Description

Technical Field

[0001] This invention relates to the field of clamp rubber sleeve technology, and in particular to a method for applying rubber sleeves to clamp rubber sleeve equipment. Background Technology

[0002] Cable clamps, a common type of fastener, are mainly used for fixing and connecting components such as cables, utility poles, pipes, and towers. To prevent surface scratches caused by direct contact between the clamp body and the fixed component, and to increase the friction between the clamp and the fixed component, a rubber sleeve is usually fitted over the outside of the clamp's semi-circular body. The rubber sleeve must fit tightly against the clamp surface, and its upper and lower edges must hook onto the edges of the clamp body to ensure that it does not easily fall off after being fitted, thus meeting the actual usage requirements of the clamp.

[0003] Currently, the rubber sleeve application process for clamps is mainly done manually. The operator first manually opens the rubber sleeve so that the opening size of the rubber sleeve is larger than the outer diameter of the clamp body. Then, the clamp body is aligned with the opened rubber sleeve opening, and the clamp is slowly pushed into the rubber sleeve. The relative position of the clamp and the rubber sleeve is adjusted to ensure that the rubber sleeve evenly wraps around the clamp body and the edges fit tightly. Finally, the surface of the rubber sleeve is manually pressed to complete the rubber sleeve application.

[0004] The rubber sleeve is relatively soft, and its upper and lower edges naturally fit the body. When manually opening the rubber sleeve, continuous force needs to be applied, which is cumbersome and laborious. Each rubber sleeve application takes a long time, resulting in low overall efficiency of the clamp rubber sleeve application process. Summary of the Invention

[0005] To improve the efficiency of clamp sealing, this invention provides a method for sealing clamps using a clamp sealing device.

[0006] In a first aspect, the present invention provides a clamping and rubber fitting device, which adopts the following technical solution:

[0007] A clamp fitting device includes a workbench, a mounting base mechanism movablely mounted on the workbench for clamp fitting installation, a guiding mechanism for guiding the fitting, a pushing mechanism for pushing the fitting and fitting it into the clamp, and a cutting mechanism for cutting the fitting.

[0008] The guiding mechanism includes a guide bar that engages with the slot of the rubber sleeve and guides the movement direction of the rubber sleeve, and a support opening connected to the lower end of the guide bar for opening the slot of the rubber sleeve. The pushing mechanism abuts against the rubber sleeve and drives the rubber sleeve to move downward along the guide bar.

[0009] The mounting base mechanism has a feeding station and a rubber sleeve station. At the rubber sleeve station, one end of the clamp is aligned with the bottom end of the guide strip so that the rubber sleeve can be fitted into the clamp.

[0010] By adopting the above technical solution, one end of the rolled rubber sleeve is installed on the guide strip. During the sleeve application process, the pushing mechanism can pull and push the rubber sleeve, which can move down along the guide strip. When the clamp is in the sleeve application position, the rubber sleeve can be directly sleeved into the clamp after being expanded by the support at the lower end of the guide strip. After the pushing mechanism pushes the rubber sleeve completely into the clamp, the cutting mechanism can cut the rubber sleeve, thus completing the entire sleeve application process. In the above sleeve application process, except for the manual installation and feeding of the clamp, the rest of the sleeve application process can be automated by the equipment, which greatly improves the efficiency of clamp sleeve application.

[0011] Optionally, the pushing mechanism includes a bracket with upper and lower support seats, a drive screw rotatably mounted on the support seats, a drive motor that drives the drive screw to rotate, a pushing seat movably mounted on the drive screw, and a pushing component mounted on the pushing seat.

[0012] The pushing assembly includes a pressing cylinder fixed to the pushing seat and a pressing head installed at the output end of the pressing cylinder; the pushing seat has an abutment portion, and the pressing head has a pressing portion facing the abutment portion;

[0013] The two ends of the guide strip are fixed to two support bases respectively, and the guide strip has a guide groove extending through it along its length. The pressing head presses the rubber sleeve against the abutment part through the guide groove and moves downward along the guide groove under the drive of the drive motor.

[0014] By adopting the above technical solution, the pushing mechanism and the guide bar work together to push the rubber sleeve. The pressing part can press the rubber sleeve against the abutting part through the guide groove and drive the rubber sleeve downward along the guide groove after pressing. During this process, the guide groove of the guide bar can ensure that the rubber sleeve can be pushed smoothly, and at the same time limit the pushing path of the pushing mechanism to ensure that the rubber sleeve pushing process is smooth.

