Description

Technical Field

[0001] This utility model relates to the field of wire processing technology, and in particular to a tube insertion mechanism. Background Technology

[0002] The core function of a sleeving machine is to precisely fit insulating sleeves (such as heat shrink tubing, PVC tubing, etc.) onto wires, cables, copper wires, etc., replacing manual labor in the processes of sleeve cutting and sleeve fitting. It is widely used in industries such as electronics, electrical engineering, automobiles, and new energy. In actual production, it can automatically complete the sleeve feeding, cutting, wire positioning, and sleeve fitting actions by setting parameters such as sleeve length and fitting position according to requirements. For example, in transformer coil processing, sleeves can be fitted onto copper wire ends during winding gaps. In automotive wiring harness production, insulating sleeves are fitted onto wires of different specifications for protection or identification.

[0003] In existing technologies, the insertion of sheaths is usually done manually. This manual operation requires positioning each wire, cutting the sheath, and inserting it one by one. Each process relies on manual action, which is not only time-consuming per operation, but also affected by the decline in physical strength and attention of the operator. Efficiency will decrease significantly after a long period of operation. Especially when processing batches of wires, it is easy to cause production delays. At the same time, the stability of manual operation is insufficient. The length of the sheath cutting is prone to deviation due to differences in feel, and the insertion position may also deviate from the preset position due to hand tremors. This results in some wires having sheaths that are too short to provide sufficient protection, or too long, causing waste, or the position being offset, affecting subsequent assembly, directly reducing product consistency and increasing the defect rate. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sleeve insertion mechanism.

[0005] This utility model is achieved by the following technical solution: a sleeve insertion mechanism, including a sleeve fixing base plate, a sleeve cutting device at the bottom of the sleeve fixing base plate, a sleeve blocking device at the bottom of the sleeve fixing base plate, a sleeve clamping mold device at the bottom of the sleeve fixing base plate, a sleeve clamping mold front and back movement device at the bottom of the sleeve fixing base plate, a sleeve clamping mold left and right movement mechanism on the outer wall of the sleeve fixing base plate, and a sleeve clamping mold opening and closing device at the bottom of the sleeve fixing base plate.

[0006] Through the above technical solution, the sleeve clamping die forward and backward movement device and the sleeve clamping die left and right movement mechanism move the sleeve insertion groove of the sleeve clamping die device to the outlet position for alignment. The sleeve blocking device opens, and the baffle blocks the lower end of the sleeve insertion groove. The sleeve clamping die opening and closing device uses the cam structure principle to open the sleeve insertion groove to the corresponding position. The external sleeve feeding mechanism feeds the set sleeve length into the sleeve insertion groove. After feeding, the sleeve clamping die opening and closing device automatically returns to zero, the sleeve groove closes to clamp the sleeve, and the sleeve clamping die forward and backward movement device and the sleeve clamping die left and right movement mechanism move the upper end of the sleeve insertion groove of the sleeve clamping die device to the inlet and outlet position of the threading needle for alignment. The entire cycle ends. Through automated operation of the equipment, the labor intensity of workers can be reduced and the production efficiency of the operation can be improved. At the same time, automation improves the accuracy of the sleeve insertion position.

[0007] As a further improvement to the above solution, the sleeve clamping mold left and right movement mechanism includes a fixed seat, which is fixedly connected to the outer wall of the sleeve fixed seat plate.

[0008] As a further improvement to the above solution, a motor is fixedly connected to the outer wall of the end of the fixed base away from the sleeve fixed base plate, and a pulley is fixedly connected to the output end of the motor.

[0009] As a further improvement to the above solution, a belt is connected to the outer wall of the pulley, and two pulleys are provided, which are symmetrically arranged with the belt as the center.

The sleeve blocking device opens, and the baffle blocks the lower end of the sleeve insertion slot. The sleeve clamping die opening and closing device uses the cam structure principle to open the sleeve insertion slot to the corresponding position. The external sleeve feeding mechanism feeds the set sleeve length into the sleeve insertion slot. After feeding, the sleeve clamping die opening and closing device automatically returns to zero, the sleeve groove closes to clamp the sleeve, and the sleeve clamping die forward and backward movement device and the sleeve clamping die left and right movement mechanism move the upper end of the sleeve insertion slot of the sleeve clamping die device to the inlet and outlet position of the threading needle for alignment.

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example:

[0017] Please combine Figure 1-4 A sleeve insertion mechanism according to this embodiment includes a sleeve fixing base plate 1, a sleeve cutting device 2 provided at the bottom of the sleeve fixing base plate 1, a sleeve blocking device 3 provided at the bottom of the sleeve fixing base plate 1, a sleeve clamping device 4 provided at the bottom of the sleeve fixing base plate 1, a sleeve clamping device 5 provided at the bottom of the sleeve fixing base plate 1, a sleeve clamping device 6 provided on the outer wall of the sleeve fixing base plate 1, and a sleeve clamping device 7 provided at the bottom of the sleeve fixing base plate 1.

