Description

Technical Field

[0001] The present invention relates to a conveying device with a transmission mechanism, and in particular to a conveying device with a high-safety transmission mechanism applied in the technical field related to conveying equipment. Background Art

[0002] In the prior art, the conveying equipment generally sets the slide rail for transmission above the crossbeam, and the crossbeam is generally narrow, so generally only a single track can be set. However, the stability of the single track is relatively poor, so the prior art was later improved to set a double slide rail.

[0003] The double slide rails in the prior art are generally arranged on two beams, resulting in a large footprint. For example, the specification of Chinese patent CN115676356A discloses a three-axis detection and grasping mechanism, and Chinese patent CN111762378B discloses an end-gripping and stacking device and a method of use of a finished tile packaging production line. In addition, due to the arrangement of the double slide rails, the running consistency of the two sliders on the slide rails is prone to certain deviations. In the early stage of the deviation, it is difficult to detect due to the small deviation amplitude. After the deviation accumulates to a certain extent, when the workpiece or the robot arm is transmitted and conveyed, jamming, transmission problems and the like are prone to occur, resulting in the transported target object easily deviating from the target position after transportation, affecting the accuracy of transportation, and may also cause physical damage to the slide rail after a long time. Summary of the invention

DETAILED DESCRIPTION

[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1-2 FIG. 1 shows a conveying device with a high-safety transmission mechanism, comprising a crossbeam 1 and a transverse back plate 2 matched with the crossbeam 1, wherein the end of the transverse back plate 2 away from the crossbeam 1 is connected to a longitudinal movement component 3, and the upper end of the crossbeam 1 and the end of the transverse back plate 2 away from the crossbeam 1 are both installed with a linear drive unit, the linear drive unit comprises a motor 41, a reducer connected to the rotating end of the motor 41, a screw rod 42 fixedly connected to the rotating end of the reducer, and a bearing seat 401 connected to the end of the screw rod 42 away from the motor 41 through a bearing, a nut 43 is threadedly connected to the screw rod 42, and a transition plate 11 is fixedly inlaid on the upper end of the crossbeam 1 and the surface of the end close to the transverse back plate 2, and a transverse slide rail 12 is fixedly connected to the transition plate 11 by screws, as shown in FIG. Figure 4The end of the transverse moving back plate 2 close to the cross beam 1 is fixedly connected with a lining plate 21, and the lower end of the lining plate 21 and the end of the transverse moving back plate 2 close to the cross beam 1 are fixedly connected with a group of transverse slide blocks 13, and the two groups of transverse slide blocks 13 are respectively slidably matched with the two transverse slide rails 12, and the end of the transverse moving back plate 2 close to the longitudinal moving assembly 3 is fixedly connected with two groups of vertical slide blocks symmetrical about the screw rod 42, and the longitudinal moving assembly 3 is installed with two vertical slide rails matching the two groups of vertical slide blocks at one end close to the transverse moving back plate 2. The nut 43 on the transverse moving back plate 2 is fixedly connected to the middle part of the longitudinal moving assembly 3, and the nut 43 on the cross beam 1 is fixedly connected to one of the transverse slide blocks 13. The transverse linear drive unit can drive the transverse moving back plate 2 to carry the longitudinal moving assembly 3 to move horizontally, and the vertical linear drive unit can drive the longitudinal moving assembly 3 to move vertically, so that the longitudinal moving assembly 3 as a whole has the functions of moving left, right, up and down, which is convenient for moving the workpiece or mechanical arm carried on the longitudinal moving assembly 3; It is worth noting that, in specific implementation, the longitudinal movement component 3 may be equipped with relevant clamp components for clamping the workpiece, and may also be equipped with a robotic arm for operation. Through this conveying device, the target object can be transported horizontally and vertically.

[0020] A linkage unit is fixedly connected between the two sets of horizontal sliders 13, such as Figure 3-4 The linkage unit includes two linkage rods 5 respectively fixedly connected to the two groups of horizontal sliders 13 and a detection rod 6 connected between the two linkage rods 5, one end of the detection rod 6 is fixedly connected to one of the linkage rods 5, and the other end of the detection rod 6 is in contact with the other linkage rod 5, and the fixed ends of the two detection rods 6 are not located on the same side.

[0021] The two transverse slide rails 12 used for transverse movement are arranged on two planes of the same crossbeam, thereby effectively improving the stability during transverse movement, and through the setting of the linkage unit, the transmission consistency of the two sets of transverse sliding blocks 13 in the transverse movement on the corresponding transverse slide rails 12 can be effectively monitored, and the abnormal area can be pinpointed for timely and targeted maintenance, effectively ensuring the stability and accuracy of the transmission and transportation of the target object.

