[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0024] The terms "first", "second", and the like in the description and in the claims of the present application are used for distinguishing between similar objects and are not necessarily used to describe a particular sequential or chronological order. It is to be understood that the use of the term "and / or", "or", and the like, for example, in the cases of "X and / or Y" and "X or Y" and "X, Y, and / or Z", is intended to encompass the selection of either X or Y or Z of the alternatives, or the selection of multiple one of X and Y, or variations thereof, such as Y and / or including X. Such disjunctive language shall

[0025] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and specific embodiments and application scenarios thereof.

[0026] Reference Figures 1 to 5 The embodiments of the present application disclose a screw feeding system, applied to a screw assembly process. The disclosed screw feeding system comprises a feeding device 10, a recycling device 20 and a control device 30.

[0027] The feeding device 10 is used to supply the screws to be assembled. In some embodiments, the screws can be assembled to the product in a manual or automatic manner to complete the assembly of the product. Exemplarily, the screws can be screwed by an electric screwdriver 42, and of course, other ways can also be used to realize the assembly of the screws.

[0028] The recycling device 20 is used to recycle the screws with assembly abnormalities. As shown in Figure 3 and Figure 4 In some embodiments, the recycling device 20 comprises a recycling container 21 and a detection element 22, and the detection element 22 is arranged in the recycling container 21 and used to detect whether the screws with assembly abnormalities enter the recycling container 21.

[0029] It should be noted that in the assembly process of the screws, there may be a situation of screw assembly abnormalities, which causes the screws to fall off the product. In this case, the product is easily disturbed by the screws and affects the normal operation, and also brings a bad impression to the customers. Therefore, the screws with assembly abnormalities need to be recycled to prevent the screws from falling off the product.

[0030] Based on the above situation, the screws with assembly abnormalities need to be recycled. Specifically, the screws with assembly abnormalities can be placed in the recycling container 21, and the detection element 22 is used to detect to ensure that the screws with assembly abnormalities are placed in the recycling container 21 and will not be left on the product.

[0031] Furthermore, whether the screw assembly is abnormal can be fed back based on the torque parameters of the electric screwdriver 42. Specifically, when the torque of the electric screwdriver 42 reaches the preset torque for normal assembly, it indicates that the screw assembly is normal; conversely, when the torque of the electric screwdriver 42 does not reach the preset torque for normal assembly, it indicates that the screw assembly is abnormal. Therefore, for each screw supplied by the feeding device 10, the electric screwdriver 42 needs to reach the preset torque. If, during a certain assembly process, the torque of the electric screwdriver 42 does not reach the preset torque, the screw corresponding to that assembly process needs to be recycled into the recycling container 21 and detected by the detection element 22 to ensure that the screw is recycled, thereby ensuring that the screw is not left on the product.

[0032] To control the screw supply and detect screws with assembly defects, in this embodiment, the control device 30 is electrically connected to the feeding device 10 and the detection element 22, respectively. When the detection element 22 detects a screw with assembly defects entering the recycling container 21, the control device 30 controls the feeding device 10 to output a new screw. The control device 30 collects input signals, processes logic, and controls output signals; its specific working principle can be found in related technologies and will not be elaborated here. For example, the control device 30 may include a PLC.

[0033] Based on this process, it can be ensured that each screw output by the feeding device 10 is properly assembled into the product or placed into the recycling container 21, so that each screw will not be lost or dropped, and that the screws will not be taken away at will.

[0034] Therefore, the screw feeding system in this application embodiment can not only supply screws to be assembled, but also recycle screws that are improperly assembled. A new screw can only be supplied after successful recycling. This can prevent personnel from taking screws at will and effectively alleviate the problem of screws that are improperly assembled falling onto the product and causing product quality problems.

[0035] refer to Figure 4 In some embodiments, the recycling container 21 may include a housing 211 and a receiving member 212 disposed within the housing 211. The housing 211 is a basic component, providing both an installation base for the receiving member 212 and a place to accommodate the screws with assembly defects to be recycled. The top of the housing 211 may have an inlet 2111 through which the screws with assembly defects can enter the inner cavity of the housing 211 for recycling. Exemplarily, the inlet 2111 may be located on the top wall of the housing 211; alternatively, it may be located on the side wall of the housing 211 near the top wall, as long as the screws with assembly defects can enter the inner cavity of the housing 211. The specific location is not limited.

