[0007] By adopting the above technical solution, the first driving mechanism can drive the detection parts to approach each other along the second direction, so as to clamp the hoop placed on the detection table.

[0011] By adopting the above technical solution, the two connecting plates threadedly connected to the active bidirectional lead screw can be made to approach and move away from each other at the same time by utilizing the rotation of the bidirectional lead screw. The rotation of the bidirectional lead screw is controlled by the reciprocating movement of the first pusher, so that the amount of rotation of the bidirectional lead screw can be the same each time, so that the movement distance of the two connecting plates is the same in each cycle.

[0015] By adopting the above technical solution, using the transmission rod to transmit power to the driven bidirectional lead screw can enable the driven bidirectional lead screw to assist the active bidirectional lead screw in driving the connecting plates to move closer to or further away from each other, thereby balancing the force so that the force applied to the connecting plates can be located at the center of the connecting plates, making the connecting plates more stable in the process of moving closer to or further away from each other.

[0017] By adopting the above technical solution and utilizing the differential operation of the second pusher, the angle of the detection member can be changed.

Then the push plate slides along the material transport platform. After the push plate leaves the storage bin below in the vertical direction, the ring hoop falls to the top of the material transport platform under the action of gravity. Then the push plate slides in the opposite direction, pushes the ring hoop to the feed pipe, and is guided to the testing platform by the feed pipe. At this time, the next ring hoop to be tested falls to the top of the push plate under the action of gravity, waiting to be sent to the feed pipe by the push plate.

DETAILED DESCRIPTION

[0027] In this application, unless otherwise stated, directional words such as "inside" and "outside" refer to the contours of the corresponding components themselves, and directional words such as "first direction" refer to the Figure 1 The x direction is the direction of Figure 1 The y direction.

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] The embodiment of the present application discloses a hoop force value detection device.

[0030] like Figure 1 As shown, the hoop force value detection device includes a workbench 1, a screening device 2 and a feeding device 3. The workbench 1 has a work surface 105, and a waste material recovery port 101 and a finished material recovery port 103 are arranged on the work surface 105 of the workbench 1 along the first direction. A waste material recovery box 102 and a finished material recovery box 104 are arranged under the workbench 1, wherein the waste material recovery box 102 is arranged below the waste material recovery port 101 along the vertical direction, and the finished material recovery box 104 is arranged below the finished material recovery port 103 along the vertical direction. The screening device 2 is arranged at a position between the waste material recovery port 101 and the finished material recovery port 103 on the workbench 1, and the feeding device 3 is used to deliver the hoop to the screening device 2.

[0031] like Figure 1 As shown, the screening device 2 includes a first driving mechanism 201, a second driving mechanism 202, a detection platform 203 and two detection members 204. The detection platform 203 is arranged on the working surface 105 for placing the ring hoop to be tested, and two detection members 204 extending along the first direction are arranged at intervals along the second direction. A pressure sensor 205 is provided on the side where the two detection members 204 are close to each other, and the first driving mechanism 201 is used to drive the two detection members 204 to approach or move away from each other along the second direction. When the two detection members 204 are close to each other, the pressure sensor 205 on the detection member 204 can contact the ring hoop to be tested placed on the detection platform 203. As the two detection members 204 continue to approach, until the first driving mechanism 201 can drive the two detection members 204 to approach each other, the two detection members 204 can clamp the ring hoop to be tested and deform it. The pressure sensor 205 is used to detect the force value of the ring hoop at this time. In order to facilitate the staff to read the readings, a display can be provided on one side of the workbench 1, and the pressure sensor 205 can be connected to the display signal and display the readings on the display.

[0032] The staff can judge by the reading whether the clamped hoop is qualified at this time. If the hoop is qualified, the staff can use the second driving mechanism 202 to change the angle between the two detection parts 204, so that the hoop is ejected to the finished material recovery port 103 along the positive direction of the first direction, and falls into the finished material recovery box 104 under the action of gravity. If the hoop is unqualified, the staff can use the second driving mechanism 202 to reversely change the angle between the two detection parts 204, so that the hoop is ejected to the waste material recovery port 101 along the negative direction of the first direction, and falls into the waste material recovery box 102 under the action of gravity.

