[0038] This embodiment provides a crimping device for assembling a diffuser plate and a lamp housing, such as Figure 3-10 As shown, it includes: a frame 1, and a lifting mechanism 2 and a pressing mechanism 3 installed on the frame 1; the lifting mechanism 2 includes a lifting plate 21 for supporting the lamp housing 100 and a lifting cylinder 22 for driving the lifting plate 21 to move between an upper position and a lower position, and a supporting portion 23 is provided around the lifting plate 21 for supporting the bottom of the buckle groove portion 101 on the lamp housing 100; when the lifting plate 21 is in the lower position, the pressing mechanism 3 cooperates with the supporting portion 23 to squeeze the buckle groove portion 101 to deform so as to clamp the diffuser 200.

[0039] When using the crimping device for crimping, the lifting cylinder 22 is initially controlled to drive the lifting plate 21 to rise to the upper position, the lamp housing 100 is placed on the lifting plate 21, and then the diffuser plate 200 is installed into the lamp housing 100 so that the edge of the diffuser plate 200 is stuck in the buckle groove 101 of the lamp housing 100 (or, the diffuser plate 200 is combined with the lamp housing 100 and then placed on the lifting plate 21), and then the lifting cylinder 22 drives the lifting plate 21 to descend to the lower position, and then the pressing mechanism 2 and the supporting part 23 cooperate to crimp so that the buckle groove 101 on the lamp housing 100 is deformed to clamp the diffuser plate 200, so that the diffuser plate 200 is reliably fixed on the lamp housing 100. After the crimping is completed, the pressing mechanism 3 removes the pressure on the lamp housing 100, and the lifting plate 21 is driven by the lifting cylinder 22 to rise to the upper position, and the crimped product is taken away.

[0040] See also Figures 4 to 9 As shown, the pressing mechanism 3 includes a rectangular frame-shaped upper support plate 31, a driving component 32 for driving the upper support plate 31 to move in the up and down directions, upper movable pressing plates 33 respectively arranged around the lower part of the upper support plate 31, a side thrust cylinder 34 for driving each upper movable pressing plate 33 to move lateral direction, and lower movable pressing plates 35 respectively arranged under each upper movable pressing plate 33, and each lower movable pressing plate 35 is provided with a pressure strip 351 on the inner side for pressing the upper part of the buckle groove portion 101 downward, that is, the buckle groove portion 101 is squeezed and deformed by cooperating with the pressure strip 351 and the support portion 23.

[0041] A cavity is formed in the middle of the upper support plate 31 for the lifting plate 21 to move up and down. A driving member is arranged at the lower part of the upper support plate 31 at a position corresponding to each lower movable pressing plate 35. Each lower movable pressing plate 35 can be mounted on the lower template 37 to be laterally movable. The lower template 37 can be mounted on the upper part of the fixed plate 38 to be elastically movable up and down through an elastic connecting member. The elastic connecting member provides an upward elastic force for the lower template 37. The fixed plate 38 is fixed to the frame 1. The upper movable pressing plate 33 is used to press the upper frame edge 102 of the lamp housing 100 downward. When the buckle groove 101 is pressed When connected, the upper frame 102 is pressed by the upper movable pressure plate 33 to keep the surface of the upper frame 102 flat; when the driving component 32 drives the upper support plate 31 to move downward, the driving component pushes the lower movable pressure plates 35 to move inward and pushes the lower template 37 to move downward; when the upper support plate 31 moves upward, the driving component successively releases the push on the lower template 37 and the lower movable pressure plate 35, and the lower template 37 moves upward under the elastic force of the elastic connecting member, and the lower movable pressure plate 35 moves outward under the elastic force of the elastic reset member.

[0042] Based on the above structure, when the lifting plate 21 is in the lower position, the lamp housing 100 placed thereon is correspondingly in a lower position (at this time, the bottom of the buckle groove portion 101 is against the support portion 23), and then the upper movable pressing plate 33 is driven to move inward to the top of the upper frame 102 by the side push cylinder 34, and then the upper support plate 31 is driven downward by the driving member 32. During this process, the driving member first pushes the lower movable pressing plate 35 to move inward so that the pressure strip 351 moves to the top of the buckle groove portion 101. As the upper support plate 31 continues to move downward, the driving member further pushes the lower template 37 to move downward (the lower movable pressing plate 35 moves downward with the lower template 37), and then the upper movable pressing plate 33 presses downward against the upper frame edge 102, and the pressure strip 351 presses downward against the buckle groove portion 101, so that the buckle groove part 101 is deformed by the pressure strip 351 cooperating with the support part to squeeze; after the crimping is completed, the upper support plate 31 moves upward under the drive of the driving member 32, and the driving member removes the pushing effect of the lower template 37 and the lower movable pressure plate 35 in succession, and the lower template 37 moves upward under the elastic force of the elastic connecting member, and then the lower movable pressure plate 35 moves outward under the elastic force of the elastic reset member, so that the pressure strip 351 is moved away from above the buckle groove part 101, and the side push cylinder 34 drives the upper movable pressure plate 33 to move outward to move the upper movable pressure plate 35 away from above the upper frame edge 102, so that when the lifting cylinder 22 drives the lifting plate 21 to move to the upward position, the lamp housing 100 will not be blocked by the pressure strip 351 and the upper movable pressure plate 35.