[0036] In addition, a hopper 2112 can be arranged on the top of the shell 211 to facilitate the screws to enter the feeding port 2111. The cross-sectional area of the hopper 2112 at the end away from the feeding port 2111 is greater than that at the end close to the feeding port 2111 to facilitate the screws to enter.

[0037] The receiving member 212 can be arranged below the feeding port 2111. Thus, the screws entering the shell 211 through the feeding port 2111 can contact the receiving member 212 to facilitate the receiving, buffering and guiding of the screws entering the cavity of the shell 211.

[0038] Optionally, the receiving member 212 can include a receiving surface 2121 which forms an angle with the horizontal plane. The angle between the receiving surface 2121 and the horizontal plane can be 10° to 80°, for example, 10°, 15°, 20°, 30°, 40°, 45°, 60°, 80°, etc. Of course, other angles can also be used. In this way, the receiving member 212 can form a slope to facilitate the smooth downward movement of the screws along the receiving surface 2121, thereby achieving the receiving, buffering and guiding of the screws.

[0039] In addition, the receiving surface 2121 is arranged opposite to the feeding port 2111 to receive the screws entering the shell 211 through the feeding port 2111, thereby preventing the screws from directly falling into the bottom of the shell 211 to cause large vibration and noise.

[0040] In some embodiments, at least part of the detection element 22 is arranged in the shell 211 to detect the screws entering the shell 211 and count the screws to ensure the accurate recovery of the abnormal screws.

[0041] The detection element 22 can include a passing port 221 arranged below the lower end of the receiving surface 2121. In this way, the screws moving along the receiving surface 2121 can fall from the lower end of the receiving surface 2121 and enter the passing port 221. When the screws pass through the passing port 221, the screws can be detected and counted.

[0042] The detection element 22 can be a photoelectric sensor which can include a light emitter and a light receiver. The light emitter and the light receiver can be arranged on the side walls of the passing port 221 and arranged opposite to each other. Thus, when the screws pass through the passing port 221, the screws can block the light, so that the light receiver cannot receive the light emitted by the light emitter, thereby determining that the screws pass through the passing port 221 to achieve the detection and counting of the screws.

[0043] Of course, the detection element 22 can also be other types of sensors as long as it can detect and count the screws, and the specific form is not limited.

[0044] In some embodiments, the distance between the feed port 2111 and the passing port 221 is relatively large, in which case the recovery container 21 can include a plurality of receiving members 212 arranged between the feed port 2111 and the passing port 221, so that the screws entering the shell 211 through the feed port 2111 can be received by the plurality of receiving members 212 layer by layer, and finally fall through the passing port 221 to the bottom of the recovery container 21, and detection and counting of the recovered screws are achieved.

[0045] Among the plurality of receiving members 212, the receiving surface 2121 of the uppermost receiving member 212 (i.e., closest to the feed port 2111) is arranged opposite to the feed port 2111, so as to receive the screws entering through the feed port 2111 and guide the screws through the receiving surface 2121 to move obliquely downward; among the adjacent two receiving members 212, the lower end of the upper receiving member 212 is located above the receiving surface 2121 of the lower receiving member 212, so that the screws can fall from the lower end of the receiving surface 2121 of the upper receiving member 212 to the receiving surface 2121 of the lower receiving member 212, and so on, so that the screws finally fall onto the receiving surface 2121 of the lowermost receiving member 212; the lower end of the lowermost receiving member 212 is located above the passing port 221, so that the screws can fall through the lower end of the receiving surface 2121 of the lowermost receiving member 212 to the passing port 221, so as to be detected and counted by the detection element 22, and finally fall to the bottom of the shell 211 to be recovered.

[0046] Continuing to refer to Figure 4 In some embodiments, the shell 211 can include a first side wall and a second side wall arranged at intervals, and among the adjacent two receiving members 212, one is connected to the first side wall and the other is connected to the second side wall. Based on this arrangement, the plurality of receiving members 212 can be arranged in sequence and cross each other, so that the movement path of the screws is in the shape of a broken line, thereby effectively reducing the distance of the shell 211 in the direction from the first side wall to the second side wall, and further reducing the volume of the shell 211 and saving materials.