[0033] like Figure 1 and Figure 2 As shown, the first driving mechanism 201 includes a first pusher 2011, an active bidirectional lead screw 2012 and a connecting plate 2013. The active bidirectional lead screw 2012 is arranged along the second direction, the number of connecting plates 2013 is two, the connecting plates 2013 are respectively arranged on both sides of the detection platform 203 and are respectively threadedly connected with two opposite thread segments of the active bidirectional lead screw 2012, the first pusher 2011 is arranged above the working surface 105 of the workbench 1, and the fixed end of the first pusher 2011 is fixedly connected with the workbench 1, the output end of the first pusher 2011 is provided with a connecting block 2014, the bottom of the connecting block 2014 is provided with a rack 2015, and the thread segment of the active bidirectional lead screw 2012 is provided with a gear 2016 matched with the rack 2015 at the place where the rotation direction of the thread segment of the active bidirectional lead screw 2012 changes.

[0034] When the active bidirectional lead screw 2012 rotates around its own axis, the two connecting plates 2013 can simultaneously approach or move away from each other under the effect of two threads with opposite rotation directions. By controlling the leads of the two opposite thread segments of the active bidirectional lead screw 2012 to be the same, the two connecting plates 2013 can be guaranteed to have the same displacement speed.

[0035] like Figure 1 and Figure 2 As shown, in order to ensure that the two connecting plates 2013 can stably approach or move away from each other along the second direction, rather than being pushed along the first direction under the action of the gear 2016 and the rack 2015, the screening device 2 further includes a guide mechanism. The guide mechanism includes a slide rail 20112 and a slider 20113, the slide rail 20112 is arranged on the working surface 105 along the second direction and passes through the detection platform 203, the number of the sliders 20113 is two, the sliders 20113 are respectively arranged on both sides of the detection platform 203 and are slidably connected to the slide rail 20112, and the connecting plates 2013 are respectively fixedly connected to the tops of the sliders 20113.

[0036] like Figure 1 and Figure 2As shown, in order to balance the force on the connecting plate 2013, the first driving mechanism 201 further includes a bracket 2018, a driven bidirectional lead screw 2017 and a transmission rod 2019. There are two brackets 2018, the two brackets 2018 extend along the second direction, and are spaced apart on the working surface 105 along the first direction. The two brackets 2018 are respectively located on the side of the finished material recovery port 103 away from the detection table 203 and the side of the waste material recovery port 101 away from the detection table 203. The transmission rod 2019 is arranged along the first direction and is connected to the bracket 2018 so as to be rotatable around its own axis. The driven bidirectional lead screw 2017 is arranged along the second direction. Two opposite thread segments of the driven bidirectional lead screw 2017 are respectively threadedly connected to one end of the connecting plate 2013 away from the active bidirectional lead screw 2012. The transmission rod 2019 is transmission-connected to the active bidirectional lead screw 2012 through the first bevel gear 2016 assembly, and the driven bidirectional lead screw 2017 is transmission-connected to the transmission rod 2019 through the second bevel gear 2016 assembly. The number of the transmission rods 2019 can be one or more. In the present embodiment, the number of the transmission rods 2019 is two, and the two transmission rods 2019 are located in the same horizontal plane and are respectively arranged on both sides of the detection platform 203 along the first direction.

[0037] In actual operation, when the active bidirectional lead screw 2012 rotates around its own axis, the transmission rod 2019 can rotate around its own axis together with the active bidirectional lead screw 2012 under the action of the first bevel gear 2016 assembly, so that the driven bidirectional lead screw 2017 can rotate around its own axis together with the transmission rod 2019 under the action of the second bevel gear 2016 assembly. When the driven bidirectional lead screw 2017 rotates around its own axis, the two connecting plates 2013 can simultaneously approach or move away from each other under the action of two threads with opposite rotation directions. By controlling the leads of the two opposite thread segments of the driven bidirectional lead screw 2017 to be the same, and the leads of the two opposite thread segments of the active bidirectional lead screw 2012 to be the same, it can be ensured that the two connecting plates 2013 have the same displacement speed.

