[0039] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] Reference below Figures 1-4 The following describes a landing detection device 100 according to an embodiment of the first aspect of the present invention.

[0041] like Figures 1-4 As shown, the landing detection device 100 according to the embodiment of the first aspect of the present utility model includes: a mounting bracket 10, a trigger member 20 and a detection switch 30.

[0042] Specifically, the trigger member 20 has a first end 21 and a second end 22 at both ends in the length direction, and a mounting portion 23 is provided on the trigger member 20, and the mounting portion 23 is located between the first end 21 and the second end 22. The trigger member 20 is rotatably connected to the mounting bracket 10 through the mounting portion 23, and the trigger member 20 is rotatable between the initial position and the trigger position. The trigger member 20 is configured so that the workpiece falls onto the first end 21 to drive the trigger member 20 to rotate from the initial position to the trigger position. When the trigger member 20 is in the trigger position, the detection switch 30 is triggered through the second end 22.

[0043] During the operation of the production system 1000, before the workpiece falls, the trigger member 20 is in the initial position. When the workpiece is positioned, the workpiece will fall onto the first end 21. Driven by the workpiece, the trigger member 20 will rotate on the mounting bracket 10, causing the trigger member 20 to rotate from the initial position to the trigger position. At the same time, the relative position of the second end 22 and the detection switch 30 changes, causing the detection switch 30 to be triggered, thereby causing the production system 1000 to determine that the workpiece is positioned, thereby realizing the detection of the position of the workpiece.

[0044] Among them, it can be understood that the detection switch 30 is triggered by rotating the trigger member 20, and the force acting on the rotation connection between the trigger member 20 and the mounting bracket 10 is relatively small. During use, the probability of failure of the landing detection device 100 can be reduced, thereby improving the reliability of the landing detection device 100 during operation. In addition, during the detection process, the position accuracy requirement for the workpiece when it falls on the first end 21 is relatively low, and the probability that the workpiece cannot drive the trigger member 20 to rotate is relatively low, which can further improve the reliability of the landing detection device 100 during operation.

[0045] According to the placement detection device 100 of the embodiment of the first aspect of the present invention, the placement detection of workpieces in the production system 1000 can be realized, and the reliability during the working process is high.

[0046] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, one of the mounting portion 23 and the mounting bracket 10 is provided with a shaft hole 231 and the other is provided with a rotating shaft 11 , and the rotating shaft 11 is rotatably fitted in the shaft hole 231 .

[0047] That is, the mounting portion 23 may be provided with an axial hole 231 , and the mounting bracket 10 may be provided with a rotating shaft 11 ; or the mounting portion 23 may be provided with a rotating shaft 11 , and the mounting bracket 10 may be provided with an axial hole 231 .

[0048] The rotational matching structure of the rotating shaft 11 and the shaft hole 231 is relatively simple, and the requirements for matching accuracy during the assembly process are relatively low, which can reduce the assembly difficulty and improve the assembly efficiency.

[0049] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, in the length direction of the trigger member 20, the trigger member 20 has a first portion 24 and a second portion 25 connected to opposite sides of the mounting portion 23. The first portion 24 is located on the side of the mounting portion 23 facing the detection switch 30. The trigger member 20 is configured to be suitable for driving the trigger member 20 to rotate from the trigger position to the initial position under the action of the gravity of the first portion 24.

[0050] The gravity of the first part 24 is G1, the distance between the center of gravity of the first part 24 and the rotation axis is R1, the gravity of the second part 25 is G2, the distance between the center of the second part 25 and the rotation axis is R2, G1*R1>G2*R2.

[0051] During the operation of the production system 1000, after the workpiece falls into place, the workpiece is removed from the first end 21. Under the action of the gravity of the first part 24, the trigger member 20 rotates from the trigger position to the initial position on the mounting bracket 10. Thus, the trigger member 20 can be reset, and the gravity of the first part 24 provides a reset driving force. The reset driving force has high reliability, which can further improve the reliability of the landing detection device 100 during operation, and can simplify the structure of the landing detection device 100, reducing the design difficulty of the landing detection device 100.

[0052] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the mounting portion 23 is formed in a circular plate shape, and the shaft hole 231 penetrates the mounting portion 23 along the thickness direction of the mounting portion 23 .

