Description

Technical Field

[0003] like Figure 1 The product 1 shown includes a product body 101 and a tube body 102. The tube body 102 runs through the product body 101. The tube body 102 has a channel 103 for the waterproof rubber sleeve to pass through. When a rubber sleeve of a specific length is inserted into the above product, a thin-walled auxiliary tube 104 is generally inserted into the tube body 102 to reduce the resistance of inserting the rubber sleeve, and the limiting end 105 of the auxiliary tube 104 has a larger diameter for easy removal. For the rubber sleeve of this product, the traditional method of inserting the rubber sleeve is to manually insert the rubber sleeve and remove the auxiliary tube.

[0021] The present invention discloses a mechanism for pre-threading waterproof rubber sleeves for automobile wiring harnesses. The first clamping assembly of the rubber sleeve threading mechanism is in an open state near the starting end of the guide assembly, ready to clamp the rubber sleeves. The second clamping assembly and the third clamping assembly of the tube removal mechanism are both in an open state. The material removal plate is located at an initial position away from the second side of the limiting assembly. The feeding assembly of the feeding mechanism takes out the product to be threaded from the storage assembly and conveys it to the limiting assembly. When the product to be threaded reaches the limiting component, the limited component is limited along the first direction and stops moving. The first clamping component of the rubber sleeve threading mechanism moves to the starting end of the guide component under the drive of the first driving component, clamps the end of the rubber sleeve to be threaded, and uses the first clamping component to move toward the first side of the limiting component along the first direction under the drive of the first driving component to introduce the rubber sleeve into the guide space of the guide component. The rubber sleeve moves along the guide space toward the limiting component. The first clamping component clamps the rubber sleeve on the first side of the limiting component and continues to move along the first direction, passing the rubber sleeve through the auxiliary pipe to reach the second side of the limiting component, and clamps the rubber sleeve again and moves along the first direction to the third clamping component. The third clamping component closes when the rubber sleeve reaches its position and clamps the rubber sleeve. The first clamping component opens to complete the threading action of the rubber sleeve.

[0022] The second clamping assembly of the tube removal mechanism moves to the vicinity of the rubber sleeve under the drive of the second driving assembly, and clamps the rubber sleeve on the first side of the limiting assembly. The third driving member drives the material removal plate to make its limiting groove clamped on the end of the auxiliary tube. The material removal plate moves under the drive of the third driving assembly, so that the limiting groove clamps the end of the auxiliary tube, and moves along the first direction to approach the third clamping assembly, detaching from the product to be worn, and the first clamping assembly is used again to clamp the auxiliary tube to the third clamping assembly, and the third clamping assembly is used to clamp the auxiliary tube, and the first clamping assembly is used to clamp the rubber sleeve, and the fifth clamping assembly is used to clamp the auxiliary tube, and the auxiliary tube is removed. The fifth driving assembly drives the fifth clamping assembly to move the auxiliary tube to the receiving bin for recycling.

[0023] The limiting assembly includes: a positioning seat, a positioning rod, a first cylinder, a crimping piece and a second cylinder. The positioning rod is connected to the first cylinder to move in the first direction. The end of the positioning rod is provided with a second limiting groove adapted to the second side of the product to be pierced. The positioning seat is adapted to the product to be pierced. The crimping piece and the first cylinder and the second cylinder are connected to move in the third direction. The crimping piece and the positioning seat are surrounded by a guide hole adapted to the tube body to be pierced. The guide hole corresponds to the auxiliary tube, and the product to be pierced is placed on the positioning seat. Then, the first cylinder is started to drive the positioning rod to move in the first direction. The second limiting groove at the end of the positioning rod gradually approaches the second side of the product to be pierced until it is accurately inserted. At this time, the product to be pierced is limited by the positioning seat and the positioning rod in the first direction. The second cylinder moves in the third direction according to the driving crimping piece. During the process of inserting the rubber sleeve or the auxiliary tube, the positioning seat and the positioning rod always maintain a limiting state for the product to be pierced to prevent the product from moving.