[0015] Optionally, the cutting mechanism includes a cutting cylinder mounted on a lower support, a cutting seat connected to the output end of the cutting cylinder and moving horizontally under the drive of the cutting cylinder, and a cutting blade mounted on the cutting seat; the lower support has a cutting groove for the cutting blade to be inserted, and the guide bar has a clearance that is opposite to the cutting groove and allows the cutting blade to pass through.

[0016] By adopting the above technical solution, when the cutting mechanism cuts the rubber sleeve, the cutting blade can be inserted into the cutting groove through the clearance, thereby cutting the rubber sleeve more quickly and reducing the possibility of root coupling when the rubber sleeve is cut.

[0017] Optionally, the bracket is provided with a lubrication spraying mechanism, which includes an oil reservoir, an oil pump, and spray heads disposed at the upper and lower ends of the guide strip.

[0018] By adopting the above technical solution, during the pushing process, the end of the rubber sleeve is sprayed with liquid by a spraying mechanism, making the movement of the rubber sleeve on the clamp smoother. Simultaneously, lubricating oil is sprayed between the rubber sleeve and the guide strip to reduce friction between them.

[0019] Optionally, the mounting base mechanism includes a mounting platform, a screw drive assembly that drives the mounting platform to make horizontal displacement on the worktable, and a positioning seat mounted on the mounting platform; the mounting platform is provided with positioning holes spaced apart for selective installation of the positioning seat to accommodate clamps of different sizes.

[0020] Secondly, this application provides a method for applying a clamping adhesive, which adopts the following technical solution:

[0021] A method for applying a clamp to a device includes:

[0022] Step 1: Adjust the position of the positioning seat before the equipment is running, and capture the position image of the positioning seat while the equipment is running;

[0023] Step 2: Identify and analyze the positioning image of the positioning seat to determine product information;

[0024] Step 3: Match the push length of the adhesive sleeve based on the product information;

[0025] Step 4: Control the support opening of the rubber sleeve with the preset reference opening amount and control the pushing mechanism to push the rubber sleeve with the rubber sleeve pushing length.

[0026] Step 5: After the push is completed, control the cutting mechanism to cut off the rubber sleeve, and control the pushing mechanism to push the new rubber sleeve with a preset pre-push length so that the cut end of the rubber sleeve is pushed into the clamp.

[0027] By adopting the above technical solution, after the rubber sleeve is cut by the cutting mechanism, the pushing mechanism will continue to push the new rubber sleeve a certain distance, thereby further advancing the old rubber sleeve through the new rubber sleeve, so that the tail of the cut rubber sleeve can smoothly enter the clamp, reducing the steps of manual adjustment of the rubber sleeve, thereby improving the rubber sleeve efficiency.

[0028] Optional, also includes:

[0029] Step 400: Identify the clamp placement features from the positioning seat position image;

[0030] Step 401: Set the intermediate baseline, and determine the single-sided offset based on the hoop placement characteristics and the intermediate baseline;

[0031] Step 402: Match the offset degree type based on the comparison between twice the unilateral offset and the preset offset threshold. The offset degree type includes small offset and large offset.

[0032] Step 40200: In the case of a small offset, determine the bilateral expansion amount based on the single-sided offset amount;

[0033] Step 40201: Replace the baseline expansion amount with the double-sided expansion amount, and control the expansion opening of the rubber sleeve opening with the double-sided expansion amount.

[0034] By adopting the above technical solution, when there is a small offset during the installation of the clamp, the support opening is adjusted so that the groove of the rubber sleeve is enlarged to meet the position requirements of the clamp after the offset. This allows the rubber sleeve to be quickly fitted into the clamp without adding extra rubber fitting steps, thus eliminating the risk of offset during clamp installation.

[0035] Optionally, control methods for situations with large offsets include:

[0036] Step 40210: In the case of large offset, determine the bilateral expansion amount based on the unilateral offset amount;

[0037] Step 40211: When the double-sided opening amount exceeds the preset maximum opening amount of the opening, an alarm is issued and the machine is stopped after a preset buffer waiting time;

[0038] Step 40212: When the double-sided opening amount is not greater than the maximum opening amount of the opening, replace the reference opening amount with the maximum opening amount of the opening. Before the clamp moves from the feeding station to the rubber fitting station, control the opening with the maximum opening amount of the opening.

[0039] Step 40213: When the clamp is located at the rubber sleeve station, control the support opening to adjust from the maximum opening amount to the reference opening amount so as to clamp on both sides of the clamp and correct the clamp.

[0040] By adopting the above technical solution, when there is a large offset in the installation of the clamp, the position of the clamp is corrected by opening the support opening to the maximum extent and moving it inward from both sides of the clamp, so that the clamp can be aligned with the middle reference line, thus facilitating the quick insertion of the rubber sleeve.

