, etc. The conveying direction of the conveying mechanism 20 may be along the direction indicated by the arrow K in the figure.

[0060] The clapping mechanism 30 is disposed above the conveying mechanism 20 , and is used to push the circuit board 200 so that the length direction of the circuit board 200 or the width direction of the circuit board 200 is parallel to the conveying direction of the conveying mechanism 20 .

[0061] The ultrasonic sensor 40 is disposed at one side of the conveying mechanism 20 . The ultrasonic sensor 40 is used to send ultrasonic signals to the circuit board 200 and to receive ultrasonic signals reflected by the circuit board 200 .

[0062] The ultrasonic sensor 40 can be arranged on the upper side, lower side, left side or right side of the conveying mechanism 20. When the circuit board 200 on the conveying mechanism 20 passes the ultrasonic sensor 40, the ultrasonic sensor 40 can send ultrasonic signals to the circuit board 200 and can receive ultrasonic signals reflected by the circuit board 200, and the ultrasonic sensor 40 can obtain sensing signals, and at this time, timing can be started by a timer or timing software. When the circuit board 200 on the conveying mechanism 20 leaves the ultrasonic sensor 40, the ultrasonic sensor 40 cannot send ultrasonic signals to the circuit board 200 and cannot receive ultrasonic signals reflected by the circuit board 200, and the ultrasonic sensor 40 cannot obtain sensing signals, and at this time, timing can be stopped by a timer or timing software, and the time between starting timing and stopping timing is the sensing time of the ultrasonic sensor 40.

[0063] As can be seen from the above, the conveying device provided in the embodiment of the present application, since the clapper mechanism 30 is arranged above the conveying mechanism 20, the clapper mechanism 30 can push the circuit board 200 so that the length direction of the circuit board 200 or the width direction of the circuit board 200 is parallel to the conveying direction of the conveying mechanism 20. Since the ultrasonic sensor 40 is arranged on one side of the conveying mechanism 20, the ultrasonic sensor 40 can send an ultrasonic signal to the circuit board 200 and receive the ultrasonic signal reflected by the circuit board 200, so that the timing can be started when the circuit board 200 on the conveying mechanism 20 passes the ultrasonic sensor 40, and the timing can be stopped when the circuit board 200 on the conveying mechanism 20 leaves the ultrasonic sensor 40, and the sensing time is obtained. Multiplying it by the conveying speed of the conveying mechanism 20, the length dimension information or width dimension information of the circuit board 200 can be obtained. The structure is simple, the operation is convenient, it is convenient to obtain the dimension information of the circuit board 200, and it is convenient to maintain.

[0064] The conveying mechanism 20 has an input end 201 and an output end 202 , the ultrasonic sensor 40 is disposed at the output end 202 , and the circuit board 200 can be conveyed from the input end 201 to the output end 202 .

[0065] Such a configuration can avoid abnormal sensing of the ultrasonic sensor 40 due to sensing the structure of the conveying mechanism 20 itself (such as the roller 21, etc.) or other structures.

[0066] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the conveying mechanism 20 includes a first power member and a plurality of rollers 21. The first power member is in transmission connection with the rollers 21. The rollers 21 are rotatably disposed on the frame 10. The plurality of rollers 21 are spaced apart along the conveying direction of the conveying mechanism 20. The rollers 21 are used to support the circuit board 200.

[0067] By adopting the above solution, the structure of the conveying mechanism 20 can be made simpler and easier to process, and abnormal sensing of the ultrasonic sensor 40 due to sensing of the roller 21 of the conveying mechanism 20 can be avoided.

[0068] Optionally, the ultrasonic sensor 40 is disposed on the side of the roller 21 away from the circuit board 200, and the ultrasonic sensor 40 is disposed between two adjacent rollers 21. In this configuration, the ultrasonic sensor 40 can send ultrasonic signals to the circuit board 200 through the gap between the two adjacent rollers 21 and receive ultrasonic signals reflected by the circuit board 200.

[0069] It is understandable that when the ultrasonic sensor 40 is disposed between two adjacent rollers 21 , the distance between the two adjacent rollers 21 should be large enough to avoid affecting the sensing signal of the ultrasonic sensor 40 .

[0070] The ultrasonic sensor 40 is disposed at the lower side of the roller 21, and the ultrasonic sensor 40 sends ultrasonic signals from bottom to top to the circuit board 200. This arrangement can avoid the problem that the ultrasonic sensor 40 sends ultrasonic signals from top to bottom to the circuit board 200, causing the ultrasonic sensor 40 to sense the roller 21 and receive the ultrasonic signal reflected by the roller 21, which makes the ultrasonic sensor 40 prone to false sensing.

[0071] Specifically, the first power member may include a motor and a transmission gear, etc.

