Description

Technical Field

[0001] The present invention belongs to the technical field of suspension string pre-assembly processing and production, and more specifically, relates to a connecting wire clamp circulating feeding unit of a suspension string pre-assembly processing production line. Background Art

[0002] The rapid development of my country's railway construction has put forward new requirements for the process quality standards of relevant components in the railway industry, and the construction and maintenance of running lines have become increasingly demanding. In the railway running line, the catenary is a vital component to ensure the normal operation of the railway. It is connected to the electric railway power supply line and is responsible for supplying power to the entire electric locomotive traction system and train ancillary equipment.

[0003] In the train's contact network system, the dropper is an indispensable structure, which is mainly used to stably hang the contact wire under the load-bearing cable, ensure the stability and safety of the contact wire setting, and ensure that the contact wire can be reliably matched with the pantograph on the top of the train.

[0004] During the pre-assembly process of catenary droppers, the use of connecting clamps is often indispensable. However, existing processes such as loading, clamping, and pressing connecting clamps often rely on skilled workers. Furthermore, the wide variety of sizes and styles of connecting clamps, combined with their large usage, lead to cumbersome manual operations, high labor intensity, low production efficiency, and high hanging process costs. Furthermore, manual assembly of connecting clamps makes it difficult to guarantee product quality, resulting in poor performance consistency and a low pass rate. This also creates the risk of the connecting clamps failing during later applications.

[0005] In addition, in the existing pre-assembly production of suspension strings, there is no concept of connecting wire clamp caching. When workers need to assemble a suspension string, they have to take two connecting wire clamps. The above-mentioned defects of manual operation also exist, and the continuity of the suspension string processing is poor. Summary of the Invention

[0006] In response to the above defects or improvement needs of the prior art, the present invention provides a connecting wire clamp circulating loading unit for an intelligent suspension string pre-assembly processing production line, which can effectively realize the caching and continuous automatic loading of connecting wire clamps during the suspension string processing process, ensure the continuity and accuracy of the connecting wire clamp loading process, and reduce the amount of manual labor in the connecting wire clamp loading process.

[0011] Preferably, a direction selection mechanism is further provided at the entrance of the spiral feeding channel for allowing a connection wire clamp with a set posture to pass through.

[0012] Preferably, the direction selection mechanism includes a scraper installed on the spiral feeding channel and a return spring connected to the scraper for returning the scraper to its original position. The return spring is located in the spiral feeding channel. One end of the scraper is exposed from the spiral feeding channel and can be pressed into the spiral feeding channel by the bottom of the connecting wire clamp.

[0013] Preferably, the tangent line at the outlet of the spiral feeding channel is perpendicular to the discharge channel of the connecting wire clamp.

[0014] Preferably, a blocking plate is vertically provided on one side of the connecting wire clamp cache mold close to the connecting wire clamp discharge channel, so as to block the connecting wire clamp in the connecting wire clamp discharge channel after the connecting wire clamp in the mold rises.

[0015] Preferably, the connecting wire clamp discharge channel includes a channel bottom plate and two side plates installed on the channel bottom plate, and the distance between the two channel side plates at the entrance of the connecting wire clamp discharge channel is greater than the distance between the two channel side plates at the exit of the connecting wire clamp discharge channel.

[0016] Preferably, the connecting wire clamp cache mold includes a limit stop and a support platform; the limit stop is used to block the movement of the connecting wire clamp along the forward direction of the connecting wire clamp discharge channel, and the support platform is used to support the connecting wire clamp coming out of the connecting wire clamp discharge channel.

[0017] Preferably, the connecting wire clamp cache mold further includes a guide platform located above the supporting platform, so as to guide the connecting wire clamp into the connecting wire clamp cache mold.

[0018] Preferably, arc-shaped grooves are respectively provided on opposite sides of the two clamping jaws of the pneumatic clamping jaw to clamp the straight end of the connecting wire clamp.

[0020] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0021] 1) The present invention constructs a connecting wire clamp vibration plate and a connecting wire clamp discharge channel to guide the connecting wire clamps one by one to the connecting wire clamp cache mold to wait for being grabbed and loaded, thereby providing conditions for the connecting wire clamp loading unit to automatically and continuously supply the connecting wire clamps, replacing traditional manual loading, and has the characteristics of high efficiency, precision, and high degree of automation. It solves the problem of automatic loading and assembly of connecting wire clamps, constitutes an important link in the loading of the automatic production line for pre-assembly of suspension strings, reduces the extra manual labor introduced by the loading and caching of connecting wire clamps during the suspension string processing process, reduces the labor intensity and labor cost of suspension string processing, improves the degree of automation of suspension string assembly, and reduces the cost of suspension string assembly.

