The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments, in case at least two embodiments are combined together without contradiction.

Referring to fig. 1 to fig. 3, the present application provides a feeding device 1, where the feeding device 1 is used to operate a workpiece 2 to be processed, and the workpiece 2 may be, but is not limited to, a circuit board, and the like, that is, the feeding device 1 provided in the present application may be, but is not limited to, applied in the field of circuit board processing, and is not limited herein.

The feeding device 1 comprises a driving device 10, a carrying device 20 and a clamping device 30, and the structure, the operation principle, the interaction relationship and the like of each device are described in detail below with reference to the accompanying drawings.

The driving device 10 may be motor-driven, hydraulic-driven, pneumatic-driven, etc.

The carrier 20 is connected to the driving device 10 to be moved by the driving device 10. The carrying device 20 includes a bracket 210 and at least one set of carrying racks 220 carried on the bracket 210. The driving device 10 may be directly connected to the bracket 210 or directly connected to the loading stage 220. The number of the loading platforms 220 may be 1 group, or may be multiple groups (e.g., 2 groups, 3 groups, 5 groups, 7 groups, etc.). In the drawings related to the present application, only the number of the loading stages 220 is 6, and the arrangement direction is the X-axis direction for exemplary explanation.

Further, each set of the loading rack 220 includes a plurality of loading boards 221, and the specific number may be, but is not limited to, 2, 3, 5, 6, 9, and the like. Each carrier plate 221 is used for carrying the member to be processed 2. If the number of the loading racks 220 is N, each group includes M loading boards 221, the loading device 20 can load at most N × M workpieces 2 to be processed.

Further, the plurality of carrier plates 221 are spaced along a predetermined direction (Z-axis direction in fig. 1, which may also be referred to as a height direction), and can move back and forth in the predetermined direction under the driving of the driving device 10. In other words, the moving direction of the carrier 20 is the same as the arrangement direction (the preset direction) of the plurality of carrier plates 221.

The holding device 30 is used for holding the workpiece 2 to be processed and transporting the workpiece 2 to be processed on the plurality of bearing plates 221 from the first end a1 of the bearing device 20 to the second end a2 of the bearing device 20 layer by layer. In fig. 3, the relative direction of the first end a1 and the second end a2 is the Y-axis direction. The number of the holding devices 30 is determined by the number of the sets of the carrying racks 220, i.e., the number of the holding devices 30 is equal to the number of the sets of the carrying racks 220. When the number is greater than or equal to 2, the holding devices 30 correspond to the carrying stages 220 one by one, and different holding devices 30 correspond to different carrying stages 220.

Further, the height of the clamping device 30 is fixed, and each of the carrying plates 221 on the carrying device 20 is provided with the workpiece 2 to be processed, and since the carrying device 20 can move in the preset direction, the clamping device 30 can clamp and convey the workpiece 2 to be processed to the second end a2 at the first end a1 layer by layer. For example, firstly, the driving device 10 maintains the carrier plate 221 on the carrier device 20 at a target height, then the clamping device 30 clamps the workpiece 2 to be processed on the carrier plate 221 and transports the workpiece 2 to the second end a2 from the first end a1, after the transport is completed, the clamping device 30 withdraws from the motion path of the carrier device 20 to avoid obstructing the motion of the carrier device 20, then the driving device 10 drives the carrier device 20 to ascend in a preset direction so that the carrier plate 221 reaches the target height, and maintains the carrier plate 221 at the target height, then the clamping device 30 clamps the workpiece 2 to be processed on the carrier plate 221 and transports, and withdraws from the motion path of the carrier device 20 after the transport is completed, then the driving device 10 drives the carrier device 20 to ascend again until the clamping device 30 transports the workpiece 2 to be processed on the M-th carrier plate 221 (last) from the first end a1 to the second end a2, thereby realizing the process that the clamping device 30 transports the workpieces 2 to be processed on the plurality of bearing plates 221 layer by layer.

