DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0036] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments when at least two embodiments are combined together without contradiction.

[0037] Please refer to Figures 1 to 3 The present application provides a feeding device 1, which is used to move a workpiece 2 to be processed. The workpiece 2 to be processed can be but is not limited to a circuit board, etc., that is, the feeding device 1 provided in the present application can be but is not limited to the field of circuit board processing, and is not limited here.

[0038] The feeding device 1 includes a driving device 10, a carrying device 20 and a clamping device 30. The structure, operation principle, interaction relationship, etc. of each device are described in detail below with reference to the accompanying drawings.

[0039] The driving device 10 can be driven by a motor, a hydraulic pressure, or a pneumatic pressure.

[0040] The carrying device 20 is connected to the driving device 10 to achieve movement through the driving device 10. The carrying device 20 includes a bracket 210 and at least one group of carrying platforms 220 carried by the bracket 210. The driving device 10 can be directly connected to the bracket 210, or directly connected to the carrying platform 220. The number of the carrying platforms 220 can be 1 group, or multiple groups (such as 2 groups, 3 groups, 5 groups, 7 groups, etc.). In the relevant drawings of the present application, only 6 groups of the carrying platforms 220 are used as an example, and the arrangement direction is the X-axis direction.

[0041] Further, each group of the carrying platforms 220 includes a plurality of carrying plates 221, the specific number of which may be, but is not limited to, 2, 3, 5, 6, 9, etc. Each carrying plate 221 is used to carry the workpiece 2 to be processed. If the number of the carrying platforms 220 is N groups, and each group includes M carrying plates 221, the carrying device 20 can carry a maximum of N×M workpieces 2 to be processed.

[0042] Furthermore, the plurality of supporting plates 221 are arranged along a preset direction ( Figure 1 The carrier device 20 is arranged at intervals in the Z-axis direction (also referred to as the height direction) and can move back and forth in the preset direction under the drive of the driving device 10. In other words, the movement direction of the carrier device 20 is the same as the arrangement direction (preset direction) of the plurality of carrier plates 221.

[0043] The clamping device 30 is used to clamp the workpiece 2 to be processed, and transport the workpiece 2 to be processed on the plurality of carrier plates 221 layer by layer from the first end A1 of the carrier device 20 to the second end A2 of the carrier device 20. Figure 3 , the relative direction of the first end A1 and the second end A2 is the Y-axis direction. The number of the clamping devices 30 is determined by the number of groups of the carrying platforms 220, that is, the number of the clamping devices 30 is equal to the number of groups of the carrying platforms 220. When the number is greater than or equal to 2, the clamping devices 30 correspond to the carrying platforms 220 one by one, and different clamping devices 30 correspond to different carrying platforms 220.

[0044] Furthermore, the setting height of the clamping device 30 is certain, and the workpiece 2 to be processed is placed on each carrying plate 221 on the carrying device 20. Since the carrying device 20 can move in a preset direction, the clamping device 30 can clamp the workpiece 2 to be processed at the first end A1 layer by layer and transport it to the second end A2. To illustrate by way of example, first, the driving device 10 maintains the carrying plate 221 on the carrying device 20 at a target height, then, the clamping device 30 clamps the workpiece 2 to be processed on the carrying plate 221 and transports it from the first end A1 to the second end A2, after the transport is completed, the clamping device 30 withdraws from the movement path of the carrying device 20 to avoid obstructing the movement of the carrying device 20, then, the driving device 10 drives the carrying device 20 to rise in a preset direction so that the carrying plate 221 reaches the target height, and maintains the carrying plate 221 at the target height, then, the clamping device 30 clamps the workpiece 2 to be processed on the carrying plate 221 and transports it, and withdraws from the movement path of the carrying device 20 after the transport is completed, then the driving device 10 drives the carrying device 20 to rise again until the clamping device 30 transports the workpiece 2 to be processed on the Mth carrying plate 221 (the last one) from the first end A1 to the second end A2, thereby realizing the process of the clamping device 30 transporting the workpieces 2 to be processed on multiple carrying plates 221 layer by layer.