[0023] 3) The present invention constructs the discharge channel of the connecting wire clamp to be wider at the entrance and narrower at the exit, which not only prevents blockage at the entrance but also ensures the smoothness of individual discharge at the exit.

[0024] 4) The present invention sets a blocking plate on the connecting wire clamp cache mold corresponding to the outlet end of the connecting wire clamp discharge channel, and uses the corresponding movement of the blocking plate to close the outlet end of the connecting wire clamp discharge channel when a single connecting wire clamp is supporting and loading, thereby preventing the connecting wire clamp in the connecting wire clamp discharge channel from falling, ensuring that the connecting wire clamps in the connecting wire clamp discharge channel can be accurately taken out one by one, and further improving the accuracy of the connecting wire clamp taking out.

[0031] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention 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 merely for the purpose of explaining the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0032] like Figures 1 to 4 As shown, a connecting wire clamp circulating feeding unit of an intelligent suspension string pre-assembly processing production line includes a frame, a connecting wire clamp buffer unit 420 and a connecting wire clamp feeding unit 50, wherein:

[0033] The connecting wire clamp cache unit includes 420, including a connecting wire clamp vibration disk 4201, a connecting wire clamp discharge channel 4202, a connecting wire clamp feeding cylinder 4203 and a connecting wire clamp cache mold 4204. The connecting wire clamp vibration disk 4201 is installed on the frame. The connecting wire clamp vibration disk 4201 includes a connecting wire clamp vibration disk body 4205 for storing the connecting wire clamp 4208 and a spiral feeding channel 4206 installed on the inner wall of the connecting wire clamp vibration disk body 4205. The outlet of the spiral feeding channel 4206 is connected to the inlet of the connecting wire clamp discharge channel 4202. The height of the outlet of the connecting wire clamp discharge channel is less than the height of the inlet of the connecting wire clamp discharge channel.

[0034] The connecting wire clamp loading cylinder 4203 is installed on the frame, and the connecting wire clamp cache mold 4204 is installed on the output shaft of the connecting wire clamp loading cylinder 4203 to drive the connecting wire clamp cache mold 4204 to move up and down. The connecting wire clamp cache mold 4204 is correspondingly arranged at the outlet of the connecting wire clamp discharge channel 4202, and the connecting wire clamp cache mold 4204 is provided with an accommodating space 4207 to accommodate the connecting wire clamp 4208 coming out of the connecting wire clamp discharge channel 4202. The two ends of the connecting wire clamp discharge channel 4202 are respectively connected to the spiral loading channel and the connecting wire clamp cache mold 4204, which are used to send the connecting wire clamps 4208 one by one to the connecting wire clamp cache mold 4204, and realize the caching of several connecting wire clamps 4208 before loading; the connecting wire clamp cache mold 4204 is used to realize the one-by-one collection of the connecting wire clamps 4208 in the connecting wire clamp discharge channel 4202, and realize the support and limitation of each connecting wire clamp 4208, so that the connecting wire clamp loading unit can load it to the next workstation; the collection point can use manual assistance to adjust the posture of the connecting wire clamp 4208 and collect materials, or it can use a six-axis robot for automatic collection.

[0035] The connecting wire clamp loading unit 50 includes a six-axis robot 52 and a pneumatic gripper 55. The lower end of the six-axis robot 52 is mounted on a frame, and the pneumatic gripper 55 is mounted at the distal end of the six-axis robot 52. The lower end of the six-axis robot 52 has a robot base 51. The pneumatic gripper 55 includes a clamping cylinder and two grippers mounted on the clamping cylinder, which are used to clamp the connecting wire clamp on the connecting wire clamp buffer mold to the loading position. The two grippers are a first gripper 551 and a second gripper 552, respectively. They are located between a first clamping plate 553 and a second clamping plate 554 on the clamping cylinder. A power control unit 56 is also mounted on the robot base 51 to control the movement of each axis of the six-axis robot 52. Preferably, the pneumatic gripper 55 is mounted to the distal end of the six-axis robot 52 via a rotating arm 53, which drives the rotating arm 53 to rotate. There are multiple pneumatic grippers 55, and they are evenly distributed around the circumference. Preferably, arc-shaped grooves are respectively provided on the opposite sides of the two clamping jaws of the pneumatic clamping jaws 55 to facilitate clamping the straight end of the connecting wire clamp 4208.

[0036] Of course, during actual loading, depending on the processing situation, the pneumatic gripper 55 can be used to hold only the connecting wire clamp for a period of time, or it can also be used to hold and load crimped tubes, heart-shaped rings, and connecting wire clamps during string pre-assembly production. The number of pneumatic grippers 55 can be adjusted based on processing needs. The six-axis robot 52 and the pneumatic gripper 55, specifically designed for connecting wire clamps, effectively replace traditional manual loading, offering high efficiency, precision, and a high degree of automation. This solves the problem of automated loading and assembly of connecting wire clamps and constitutes a key component of the automated loading process for string pre-assembly.

