DETAILED DESCRIPTION

[0039] The following is a specific embodiment of the application and further describes the technical solutions of the present application in conjunction with the accompanying drawings, but the present application is not limited to these embodiments.

[0040] Embodiment One

[0041] As shown in FIG. 1, the flash assembly positioning device of the present application includes the bottom plate 1 and the floating plate 2 above the bottom plate 1, and the bottom plate 1 and the floating plate 2 are distributed in parallel. The floating plate 2 performs lifting motion in the vertical direction to achieve the purpose of approaching and moving away from the bottom plate 1. Figures 1-3 Secondly, as shown in FIGS. 2, 3,

[0042] Figure 1 Figure 4 Figure 5 and Figure 6 , the bottom plate 1 and the floating plate 2 are connected by the bidirectional motion correction assembly 3 distributed in the floating direction of the floating plate 2. The bidirectional motion correction assembly 3 is the upward and downward motion direction, and the bidirectional motion correction assembly 3 of the present embodiment is a mutually correcting assembly. Specifically, the bidirectional motion correction assembly 3 includes the first correction component 30 fixed on the floating plate 2, and the first correction hole 31 for the lower end of the first correction component 30 to insert is arranged on the bottom plate 1, and the lower end of the first correction component 30 and the first correction hole 31 are clearance fitted; the bidirectional motion correction assembly 3 further includes the second correction component 32 fixed on the floating plate 2, and the second correction hole 33 for the lower end of the second correction component 32 to insert is arranged on the bottom plate 1, and the lower end of the second correction component 32 and the second correction hole 33 are clearance fitted. ​​​

[0043] The lower end of the second correction component 32 is provided with an anti-dropping cap to play a limit position function, which is an inner hexagonal cap.

[0044] The bidirectional motion correction assembly 3 can form a limit position for the upward disengagement of the floating plate 2 and form a limit position for the downward motion.

[0045] The first correction component 30 corrects the motion direction of the floating plate 2, and the second correction component 32 on the floating plate 2 corrects again when the floating plate 2 moves. The bidirectional correction enables the floating plate 2 to accurately rise and fall in the vertical direction, so as to prevent the existence of deflection when guiding the vertical position of the flash lamp, and to realize the correction of the flash lamp in multiple dimensions perpendicular to the vertical direction, i.e., the X-axis and the Y-axis, and to ensure the accurate assembly of the flash lamp and the pressing plate.

[0046] In the preferred embodiment, the first correction component 30 has three, and two of the three first correction components 30 are fixed to the two corners of one end of the floating plate 2, and the remaining one first correction component 30 is fixed to the middle of the other end of the floating plate 2. The three first correction components 30 are distributed in an isosceles triangle. Secondly, the upper end of the first correction component 30 has a necked section 300, which is axially fixedly connected with the axial inner shoulder in the floating plate 2. The first correction component 30 includes a lower stepped shaft, a bolt is arranged at the upper end of the lower stepped shaft, the necked section 300 is formed between the uppermost section of the lower stepped shaft and the bolt, the lower stepped shaft and the bolt are threadedly connected, and the axial inner shoulder is clamped in the annular groove of the necked section 300.

[0047] The second correction component 32 has two, and the two second correction components 32 are distributed in the middle of the floating plate 2 in the width direction. The two second correction components 32 and the flash lamp positioning hole 20 are fixed to the floating plate 2 in an isosceles triangle. The two isosceles triangles are distributed in reverse, so that the floating plate 2 rises and falls in the vertical direction more smoothly and accurately.

[0048] And a vertical elastic assembly 4 is arranged between the bottom plate 1 and the floating plate 2. Specifically, the vertical elastic assembly 4 includes a plurality of vertically distributed springs, the upper end of the spring acts on the floating plate 2, and the lower end of the spring acts on the bottom plate 1. The spring of the embodiment has four and is arrayed.

[0049] The floating plate 2 is provided with a flash positioning hole 20 penetrating through the thickness direction of the floating plate 2, which is a profiling hole of the flash. The flash positioning hole 20 is provided with a clearance groove 200 at each of the four corners, so that the flash can be accurately positioned in the flash positioning hole 20. The bottom plate 1 is provided with a profiling vacuum adsorption head 5 extending into the flash positioning hole 20. The cross-sectional profile of the profiling vacuum adsorption head 5 is profiled to the flash positioning hole 20. During the lifting of the floating plate 2, the profiling vacuum adsorption head 5 can guide the floating plate 2 and continuously provide an adsorption force for the flash, so that the position consistency of the flash in the placement position and the adsorption state is ensured.

[0050] In the unassembled state, the top plane of the profiling vacuum adsorption head 5 is located below the upper hole of the flash positioning hole 20, so that the top plane of the profiling vacuum adsorption head 5 and the flash positioning hole 20 form a flash positioning groove. The floating plate 2 is further provided with a plurality of pressing plate circumferential positioning bosses 21 distributed around the flash positioning hole 20.

[0051] The flash to be assembled is placed in the flash positioning groove in advance;

[0052] The flash is adsorbed and fixed by the profiling vacuum adsorption head 5;

[0053] The floating plate 2 is lowered to a set position, and the flash is exposed at this time;

[0054] The pressing plate is placed in the interval enclosed by the pressing plate circumferential positioning bosses 21, and then the positioning hole on the pressing plate is matched and assembled with the corresponding position of the flash under the vertical pressure.