[0045] In summary, the feeding device 1 provided in the present application includes a driving device 10, a carrying device 20 and a clamping device 30, wherein the driving device 10 is used 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 used to transport the workpiece 2 to be processed on each carrying plate 221 from the first end A1 of the carrying device 20 to the second end A2 layer by layer, thereby realizing 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 in the present application can realize the transportation of multiple workpieces 2 to be processed, thereby meeting the needs of mass production and improving production efficiency.

[0046] As can be seen from the above description, the clamping device 30 can clamp and transport the workpiece 2 to be processed on the carrier plate 221 layer by layer. In this process, the clamping device 30 will at least produce a clamping action and a transport action, and both actions require power consumption to drive. In some special cases, there may be no workpiece 2 to be processed on one or several carrier plates 221. If the clamping device 30 still performs the above two actions, it will lead to a waste of power, especially in mass production, the waste of power is more, so it is necessary to set a device that can detect whether there is a workpiece 2 to be processed on the carrier plate 221. The following is a detailed description of the layout and detection principle of the detection device for detecting the workpiece 2 to be processed.

[0047] Please refer to Figure 4 and Figure 5 In one embodiment, the feeding device 1 further includes a first detection device 40 , the first detection 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 .

[0048] The first sensor 410 is located on one side of the carrying device 20, and is spaced apart from the carrying device 20 and fixedly arranged. The so-called fixed arrangement means that the first sensor 410 does not move with the carrying device 20. Further, the first sensor 410 is arranged opposite to the carrying platform 220, and the number of the first sensors 410 is determined by the number of groups of the carrying platforms 220, that is, the number of the first sensors 410 is equal to the number of groups of the carrying platforms 220. When the number is greater than or equal to 2, the first sensors 410 are opposite to the carrying platforms 220 one by one, and different first sensors 410 are opposite to different carrying platforms 220. Each first sensor 410 is used to detect whether there is a workpiece 2 to be processed on each carrying plate 221 on the corresponding carrying platform 220. The first sensor 410 can be, but is not limited to, an infrared sensor.

[0049] Among them, the second sensor 420 is arranged on one side of the carrying device 20 along the preset direction and is fixedly arranged. The so-called fixed arrangement means that the second sensor 420 is at least partially fixed on other stationary components that are not the carrying device. The second sensor 420 is a distance detection sensor, which is used to obtain the position information of the carrying device 20 in real time. It can be understood that the number of the second sensor 420 is 1 to achieve the above functions. The second sensor 420 can be, but is not limited to, a wire encoder, which includes a wire 421 and a functional body 422 (such as Figure 5As shown in FIG. 1 , the functional body 422 is fixedly arranged and does not move with the carrying device 20. One end of the pull wire 421 is connected to the functional body 422, and the other end of the pull wire 421 is connected to the carrying device 20. When the carrying device 20 moves in a preset direction, the pull wire 421 will stretch, so that the functional body 422 can obtain the real-time position of the carrying device 20. In other embodiments, the second sensor 420 can also be an ultrasonic sensor, an infrared sensor, or other sensor that can measure distance and is spaced apart from the carrying device 20.

[0050] The specific detection principle is as follows: the second sensor 420 is used to obtain the position information of the carrier device 20 and send a first position signal to the processor 440. The processor 440 is used to generate a first control signal after receiving the first position signal. The first control signal is used to control the first sensor 410 to detect whether the workpiece 2 to be processed exists on the carrier plate 221.