[0038] Therefore, through the transmission of the transmission rod 2019, power can be transmitted from the active bidirectional lead screw 2012 to the driven bidirectional lead screw 2017, so that the driven bidirectional lead screw 2017 assists the active bidirectional lead screw 2012 to drive the connecting plates 2013 to move closer or farther away from each other. It plays a balancing role, so that the force applied to the connecting plate 2013 can be located at the central position of the connecting plate 2013, making the connecting plate 2013 more stable in the process of moving closer or farther away from each other.

[0039] like Figure 1 and Figure 2As shown, the second driving mechanism 202 includes two steering drive components, which are respectively arranged on the connecting plate 2013 and drivingly connected to the detection member 204. The steering drive component includes two second pushers 2021 spaced apart along the second direction, the fixed end of the second pusher 2021 is fixedly connected to the connecting plate 2013, and the output end of the second pusher 2021 is hingedly connected to the detection member 204. The first pusher 2011 and the second pusher 2021 can be cylinders, hydraulic cylinders or electric push rods. Considering the load, in this embodiment, the first pusher 2011 and the second pusher 2021 are both cylinders.

[0040] In actual use, the first driving mechanism 201 is first used to drive the two detection members 204 to approach each other until the hoop to be tested is clamped, and the force value of the hoop at this time is detected. According to the value, the second pusher 2021 in the steering drive assembly is differentially operated to change the angle of the detection member 204. For example, when the force value of the hoop is detected to be unqualified, the two second pushers 2021 on the side close to the waste recovery port 101 in the two steering drive assemblies are contracted, and the two second pushers 2021 on the side away from the waste recovery port 101 are extended, and the angle between the two detection members 204 is changed under the action of the second driving mechanism 202, so that the hoop is launched to the waste recovery port 101. Similarly, when the force value of the hoop is detected to be qualified, the two second pushing members 2021 on the side close to the material recovery port 103 in the two steering drive components are contracted, and the two second pushing members 2021 on the side away from the material recovery port 103 are extended, and the angle between the two detection members 204 is changed under the action of the second drive mechanism 202, thereby launching the hoop to the material recovery port 103.

[0041] In order to make the launching process of the hoop smoother and avoid the hoop being stuck between two detection members 204, protrusions 206 can be provided on both sides of the pressure sensor 205 on the detection member 204. When the angle of the detection member 204 changes, the protrusion 206 contacts the hoop and pushes the hoop out from between the two detection members 204, thereby utilizing the elasticity of the hoop itself to launch the hoop from the detection platform 203.

[0042] like Figure 1 and Figure 3 As shown, in order to enable the hoop to accurately fall into the waste recovery port 101 or the finished material recovery port 103, the two brackets 2018 can be set close to the waste recovery port 101 or the finished material recovery port 103, and at the same time, a soft pad 207, such as a sponge pad, a cotton pad or an air cushion, is set on the side where the two brackets 2018 are close to each other, so that the launched hoop collides with the soft pad 207 and thus falls into the waste recovery port 101 or the finished material recovery port 103.

[0043] In order to realize automatic control, the screening device 2 may further include a control mechanism, which is respectively connected to the pressure sensor 205, the first drive mechanism 201 and the second drive mechanism 202 by signal. The control mechanism can read the value detected by the pressure sensor 205 after the first drive mechanism 201 clamps the hoop, compare the value with the preset value in the control mechanism, and control the second drive mechanism 202 to launch the hoop with qualified force value from the detection table 203 to the finished material recovery port 103 and launch the hoop with unqualified force value from the detection table 203 to the waste material recovery port 101 according to the comparison result.

