[0034] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] like Figure 1-7 This is a schematic diagram of a connector terminal pressing device according to a preferred embodiment of the present invention. In this embodiment, the connector terminal pressing device includes a workbench 1. Support seats 2 are symmetrically fixedly installed on the center of the surface of the workbench 1. Guide rail frames 3 are fixedly installed on the top of the two support seats 2 to support the guide rail frames 3. From right to left, the rear end of the guide rail frame 3 is equipped with an ejection device 4, a current limiting device 5, a first pre-pressure device 6, a second pre-pressure device 7, and a pressing device 8. The ejection device 4 is located at the input end of the guide rail frame 3. A conveying device 9 is installed on the two support seats 2 below the guide rail frame 3 and is movable on the surface of the guide rail frame 3. A controller 10 is fixedly installed on the surface of the workbench 1 and is electrically connected to the ejection device 4, the current limiting device 5, the first pre-pressure device 6, the second pre-pressure device 7, the pressing device 8, and the conveying device 9.

[0037] Specifically, such as Figure 1-2As shown, the controller 10 controls the ejection device 4, flow limiting device 5, first pre-compression device 6, second pre-compression device 7, clamping device 8, and conveying device 9. The ejection device 4 is located at the guide rail frame 3, preventing material accumulation at the entrance of the guide rail frame 3. The flow limiting device 5 is used to limit the flow and prevent the base from continuing to be conveyed towards the first pre-compression device 6 if material jamming occurs during the processes of the first pre-compression device 6, the second pre-compression device 7, and the clamping device 8. The first pre-compression device 6 and the second pre-compression device 7 pre-compress the terminals at both ends of the base to prevent the clamping device 8 from directly pressing down, which would increase the scrap rate. After pre-compression by the first pre-compression device 6 and the second pre-compression device 7, the base reaches the clamping device 8 under the movement of the conveying device 9, and the clamping device 8 clamps the terminals. The base moves at the guide rail frame 3 via the conveying device 9.

[0038] In this embodiment, the first pre-compression device 6 and the second pre-compression device 7 adopt the same structural design.

[0039] In this embodiment, the ejection device 4 includes an ejection support frame 41, an ejection cylinder 42, a slide block 43, a slider 44, and an ejection block 45. The ejection support frame 41 is fixedly installed on the surface of the workbench 1. The ejection cylinder 42 is fixedly installed at the rear end of the top of the ejection support frame 41. The slide block 43 is fixedly connected to the top of the ejection support frame 41, and the slider 44 is slidably connected to the top of the slide block 43. The rear end face of the slider 44 is connected to the ejection cylinder 42. The front end face of the slider 44 is fixedly connected to the ejection block 45, and the ejection block 45 is movable at the input end of the guide rail frame 3.

[0040] Specifically, such as Figure 3 As shown, under the output push of the ejector cylinder 42, the slider 44 slides on the surface of the slide block 43. The ejector block 45 connected to the front end of the slider 44 is driven by the slider 44 sliding back and forth to push the base at the entrance of the guide rail frame 3, effectively solving the problem of the base getting stuck.

[0041] In this embodiment, the flow limiting device 5 includes a flow limiting support frame 51, a flow limiting cylinder 52, and a flow limiting block 53. The flow limiting support frame 51 is fixedly installed on the rear end face of the guide rail frame 3. The flow limiting cylinder 52 is fixedly installed on the top of the flow limiting support frame 51 directly above the guide rail frame 3. The output end of the flow limiting cylinder 52 is fixedly connected to the flow limiting block 53, and the flow limiting block 53 is movable on the top surface of the guide rail frame 3.

[0042] Specifically, such as Figure 3As shown, when the base encounters jamming or other issues during the processes of the first pre-compression device 6, the second pre-compression device 7, and the clamping device 8, the operator controls the flow-limiting cylinder 52 to rise, causing the flow-limiting block 53 to be misaligned with the flow-limiting port 33, thereby achieving the function of flow restriction. This facilitates the operator in better handling the jamming during the processes of the first pre-compression device 6, the second pre-compression device 7, and the clamping device 8.

[0043] In this embodiment, the first pre-compression device 6 includes a pre-compression support plate 61, a pre-compression cylinder 62, and a pre-compression assembly 63. The pre-compression support plate 61 is fixedly installed on the rear end face of the guide rail frame 3. The pre-compression cylinder 62 is fixedly installed on the top of the pre-compression support plate 61 directly above the guide rail frame 3, and the output end of the pre-compression cylinder 62 is fixedly connected to the pre-compression assembly 63. A guide groove 611 is formed on the surface of the pre-compression support plate 61 at a position opposite to the pre-compression assembly 63, and a pre-compression assembly is slidably connected in the guide groove 611. Component 63, the pre-compression component 63 is movable on the top surface of the guide rail frame 3. The pre-compression component 63 includes a connecting block 631, a pre-compression block 632 and a guide block 633. The connecting block 631 is fixedly connected to the output end of the pre-compression cylinder 62. The pre-compression block 632 is fixedly connected to the bottom of the connecting block 631 and the pre-compression block 632 is movable on the top surface of the guide rail frame 3. The guide block 633 is fixedly connected to the rear end of the pre-compression block 632. The end of the guide block 633 away from the pre-compression block 632 is slidably connected in the guide groove 611.