[0041] Optional methods for handling jamming during the rubber application process include:

[0042] Step 410: During each round of rubber pushing, record the real-time descent distance of the pusher seat and collect infrared signals in real time;

[0043] Step 411: When there is no infrared signal, define the rubber sleeve jamming and lifting, and identify the feed position of the rubber sleeve end from the positioning seat position image;

[0044] Step 412: Determine the feed distance of the rubber sleeve by combining the feed position of the rubber sleeve end and the product information;

[0045] Step 413: Calculate the rubber sleeve warping recovery distance based on the real-time descent distance and the rubber sleeve feed distance;

[0046] Step 414: Control the pushing mechanism to move the rubber sleeve upwards and reset it by adjusting the rubber sleeve lifting and restoring distance;

[0047] Step 415: Generate a reciprocating insertion scheme based on the rubber sleeve feed distance;

[0048] Step 416: After completing the upward reset, control the pushing mechanism to drive the rubber sleeve to apply the rubber according to the reciprocating insertion scheme.

[0049] By adopting the above technical solution, when the rubber sleeve gets stuck and lifts up, the lifting situation of the rubber sleeve is processed first by calculation, so that the rubber sleeve can be evenly stressed during the subsequent pushing process. Then, the rubber sleeve is processed by a reciprocating traction-type reciprocating movement insertion scheme, thereby solving the problem of easy jamming during the rubber sleeve pushing process without the need for manual processing of the rubber sleeve, thus improving the rubber sleeve application efficiency.

[0050] Optionally, methods for generating reciprocating insertion schemes include:

[0051] Step 4150: Calculate the remaining sleeve distance based on the sleeve push length and sleeve feed distance;

[0052] Step 4151: Divide the remaining rubber distance into multiple segments according to the preset step spacing;

[0053] Step 4152: Define the backward movement distance as the back distance, and define the forward movement distance as the sum of the back distance and the step spacing;

[0054] Step 4153: After completing the upward reset, the rubber sleeve is moved back according to the retraction distance. During the retraction process, the preset spraying mechanism controls the preset spraying amount and oil temperature to spray lubricating oil into the rubber sleeve.

[0055] Step 4154: After completing the retraction, move the rubber sleeve forward according to the forward distance and check whether there is an infrared signal;

[0056] Step 4155: If an infrared signal is present, continue to move the rubber sleeve forward for further application.

[0057] Step 4156: If there is no infrared signal, repeat steps 4153 and 4154 in sequence.

[0058] By adopting the above technical solution, a reciprocating pushing method combined with lubrication is used to process the rubber sleeve when it gets stuck. This allows the rubber sleeve to pass the stuck point quickly without manual intervention, thereby completing the rubber sleeve process and improving rubber sleeve efficiency.

[0059] In summary, this application includes at least one of the following beneficial technical effects:

[0060] 1. By using mechanical automation to apply rubber to clamps, except for the manual installation and feeding of clamps, the rest of the rubber application process can be automated, which greatly improves the efficiency of clamp rubber application.

[0061] 2. During the pushing process, the rubber sleeve is sprayed with lubricating oil at the end of the rubber sleeve and between the rubber sleeve and the guide strip through the spraying mechanism to reduce friction during the pushing process and reduce the risk of jamming.

[0062] 3. After the rubber sleeve is cut by the cutting mechanism, the pushing mechanism will continue to push the new rubber sleeve a certain distance, thereby further advancing the old rubber sleeve through the new rubber sleeve, so that the tail of the cut rubber sleeve can smoothly enter the clamp, reducing the steps of manual adjustment of the rubber sleeve, thereby improving the rubber sleeve application efficiency.

[0070] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be 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 illustrative and not intended to limit the invention.

[0071] This application discloses a clamping and rubber-coating device.

[0072] Reference Figure 1 The clamp fitting equipment includes a workbench 1, an installation base mechanism 2, a guiding mechanism 3, a pushing mechanism 4, a cutting mechanism 5, and a spraying mechanism 6. The workbench 1 serves as the base of the entire equipment, providing support. The installation base mechanism 2 is used for installing the clamps. The guiding mechanism 3 is used for installing the rubber sleeve and guiding its movement. The pushing mechanism 4 is used to move the rubber sleeve to fit onto the clamp. The cutting mechanism 5 is used to cut the rubber sleeve after it has been fitted. The spraying mechanism 6 is used to spray lubricating oil onto the rubber sleeve to reduce the risk of jamming during the clamp fitting process.

[0073] Reference Figure 1 and Figure 2 The pushing mechanism 4 includes a bracket 41, a support base 42, a drive screw 43, a drive motor 44, a pushing seat 45, and a pushing assembly 46. The pushing assembly 46 further includes a pressing cylinder 461 and a pressing head 462.