In summary, the feeding device 1 provided by the present application includes a driving device 10, a carrying device 20, and a clamping device 30, wherein the driving device 10 is configured to drive the carrying device 20 to move, each carrying plate 221 in the carrying device 20 can carry the workpiece 2 to be processed, and the clamping device 30 is configured to transport the workpiece 2 to be processed on each carrying plate 221 layer by layer from the first end a1 to the second end a2 of the carrying device 20, so as to implement the operation of the workpiece 2 to be processed to different stations to complete each process. It can be understood that the feeding device 1 provided by the application can realize the transportation of a plurality of workpieces to be processed 2, thereby meeting the requirement of mass production and further improving the production efficiency.

As can be seen from the above description, the clamping device 30 can clamp and transport the workpiece 2 to be processed on the carrying plate 221 layer by layer, in the process, the clamping device 30 at least generates a clamping action and a transporting action, and both actions require power consumption for driving. In some special cases, there may be no workpiece 2 to be processed on one or more of the carrier plates 221, which may result in waste of power if the clamping device 30 still performs the above two actions, especially in mass production, and therefore, it is necessary to provide a device capable of detecting whether there is a workpiece 2 to be processed on the carrier plates 221. The arrangement and the detection principle of the detection device for detecting the member to be processed 2 will be described in detail below.

Referring to fig. 4 and 5, in an embodiment, the feeding device 1 further includes a first detecting device 40, the first detecting device 40 includes a first sensor 410, a second sensor 420 and a processor 440, and the processor 440 is electrically connected to the first sensor 410 and the second sensor 420.

The first sensor 410 is located on one side of the carrier 20, and is spaced apart from the carrier 20 and is fixedly disposed, where the fixed disposition means that the first sensor 410 does not move along with the carrier 20. Further, the first sensors 410 are disposed opposite to the carrying stage 220, and the number of the first sensors 410 is determined by the number of the sets of the carrying stage 220, i.e., the number of the first sensors 410 is equal to the number of the sets of the carrying stage 220. When the number is greater than or equal to 2, the first sensors 410 are opposite to the carriage 220 one by one, and different first sensors 410 are opposite to different carriages 220. Each first sensor 410 is used for detecting whether the workpiece 2 to be processed exists on each loading board 221 on the loading rack 220 corresponding to the first sensor. The first sensor 410 may be, but is not limited to, an infrared sensor.

The second sensor 420 is disposed at one side of the carrying device 20 along the predetermined direction and is fixedly disposed, where the fixed disposition means that the second sensor 420 is at least partially fixed to another stationary component of the non-carrying device. The second sensor 420 is a distance detection sensor for acquiring the position information of the carrying device 20 in real time. It is understood that the number of the second sensors 420 is 1 to achieve the above-described functions. The second sensor 420 may be, but not limited to, a pull cord encoder, where the pull cord encoder includes a pull cord 421 and a functional body 422 (as shown in fig. 5), the functional body 422 is fixedly disposed and does not move along with the supporting device 20, one end of the pull cord 421 is connected to the functional body 422, the other end of the pull cord 421 is connected to the supporting device 20, the pull cord 421 is extended during the movement of the supporting device 20 in a preset direction, and the functional body 422 can acquire the real-time position of the supporting device 20. In other embodiments, the second sensor 420 may be an ultrasonic sensor, an infrared sensor, or the like spaced apart from the carrier 20 to measure a distance.

The specific detection principle is as follows: the second sensor 420 is used for acquiring the position information of the carrying device 20 and sending a first position signal to the processor 440. The processor 440 is configured to generate a first control signal upon receiving the first position signal. The first control signal is used for controlling the first sensor 410 to detect whether the workpiece 2 to be machined exists on the bearing plate 221.

It can be understood that, since the plurality of carrier plates 221 in each set of carrier tables are spaced apart, the workpieces 2 to be processed carried on different carrier plates 221 are also spaced apart, and only when the workpieces 2 to be processed move to the position corresponding to the first sensor 410, the first sensor 410 can detect whether the workpieces 2 to be processed exist on the carrier plates 221 at present. Therefore, the second sensor 420 is used for obtaining the position data of the carrying device 20 in the moving process in real time and sending the position data to the processor 440, and the processor 440 is used for judging whether the current position of the carrying device 20 meets the condition that the workpiece 2 to be processed is opposite to the first sensor 410 in real time, and if so, controlling the first sensor 410 to start detection.

