They are merely for the purpose of facilitating the description of this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] The terms "mounting", "connecting", "connecting", "fixing" and the like in the present application should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the internal connection of two elements, or the interaction relationship of two elements, for those skilled in the art, the above-mentioned terms can be understood according to the specific meaning of the terms in the present application.

[0031] As introduced in the background, the deficiencies existing in the prior art, in order to solve the above technical problems, the present application provides a guide ring loading device which can quickly guide the centering of the guide groove.

[0032] The guide ring loading device disclosed in the embodiment can quickly guide the centering of the guide groove, which mainly comprises an automatic dispensing machine 1, a dispensing sliding platform, a pre-clamping mechanism 8, a centering guide groove mechanism 9 and a related in-place detection sensor unit, wherein the automatic dispensing machine 1 is installed on the dispensing sliding platform and can move along the length direction of the dispensing sliding platform, the pre-clamping mechanism 8 and the centering guide groove mechanism 9 are also installed on the dispensing sliding platform, and the pre-clamping mechanism 8 and the centering guide groove mechanism 9 are located below the automatic dispensing machine 1, the pre-clamping mechanism 8 and the centering guide groove mechanism 9 are designed to be left-right symmetrical (symmetrical relative to the axis of the dispensing sliding platform); The specific arrangement number and spacing of the pre-clamping mechanism 8 and the centering guide groove mechanism 9 can be determined according to the length of the fishing rod, the number of placed guide rings and related assembly process.

[0033] From Figure 3 It can be seen that the upper part of the guide ring 50 to be installed in the embodiment is a circular ring, and the lower end is a transversely long strip, so the design idea of the centering loading device is:

[0034] Firstly, drive the parallel cylinder 18 to open the pre-clamping mechanism 8, put the fishing rod 7 from above, embed the tail of the fishing rod into the tail seat frame 6, then drive the cylinder to close the left V-groove type clamping jaw 19 and the right V-groove type clamping jaw 20 in the mechanism, complete the centering and clamping of the fishing rod 7, and then combine the dispensing machine coordinate system, the dispensing platform and the relative physical positions of each mechanism to complete the positioning of the fishing rod 7 in the workpiece coordinate system.

[0035] Secondly, the fish rod 7 is partially clamped by the centering guide groove mechanism 9 and then the automatic dispensing is formed. The centering guide groove mechanism 9 is opened and closed by driving the parallel cylinder 22, and the mechanism includes a spring clamp rod assembly and a centering guide groove assembly. The spring clamp rod assembly can center and partially clamp the shaft of the dispensing position of the fish rod, and the centering guide groove assembly can form two sets of centering grooves after being closed, i.e. the guide grooves formed by the left and right centering plates 32 and the guide grooves formed by the left and right centering columns 47. The dispensing machine 1 dispenses the upper edge surface of the fish rod 7 located below the guide groove of the left and right centering plates 32 through the dispensing head, and can dispense the positions of the fish rod where the guide ring needs to be placed at one time. After dispensing is completed, the dispensing head returns to the original point through the control program, and the next step is to place the guide ring 50.

[0036] Finally, the guide ring 50 is placed. When placing the guide ring, the upper ring surface of the hand-held guide ring is placed in the guide groove formed by the centering column 47, and the guide ring long foot is embedded in the guide groove formed by the centering plate 32 by pressing with the fingers, so that the guide ring 50 feeding is completed. Similar to the action of manually pressing the bullet into the magazine, the guide ring placement of other positions is the same as this step, and the guide ring feeding assembly is also completed by the guide groove pressing method. Then the centering guide groove mechanism and the pre-clamping mechanism are opened in turn by driving the cylinder, and the fish rod 7 with the bonded guide ring is taken off, thereby the centering feeding work of the guide ring can be quickly realized.

[0037] The specific mechanical structure, guide ring feeding operation and control process are as follows:

[0038] The workpiece coordinate system is established. In the X-axis direction, the platform is placed along the X-axis line, and corresponding position detection sensors such as the left limit sensor 12, the right limit sensor 16, the zero point sensor 13, the dispensing position one sensor 14 and the dispensing position two sensor 15 are placed along the axis. In the Y-axis direction, the platform can be placed directly below the Y-axis zero point. In the Z-axis direction, the height relationship between the dispensing head and the platform is recorded. In this way, the workpiece coordinate system of the dispensing platform and the subsequent centering device and the specific dispensing position of the fish rod is established.

