Description

Technical Field

[0001] The invention relates to the technical field of tubular terminal assembly, in particular to a tubular terminal assembly machine. Background Art

[0002] A tubular terminal is a type of cold-pressed terminal, also known as a tubular cold-pressed end or tubular wiring terminal. A tubular terminal is a tinned copper sleeve primarily used to secure the individual strands of stranded conductors. Adding a cold-pressed terminal to a conductor imparts the properties of a stranded conductor to a solid conductor, providing a reliable electrical connection, protecting against mechanical influences, and facilitating wiring and rewiring. It is widely used in charging systems, control systems, and various electrical equipment for electronic and automated equipment.

[0003] When assembling the joint tube terminal, the copper tube needs to be placed inside the joint sleeve, and the sleeve is pre-pressed with a special pre-assembly tool to ensure that the ferrule cutting edge is embedded in the raised band on the surface of the copper tube and covers more than 80% of the ferrule end face. Then, use crimping pliers to perform a second crimping on the sleeve to form a hexagonal shrinkage structure to achieve mechanical locking between the copper tube and the sleeve.

[0004] However, the existing tube-type terminals have the following deficiencies during assembly:

[0005] There is no assembly equipment for joint tube terminals in the existing technology. The assembly of the joint sheath and the copper tube needs to be completed manually, which relies too much on manual labor, resulting in low assembly efficiency. In addition, manual assembly has a certain degree of subjectivity. The assembly process requires manual crimping or connection.

The sleeve is positioned within the sleeve trough 8 by the push-in slider 10. A servo motor 17 drives the crankshaft shaft 24, which acts on the copper tube push-in assembly, cooperating with the forming assembly to move linearly up and down, pushing the copper tube into the sleeve. One rotation (360 degrees) of the crankshaft shaft 24 constitutes one forming cycle, resulting in two products being assembled at once.

The copper tube push-in cam 9 advances the copper tube to a position above the sleeve. The copper tube push-in assembly then moves vertically, pressing the copper tube into the sleeve. Simultaneously, the sleeve positioning cam 27 drives the sleeve positioning forming slider 28 to move upward, positioning the sleeve.

[0041] The effect achieved by the entire embodiment 4 is as follows: the above-mentioned components drive a synchronous wheel 21 to rotate through the servo motor 17. Since the outer walls of the two synchronous wheels 21 are engaged with the synchronous belt 22, when one of the synchronous wheels 21 rotates, it will drive the synchronous belt 22 to engage with the synchronous wheel 21, so that the other synchronous wheel 21 also rotates. The connecting shaft of the passively rotating synchronous wheel 21 is fixedly connected to the main shaft of the encoder 19 fixedly installed at the bottom of the workbench 20, and the encoder 19 is used to accurately record and control the rotation angle of the output shaft of the servo motor 17. , improving assembly precision. When the servo motor 17 rotates, it drives the crankshaft shaft 24, acting on the copper tube push-in assembly. This, in conjunction with the forming assembly, moves linearly up and down, pushing the copper tube into the interior of the attached sheath. One rotation (360 degrees) of the crankshaft shaft 24 constitutes one forming cycle, forming two products at a time. During one forming cycle, the crankshaft rotation drives the upper and lower slider mounting plates in linear up and down motion. The copper tube push-in cam 9 drives the push-in slider 10 in forward and backward motion. The sheath positioning stroke cam 27 drives the sheath positioning forming slider 28 in up and down motion. The copper tube push-in cam 9 advances the copper tube to a position above the sheath. The copper tube push-in assembly then moves vertically, pressing the copper tube into the sheath. Simultaneously, the sheath positioning stroke cam 27 drives the sheath positioning forming slider 28 in an upward motion, positioning the attached sheath. The terminal forming assembly rivets the attached sheath to the copper tube. When the product is riveted and rises to 270 degrees, the sheath feed servo motor 17 completes one feed. At the same time, a CCD visual inspection camera 7 is fixedly installed on the top of the workbench 20, and a CCD visual inspection computer 16 is fixedly installed on the top of the frame 1.

The detection probe of the CCD visual inspection camera 7 is installed above the sheath material trough 8. The assembled tube-type terminal passes under the detection probe of the CCD visual inspection camera 7. The CCD visual inspection camera 7 transmits the detected image data to the CCD visual inspection computer 16 through a signal. The CCD visual inspection computer 16 analyzes and processes the received image data to determine whether the assembly of the copper tube and the associated sheath meets the assembly specifications to avoid the production of defective products.

[0042] The working principle of the whole equipment is as follows: when in use, the device can be divided into a copper tube pressing station, a product forming station, and a sheath feeding station according to its function. The three stations are used to press the copper tube into the internal part of the associated sheath, crimp the associated sheath and the copper tube, and automatically feed the associated sheath.

[0043] When equipping the copper tube and the associated sheath, first, place the copper tube inside the feeding vibration plate 2.

The sheath is set inside the sheath trough 8. The copper tube is pushed into the assembly, and the forming assembly is installed on the upper and lower slider mounting plates to form a copper tube pressing station and a product forming station. A servo motor 17 drives the crankshaft shaft 24, which acts on the copper tube pusher assembly, which in turn moves up and down linearly in conjunction with the forming assembly, pushing the copper tube into the interior of the attached sleeve. One rotation (360 degrees) of the crankshaft shaft 24 constitutes one forming cycle, forming two products at a time. During one forming cycle, the crankshaft rotation drives the upper and lower slider mounting plates in vertical linear motion. The copper tube pusher cam 9 drives the pusher slider 10 in forward and backward motion, and the sleeve positioning cam 27 drives the sleeve positioning and forming slider 28 in up and down motion. The copper tube pusher cam 9 advances the copper tube to a position above the sleeve. The copper tube pusher assembly then moves up and down, pressing the copper tube into the sleeve. Simultaneously, the sleeve positioning cam 27 drives the sleeve positioning and forming slider 28 in an upward motion, positioning the attached sleeve. The terminal forming assembly rivets the attached sleeve to the copper tube. When the product is riveted and rises to 270 degrees, the sleeve feed servo motor 17 completes one feed. This cycle repeats. The assembled conjoined tubular terminal passes under the detection probe of the CCD visual inspection camera 7, and the CCD visual inspection camera 7 transmits the detected image data to the CCD visual inspection computer 16 through a signal. The CCD visual inspection computer 16 analyzes and processes the received image data to determine whether the assembly of the copper tube and the conjoined sheath complies with the assembly specifications to avoid the production of defective products.