It can be understood that, in the setting form of the embodiment, firstly, the electric quantity can be saved, the first sensor 410 does not need to be started all the time, and secondly, the bearing load on which the workpiece to be processed 2 exists can be accurately recorded, and the bearing load on which the workpiece to be processed 2 does not exist can be accurately recorded, so that whether the clamping device 30 is controlled to move or not to prepare for the subsequent operation or not can be conveniently performed.

Referring to fig. 6 to 8, in another embodiment, the feeding device 1 further includes a first detecting device 40, the first detecting device 40 includes a first sensor 410, a third sensor 430 and a processor 440, and the processor 440 is electrically connected to the first sensor 410 and the third sensor 430.

The first sensor 410 is located on one side of the carrier 20, and is spaced apart from the carrier 20 and is fixedly disposed, where the fixed disposition means that the first sensor 410 does not move along with the carrier 20. Further, the first sensors 410 are disposed opposite to the carrying stage 220, and the number of the first sensors 410 is determined by the number of the sets of the carrying stage 220, i.e., the number of the first sensors 410 is equal to the number of the sets of the carrying stage 220. When the number is greater than or equal to 2, the first sensors 410 are opposite to the carriage 220 one by one, and different first sensors 410 are opposite to different carriages 220. Each first sensor 410 is used for detecting whether the workpiece 2 to be processed exists on each loading board 221 on the loading rack 220 corresponding to the first sensor. The first sensor 410 may be, but is not limited to, an infrared sensor.

The third sensor 430 is located at one side of the carrying device 20, and is spaced apart from the carrying device 20 and is fixedly disposed, where the fixed disposition means that the third sensor 430 does not move along with the carrying device 20. A plurality of positioning marks 230 (in the area of the dashed box in fig. 7) are disposed on the carrying device 20 along the preset direction. The positioning mark 230 may be, but is not limited to, a hole, a groove, a protrusion, etc. The third sensor 430 is used for acquiring the position information of the carrying device 20 through the plurality of positioning identifiers 230. It is understood that the number of the third sensors 430 is 1 to achieve the above-described functions. The third sensor 430 may be, but is not limited to, an infrared sensor, an ultrasonic sensor, etc.

The distance between the adjacent carrier boards 221 in the same set of carrier racks 220 is defined as a first distance. The spacing distance between adjacent positioning markers 230 is defined as a second distance. The first distance and the second distance are equal. Since the positioning mark 230 is disposed on the carrying device 20, the positioning mark 230 moves by the same distance as the carrying device 20 moves, and therefore the current position of the carrying device 20 can be obtained by detecting the position of the mark.

Optionally, the number of the positioning marks 230 is the same as the number of the loading boards 221 on the same group of loading racks 220, the positioning marks 230 are disposed opposite to the loading boards 221, and different positioning marks 230 are disposed opposite to different loading boards 221.

The specific detection principle is as follows: the third sensor 430 is configured to acquire the position information of the carrying device 20 through the plurality of positioning identifiers 230 and send a first position signal to the processor 440. The processor 440 is configured to generate a first control signal upon receiving the first position signal. The first control signal is used for controlling the first sensor 410 to detect whether the workpiece 2 to be machined exists on the bearing plate 221.

As described in the above embodiments, since the plurality of carrier plates 221 in each set of carrier tables are spaced apart, the workpieces 2 to be processed carried on different carrier plates 221 are also spaced apart, and only when the workpieces 2 to be processed move to the position opposite to the first sensor 410, the first sensor 410 can detect whether the workpieces 2 to be processed exist on the carrier plates 221. Therefore, the third sensor 430 is used for acquiring position data of the carrying device 20 in the moving process in real time and sending the position data to the processor 440, and the processor 440 is used for judging whether the current position of the carrying device 20 meets the condition that the workpiece 2 to be processed is opposite to the first sensor 410 in real time, and if so, controlling the first sensor 410 to start detection.