[0055] The pressing plate and the flash are concentrated on the same positioning floating plate, which can solve the poor accuracy of the pressing plate and the flash in different up-down mechanisms. The floating plate has multiple position states, the highest position is the flash placement state, the second highest position is the pre-pressing position of the pressing plate on the floating plate, and the third position is the assembly position of the floating plate lowered to the position (the pressing plate and the flash are assembled to the position). The above three positions are sequentially presented from top to bottom.

[0056] The flash positioning hole 20 and the pressing plate circumferential positioning boss 21 can be used as high-precision relative positions during processing, which ensures the positioning accuracy and precision. In combination with the bidirectional motion correction assembly 3, the flash positioning hole 20, the profiling vacuum adsorption head 5, and the pressing plate circumferential positioning boss 21, the floating plate 2 has high precision in different high positions, ensuring consistent high precision in different positions, and finally ensuring assembly precision.

[0057] In the highest position state, the flash can be corrected in multiple dimensions to ensure the consistency of the position before adsorption and fixation and the position after adsorption, thereby improving the subsequent assembly precision.

[0058] At the second-highest position, the pressure plate can be circumferentially positioned, and the mounting holes on the pressure plate and the flash lamp can be aligned. Since the same floating plate is used to position different parts, it can prevent the phenomenon of decreased assembly accuracy due to unavoidable errors in alignment when different mechanisms are positioned and assembled.

[0059] When assembled into the correct position, the floating plate 2 serves to position the device, while the pressure plate assembles with the flash to achieve the set position precision.

[0060] Secondly, such as Figures 1-3 As shown, in this embodiment, the flash positioning hole 20 is located between two circumferential positioning bosses 21 of the pressure plates distributed in the width direction of the floating plate 2. These two circumferential positioning bosses 21 of the pressure plates form symmetrical guides on opposite sides of the pressure plates, which allows for precise and balanced assembly of the flash and the pressure plates at a balanced force distribution in the middle position.

[0061] The top surface of the floating plate 2 is provided with a bottom positioning protrusion 22 of the pressure plate located in the space enclosed by the circumferential positioning protrusion 21 of the pressure plate. The bottom positioning protrusion 22 of the pressure plate is shaped to resemble the bottom surface structure of the pressure plate to further improve the assembly accuracy. The upper end of the flash lamp positioning hole 20 passes through the bottom positioning protrusion 22 of the pressure plate.

[0062] In addition, two opposing clearance grooves 23 are provided on the top surface of the floating plate 2. Each clearance groove 23 is located between two circumferential positioning bosses 21 of the pressure plate along the length of the floating plate 2. The clearance grooves 23 are for the entry clearance of the pressure plate clamping mechanism to prevent the pressure plate clamping mechanism from contacting and colliding with the floating plate 2, which could lead to decreased accuracy, mutual wear and shortened service life, etc.

[0063] like Figure 8 As shown, a conical surface is provided on the inner wall of the upper end of the vertical adsorption hole of the contour vacuum adsorption head 5, and an inverted conical cylinder 50 is fixed on the conical surface. The upper end face of the inverted conical cylinder 50 is flush with the top surface of the contour vacuum adsorption head 5. Several inclined grooves 51 are provided on the conical surface in a circumferentially evenly distributed manner. The inclined grooves 51 and the outer wall of the inverted conical cylinder 50 form a through hole. The lower end of the inclined grooves 51 is connected to the vertical adsorption hole, and the upper end of the inclined grooves 51 is connected to the outside.

[0064] The inverted conical cylinder 50 is made of silicone material. The inner diameter of the inverted conical cylinder 50 gradually increases from top to bottom, presenting a structure opposite to the outer diameter of the outer wall of the inverted conical cylinder 50.

[0065] The inverted conical cylinder 50 is fixed to the conical surface by means of adhesive or screws.

[0066] When adsorbing, the vertical adsorption holes are vacuumed downward, at this time, the lower surface inner circle of the flash lamp and the upper end surface of the inverted conical cylinder 50 are matched and sealed, and the inclined groove 51 is also vacuumed, so that the lower surface of the flash lamp is adsorbed in multiple positions, ensuring the stability of the flash lamp fixation.

[0067] Embodiment two

[0068] As Figures 1-7 shown, the embodiment provides a flash lamp assembling method, which adopts the flash lamp assembling positioning device of embodiment one, and comprises the following steps:

[0069] S1, a flash lamp positioning groove is formed between the upper aperture of the flash lamp positioning hole 20 of the floating plate 2 and the top surface of the profiling vacuum adsorption head 5, the flash lamp is placed in the flash lamp positioning groove, and the flash lamp is adsorbed by the profiling vacuum adsorption head 5;

[0070] S2, the floating plate 2 in S1 is lowered so that the flash lamp is exposed, and the floating plate 2 is lowered to a pre-pressing position of the pressing plate;

[0071] S3, the pressing plate is placed in the space surrounded by the circumferential positioning boss 21 of the floating plate 2 in S2, the pressing plate is assembled with the positioning hole on the pressing plate under the action of vertical pressure, and when the floating plate 2 is lowered to a pressing plate assembly position, the assembly of the pressing plate and the flash lamp is completed;

[0072] S4, the floating plate 2 in S3 is reset, and the profiling vacuum adsorption head 5 is de-adsorbed, so that the combination of the flash lamp and the pressing plate is separated from the profiling vacuum adsorption head 5, that is, the assembly is completed.