[0074] The bracket 41 is fixedly mounted on the worktable 1. Two support seats 42 are fixedly mounted on the upper and lower sides of the bracket 41, respectively. A drive screw 43 vertically passes through both support seats 42 and can rotate on them. A drive motor 44 is mounted on the top of the upper support seat 42 and is connected to the drive screw 43 via a coupling. The drive motor 44 drives the drive screw 43 to rotate. A pusher seat 45 is threaded onto the drive screw 43 and is circumferentially limited by the bracket 41 to prevent circumferential rotation. When the drive screw 43 rotates, the pusher seat 45 can vertically rise and fall along the drive screw 43.

[0075] The clamping cylinder 461 is fixedly mounted on the pusher seat 45 and can rise and fall synchronously with the pusher seat 45. The clamping head 462 is fixedly mounted on the output end of the clamping cylinder 461.

[0076] Reference Figure 2 and Figure 3In this embodiment, the rubber sleeve passes vertically downward between the pusher seat 45 and the clamping head 462. Therefore, the pusher seat 45 has an abutment portion 463 on the side facing the clamping head 462, and the clamping head 462 has a clamping portion 464 directly opposite the abutment portion 463. When the clamping cylinder 461 retracts, the clamping portion 464 can press the rubber sleeve against the abutment portion 463 of the pusher seat 45. When the pusher seat 45 moves vertically downward, the rubber sleeve can be pulled and moved.

[0077] After the pusher seat 45 completes the push according to the set descent distance, the clamping cylinder 461 pushes the clamping head 462 outward to loosen the rubber sleeve. At this time, the pusher seat 45 is reset upward to perform the next round of rubber sleeve operation.

[0078] Reference Figure 1 , Figure 2 and Figure 3 The guiding mechanism 3 includes a guiding conveyor belt 31, a guiding strip 32, and a support part 33.

[0079] The guide conveyor belt 31 is horizontally mounted on top of the upper support 42, and has multiple conveying rollers on it. The guide bar 32 is a long metal strip, which is vertically arranged and fixed at both ends to the upper and lower support 42 respectively. At the same time, the guide bar 32 passes vertically downward between the pusher seat 45 and the pressing head 462.

[0080] The rubber sleeve enters from one end of the guide conveyor belt 31 and exits from the other end. After being bent at a 90-degree angle, it is fitted onto the guide bar 32, which is then snapped into a groove in the rubber sleeve. A guide groove 34 is formed along the length of the guide bar 32. The pressing head 462 presses the rubber sleeve against the abutment part 463 through the guide groove 34, and the rubber sleeve moves downward along the guide bar 32 under the drive of the drive motor 44.

[0081] Here, the guide bar 32 can be used to guide the direction of movement, and the guide groove 34 can also be used for travel limit.

[0082] The support portion 33 is installed at the bottom of the guide strip 32 and has two support claws with adjustable opening angles. When the rubber sleeve moves along the guide strip 32 to the bottom end, the support portion 33 opens the opening of the rubber sleeve, making it easy for the rubber sleeve to be fitted onto the clamp.

[0083] Reference Figure 1 and Figure 4 The cutting mechanism 5 includes a cutting cylinder 51 and a cutting blade 52.

[0084] The cutting cylinder 51 is fixedly mounted on the support base 42 on the lower side, and the cutting blade 52 is mounted on the output end of the cutting cylinder 51. The cutting cylinder 51 can drive the cutting blade 52 to move horizontally.

[0085] Both the guide strip 32 and the rubber sleeve pass vertically downward between the lower support 42 and the cutting blade 52. The lower support 42 has a cutting groove 421 for the cutting blade 52 to be inserted. The guide strip 32 has a clearance that is directly opposite to the cutting groove 421 and allows the cutting blade 52 to pass through. The clearance divides the guide strip 32 into two parts.

[0086] When the cutting cylinder 51 retracts, it drives the cutting blade 52 to insert into the cutting groove 421 through the clearance. During this process, the cutting blade 52 cuts off the rubber sleeve.

[0087] Reference Figure 1 and Figure 5 The mounting base mechanism 2 includes a mounting platform 21, a screw drive assembly 22, and a positioning base 23.

[0088] The mounting platform 21 is slidably mounted on the worktable 1 via the screw drive assembly 22. The screw drive assembly 22 is a conventional structure in the prior art, that is, a motor drives the screw to rotate, and the mounting platform 21 is mounted on the screw and can move horizontally on the screw.