It can be understood that, in the setting form of the embodiment, firstly, the electric quantity can be saved, the first sensor 410 does not need to be started all the time, and secondly, the bearing load on which the workpiece to be processed 2 exists can be accurately recorded, and the bearing load on which the workpiece to be processed 2 does not exist can be accurately recorded, so that whether the clamping device 30 is controlled to move or not to prepare for the subsequent operation or not can be conveniently performed.

It should be noted that in the above two detection embodiments, the first sensor 410 and the processor 440 have the same function, and the second sensor 420 and the third sensor 430 also have the same function for detecting the position information of the carrying device 20, except that the arrangement positions of the second sensor 420 and the third sensor 430 are different, so the detection principles of the second sensor 420 and the third sensor 430 are also different.

Referring to fig. 9, in combination with any one of the above detection embodiments, the first sensor 410 of the first detection device 40 is configured to send a confirmation signal to the processor 440 after detecting that the workpiece 2 to be processed exists on the carrier plate 221. The processor 440 is further configured to generate a second control signal after receiving the acknowledgement signal. The second control signal is used for controlling the clamping device 30 to clamp the workpiece 2 to be processed and to transport the workpiece from the first end a1 of the carrying device 20 to the second end a2 of the carrying device 20. If the first sensor 410 detects that there is no workpiece 2 to be processed on the carrier plate 221, the processor 440 does not need to control the clamping device 30 to perform the clamping action and the moving action, and it can be understood that this configuration is advantageous to save power, especially in mass production.

It should be noted that the detection process of the workpiece 2 to be processed and the circulation process of the workpiece 2 to be processed may be performed separately or alternately. The separation is performed by using the first detection device 40 to detect the carrying device 20 layer by layer, and after the whole carrying device 20 is detected, the holding device 30 is used to operate the workpieces 2 to be processed on the carrying device 20 layer by layer. The cross-proceeding means that the first detection device 40 is used for detecting the first layer of the bearing device 20, after the first layer is detected, the clamping device 30 is used for operating the workpiece 2 to be processed on the first layer, after the first layer is operated, the first detection device 40 is used for detecting the second layer, the clamping device 30 operates the second layer, and the process is repeated until the last layer is finished.

Optionally, referring to fig. 10, the bearing plate 221 includes a first bearing plate 2211 and a second bearing plate 2212. The first loading plate 2211 and the second loading plate 2212 are spaced apart from each other to form a spaced space B1. The clamping device 30 is at least partially accommodated in the space B1. It will be appreciated that the movement of the holding device 30 holding the workpiece 2 needs to be ensured that the movement of the holding device 30 cannot deviate from the target path, which may result in the workpiece 2 not being accurately transferred to the target station. In this embodiment, the clamping device 30 is at least partially received in the space B1 formed by the first loading plate 2211 and the second loading plate 2212, so that the movement of the clamping device 30 can be limited by the first loading plate 2211 and the second loading plate 2212, and the purpose of preventing the clamping device 30 from deviating from the target path is achieved, thereby ensuring that the workpiece 2 to be processed is accurately transferred to the target station.

As can be seen from the foregoing description, in the process of moving the workpiece 2 to the target station from the feeding device 1, the accuracy of the position of the workpiece 2 needs to be ensured, so as to ensure that the workpiece 2 can smoothly move to the target station and ensure the subsequent processing precision. Referring to fig. 3, the feeding device 1 provided by the present application further includes a second detecting device 50, where the second detecting device 50 is used for positioning the workpiece 2 before the workpiece is operated to the target station. The structure, position and positioning principle of the second detecting device 50 will be described in detail with reference to the accompanying drawings.