[0047] In addition, the outer wall of the recovery container 21 can also be provided with a display screen, which is electrically connected to the control device 30, so as to display the number of abnormally assembled screws recovered in the recovery container 21 through the display screen. Based on this, the number of abnormally assembled screws assembled by each worker can be known through the number, which can provide some data basis for performance evaluation.

[0048] Reference Figure 5 In some embodiments, the screw supply system can further comprise an electric screwdriver controller 41 for detecting and controlling the electric screwdriver 42 to determine whether the screw is assembled normally. The electric screwdriver controller 41 can be electrically connected to the electric screwdriver 42, and the electric screwdriver 42 can be controlled and its operation can be detected through the electric screwdriver controller 41, which can ensure the normal operation of the electric screwdriver 42 and obtain the operation parameters of the electric screwdriver 42. Thus, the torque of the electric screwdriver 42 can be detected and obtained in real time through the electric screwdriver controller 41, so as to reflect whether the screw is assembled normally through the torque of the electric screwdriver 42. It should be noted that the specific structure and working principle of the electric screwdriver 42 and the specific structure and working principle of the electric screwdriver controller 41 can be referred to the prior art, which will not be described in detail here.

[0049] In the embodiments of the present application, the control device 30 is electrically connected to the electric screwdriver controller 41, and is used to control the supply device 10 to output a new screw when the electric screwdriver controller 41 determines that the screw is assembled normally. Based on this, it can be ensured that the supply device 10 will not output a new screw at will, thereby preventing the situation that the worker takes the screw at will in the case that the last screw is assembled abnormally, and further preventing the situation of screw loss, falling into the product, and waste from occurring.

[0050] Of course, the screw can also be assembled abnormally, in which case the control device 30 is further used to control the supply device 10 to output a new screw when the electric screwdriver controller 41 determines that the screw is assembled abnormally and the detection element 22 detects that the abnormally assembled screw enters the recycling container 21. Based on this, in the case that the screw is assembled abnormally, it can be ensured that the screw will not be lost or fall into the product, but will be recycled, otherwise, the supply device 10 will not output a new screw, thus, the specific situation of each screw output by the supply device 10 can be determined, such as being normally assembled, being abnormally assembled and being recycled, thereby preventing the situation of falling unknown.

[0051] In addition, the control device 30 is further used to control the supply device 10 to stop outputting a new screw when the electric screwdriver controller 41 determines that the screw is assembled abnormally and the detection element 22 does not detect that the abnormally assembled screw enters the recycling container 21. Based on this, it can effectively prevent the situation that the new screw is output at will and taken by the worker at will.

[0052] Reference Figure 1In some embodiments, the screw feeding system can further include a flow channel 50 for conveying the product to which the screw is to be assembled. The flow channel 50 can include a flow channel body 51, which can be a belt conveyor, a roller conveyor, a push plate conveyor, or the like, and can also be in other forms, which are not limited herein as long as the product can be conveyed.

[0053] In addition, the flow channel 50 can further include a first code scanner 52 for scanning the product conveyed in the flow channel 50 to obtain specific parameter information of the product. The first code scanner 52 can be arranged on the flow channel body 51, for example, on the side of the flow channel body 51, on the bottom of the flow channel body 51, on the top of the flow channel body 51, or the like, as long as the information of the product can be scanned, and the specific arrangement form is not limited.

[0054] The flow channel body 51 can be provided with an assembly station 511, and the product conveyed to the assembly station 511 can be assembled with the screw. The first code scanner 52 can be arranged at the assembly station 511.

[0055] In the embodiments of the present application, the control device 30 can be electrically connected with the first code scanner 52, and used to determine the target number of screws to be assembled on the product according to the scanning result of the first code scanner 52. It should be noted that the control device 30 can be pre-set with parameter information of different products, for example, a first number of screws are to be assembled on a first product, a second number of screws are to be assembled on a second product, and the like, and the specification of the required screw can also be determined according to the scanning.

[0056] Based on the above, after the product is conveyed to the assembly station 511 by the flow channel body 51, the parameter information of the product can be scanned by the first code scanner 52, and the parameter information can be sent to the control device 30, so as to obtain the target number of screws to be assembled on the product. Therefore, in the subsequent screw assembly process, the number of screws output by the feeding device 10 needs to be ensured to be equal to the target number, so as to avoid the situation that the screws are supplied too much or too little.

