Description

Technical Field

[0001] This invention relates to the technical field of terminal crimping devices, and more specifically to an automatic assembly device for wiring terminals. Background Technology

[0002] Terminals are components used to connect electrical equipment to external conductors. In electrical engineering, terminals often refer to wiring terminals, also called wire terminals, and are classified into single-hole, double-hole, socket, and hook types. Currently, a type of shell-shaped terminal with a cylindrical head is available on the market, with the following structure... Figure 1 As shown, terminal 9 includes a cylindrical plug 91 at the front end and a cylindrical crimping sleeve 92 formed at the rear end of plug 91. Two grooves 93 are formed on the opposite outer walls of the crimping sleeve 92. When a wire harness is inserted into the crimping sleeve 92, the sleeve wall is deformed and pressed onto the wire harness by tilting and pressing against the grooves 93, thus achieving a connection between terminal 9 and the wire harness. Currently, the wire harness connection of this terminal is generally done manually, mainly using wire crimping pliers to achieve the crimping between the terminal and the wire harness. However, manual crimping is inefficient, and multiple personnel are often required for this crimping station to improve production efficiency. However, with the gradual increase in labor costs in recent years, there is a need for equipment that can automatically perform crimping, which can reduce manpower and lower production costs while meeting production efficiency requirements.

A nut 24 is screwed onto the limiting bolts 23, and the nut 24 presses against the rear end face of the front clamping sleeve 21.

[0025] The gear transmission assembly 5 includes a driving gear 51 and a driven gear 52, which mesh with each other. The driving gear 51 is inserted and fixed on the rotating shaft of the motor 4. A connecting shaft is inserted and fixed on the driven gear 52, and the front end of the connecting shaft passes through the support plate 12 and is fixed to the rotating disk 212.

[0026] The crimping assembly 6 includes T-shaped pressure plates 61 distributed on both sides of the crimping slide 3, with T-shaped guide grooves 611 formed on the pressure plates 61 in the front and rear directions; the end of the crimping block 64 away from the crimping slide 3 is formed with a T-shaped connector 641, which is inserted into the guide groove 611 of the pressure plate 61; the pressure plate 61 is fitted with left and right guide posts 62, which are fixed to the outer walls on both sides of the crimping slide 3; a magnetic ring 63 is fitted and fixed to the end of the guide post 62 away from the crimping slide 3, and the pressure plate 61 is attracted to the magnetic ring 63; there are left and right connecting posts 66 between the pressure plates 61 on the lower side of the crimping slide 3, with one end of the connecting post 66 fixed to the pressure plate 61; the crimping cylinder 65 is fixed to the pressure plate 61 on one side of the crimping slide 3, and the piston rod of the crimping cylinder 65 passes through the pressure plate 61 and is fixed to the other end of the connecting post 66.

[0029] The stroke of the secondary feed cylinder 73 is not less than the length of the front clamping sleeve 21 on the terminal clamping assembly 2; a plug-shaped terminal 9 is inserted into the front clamping sleeve 21, and the length of the terminal 9 inserted into the front clamping sleeve 21 is less than the stroke of the secondary feed cylinder 73.

[0030] Working principle: The present invention is an automatic assembly device for terminal blocks. The specific working method of the automatic assembly device is as follows: the terminal 9 with the wire harness inserted is inserted into the front clamping sleeve 21 of the terminal clamping assembly 2 by manual or pneumatic clamping.

[0031] 1. Next, start the main feed cylinder 71 on the feed assembly 7. The main feed cylinder 71 drives the crimping slide 3 to move forward, so that the detection slot 32 on the crimping slide 3 moves to the groove 93 on the front side of the concave terminal 9. If the groove 93 is directly opposite the proximity switch sensor 81, that is, the groove 93 is facing upward, the proximity switch sensor 81 will not be triggered. The proximity switch sensor 81 provides feedback and starts the motor 4. The motor 4 drives the front clamping sleeve 21 to rotate, so that the groove 93 on the terminal 9 is moved and adjusted to both sides of the terminal 9.

[0032] 2. Then start the crimping assembly 6. The piston rod of the crimping cylinder 65 on the crimping assembly 6 retracts, driving the crimping block 64 to tilt and press the two sides of the terminal 9, thereby achieving crimping between the terminal 9 and the wire harness.

[0033] 3. Then, start the secondary feed cylinder 73 on the feed assembly 7. The pressing slide 3 drives the terminal 9 forward, so that the terminal 9 is disengaged from the terminal clamping assembly 2. Then the pressing cylinder 65 is reset. Under the magnetic force of the magnet ring 63, the pressing plate 61 drives the pressing block 64 to exit the terminal 9.

[0034] 4. Then, the secondary feed cylinder 73 and the main feed cylinder 71 of the feed assembly 7 are reset in succession. The rubber ring 22 at the front of the front clamping sleeve 21 prevents the terminal 9 from entering the front clamping sleeve 21. The feed assembly 7 will drive the terminal 9 to disengage from the crimping slide 3. Thus, when the feed assembly 7 is reset, the crimped terminal 9 falls between the two parts and can fall onto the conveyor belt and flow into the next process (such as soldering).

Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the invention; therefore, the scope of protection of the invention should be as set forth in the claims.