The second detecting device 50 is located at the second end a2 of the carrying device 20, and is spaced apart from the carrying device 20 and is fixedly disposed, so that the second detecting device 50 does not move along with the carrying device 20. Further, the second detecting devices 50 are disposed opposite to the carrying racks 220, and the number of the second detecting devices 50 is determined by the number of the sets of the carrying racks 220, i.e. the number of the second detecting devices 50 is equal to the number of the sets of the carrying racks 220. When the number is greater than or equal to 2, the second detection devices 50 are opposed to the carrying stages 220 one by one, and different second detection devices 50 are opposed to different carrying stages 220. Each second inspection device 50 is used to realize the positioning of the workpiece 2 to be processed on the corresponding carrying rack 220.

Referring to fig. 11 to 13, the second detecting device 50 includes a fourth sensor 510 and a positioning plate 520. The positioning plate 520 is fixedly disposed beside the supporting device 20 and is adjacent to the second end a2 of the supporting device 20. The fourth sensor 510 is carried on the positioning board 520.

The workpiece 2 to be machined comprises a main body 22 and a positioning part 21, wherein the positioning part 21 is convexly arranged on the main body 22. The fourth sensor 510 is configured to send a second position signal to the processor 440 when the positioning member 21 on the workpiece 2 passes through the positioning plate 520. The processor 440 is further configured to control the holding device 30 to stop moving after receiving the second position signal. When the clamping device 30 stops moving, the position of the workpiece 2 to be processed is a positioning position, and the workpiece 2 to be processed is located at the position, so that the workpiece 2 to be processed can be ensured to smoothly run to a target station, and the subsequent processing precision can be ensured.

Referring to fig. 11 to 13, the positioning plate 520 includes a first plate 521 and a second plate 522. The first plate 521 and the second plate 522 are spaced apart to form a passage space B2. The passage space B2 is used to accommodate the positioning member 21 on the member to be machined 2. The first plate 521 is opposite to the first loading plate 2211. The second plate 522 is used to be opposite to the second loading plate 2212. The passage space B2 is used to be opposite to the above-mentioned space B1.

Specifically, the workpiece 2 to be processed held by the holding device 30 is moved from the first end a1 to the second end a2 of the carrying device 20, and the positioning member 21 on the workpiece 2 is located in the space B1. Subsequently, the workpiece 2 to be machined enters the region of the second inspection device 50 from the second end a2, and the positioning element 21 on the workpiece 2 to be machined enters the passage space B2 from the separation space B1. It can be understood that, during the movement of the workpiece 2 to be processed, it is necessary to ensure that the movement of the workpiece 2 to be processed cannot deviate from the target path, otherwise the workpiece 2 to be processed cannot be accurately transferred to the target station. In the present embodiment, the positioning member 21 of the workpiece 2 to be processed can enter the passage space B2 formed by the first plate 521 and the second plate 522, so that the movement of the workpiece 2 to be processed can be limited by the first plate 521 and the second plate 522, and the purpose of preventing the workpiece 2 to be processed from deviating from the target path can be achieved, and the workpiece 2 to be processed can be accurately transferred to the target station.

Referring to fig. 12, the second detecting device 50 further includes a movable element 540. The movable member 540 is movably connected to the first plate 521 and at least partially located in the passage space B2. The movable member 540 is used for moving after being touched by the positioning member 21 on the workpiece 2 to be processed. The fourth sensor 510 faces a side of the movable member 540. The fourth sensor 510 is configured to generate the second position signal upon detecting movement of the moveable member 540. In other words, due to the limited size of the passage space B2, the positioning member 21 of the workpiece 2 certainly touches the movable member 540 during the movement of the member in the passage space B2. The movable member 540 is movably connected to the first plate 521, so that the movable member 540 moves relative to the first plate 521 after being touched by the positioning member 21. The fourth sensor 510 is configured to sense whether the moving member 540 moves, and if so, send a second position signal to the processor 440, and after the processor 440 receives the second position signal, control the clamping device 30 to stop moving, so as to position the workpiece 2 at the current position, thereby ensuring that the workpiece 2 can smoothly run to the target station, and ensuring subsequent processing accuracy. The fourth sensor 510 may be, but is not limited to, a proximity switch, an infrared sensor, an ultrasonic sensor, and the like.