[0057] Considering that the product conveyed to the assembly station 511 by the flow channel body 51 needs to be assembled with the screw, it is necessary to ensure that the product does not move randomly during the screw assembly process, and the product needs to be conveyed downstream after the assembly is completed. Based on this, the screw feeding system in the embodiments of the present application can further include a blocking device 60, for example, Figure 1As shown, the product can be limited in the assembly station 511 by the blocking device 60 after reaching the assembly station 511 and cannot continue to transmit downstream, ensuring that the product can be assembled with screws in the assembly station 511; after the product is assembled with screws, the product can be released to continue to transmit downstream.

[0058] As shown, the blocking device can include a baffle 61 and a driving mechanism 62, the baffle 61 is connected with the driving mechanism 62, and the baffle 61 is slidingly connected with the assembly station 511. Thus, the baffle 61 can be moved relative to the assembly station 511 by the driving mechanism 62 to block or release the product in the assembly station 511. Figure 1

[0059] Exemplarily, the driving mechanism 62 can be a linear driving mechanism, which can drive the baffle 61 to move along a straight line to move the baffle 61 into or out of the assembly station 511; the driving mechanism 62 can also be a rotary driving mechanism, which can drive the baffle 61 to move along an arc to move the baffle 61 into or out of the assembly station 511.

[0060] In the embodiment, the control device 30 is electrically connected with the driving mechanism 62, and is configured to control the driving mechanism 62 to drive the baffle 61 to move out of the assembly station 511 when the number of screws reaches the target number, so that the assembled product moves along the flow channel 50 to the downstream. Based on this, it can be ensured that the product will not be under-screwed, thereby ensuring the assembly quality of the product.

[0061] Referring to Figure 2 In some embodiments, the feeding device 10 can include a tank 11 and a feeder 12, the tank 11 is used to accommodate screws to be assembled, and the feeder 12 is arranged in the tank 11 and is used to output the screws in the tank 11. Exemplarily, the feeder 12 can adopt a screw rod feeding mode, that is, the screws in the tank 11 are pushed out by the rotation of the screw rod to realize feeding. Specifically, the feeder 12 includes a motor and a screw rod, the screw rod is drivingly connected with the motor to rotate by the motor, and the screw rod drives the screws to move by the rotation. Of course, other feeding modes can also be adopted, which are not limited here.

[0062] ​In addition, the magazine 11 can include a box body 111, a box cover 112 connected to the box body 111 and openable or closable relative to the box body 111, and a lock body 113 for locking the box cover 112 and the box body 111, so that the box cover 112 is locked with the box body 111 by the lock body 113 without the need for additional screws, to prevent the box cover 112 from being opened at will, thereby ensuring that the screws in the magazine 11 cannot be taken at will. In the case of needing to replenish screws, the lock body 113 can be opened, and the box cover 112 can be opened to replenish the screws.

[0063] To achieve automatic opening of the lock body 113, the magazine 11 can further include a second code scanner 114 provided on the box body 111, and the control device 30 is electrically connected with the second code scanner 114 and the lock body 113, for controlling the lock body 113 to be opened when the second code scanner 114 scans the corresponding product and screws. Based on this arrangement, the box cover 112 can only be unlocked and opened when the scanning information of the product and the screws matches, so that the unlocking can be facilitated, and the situation that the screws are taken at will by directly opening the box cover 112 by the worker can be effectively prevented.

[0064] With reference to the foregoing Figure 2 In some embodiments, the feeding device 10 can further be provided with a data reset button 13 electrically connected with the control device 30, and the control device 30 is configured to control the feeding device 10 to clear data when receiving data clearing information of the data reset button 13. Based on this, the counting can be restarted in the case of abnormality in the assembly process, to ensure the normal progress of the next assembly process. For example, the data reset button 13 can be arranged on the outer wall of the magazine 11 of the feeding device 10, and of course, can also be arranged at other positions to facilitate the operation of the operator.

[0065] In the actual assembly process, when the screws are assembled to half of the target number, the product needs to be removed due to abnormality, in which case, the data reset button 13 can be pressed lightly or for a long time to send a data clearing instruction to the control device 30, and the control device 30 clears the counting information of the number of screws in this process after receiving the instruction, so that the next assembly process is not affected.

