Description

Technical Field

[0001] This application relates to the field of hose fitting assembly technology, and in particular to an automated assembly device for hose fittings. Background Technology

[0002] Currently, the assembly of hose fittings mainly relies on manual operation. Workers need to manually assemble multiple parts, specifically, the fitting core, soft rubber ring, fitting nut, fitting cap, and plastic ring must be assembled sequentially. The fitting core has a groove for the fitting nut, and the fitting cap includes a head and a threaded tail; the outer diameter of the head is larger than that of the tail. When assembling the fitting nut and fitting cap, the operator must first place the fitting nut into the groove of the fitting core, and then tighten the fitting cap into the fitting nut.

[0003] However, manual operation is not only inefficient, but also has certain uncertainties. Due to the large number of parts and the high requirements for assembly precision, manual assembly can lead to unstable product quality and a high failure rate. Therefore, there is a need for equipment that can improve the efficiency and pass rate of assembling connector nuts and connector caps. Utility Model Content

[0004] To improve the efficiency and pass rate of assembling connector nuts and connector caps, this application provides an automatic assembly device for hose connectors.

[0005] The automatic assembly equipment for hose connectors provided in this application adopts the following technical solution:

[0006] An automatic assembly device for hose fittings includes a first feeding mechanism for feeding fitting nuts, a second feeding mechanism for feeding fitting caps, and an assembly mechanism for assembling fitting nuts to fitting caps. The assembly mechanism includes a transfer tray, a plurality of positioning seats mounted on the transfer tray, an automatic rotating assembly for clamping and tightening the fitting caps, a first driving member for driving the automatic rotating assembly to move up and down, and a second driving member for driving the automatic rotating assembly to move horizontally.

[0007] By adopting the above technical solution, a first feeding mechanism, a second feeding mechanism, and an assembly mechanism are set in the assembly equipment. The assembly mechanism includes a transfer plate, a positioning seat set on the transfer plate, an automatic rotation component, a first drive component, and a second drive component. This realizes the automatic feeding of connector nuts and connector caps. In addition, the transfer plate and positioning seat in the assembly mechanism can accurately transport and position parts, the automatic rotation component can clamp and tighten the connector caps, and the first and second drive components can make the automatic rotation component move flexibly, thereby improving the efficiency and pass rate of assembling connector nuts and connector caps.

[0008] Optionally, the positioning seat is provided with a first arrangement groove for arranging the connector nut and a second arrangement groove for arranging the connector core and coaxially connected to the first arrangement groove.

[0009] By adopting the above technical solution, the positioning seat is provided with a first arrangement groove for arranging the connector nut and a second arrangement groove for arranging the connector core and coaxially connected with the first arrangement groove. This can accurately position the connector nut and connector core, thereby improving the assembly efficiency and accuracy when assembling the connector nut and connector cap in the subsequent assembly process, and thus increasing the pass rate of the automatic hose connector assembly equipment for assembling connector nuts and connector caps.

[0010] Optionally, the positioning seat has a mounting through hole and a mounting bolt is provided in the mounting through hole, and the transfer plate has a mounting internal thread that mates with the mounting bolt.

[0011] By adopting the above technical solution, the positioning seat can be conveniently and firmly installed on the transfer plate by using the mounting bolts of the positioning seat and the mounting internal threads of the transfer plate. This ensures the stability of the positioning seat on the transfer plate, which helps to facilitate the smooth automatic assembly of the subsequent connector nuts and connector caps, and improves assembly efficiency and product qualification rate.

[0012] Optionally, the output end of the automatic rotating component is provided with two opposing clamping claws, and the clamping claws are provided with clamping grooves for clamping the connector screw cap.

[0013] By adopting the above technical solution, the automatic rotating component uses two opposing clamping claws with clamping grooves at its output end to make the automatic rotating component more stable when clamping the connector screw cap, which helps to facilitate the smooth operation of subsequent operations and thus improves the product assembly qualification rate.

