[0033] Please refer to Figures 1-4 This embodiment provides a pressing device, including:

[0034] The positioning assembly includes a base 110, a movable baffle 120, and an adjusting plate 130. The adjusting plate 130 is movably mounted on a fixed frame. The base 110 is fixed on the adjusting plate 130 and has several receiving cavities 111 for accommodating the connectors 200 to be pressed. The movable baffle 120 is slidably connected to the base 110, and several anti-misalignment blocks 121 are provided on the movable baffle 120. The anti-misalignment blocks 121 are adapted to the notches and slots on the connectors 200. The movable baffle 120 can slide relative to the base 110 so that the anti-misalignment blocks 121 can be inserted into or removed from the notches and slots.

[0035] The press-fitting assembly includes a press-fitting cylinder mounting plate 310, a plurality of press-fitting cylinders 320 and a plurality of press-fitting parts 330. The press-fitting cylinder mounting plate 310 is fixed on the adjusting plate 130. The press-fitting cylinders 320 are fixed on the press-fitting cylinder mounting plate 310 and correspond one-to-one with the press-fitting parts 330. The press-fitting parts 330 are correspondingly arranged with the receiving cavity 111. The press-fitting cylinders 320 are used to drive the press-fitting parts 330 to move so as to press the connectors 200 in the receiving cavity 111 onto a housing.

[0036] The pressing device provided in this embodiment can quickly position the connector 200 to be pressed using a positioning component. Then, the positioning connector 200 can be quickly pressed onto the housing using the pressing component. The entire device is compact, highly automated, and can simultaneously and accurately position and press multiple connectors 200, thereby reducing the labor intensity of workers and improving work efficiency. In addition, the design of the error-proof block 121 can mechanically prevent errors in the connector 200, ensuring the correct position of the connector 200.

[0037] It is understood that the shape of the receiving cavity 111 is designed based on the shape of the connector 200, and this utility model does not impose any limitations on the shape or number of the receiving cavities 111. In this embodiment, there are three receiving cavities 111, of which... Figures 1-3 The illustration only shows the case where the connector 200 is located in the central receiving cavity 111. Furthermore, the structural design of the anti-misalignment block 121 is also based on the shape of the connector 200, primarily to prevent the connector 200 from being upside down or placed backwards. For example, the anti-misalignment block 121 is a strip-shaped block. Before pressing, the anti-misalignment block 121 extends outwards and inserts into the notch groove of the connector 200. When it is confirmed that the connector 200 is in place and pressing is required, the movable baffle 120 slides relative to the base 110 to move the anti-misalignment block 121 out of the notch groove, so as not to affect the pressing of the connector 200. After pressing, the movable baffle 120 drives the anti-misalignment block 121 to reset.

[0038] In this embodiment, the sliding direction of the movable baffle 120 relative to the base 110 is perpendicular to the moving direction of the pressing component 330. For example... Figure 1As shown, a spatial rectangular coordinate system is established. The movable baffle 120 can slide relative to the base 110 along the X-axis, and the pressing component 330 moves along the Y-axis to press the connector 200. The Z-axis is the height direction.

[0039] Furthermore, the positioning component also includes several guide grooves 141 formed on the movable baffle 120 and several guide bolts 142 correspondingly disposed on the base 110, with the guide bolts 142 inserted into the corresponding guide grooves 141. The design of the guide grooves 141 and guide bolts 142 is mainly to guide the relative sliding between the movable baffle 120 and the base 110, thereby improving the motion accuracy. In this embodiment, there are two guide grooves 141 and two guide bolts 142. The guide grooves 141 have a certain length along the X direction, the length of which can be designed according to requirements. The guide bolts 142 are equal-height bolts, and their exterior can be covered with bushings.

[0040] In this embodiment, the positioning component further includes a material-stopping cylinder 150 mounted on the base 110, which is used to drive the movable baffle 120 to slide relative to the base 110. Of course, in addition to the cylinder, other driving mechanisms known in the art can also be used, and this utility model does not limit this.

[0041] Preferably, the positioning assembly further includes an in-situ detection sensor 160 disposed in each receiving cavity 111, the in-situ detection sensor 160 being used to detect whether a connector 200 is accommodated in each receiving cavity 111.