[0089] The mounting platform 21 has multiple positioning holes 24 spaced apart, and the positioning seat 23 is mounted on the mounting platform 21 through the positioning holes 24. The positioning seat 23 is used for clamp installation. In order to adapt to clamps of different sizes, the positioning seat 23 can be fixed by selecting different positions of the positioning holes 24. The positioning seat 23 has a magnetic seat 25, which can attract the clamp and prevent the clamp from falling off the positioning seat 23 when applying rubber.

[0090] Driven by the screw drive assembly 22, the mounting table 21 has a loading station and a fitting station on the worktable 1, and the mounting table 21 can reciprocate and switch between the two stations. The loading station is used to install the clamp on the positioning seat 23, and the loading station is away from the pushing mechanism 4. The fitting station is used for fitting. When the clamp is in the fitting station, one end of the clamp is directly opposite the bottom end of the guide strip 32, and the rubber sleeve enters directly from one end of the clamp after passing through the opening of the support part 33.

[0091] Reference Figure 1 and Figure 6 The spraying mechanism 6 includes an oil reservoir 61, an oil pump 62, and a spray head 63. The oil reservoir 61 is mounted on the back of the bracket 41 of the pushing mechanism 4 and is used to store lubricating oil. The spray head 63 is mounted on the upper and lower ends of the guide strip 32. The oil pump 62 connects the oil reservoir 61 and the spray head 63 and is used to deliver lubricating oil from the oil reservoir 61 into the spray head 63 and spray it onto the inner wall of the rubber sleeve.

[0092] The lower spray head 63 can spray lubricating oil onto the end of the rubber sleeve, making the rubber sleeve fit into the clamp more smoothly. The upper spray head 63 can spray liquid when the rubber sleeve moves, so that the rubber sleeve can move smoothly on the guide strip 32 without jamming, and pre-lubricates the inside of the rubber sleeve.

[0093] Based on the same inventive concept, embodiments of the present invention provide a method for applying adhesive to clamps.

[0094] A method for applying adhesive to a clamp includes the following steps:

[0095] Step 1: Adjust the position of the positioning seat 23 before the equipment is running, and capture the position image of the positioning seat while the equipment is running.

[0096] The position adjustment of the positioning seat 23 here refers to adjusting the installation position of the positioning seat 23 on the mounting platform 21 according to the size of the clamp, so that the positioning seat 23 fits the size of the clamp. This step is performed manually and is done before the equipment starts running; it is an initialization action.

[0097] Since the installation of the positioning seat 23 is a manual operation, the system needs to perform image recognition on the position of the positioning seat 23 after installation to determine its location. The positioning seat position image is obtained by taking a picture of the positioning seat 23 on the mounting platform 21 using a camera installed on the equipment. The position of the positioning seat 23 can be identified from the image.

[0098] Step 2: Identify and analyze the positioning image of the positioning seat to determine product information.

[0099] The product information refers to the dimensions of the clamp to be fitted with rubber. By identifying the positioning seats 23 from the positioning seat position image, the positions of the two positioning seats 23 and the distance between them are determined, and the product information is matched based on these conditions. Different distances between the two positioning seats 23 allow for the installation of clamps of different sizes.

[0100] Step 3: Match the push length of the rubber sleeve based on the product information.

[0101] The sleeve push length refers to the length of the sleeve that needs to be fitted onto the clamp. The sleeve push length can be obtained by matching product information into a preset system parameter database. This database stores the correspondence between different clamp sizes and their corresponding sleeve lengths, and is pre-entered into the system by technicians.

[0102] Step 4: Control the support opening 33 to support the rubber sleeve opening with the preset reference opening amount and control the pushing mechanism 4 to push the rubber sleeve with the rubber sleeve pushing length.

[0103] The reference opening amount is the amount by which the support portion 33 expands the rubber sleeve when it is fitted into the clamp. This parameter is obtained by technicians through prior testing and measurement. When the clamp is properly positioned on the positioning seat 23, the rubber sleeve is opened according to the reference opening amount, and the rubber sleeve can just fit into the clamp.

[0104] With the clamp positioned correctly, the system sets the support portion 33 according to the reference opening parameter value, causing the support portion 33 to open the rubber sleeve. Then, after the rubber sleeve is opened, the system pushes the rubber sleeve according to the pushing length, allowing the rubber sleeve to fit onto the clamp.

[0105] The solutions for handling the effects of improper clamp placement and the solutions for handling the jamming problem caused by improper placement during the rubber application process will not be elaborated here, but will be described in detail in subsequent embodiments.

[0106] Step 5: After the push is completed, control the cutting mechanism 5 to cut off the rubber sleeve, and control the pushing mechanism 4 to push the new rubber sleeve with a preset pre-push length so that the cut end of the rubber sleeve is pushed into the clamp.