[0044] like Figure 1 and Figure 2 As shown, the loading device 3 includes a feeding pipe 301, a pushing plate 302, a transport platform 303 and a storage bin 304. The transport platform 303 is fixedly connected to the workbench 1. The feeding pipe 301 is arranged above the inspection platform 203 in the vertical direction and passes through the transport platform 303. The top of the feeding pipe 301 is kept horizontal with the transport platform 303. The storage bin 304 is arranged above the transport platform 303 and is located on the side of the feeding pipe 301 close to the pushing member. The storage bin 304 is arranged in the vertical direction and is fixedly connected to the transport platform 303 through a support frame 305. The pushing plate 302 is slidably connected to the transport platform 303 and is fixedly connected to the connecting block 2014 to push the hoop at the storage bin 304 to the feeding pipe 301.

[0045] The storage bin 304 is used to store the hoop to be tested. The storage bin 304 is set to match the shape of the hoop, so that the hoop can reach the discharge port of the storage bin 304 from the feed port of the storage bin 304 along its own axis under the action of gravity, and fall to the top of the push plate 302. By controlling the distance between the discharge port of the storage bin 304 and the top of the push plate 302 and the thickness of the push plate 302, it can be ensured that the hoop will not leave the storage bin 304 when it contacts the top of the push plate 302. Subsequently, the first pusher 2011 is used to pull back the connecting block 2014, thereby driving the push plate 302 to slide along the material transport platform 303. When the push plate 302 leaves the storage bin 304 below the vertical direction, the hoop falls to the top of the material transport platform 303 under the action of gravity. Subsequently, the first pusher 2011 pushes the connecting block 2014, and the push plate 302 slides in the opposite direction, pushing the hoop to the feeding pipe 301, and the feeding pipe 301 guides the hoop to the testing platform 203. At this time, the next hoop 4 to be tested will fall to the top of the push plate 302 under the action of gravity, waiting to be sent to the feeding pipe 301 by the push plate 302.

[0046] At the same time, since the rack 2015 is fixedly connected to the bottom of the connecting block 2014, when the first pushing member 2011 pushes the connecting block 2014, the rack 2015 drives the active bidirectional lead screw 2012 to rotate around its own axis, and the active bidirectional lead screw 2012 drives the driven bidirectional lead screw 2017 to rotate around its own axis under the action of the first bevel gear 2016 assembly, the second bevel gear 2016 assembly and the transmission rod 2019, and the active bidirectional lead screw 2012 and the driven bidirectional lead screw 2017 simultaneously drive the two detection members 204 away from each other until the limit distance that the first driving mechanism 201 can drive the two detection members 204 away from each other is reached, and the hoop is sent to the feeding pipe 301 and guided to the detection table 203 by the feeding pipe 301. Similarly, when the first pushing member 2011 pulls back the connecting block 2014, the active bidirectional lead screw 2012 and the driven bidirectional lead screw 2017 simultaneously drive the two detection members 204 to approach each other until the limit distance at which the first driving mechanism 201 can drive the two detection members 204 to approach each other is reached. The two detection members 204 clamp the ring hoop to be tested and cause it to deform. The pressure sensor 205 detects the force value of the ring hoop at this time and feeds the value back to the control mechanism. The control mechanism controls the second driving component according to the value to launch the ring hoop from the detection platform 203 to the waste recovery port 101 or the finished material recovery port 103. At the same time, the next ring hoop 4 to be tested in the storage bin 304 falls to the top of the material transport platform 303 under the action of gravity, waiting to be sent to the feeding pipe 301 by the pushing plate 302.

[0047] like Figure 1 and Figure 2 As shown, in order to limit the ring hoop from displacement other than along the first direction during the process of being pushed by the pushing plate 302, a limit member 306 is provided on the side of the pushing plate 302 away from the first pushing member 2011, and the contour of the limit member 306 matches the contour of the ring hoop, so that the outer wall of the ring hoop can abut against the limit member 306.