[0053] It can be understood that in order to ensure that the connection strength between the trigger member 20 and the mounting bracket 10 meets the requirements of use, the distance between the shaft hole 231 and the edge of the mounting portion 23 in the radial direction of the shaft hole 231 needs to be greater than a threshold. By forming the mounting portion 23 into a circular plate shape, it is easier to control the distance between the shaft hole 231 and the edge of the mounting portion 23 during the product design process. At the same time, the gravity of the mounting portion 23 is more evenly distributed around the axis of the shaft hole 231, which can reduce the difficulty of designing the gravity and center of gravity of the first part 24 and the second part 25, thereby reducing the difficulty of product design.

[0054] In some embodiments of the present invention, Figure 1-Figure 3 As shown, a deep groove ball bearing 232 is provided in the shaft hole 231, and the rotating shaft 11 is engaged with the shaft hole 231 through the deep groove ball bearing 232. The deep groove ball bearing 232 has a simple structure, which can reduce the difficulty of assembly. In addition, the deep groove ball bearing 232 has a strong ability to resist dust interference, which can further improve the reliability of the landing detection device 100 during operation.

[0055] Preferably, a limiting boss is formed on the outer peripheral wall of the rotating shaft 11, and the deep groove ball bearing 232 is sleeved on the rotating shaft 11. One side of the deep groove ball bearing 232 abuts against the limiting boss, and the other side of the deep groove ball bearing 232 abuts against the elastic retaining ring sleeved on the rotating shaft 11, thereby realizing the installation of the deep groove ball bearing 232 on the rotating shaft 11. Threaded holes are formed on the outer peripheral wall of the deep groove ball bearing 232 and the inner wall of the shaft hole 231, and the deep groove ball bearing 232 is installed in the shaft hole 231 by fastening screws.

[0056] In some embodiments of the present invention, Figure 1-Figure 3 As shown, a limiting portion 26 is formed on the trigger member 20, and a limiting member 12 is provided on the mounting bracket 10. When the trigger member 20 is in the initial position, the limiting portion 26 cooperates with the limiting member 12 in a limiting manner.

[0057] In the process of the trigger member 20 being driven by the gravity of the first part 24 to rotate from the trigger position to the initial position, when the trigger member 20 rotates to the initial position, the limit part 26 cooperates with the limit member 12 to prevent the trigger member 20 from continuing to rotate. In this way, the limit of the trigger member 20 during the resetting process can be achieved, so that the landing detection device 100 can work normally.

[0058] Preferably, the limiting member 12 is formed as a limiting block, and the limiting portion 26 is formed as a limiting protrusion.

[0059] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the position-limiting member 12 is provided with a first buffer member 121. The position-limiting member 12 is adapted to engage with the position-limiting portion 26 through the first buffer member 121. Thus, the first buffer member 121 can absorb a portion of the impact force between the position-limiting portion 26 and the position-limiting member 12, thereby reducing the probability of damage to the position-limiting member 12 and the position-limiting portion 26, and further improving the reliability of the position detection device 100 during operation. Preferably, the first buffer member 121 is a polyurethane buffer member.

[0060] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, a second buffer member 211 is provided on the upper side of the first end 21, and the trigger member 20 is adapted to contact the workpiece via the second buffer member 211. Thus, when the workpiece falls onto the first end 21, the second buffer member 211 can absorb a portion of the impact force between the workpiece and the first end 21, thereby reducing the probability of damage to the trigger member 20 and the workpiece, further improving the reliability of the landing detection device 100 during operation, and increasing the yield rate of the workpiece. Preferably, the second buffer member 211 is a polyurethane buffer member. In the initial position, the upper surface of the second buffer member 211 is parallel to the upper surface of the support platform 230.

[0061] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the mounting bracket 10 includes a first support member 13 and a second support member 14, which are arranged at intervals, and the rotating shaft 11 is rotatably mounted on the first support member 13 and the second support member 14, and the distance between the first support member 13 and the second support member 14 is adjustable.

[0062] Among them, by setting the first support member 13 and the second support member 14, the first support member 13 and the second support member 14 can provide support at both ends of the rotating shaft 11, thereby improving the stability of the rotating shaft 11, and the mounting bracket 10 is split into the first support member 13 and the second support member 14. During the design process of the production system 1000, the positions of the first support member 13, the second support member 14 and the conveyor belt 210 can be arranged according to the layout space requirements. For example, the first support member 13 and the second support member 14 can be lowered and respectively arranged on both sides of the conveyor belt 210. In this way, the layout space of the production system 1000 can be saved.