[0044] Specifically, such as Figure 5 As shown, under the drive of the pre-compression cylinder 62, the pre-compression block 632 is driven downward to pre-compress one end of the base. During the downward pre-compression displacement, the pre-compression block 632 plays a guiding role through the cooperation of the pre-compression block 632 and the guide groove 611, which effectively prevents the pre-compression block 632 from shifting position after long-term use, thus affecting the subsequent pressing work.

[0045] In this embodiment, as Figure 6-7 As shown, a limiting plate 31 is fixedly connected to the top surface of the guide rail frame 3, and a conveying cavity 32 is formed between the limiting plate 31 and the guide rail frame 3. A base slides in the conveying cavity 32, and the limiting plate 31 limits the sliding of the base in the conveying cavity 32, effectively preventing the base from detaching from the conveying cavity 32 under the influence of the conveying device 9. A movable opening 34 is provided in the middle of the surface of the conveying cavity 32, and the conveying device 9 is movably connected in the movable opening 34. An auxiliary support frame 11 is fixedly connected to the bottom of the guide rail frame 3 at an offset position, and the bottom of the auxiliary support frame 11 is connected to the surface of the workbench 1. The auxiliary support frame 11 can effectively support the guide rail frame 3. A flow limiting port 33 adapted to the flow limiting block 53 is provided on the surface of the guide rail frame 3, and the limiting block 53 moves in the flow limiting port 33.

[0046] In this embodiment, as Figure 4 As shown, the pressing device 8 includes an upper pressing assembly 81 and a lower pressing assembly 82. The upper pressing assembly 81 includes an upper pressing support plate 811, an upper pressing cylinder 812, an upper pressing slide 813, an upper pressing slider 814, and an upper pressing block 815. The upper pressing support plate 811 is fixedly installed on one side of the guide rail frame 3. The upper pressing cylinder 812 is fixedly installed above the surface of the upper pressing support plate 811. The upper pressing slide 813 is fixedly connected to the surface of the upper pressing support plate 811 directly below the upper pressing cylinder 812. The surface of the guide rail frame 3 is slidably connected to an upper pressure slider 814. The bottom of the upper pressure slider 814 is fixedly connected to an upper pressure block 815, and the upper pressure block 815 is movable on the surface of the guide rail frame 3. The lower pressure assembly 82 includes a lower pressure cylinder 821 and a lower pressure block 822. The lower pressure cylinder 821 is located at the opposite position of the upper pressure cylinder 812 and is fixedly installed on one side of the surface of the auxiliary support frame 11 by a fixing plate 823. The output end of the lower pressure cylinder 821 is fixedly connected to the lower pressure block 822, and the lower pressure block 822 moves towards the upper pressure block 815.

[0047] Specifically, during the terminal clamping process inside the base, the upper pressure cylinder 812 and the lower pressure cylinder 821 synchronously drive the upper pressure block 815 and the lower pressure block 822 toward the base. The lower pressure block 822 is positioned on the bottom surface of the base, while the upper pressure block 815 resists the terminals inside the base. The top positioning of the lower pressure block 822 can effectively prevent the base from deforming during the terminal clamping process, thereby reducing the scrap rate.

[0048] In this embodiment, as Figure 6-7 As shown, the conveying device 9 includes a conveying cylinder 91, a conveying frame 92, a conveying block 93, and a sliding component 94. The conveying cylinder 91 is fixedly installed on the surface of the support base 2. The output end of the conveying cylinder 91 is fixedly connected to the conveying frame 92. The top surface of the conveying frame 92 is fixedly connected to the conveying blocks 93 at equal intervals, and the conveying blocks 93 are movable within the movable opening 34. One side surface of the conveying frame 92 is connected to the inner wall of the auxiliary support frame 11 through the sliding component 94.

[0049] Specifically, during operation, the conveying cylinder 91 drives the conveying frame 92 to slide stably left and right under the guide rail frame 3 via the sliding component 94. The conveying block 93 connected to the top of the conveying frame 92 slides at the movable opening and performs the function of moving and conveying the base in the conveying cavity 32.

[0050] In this embodiment, as Figure 7As shown, the conveying block 93 includes a connecting block 931, a rotating plate 933, and a deflecting plate 935. The connecting block 931 is fixedly connected to the surface of the conveying frame 92. A rotating position 932 is provided on one side of the surface of the connecting block 931. The rotating position 932 is connected to the rotating plate 933 through a connecting pin 934. The bottom of the rotating plate 933 is located at the rear end and abuts against the surface of the rotating position 932. The top of the rotating plate 933 is fixedly connected to the deflecting plate 935, and the deflecting plate 935 adopts a triangular structure design.

[0051] In specific operation, when the conveyor frame 92 slides to the left, the front end of the actuating plate 935 contacts the base surface, and at the same time, the bottom rear end of the rotating plate 933 abuts against the rotating position 932, so that the rotating plate 933 will not rotate when it is resisted by the base, thereby driving the base to convey to the left. When the conveyor frame 92 slides to the right, since there is a cavity between the bottom front end of the rotating plate 933 and the rotating position 932, the rear inclined surface of the actuating plate 935 is resisted by the base, and the rotating plate 933 flips downward around the connecting pin 934, thereby achieving the function that the actuating plate 935 will not drive the base to convey to the right when the conveyor frame 92 slides to the right. Combining the above design, the function of conveying the base in the conveying cavity 32 is realized.

[0052] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted herein.