[0048] The implementation principle of a hoop force detection device in an embodiment of the present application is: before use, the first pushing member 2011 is controlled to extend to the extreme position. After the pushing member is extended to the extreme position, the hoop to be detected is placed in the storage bin 304. At this time, the hoop 4 to be detected closest to the bottom in the storage bin 304 falls from the storage bin 304 to the top of the push plate 302 under the action of gravity, and the top of the hoop still remains in the storage bin 304, and then the detection device is turned on.

[0049] After the detection device is turned on, the first pusher 2011 pulls back the connecting block 2014, thereby driving the push plate 302 to slide along the material transport platform 303. When the push plate 302 leaves the storage bin 304 and is vertically below, the hoop 4 to be detected in the storage bin 304, which is closest to the bottom, falls to the top of the material transport platform 303 under the action of gravity. Subsequently, the first pusher 2011 extends and pushes the connecting block 2014. The hoop is pushed to the feeding pipe 301 under the action of the push plate 302 and the stopper 306, and is guided to the detection platform 203 by the feeding pipe 301. At this time, the next hoop 4 to be detected falls from the storage bin 304 to the top of the push plate 302 under the action of gravity, waiting for the push plate 302 to leave so as to fall to the material transport platform 303 under the action of gravity. At the same time, since the rack 2015 is fixedly connected to the bottom of the connecting block 2014, when the first pushing member 2011 extends and pushes the connecting block 2014, the rack 2015 drives the active bidirectional lead screw 2012 to rotate around its own axis, and the active bidirectional lead screw 2012 drives the driven bidirectional lead screw 2017 to rotate around its own axis under the action of the first bevel gear 2016 assembly, the second bevel gear 2016 assembly and the transmission rod 2019. The active bidirectional lead screw 2012 and the driven bidirectional lead screw 2017 simultaneously drive the two detection members 204 away from each other until the first driving mechanism 201 reaches the limit distance that can drive the two detection members 204 away from each other, providing space for the hoop to fall for the detection table 203.

[0050] After the hoop is sent to the testing platform 203, the first pusher 2011 pulls back the connecting block 2014, thereby driving the push plate 302 to slide along the material transport platform 303. When the push plate 302 leaves the storage bin 304 below the vertical direction, the hoop falls to the top of the material transport platform 303 under the action of gravity, waiting to be sent to the feeding pipe 301 by the push plate 302. At the same time, the active bidirectional lead screw 2012 and the driven bidirectional lead screw 2017 simultaneously drive the two detection members 204 to approach each other, until the first driving mechanism 201 reaches the limit distance that the two detection members 204 can drive to approach each other, the two detection members 204 clamp the hoop to be tested and deform it, the pressure sensor 205 detects the force value of the hoop at this time, and feeds the value back to the control mechanism, and the control mechanism controls the second driving component to work according to the value.

[0051] When the force value of the hoop is detected to be unqualified, the two second pushers 2021 on the side close to the waste recovery port 101 in the two steering drive components are contracted, and the two second pushers 2021 on the side away from the waste recovery port 101 are extended, and the angle between the two detection members 204 is changed under the action of the second drive mechanism 202, so that the hoop is launched to the waste recovery port 101. Similarly, when the force value of the hoop is detected to be qualified, the two second pushers 2021 on the side close to the finished material recovery port 103 in the two steering drive components are contracted, and the two second pushers 2021 on the side away from the finished material recovery port 103 are extended, and the angle between the two detection members 204 is changed under the action of the second drive mechanism 202, so that the hoop is launched to the finished material recovery port 103.

[0052] After the hoop is launched from the detection table 203 to the waste recovery port 101 or the finished material recovery port 103, the pressure sensor 205 detects that there is no hoop at the detection table 203. At this time, the second driving mechanism 202 is controlled to reset and the first pushing member 2011 is controlled to extend, and then the above steps are repeated until all hoop detection is completed.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