[0039] As shown in Figure 1 The upper surface of the dispensing sliding platform is also provided with an aluminum profile bracket 2, a linear guide rail 3, a lockable slide 10, a tail seat frame 6, a tail seat frame bracket 4, a triangular connecting block 5 and the like. The linear guide rail 3 is arranged along the length direction of the aluminum profile bracket 2, and a plurality of lockable slides 10 are arranged on the linear guide rail 3. The lockable slides 10 are used to mount the pre-clamping mechanism 8 and the centering guide groove mechanism 9. After the number and spacing of the lockable slides 10 are determined, the lockable slides 10 can be locked through the pattern nut on the lockable slides 10.

[0040] The tail seat frame bracket 4 is mounted at one end of the linear guide rail 3, and the tail seat frame bracket 4 is connected with the tail seat frame 6 through the triangular connecting block 5.

[0041] As Figure 2 shown, the pre-clamping mechanism 8, mainly composed of parallel cylinder 18, cylinder support 17, left rod clamp 19 and right rod clamp 20, the left rod clamp 19 and the right rod clamp 20 are installed on the two clamps of the parallel cylinder 18 through screws, the left rod clamp 19 and the right rod clamp 20 are both designed as V-shaped slot structure, which can conveniently align and clamp the fishing rod 7, the parallel cylinder 18 is also connected with the cylinder support 17 through screws, and finally the cylinder support 17 is fixed on the lockable slide block 10, so that the pre-clamping mechanism can be manually slid and locked on the linear guide rail 3 according to the corresponding position. When working, the driving parallel cylinder 18 opens the pre-clamping mechanism, the fishing rod 7 is placed on it from above, the tail of the fishing rod is embedded into the tail seat 6, and then the cylinder 18 is driven to close the left rod clamp 19 and the right rod clamp 20 in the mechanism, so as to complete the alignment and clamping of the fishing rod axis, thereby completing the positioning of the fishing rod 7 on the dispensing platform.

[0042] The centering guide groove mechanism in the embodiment is shown in Figure 3 , mainly including spring rod clamp assembly and centering guide groove assembly, the mechanism is left-right symmetrical and can be opened or closed with the parallel cylinder 22.

[0043] Further, the spring rod clamp assembly includes two, which are arranged left-right symmetrically, and are driven to be opened or closed by a parallel cylinder 22, when opened, the fishing rod 7 can be placed on it from above, which aims to avoid the fishing rod 7 from shaking when the guide ring 50 is placed, and increase the stability of placement. The assembly is fixed on the main frame 30 and can move with the parallel cylinder 22 to clamp or release the fishing rod 7; the structure of each spring rod clamp assembly is shown in Figure 4 , including clamping rod 25, copper guide sleeve 27, clamping spring 26, guide plate 24, and clamping rod support 23; the copper guide sleeve 27 is assembled on the clamping rod support 23 through interference fit, one end (clamping end) of the clamping rod 25 is nested with the pre-clamping spring 26, passes through the inner hole of the copper guide sleeve 27 through sliding fit, the other end of the clamping rod 25 is designed with a guide bevel, which is fixed after passing through the guide plate 24 with a locking nut 28, and the extension length of the clamping rod 25 can be adjusted more conveniently through rotating the locking nut 28 and under the reaction force of the pre-clamping spring 26, so as to better adapt to the clamping of fishing rods 7 of different thicknesses, and the top wire 29 can be used to lock to avoid loosening of the locking nut 28 caused by reciprocating movement of the clamping rod 25. The end face of the clamping end of the clamping rod 25 is also designed with a V-shaped clamping groove to facilitate the alignment and clamping of the axis of the fishing rod 7.

[0044] Further, the centering guide groove assembly is also arranged symmetrically left and right, and can be opened or closed by the parallel cylinder 22 described above. When opened, the fishing rod 7 can be placed above it. The centering guide groove assembly is driven by the cylinder to form two groups of centering grooves, namely the guide grooves formed by the left and right centering plates 32 and the guide grooves formed by the left and right centering columns 47. It should be noted that the guide grooves formed by the left and right centering plates 32 are used to place the long strip feet of the guide ring, so the shape and position of the guide grooves match those of the long strip feet. The guide grooves formed by the left and right centering columns 47 are used to place the annular surface of the upper part of the guide ring, so the shape and position of the guide grooves match those of the annular surface. In summary, the positions and shapes of the guide grooves on the left and right centering plates 32 and the left and right centering columns 47 are different.