[0051] It is understandable that, since the multiple carrier plates 221 in each group of carriers are arranged at intervals, the workpieces 2 to be processed carried on different carrier plates 221 are also arranged at intervals, and only when the workpiece 2 to be processed moves to a position directly opposite to the first sensor 410, the first sensor 410 can detect whether there is a workpiece 2 to be processed on the current carrier plate 221. Therefore, the role of the second sensor 420 is to obtain the position data of the carrier device 20 in the movement process in real time and send it to the processor 440, and the role of the processor 440 is to determine in real time whether the current position of the carrier device 20 satisfies the condition that the workpiece 2 to be processed is directly opposite to the first sensor 410, and if so, the first sensor 410 is controlled to start detection.

[0052] It can be understood that the setting of this embodiment can, firstly, save power by not turning on the first sensor 410 all the time, and secondly, can accurately record which carrier has the workpiece 2 to be processed and which does not, so as to facilitate the subsequent control of whether the clamping device 30 is ready for action.

[0053] Please refer to Figures 6 to 8 In another embodiment, the feeding device 1 further includes a first detection device 40 , the first detection 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 .

[0054] The first sensor 410 is located on one side of the carrying device 20, and is spaced apart from the carrying device 20 and fixedly arranged. The so-called fixed arrangement means that the first sensor 410 does not move with the carrying device 20. Further, the first sensor 410 is arranged opposite to the carrying platform 220, and the number of the first sensors 410 is determined by the number of groups of the carrying platforms 220, that is, the number of the first sensors 410 is equal to the number of groups of the carrying platforms 220. When the number is greater than or equal to 2, the first sensors 410 are opposite to the carrying platforms 220 one by one, and different first sensors 410 are opposite to different carrying platforms 220. Each first sensor 410 is used to detect whether there is a workpiece 2 to be processed on each carrying plate 221 on the corresponding carrying platform 220. The first sensor 410 can be, but is not limited to, an infrared sensor.

[0055] The third sensor 430 is located on one side of the carrying device 20, and is spaced apart from the carrying device 20 and fixedly arranged. The so-called fixed arrangement means that the third sensor 430 does not move with the carrying device 20. The carrying device 20 is provided with a plurality of positioning marks 230 ( Figure 7 The positioning mark 230 may be, but is not limited to, a hole, a groove, a protrusion, etc. The third sensor 430 is used to obtain the position information of the carrying device 20 through the plurality of positioning marks 230. It is understandable that the third sensor 430 can achieve the above function with one. The third sensor 430 may be, but is not limited to, an infrared sensor, an ultrasonic sensor, etc.

[0056] The distance between adjacent carrying plates 221 in the same group of carrying platforms 220 is defined as a first distance. The distance between adjacent positioning marks 230 is defined as a second distance. The first distance and the second distance are equal. Since the positioning mark 230 is set on the carrying device 20, the positioning mark 230 moves the same distance as the carrying device 20 moves, so the current position of the carrying device 20 can be obtained by detecting the position of the mark.

[0057] Optionally, the number of the positioning marks 230 is the same as the number of the carrying plates 221 on the same group of carrying platforms 220 , and the positioning marks 230 and the carrying plates 221 are arranged opposite to each other, and different positioning marks 230 are arranged opposite to different carrying plates 221 .

[0058] The specific detection principle is as follows: the third sensor 430 is used to obtain the position information of the carrier 20 through the multiple positioning marks 230 and send a first position signal to the processor 440. The processor 440 is used to generate a first control signal after receiving the first position signal. The first control signal is used to control the first sensor 410 to detect whether the workpiece 2 to be processed exists on the carrier plate 221.

[0059] As described in the above embodiment, since the multiple carrier plates 221 in each group of carriers are arranged at intervals, the workpieces 2 to be processed carried on different carrier plates 221 are also arranged at intervals, and only when the workpiece 2 to be processed moves to a position directly opposite to the first sensor 410, the first sensor 410 can detect whether there is a workpiece 2 to be processed on the current carrier plate 221. Therefore, the role of the third sensor 430 is to obtain the position data of the carrier device 20 in the process of movement in real time and send it to the processor 440, and the role of the processor 440 is to determine in real time whether the current position of the carrier device 20 satisfies the condition that the workpiece 2 to be processed is directly opposite to the first sensor 410, and if so, control the first sensor 410 to start detection.

