[0030] For the convenience of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The typical embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. Without conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0031] Refer to Figure 1-2 , the curved surface glass concave surface gluing auxiliary fixture of this embodiment includes a pressing-down module 1, a light-curing base 2 and a movable positioning module 3.

[0032] Among them, the top of the light-curing base 2 is open and the inside is hollow, and a curing lamp for curing the glue on the concave surface of the glass is installed. For example, in this embodiment, the light-curing base 2 is a rectangular box body with an open top. For example, if the glue is resin glue, the curing lamp can be a UV curing lamp to perform UV curing on the resin glue. The material of the light-curing base 2 is an opaque and non-reflective material, which can reduce the harm to the eyesight of personnel.

[0033] Among them, the top of the movable positioning module 3 is used to position and place the glass 4 with the concave surface facing up. The movable positioning module 3 is generally in the shape of a rectangular body, and the center of its top is recessed. This recess is in a shape-matching fit with the reverse side of the concave surface of the glass 4, and the glass 4 is placed in this recess. A circular groove is provided at the edge of the middle recess on the top of the movable positioning module 3, and the edge of the glass 4 is placed on this circular groove. The movable positioning module 3 is movably positioned above the light-curing base 2 and seals the open mouth at the top of the light-curing base 2, and the concave surface of the glass 4 is directly above the open mouth at the top of the light-curing base 2 to cure the glue using the curing lamp. Since it is necessary to use the UV curing lamp below to perform UV curing on the glue on the concave surface of the glass 4, the material of the movable positioning module 3 is a transparent material, such as high-transparency materials like PMMA or PC. Black adhesive tape can also be pasted around the movable positioning module 3 to further reduce the harm to the eyesight of personnel.

[0034] Among them, the pressing-down module 1 mainly includes a lifting mechanism 12 installed on the light-curing base 2 and a shape-matching pressing-down component 11 located above the movable positioning module 3 and moving up and down under the drive of the lifting mechanism 12. The shape-matching pressing-down component 11 provides a shape-matching pressing-down surface imitating the concave surface shape of the glass for shape-matching cooperation with the concave surface of the glass when the shape-matching pressing-down component 11 is pressed down to the low position.

[0035] The following combines the attached Figure 3 、 4 , and further elaborates on the pressing-down module 1 in detail.

[0036] The pressing-down module 1 includes a shape-matching pressing-down component 11, a lifting mechanism 12, an upper fixing plate 13, multiple support columns 14, a bottom plate 15, a positioning pin 16, a linear bearing 17, and a buffer spring 18.

[0037] The upper fixing plate 13 is a horizontally arranged rectangular plate, and the support columns 14 are vertically arranged cylinders. The lower end of the support column 14 is connected to the bottom plate 15, and the upper end of the support column 14 is connected to the upper fixing plate 13. The upper fixing plate 13 is installed above the light curing base 2 through the plurality of support columns 14. The purpose of the support columns 14 is to leave enough space for convenient and quick picking and placing of the movable positioning module 3. Specifically, in this embodiment, there are four support columns 14 in particular, and the four support columns 14 support the four corner positions of the upper fixing plate 13. The upper end of the support column 14 is processed into a rectangle, and rectangular grooves are opened at the four corner positions of the bottom of the upper fixing plate 13. The upper end of the support column 14 is positioned in the rectangular groove, and then the support column 14 is locked from the top of the upper fixing plate 13 with screws. The bottom plate 15 is a horizontally arranged annular plate, specifically a rectangular ring, which is composed of four side plates in the front, back, left and right. The width of the side plate is slightly larger than the thickness of the four side walls of the light curing base. The lower end of the support column 14 is also processed into a rectangle. Four positioning grooves 152 are arranged at the positions near the four corners of the bottom plate 15. The positioning groove 152 is a rectangular groove. The lower end of the support column 14 is positioned in the rectangular groove, and then the support column 14 is locked from the bottom of the bottom plate 15 with screws. The overall combination of the bottom plate 15 and the support column 14 after being locked is fixedly installed on the top of the light curing base 2. Specifically, a plurality of through holes 151 are opened on the four side plates in the front, back, left and right of the bottom plate 15, and a corresponding plurality of mounting holes 21 are opened on the top edges of the four side walls of the light curing base. Screws pass through the through holes 151 and the mounting holes 21 to fix the bottom plate 15 to the top of the light curing base.

[0038] Further, two pin holes are also opened on the front and rear side plates of the bottom plate 15 for installing two positioning pins 16. The two pin holes are located inside the circle of through holes 151. The movable positioning module 3 is positioned and placed on the bottom plate 15 through the positioning pins 16 and blocks the open top of the box body.

[0039] Among them, the lifting mechanism 12 is a spinning mechanism, which is fixedly installed on the top of the upper fixing plate 13 and is used to convert rotational motion into smooth downward pressing motion. The profiling downward pressing component 11 is located among the plurality of support columns 14 and below the upper fixing plate 13, and passes through the upper fixing plate 13 and is connected to the lifting mechanism 12. The length / width dimension of the movable positioning module 3 is smaller than the distance between the two support columns 14 so as to be picked and placed from between the two support columns 14.