[0072] Please continue to refer to Figure 1 , Figure 2 and Figure 3 In the present embodiment, two clapping mechanisms 30 are provided and the two clapping mechanisms 30 are respectively located on both sides of the conveying mechanism 20; the clapping mechanism 30 includes a second power member and a clapping member 31 connected to each other, and the second power member is used to drive the clapping member 31 to move in a direction perpendicular to the conveying direction of the conveying mechanism 20, so that the clapping member 31 pushes the circuit board 200.

[0073] By adopting the above solution, the structure of the clapping mechanism 30 can be made simpler and it is convenient to push the circuit board 200 so that the length direction of the circuit board 200 or the width direction of the circuit board 200 is parallel to the conveying direction of the conveying mechanism 20.

[0074] Specifically, the second power component may include a cylinder, a hydraulic cylinder, a screw motor or a linear module, etc.

[0075] Optionally, a clapper sensor may be provided, and the clapper sensor is used to detect whether the circuit board 200 reaches the clapper position. The clapper sensor may be a position sensor or the like.

[0076] Please refer to Figure 1 , Figure 2 and Figure 3 In a second aspect, an embodiment of the present application provides a loading device 100, and the loading device 100 includes a conveying device as in the first aspect.

[0077] In the feeding device 100 provided in the embodiment of the present application, since the clapper mechanism 30 of the conveying device is arranged above the conveying mechanism 20, the clapper mechanism 30 can be used to push the circuit board 200 so that the length direction of the circuit board 200 or the width direction of the circuit board 200 is parallel to the conveying direction of the conveying mechanism 20. In addition, since the ultrasonic sensor 40 is arranged on one side of the conveying mechanism 20, the ultrasonic sensor 40 can be used to send an ultrasonic signal to the circuit board 200 and receive the ultrasonic signal reflected by the circuit board 200, so that the timing can be started when the circuit board 200 on the conveying mechanism 20 passes the ultrasonic sensor 40, and the timing can be stopped when the circuit board 200 on the conveying mechanism 20 leaves the ultrasonic sensor 40, and the sensing time is obtained. Then, multiplied by the conveying speed of the conveying mechanism 20, the length dimension information or width dimension information of the circuit board 200 can be obtained. The structure is simple, the operation is convenient, the dimension information of the circuit board 200 can be obtained, and the maintenance is convenient.

[0078] The feeding device 100 provided in the embodiment of the present application uses an ultrasonic sensor 40, which has stronger compatibility with the circuit board 200, strong resistance to environmental interference, is not affected by the color or transparency of the circuit board 200, has a lower false alarm rate, high stability, and can also work in a dark environment. The overall solution of the feeding device 100 provided in the embodiment of the present application is low in cost, low in technical difficulty, and easy to promote and use.

[0079] In this embodiment, the feeding device 100 further includes a control system, and the conveying mechanism 20 and the ultrasonic sensor 40 are both electrically connected to the control system.

[0080] By adopting the above scheme, the conveying speed of the conveying mechanism 20 can be automatically adjusted using the control system according to the length dimension information or width dimension information of the circuit board 200 obtained by the ultrasonic sensor 40, without the need for manual setting, thereby avoiding failure to adjust the conveying speed of the conveying mechanism 20 due to manual negligence at work.

[0081] Specifically, the control system may include a PLC (Programmable Logic Controller) or a single chip microcomputer, etc. In this embodiment, the control system includes a PLC.

[0082] Please refer to Figure 4 , Figure 5 and Figure 6 , Figure 4 yes Figure 3 The partial enlarged view of the B portion of the feeding device 100 shown, Figure 5 yes Figure 1 The front view of the feeding device 100 shown, Figure 6 It is a logical relationship diagram between the width (board width) of the circuit board 200 and the opening degree of the proportional valve in one of the embodiments of the present application.

[0083] The loading device 100 further includes a board placing mechanism, which is used to place the circuit board 200 on the conveying mechanism 20 , and the board placing mechanism is electrically connected to the control system.

[0084] By adopting the above scheme, the control system can be used to automatically adjust the conveying speed of the conveying mechanism 20 according to the length dimension information or width dimension information of the circuit board 200 obtained by the ultrasonic sensor 40, and the control system can be used to automatically adjust the speed of placing the circuit board 200 on the conveying mechanism 20, thereby ensuring that the distance between two adjacent circuit boards 200 on the conveying mechanism 20 is optimal, ensuring that the horizontal line equipment connected behind the loading equipment 100 can produce more circuit boards 200 in the shortest time, and the equipment utilization rate is greatly improved.