[0060] It can be understood that the setting of this embodiment can, firstly, save power by not turning on the first sensor 410 all the time, and secondly, can accurately record which carrier has the workpiece 2 to be processed and which does not, so as to facilitate the subsequent control of whether the clamping device 30 is ready for action.

[0061] It should be noted that in the above two detection implementation modes, the functions of the first sensor 410 and the processor 440 are the same, and the functions of the second sensor 420 and the third sensor 430 are also used to detect the position information of the carrying device 20. The difference is that the second sensor 420 and the third sensor 430 are arranged in different positions, and therefore the detection principles of the second sensor 420 and the third sensor 430 are also different.

[0062] Please refer to Fig. 9 In combination with any of the above detection implementations, the first sensor 410 in the first detection device 40 is used 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 also used to generate a second control signal after receiving the confirmation signal. The second control signal is used to control the clamping device 30 to clamp the workpiece 2 to be processed and transport it from the first end A1 of the carrier device 20 to the second end A2 of the carrier 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 clamping and movement actions. It can be understood that this setting form is conducive to saving power, especially in mass production.

[0063] It should be noted that the inspection process of the workpiece 2 to be processed and the circulation process of the workpiece 2 to be processed can be carried out separately or crosswise. Separately, it means that the first inspection device 40 is used to inspect the carrier device 20 layer by layer, and after the inspection of the entire carrier device 20 is completed, the clamping device 30 is used to rotate the workpiece 2 to be processed on the carrier device 20 layer by layer. Crosswise, it means that the first layer of the carrier device 20 is inspected by the first inspection device 40, and after the inspection of the first layer is completed, the workpiece 2 to be processed on the first layer is rotated by the clamping device 30, and after the operation of the first layer is completed, the first inspection device 40 is used to inspect the second layer in turn, and the clamping device 30 rotates the second layer, and this cycle is repeated until the last layer is completed.

[0064] Optional, see Fig.10 , the carrier plate 221 includes a first carrier plate 2211 and a second carrier plate 2212. The first carrier plate 2211 and the second carrier plate 2212 are spaced apart to form a spacing space B1. The clamping device 30 is at least partially accommodated in the spacing space B1. It is understandable that during the movement of the clamping device 30 clamping the workpiece 2 to be processed, it is necessary to ensure that the movement of the clamping device 30 cannot deviate from the target path, otherwise the workpiece 2 to be processed may not be accurately transferred to the target station. In the present embodiment, the clamping device 30 is at least partially accommodated in the spacing space B1 formed by the first carrier plate 2211 and the second carrier plate 2212, so that the movement of the clamping device 30 can be limited by the first carrier plate 2211 and the second carrier plate 2212, thereby achieving the purpose of preventing the clamping device 30 from deviating from the target path and ensuring that the workpiece 2 to be processed is accurately transferred to the target station.

[0065] As can be seen from the above introduction, when the workpiece 2 is moved from the feeding device 1 to the target station, the accuracy of the position of the workpiece 2 needs to be ensured, so as to ensure that the workpiece 2 can be smoothly moved to the target station and the subsequent processing accuracy can be guaranteed. Figure 3 The feeding device 1 provided in the present application further includes a second detection device 50, which is used to realize positioning of the workpiece 2 to be processed before being moved to the target workstation. The structure, position and positioning principle of the second detection device 50 will be described in detail below in conjunction with the accompanying drawings.

