Description

Technical Field

[0001] The present application relates to the technical field of processing equipment, and in particular to a screw locking device. Background Art

[0002] In the related art, screw locking equipment can lock screws into the holes of the parts to be assembled to form an assembly. However, existing screw locking equipment cannot identify burrs on the parts to be assembled (especially burrs formed at the bottom nozzle of the screwed product), resulting in inaccurate positioning of the parts to be assembled, affecting the subsequent screw locking process. It can also cause the assembled assembly to be easily scratched by the burrs when it is subsequently assembled with other soft components such as fabric, resulting in a low product yield. Utility Model Content

[0003] The embodiment of the present application provides a screw locking device, which can solve the problem in the related art that the screw locking device cannot identify whether there are burrs on the assembled parts, thereby affecting the subsequent screw locking process and resulting in low product yield.

[0004] An embodiment of the present application provides a screw locking device; the screw locking device includes a frame, a jig module, a conveying module and a locking module, the jig module includes a jig and a detection component, the jig is used to carry and fix the part to be assembled, the detection component is arranged on the jig, the conveying module is installed on the frame and connected to the jig, the conveying module is configured to drive the jig to move along a first direction so that the jig switches between a preset loading position and a preset unloading position, when the jig is in the preset loading position, the detection component is configured to detect whether there is a burr at the water outlet of the part to be assembled after the part to be assembled is fixed on the jig, the locking module is installed on the frame, and the locking module is configured to lock the screw in the hole position of the part to be assembled to assemble to form an assembly when the detection component does not detect the presence of a burr at the water outlet of the part to be assembled.

[0005] Based on the screw locking device of the embodiment of the present application, when the jig is in the preset loading position, the operator places the part to be assembled on the jig. After the part to be assembled is fixed by the jig, the detection component detects whether there are burrs at the outlet of the configuration to be assembled. If the detection component does not detect the burr, the locking module will lock the screw into the hole of the part to be assembled to form an assembly. Then the conveying module drives the jig carrying the assembly to move along the first direction to the preset unloading position to perform the unloading operation. By designing the detection component, the detection component can detect the part to be assembled to determine whether there are burrs on the part to be assembled. If the detection component detects burrs, the operator can remove the part to be assembled with burrs from the jig and manually or automatically deburr the removed part to be assembled. Then, the deburred part to be assembled is placed back in the jig. This can effectively reduce or even avoid the possibility of inaccurate positioning of the part to be assembled due to burrs, which affects the subsequent screw locking process, and reduce or even avoid the possibility of burrs scratching the fabric in the subsequent process, which can effectively improve the product yield.

[0006] In some embodiments, the detection component generates a warning signal when it detects a burr at the nozzle of a component to be assembled. The screw fastening device also includes a warning module and a control module; the warning module is configured to issue a warning prompt; the control module is mounted on the frame, electrically connected to the detection component, and configured to control the warning module to issue a warning prompt based on the warning signal.

[0007] Based on the above embodiment, by designing a control module and an early warning module, when the detection component detects the presence of burrs at the water outlet of the part to be assembled, a early warning signal is generated. The control module controls the early warning module to issue an early warning prompt according to the early warning signal. The operator can then remove the part to be assembled with burrs carried on the jig in time according to the early warning prompt, and perform manual or mechanical automatic deburring on the removed part to be assembled, and then place the deburred part to be assembled back into the jig. This can effectively reduce or even avoid the possibility of inaccurate positioning of the part to be assembled due to burrs, thereby affecting the subsequent screw locking process, and reduce or even avoid the possibility of burrs scratching the fabric in the subsequent process, thereby effectively improving the product yield.

[0008] In some embodiments, the jig includes a jig body and a first positioning assembly; the jig body is used to support the part to be assembled and is connected to the conveying module; the first positioning assembly is mounted on the jig body and is used to secure the part to be assembled supported on the jig body to the jig body. The detection assembly includes a first sensor; the first sensor is disposed on the jig body and is electrically connected to the control module, and is used to detect whether there are burrs at the sprue of the part to be assembled after the first positioning assembly secures the part to be assembled to the jig body.

[0009] Based on the above embodiment, a first sensor is designed, which is used to detect whether there are burrs at the water outlet of the part to be assembled after the first positioning component fixes the part to be assembled on the fixture body; if the first sensor detects that there are burrs at the water outlet of the part to be assembled, it generates the above-mentioned warning signal, and the control module controls the warning module to make a warning prompt according to the warning signal. At this time, the operator can remove the part to be assembled with burrs on the fixture body in time according to the warning prompt, and perform manual or mechanical automatic deburring on the removed part to be assembled, and then replace the deburred part to be assembled in the fixture body. This can effectively reduce or even avoid the possibility of inaccurate positioning of the part to be assembled due to burrs, thereby affecting the subsequent screw locking process, and reduce or even avoid the possibility of burrs scratching the fabric in the subsequent process, which can effectively improve the product yield.