[0063] Since the distance between the first support member 13 and the second support member 14 is adjustable, the relative position of the installation point of the trigger member 20 on the rotating shaft 11 and the conveyor belt 210 can be adjusted during the design of the production system 1000, thereby reducing the design difficulty of the production system 1000.

[0064] In some embodiments of the present invention, Figure 1-Figure 3 As shown, a first hole is formed on the first support member 13, and a second hole is formed on the second support member 14. The mounting bracket 10 also includes: a first fastener 15, which passes through the first hole and the second hole in sequence to fix the first support member 13 and the second support member 14 together.

[0065] Thus, during the design process of production system 1000, after adjusting the spacing between first support member 13 and second support member 14, first fastener 15 of an appropriate length can be selected to securely connect first support member 13 and second support member 14. This simplifies the structure of mounting bracket 10, further reducing the design difficulty of production system 1000. Furthermore, by securely connecting first support member 13 and second support member 14, the stability of mounting bracket 10 can be improved, thereby further improving the stability of rotating shaft 11.

[0066] In some embodiments of the present invention, the detection switch 30 is a travel switch, a proximity switch, or a magnetic switch. During the design of the production system 1000, a suitable detection switch 30 can be selected according to the use requirements.

[0067] Among them, such as Figure 1As shown, when the detection switch 30 is a travel switch, the travel switch includes a switch body and a connecting rod 31. One end of the connecting rod 31 is connected to the switch body, and the other end of the connecting rod 31 is rotatably connected to the second end 22. When the trigger member 20 rotates from the initial position to the trigger position, the second end 22 drives the connecting rod 31 to rotate, so that the connecting rod 31 triggers the trigger device in the switch body, thereby realizing the triggering of the detection switch 30 by the trigger member 20, thereby realizing the detection of the position of the workpiece.

[0068] like Figure 2 As shown, when the detection switch 30 is a proximity switch, in the initial position, the second end 22 is close to the proximity switch, and the proximity switch is in the on state. When the trigger member 20 rotates from the initial position to the trigger position, the second end 22 is away from the proximity switch, and the proximity switch is in the off state. Thus, the trigger member 20 triggers the detection switch 30, thereby realizing the detection of the position of the workpiece.

[0069] like Figure 3 As shown, when the detection switch 30 is a magnetic switch, the second end 22 is provided with a magnetic member. In the initial position, the magnetic member is close to the magnetic switch and magnetically cooperates with it, and the magnetic switch is in the on state. When the trigger member 20 rotates from the initial position to the trigger position, the magnetic member is away from the magnetic switch, and the magnetic cooperation between the magnetic member and the magnetic switch is cancelled, so that the magnetic switch is in the off state. Thus, the trigger member 20 triggers the detection switch 30, thereby realizing the detection of the position of the workpiece.

[0070] In some embodiments of the present invention, Figure 1 As shown, the detection switch 30 is a travel switch, which includes a switch body and a connecting rod 31. One end of the connecting rod 31 is connected to the switch body, and the other end of the connecting rod 31 is rotatably connected to the second end 22. The end face of the second end 22 is an arc cylinder.

[0071] By setting the end face of the second end 22 to a circular arc cylinder, it is easier to prevent the connecting rod 31 from interfering with the end face of the second end 22 during the process of the second end 22 driving the connecting rod 31 to rotate, thereby further reducing the design difficulty of the landing detection device 100.

[0072] In some embodiments of the present invention, Figure 2 As shown, the detection switch 30 is a proximity switch, the end surface of the second end 22 is an arc cylinder, and a matching protrusion 221 is formed on the end surface of the second end 22. In the initial position, the proximity switch is opposite to the matching protrusion 221.

[0073] By providing the matching protrusion 221 , the material usage of the trigger member 20 can be reduced, thereby reducing production costs, while ensuring that the distance between the second end 22 and the proximity switch meets the detection requirements of the proximity switch.

[0074] In some embodiments of the present invention, Figure 1 As shown, the landing detection device 100 further includes: a detection bracket 40, the detection switch 30 is arranged on the detection bracket 40, and the detection bracket 40 is suitable for being connected to the conveying bracket 220 of the conveying system.