[0014] Optionally, the first feeding mechanism includes a first feeding tray, a first feeding track connected to the outlet end of the first feeding tray, a first vibrator located below the first feeding track, and a feeding assembly. The first feeding track has a first guide groove for individual joint nuts to slide sequentially.

[0015] By adopting the above technical solution, the first material sorting tray is used to sort the disordered joint nuts, and the first vibrator, together with the first feeding track, makes the individual joint nuts slide along the first guide groove in sequence to achieve automatic feeding. This avoids the low efficiency and uncertainty of manual feeding, improves the feeding efficiency and accuracy of joint nuts, and thus improves the efficiency and pass rate of assembling joint nuts and joint caps.

[0016] Optionally, the first feeding track has a first guide ramp that slopes downward toward the assembly mechanism.

[0017] By adopting the above technical solution, the first feeding mechanism has a first guide slope that is inclined downward toward the assembly mechanism, which enables the joint nut to slide more smoothly toward the assembly mechanism under the action of gravity, thus helping to improve the feeding efficiency of the joint nut.

[0018] Optionally, the feeding assembly includes a third drive unit disposed at the output end of the first feeding track for lifting a single connector nut, a finger cylinder for clamping the connector nut, a fourth drive unit for driving the finger cylinder to move up and down, and a fifth drive unit for driving the finger cylinder to move horizontally.

[0019] By adopting the above technical solution, the third driving component lifts a single connector nut, the finger cylinder clamps the connector nut, and the fourth driving component realizes the lifting and lowering of the finger cylinder, and the fifth driving component realizes the horizontal movement of the finger cylinder. The feeding operation of the connector nut can be completed automatically, avoiding manual feeding, thereby improving the efficiency and accuracy of connector nut feeding.

[0020] Optionally, the feeding assembly further includes a sensor disposed at the output end of the first feeding track and used to detect the joint nut.

[0021] By adopting the above technical solution, a sensor for detecting connector nuts is set at the output end of the first feeding track. This ensures that the finger cylinder is driven to clamp the connector nut only when the connector nut is detected, which can avoid the situation of missing connector nuts during the feeding process and further improve the qualification rate of assembling connector nuts and connector caps.

[0022] Optionally, the second feeding mechanism includes a second feeding tray, a second feeding track connected to the outlet end of the second feeding tray, and a second vibrator located below the second feeding track. The second feeding track has a second guide groove for individual joint screw caps to slide sequentially.

[0023] By adopting the above technical solution, the second material tray is used to sort the connector screw caps, and the second vibrator is used to vibrate the second feeding track, allowing the connector screw caps to slide one by one along the second guide groove for feeding. This can realize automatic feeding of connector screw caps, replacing manual feeding and helping to improve the feeding efficiency of connector screw caps.

[0024] Optionally, the second feeding track has a second guide ramp that slopes downward toward the assembly mechanism.

[0025] By adopting the above technical solution, the second feeding track has a second guide slope that is inclined downward toward the assembly mechanism, which enables the connector screw cap to slide more smoothly toward the assembly mechanism under the action of gravity, thus helping to improve the feeding efficiency of the connector screw cap.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. An automatic assembly device for hose connectors, comprising a first feeding mechanism, a second feeding mechanism, and an assembly mechanism, wherein the assembly mechanism includes a transfer tray, a positioning seat disposed on the transfer tray, an automatic rotation component, a first driving component, and a second driving component, thereby improving the efficiency and pass rate of assembling connector nuts and connector caps;

[0028] 2. By setting a first arrangement slot and a second arrangement slot coaxially connected to the first arrangement slot in the positioning seat, wherein the connector nut can be arranged in the first arrangement slot and the connector core can be arranged in the second arrangement slot, it is helpful to position the connector nut and the connector core, thereby improving assembly efficiency and accuracy.

[0029] 3. By using the first guide slope of the first feeding mechanism, and the first guide slope is inclined downward toward the assembly mechanism, the joint nut can slide more smoothly toward the assembly mechanism under the action of gravity, thereby ensuring the feeding efficiency of the joint nut.