[0011] Based on the above embodiment, when the jig body is in the above-mentioned preset loading position, the driving end of the first driving member drives the first positioning member to move along the second direction toward the part to be assembled until it is tightly pressed against the part to be assembled, so that the part to be assembled is fixed to the fixture body. Then the first sensor can detect whether there is burr on the water outlet of the part to be assembled. If so, the first sensor generates an early warning signal, and the control module controls the early warning module to issue an early warning prompt according to the early warning signal. The driving end of the first driving member drives the first positioning member to move along the second direction back to the part to be assembled until it is separated from the part to be assembled. At this time, the operator can remove the part to be assembled with burrs carried on the jig body, and perform manual or mechanical automatic deburring on the removed part to be assembled, and then replace the deburred part to be assembled in the jig body. The driving end of the first driving member drives the first positioning member to move along the second direction toward the part to be assembled until it is tightly pressed against the part to be assembled, so that the part to be assembled is fixed to the fixture body again, so that the subsequent locking module can perform a locking operation on the part to be assembled.

[0014] In some embodiments, the jig further includes a second positioning component, which is mounted on the jig body and is used to press the part to be assembled fixed to the jig body along the first direction; and / or, the jig further includes a third positioning component, which is mounted on the jig body and is used to press the part to be assembled fixed to the jig body along a third direction; the third direction intersects with the first direction.

[0015] Based on the above embodiment, the second positioning assembly is used to press the part to be assembled against the jig body in a first direction, thereby achieving multi-directional fixation of the part to be assembled, which can effectively enhance the stability of the part to be assembled against the jig body. The third positioning assembly is used to press the part to be assembled against the jig body in a third direction, thereby achieving multi-directional fixation of the part to be assembled, which can effectively enhance the stability of the part to be assembled against the jig body.

[0016] In some embodiments, the second positioning assembly includes a second driving member and a second positioning member, the second driving member is mounted on the fixture body, the second positioning member is mounted on the driving end of the second driving member, and the driving end of the second driving member is movable in a first direction to drive the second positioning member to move in the first direction until it is in close contact with the part to be assembled.

[0017] Based on the above embodiment, when the jig body is in the above-mentioned preset loading position, the driving end of the second driving member first drives the second positioning member to move along the first direction toward the part to be assembled until it is pressed against the part to be assembled, and the driving end of the first driving member then drives the first positioning member to move along the second direction toward the part to be assembled until it is pressed against the part to be assembled. In this way, the second positioning member cooperates with the first positioning member to achieve multi-directional fixation of the part to be assembled, which can effectively enhance the connection stability between the part to be assembled and the jig body.

[0039] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0040] Please refer to Figure 1-Figure 4 As shown, the present application proposes a screw locking device 1, which can effectively detect burrs 2b on the part to be assembled 2, can achieve accurate positioning of the part to be assembled 2 and can effectively improve product yield.

[0041] The screw locking device 1 includes a frame 10, a jig module 20, a conveying module 30 and a locking module 40. The jig module 20 includes a jig 21 and a detection component 22; the jig 21 is used to carry and fix the part to be assembled 2; the detection component 22 is arranged on the jig 21. The conveying module 30 is installed on the frame 10 and connected to the jig 21. The conveying module 30 is configured to drive the jig 21 to move along the first direction OO' so that the jig 21 switches between a preset loading position and a preset unloading position; when the jig 21 is in the preset loading position, the detection component 22 is configured to detect whether there is a burr 2b at the sprue 2a of the part to be assembled 2 after the part to be assembled 2 is fixed to the jig 21. The locking module 40 is installed on the frame 10. The locking module 40 is configured to lock the screw into the hole of the part to be assembled 2 to assemble to form an assembly when the detection component 22 does not detect the presence of a burr 2b at the sprue 2a of the part to be assembled 2.

[0042] The following combination Figures 1-13 The specific structure of the screw locking device 1 is introduced in detail.

[0043] like Figure 1-Figure 4 As shown, the screw fastening device 1 includes a frame 10 , a fixture module 20 , a conveying module 30 and a fastening module 40 .

[0044] The frame 10 serves as the main body of the screw fastening device 1. The specific structure of the frame 10 is not limited here, and designers can design it based on actual needs. For example, the frame 10 includes a workbench 11 and a cover. The fixture module 20, conveying module 30, and fastening module 40 are all mounted on the workbench 11. The cover is connected to the workbench 11 and covers the workbench 11 surface. The cover can be a semi-enclosed structure with an opening on one side, or a fully enclosed structure with a door on one side.

[0045] The fixture module 20 serves as a supporting mechanism for the screw fastening device 1 . The fixture module 20 includes a fixture 21 and a detection component 22 .

[0046] The jig 21, as a fixture in the jig module 20, is used to support and secure the component 2 to be assembled. This means that the jig 21 not only supports the component 2 to be assembled but also positions the component 2 to be assembled. The specific structure of the jig 21 will be described in detail below. The component 2 to be assembled can include, but is not limited to, the base of a stroller.

[0047] Detection assembly 22, as the detection structure of jig module 20, is used to detect the presence of burrs 2b at the sprue 2a of the component 2 to be assembled. The specific form of detection assembly 22 will be described in detail below. The sprue 2a, also known as the "injection port," is the interface through which the injection molding machine injects the melt of plastic pellets into the mold during the production of a plastic product. It is understood that if an excessive amount of melt is injected, burrs 2b, such as protrusions, can easily form at the sprue 2a after the melt in the mold cools and forms.