[0022] like Figure 7The detection rod 6 includes a fixed rod 61 fixedly connected to the linkage rod 5, a follower rod 62 in contact with another linkage rod 5, and an elastic tube 63 fixedly connected therebetween. One end of the fixed rod 61 facing the follower rod 62 is fixedly connected to a limited position contact rod 64. A detection groove is drilled in the follower rod 62, and a double-detection unit is arranged inside the detection groove. The end of the limit contact rod 64 extends into the detection groove and contacts the double-detection unit. The end of the double-detection unit away from the fixed rod 61 is fixedly connected to a control rope 9. A wire hole is also drilled at the end of the follower rod 62. The control rope 9 passes through the wire hole and is fixedly connected to the relative linkage rod 5. The double-detection unit contacts It includes a positioning block 71 fixedly connected to the detection groove, a pressure sensor 72 installed at one end of the positioning block 71 close to the limit touch rod 64, and a tension sensor 73 fixedly installed at the other end of the positioning block 71. The limit touch rod 64 and the pressure sensor 72 are in contact with each other. The connection point between the control rope 9 and the double detection unit is located at the detection end of the tension sensor 73. When the sliding consistency of the two sets of horizontal sliders 13 on the two horizontal slide rails 12 is good, the two linkage rods 5 are relatively still. At this time, the two detection rods 6 between the two are not subjected to force or are subjected to very little force. When the sliding consistency of the two sets of horizontal sliders 13 deteriorates, such as Figure 5 When the upper horizontal slider 13 moves faster than the lower horizontal slider 13, the linkage rod 5 connected to the upper side will generate a squeezing force on the two detection rods 6, thereby squeezing the elastic tube 63, and the limit contact rod 64 contacts the pressure sensor 72, so that the pressure sensor 72 generates force data, and the greater the deviation, the greater the data on the pressure sensor 72. Figure 6 When the upper horizontal slider 13 is slower than the lower horizontal slider 13, the two linkage rods 5 tend to separate from each other, causing the control rope 9 to produce a pulling force on the tension sensor 73, thereby causing it to generate force data. Similarly, the greater the deviation, the greater the data on the tension sensor 73.

[0023] In summary, based on the data changes of the pressure sensor 72 and the tension sensor 73, the sliding conditions of the corresponding transverse slide blocks 13 on the two transverse slide rails 12 can be effectively judged, and the stability of the transverse back plate 2 during transverse movement can be judged. When the data is greater than the pre-set thresholds on the pressure sensor 72 and the tension sensor 73, the staff can perform corresponding maintenance in a timely manner, thereby effectively ensuring that good stability can be maintained during the entire transportation process of the target object, so that the target object is not prone to deviation when it reaches the target point.

[0024] It is worth noting that when the follower rod 62 contacts the corresponding linkage rod 5, the control rope 9 is already in a straightened state, and in actual implementation, since the two sets of horizontal sliders 13 are fixed on the horizontal movement back plate 2, the actual deviation will not be large and will not cause the following Figure 6 There is a large gap between the detection rod 6 and the linkage rod 5, and the figure is relatively exaggerated only for the convenience of understanding.

[0025] The position control rope 9 is a double rope structure, and both ropes are non-elastic structures. One rope is in a horizontally stretched state, and the other rope is in a relaxed state, and the length difference between the two ropes does not exceed 5mm. When a deviation occurs, the position control rope 9 can generate tension on the tension sensor 73, so that it generates force data, thereby improving the movement monitoring effect of the two horizontal sliders 13, and the position control rope 9 can also have a certain pulling and suppressing effect on the movement deviation of the two horizontal sliders 13. When the deviation between the two is large, the shorter rope will be disconnected, so that the data on the corresponding tension sensor 73 will be briefly reset to zero, and then the longer rope will be straightened again to suppress the deviation, so that the tension sensor 73 will generate force data again. Based on the data changes of the tension sensor 73, the staff can be further reminded of the criticality of the deviation of the two sets of horizontal sliders 13, so that the staff has a certain urgency and the maintenance work can be more timely.

