Description

Technical Field

[0001] The invention relates to a processing mechanism for threaded hole riveting type connecting terminals, in particular to a connecting terminal pressing mechanism. Background Art

[0002] With the rapid development of economy and technology, mechanical automation has also achieved rapid development. However, for the installation of components of terminal blocks (mainly plastic base and plug-in assembly), it is difficult to use automated processing equipment for processing due to the irregular shapes of the components. Most of them rely on manual assembly by hand or with the assistance of tweezers. This assembly method is labor-intensive and time-consuming, with high labor intensity and low processing efficiency, resulting in high manufacturing costs. Later, there were some automated processing equipment on the market. Although the work efficiency has been improved to a certain extent, its structural design is complex, the equipment cost is high, and during the assembly process, the reliability is poor and the scrap rate is extremely high, resulting in a waste of material costs. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a terminal pressing mechanism which has compact structural design, high degree of automation, good assembly reliability and extremely fast and efficient assembly.

[0004] In order to solve the above technical problems, the terminal pressing mechanism of the present invention includes a horizontal conveying track for conveying a plastic base and a longitudinal conveying track arranged perpendicular to the horizontal track and used to convey plug-ins. The outlet of the longitudinal conveying track is connected to an plug-in pressing assembly located above the horizontal conveying track. A pressing mechanism for press-fitting the plug-in with the plastic base is arranged on the side of the plug-in pressing assembly. The plug-in entering the plug-in pressing assembly can be pressed and inserted into the plastic base by the pressing mechanism.

[0005] The insert pressing assembly includes two positioning seats fixedly installed on both sides of the longitudinal conveying track outlet, through grooves set on the side end surfaces of the two positioning seats, and elastic components respectively placed in the two through grooves. The front ends of the opposite surfaces of the two positioning seats are provided with corresponding limiting ribs, and the insert to be inserted is pressed against the limiting ribs.

[0006] The elastic component includes a stopper arranged in the through groove, a mounting plate for mounting on the side end surface of the positioning seat, and an elastic member arranged between the mounting plate and the stopper, through which the stopper can extend to the opposite surface of the positioning mounting seat to drag the insert to be inserted.

[0007] The upper sides of the opposite sides of the two stoppers are both provided with guiding slopes, and the lower edge of the insert is pressed against the guiding slopes. When the insert is pressed by the pressing mechanism, the elastic force of the elastic member can be overcome and the insert is pressed down into the plastic base.

[0008] The bottom surface of the through groove is provided with a limiting surface, the bottom surface of the stopper is provided with a limiting step matched with the limiting surface, and the side end surface of the stopper is provided with a blind hole for accommodating an elastic member, and the elastic member is limited in the blind hole.

[0009] The press-fitting mechanism comprises a mounting guide seat, a cylinder fixedly mounted on the mounting guide seat, and an insertion rod driven to rise and fall by the cylinder. The insertion rod can insert the insertion piece and press-fit it into the plastic base.

[0010] A floating joint is installed at the telescopic end of the cylinder, a connecting block is connected to the floating joint, and the insertion rod is connected to the connecting block.

[0011] A guide pressure seat is fixedly installed on the top of the two positioning seats, and a vertically arranged guide hole is provided on the guide pressure seat. The insertion rod can be guided by the guide hole and then plugged into the plug piece.

[0012] The longitudinal conveying track comprises a guide rail seat having a plug-in plate accommodating groove and guide steps arranged on the guide rail seat and located at two upper edges of the plug-in plate accommodating groove, and the top two side edges of the plug-in plate are limited by the guide steps.

[0013] The two outer ends of the front end of the guide rail seat are cut to form two connecting arms, and the inner end of the positioning seat is provided with a plug-in groove that cooperates with the connecting arm. The guide rail seat and the positioning seat are guided and installed through the cooperation of the connecting arm and the plug-in groove.

[0014] The advantages of the present invention are:

[0015] By setting up an insert pressing assembly connected at the exit of the longitudinal conveying track and located above the transverse conveying track, the insert can be directly pressed onto the plastic base using the insert pressing assembly. Its structural design is very clever and compact, easy to implement and easy to maintain. Only the insert pressing assembly and the pressing mechanism can be combined to achieve rapid assembly, which greatly improves the processing efficiency and makes the cost of the entire equipment very low.

[0016] (2) The insert press-fitting assembly is designed as a positioning seat with a limiting retaining edge and an elastic component structure, which can accurately transport the insert to the plug-in station, thereby improving the accuracy and reliability of the plug-in. At the same time, the structural design of the elastic component further improves the reliability of the press-fitting action.

[0017] (3) The elastic component is designed as a block with an elastic member installed, and the positional relationship between the two blocks is cleverly used to support or release the insert. The action is simple and easy to implement and has good action reliability.

[0018] (4) A guide press seat is provided on the top of the two positioning seats.

[0025] The following is a further detailed description of the terminal pressing mechanism of the present invention in conjunction with the accompanying drawings and specific embodiments.