[0107] After the pushing mechanism 4 pushes the rubber sleeve according to the specified pushing length, the system controls the cutting mechanism 5 to cut the rubber sleeve. The length of the cut rubber sleeve is just right to match the clamp. However, due to the distance between the cutting mechanism 5 and the clamp, the tail of the rubber sleeve does not completely enter the clamp after being cut. At this time, the system controls the pushing mechanism 4 to push the new uncut part of the rubber sleeve according to the pre-pushed length, so that the new rubber sleeve can move against the old cut rubber sleeve, thereby pushing the tail of the cut rubber sleeve into the clamp, completing one basic rubber sleeve application operation.

[0108] The pre-push length is the distance between the cutting mechanism 5 and the end of the clamp, which is set by technicians according to the actual size parameters of the equipment.

[0109] The method for controlling the misalignment of the clamping part 33 includes the following steps:

[0110] Step 400: Identify the clamp placement features from the positioning seat position image.

[0111] The clamp placement feature refers to the positional characteristics of the clamp when it is installed on the positioning seat 23. The two vertices of the clamp closest to the pushing mechanism 4 are used as the positional characteristics of the clamp. The clamp placement feature is determined by identifying the positions of the two vertices of the clamp from the positioning seat position image, using the reference point on the positioning seat 23 as a reference point.

[0112] Step 401: Set the intermediate baseline, and determine the single-sided offset by combining the hoop placement characteristics and the intermediate baseline.

[0113] The intermediate baseline is the center line when the clamp is normally placed. It serves as a reference baseline for determining whether the clamp has shifted. The intermediate baseline is preset by the technicians.

[0114] The single-sided offset refers to the offset distance between the actual placement position of the clamp and the center baseline.

[0115] The system sets a midline in the image recognition interface, compares the recognized hoop placement features with the midline, and calculates the actual distance the hoop shifts to one side.

[0116] Step 402: Match the offset degree type based on the comparison between twice the unilateral offset and the preset offset threshold. The offset degree type includes small offset and large offset.

[0117] The offset threshold is the critical value set by the technician for the degree of clamp offset, which is the maximum width that the rubber sleeve can be stretched.

[0118] When twice the unilateral offset is less than the offset threshold, it indicates that the clamp offset is small, belonging to the small offset category. When twice the unilateral offset is not less than the offset threshold, it indicates that the clamp offset is large, belonging to the large offset category.

[0119] The system will use different processing methods for the two types of offset.

[0120] Step 40200: In the case of a small offset, determine the double-sided expansion amount based on the single-sided offset amount.

[0121] For minor offsets, the rubber sleeve may still fit into the clamp even after being stretched. Since the rubber sleeve is symmetrically set along the central baseline, it needs to be stretched by twice the offset of the clamp. The bilateral stretch is twice the offset of the clamp, which is twice the value of the single-sided offset.

[0122] Step 40201: Replace the baseline expansion amount with the bilateral expansion amount, and control the rubber sleeve expansion of the expansion part 33 with the bilateral expansion amount.

[0123] The system replaces the original preset baseline opening amount with a new double-sided opening amount, controls the two support claws of the support opening 33 to adjust the opening angle according to the double-sided opening amount, symmetrically opens the rubber sleeve slot, adapts to the small offset placement state of the clamp, and then performs the subsequent rubber sleeve pushing operation.

[0124] The control methods for the support portion 33 in the case of large offset include:

[0125] Step 40210: In the case of large offset, determine the bilateral expansion amount based on the single-sided offset amount.

[0126] Similar to step 40200, it will not be repeated here. In this embodiment, since the clamp offset is too large, the method of spreading the rubber sleeve is not suitable. Here, it is necessary to adjust the position of the clamp through the support portion 33. Since the two support claws of the support portion 33 are symmetrically arranged, by opening the two support claws and moving them closer to the offset clamp from both sides, the clamp is driven to move and adjust towards the central reference line.

[0127] Compared to the normal rubber application process, an additional step of adjusting the clamps is added at this stage. Adjusting the clamps also requires determining the bilateral spread, which is twice the value of the unilateral offset.

[0128] Step 40211: When the bilateral expansion amount exceeds the preset maximum expansion amount of the support opening, an alarm is issued and the machine is stopped after a preset buffer waiting time.

[0129] The maximum opening amount of the support part is the maximum working opening size of the support part 33 preset by the technicians based on the structural strength of the support part 33, which is the critical value for safe operation of the support part 33.

[0130] If the double-sided opening exceeds the maximum opening of the support opening, the support opening 33 will also be unable to handle the clamp. In this case, the system will stop pushing the rubber sleeve and issue an alarm.

[0131] The buffer waiting time is the time set by the technicians for the operators to make adjustments to the equipment.