[0066] With reference to the foregoing Figure 2In some embodiments, the feeding device 10 can further be provided with a first warning light 14, which is electrically connected with the control device 30, and the control device 30 is configured to control the first warning light 14 to light up when the number of screws output by the feeding device 10 reaches the target number of screws required for assembling the product. Based on this, the staff can be reminded that the product has been assembled, and the blocking device 60 can be removed from the product to enable the product to move downstream. Exemplarily, the first warning light 14 can be a green light, and of course, other colors are also possible.

[0067] In some embodiments, the feeding device 10 can further be provided with a second warning light 15, which is electrically connected with the control device 30, and the control device 30 is configured to control the second warning light 15 to light up when the number of screws in the feeding device 10 is less than the preset minimum number. Based on this, the staff can be reminded to replenish the screws in time when the number of screws in the feeding device 10 is insufficient.

[0068] It should be noted here that the initial number of screws in the feeding device 10 and the preset minimum number can be set in the control device 30, and the control device 30 can count the number of screws output, so that the control device 30 can know the real-time number of screws in the feeding device 10, and when the real-time number is less than the minimum number, the second warning light 15 lights up to prompt.

[0069] Exemplarily, the second warning light 15 can be a green light, and of course, other colors are also possible.

[0070] In addition, the first warning light 14 and the second warning light 15 can be arranged on the outer wall of the tank 11 of the feeding device 10, so as to be easily observed by the staff.

[0071] In the embodiments of the present application, the working process of the screw feeding system is as follows:

[0072] The product can be placed in the channel body by the carrier, and the blocking device 60 limits the product in the assembly station 511, and the first code scanner 52 scans the product, and then sends the scanning information to the control device 30. After the scanning information matches the preset product information in the control device 30 successfully, the control device 30 controls the feeding device 10 to output a screw, so that the staff can take it away and assemble it to the product by the electric screwdriver 42. During this process, the control device 30 counts the number of output screws.

[0073] The electric screwdriver controller 41 obtains the torque of the electric screwdriver 42 in real time. When the torque reaches the preset torque, it is determined that the screw is assembled normally, and a signal of normal screw assembly is sent to the control device 30. After the control device 30 receives the signal of normal screw assembly, it controls the feeding device 10 to output a new screw. When the torque does not reach the preset torque, it is determined that the screw is assembled abnormally, and a signal of abnormal screw assembly is sent to the control device 30. The worker can place the abnormally assembled screw into the recycling device 20. When the detection element 22 detects that the abnormally assembled screw enters the recycling container 21, a first signal is sent to the control device 30, and the control device 30 controls the feeding device 10 to output a new screw. On the contrary, when the torque does not reach the preset torque and the detection element 22 does not detect that the abnormally assembled screw enters the recycling container 21, a second signal is sent to the control device 30, and the control device 30 controls the feeding device 10 to stop outputting the screw until the screw is placed into the recycling container 21, and then the new screw can be continuously outputted.

[0074] Similarly, until the number of assembled screws reaches the target number.

[0075] When the number of assembled screws reaches the target number, the control device 30 controls the first warning light 14 to turn on to remind the worker that the screws of the product have been assembled. At this time, the worker can input a command to release the restriction, such as pressing the double-acting switch with both hands. After the control device 30 receives the command, it controls the blocking device 60 to release the limiting action on the product, so that the product can be transported to the downstream.

[0076] The control device 30 clears the feeding data of the feeding device 10 and the recycling data of the recycling device 20, and waits for the next product to assemble screws.

[0077] The above processes are repeated until the number of screws in the feeding device 10 is reduced to the minimum number. At this time, the second warning light 15 turns on to remind the worker to replenish the screws.

[0078] In summary, the screw feeding system in the embodiment of the application can control the output number of screws, ensure that the corresponding number of screws for each product is outputted, alleviate the trouble caused by the loss and falling of screws, and improve the convenience of the worker's operation, and it is not easy to take the wrong screws and drop the screws. By locking the feeding device 10, the worker can avoid taking the screws at will.

[0079] The embodiments of the present application are described above with reference to the accompanying drawings, but the present application is not limited to the specific embodiments described above, and the specific embodiments described above are merely illustrative, but not restrictive, and a person of ordinary skill in the art can make many forms under the inspiration of the present application without departing from the purpose of the present application and the scope protected by the claims.
