Description

Technical Field

[0001] This utility model relates to the field of automatic connector assembly technology, and in particular to a locking and pressing mechanism. Background Technology

[0002] Fast charging (QC) connectors are important components in automobiles, and there are many types and large quantities of them. In their assembly process, the latch (or metal spring) is a common connecting element, which effectively prevents other parts inside the workpiece from loosening or falling out, and ensures that each part is fixed in the designated position.

[0003] Currently, although some automatic or semi-automatic pressing equipment exists, such as those using cylinders for direct pressing, most of these devices lack reliable guiding structures. This makes the locking mechanism prone to uneven stress during pressing, leading to deformation or jamming. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a locking and pressing mechanism.

[0005] The technical solution of this utility model is:

[0006] A locking and pressing mechanism includes a mounting bracket, characterized in that a lifting mechanism is provided on the mounting bracket, and a translation mechanism with the driving direction along the X direction is installed on the drive output end of the lifting mechanism.

[0007] A guide seat is installed on the drive output end of the translation mechanism. A feeding part and a pushing part are arranged sequentially on the guide seat along the X direction. The size of the feeding part is equivalent to the size of the latch, and the width of the pushing part is smaller than the width of the feeding part.

[0008] A push rod is slidably connected to the guide seat along the X direction. After the push rod pushes the latch from the feeding part into the feeding part, it pushes the guide seat out.

[0009] Furthermore, the lifting mechanism includes a lifting cylinder mounted on the mounting bracket, the drive output end of the lifting cylinder is fixedly connected to the lifting plate along the Z direction, and the translation mechanism is mounted on the lifting plate.

[0010] Furthermore, the translation mechanism includes a translation base plate and a first translation cylinder; the translation base plate is slidably connected to the lifting plate along the X direction, and the drive output end of the first translation cylinder is connected to the translation base plate along the X direction.

[0011] Furthermore, the guide seat includes a seat body and two seat side plates disposed opposite to each other on the seat body. Each seat side plate has a receiving flange protruding along its length direction on its inner side, and a guide groove is formed between the two receiving flanges. The space between the two seat side plates corresponding to the upper part of the guide groove forms the feeding part and the pushing part, respectively.

[0012] The push rod is slidably connected to the guide groove and is located at the end of the feeding section away from the pushing section.

[0013] Furthermore, the feeding section is used to place the latch, and its width is small at one end adjacent to the push rod and gradually increases at the other end;

[0014] The pusher section has a wider end adjacent to the discharge section and a gradually narrower end, which is used to cause the latch to undergo elastic deformation when it is squeezed by the pusher section when the push rod pushes the latch.

[0015] Furthermore, the two seat side plates corresponding to the pusher part extend outward from the outside of the seat body.

[0016] Furthermore, the top surfaces of the two seat side plates corresponding to the pushing part are jointly fixed to an upper limit plate, which covers the pushing part.

[0017] Furthermore, the seat body is fixed to the upper surface of the quick-change plate, and the quick-change plate is provided with a rotary lock;

[0018] A cam holder is provided on the upper surface of the translation base plate, and the locking end of the rotary lock can be engaged and locked in the cam holder.

[0019] Furthermore, a transition frame plate is connected to the translation base plate, and a second translation cylinder with a driving direction along the X direction is provided on the transition frame plate. The driving output end of the second translation cylinder is connected to the push rod in the direction of the material feeding section.

[0020] Furthermore, each of the side plates corresponding to the feeding section is provided with a notch; a photoelectric sensor for detecting whether there is a latch on the feeding section is installed at the notch.

[0021] The beneficial technical effects of this utility model are:

[0022] This invention, through the coordinated action of a lifting mechanism, a horizontal pushing mechanism, and a guiding pushing mechanism, achieves a fully automated process for smoothly pressing the latch onto the housing. The design of the guide seat ensures that the latching part of the latch can undergo smooth and controllable elastic deformation, effectively preventing misalignment or jamming during the pressing process.

[0023] In addition, the quick-change plate, through the cooperation of the rotary lock and the cam holder, enables quick assembly and disassembly with the sliding base plate, so as to quickly replace the guide seat with the appropriate one according to different models of locks, so as to be compatible with the press assembly of different products.

Detailed Implementation

[0033] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0034] This utility model provides a locking press-fitting mechanism for pressing a lock into a slot 001 on the housing 000.

[0035] This embodiment uses, as follows Figure 7 The latch 100 shown is for illustrative purposes only and is not intended to limit the specific shape of the latch. Figure 7 The lock 100 shown includes two rigid frame parts 101 and two elastically arranged opposite latching parts 102 connected between the two frame parts 101 and arranged opposite each other. The distance between the two latching parts 102 is greater than the length of the frame parts 101.

