Technical Field

[0001] This utility model relates to the field of terminal crimping technology, specifically to an automatic terminal crimping station. Background Technology

[0002] In the field of modern electronic manufacturing and electrical connection, terminal blocks, as key components for circuit connection, are widely used in automotive wiring harnesses, home appliances, industrial control equipment and other fields. The quality of their crimping directly affects the reliability and safety of electrical connections. According to CN118523142B, a terminal crimping device is disclosed. This technology discloses "a terminal crimping device, belonging to the field of terminal crimping machine technology, including a terminal crimping machine body, a wire storage box, a tidying mechanism, and a pushing mechanism. The wire storage box is fixed on the frame; the tidying mechanism includes a tidying chamber and a tidying plate, the inner cavity of the tidying chamber is connected to the discharge port, and the tidying plate is lifted and lowered on the tidying chamber; the pushing mechanism includes a pushing component and a conveying component, the pushing component is used to remove the wire strips in the inner cavity of the tidying chamber located away from the discharge port from the tidying chamber, and the conveying component is used to convey the wire strips removed from the tidying chamber by the pushing component to the crimping station of the terminal crimping machine body." It has the technical effect of "setting up a wire storage box, a tidying mechanism, and a pushing mechanism, which can convey a batch of wire strips one by one to the crimping station of the terminal crimping machine body, thereby cooperating with the terminal crimping machine body to realize automatic placement of wire strips and automatic crimping, improving the terminal crimping efficiency of electric vehicle controller wire strips." Existing automatic crimping equipment for terminals suffers from insufficient positioning stability during continuous feeding. Due to the motion inertia of the conveying mechanism and the accumulation of mechanical clearance, the workpiece is prone to positional drift after multiple feeding steps, which leads to a gradual decrease in the positioning accuracy of subsequent crimping processes. This error directly affects the concentricity of the crimping between the terminal and the cable, resulting in quality defects such as poor contact or substandard mechanical strength.

The crimping station ensures positioning accuracy through a three-stage feeding system. Combined with a linear layout of cutting, crimping, and leveling stations, it achieves efficient assembly line operation, ensuring both processing consistency and improved production efficiency. It is particularly suitable for mass production of precision terminals.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic crimping station for wiring terminals, comprising a processing table and a workpiece, wherein the processing table is equipped with a processing mechanism for processing the workpiece, the processing mechanism comprising: The main components include a limiting guide fixed to the top of the processing table; The conveying assembly includes a mounting plate fixed to the bottom of the processing table, a slide plate that is laterally slidably mounted on the front end of the mounting plate, a horizontal plate that is longitudinally slidably mounted on the slide plate, a number of push blocks that are evenly distributed on the top of the horizontal plate, a first cylinder that is mounted on the front end of the slide plate and is used to drive the horizontal plate to move longitudinally, and a second cylinder that is mounted on the left side of the front end of the mounting plate and is used to drive the slide plate to move laterally.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 5 This utility model provides a technical solution: an automatic crimping station for wiring terminals, including a processing table 3 and a workpiece 2. The processing table 3 is equipped with a processing mechanism 1 for processing the workpiece 2. The processing mechanism 1 includes: The main component 11 includes a limiting guide seat 111 fixed to the top of the processing table 3; The conveying assembly 12 includes a mounting plate 121 fixed to the bottom of the processing table 3. A slide plate 122 is slidably mounted on the front end of the mounting plate 121. A horizontal plate 123 is slidably mounted on the slide plate 122. Several push blocks 124 are fixed on the top of the horizontal plate 123 at equal intervals. A first cylinder 125 is mounted on the front end of the slide plate 122 and is used to drive the horizontal plate 123 to move longitudinally. A second cylinder 126 is mounted on the left side of the front end of the mounting plate 121 and is used to drive the slide plate 122 to move laterally. The execution component 13 includes a cutting component 131 disposed on the left side of the processing table 3, a pressing component 132 disposed in the middle of the processing table 3, and a flattening component 133 disposed on the right side of the processing table 3.

[0017] In this embodiment, the workpiece 2 is placed in the limiting guide seat 111, and then the first cylinder 125 drives the horizontal plate 123 to lift the push block 124. Then, the second cylinder 126 drives the slide plate 122 to push the horizontal plate 123 on the push block 124 to move the workpiece 2 one station to the right. Then, the first cylinder 125 drives the push block 124 on the horizontal plate 123 to lower, and then the second cylinder 126 drives the slide plate 122 to move the push block 124 on the horizontal plate 123 to the left to reset. The above steps are repeated to achieve intermittent feeding of the workpiece 2. By adopting the three-stage motion logic of lifting, pushing and resetting, stable and reliable intermittent feeding is achieved, so that each workpiece 2 can obtain a consistent conveying stroke, ensuring the consistency of the processing position. Together with the cutting component 131, the pressing component 132 and the flattening component 133 arranged linearly along the processing table 3, a complete processing production line is formed.