[0132] If the operator fails to adjust the position of the clamp within the buffer waiting time, the equipment will be shut down.

[0133] Step 40212: When the double-sided expansion amount is not greater than the maximum expansion amount of the expansion opening, the reference expansion amount is replaced with the maximum expansion amount of the expansion opening. Before the clamp moves from the feeding station to the rubber fitting station, the maximum expansion amount of the expansion opening is used to control the expansion opening 33.

[0134] If the bilateral expansion amount is not greater than the maximum expansion amount of the support opening, the system will replace the reference expansion amount with the maximum expansion amount of the support opening. Before the screw drive assembly 22 drives the mounting table 21 to move the clamp from the feeding station to the rubber fitting station, the system controls the support opening 33 to open the two support claws of the support opening 33 to the maximum state with the maximum expansion amount of the support opening.

[0135] Step 40213: When the clamp is located at the rubber sleeve station, control the support part 33 to adjust from the maximum opening amount of the support part to the reference opening amount so as to clamp on both sides of the clamp and correct the clamp.

[0136] When the mounting platform 21 moves the clamp to the rubber sleeve position, with one end of the clamp aligned with the bottom end of the guide strip 32, the system controls the support portion 33 to slowly adjust from the maximum opening to the double-sided opening. The two support claws of the support portion 33 clamp the clamp on both sides and move relatively close to the reference opening, using the support claws to correct the clamp so that it fits the normal placement position as closely as possible. After completing the above adjustment steps, the rubber sleeve pushing operation is then performed.

[0137] The following steps are included in handling jamming during the rubber application process:

[0138] Step 410: During each round of rubber pushing, record the real-time descent distance of the pusher 45 and collect infrared signals in real time.

[0139] The real-time descent distance is the actual vertical downward movement of the pusher seat 45 during the rubber sleeve pushing process, which is recorded in real time by the equipment's displacement sensor.

[0140] The infrared signal is generated by the infrared sensor when the rubber sleeve is pushed normally, and it is the key basis for determining whether the rubber sleeve is stuck or warped. The infrared sensor includes a transmitter and a receiver. The transmitter is located at the upper end of the guide strip 32, and the receiver is located at the lower end of the guide strip 32. When the rubber sleeve is pushed normally without warping, the infrared light emitted by the transmitter can be received by the receiver, thus generating an infrared signal. When the propagation path of the infrared light is interrupted by the warped part of the rubber sleeve, no infrared signal is generated.

[0141] During the process of pushing the rubber sleeve, the equipment control system records the vertical downward movement distance of the pusher seat 45 in real time, and at the same time collects infrared signals in real time through the infrared sensor on the equipment.

[0142] Step 411: When there is no infrared signal, define the rubber sleeve jamming and lifting, and identify the feed position of the rubber sleeve end from the positioning seat position image.

[0143] The feed position of the rubber sleeve end refers to the actual position of the rubber sleeve end as it is pushed to the clamp when the rubber sleeve jams and lifts. The feed position of the rubber sleeve end can be obtained by identifying the features of the rubber sleeve end from the positioning seat position image using an image recognition system.

[0144] If the infrared sensor can collect infrared signals, it means that the device is operating normally and the system continues to collect infrared signals.

[0145] If the infrared sensor fails to detect an infrared signal, the system determines that the rubber sleeve has jammed and warped. The system then analyzes the positioning image of the positioning seat to determine the feed position of the rubber sleeve end.

[0146] Step 412: Determine the feed distance of the rubber sleeve by combining the feed position of the rubber sleeve end and the product information.

[0147] The rubber sleeve feed distance refers to the effective distance the rubber sleeve actually advances on the clamp when it jams and tilts. When the rubber sleeve jams, the feed distance is usually less than the real-time descent distance of the pusher seat 45.

[0148] The system combines the identified feed position of the rubber sleeve end with the matched product information to calculate the effective distance the rubber sleeve actually advances. From the product information, the system can determine the movement path of the rubber sleeve and the actual distance from each point on the movement path to the end of the clamp.

[0149] Step 413: Calculate the rubber sleeve lifting and recovery distance based on the real-time descent distance and the rubber sleeve feed distance.

[0150] The sleeve warping recovery distance refers to the upward movement of the pusher seat 45 required to reset the warped sleeve and remove it from the warped state. The sleeve warping recovery distance is the difference between the real-time descent distance and the sleeve feed distance.

[0151] Step 414: The push mechanism 4 is driven by the rubber sleeve to move upward and reset by controlling the distance of the rubber sleeve lifting and restoring.