[0045] Further, in order to better adapt to different thicknesses of the fishing rod 7, the centering guide groove assembly is adjustable in the left and right width direction and the up and down height direction, as follows:

[0046] The mechanical structure of the left and right width adjustment of the two left and right centering plates 32 is as follows: the micro guide rail 34 is fixed in the bracket 31 by screws, a micro slider 33 is assembled on the micro guide rail 34, the centering plate 32 and the micro slider 33 are connected by screws 39, a threaded hole is opened at the end of the centering plate 32, a screw column 35 is nested with the threaded hole and the left and right extension springs 36, the other end of the screw column 35 passes through the bracket 31 and is locked by a lock nut 37. To prevent the lock nut 37 from loosening, after the distance between the guide grooves formed by the left and right centering plates 32 and the width of the long strip feet of the guide ring 7 are adjusted and matched, the top screw 38 can be tightened.

[0047] The mechanical structure of the up and down height adjustment of the two left and right centering plates 32 is as follows: on the one hand, the height adjustment column 41 is pressed into the corresponding assembly hole of the main frame body 30 by interference fit, on the other hand, the copper guide sleeve 42 is also pressed into the corresponding assembly hole of the bracket 31 by interference fit. The height adjustment column 41 passes through the nested upper and lower extension springs 43 and the inner hole of the copper guide sleeve 42 to form an organism that can be adjusted in height. Through the left and right rotation of the screw column 45, the height adjustment pressing plate 44 and the knurled nut 46, the corresponding components on the bracket 31 can be adjusted in height under the action of the spring force. After adjustment is completed, the knurled screw 40 can be tightened manually.

[0048] Further, the middle column support 48 is arranged at the front end of the bracket 31, and the middle column 47 is arranged on the support 48. The axis of the middle column 47 is parallel to the length direction of the middle plate 32. The middle column 47 can be extended and rotated in the hole of the support 48. The middle column 47 is provided with a middle slot on the clamping surface. Through the driving of the parallel cylinder 22, the left and right middle columns 47 can form a complete middle guide slot. According to the shape and angle of the ring surface of the guide ring 50, the middle column 47 can be correspondingly extended and rotated. After the middle slot is adjusted reasonably, the left and right middle columns 47 can be fixed through the locking jack 49.

[0049] The guide ring loading operation and control process are as follows:

[0050] After the automatic dispensing machine 1 is powered on, the X, Y and Z three axes are returned to zero by operating the equipment. The fishing rod 7 is placed manually. The parallel cylinder 18 is driven to pre-clamp the fishing rod 7. After the fishing rod 7 is clamped, the middle guide slot cylinder 22 is driven to center the middle guide slot mechanism. The spring clamp rod assembly in the mechanism can further clamp the fishing rod 7 locally to increase the stability during dispensing and placing the guide ring 50. The middle guide slot assembly in the mechanism can also form a complete middle guide slot. Next, the dispensing program is started to dispense. For example, in the X axis direction, the dispensing work at the corresponding position is controlled through the corresponding control program and the in-place detection plate 11, the related position sensors 14 and 15, etc. The position 1 is dispensed. The position 1 is moved to stop. The Z axis dispensing head is lowered and dispensed. After dispensing is completed, the Z axis is raised again. Then the position 2 is moved to dispense. Similarly, after the dispensing at all positions on the fishing rod is completed, the dispensing head is raised and returned to the original position. Finally, the guide ring 50 is placed. When the guide ring is placed, the upper ring surface of the guide ring is placed in the guide slot formed by the left and right middle columns. The long strip foot of the guide ring is embedded in the guide slot formed by the left and right middle plates by pressing with the fingers. The guide ring is bonded and loaded. The action is similar to the manual pressing of the bullet into the magazine. The placement of the guide ring at other positions is the same as the above step. The guide ring is loaded and assembled through the guide slot pressing. Then the cylinders are driven to open the middle guide slot mechanism 9 and the pre-clamping mechanism 8. The fishing rod 7 with the bonded guide ring 50 is taken out, and the centering and loading of the guide ring 50 can be quickly realized.

[0051] Finally, it should be noted that the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations.

[0052] The above merely provides the preferred embodiments of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the principles and technical scope of the present application shall fall into the scope of the present application.