[0043] like Fig. 9 As shown, the upper part of the four sides of the lifting plate 21 is provided with an introduction block 210, and the support part 23 is set as the top surface of the introduction block 210. The introduction block 210 is a strip block arranged along the length direction of each corresponding edge of the lifting plate 21. A concave cavity for placing the lamp housing 100 is formed between all the introduction blocks 210, and the inner side of the introduction block 210 is set as a slope structure, which facilitates the lamp housing 100 to be quickly installed on the lifting plate 21, thereby ensuring the position accuracy and stability of the lamp housing 100, and further ensuring the crimping effect.

[0044] like Figure 6 As shown, the lifting cylinder 22 is fixed to the lower side of the fixed plate 38, and the telescopic end of the lifting cylinder 22 passes through the fixed plate 38 and is fixedly connected to the lifting plate 21. This design structure is compact.

[0045] The side thrust cylinder 34 is fixedly arranged on the lower side surface of the upper support plate 31, and the upper movable pressure plate 33 is connected to the telescopic end of the side thrust cylinder 34, so that the side thrust cylinder 34 drives the upper movable pressure plate 33 to move; a spring stopper 371 is fixedly arranged on the upper side surface of the lower template 37, and the elastic reset member is installed on the spring stopper 371 and connected to the lower movable pressure plate 35. When the driving member removes the inward thrust applied to the lower movable pressure plate 33, the lower movable pressure plate 33 can move outward under the elastic force of the elastic reset member.

[0046] like Fig.10 As shown, the driving member includes a vertical plug block 311 fixedly arranged at the lower part of the upper support plate 31, the spring stopper 371 is located below the vertical plug block 311, and an inclined push surface 312 is provided on the inner side of the vertical plug block 311. When the vertical plug block 311 moves downward with the upper support plate 31, it first pushes the lower movable pressing plate 35 to move inward through the inclined push surface 312, and then pushes the lower template 37 to move downward by resisting the spring stopper 371; that is, when the upper support plate 31 moves downward, the lower template 37 is pushed downward by the spring stopper 371. During the downward movement of 31, the side push surface 312 on the vertical plug block 311 first applies an inward thrust to the lower movable pressure plate 35, driving the lower movable pressure plate 35 to move inward, so that the pressure strip 351 moves to above the buckle groove portion, and then as the upper support plate 31 continues to move downward, the lower end of the vertical plug block 311 presses downward against the spring stopper 371, thereby pushing the lower template 37 and the lower movable pressure plate 35 thereon to move downward, and then the pressure strip 351 generates a downward pressure on the buckle groove portion 101.

[0047] Combination Fig. 9 and Fig.10 As shown, a slider seat 4 is fixedly provided at the bottom of the upper support plate 31 and the upper part of the lower template 37, respectively, a slider 5 is slidably provided on the slider seat 4, and the upper movable pressure plate 33 and each lower movable pressure plate 35 are fixedly connected to the slider 5 at the corresponding position, so that the upper movable pressure plate 33 and the lower movable pressure plate 35 are more flexible and smooth when they move inward and outward relative to the upper support plate 31 and the lower template 37 respectively.

[0048] For example, Fig.11 An elastic reset member structure is illustrated in the figure: the elastic reset member includes a limiting bolt 6, a gasket 7 and a helical compression spring 8, a bolt through hole extending along the movable direction of the corresponding lower movable pressure plate 35 is arranged on the spring stopper 371, the hole diameter of the bolt through hole is larger than the diameter of the limiting bolt 6, so that the limiting bolt 6 can move flexibly, the limiting bolt 6 is connected to the lower movable pressure plate 35 after passing through the bolt through hole, the helical compression spring 8 is sleeved on the limiting bolt 6, and the two ends are respectively against the spring stopper 371 and the gasket 7, so that the lower movable pressure plate 35 maintains a tendency to move outward.

[0049] In another example, a structure of an elastic connector is provided: it includes a strong spring and a connecting bolt arranged along the up and down directions, the strong spring is arranged between the lower template 37 and the fixed plate 38, the strong spring provides an upward rebound force for the lower template 37, the connecting bolt connects the lower template 37 with the fixed plate 38 and limits the up and down movable range of the lower template 37; optionally, the strong spring is arranged to be sleeved on the outer periphery of the connecting bolt; and in actual operation, the strong spring needs to provide sufficient elastic support for the lower template 37 to ensure that during the downward movement of the upper support plate, the downward component force generated by the vertical plug block pushing the lower movable pressure plate inward cannot cause the lower template 37 to move downward, so as to avoid interference with the side of the buckle groove when the lower movable pressure plate moves inward.

[0050] A limiting block 313 is fixed on the lower side of the upper supporting plate 31 between two adjacent upper movable pressing plates 33 , and the limiting block 313 plays a limiting role to prevent the upper movable supporting plate 31 from deviating during movement, thereby increasing stability during movement.

[0051] In some embodiments, a lower support plate 39 is provided below the fixed plate 38, and the upper support plate 31 and the lower support plate 39 are fixedly connected to form a moving whole through a support shaft 30, and the support shaft 30 can movably pass through the fixed plate 38; the driving component 32 is a telescopic cylinder fixed on the fixed plate 38, and the telescopic end of the telescopic cylinder is fixedly connected to the lower support plate 39, and multiple support shafts 30 can be provided to ensure the stability of the overall structure; the telescopic cylinder can be a pneumatic cylinder or a hydraulic cylinder.

[0052] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