[0152] The drive motor 44 of the system control pushing mechanism 4 rotates in reverse, driving the pushing seat 45 to move upwards by the rubber sleeve's warping recovery distance, causing the jammed rubber sleeve to reset upwards and disengage from the warped state. After the rubber sleeve disengages from the warped state, the end of the rubber sleeve is still jammed with the clamp, requiring further processing.

[0153] Step 415: Generate a reciprocating insertion scheme based on the rubber sleeve feed distance.

[0154] The reciprocating insertion scheme refers to a pushing mechanism used by the equipment to smoothly insert the rubber sleeve into the clamp via a reciprocating back-forward motion, addressing the problem of rubber sleeve jamming. The reciprocating insertion scheme is generated based on the rubber sleeve feed distance; the specific generation method will not be detailed here but will be described in detail in subsequent embodiments.

[0155] Step 416: After completing the upward reset, control the pushing mechanism 4 to drive the rubber sleeve to apply the rubber according to the reciprocating insertion scheme.

[0156] After the rubber sleeve completes its upward reset, the system controls the pushing mechanism 4 to reciprocate and push the rubber sleeve in a reciprocating manner according to the generated reciprocating insertion scheme until the rubber sleeve is successfully fitted into the clamp.

[0157] The method for generating a reciprocating insertion scheme includes the following steps:

[0158] Step 4150: Calculate the remaining sleeve distance based on the sleeve push length and sleeve feed distance.

[0159] The remaining rubber sleeve distance refers to the remaining distance that the rubber sleeve needs to be pushed to complete the rubber sleeve application after it has been lifted and reset. The remaining rubber sleeve distance is the difference between the rubber sleeve pushing length and the rubber sleeve feed distance.

[0160] Step 4151: Divide the remaining rubber distance into multiple segments using a preset step spacing.

[0161] The step spacing is the base distance preset by the technicians to divide the remaining rubber distance into segments.

[0162] In this embodiment, in order to adjust the rubber sleeve by reciprocating movement, the system divides the calculated remaining rubber sleeve distance into multiple segments according to the step spacing.

[0163] Step 4152: Define the backward movement distance as the back distance, and define the forward movement distance as the sum of the back distance and the step spacing.

[0164] The retraction distance is the fixed distance the rubber sleeve travels backward during its reciprocating movement. The forward distance is the distance the rubber sleeve advances during its reciprocating movement, and is the sum of the retraction distance and the step distance. The forward distance is greater than the retraction distance, thus achieving the purpose of small-step forward movement and multiple pushes.

[0165] Step 4153: After completing the upward reset, the rubber sleeve is moved back according to the retraction distance. During the retraction process, the preset spraying mechanism 6 sprays lubricating oil into the rubber sleeve according to the preset spraying volume and oil temperature.

[0166] The spray volume refers to the fixed amount of lubricating oil sprayed onto the inner wall of the 6-way rubber sleeve of the spray mechanism, which is preset by technicians according to the lubrication requirements of the rubber sleeve.

[0167] The oil temperature refers to the preset temperature of the lubricating oil sprayed by the spraying mechanism 6. The spraying mechanism 6 is equipped with a heating module, which can heat the lubricating oil in the oil storage tank 61.

[0168] After the rubber sleeve completes its upward reset, the system controls the pushing mechanism 4 to move the rubber sleeve backward a preset distance. During the retraction process, the spraying mechanism 6 controls the spraying head 63 at the lower end of the guide strip 32 to spray lubricating oil onto the inner wall of the rubber sleeve according to the spray volume and oil temperature. The lubricating oil reduces the friction between the rubber sleeve and the clamp, and the lubricating oil at a suitable temperature can heat the rubber sleeve, making it easier to open.

[0169] Step 4154: After completing the retraction, move the rubber sleeve forward according to the forward distance and check whether there is an infrared signal.

[0170] After the rubber sleeve completes its retraction, the system controls the pushing mechanism 4 to propel the rubber sleeve forward a calculated distance, thus completing one reciprocating motion. During this forward propulsion, infrared obstruction signals are collected in real time to determine whether the rubber sleeve is being pushed forward correctly.

[0171] Step 4155: If an infrared signal is present, continue to move the rubber sleeve forward to apply the rubber.

[0172] If infrared signals can be continuously collected, it indicates that the rubber sleeve is being pushed normally. The system will continue to control the rubber sleeve to advance and apply the rubber sleeve according to the forward distance until the remaining rubber sleeve distance is completed.

[0173] Step 4156: If there is no infrared signal, repeat steps 4153 and 4154 in sequence.

[0174] If no infrared signal is collected after advancing forward, it indicates that the rubber sleeve still has a risk of jamming. The system then re-controls the rubber sleeve to perform the retraction spraying in step 4153 and the forward pushing in step 4154 until an infrared signal is collected and the rubber sleeve is pushed forward normally.