[0018] Specifically, the conveying assembly 12 also includes a mounting bracket 127 fixed to the output end of the second cylinder 126, on which a third cylinder 128 is mounted, and the output end of the third cylinder 128 is fixed to the slide plate 122.

[0019] In this embodiment, the output end of the third cylinder 128 drives the slide plate 122 to drive the push block 124 on the horizontal plate 123 to make lateral fine adjustments; the micro-motion characteristic effectively compensates for the mechanical gaps and positioning errors that may exist in the main conveying system, ensuring that each terminal 2 can accurately reach the crimping position.

[0020] Specifically, the main body component 11 also includes an anti-deviation block 112 fixed in the middle of the top of the limiting guide seat 111, a first groove 113 fixed in the middle of the front end of the limiting guide seat 111, and a second groove 114 fixed on the left side of the front end of the limiting guide seat 111.

[0021] In this embodiment, when the workpiece 2 moves to the processing area of ​​the crimping component 132, the anti-deviation block 112 applies vertical constraint to prevent the plug 21 from tilting up during the crimping process between the terminal head 22 and the cable.

[0022] Specifically, the workpiece 2 includes a plug 21 placed in the limiting guide seat 111, and a terminal head 22 is fixed on the plug 21.

[0023] Specifically, the cutting component 131 includes a first stand 1311 fixed on the top left side of the processing table 3, a first slider 1312 slidably installed inside the first stand 1311, a cutter head 1313 installed at the lower end of the first slider 1312, and a first hydraulic cylinder 1314 installed at the upper end of the first stand 1311 for driving the first slider 1312.

[0024] In this embodiment, after the cable is placed in the positioning position of the second groove 114, the first hydraulic cylinder 1314 pushes the first slider 1312 to move steadily down along the guide rail of the first stand 1311, so that the cutter head 1313 can perform circumferential cutting on the cable sheath with a preset stroke.

[0025] Specifically, the pressing component 132 includes a second stand 1321 fixed on the middle side of the top of the processing table 3, a second slider 1322 slidably installed inside the second stand 1321, a die head 1323 installed at the lower end of the second slider 1322, and a second hydraulic cylinder 1324 installed at the upper end of the second stand 1321 for driving the second slider 1322.

[0026] In this embodiment, when the cable is precisely placed on the first groove 113 and the terminal 2 is positioned to the crimping station by the feeding mechanism, the second hydraulic cylinder 1324 pushes the second slider 1322 to press vertically down along the second stand 1321, so that the die head 1323 presses the terminal 2 and the cable conductor with constant pressure.

[0027] Specifically, the flattening assembly 133 includes a third stand 1331 fixed on the top right side of the processing table 3, a third slider 1332 slidably installed inside the third stand 1331, a pressure roller 1333 rotatably installed at the lower end of the third slider 1332, and a third hydraulic cylinder 1334 installed at the upper end of the third stand 1331 for driving the third slider 1332.

[0028] In this embodiment, when the crimped cable and terminal move to the processing area of ​​the flattening assembly 133, the third hydraulic cylinder 1334 pushes the third slider 1332 downward, so that the pressure roller 1333 contacts the cable surface and eliminates the deformation or stress generated during the crimping process by rolling and pressing. The rotation design of the pressure roller 1333 avoids the cable surface scratches that may be caused by traditional fixed pressure blocks, ensuring that the appearance of the wire harness is flat. In addition, the slight warping of the terminal after crimping is effectively corrected by uniform pressure, improving the connection stability between the terminal and the cable.

[0029] The working principle and usage process of this utility model are as follows: First, the workpiece 2 is placed in the limiting guide seat 111. Then, the first cylinder 125 drives the horizontal plate 123 to lift the push block 124. Then, the second cylinder 126 drives the slide plate 122 to push the horizontal plate 123 on the push block 124 to move the workpiece 2 to the right by one station. Then, the first cylinder 125 drives the push block 124 on the horizontal plate 123 to lower. Then, the second cylinder 126 drives the slide plate 122 to move the push block 124 on the horizontal plate 123 to the left to reset. The above steps are repeated to achieve intermittent feeding of the workpiece 2. Then, after the cable is placed in the positioning position of the second groove 114, the first hydraulic cylinder 1314 pushes the first slider 1312 to move steadily down along the guide rail of the first stand 1311, so that the cutter head 1313 can perform a circumferential cut on the cable sheath with a preset stroke. When the workpiece 2 is transported to the processing area of ​​the crimping component 132, after the cable is placed on the first groove 113 and the terminal 2 is positioned to the crimping station by the feeding mechanism, the second hydraulic cylinder 1324 pushes the second slider 1322 to press vertically down along the second stand 1321, so that the die head 1323 presses the terminal 2 and the cable conductor with constant pressure. Finally, when the workpiece 2 is conveyed to the processing area of ​​the flattening assembly 133, the third hydraulic cylinder 1334 pushes the third slider 1332 down, so that the pressure roller 1333 contacts the cable surface and eliminates the deformation or stress generated during the pressing process by rolling and pressing.