[0048] like Figure 1-Figure 4 As shown, the detection component 22 is disposed on the fixture 21. The specific connection method between the detection component 22 and the fixture 21 is not limited here, and designers can reasonably design it according to actual needs. For example, the detection component 22 can be, but is not limited to, detachably connected to the fixture 21 by at least one of screw connection, clip connection, or plug connection. For another example, the detection component 22 can also be, but is not limited to, non-detachably connected to the fixture 21 by gluing.

[0049] The conveying module 30 serves as a transmission mechanism of the screw fastening device 1 . The specific structure of the conveying module 30 will be described in detail below.

[0050] The conveyor module 30 is mounted on the frame 10. The specific connection method between the conveyor module 30 and the frame 10 is not limited here, and designers can reasonably design it according to actual needs. For example, the conveyor module 30 can be, but is not limited to, detachably connected to the frame 10 by at least one of screwing, snapping, or plugging. For another example, the conveyor module 30 can also be, but is not limited to, non-detachably connected to the frame 10 by welding or riveting.

[0051] The conveying module 30 is connected to the jig 21, which is mounted on the driving end of the conveying module 30. The specific connection method between the jig 21 and the driving end of the conveying module 30 is not limited here, and designers can reasonably design it according to actual needs. For example, the jig 21 can be, but is not limited to, a detachable connection to the driving end of the conveying module 30 through at least one of a screw connection, a snap connection, or a plug-in connection. For another example, the jig 21 can also be, but is not limited to, a non-detachable connection to the driving end of the conveying module 30 through welding or riveting.

[0052] The conveying module 30 is configured to drive the jig 21 to move along the first direction OO' so that the jig 21 switches between a preset loading position and a preset unloading position. The "preset loading position" is the position of the jig 21 when the operator places the part 2 to be assembled into the jig 21 (e.g., Figure 1The “preset blanking position” is the position of the fixture 21 when the blanking module 50 (described below) performs blanking operations on the assembly of screws and assembly parts.

[0053] When the jig 21 is in the preset loading position, the inspection assembly 22 is configured to inspect the sprue 2a of the component 2 for burrs 2b after the component 2 is secured to the jig 21. It should be noted that when the component 2 is supported on the jig 21 and not secured to the jig 21, the inspection assembly 22 will not inspect the sprue 2a of the component 2.

[0054] The locking module 40 serves as a locking mechanism of the screw locking device 1 for locking the screw in the hole of the component 2 to be assembled. The specific structure of the locking module 40 will be described in detail below.

[0055] The locking module 40 is mounted on the frame 10. The specific connection method between the locking module 40 and the frame 10 is not limited herein, and designers may reasonably design it based on actual needs. For example, the locking module 40 may be, but is not limited to, detachably connected to the frame 10 via at least one of screwing, snapping, or plugging. For another example, the locking module 40 may be, but is not limited to, permanently connected to the frame 10 via welding or riveting.

[0056] The locking module 40 is configured to lock the screws into the holes of the component 2 to be assembled to form the assembly when the detection assembly 22 does not detect the presence of burrs 2b at the nozzle 2a of the component 2 to be assembled. After the locking module 40 locks the screws into the holes of the component 2 to form the assembly, the conveying mechanism drives the jig 21 in the first direction OO' to move the jig 21 to a preset unloading position so that the unloading module 50 can perform the unloading operation. After the unloading module 50 removes the assembly from the jig 21, the conveying module 30 drives the jig 21 in the first direction OO' to move the jig 21 to the preset loading position.

[0057] Based on the screw locking device 1 in the embodiment of the present application, when the jig 21 is in the preset loading position, the operator places the part to be assembled 2 on the jig 21. After the part to be assembled 2 is fixed by the jig 21, the detection component 22 detects whether there is a burr 2b at the sprue 2a to be assembled. If the detection component 22 does not detect the burr 2b, the locking module 40 locks the screw in the hole of the part to be assembled 2 to form an assembly. Then the conveying module 30 drives the jig 21 carrying the assembly to move along the first direction OO' to the preset unloading position to perform the unloading operation. By designing the detection component 22, the detection component 22 can detect the part to be assembled 2 to determine whether there is a burr 2b on the part to be assembled 2. If the detection component 22 detects the burr 2b, the operator can remove the part to be assembled 2 with the burr 2b from the jig 21, and manually or mechanically remove the burrs 2b on the removed part to be assembled 2, and then replace the part to be assembled 2 with the burrs 2b removed into the jig 21. This can effectively reduce or even avoid the possibility of inaccurate positioning of the part to be assembled 2 due to the burr 2b, thereby affecting the subsequent screw locking process, and reduce or even avoid the possibility of the burr 2b scratching the fabric in the subsequent process, thereby effectively improving the product yield.

[0058] like Figure 1-Figure 4 As shown, the detection assembly 22 generates a warning signal when it detects a burr 2b at the nozzle 2a of the assembly 2. The screw fastening device 1 also includes a warning module (not shown) and a control module (not shown). The warning module is configured to issue a warning prompt. The control module is mounted on the frame 10 and is electrically connected to the detection assembly 22. The control module is configured to control the warning module to issue a warning prompt based on the warning signal.