[0024] Reference Figure 8As shown, the guide assembly includes: a first limit plate, a second limit plate, a third cylinder, a first limit rod, a second limit rod and a fourth cylinder, the second limit plates are respectively arranged on both sides of the first limit plate along the second direction, each of the second limit plates is connected to the third cylinder to adjust the distance from the first limit plate, the first limit plate and the second limit plate are both provided with a first through hole and a second through hole, the first through hole and the second through hole are respectively arranged along the third direction, the first limit rod is fixedly penetrated through the first limit plate, the second limit rod is connected to the fourth cylinder and can be movably penetrated through the second through hole along the second direction, the rubber sleeve to be penetrated is penetrated between the first limit rod and the second limit rod, the third cylinder and the fourth cylinder are adjusted to form an initial space adapted to the size of the rubber sleeve between the first limit plate, the second limit plate, the first limit rod and the second limit rod. The rubber sleeve to be inserted is placed in the space between the first limiting rod and the second limiting rod, with one end of the rubber sleeve close to the first clamping assembly of the rubber sleeve inserting mechanism for subsequent insertion operations. When the first clamping assembly of the rubber sleeve inserting mechanism starts to move the rubber sleeve along the first direction, the rubber sleeve moves in the guide space between the first limiting rod and the second limiting rod. Due to the limiting effect of the first limiting plate and the second limiting plate, and the guiding effect of the first limiting rod and the second limiting rod, the rubber sleeve moves along a predetermined path toward the limiting assembly to prevent movement.

[0025] Reference Fig.11As shown, the first drive assembly is the first three-axis drive assembly, and the fifth drive assembly is the fifth three-axis drive assembly. The three-axis drive mechanisms in this embodiment can move independently along the first direction, the second direction and the third direction. The first clamping assembly includes: an intermediate plate, a first clamping cylinder, and a clamping plate. The size of the intermediate plate is adapted to the spacing between the two groups of rubber sleeves to be inserted. The clamping plate is connected to the clamping cylinder. The clamping plates are movably arranged on both sides of the intermediate plate. When the rubber sleeve insertion device does not start working, the first three-axis drive assembly positions the first clamping assembly at the initial position, which is usually close to the rubber sleeve starting position of the guide assembly. The first clamping cylinder is in the initial state, the piston is retracted, and the clamping plates on both sides are in the open state. The intermediate plate is located between the two groups of rubber sleeves to be inserted or in a suitable position according to the situation of the insertion of a single group of rubber sleeves. When it is necessary to clamp the rubber sleeve or the auxiliary pipe, compressed air is introduced into the air inlet of the first clamping cylinder, and the piston extends to drive the clamping plates on both sides to approach the intermediate plate. The inner side of the clamping plate contacts and gradually clamps the rubber sleeve or the auxiliary tube end, firmly clamping the rubber sleeve or the auxiliary tube, and the first clamping assembly starts to move under the drive of the first three-axis drive assembly. According to the instructions of the control system, the motors in the three directions of the first three-axis drive assembly work together to move the first clamping assembly along a predetermined path, and the first clamping assembly starts to move under the drive of the first three-axis drive assembly. According to the instructions of the control system, the motors in the three directions of the first three-axis drive assembly work together to move the first clamping assembly along a predetermined path.

[0026] Reference Fig.10 As shown, the second driving assembly is a second three-axis driving assembly, and the second clamping assembly includes: a second clamping cylinder and a second clamping arm. The second clamping arm is connected to both ends of the second clamping cylinder. When the rubber sleeve reaches the position where the second clamping assembly is required to clamp, the second three-axis driving assembly moves the second clamping assembly to an accurate position near the rubber sleeve according to the command of the control system. Then, the second clamping cylinder drives the second clamping arms at both ends to close inward. The inner side of the second clamping arm contacts the rubber sleeve and gradually clamps it until the rubber sleeve is firmly clamped.

[0027] Reference Fig. 9 As shown, the third driving assembly is a third three-axis driving assembly, the stripper plate is provided with a limiting groove adapted to the end of the auxiliary tube, the limiting end of the auxiliary tube end is adapted to the limiting groove, the limiting end of the auxiliary tube is located on the second side of the limiting assembly, and after the end of the auxiliary tube is inserted into the limiting groove, the third three-axis driving assembly drives the stripper plate to move along a predetermined path. For example, in the operation of pulling out and removing the auxiliary tube from the rubber sleeve, the stripper plate moves along a specific direction, such as along the axial direction of the rubber sleeve, and due to the limiting effect of the limiting groove on the end of the auxiliary tube, the auxiliary tube moves with the stripper plate, thereby realizing the separation and movement of the auxiliary tube and the rubber sleeve.