[0037] Reference Figure 4A direction selection mechanism 4216 is also provided at the entrance of the spiral feeding channel 4206 for cooperating with the inclined surface 4219 on the connecting wire clamp 4208, thereby allowing the connecting wire clamp 4208 with a set posture to enter the spiral feeding channel. Referring to the accompanying drawings, as a preferred embodiment, the selection mechanism 4216 includes a scraper 4217 installed on the spiral feeding channel and a return spring 4218 connected to the scraper 4217 for returning the scraper 4217. The return spring 4218 is located in the spiral feeding channel, and one end of the scraper 4217 is exposed from the spiral feeding channel and can be pressed into the spiral feeding channel by the bottom of the connecting clamp 4208. The scraper 4217 can cooperate with one of the inclined surfaces 4219 on the connecting clamp 4208, and the inclined surface 4219 can pass through the scraper 4217, thereby allowing the connecting clamp 4208 to pass through the scraper 4217. If the posture of the connecting clamp 4208 is not appropriate, when other parts, especially the end, are in hard contact with the scraper 4217, it will be blocked and fall from the spiral feeding channel. The scraper 4217 can be a scraper with a tip, or a rod, and the elastic force of the return spring 4218 should be appropriate to ensure that the scraper 4217 can be pressed down by the connecting clamp 4208 and can return to its original position. The return spring 4218 can be an existing spring 4218 such as a compression spring 4218 or a torsion spring.

[0038] Alternatively, the selection mechanism 4216 includes a vertical plate installed on the spiral loading channel 4206, and the vertical plate is installed on the side of the spiral loading channel 4206 away from the inner wall of the connecting wire clamp vibration disk body 4205. The distance between the vertical plate and the inner wall of the connecting wire clamp vibration disk body 4205 is slightly larger than the maximum width of the connecting wire clamp 4208. The connecting wire clamp 4208 is only allowed to pass through the vertical plate along the longitudinal movement of the connecting wire clamp 4208 itself. The skewed connecting wire clamp 4208 cannot pass through and falls.

[0039] Furthermore, the tangent line at the exit of the spiral feeding channel 4206 is perpendicular to the connecting wire clamp discharge channel 4202, allowing the connecting wire clamp 4208 to enter the connecting wire clamp 4208 buffer mold in a set posture, facilitating the six-axis robot to retrieve the material. A limit plate can also be provided on the connecting wire clamp vibration plate body 4205 at the position corresponding to the exit of the spiral feeding channel 4206 to restrict the connecting wire clamp 4208 from further movement, so that the connecting wire clamp 4208 can only enter the connecting wire clamp discharge channel 4202.

[0040] Furthermore, a blocking plate 4209 is vertically provided on one side of the connecting wire clip cache mold 4204 near the connecting wire clip discharge channel 4202. This is used to block the connecting wire clip 4208 in the connecting wire clip discharge channel 4202 after the connecting wire clip 4208 in the mold rises. By correspondingly moving the blocking plate 4209, the blocking plate 4209 can close the outlet end of the connecting wire clip discharge channel 4202 when a single connecting wire clip 4208 is supporting and loading the material, thereby preventing the connecting wire clip 4208 in the connecting wire clip discharge channel 4202 from falling, ensuring that the connecting wire clips 4208 in the connecting wire clip discharge channel 4202 can be accurately removed one by one, further improving the accuracy of the connecting wire clip 4208 removal.

[0041] Furthermore, the connecting wire clamp discharge channel 4202 includes a channel bottom plate 4210 and two side plates 4211 mounted on the channel bottom plate 4210. The distance between the two channel side plates 4211 at the entrance of the connecting wire clamp discharge channel 4202 is greater than the distance at the exit of the connecting wire clamp discharge channel 4202. One of the side plates 4211 is a fixed side plate 4211, and the other side plate 4211 is a movable side plate 4211. The movable side plate 4211 is movable relative to the fixed side plate 4211 to adjust the width of the connecting wire clamp discharge channel 4202. The connecting wire clamp discharge channel 4202 is constructed to be wider at the entrance and narrower at the exit, which prevents blockage at the entrance and ensures smooth single discharge at the exit. Furthermore, the overall width of the channel can be timely adjusted by moving the movable side plates 4211, and connecting wire clamps 4208 of different sizes and shapes can all automatically adjust to adapt.