[0059] The control module serves as the control center of the screw fastening device 1 , and the control module may include, but is not limited to, an MCU (Microcontroller Unit). The control module may be, but is not limited to, electrically connected to the detection component 22 via a wire.

[0060] The warning module serves as an alarm mechanism for the screw fastening device 1. The warning module is used to issue a warning prompt, which allows the operator to promptly remove the assembly component 2 with burrs 2b from the fixture 21. The warning prompt can be, but is not limited to, a voice prompt, a light prompt, a text prompt, etc. It can be understood that, for warning prompts in different forms, the specific forms of expression of the corresponding warning modules are also different; for example, when the warning prompt is a voice prompt, the warning module may but is not limited to including a buzzer, and when the detection component 22 detects that there is a burr 2b at the water outlet 2a of the part to be assembled 2, a warning signal is generated, and the control module controls the buzzer to sound according to the warning signal; for another example, when the warning prompt is a light prompt, the warning module may but is not limited to including an indicator light, and when the detection component 22 detects that there is a burr 2b at the water outlet 2a of the part to be assembled 2, a warning signal is generated, and the control module controls the indicator light to flash according to the warning signal; for another example, when the warning prompt is a text prompt, the warning module may but is not limited to including a display, and when the detection component 22 detects that there is a burr 2b at the water outlet 2a of the part to be assembled 2, a warning signal is generated, and the control module controls the display to display a warning slogan such as "Attention, unqualified" according to the warning signal.

[0061] The warning module can be installed on the rack 10, in which case the warning module can be but is not limited to being electrically connected to the control module via wires; the warning module can also be used alone, in which case the warning module can be but is not limited to being connected to the control module via Bluetooth communication.

[0062] By designing a control module and an early warning module, when the detection component 22 detects the presence of a burr 2b at the water outlet 2a of the part to be assembled 2, an early warning signal is generated. The control module controls the early warning module to issue an early warning prompt based on the early warning signal. The operator can then promptly remove the part to be assembled 2 with the burr 2b carried on the jig 21 according to the early warning prompt, and perform manual or mechanical automatic deburring 2b on the removed part to be assembled 2, and then replace the part to be assembled 2 with the burr 2b removed in the jig 21. This can effectively improve the accuracy of subsequent screw locking, and at the same time effectively reduce or even avoid the possibility of the burr 2b scratching the fabric in subsequent processes, thereby effectively improving the product yield.

[0063] like Figure 5-Figure 8As shown, the jig 21 includes a jig body 211 and a first positioning assembly 212; the jig body 211 is used to carry the part to be assembled 2 and is connected to the conveying module 30; the first positioning assembly 212 is installed on the jig body 211 and is used to fix the part to be assembled 2 carried by the jig body 211 to the jig body 211. The detection assembly 22 includes a first sensor 221; the first sensor 221 is disposed on the jig body 211 and is electrically connected to the control module. The first sensor 221 is used to detect whether there is a burr 2b at the sprue 2a of the part to be assembled 2 after the first positioning assembly 212 fixes the part to be assembled 2 to the jig body 211.

[0064] Among them, the fixture body 211 serves as a carrier of the fixture 21 for carrying the part to be assembled 2; the specific structure of the fixture body 211 is not limited here, and designers can make reasonable designs according to actual needs; for example, the fixture body 211 can be but is not limited to a plate structure or a frame structure.

[0065] The first positioning component 212, as a fixing component of the jig 21, is used to fix the part to be assembled 2 to the jig body 211, so as to achieve relative fixation of the position between the part to be assembled 2 and the jig body 211. The specific structure of the first positioning component 212 is not limited here, and designers can reasonably design it according to actual needs; for example, when the first positioning component 212 manually fixes the part to be assembled 2 to the jig body 211, the first positioning component 212 can, but is not limited to, include a pressure block provided on the jig body 211, and the operator manually adjusts the pressure block so that the pressure block is pressed against the part to be assembled 2, thereby achieving relative fixation of the position between the part to be assembled 2 and the jig body 211.

[0066] The first sensor 221 can be but is not limited to a pressure sensor. In this case, the pressure can be detected to determine whether there is a burr 2b at the sprue 2a of the part to be assembled 2; if the pressure value detected by the first sensor 221 is zero or small (caused by the processing error of the part to be assembled 2), it means that there is no burr 2b at the sprue 2a of the part to be assembled 2; conversely, if the pressure value detected by the first sensor 221 is large, it means that there is a burr 2b at the sprue 2a of the part to be assembled 2. For another example, the first sensor 221 may also be but is not limited to being a distance sensor. In this case, it can be determined whether there is a burr 2b at the sprue 2a of the part to be assembled 2 by sensing the distance between the sprue 2a of the part to be assembled 2 and the first sensor 221; if the first sensor 221 senses that the distance between the sprue 2a of the part to be assembled 2 and the first sensor 221 is zero or relatively close (caused by the processing error of the part to be assembled 2), it indicates that there is a burr 2b at the sprue 2a of the part to be assembled 2; conversely, if the first sensor 221 senses that the distance between the sprue 2a of the part to be assembled 2 and the first sensor 221 is relatively far, it indicates that there is no burr 2b at the sprue 2a of the part to be assembled 2.