[0028] Reference Figure 4-Figure 5 As shown, the material storage component includes: a lifting bracket, a tray, a driving motor, a screw pair, a transmission component, a linear drive, and a locking component. The tray is arranged on the lifting bracket, the screw pair is connected to the output end of the driving motor, the lifting bracket and the screw pair are connected, the transmission component is arranged on one side of the lifting bracket, the locking component is connected to the output end of the linear drive, the locking component can lock or unlock the tray, and the tray can be movably connected to the transmission component. The design of the lifting bracket and the tray can realize multi-layer storage of products to be worn. The lifting and lowering of the lifting bracket can be accurately controlled by the driving motor and the screw pair, so that the products to be worn at different layers can be easily obtained, which improves the space utilization and material management efficiency of the material storage component. The transmission component can smoothly transfer the tray from one position to another. Combined with the locking function of the linear drive and the locking component on the tray, it is ensured that the tray will not deviate, shake or fall off during the transmission process, thereby ensuring the safe transportation of the products to be worn and placing the products to be worn in the corresponding grooves of the tray. Then, according to the storage requirements, the drive motor starts, driving the lead screw pair to move, so that the lifting bracket rises or falls to the appropriate height, and the pallet is stored in the specified layer. When the pallet needs to be transferred to the feeding area, the linear drive component starts and pushes the locking component to lock the pallet. Then, the drive motor of the transmission component starts and starts to transfer the pallet from one side of the lifting bracket to the feeding area. During the transmission process, the transmission component continues to run and transports the pallet along a predetermined path. Due to the locking effect of the locking component, the pallet can stably follow the movement of the transmission component without shaking or falling off. When the pallet reaches the feeding area, the transmission component stops running. The linear drive component moves in the opposite direction, driving the locking component to unlock the pallet. At this time, the pallet can be docked with the feeding component and prepare for subsequent feeding operations.

[0029] Reference Figure 5-Figure 6As shown, the locking assembly includes: a column, a second linear drive member and a locking plate, the locking plate is connected to the output end of the second linear drive member to move along the first direction, the locking plate is provided with a slot adapted to the column, and the locking plate is provided with a bayonet connected to the slot along the second direction. When the tray needs to be locked, the second linear drive member is activated. The second linear drive member is a cylinder, and compressed air is introduced into the air inlet of the cylinder, and the piston extends, driving the locking plate to move toward the column along the first direction. The column first contacts the bayonet of the locking plate, and as the locking plate continues to move, the column enters the slot through the bayonet. When the column completely enters the slot, the tray is locked, and the second linear drive member stops working at this time, and the tray can be stably transported on the transmission assembly. When the tray reaches the destination, an unlocking operation needs to be performed. The second linear drive member works in the reverse direction. If it is a cylinder, the piston is retracted by exhausting air. The locking plate moves away from the column along the first direction driven by the piston. During the movement of the locking plate, the column is disengaged from the slot through the bayonet to complete the unlocking operation. After that, the tray can be operated subsequently, such as docking with the feeding assembly.

[0030] Reference Figure 7 As shown, the feeding assembly includes: a fourth drive assembly and a fourth clamping assembly, the fourth drive assembly is a fourth three-axis drive assembly, the fourth clamping assembly can clamp the product to be worn, when the rubber sleeve threading device does not start the feeding operation, the fourth three-axis drive assembly positions the fourth clamping assembly at the initial position, when feeding is required, the fourth clamping assembly moves to the vicinity of the product to be worn, and then the clamping cylinder of the fourth clamping assembly is inflated, the piston moves to close the clamping claws, firmly clamps the product to be worn, and the fourth clamping assembly starts to move under the drive of the fourth three-axis drive assembly. According to the instructions of the control system, the motors of the fourth three-axis drive assembly in three directions work together to move the fourth clamping assembly along a predetermined path. When the fourth clamping assembly transfers the product to be worn to the target position, the clamping cylinder of the fourth clamping assembly is exhausted, the piston moves in the opposite direction, the clamping claws open, and the product to be worn is released, completing a feeding operation. Afterwards, the fourth clamping assembly can return to the initial position under the drive of the fourth three-axis drive assembly as needed to prepare for the next feeding operation. Example