[0085] It should be noted that the control system may include a timing unit, which can obtain the sensing time of the ultrasonic sensor 40. The control system obtains the sensing time of the ultrasonic sensor 40, and then multiplies it by the conveying speed of the conveying mechanism 20 to obtain the length or width of the circuit board 200. Finally, the board placement speed is automatically adjusted through the algorithm pre-imported by itself (the length or width of the circuit board 200 corresponds to the board placement speed) to ensure the optimal board placement spacing and increase the equipment utilization rate.

[0086] Optionally, the plate placing mechanism may include a robot or a plate placing machine, etc.

[0087] In this embodiment, the board placement mechanism includes a flip assembly 60, which includes a third power member and a flip member 61 connected to each other. The flip member 61 is used to hook the circuit board 200 (such as Figure 5 The third power member is used to drive the flap member 61 to rotate so that the circuit board 200 is flipped to be parallel to the conveying direction of the conveying mechanism 20, and the third power member is electrically connected to the control system.

[0088] By adopting the above solution, the circuit board 200 placed at an angle to the conveying direction of the conveying mechanism 20 can be flipped to be parallel to the conveying direction of the conveying mechanism 20 , so that the conveying mechanism 20 can convey the circuit board 200 .

[0089] Specifically, the flap member 61 is provided with a clamping hook for hooking the circuit board 200 .

[0090] Optionally, the third power member may include a cylinder, a hydraulic cylinder or a motor, etc. The circuit board 200 placed at an angle to the conveying direction of the conveying mechanism 20 may be placed on the L-shaped carrier.

[0091] Specifically, the third power member includes a flap cylinder and a proportional valve connected to the flap cylinder, and the proportional valve is electrically connected to the control system. In this way, the flap speed of the flap assembly 60 can be automatically adjusted using the control system according to the length dimension information or width dimension information of the circuit board 200 obtained by the ultrasonic sensor 40, thereby adjusting the speed of placing the circuit board 200 on the conveying mechanism 20.

[0092] In this embodiment, the board placing mechanism also includes a suction plate assembly 70, which includes a suction plate power member 71 and a vacuum suction cup 72 connected to each other. The vacuum suction cup 72 is used to adsorb the circuit board 200 placed at an angle to the conveying direction of the conveying mechanism 20. The suction plate power member 71 is used to drive the vacuum suction cup 72 to move toward the direction close to the flip plate member 61 so that the flip plate member 61 hooks the bottom of the circuit board 200. The suction plate power member 71 is electrically connected to the control system.

[0093] With such arrangement, the suction plate power member 71 can be used to drive the vacuum suction cup 72 to move toward the direction close to the flip member 61, so that the flip member 61 hooks the bottom of the circuit board 200, thereby facilitating the rotation of the flip member 61 to flip the circuit board 200 to be parallel to the conveying direction of the conveying mechanism 20.

[0094] Optionally, the suction plate power member 71 may include a cylinder, a hydraulic cylinder or a motor.

[0095] In this embodiment, the feeding device 100 further includes a paging assembly 80 and a feeding conveyor belt 90. The paging assembly 80 includes a paging cylinder 81, which is used to abut the circuit board 200 when the third power member drives the flap member 61 to rotate, so that the circuit board 200 is flipped to be parallel to the conveying direction of the conveying mechanism 20, and the speed at which the paging cylinder 81 abuts the circuit board 200 is the paging speed. The feeding conveyor belt 90 is used to convey the L-shaped carrier, and the L-shaped carrier placed on the trolley can be conveyed by the feeding conveyor belt 90 to a position where the vacuum suction cup 72 can adsorb the circuit board 200 placed at an angle to the conveying direction of the conveying mechanism 20.

[0096] Please refer to Figures 1 to 5When the feeding device 100 provided in the above embodiment is used, the user places the L-shaped carrier on the trolley at the end of the previous production process, stacks the circuit board 200 on the L-shaped carrier, and then transports the trolley to the front of the feeding device 100 and locks the trolley. The subsequent process is as follows:

[0097] First, each time the board placement signal is triggered, the loading conveyor belt 90 drives the L-shaped carrier to move forward until the photoelectric sensor on the side of the loading conveyor belt 90 senses the circuit board 200, and the L-shaped carrier reaches the board placement preparation position. The vacuum suction cup 72 can absorb the circuit board 200 placed at an angle to the conveying direction of the conveying mechanism 20.

[0098] Secondly, the plate suction power part 71 pushes forward, the vacuum suction cup 72 fits with the bottom of the circuit board 200, and the solenoid valve is turned on to generate negative pressure and suction. The vacuum suction cup 72 sucks the bottom of the circuit board 200, and the plate suction power part 71 retreats, pulling the bottom of the first circuit board 200 onto the clamping hook of the flip part 61. At the same time, the feeding conveyor belt 90 reverses, driving the L-shaped carrier to move backward to the board placement preparation position, separating the bottom of the first circuit board 200 from the bottom of the second circuit board 200.