[0067] The specific connection method between the first sensor 221 and the fixture body 211 is not limited here, and designers can make reasonable designs according to actual needs; for example, the first sensor 221 can be, but is not limited to, detachably connected to the fixture body 211 by at least one of screw connection, clip connection, or plug-in connection; for another example, the first sensor 221 can also be, but is not limited to, non-detachably connected to the fixture body 211 by gluing.

[0068] By designing the first sensor 221, the first sensor 221 is used to detect whether there is a burr 2b at the water outlet 2a of the part to be assembled 2 after the first positioning component 212 fixes the part to be assembled 2 to the jig body 211; if the first sensor 221 detects that there is a burr 2b at the water outlet 2a of the part to be assembled 2, the above-mentioned warning signal is generated, and the control module controls the warning module to make a warning prompt according to the warning signal. At this time, the operator can remove the part to be assembled 2 with the burr 2b carried on the jig body 211 in time according to the warning prompt, and perform manual or mechanical automatic deburring 2b on the removed part to be assembled 2, and then replace the part to be assembled 2 with the burr 2b removed into the jig body 211. This can effectively reduce or even avoid the possibility of inaccurate positioning of the part to be assembled 2 due to the burr 2b, thereby affecting the subsequent screw locking process, and reduce or even avoid the possibility of the burr 2b scratching the fabric in the subsequent process, thereby effectively improving the product yield.

[0069] Specifically, the jig 21 also includes a support 215, which is fixedly connected to the jig body 211 by means of screws. The support 215 has an inclined abutment surface 215a, which is provided with a mounting hole 215b. The first sensor 221 is disposed within the mounting hole 215b (and the sensing surface of the first sensor 221 is parallel to or coplanar with the abutment surface 215a). When the component 2 to be assembled is supported and fixed to the jig body 211, the plane of the nozzle 2a of the component 2 to be assembled abuts the abutment surface 215a.

[0070] like Figure 5-Figure 6 As shown, the first positioning assembly 212 includes a first driving member 2121 and a first positioning member 2122. The first driving member 2121 is mounted on the fixture body 211, and the first positioning member 2122 is mounted on the driving end of the first driving member 2121. The driving end of the first driving member 2121 can move in a second direction PP' to drive the first positioning member 2122 to move in the second direction PP' until it contacts the part to be assembled 2, thereby fixing the part to be assembled 2 to the fixture body 211. The second direction PP' intersects with the first direction OO'.

[0071] The first drive member 2121 serves as the power source for the first positioning assembly 212, driving the first positioning member 2122 to move in the second direction PP'. The specific form of the first drive member 2121 is not limited here, and designers can reasonably design it according to actual needs. For example, the first drive member 2121 can include a cylinder or a linear motor. The specific connection method between the first drive member 2121 and the fixture body 211 is not limited here, and designers can reasonably design it according to actual needs. For example, the first drive member 2121 can be, but is not limited to, fixedly connected to the fixture body 211 by screws.

[0072] The first positioning member 2122 is used as a fixing member of the first positioning assembly 212 to fix the assembly part 2 to the fixture body 211; the first positioning member 2122 can be, but is not limited to, a positioning pressure rod or a positioning pressure block. The specific connection method between the first positioning member 2122 and the driving end of the first driving member 2121 is not limited here, and designers can make reasonable designs according to actual needs; for example, when the first driving member 2121 includes a cylinder, the telescopic rod of the cylinder is connected to the first positioning member 2122 as the driving end, and the first positioning member 2122 can be, but is not limited to, being fixedly connected to the telescopic rod of the cylinder by at least one of screw connection, snap connection, or plug-in connection; for another example, when the first driving member 2121 includes a linear motor, the mover of the linear motor is connected to the first positioning member 2122 as the driving end, and the first positioning member 2122 can be, but is not limited to, being fixedly connected to the mover of the linear motor by at least one of screw connection, snap connection, or plug-in connection.

[0073] When the fixture body 211 is in the above-mentioned preset loading position, the driving end of the first driving member 2121 drives the first positioning member 2122 to move along the second direction PP' toward the part to be assembled 2 until it is close to the part to be assembled 2, so that the part to be assembled 2 is fixed to the fixture body. Then the first sensor 221 can detect whether there is a burr 2b at the water outlet 2a of the part to be assembled 2. If there is, the first sensor 221 generates an early warning signal, and the control module controls the early warning module to issue an early warning prompt according to the early warning signal. The driving end of the first driving member 2121 drives the first positioning member 2122 along the second direction PP' back to the part to be assembled 2 Move until it is separated from the part to be assembled 2. At this time, the operator can take out the part to be assembled 2 with burrs 2b carried on the fixture body 211, and manually or automatically remove the burrs 2b on the removed part to be assembled 2. Then, the part to be assembled 2 with the burrs 2b removed is placed back into the fixture body 211. The driving end of the first driving member 2121 drives the first positioning member 2122 to move along the second direction PP' toward the part to be assembled 2 until it is tightly pressed against the part to be assembled 2, so that the part to be assembled 2 is re-fixed on the fixture body, so that the subsequent locking module 40 can perform a locking operation on the part to be assembled 2.