[0036] like Figures 1-6 As shown, the locking and pressing mechanism includes a mounting bracket 200, and a lifting mechanism is provided on the mounting bracket 200. The lifting mechanism includes a lifting cylinder 202 and a lifting plate 201 with the driving direction along the Z direction.

[0037] The fixed end of the lifting cylinder 202 is fixedly connected to the mounting bracket 200, and its drive output end passes through the mounting bracket 200 in the Z direction and is then fixedly connected to the lifting plate 201.

[0038] The lifting plate 201 is equipped with a translation mechanism 300 and a guide pushing mechanism 400.

[0039] The translation mechanism 300 includes a first push cylinder 301 with the driving direction along the X direction, a translation base plate 302, and a transition plate frame 303.

[0040] A slide rail (not shown) is fixedly provided on the upper surface of the lifting plate 201 along the X direction. A slider is slidably connected on the slide rail, and a translation base plate 302 is fixedly connected to the slider. The fixed end of the first horizontal thrust cylinder 301 is fixedly connected to the upper surface of the lifting plate 201. Its drive output end is along the X direction and connected to the translation base plate 302 in the direction of the housing 000, so as to drive the translation base plate 302 to move closer to or away from the housing 000 along the X direction.

[0041] Preferably, on the upper surface of the translation base plate 302, two mounting holes are symmetrically spaced at both ends along its length, and a cam holder 3021 is fixedly connected in each mounting hole for detachable connection with the rotary lock described below.

[0042] The transition plate frame 303 includes two parallel support arm plates 3031, with one end of each support arm plate 3031 connected by a fixing plate 3032. Each support arm plate is Z-shaped, with one end at a higher horizontal plane and the other at a lower horizontal plane. The fixing plate 3032 is connected to the higher end of the two support arm plates, while the lower ends of the two support arm plates are fixed to opposite sides of the translation base plate 302. The fixing plate 3032 is located on the side away from the housing 000, parallel to the translation base plate 302, and above the fixed end of the first horizontal push cylinder 301, so as to make reasonable use of space to install the guide push mechanism 400.

[0043] The guide push mechanism 400 includes a second flat push cylinder 401 with the driving direction along the X direction, a quick change plate 402, a guide seat 403, and a push rod 404 that is slidably connected in the guide seat 403 along the X direction.

[0044] To facilitate quick assembly and disassembly between the quick-change plate 402 and the sliding base plate 302, two mounting holes are symmetrically provided at both ends along the length of the quick-change plate 402. A rotary locking device 405 is installed in each mounting hole. The positions of the two rotary locking devices 405 correspond to the positions of the two upper cam holders 3021. The actuating end of each rotary locking device 405 engages with the corresponding cam holder 3021. Rotating the rotary locking device 405 in a preset direction allows the quick-change plate 402 to be detachably and stably connected to the upper surface of the sliding base plate 302. Both the rotary locking device 405 and the cam holder 3021 are commercially available components and represent existing technology.

[0045] The guide seat 403 is fixedly connected to the middle part of the quick-change plate 402. The guide seat 403 includes a seat body 4031. At one end of the upper surface of the seat body 4031, that is, on both opposite sides of the end near the housing, a side plate 4032 extends upward to form a side plate 4032. The length of the two side plates 4032 extends along the X direction and is parallel and symmetrically arranged. The end of each side plate near the housing extends out of the seat body, and the other end is located above the seat body 4031.

[0046] On the inner side of each of the two side plates 4032, at the midpoint along their length, a receiving flange 4033 protrudes towards each other. The two receiving flanges 4033 are parallel and opposite to each other, thereby forming a guide groove 4034 extending in the X direction between the two receiving flanges 4033. The end of the guide groove 4034 closer to the housing is defined as the outlet end, and the end farther from the housing is defined as the inlet end. The width of the groove at the outlet end and the inlet end is equivalent to the width of the slot 001 of the housing.

[0047] Based on the extension position of the guide groove, it can be divided into two functional sections: the inlet end of the guide groove is located above the seat body 4031, and the upper surface area of ​​the two bearing edges 4033 corresponding to this section is defined as the feeding section 4031a; the outlet end of the guide groove extends out of the seat side plate 4032 of the seat body, and the upper surface area of ​​the two bearing edges 4033 corresponding to this section is defined as the pushing section 4031b.

[0048] The distance between the two latching parts 102 of the latch 100 in its natural state is greater than the length of its frame part 101. In order to smoothly press the latch 100 into the slot of the housing, the two latching parts need to undergo elastic deformation and move closer to each other during the pressing process. After passing through the slot 001 and entering the housing, they rely on their own elasticity to reset and open, thereby achieving the latching.

