Description

Technical Field

[0001] The utility model relates to a terminal cutting and bending detection device, belonging to the technical field of terminal automatic forming equipment. Background Art

[0002] The industrial production process involves batch production of terminals, and the terminals are generally carried by material strips. There are a large number of preformed terminals on the material strips. In batch processing operations, the terminals on the material strips need to be bent, cut, separated, cleaned, and inspected, so as to achieve the classification of separated terminals.

[0003] Currently, there is a double-pin terminal, whose front end is formed by stamping. In order to meet the structural strength of the stamping and the effective connection with the material strip, there are connecting ribs between the two pins of the double-pin terminal and a connecting part between the double-pin terminal and the material strip. During the rear end operation, the connecting ribs and the connecting part need to be removed, and the pins need to be bent.

[0004] In traditional equipment, the method of bending first and then punching is adopted. The existence of connecting ribs will affect the bending accuracy. At the same time, when cutting and separating at the back end, unnecessary deformation will be caused, causing product quality problems.

[0041] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0043] The utility model provides a terminal cutting and bending detection device, such as Fig.11 As shown, it includes a material strip 100 equipped with a plurality of double-pin terminals 200, a connecting rib 300 is provided between the two pins of the double-pin terminal 200, a connecting portion 400 is provided between the double-pin terminal 200 and the material strip 100, and a bending column 500 is provided on the material strip for setting two columns spaced apart.

[0044] like Figures 1 to 10 As shown, it includes a material belt conveyor line 1 and a connecting rib cutting mechanism 2, a pin bending mechanism 3, and a terminal separation mechanism 4 which are sequentially arranged along the conveying direction of the material belt conveyor line.

[0045] The material belt conveyor line 1 comprises a material belt guide rail 11 for carrying the material belt, and a material belt stepping driving source 12 for driving the material belt to step and move. The material belt guide rail 11 is provided with matching grooves 111 arranged one-to-one corresponding to the bending columns.

[0046] The connecting rib cutting mechanism 2 comprises a supporting bottom die 21 having a groove conforming to the connecting rib, and a punching top die 22 having a lifting and lowering displacement and cooperating with the supporting bottom die.

[0047] The pin bending mechanism 3 includes a bending support portion 31 and a bending forming portion 32 with a linear stroke for cooperating with the bending support portion 31 . An escape gap is provided on the material strip guide rail to escape the bending support portion.

[0048] The terminal separation mechanism 4 comprises a top die 41 with a window 410 and a separation bottom die 42 with lifting and lowering displacement cooperating with the top die. A die-cutting matching portion corresponding to the connecting portion is provided on the window.

[0049] Specific implementation process and principle description:

[0050] During operation, the material belt 100 is mounted on the material belt guide rail 11 , and the bending column 500 is aligned and mounted by cooperating with the groove bar 111 to meet the material belt mounting accuracy requirements, and the material belt stepping drive source 12 realizes the stepping drive of the material belt 100 .

[0051] When entering the connecting rib cutting mechanism 2 , the material strip is located between the supporting bottom die 21 and the punching top die 22 , and the connecting rib 300 between the two pins of the double-pin terminal 200 on the material strip is punched out by the punching stroke of the punching top die 22 .

[0052] Then it enters the connecting rib cutting mechanism 2 . Due to the space of the avoidance interval, the double-pin terminal 200 can be supported on the bending support part 31 . At this time, the bending operation of the pins thereon is performed through the bending forming part 32 .

[0053] Then enter the terminal separation mechanism 4, at this time the separation bottom mold 42 is pushed upward, and the shear force of cutting is realized by the die-cutting matching part on the window to cut off the connection part 400, and the separated double-pin terminal 200 is pushed out from the window 410 to be exposed, and its exposure is convenient for the external picking mechanism to pick up and transfer materials.

[0054] In a specific embodiment, Figure 1 As shown, the material belt conveyor line 1 includes a first track segment corresponding to the connecting rib cutting mechanism and a second track segment corresponding to the terminal separation mechanism; there is a gap 110 between the first track segment and the second track segment. The first track segment and the second track segment are respectively provided with a material belt stepping drive source.