[0075] It is understood that the structure of the detection bracket 40 is relatively simple compared to the detection switch 30. Furthermore, during assembly, the detection switch 30 is typically first assembled to the detection bracket 40 and then connected to the conveying bracket 220. This provides the operator with greater operating space than directly assembling the detection switch 30 to the conveying bracket 220, thereby reducing assembly difficulty. During the design of the production system 1000, the detection switch 30 can be adapted to the conveying bracket 220 by adjusting the structure of the detection bracket 40, further reducing the design difficulty of the production system 1000.

[0076] In some embodiments of the present invention, Figure 1 As shown, the detection bracket 40 includes a first plate portion 41 and a second fastener 412. The first plate portion 41 is provided with a first fixing hole 411. The first fixing hole 411 is an oblong hole extending in the vertical direction. The second fastener 412 is adapted to pass through the first fixing hole 411 to achieve installation of the detection bracket 40 on the conveying bracket 220. Thus, during the assembly process, by adjusting the vertical position of the second fastener 412 in the first fixing hole 411, the detection switch 30 can be adjusted vertically relative to the conveying bracket 220. This reduces the difficulty of aligning the position of the detection switch 30 with the trigger member 20, thereby further reducing the design and assembly difficulty of the production system 1000.

[0077] In some embodiments of the present invention, the position of the detection switch 30 relative to the detection bracket 40 in the conveying direction of the conveying system is adjustable. This further reduces the difficulty of aligning the position of the detection switch 30 with the trigger member 20, thereby further reducing the design and assembly difficulty of the production system 1000.

[0078] In some embodiments of the present invention, Figure 1 As shown, the detection bracket 40 also includes: a second plate portion 42 and a third fastener 422. The second plate portion 42 is provided with a second fixing hole 421. The second fixing hole 421 is an oblong hole, and the second fixing hole 421 extends along the conveying direction of the conveying system. The third fastener 422 passes through the second fixing hole 421 to connect the second plate portion 42 to the detection switch 30.

[0079] In this way, by adjusting the position of the third fastener 422 in the second fixing hole 421, the position of the detection switch 30 relative to the detection bracket 40 in the conveying direction can be adjusted, and the connection relationship between the detection switch 30 and the detection bracket 40 is relatively simple, which can reduce the difficulty of assembly.

[0080] Reference below Figures 1-4 A production system 1000 according to an embodiment of the second aspect of the present invention is described.

[0081] According to the production system 1000 of the second embodiment of the present utility model, Figure 1-Figure 3 As shown, it includes: a conveying mechanism and the above-mentioned landing detection device 100 according to the embodiment of the first aspect of the present utility model.

[0082] Specifically, the conveying mechanism includes a conveyor belt 210, a conveyor bracket 220 and a support platform 230. The conveyor belt 210 is mounted on the conveyor bracket 220. The support platform 230 is suitable for receiving the workpiece falling from the conveyor belt 210. The first end 21 is arranged side by side with the support platform 230. In the initial position, the upper surface of the first end 21 extends upward beyond the support platform 230. In the trigger position, the first end 21 abuts against the lower side of the workpiece.

[0083] During the operation of the production system 1000, the workpiece is conveyed on the conveyor belt 210. When the workpiece reaches the tail end of the conveyor bracket 220, the workpiece falls from the conveyor belt 210 and drives the first end 21 to move downward so that the trigger member 20 rotates from the initial position toward the trigger position. When the workpiece falls onto the support platform 230, the workpiece is supported on the support platform 230, and a part of the workpiece extends out of the support platform 230 to press the first end 21. At this time, the trigger member 20 is in the trigger position, the detection switch 30 is triggered, and the landing detection of the workpiece is completed.

[0084] When the workpiece is removed from the support platform 230 , the constraint of the workpiece on the first end 21 is released, and the trigger member 20 rotates from the trigger position to the initial position to complete the reset and prepare for the next landing detection.

[0085] According to the production system 1000 of the second embodiment of the present invention, by providing the above-mentioned landing detection device 100 according to the first embodiment of the present invention, the reliability of the production system 1000 during operation can be improved.

[0086] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a third buffer member 240 is provided on the support platform 230 , and the support platform 230 receives the workpiece through the third buffer member 240 .

[0087] By providing the third cushioning member 240, when the workpiece falls onto the support platform 230, the third cushioning member 240 can absorb a portion of the impact force between the workpiece and the support platform 230, thereby reducing the probability of damage to the workpiece and the support platform 230, further improving the reliability of the production system 1000 during operation and increasing the yield rate during the production process.