[0049] Therefore, the distance between the two side plates 4032 corresponding to the feeding section 4031a (i.e., the width of the guide groove) is a contour-following design: the groove width at its entrance end is smaller, matching the length of the locking frame 101; from this entrance end towards the pushing section 4031b, the groove width gradually increases, matching the distance between the two latching parts 102 in the undeformed state; the feeding section 4031a is used to initially hold the locking buckle, and the locking frame 101 is placed towards its entrance end. In this embodiment, the feeding section 4031a is shown in a figure-eight shape.

[0050] The distance between the two side plates 4032 corresponding to the pusher section 4031b (i.e., the width of the guide groove) is a gradually narrowing design. From the end adjacent to the discharge section 4031a (where the groove width is larger) towards the outlet end, the groove width decreases uniformly and continuously. This design ensures that when the latch is pushed from the discharge section 4031a to the pusher section 4031b, its two latching parts 102 are smoothly compressed as the width of the guide groove gradually decreases, resulting in controllable elastic deformation. This allows the distance between the two to decrease smoothly until it can pass through the slot 001 of the housing, thereby completing precise press-fit guidance.

[0051] Preferably, to monitor in real time whether the latches on the feeding section 4031a are properly positioned, a notch 406 is provided on each of the two side plates 4032 corresponding to the feeding section 4031a, and the two notches are arranged opposite each other. A support rod 203 is fixedly provided on the lifting plate 201 at the position corresponding to each of the two notches, and a pair of photoelectric sensors 204 are installed on each support rod 203 to detect whether there are latches on the feeding section 4031a.

[0052] The fixed end of the second horizontal thrust cylinder 401 is fixed to the fixed plate 3032, and its drive output end faces the inlet end of the guide groove along the X direction and is connected to the push rod 404, thereby driving the push rod 404 to slide in the guide groove 4034 along the X direction. The push rod 404 is initially located on the side of the discharge section 4031a away from the housing. When the second horizontal thrust cylinder is running, the push rod 404 provides the required thrust for the latch to slide from the guide groove 4034 to the slot 001 of the housing.

[0053] like Figure 5 As shown, one end of the push rod 404 has a bayonet, through which it is detachably connected to the drive output end of the second horizontal push cylinder 401. The other end is a long rectangular handle. To further increase the stability of the push rod 404 during operation, a groove 4041 is formed along its length on each of the opposite sides of the handle of the push rod 404. The width of the groove 4041 is compatible with the width of the aforementioned receiving edge 4033. After assembly, each receiving edge 4033 slides and engages within the corresponding groove 4041. This structure effectively ensures the smoothness and accuracy of the push rod's linear movement along the X-axis.

[0054] Preferably, the top surfaces of the two side plates 4032 corresponding to the pusher part 4031b are jointly fixed with an upper limit plate 407. The upper limit plate 407 covers the pusher part 4031b, and its function is as follows: when the push rod 404 pushes the latch to slide from the release part 4031a to the pusher part 4031b, the latching part of the latch will be compressed and begin to undergo elastic deformation. The upper limit plate 407 can restrict the latching part of the latch from above, effectively preventing it from popping up upwards due to pressure, thereby ensuring that the latch smoothly and reliably enters the slot 001 in the elastic deformation state.

[0055] Preferably, in order to accurately control the stroke of the push rod 404, a limiting bolt 408 is provided on the side of the seat body 4031 facing the push rod. When the push rod pushes the latch from the feeding part to the feeding part and the housing, its locking part is exactly against the limiting bolt 408 to prevent excessive stroke.

[0056] The operation process of this utility model is as follows:

[0057] The housing 000 to be fitted with the locking buckle is placed on the carrier 500, and the locking buckle is placed on the feeding part 4031a. After the through-beam photoelectric sensor 204 detects that the locking buckle is in place, the lifting cylinder 202 drives the translation mechanism and the guide pushing mechanism to rise to the preset working position opposite to the carrier 500. Subsequently, the first horizontal pushing cylinder 301 drives the translation base plate 302 and the guide pushing mechanism 400 on the translation base plate to move towards the carrier 100 until the feeding part 4031b of the cantilever seat body is engaged with the interface 501 on the carrier 500. At this time, the slot 001 on the housing 000 is adjacent to and opposite the outlet end of the guide groove 4034. The second horizontal push cylinder 401 drives the push rod 404 to push the latch from the feeding part 4031a to the pushing part 4031b. At the same time, the two latching parts of the latch begin to elastically deform under the pressure of the seat side plates that gradually narrow on both sides of the pushing part, causing the distance between the two latching parts to gradually decrease. After deformation, the two latching parts continue to slide from the outlet end of the guide groove into the slot 001 on the housing 000. After reaching the preset position inside the housing, the external pressure on them disappears, and they open up by their own elasticity to achieve latching. The frame part 101 of the latch is latched into the slot 001. Thus, the latch pressing process is completed.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