[0066] The second detection device 50 is located at the second end A2 of the carrying device 20, and is spaced apart from the carrying device 20 and fixedly arranged. The so-called fixed arrangement means that the second detection device 50 does not move with the carrying device 20. Further, the second detection device 50 is arranged opposite to the carrying platform 220, and the number of the second detection devices 50 is determined by the number of groups of the carrying platforms 220, that is, the number of the second detection devices 50 is equal to the number of groups of the carrying platforms 220. When the number is greater than or equal to 2, the second detection devices 50 are opposite to the carrying platforms 220 one by one, and different second detection devices 50 are opposite to different carrying platforms 220. Each second detection device 50 is used to realize the positioning of the workpiece 2 to be processed on the corresponding carrying platform 220.

[0067] Please refer to Figures 11 to 13 The second detection device 50 includes a fourth sensor 510 and a positioning plate 520. The positioning plate 520 is fixedly disposed beside the carrying device 20 and adjacent to the second end A2 of the carrying device 20. The fourth sensor 510 is carried on the positioning plate 520.

[0068] The workpiece 2 to be processed includes a main body 22 and a positioning member 21, and the positioning member 21 is protruding from the main body 22. The fourth sensor 510 is used to send a second position signal to the processor 440 when the positioning member 21 on the workpiece 2 to be processed passes through the positioning plate 520. The processor 440 is also used to control the clamping device 30 to stop moving after receiving the second position signal. The position of the workpiece 2 to be processed when the clamping device 30 stops moving is the positioning position, and the workpiece 2 to be processed is in this position to ensure that the workpiece 2 to be processed can be smoothly moved to the target station and to ensure the subsequent processing accuracy.

[0069] Please refer to Figures 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 channel space B2. The channel space B2 is used to accommodate the positioning member 21 on the workpiece 2 to be processed. The first plate 521 is used to be opposite to the first supporting plate 2211. The second plate 522 is used to be opposite to the second supporting plate 2212. The channel space B2 is used to be opposite to the spacing space B1.

[0070] Specifically, the workpiece 2 clamped by the clamping device 30 moves from the first end A1 of the carrying device 20 to the second end A2, and the positioning member 21 on the workpiece 2 is located in the spacing space B1 during this process. Subsequently, the workpiece 2 enters the area where the second detection device 50 is located from the second end A2, and the positioning member 21 on the workpiece 2 enters the channel space B2 from the spacing space B1. It can be understood that during the movement of the workpiece 2, it is necessary to ensure that the movement of the workpiece 2 does not deviate from the target path, otherwise the workpiece 2 may not be accurately transferred to the target station. In this embodiment, the positioning member 21 on the workpiece 2 can enter the channel space B2 formed by the first plate 521 and the second plate 522, so that the movement of the workpiece 2 can be limited by the first plate 521 and the second plate 522, thereby achieving the purpose of preventing the workpiece 2 from deviating from the target path and ensuring that the workpiece 2 is accurately transferred to the target station.

[0071] Please refer to Fig.12 , the second detection device 50 also includes a movable part 540. The movable part 540 is movably connected to the first plate 521 and is at least partially located in the channel space B2. The movable part 540 is used to move after being touched by the positioning part 21 on the workpiece 2 to be processed. The fourth sensor 510 faces one side of the movable part 540. The fourth sensor 510 is used to generate the second position signal after detecting the movement of the movable part 540. In other words, due to the limited size of the channel space B2, the positioning part 21 on the workpiece 2 to be processed will definitely touch the movable part 540 during the movement in the channel space B2. The movable part 540 is movably connected to the first plate 521, so the movable part 540 will move relative to the first plate 521 after being touched by the positioning part 21. The fourth sensor 510 is used to sense whether the movable part 540 moves. If so, the second position signal is sent to the processor 440. After receiving the second position signal, the processor 440 controls the clamping device 30 to stop moving, thereby positioning the workpiece 2 to be processed at the current position, thereby ensuring that the workpiece 2 to be processed can be smoothly moved to the target position and the subsequent processing accuracy is guaranteed. The fourth sensor 510 can be, but is not limited to, a proximity switch, an infrared sensor, an ultrasonic sensor, etc.