[0018] Based on the exit position of the cannula needle, the cannula clamping device 5 and the cannula clamping device 6 move the upper end of the cannula insertion groove of the cannula clamping device 4 to align with the cannula needle exit position. Then, the cannula blocking device 3 opens, and the baffle blocks the lower end of the cannula insertion groove to prevent the cannula from being inserted too long or falling from below after being cut. The motor of the cannula clamping device 7 rotates according to the system parameter settings, and uses its cam structure principle to open the cannula insertion groove to the corresponding position, so that the cannula can be inserted into the groove more easily. At this time, the external cannula feeding mechanism will feed the set cannula length into the cannula insertion groove. After feeding, the motor of the cannula clamping device 7 will automatically return to zero, and the cannula groove will close. The inserted sleeve is clamped, and the sleeve cutting device 2 moves back and forth once to cut the sleeve into the groove. At the same time, the sleeve blocking device 3 closes and returns to its original position. Finally, the sleeve clamping mold, with the sleeve inserted into the groove, awaits the next instruction. The sleeve clamping mold forward and backward movement device 5 and the sleeve clamping mold left and right movement mechanism 6 move the upper end of the sleeve insertion groove of the sleeve clamping mold device 4 to the inlet and outlet position of the threading needle to align with the threading. The entire cycle ends. The automated operation of the equipment can reduce the labor intensity of workers and improve the production efficiency of the operation. At the same time, automation improves the accuracy of the insertion position, thereby ensuring accurate protection of the wire sleeve, avoiding waste caused by excessive length, improving product consistency, and reducing the defect rate.

[0019] The sleeve clamping mold left and right movement mechanism 6 includes a fixed seat 601, which is fixedly connected to the outer wall of the sleeve fixed seat plate 1.

[0020] A motor 602 is fixedly connected to the outer wall of the end of the fixed base 601 away from the sleeve fixed base plate 1, and a pulley 603 is fixedly connected to the output end of the motor 602.

[0021] The outer wall of the pulley 603 is connected to a belt 604. There are two pulleys 603, which are symmetrically arranged with the belt 604 as the center.

[0022] A fixing block 605 is rotatably connected to the outer wall of the pulley 603, and the fixing block 605 is fixedly connected to the outer wall of the sleeve fixing seat plate 1.

[0023] A connecting plate 606 is fixedly connected to the outer wall of the belt 604, and a guide block 607 is fixedly connected to the outer wall of the connecting plate 606.

[0024] A guide plate 608 is slidably connected to the outer wall of the guide block 607. The guide plate 608 is fixedly connected to the outer wall of the sleeve fixing seat plate 1. A support plate 609 is fixedly connected to the end of the connecting plate 606 away from the belt 604.

[0025] Motor 602 drives pulley 603 to rotate. There are two pulleys 603. The pulley 603 furthest from motor 602 rotates with fixed block 605. Fixed block 605 ensures stable rotation of pulley 603. Pulley 603 drives connecting plate 606 to move through belt 604. Connecting plate 606 slides on the outer wall of guide plate 608 through guide block 607. Guide plate 608 provides guidance for the movement of guide block 607. Connecting plate 606 is fixed to support plate 609, so that support plate 609 simultaneously drives the casing cutting device 2, casing blocking device 3, casing clamping device 4, casing clamping device forward and backward movement device 5, and casing clamping device opening and closing device 7 to move simultaneously.

[0026] The implementation principle of the cannula insertion mechanism in this embodiment is as follows: Based on the exit position of the cannula needle, the cannula clamping device 5 (forward and backward movement) and the cannula clamping device 6 (left and right movement) move the upper end of the cannula insertion groove of the cannula clamping device 4 to align with the cannula needle exit position. Then, the cannula blocking device 3 opens, and the baffle blocks the lower end of the cannula insertion groove, thereby preventing the cannula from being inserted too long or falling from below after being cut. The motor of the cannula clamping device 7 rotates according to the system parameter settings, utilizing its cam structure principle to open the cannula insertion groove to the corresponding position, making it easier to insert the cannula. Once the sleeve is inserted into the slot, the external sleeve feeding mechanism will deliver the set sleeve length into the sleeve insertion slot. After delivery, the motor of the sleeve clamping device 7 will automatically return to zero, the sleeve slot will close, and the inserted sleeve will be clamped. Next, the sleeve cutting device 2 will move back and forth once to cut the sleeve into the slot. At the same time, the sleeve blocking device 3 will close and return to its original position. Finally, the sleeve clamping device, with the sleeve inserted into the slot, awaits the next instruction. The sleeve clamping device 5 and the sleeve clamping device 6 will move the upper end of the sleeve insertion slot of the sleeve clamping device 4 to the inlet and outlet position of the threading needle to align with the threading needle. The entire cycle is complete. Automated operation of the equipment reduces the labor intensity of workers and improves production efficiency. Automation also improves the accuracy of the wire sheathing position, ensuring accurate protection of the wire sheath, avoiding waste due to excessive length, improving product consistency, and reducing the defect rate. A fixing seat 601 is fixed to the outer wall of the sheath fixing plate 1, and the fixing seat 601 supports the motor 602. The motor 602 drives the pulleys 603 to rotate. There are two pulleys 603. The pulley 603 furthest from the motor 602 is connected to the fixing block. Rotation of 605 ensures stable rotation of pulley 603 via fixing block 605. Pulley 603 drives connecting plate 606 to move via belt 604. Connecting plate 606 slides on outer wall of guide plate 608 via guide block 607. Guide plate 608 provides guidance for the movement of guide block 607. Connecting plate 606 is fixed to support plate 609, thereby enabling support plate 609 to simultaneously drive the casing cutting device 2, casing blocking device 3, casing clamping device 4, casing clamping device forward and backward movement device 5, and casing clamping device opening and closing device 7 to move simultaneously.