Referring to fig. 12, the movable member 540 is rotatably connected to the first plate 521. The second detecting device 50 further includes an elastic member 530. The elastic member 530 may be, but is not limited to, a spring, etc. The elastic member 530 has one end fixed to the first plate 521 and the other end connected to the movable member 540. The elastic member 530 is used for providing a restoring elastic force to the movable member 540 after the movable member 540 is touched by the positioning member 21 on the member to be processed 2 to rotate. Specifically, when the movable element 540 does not rotate, the elastic element 530 is in a natural state, and after the movable element 540 is collided by the positioning element 21 and is driven, the elastic element 530 is compressed or elongated by the movable element 540, so that the movable element 540 receives an elastic force that the elastic element 530 intends to return to the natural state, and after the positioning element 21 leaves the movable element 540, the movable element 540 returns to a non-rotating position under the elastic force, so that the return is realized.

Referring to fig. 12, optionally, the second detecting device 50 further includes a first traveling wheel 523 and a second traveling wheel 524. The first roller 523 is rotatably connected to one end of the first plate 521 near the carrier 20, and the second roller 524 is rotatably connected to one end of the second plate 522 near the carrier 20. The first and second running wheels 523 and 524 are spaced apart from each other and form an entrance B21 of a passage space B2. It can be understood that when the positioning member 21 on the member 2 to be processed passes through the entrance B21 during the process of entering the passage space B2, if the positioning member 21 contacts the first traveling wheel 523 or the second traveling wheel 524 during the process of advancing, the first traveling wheel 523 or the second traveling wheel 524 will rotate without causing an obstruction to the movement of the positioning member 21. Therefore, the first and second running wheels 523 and 524 function here to guide the positioning member 21 smoothly into the passage space B2.

Referring to fig. 12, optionally, the second detecting device 50 further includes a third traveling wheel 525 and a fourth traveling wheel 526. The third roller 525 is rotatably connected to an end of the first plate 521 away from the carrier 20, and the fourth roller 526 is rotatably connected to an end of the second plate 522 away from the carrier 20. The third and fourth running wheels 525 and 526 are spaced apart from each other and form an outlet B22 of the passage space B2. It will be appreciated that when the positioning member 21 of the member 2 to be processed passes through the exit opening B22 during exiting the passage space B2, if the positioning member 21 contacts the third traveling wheel 525 or the fourth traveling wheel 526 during advancing, the third traveling wheel 525 or the fourth traveling wheel 526 will rotate without causing an obstruction to the movement of the positioning member 21. Therefore, the third and fourth running wheels 525 and 526 function here to guide the positioning member 21 smoothly out of the passage space B2.

Referring to fig. 12 and 14, the positioning plate 520 has a notch B3 at a position adjacent to the movable member 540, and the notch B3 is communicated with the passage space B2. The second detecting device 50 further includes a limiting member 550, and the limiting member 550 is inserted into the gap B3 and the channel space B2. The stopper 550 is used to block the passage space B2 to block the movement of the positioning member 21 on the member to be processed 2, so as to ensure that the member to be processed 2 stops moving in time after being detected by the fourth sensor 510. As can be seen from the foregoing description, the processor 440 controls the holding device 30 to stop moving after the fourth sensor 510 detects the workpiece 2 to be processed, but in practical situations, there is a certain inertia in both the workpiece 2 and the holding device 30, and there is a certain delay in the control effect, so that the workpiece 2 does not stop in time. The limiting member 550 of the present embodiment can solve the problem that the workpiece 2 cannot be stopped in time, so as to ensure the accuracy of the subsequent operation.

Although embodiments of the present application have been shown and described, it is understood that the above embodiments are illustrative and not restrictive, and that those skilled in the art may make changes, modifications, substitutions and alterations to the above embodiments without departing from the scope of the present application, and that such changes and modifications are also to be considered as within the scope of the present application.