[0042] Furthermore, the connecting wire clamp cache mold 4204 includes a limit stop 4212 and a support platform 4213; the limit stop 4212 is used to block the movement of the connecting wire clamp 4208 along the forward direction of the connecting wire clamp discharge channel 4202, and the support platform 4213 is used to support the connecting wire clamp 4208 coming out of the connecting wire clamp discharge channel 4202.

[0043] Furthermore, the connecting wire clamp cache mold 4204 also includes a guide platform 4214 located above the support platform 4213, for guiding the connecting wire clamp 4208 into the connecting wire clamp cache mold 4204. A plurality of long holes are also provided on the connecting wire clamp cache mold 4204. The guide platform 4214 can adjust its position within the long holes to better adapt to the shape and position of one end of the connecting wire clamp 4208 with a circular hole, so that the connecting wire clamp 4208 can more conveniently enter the accommodating space 4207 of the connecting wire clamp cache mold 4204.

[0044] Furthermore, a notch 4215 is provided on the connecting wire clamp cache mold 4204 so that the pneumatic clamp connected to the end of the six-axis robot can clamp the connecting wire clamp 4208.

[0045] The connecting wire clamp 4208 loading and caching device suitable for contact network suspension string processing in the present invention has a simple structure and is easy to operate. It adopts a connecting wire clamp vibration disk 4201 to vibrate and convey a large number of connecting wire clamps 4208 stored therein, and adopts a tangentially contracted connecting wire clamp 4208 channel to arrange the connecting wire clamps 4208 in a single row linearly. The connecting wire clamps 4208 discharged from the end of the connecting wire clamp discharge channel are supported and limited one by one by a connecting wire clamp cache mold 4204, creating favorable conditions for grasping by the grasping equipment of the next workstation; thereby realizing the caching of the connecting wire clamp 4208 and continuous automatic loading.

[0046] The connecting wire clamp circulating feeding unit of the present invention has a simple structure and is easy to operate. It adopts a connecting wire clamp vibration disk 4201 to vibrate and convey a large number of connecting wire clamps stored therein, and adopts a connecting wire clamp discharge channel 4202 to arrange the connecting wire clamps 4208 in a single row linearly. The connecting wire clamps discharged from the end of the connecting wire clamp discharge channel 4202 are supported and limited one by one by a connecting wire clamp cache mold 4204, creating favorable conditions for grasping the connecting wire clamp feeding unit 50; at the same time, by setting a multi-degree-of-freedom six-axis robot 52 and a rotating arm 53 thereon, and utilizing the corresponding setting of the pneumatic clamp 55, the accurate clamping of the connecting wire clamp 4208 at the material picking station and the corresponding transfer of the connecting wire clamp 4208 to the upper feeding station are accurately realized, thereby realizing the continuous automation of caching, picking and loading of the connecting wire clamp 4208 without manual operation, reducing labor intensity, improving production efficiency, improving product quality and stability of batch operations, reducing the cost of string hanging processing, and having good application prospects and promotion value.

[0049] S2. According to the type of the connecting wire clamp 4208 inserted, move and adjust the movable side plate 4211 of the connecting wire clamp discharge channel 4202 to adjust the width of the connecting wire clamp discharge channel 4202;

[0050] S3. Vibrate the connecting wire clamp vibration plate 4201 to guide the connecting wire clamps 4208 in the plate to the entrance of the connecting wire clamp discharge channel 4202 and move them along the connecting wire clamp discharge channel 4202. Finally, the outermost connecting wire clamps 4208 are sent into the connecting wire clamp buffer mold 4204.

[0051] S4. Control the connecting wire clamp feeding cylinder 4203 to operate, so that the connecting wire clamp buffer mold 4204 drives the connecting wire clamp 4208 to rise accordingly, so that the connecting wire clamp 4208 is raised to the material removal position, waiting to be grabbed by the pneumatic clamp 55. At this time, the blocking plate 4209 completes the blocking of the connecting wire clamp discharge channel outlet 4202, and the remaining connecting wire clamps 4208 in the connecting wire clamp discharge channel 4202 will not fall;

[0052] S5. Control the two clamps to be in an open state, and simultaneously control the six-axis robot 52 and the rotating arm 53 to work accordingly, so that the two clamps move to the connection clamp 4208 on the connection clamp cache mold 4204, and then control the two clamps to close to complete the clamping of the connection clamp 4208;

[0053] S6. Control the six-axis robot 52 and the rotating arm 53 to work accordingly, and send the connecting wire clamp 4208 from the material taking position to the loading station. After the material is loaded into place, release the two clamping claws to complete the loading of the connecting wire clamp 4208 at the loading station.

[0054] S7. Repeat steps S3 to S6 in sequence to complete the continuous automatic cycle loading of multiple connecting wire clips 4208.

[0055] It will be easily understood by those skilled in the art that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