[0074] like Figure 4-Figure 5 As shown, the detection assembly 22 further includes a second sensor 222; the second sensor 222 is disposed on the jig body 211 and electrically connected to the control module. The second sensor 222 is used to detect whether the part 2 to be assembled is resting on the jig body 211. The second sensor 222 generates a positioning signal when the second sensor 222 detects that the part 2 to be assembled is resting on the jig body 211. The control module is electrically connected to the first driving member 2121 and is further configured to control the driving end of the first driving member 2121 to move in the second direction PP' based on the positioning signal.

[0075] Among them, the second sensor 222 can be but is not limited to a color sensor. In this case, it can be determined whether the jig body 211 supports the part 2 to be assembled by detecting the color in the jig body 211; for example, the second sensor 222 can also be but is not limited to a distance sensor. In this case, it can be determined whether the jig body 211 supports the part 2 to be assembled by sensing the distance between the position for placing the part 2 to be assembled in the jig body 211 and the distance sensor.

[0076] The specific connection method between the second sensor 222 and the jig body 211 is not limited here, and designers can make reasonable designs based on actual needs; for example, the second sensor 222 can be, but is not limited to, detachably connected to the jig body 211 by at least one of screw connection, snap connection, or plug-in connection; for another example, the second sensor 222 can also be, but is not limited to, non-detachably connected to the jig body 211 by gluing. In the embodiment of the present application, the number of second sensors 222 is two; one second sensor 222 is used to detect whether the head of the part to be assembled 2 is resting on the jig body 211, and the other second sensor 222 is used to detect whether the tail of the part to be assembled 2 is resting on the jig body 211. When and only when both sensors generate the above-mentioned positioning signal, it can be determined that the part to be assembled 2 as a whole is resting on the jig body 211, which can effectively improve the detection accuracy of the second sensor 222.

[0077] By designing the second sensor 222, when the part to be assembled 2 is supported on the jig body 211, the second sensor 222 generates a positioning signal. The control module controls the driving end of the first driving member 2121 to move along the second direction PP' according to the positioning signal, so as to drive the first positioning member 2122 to move along the second direction PP' toward the part to be assembled 2 until it is pressed against the part to be assembled 2, thereby achieving relative fixation of the position between the part to be assembled 2 and the jig body 211.

[0078] Specifically, the first driving member 2121 includes a first cylinder, and the first positioning member 2122 includes a positioning rod; the telescopic rod of the first cylinder is connected to the positioning rod as the driving end of the first driving member 2121, and the telescopic rod of the first cylinder performs telescopic movement along the second direction PP' to drive the positioning rod to move along the second direction PP' toward the part to be assembled 2 until it is pressed against the part to be assembled 2, thereby achieving relative fixation of the position between the part to be assembled 2 and the fixture body 211.

[0079] like Figure 4-Figure 5 As shown, in order to enhance the stability of the part to be assembled 2 against the jig body 211 , other structural designs of the jig 21 may include, but are not limited to, one or more of the following embodiments.

[0080] In the first embodiment, the jig 21 further includes a second positioning assembly 213; the second positioning assembly 213 is mounted on the jig body 211 and is used to press the part 2 to be assembled, which is fixed to the jig body 211, along the first direction OO'. The second positioning assembly 213 is used to press the part 2 to be assembled, which is supported against the jig body 211, along the first direction OO', thereby achieving multi-directional fixation of the part 2 to be assembled, thereby effectively enhancing the stability of the part 2 to be assembled, which is supported against the jig body 211.

[0081] Specifically, the second positioning assembly 213 includes a second driving member 2131 and a second positioning member 2132. The second driving member 2131 is mounted on the fixture body 211. The second positioning member 2132 is mounted on the driving end of the second driving member 2131. The driving end of the second driving member 2131 can move in the first direction OO' to drive the second positioning member 2132 to move in the first direction OO' until it contacts the component 2 to be assembled.

[0082] The second drive member 2131 serves as the power source of the second positioning assembly 213, and is used to drive the second positioning member 2132 to move along the first direction OO'. The specific form of the second drive member 2131 is not limited here, and designers can reasonably design it according to actual needs. For example, the second drive member 2131 can include a cylinder or a linear motor. The specific connection method between the second drive member 2131 and the fixture body 211 is not limited here, and designers can reasonably design it according to actual needs. For example, the second drive member 2131 can be, but is not limited to, fixedly connected to the fixture body 211 by means of locking screws.