[0026] The two transverse slide rails 12 for transverse movement are arranged on two planes of the same crossbeam 1, thereby increasing the span between the two transverse slide rails 12 and effectively improving the stability. Compared with the setting of two crossbeams, the floor space is effectively reduced and the space requirement is reduced. In addition, with the setting of the linkage unit, the transmission consistency of the two sets of transverse slide blocks 13 in the transverse movement on the corresponding transverse slide rails 12 can be effectively monitored. Under the action of the double inspection unit, the transverse slide block 13 with slower transmission can be effectively located, which is convenient for pinpointing abnormal areas and timely targeted maintenance, effectively ensuring the stability and accuracy of the transmission and transportation of the target object.

[0027] The second implementation method: This embodiment is based on the first embodiment, and a looseness monitoring unit is added, and the rest of the parts are consistent with the first embodiment.

[0028] Figure 9-10 As shown, a looseness monitoring unit is also provided outside the detection rod 6, and an annular groove is bored on the inner wall of the mouth of the wire hole on one side of the linkage rod 5. The looseness monitoring unit includes two annular light strips 10 respectively connected to the outside of the fixed rod 61 and the follower rod 62, a measuring ring 8 arranged in the annular groove, and a miniature camera installed on the transverse back plate 2. The two detection rods 6 are both located in the shooting area of ​​the miniature camera. When the two transverse slide blocks 13 become loose, the control rope 9 will be difficult to be horizontal, but will shake with the shaking caused by the loosening of the transverse slide block 13, thereby squeezing the measuring ring 8, so that the annular light strip 10 is triggered to light up. When the shaking is severe, the control rope 9 continuously squeezes the two sensing semi-rings 81 back and forth, which will cause the two annular light strips 10 to be continuously and alternately touched, thereby presenting a flashing state. At this time, the miniature camera can obtain the picture and transmit it back to the control center, thereby reminding the staff of the looseness.

[0029] The measuring ring 8 includes two symmetrical sensing semi-rings 81, two supporting plates 82 respectively located between the ends of the two sensing semi-rings 81, and self-resetting switches 83 respectively installed at one end of the two supporting plates 82 away from each other. The two self-resetting switches 83 are respectively used to control the opening and closing of the two annular light strips 10. An end of the sensing semi-ring 81 facing the corresponding self-resetting switch 83 is fixedly connected with a convex contact piece 801, and the convex contact piece 801 is communicated with the sensing semi-ring 81. The inner ring of the sensing semi-ring 81 is an elastic structure, and the rest of the sensing semi-ring 81 is a uniform hard and fixed structure. The interior of the sensing semi-ring 81 is saturated with deionized water. When the sensing semi-ring 81 is squeezed by the control rope 9, the deionized water inside it will squeeze the convex contact piece 801 and cause it to deform outward, thereby squeezing the self-resetting switch 83 and causing it to be pressed, thereby triggering the corresponding annular light strip 10, so that when there is looseness between the horizontal sliding block 13 and the horizontal sliding rail 12, the annular light strip 10 is lit.

[0030] In order to adapt to the different setting planes of the two transverse slide rails 12, the two measuring rings 8 are set in different directions, such as Fig.12 , the bearing plate 82 on a measuring ring 8 is in a horizontal state, which corresponds to the horizontal slide rail 12 and the horizontal slider 13 below. When the two are loose, the horizontal slider 13 will be offset in the up and down directions, causing the control rope 9 to shake in the up and down directions, such as Fig.11 The other supporting plate 82 is in a vertical state, which corresponds to the upper horizontal slide rail 12 and the horizontal slide block 13. When the two are loose, the horizontal slide block 13 will be offset in the front-to-back direction, causing the control rope 9 to shake in the front-to-back direction. By setting two measuring rings 8 in different directions, when the above situation occurs, the sensing half ring 81 can be squeezed to light up the corresponding annular light strip 10, thereby effectively ensuring the monitoring effect of the loose monitoring unit.

[0031] In summary, the two transverse slide rails 12 used for transverse movement are arranged on two planes of the same crossbeam, so as to increase the span between the two transverse slide rails 12 and effectively improve the stability. In addition, with the setting of the linkage unit, the transmission consistency of the two groups of transverse sliders 13 in the transverse movement on the corresponding transverse slide rails 12 can be effectively monitored. Under the action of the double inspection unit, the transverse slider 13 with slower transmission can be effectively located, which is convenient for pinpointing abnormal areas and timely targeted maintenance, effectively ensuring the stability and accuracy of the transmission and transportation of the target object. At the same time, with the setting of the looseness monitoring unit, the stability of the assembly between the transverse slider 13 and the transverse slide rail 12 can also be monitored, so as to timely detect the looseness abnormality between the two, thereby effectively ensuring the stability and safety of the transmission process.

[0032] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