[0042] More preferably, the positioning assembly also includes an over-height detection sensor 170 disposed on the base 110. The over-height detection sensor 170 is used to detect whether the connectors 200 in each receiving cavity 111 are placed backwards. The over-height detection sensor 170 includes, for example, a laser generator and a laser receiver. The laser generator emits a laser beam. When the connectors 200 in each receiving cavity 111 are placed correctly, the laser receiver can receive the laser beam emitted by the laser generator. When at least one connector 200 in the receiving cavity 111 is placed backwards, the laser beam emitted by the laser generator is blocked by the connector 200, causing the laser receiver to be unable to receive the laser beam. This indicates that a connector 200 is placed backwards, triggering a real-time alarm to remind the assembly personnel to handle the situation promptly.

[0043] It should be noted that the in-situ detection sensor 160 and the ultra-high detection sensor 170 are both commercially available sensors, and this utility model will not elaborate on them.

[0044] Please continue to refer to Figure 1The pressing device also includes several adjusting components, each comprising a mounting base 410 and adjusting bolts 420. The mounting base 410 is fixed to the fixed frame, and the adjusting bolts 420 are vertically oriented and threadedly connected to the mounting base 410. The bottom end of the adjusting bolts 420 is a screw-in end, and the top end of the adjusting bolts 420 abuts against the bottom end of the adjusting plate 130. By setting the adjusting components, the vertical height of the adjusting plate 130 can be finely adjusted to ensure that the entire pressing device can be finely adjusted in vertical height relative to the fixed frame, thereby accommodating deviations during processing and assembly. In this embodiment, there are two adjusting components symmetrically arranged at both ends of the adjusting plate 130.

[0045] For example, turning the bottom of the adjusting bolt 420 clockwise can raise the adjusting plate 130, and conversely, turning the bottom of the adjusting bolt 420 counterclockwise can lower the adjusting plate 130.

[0046] Please refer to Figure 1 and Figure 4 The pressing component 330 includes a vertically connected pressing rod 331 and a pressing rod connecting plate 332. The pressing rod connecting plate 332 is vertically arranged and its top end is connected to one end of the pressing rod 331. The bottom end of the pressing rod connecting plate 332 is connected to the telescopic end of the pressing cylinder 320. The other end of the pressing rod 331 is used for pressing the connecting component 200. The pressing device also includes a pressing guide assembly, which includes a guide rail mounting plate 510 and a plurality of linear guide rails 520 disposed on the guide rail mounting plate 510. The guide rail mounting plate 510 is fixed on the adjusting plate 130. The pressing rod connecting plate 332 is provided with guide holes for the linear guide rails 520 to pass through.

[0047] In this embodiment, the pressure rod connecting plate 332 is arranged along the Z-axis, the pressure rod 331 is arranged along the Y-axis, the receiving cavity 111 is an open structure, the pressing cylinder 320 can drive the pressure rod connecting plate 332 to move along the Y-axis, thereby driving the pressure rod 331 to move to press the connector 200 onto the housing. The pressing guide assembly is used to guide the Y-axis movement of the pressing component 330, thereby improving the pressing accuracy and pressing stability.

[0048] It should be noted that each of the press-fitting components 330 is equipped with an independent press-fitting cylinder 320, which can adjust the press-fitting depth individually to ensure press-fitting stability.

[0049] Preferably, the bottom end of the pressure rod connecting plate 332 is connected to the telescopic end of the press-fit cylinder 320 via a floating joint 600. Using a floating joint 600 for connection automatically corrects positional deviations, reduces tolerance requirements, and improves connection reliability.

[0050] Preferred, such as Figure 5As shown, the other end face of the pressure rod 331 is provided with several negative pressure adsorption holes 333, and the pressure rod 331 has several negative pressure channels inside. A negative pressure connector 334 for connecting to a negative pressure generating device is provided on the pressure rod 331. The negative pressure adsorption holes 333 are connected to the negative pressure connector 334 through the negative pressure channels. In this embodiment, during the pressing process of the connector 200, the other end of the pressure rod 331 can adsorb the connector 200 through negative pressure, preventing the connector 200 from falling out of the receiving cavity 111 and ensuring the normal progress of the pressing process.

[0051] In summary, this utility model embodiment provides a pressing device that can quickly position the connector 200 to be pressed using a positioning component. Then, the pressing component can quickly press the positioned connector 200 onto the housing. The entire device is compact, highly automated, and can simultaneously and accurately position and press multiple connectors 200, thereby reducing worker workload and improving work efficiency. Furthermore, the design of the error-prevention block 121 provides mechanical error prevention for the connector 200, ensuring its correct position.

[0052] Furthermore, it should be understood that although the present invention has been disclosed above with reference to preferred embodiments, these embodiments are not intended to limit the present invention.