[0083] The second positioning member 2132 is used as an auxiliary positioning member of the second positioning assembly 213 to assist in cooperating with the first positioning member 2122 to more stably fix the assembly part 2 to be assembled to the fixture body 211; the second positioning member 2132 can be, but is not limited to, a positioning pressure plate or a positioning pressure block. The specific connection method between the second positioning member 2132 and the driving end of the second driving member 2131 is not limited here, and designers can make reasonable designs based on actual needs; for example, when the second driving member 2131 includes a cylinder, the telescopic rod of the cylinder is connected to the second positioning member 2132 as the driving end, and the second positioning member 2132 can be, but is not limited to, fixedly connected to the telescopic rod of the cylinder by at least one of screw connection, snap connection, or plug-in connection; for another example, when the second driving member 2131 includes a linear motor, the mover of the linear motor is connected to the second positioning member 2132 as the driving end, and the second positioning member 2132 can be, but is not limited to, fixedly connected to the mover of the linear motor by at least one of screw connection, snap connection, or plug-in connection.

[0084] When the jig body 211 is in the above-mentioned preset loading position, the driving end of the second driving member 2131 first drives the second positioning member 2132 to move along the first direction OO' toward the part to be assembled 2 until it is tightly pressed against the part to be assembled 2, and the driving end of the first driving member 2121 then drives the first positioning member 2122 to move along the second direction PP' toward the part to be assembled 2 until it is tightly pressed against the part to be assembled 2. In this way, the second positioning member 2132 cooperates with the first positioning member 2122 to realize multi-directional fixation of the part to be assembled 2, which can effectively enhance the connection stability between the part to be assembled 2 and the jig body 211.

[0085] More specifically, the second driving member 2131 includes a second cylinder, and the second positioning member 2132 includes a first positioning plate; the telescopic rod of the second cylinder serves as the driving end of the second driving member 2131 and is connected to the first positioning plate, and the telescopic rod of the second cylinder performs telescopic movement along the first direction OO' to drive the first positioning plate to move along the first direction OO' toward the part to be assembled 2 until it is pressed against the part to be assembled 2.

[0086] In the second embodiment, the jig 21 further includes a third positioning assembly 214 mounted on the jig body 211 and configured to press the part 2 to be assembled, which is secured to the jig body 211, along a third direction QQ' intersecting the first direction OO'. The third positioning assembly 214 is configured to press the part 2 to be assembled, which is supported against the jig body 211, along the third direction QQ', thereby achieving multi-directional fixation of the part 2 to be assembled, thereby effectively enhancing the stability of the part 2 to be assembled against the jig body 211.

[0087] Specifically, the third positioning assembly 214 includes a third driving member 2141 and a third positioning member 2142. The third driving member 2141 is mounted on the fixture body 211, and the third positioning member 2142 is mounted on the driving end of the third driving member 2141. The driving end of the third driving member 2141 can move along the third direction QQ' to drive the third positioning member 2142 along the third direction QQ' until it abuts against the assembly component 2. The third direction QQ', the second direction PP', and the first direction OO' intersect with each other.

[0088] The third drive member 2141 serves as the power source of the third positioning assembly 214, and is used to drive the third positioning member 2142 to move along the third direction QQ'. The specific form of the third drive member 2141 is not limited here, and designers can reasonably design it according to actual needs. For example, the third drive member 2141 can include a cylinder or a linear motor. The specific connection method between the third drive member 2141 and the fixture body 211 is not limited here, and designers can reasonably design it according to actual needs. For example, the third drive member 2141 can be, but is not limited to, fixedly connected to the fixture body 211 by screws.

[0089] The third positioning member 2142 is used as an auxiliary positioning member of the third positioning assembly 214 to assist in cooperating with the first positioning member 2122 to more stably fix the assembly 2 to be assembled to the fixture body 211; the third positioning member 2142 can be, but is not limited to, a positioning pressure plate or a positioning pressure block. The specific connection method between the third positioning member 2142 and the driving end of the third driving member 2141 is not limited here, and designers can make reasonable designs based on actual needs; for example, when the third driving member 2141 includes a cylinder, the telescopic rod of the cylinder is connected to the third positioning member 2142 as the driving end, and the third positioning member 2142 can be, but is not limited to, fixedly connected to the telescopic rod of the cylinder by at least one of screw connection, snap connection, or plug-in connection; for another example, when the third driving member 2141 includes a linear motor, the mover of the linear motor is connected to the third positioning member 2142 as the driving end, and the third positioning member 2142 can be, but is not limited to, fixedly connected to the mover of the linear motor by at least one of screw connection, snap connection, or plug-in connection.

[0090] When the jig body 211 is in the above-mentioned preset loading position, the driving end of the third driving member 2141 first drives the third positioning member 2142 to move along the third direction QQ' toward the part to be assembled 2 until it is tightly pressed against the part to be assembled 2, and the driving end of the first driving member 2121 then drives the first positioning member 2122 to move along the second direction PP' toward the part to be assembled 2 until it is tightly pressed against the part to be assembled 2. In this way, the third positioning member 2142 cooperates with the first positioning member 2122 to realize multi-directional fixation of the part to be assembled 2, which can effectively enhance the connection stability between the part to be assembled 2 and the jig body 211.

[0091] More specifically, the third driving member 2141 includes a third cylinder, and the third positioning member 2142 includes a second positioning plate; the telescopic rod of the third cylinder serves as the driving end of the third driving member 2141 and is connected to the second positioning plate, and the telescopic rod of the third cylinder performs telescopic movement along the third direction QQ' to drive the second positioning plate to move along the third direction QQ' toward the component to be assembled 2 until it is pressed against the component to be assembled 2.