[0099] Once again, when the L-shaped carrier returns to the board placement preparation position (also the flip board safety position), the third power member starts to operate, and at the same time, there is a paging cylinder 81 at the bottom of the third power member. At this time, the paging cylinder 81 pushes up from the gap between the bottom of the first circuit board 200 and the bottom of the second circuit board 200, and flips the circuit board 200 from the inclined vertical state at an angle to the conveying direction of the conveying mechanism 20 to the pre-placement safety position. If there is a circuit board 200 on the conveying mechanism 20 at this moment, it will wait for this circuit board 200 to be conveyed forward for a certain distance, and the flip board assembly 60 will flip the circuit board 200 to a horizontal state parallel to the conveying direction of the conveying mechanism 20; if there is no board on the conveying mechanism 20 at this moment, the flip board assembly 60 will directly flip the circuit board 200 to a horizontal state, and place the circuit board 200 on the roller 21 on the conveying horizontal plane.

[0100] Then, the first power part of the conveying mechanism 20 starts to operate, driving the circuit board 200 to be transported forward to a certain distance. The clapping sensor senses the presence of the circuit board 200, the first power part stops operating, and the clapping mechanism 30 operates to make the length direction of the circuit board 200 or the width direction of the circuit board 200 parallel to the conveying direction of the conveying mechanism 20.

[0101] Then, after the board is finished, the first power member operates again to transport the circuit board 200 to the rear horizontal line equipment. During this period, the flap assembly 60 flips back to the original position.

[0102] Finally, the roller 21 of the conveying mechanism 20 drives the circuit board 200 to be transported forward. When the circuit board 200 passes over the ultrasonic sensor 40, the ultrasonic sensor 40 receives a signal and the PLC starts to count continuously. When the circuit board 200 leaves the ultrasonic sensor 40, the PLC stops counting. After the PLC obtains the sensing time of the ultrasonic sensor 40, it multiplies it by the conveying speed of the conveying mechanism 20 to obtain the length dimension information or width dimension information of the circuit board 200.

[0103] Please refer to the general Figure 6 , a logical relationship diagram between the width of the circuit board 200 (board width) and the opening degree of the proportional valve is drawn up.

[0104] The overall speed of the loading device 100 is affected by the flipping speed, paging speed, board clapping speed and conveying speed, while the paging speed, board clapping speed and conveying speed are not affected by the size of the circuit board 200. Under the condition of not affecting the equipment performance and the quality of the circuit board 200, the faster the speed, the better, which is a fixed value.

[0105] The flipping speed will be affected by the size of the circuit board 200, because the larger the circuit board 200 is, the smaller the grip of the vacuum suction cup 72 on the circuit board 200 is. If the flipping speed is very fast, the board will easily fall off. At the same time, as the size of the circuit board 200 is larger, the waiting time from the pre-placement safety position to the horizontal conveying position is longer. If the speed of the flipping assembly 60 is adjusted according to the size of the circuit board 200, the entire flipping action can be stabilized, and the waiting time for the pre-placement safety position can be reduced without affecting the overall board placement time. When the size of the circuit board 200 is smaller, if the flipping speed when the circuit board 200 is wider is still used, the overall board placement time will be lengthened, and the spacing between the circuit boards 200 will be larger, affecting the equipment utilization rate.

[0106] Therefore, the plate releasing speed mentioned in the embodiment of the present application is actually the flipping speed of the flap assembly 60, and the flipping speed of the flap assembly 60 is controlled by the air flow passing through the flap cylinder. The larger the air flow, the faster the flipping speed. A proportional valve for controlling the gas flow is installed in front of the flap cylinder. The air flow can be controlled by adjusting the numerical value of the proportional valve, thereby controlling the flipping speed.

[0107] Depend on Figure 6It can be seen that when we get the width of the circuit board 200, we can calculate what value the board placement speed should be set to so that the spacing between the boards can reach the optimal value we expect. According to this logical relationship diagram, after the PLC indirectly calculates the board width through the sensing time of the ultrasonic sensor 40, it will automatically calculate the optimal board turning speed and automatically adjust the opening of the proportional valve to ensure that when producing circuit boards 200 of this board width, the spacing between the boards is optimal. The loading equipment 100 will measure the board width data of each circuit board 200 in real time. When the PLC detects that the board width of the circuit board 200 has changed through the ultrasonic sensor 40, it can automatically adjust the board turning speed to always ensure that the spacing between the boards is optimal without manual intervention. When the spacing between the boards is optimal, it means that the horizontal line equipment connected behind the board placement equipment can produce more circuit boards 200 in the shortest time, and its equipment utilization rate is greatly improved.