[0055] Specifically, both the front-end cutting and the rear-end cutting will have a certain impact and stress on the material strip. By setting the interval between the first track segment and the second track segment, the interval 110 can achieve blocking between the workstations on both sides and eliminate mutual interference. At the same time, it can provide a certain tension control, making the material strip operation more reliable.

[0056] In a specific embodiment, the material tape stepping driving source 12 includes a switching position carrier 121 with a linear switching displacement, and at least one lifting and lowering toggle portion 122 with a lifting and lowering displacement disposed on the switching position carrier.

[0057] That is, the interference between the lifting and lowering toggle part 122 and the material belt is realized by descending, so that when the switching position carrier 121 is displaced, it can play a role in advancing the material belt stepwise, and after it is reset, it can achieve equidistant advancement again.

[0058] This embodiment is only a specific example of the present case. It can also adopt gear plate drive, clamping stepping drive and other methods. It only needs to meet the mechanism of stepping drive of the material belt, which is within the protection scope of the present case.

[0059] In a specific embodiment, Figure 4 As shown, the pin bending mechanism 3 includes a bending carrier 33 with linear displacement, and the bending carrier 33 includes two spaced-apart partition plates 331, each of which is provided with a through channel 332 for the feed belt to pass through. The bending support portion and the bending forming portion are respectively mounted between the two partition plates.

[0060] Specifically, through this structural design, linear displacement adjustment can be achieved to meet the positioning accuracy adjustment requirements. In addition, two linear displacements are used to achieve coordinated bending operations, making the bending forming more diverse.

[0061] In a specific embodiment, Figures 1 to 10 As shown, it also includes a terminal detection mechanism 5, a terminal marking classification mechanism 6, and a turnover conveying mechanism 7.

[0062] The terminal detection mechanism 5 is provided with a detection station 50 , and the terminal marking classification mechanism 6 is provided with a marking station 61 .

[0063] The turnover conveying mechanism is provided with a first transfer part for switching displacement between the window opening and detection stations, and a second turnover part for switching displacement between the detection station and the marking station.

[0064] Specifically, when the current section of the double-pin terminal 200 is separated from the material strip and exposed through the window, the first transfer unit picks up the double-pin terminal 200 and transfers it to the inspection station 50. The terminal inspection mechanism 5 inspects the current double-pin terminal 200. After the inspection is completed, the second turnover unit picks it up to the marking station 61 for marking and classification of good and / or defective products.

[0065] It should be noted that, generally, the terminal inspection mechanism 5 is provided with a plurality of inspection stations 50. When there are multiple inspection stations 50, the turnover conveying mechanism only needs to be provided with a plurality of first transfer parts according to the station intervals, which can realize one-way material transfer between multiple stations.

[0066] In a specific embodiment, the terminal marking classification mechanism 6 includes a classification switching seat 60 with linear displacement, on which an NG storage chamber 62 and a good product marking portion are provided, and a marking station is arranged on the good product marking portion.

[0067] Specifically, when the test is qualified, the classification switching seat 60 switches the marking station to accept the material for good product marking. When the test is unqualified, the classification switching seat 60 switches the NG storage tank 62 to accept the material, thus realizing NG discharge.

[0068] In a specific embodiment, Figures 1 to 10 As shown, it also includes a plate swing mechanism 8 and a finished product turnover mechanism 9 for performing finished product turnover between the plate swing mechanism and the terminal marking and classification mechanism.

[0069] The tray swing mechanism 8 is used to carry the double-pin terminal 200 on the tray, and the finished product turnover mechanism 9 realizes the material transfer and tray loading, thus realizing the streamlined tray loading operation, which is efficient and smooth.

[0070] From the above description, it can be found that the terminal cutting and bending detection equipment of the utility model adopts the method of cutting the pins first and then bending them, so that the bending and forming quality of the product is guaranteed, and then the qualified rate of the product is guaranteed by separating it from the material strip. It can meet the online flow detection, screening and tray loading of the products after cutting, and the operation is smooth and stable. The overall layout is ingenious, the coordination between the various workstations is efficient and smooth, and the degree of automation is high, which greatly improves the production efficiency.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