[0072] Please refer to Fig.12, the movable member 540 is rotatably connected to the first plate 521. The second detection device 50 also includes an elastic member 530. The elastic member 530 can be, but is not limited to, a spring or the like. One end of the elastic member 530 is fixed to the first plate 521, and the other end is connected to the movable member 540. The elastic member 530 is used to provide elastic force for resetting the movable member 540 after the movable member 540 is touched by the positioning member 21 on the workpiece 2 to be processed and rotates. Specifically, when the movable member 540 is not rotating, the elastic member 530 is in a natural state. When the movable member 540 is collided by the positioning member 21 and transmitted, the elastic member 530 is compressed or stretched by the movable member 540. Therefore, the movable member 540 is subjected to the elastic force of the elastic member 530 to return to the natural state. When the positioning member 21 leaves the movable member 540, the movable member 540 returns to the position when it is not rotating under the action of the elastic force to achieve resetting.

[0073] Please refer to Fig.12 Optionally, the second detection device 50 further includes a first wheel 523 and a second wheel 524. The first wheel 523 is rotatably connected to one end of the first plate 521 close to the carrier 20, and the second wheel 524 is rotatably connected to one end of the second plate 522 close to the carrier 20. The first wheel 523 and the second wheel 524 are arranged at intervals and constitute the entrance B21 of the channel space B2. It can be understood that when the positioning member 21 on the workpiece 2 to be processed passes through the above-mentioned entrance B21 in the process of entering the channel space B2, if the positioning member 21 touches the first wheel 523 or the second wheel 524 in the process of moving forward, the first wheel 523 or the second wheel 524 will rotate without hindering the movement of the positioning member 21. Therefore, the role of the first wheel 523 and the second wheel 524 here is to guide the positioning member 21 to enter the channel space B2 smoothly.

[0074] Please refer to Fig.12 Optionally, the second detection device 50 further includes a third wheel 525 and a fourth wheel 526. The third wheel 525 is rotatably connected to one end of the first plate 521 away from the carrier 20, and the fourth wheel 526 is rotatably connected to one end of the second plate 522 away from the carrier 20. The third wheel 525 and the fourth wheel 526 are arranged at intervals and constitute the exit B22 of the channel space B2. It can be understood that when the positioning member 21 on the workpiece 2 to be processed passes through the above-mentioned exit B22 in the process of exiting the channel space B2, if the positioning member 21 touches the third wheel 525 or the fourth wheel 526 in the process of advancing, the third wheel 525 or the fourth wheel 526 will rotate without hindering the movement of the positioning member 21. Therefore, the role of the third wheel 525 and the fourth wheel 526 here is to guide the positioning member 21 to exit the channel space B2 smoothly.

[0075] Please refer to Fig.12 and Fig.14 , a notch B3 is provided on the positioning plate 520 at a position adjacent to the movable member 540, and the notch B3 is connected to the channel space B2. The second detection device 50 also includes a limiter 550, and the limiter 550 is inserted in the notch B3 and the channel space B2. The limiter 550 is used to block the channel space B2 to hinder the movement of the positioning member 21 on the workpiece 2 to be processed, thereby ensuring that the workpiece 2 to be processed can stop moving in time after being detected by the fourth sensor 510. It can be seen from the previous description that after the fourth sensor 510 detects the workpiece 2 to be processed, the processor 440 will control the clamping device 30 to stop moving. However, in actual situations, both the workpiece 2 to be processed and the clamping device 30 have a certain inertia, and the control effect also has a certain delay. Therefore, the workpiece 2 to be processed will not stop in time. The limiter 550 provided in this embodiment can solve the problem that the workpiece 2 to be processed cannot stop in time, thereby ensuring the accuracy of subsequent actions.

[0076] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present application, and these improvements and modifications are also regarded as the scope of protection of the present application.