[0031] This embodiment discloses a control method for inserting a rubber sleeve, which uses the automotive wiring harness pre-insertion waterproof rubber sleeve mechanism as described in Example 1 to insert the rubber sleeve on the product to be inserted, including the following steps: Step S1: Move the product to be threaded to the limiting assembly so that the end of the rubber sleeve to be threaded and the pipe body to be threaded are coaxially aligned; The fourth three-axis drive assembly of the feeding assembly drives the screw to rotate through the motor, and the nut moves linearly on the screw, thereby driving the fourth clamping assembly on the slider to move. The clamping claw of the fourth clamping assembly clamps the product to be worn under the drive of the clamping cylinder. The positioning rod in the limit assembly moves along the first direction under the drive of the first cylinder, and the positioning seat supports the product. The two work together to ensure the accurate position of the product to be worn, thereby achieving coaxial alignment of the end of the rubber sleeve to be worn and the pipe body to be worn. After the sensor detects that the product has reached the correct position, the feeding assembly stops working.

[0032] Step S2: using the first clamping assembly to clamp the rubber sleeve to be inserted for the first time, so that the end of the rubber sleeve to be inserted passes through the auxiliary pipe and outward; The first three-axis driving assembly of the first clamping assembly moves the first clamping assembly to the starting position of the rubber sleeve. The first clamping cylinder drives the clamping plate to close and clamp the end of the rubber sleeve. Then, the first three-axis driving assembly drives the first clamping assembly to move along the first direction according to the program preset by the control system. Driven by the first clamping assembly, the end of the rubber sleeve can smoothly pass through the auxiliary tube and extend to a certain length because the inner diameter of the auxiliary tube is slightly larger than the outer diameter of the rubber sleeve.

[0033] Step S3: using the first clamping assembly to clamp the end of the rubber sleeve to be inserted for the second time, so that the end of the rubber sleeve to be inserted is moved to the third clamping assembly, and the length of the rubber sleeve to be inserted is equal to the preset target length; After the first clamping assembly clamps the end of the rubber sleeve again, the first three-axis drive assembly continues to drive the first clamping assembly to move at a preset speed and direction. The position detection device such as the photoelectric sensor continuously feeds back the movement distance information of the rubber sleeve to the control system, and the control system adjusts the motor speed and direction of the first three-axis drive assembly based on this information. When the end of the rubber sleeve reaches the third clamping assembly, the cylinder of the third clamping assembly drives the clamping claw to close and clamp the end of the rubber sleeve to ensure that the length of the rubber sleeve reaches the preset target length.

[0034] Step S4: clamping the two ends of the rubber sleeve to be pierced, using a material-shifting plate to clamp the end of the auxiliary tube, and driving the material-shifting plate to move along a first direction to separate the auxiliary tube from the product to be pierced; The second clamping assembly moves to one end of the rubber sleeve under the drive of the second three-axis drive assembly, and its second clamping cylinder drives the second clamping arm to close and clamp the rubber sleeve. The third clamping assembly has clamped the other end of the rubber sleeve. Under the drive of the third three-axis drive assembly, the material stripper plate clamps the limit groove to the end of the auxiliary tube through precise position control. Then, the motor of the third three-axis drive assembly drives the material stripper plate to move in the first direction. The material stripper plate is connected to the end of the auxiliary tube through the limit groove, overcomes the friction between the auxiliary tube and the product to be pierced, and pulls the auxiliary tube out of the product to be pierced.

[0035] Step S5: using the first clamping assembly to clamp the auxiliary tube for the third time, so that the auxiliary tube is separated from the rubber sleeve, and a product with the rubber sleeve is obtained.

[0036] The first clamping assembly is driven by the first three-axis drive assembly to move near the auxiliary tube, and the first clamping cylinder drives the clamping plate to close and clamp the auxiliary tube. Then, the motor of the first three-axis drive assembly drives the first clamping assembly to move in the first direction to pull the auxiliary tube out of the rubber sleeve. In this process, the control system adjusts the first three-axis drive assembly according to the material properties of the rubber sleeve and the auxiliary tube and the actual friction conditions to ensure that the auxiliary tube is smoothly separated from the rubber sleeve, and finally a product with a rubber sleeve is obtained.

[0037] After step S5, the auxiliary tube is also removed by using the third clamping assembly to clamp the auxiliary tube, using the first clamping assembly to clamp the rubber sleeve, and the fifth clamping assembly to clamp the auxiliary tube and move it in the first direction to complete the removal of the auxiliary tube. The fifth driving assembly drives the fifth clamping assembly to move the auxiliary tube to the receiving bin for recycling.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods.