[0092] It should be noted that the above-mentioned second driving member 2131 and the third driving member 2141 can be electrically connected to the above-mentioned control module. At this time, when the second sensor 222 detects that the part to be assembled 2 is supported on the fixture body 211 and generates the above-mentioned positioning signal, the control module first controls the driving end of the second driving member 2131 to move along the first direction OO' and the driving end of the third driving member 2141 to move along the third direction QQ' according to the positioning signal, and then controls the driving end of the first driving member 2121 to move along the second direction PP'.

[0104] The working principle of the screw fastening device 1 is described below, specifically:

[0105] Step 1: The fixture body 211 is at a preset loading position. The operator places the component 2 to be assembled on the fixture body 211 and triggers the start button.

[0106] Step 2: The second sensor 222 detects that the part to be assembled 2 generates a positioning signal. The control module controls the telescopic rod of the second cylinder to extend along the first direction OO' according to the positioning signal, thereby driving the first positioning plate to move along the first direction OO' toward the part to be assembled 2 until it is pressed against the part to be assembled 2. The control module also controls the telescopic rod of the third cylinder to extend along the third direction QQ', thereby driving the second positioning plate to move along the third direction QQ' toward the part to be assembled 2 until it is pressed against the part to be assembled 2. The control module also controls the telescopic rod of the first cylinder to extend along the second direction PP', thereby driving the positioning rod to move along the second direction PP' toward the part to be assembled 2 until it is pressed against the part to be assembled 2, thereby fixing the part to be assembled 2 to the fixture body 211.

[0107] Step 3: If the first sensor 221 does not detect the presence of the burr 2b at the nozzle 2a of the component 2 to be assembled, the control module controls the second linear motor to move the jig body 211 to the preset assembly position;

[0108] Step 4: The telescopic rod of the fourth cylinder extends along the third direction QQ' to move the dividing part 412 to the preset assembly position directly below the batch nozzle 422; the telescopic rod of the fifth cylinder moves downward along the second direction PP' to make the batch nozzle 422 contact the screw in the dividing trough, and the vacuum is turned on. The screw is adsorbed to the batch nozzle 422 under the action of the suction force; the telescopic rod of the fourth cylinder retracts along the third direction QQ', disengages from the position directly below the batch nozzle 422, and moves back to the position where the dividing trough is aligned with the discharge port of the feeding pipe of the feeder 411; the vacuum is turned off, the lifting cylinder 434 lowers the batch rod 433 and extends it from the batch nozzle 422, and the locking motor 431 is turned on to drive the batch rod 433 to rotate. The batch rod 433 rotates to lock the screw in the hole of the part to be assembled 2 to assemble to form an assembly;

[0109] Step 5: The control module controls the second linear motor to move the fixture body 211 to a preset unloading position;

[0110] Step 6: The telescopic rod of the sixth cylinder extends downward along the second direction PP' until the grippers 522 are located on both sides of the assembly; the clamping cylinder 521 extends along the third direction QQ' until the grippers 522 clamp the assembly; the telescopic rod of the sixth cylinder contracts upward along the second direction PP' until the assembly is separated from the fixture body 211; the mover of the first linear motor moves along the first direction OO' to move the assembly to the top of the finished product collection frame; the clamping cylinder 521 contracts along the third direction QQ' until the grippers 522 release the assembly, and the assembly successfully falls into the finished product collection frame; the mover of the first linear motor moves along the first direction OO' to move the grippers 522 back to the top of the preset unloading position.

[0111] It should be noted that after the telescopic rod of the sixth cylinder drives the assembly to separate from the jig body 211, the control module controls the second linear motor to move the jig body 211 back to the preset loading position. At this time, the operator can place the new part 2 to be assembled on the jig body 211, and repeat the operation to achieve mass production.

[0112] In addition, after step 2 above, it also includes:

[0113] Step 7: If the first sensor 221 detects that there is a burr 2b at the water outlet 2a of the component to be assembled 2, the first sensor 221 generates an early warning signal, and the control module controls the early warning module to make an early warning prompt according to the early warning signal, and the equipment is in a pause state; the control module controls the telescopic rod of the second cylinder to retract along the first direction OO' to drive the first positioning plate to move along the first direction OO' back to the component to be assembled 2 until it is separated from the component to be assembled 2, and also controls the telescopic rod of the third cylinder to retract along the third direction QQ' to drive the second positioning plate to move along the third direction QQ' back to the component to be assembled 2 Move until it is separated from the part to be assembled 2, and control the telescopic rod of the first cylinder to perform a contraction movement along the second direction PP', so as to drive the positioning rod to move along the second direction PP' back to the part to be assembled 2 until it is separated from the part to be assembled 2; at this time, the operator can remove the part to be assembled 2 with burrs 2b carried on the jig body 211, and perform manual or mechanical automatic deburring 2b on the removed part to be assembled 2, and then replace the part to be assembled 2 with the burrs 2b removed in the jig body 211, and the operator presses the recovery button, and the equipment jumps to re-execute the above step 2.