[0026] The terminal pressing mechanism of the present invention comprises a transverse conveying track 2 for conveying a plastic base 1 and a longitudinal conveying track 4 arranged perpendicular to the transverse track and for conveying a plug-in 3. The transverse conveying track 2 comprises a guide slot seat having a guide slot and a groove in the guide slot. The two sides of the guide slot seat have different heights. The longitudinal conveying track 4 comprises a guide rail seat 24 having a plug-in receiving slot 23 and guide steps 25 arranged on the guide rail seat and located at the upper edges of the plug-in receiving slot. The plug-in 3 is conveyed from the vibrating screen in sequence and arranged on the longitudinal conveying track 4. The longitudinal conveying track 4 can vibrate and convey the plug-in. The plug-in 3 is moved by a horizontal plane and a water The bent piece at one end of the plane is composed of a bent piece, and the bent piece of the insert 3 can be guided and transported by the groove. The top and side edges of the insert 3 are limited by the guide steps. The outlet of the longitudinal conveying track 4 is connected with an insert pressing assembly 5 located above the transverse conveying track 2. As can be seen from the figure, the insert pressing assembly 5 includes two positioning seats 7 fixedly installed on both sides of the outlet of the longitudinal conveying track, and the bottoms of the two positioning seats are provided with a card slot that is engaged with a side edge with a higher height in the transverse conveying track, thereby realizing the fixed installation of the positioning seat, and a conveying groove for conveying the insert is formed between the two positioning seats 7, and the outlet of the conveying groove is directly opposite to the guide groove of the guide groove seat, and The plastic base conveyed from the transverse conveying track 2 can be conveyed at the outlet of the groove, and through grooves are set on the side end faces of the two positioning seats (the end faces perpendicular to the length direction of the transverse conveying track are defined as side end faces) and elastic components 8 are respectively arranged in the two through grooves. The elastic component 8 includes a stopper 10 arranged in the through groove, a mounting plate 11 for mounting on the side end face of the positioning seat, and an elastic member 12 arranged between the mounting plate and the stopper. The stopper can extend to the opposite surface of the positioning mounting seat through the elastic member 12 to drag the plug-in 3 to be inserted. Specifically, a limited position surface 13 is set on the bottom surface of the through groove, and a limit position surface 13 is set on the bottom surface of the stopper 10. There is a limiting step 14 that cooperates with the limiting surface, and a blind hole 15 for accommodating an elastic member is provided on the side end surface of the stopper. The elastic member is limited in the blind hole. The elastic member is a spring. The front ends of the opposite surfaces of the two positioning seats 7 (the outlet direction of the longitudinal conveying track 4 is defined as the front end, and the inlet direction of the longitudinal conveying track 4 is defined as the rear end) are provided with corresponding limiting ribs 9. The front end of the plug to be inserted is pressed against the limiting rib. A pressing mechanism 6 for pressing the plug and the plastic base is provided on the side of the plug pressing assembly 5. The plug 3 entering the plug pressing assembly can be pressed and inserted into the plastic base 1 by the pressing mechanism.

[0027] Furthermore, a guiding slope 13 can be provided on the upper side edges of the opposite sides of the two stoppers 10, and the lower edge of the horizontal surface of the insert 3 is pressed against the guiding slope. After the insert is pressed by the pressing mechanism 6, the elastic force of the elastic member can be overcome and the insert is pressed down into the plastic base 1. Through this structural design, the two guiding slopes 13 on the opposite sides of the two stoppers 10 drag the insert, thereby playing a supporting role.

[0028] Furthermore, the press-fitting mechanism 6 includes a mounting guide seat 16, a cylinder 17 fixedly mounted on the mounting guide seat, and an insertion rod 18 driven to rise and fall by the cylinder. The insertion rod 18 has a rod portion and a guide head arranged at the bottom end of the rod portion, so that the guide head can be inserted into the through hole (threaded hole) on the horizontal plane of the insert. When the insertion rod 18 presses the insert, the guide head at the bottom of the insertion rod 18 will first assist in guiding in the threaded hole of the insert, but the contraction of the spring cannot be accurately controlled. A guide groove 27 is formed on the inner side of the limiting retaining edge 9, so the guide groove 27 can be used to make the insert accurately installed in the plastic base, so that press-fitting can be achieved. The insertion rod 18 plugs the insert and presses it into the plastic base. Specifically, a floating joint 19 is installed at the telescopic end of the cylinder 17, and a connecting block 20 is connected to the floating joint 19, and the insertion rod 18 is connected to the connecting block 20.

[0029] Furthermore, a guide pressure seat 21 may be fixedly installed on the top of the two positioning seats 7, and the guide pressure seat has a vertically arranged guide hole 22, and the insertion rod 18 can be guided by the guide hole 22 to plug the plug-in piece.

[0030] In addition, for the guide rail seat, the two outer ends of the front end of the guide rail seat 24 are cut to form two connecting arms 26, and the inner end of the positioning seat 7 is provided with a plug-in groove that cooperates with the connecting arm. The guide rail seat 24 and the positioning seat are guided and installed through the connection arm and the plug-in groove.

[0031] During use, when the plastic base 1 reaches the insertion station (the location of the press-fit component 5) through the horizontal conveying track 2 and is directly below the outlet of the conveying groove, the insert 3 is vibrated by the longitudinal conveying track 4 to the insertion station (the location of the press-fit component 5). At this time, the insert rod 18 moves downward through the cylinder, the floating joint, and the connecting block. At this time, the two blocks are forced to retreat, leaving a channel to press the insert into the plastic base, and then the insert rod 18 is reset upward together through the cylinder to complete an insert installation action. It has been verified that the terminal press-fitting mechanism of the present invention can achieve a maximum efficiency of 20-25 products per minute, which is dozens of times that of manual labor.