[0040] Specifically, the profiling downward pressing component 11 includes a profiling push head 111 with the profiling downward pressing surface at the bottom, a plurality of guide rods 112, a plurality of fasteners 115 corresponding to the plurality of guide rods 112, a push rod 113, and a thrust bearing 114. The spinning mechanism includes a spinning rod 121, a limit pulling handle 122, a coupling pin 123, an anti - detachment hanging platform 124, and an assisting rod 125.

[0041] A plurality of linear bearings 17 corresponding to the plurality of guide rods 112 are mounted on the upper fixing plate 13 , and the guide rods 112 pass through the upper fixing plate 13 via the corresponding linear bearings 17 . The push rod 113 movably passes through the upper fixing plate 13 .

[0042] The upper end of the guide rod 112 is connected to the limit handle 122. Specifically, the upper end of the guide rod 112 is processed into a rectangular shape, and the limit handle 122 is a horizontally arranged rectangular plate with rectangular grooves at the bottom of the rectangular plate near the two short sides. The upper end of the guide rod 112 is positioned in the rectangular groove, and then the guide rod 112 is locked with screws from the top of the limit handle 122. The connection method of this part refers to the locking method of the upper and lower ends of the support column 14.

[0043] The lower end of the guide rod 112 is connected to the top of the contoured push head 111. Specifically, the fastener 115 of the fastener 115 is a rectangular block. The four corners of the fastener 115 are screwed to the top of the contoured push head 111. A through hole matching the guide rod 112 is provided in the middle of the fastener 115. The guide rod 112 passes through the through hole. The portion of the lower end of the guide rod 112 extending from the fastener 115 is slightly enlarged to form a large head. A guide rod positioning hole 1112 matching the large end of the guide rod 112 is provided at the top of the contoured push head 111. In this way, the large end of the guide rod 112 is held against the fastener 115, thereby achieving the upper and lower fastening connection between the guide rod 112 and the fastener 115. Therefore, the guide rod 112 cannot fall off.

[0044] The lower end of the push rod 113 is connected to the top of the contoured push head 111. Specifically, the top of the contoured push head 111 is provided with a push rod mounting hole 1111 for mounting a thrust bearing 114. The lower end of the push rod 113 is connected to the thrust bearing 114. Two fasteners 115 are located on either side of the push rod mounting hole 1111. These fasteners 115 partially cover the push rod mounting hole 1111 to press the thrust bearing 114, preventing the push rod 113 from falling off.

[0045] The upper end of the push rod 113 is connected to the lower end of the spinning rod 121. Specifically, two plate-shaped connecting ears are machined on the upper end of the push rod 113, and a plate-shaped connecting ear is machined in the center of the lower end of the spinning rod 121. The connecting ear of the spinning rod 121 is inserted between the two connecting ears of the push rod 113, and the three connecting ears are connected together by a coupling pin 123.

[0046] The assisting rod 125 can be used to rotate the spinning rod 121. Specifically, the assisting rod 125 is perpendicular to the spinning rod 121 and passes through a through-hole at the upper end of the spinning rod 121 with a radial dimension matching that of the assisting rod 125. Anti-disengagement hanging platforms 124 are coaxially installed at both ends of the assisting rod 125, and the radial dimension of the anti-disengagement hanging platform 124 is larger than that of the assisting rod 125, thereby preventing the spinning rod 121 from disengaging from the upper end of the spinning rod 121.

[0047] A buffer spring 18 is also sleeved outside the guide rod 112, and the buffer spring 18 is located on the linear bearing 17. Under the free state, the gravity of the profiling push head 111 drives the limit pull handle 122 to drop onto the buffer spring 18.

[0048] A first threaded hole 1221 is formed in the center of the limit pull handle 122, and the spinning rod 121 passes through the first threaded hole 1221. Except for the upper end and the lower end, external threads matching the first threaded hole 1221 are provided on the entire axial side wall of the middle main body portion of the spinning rod 121, so as to be lifted and lowered by rotation.

[0049] A second threaded hole 131 is formed in the center of the upper fixing plate 13, and the push rod 113 movably passes through the second threaded hole 131. A small section of thread matching the second threaded hole 131 is provided at a position near the lower end of the push rod 113. When the movable positioning module 3 needs to be taken or placed, the push rod 113 is lifted to be in threaded cooperation with the second threaded hole 131, thereby fixing the profiling push head 111 at a high position, which is convenient for loading or unloading the movable positioning module 3.

[0050] When applying glue, first pour the glue onto the concave surface of the glass 4, and then manually rotate the assisting rod 125 to make the profiling push head 111 descend until the profiling push head 111 stops rotating when obvious resistance is received. Since the profiling surface of the profiling push head 111 pushes the glue, the glue is uniformly coated on the concave surface of the glass with a uniform thickness. Then, turn on the curing lamp to cure the glue. After curing, manually rotate the assisting rod 125 to make the profiling push head 111 ascend.

[0051] In this embodiment, the operator only needs to rotate the spinning rod 121 through the assisting rod 125 to raise or lower the spinning rod 121. The buffer spring provides buffering when the profiling pressing component 11 falls rapidly or presses down slowly, preventing damage to the components. The linear bearing 17 can ensure the smooth rising and falling of the pressing component 11 and has the function of auxiliary positioning. Since the spinning rod 121 and the push rod 113 are connected by a coupling pin 123, and a thrust bearing 114 is added between the push rod 113 and the profiling push head 111 to offset the friction between rotation and components, both the guide rod 112 and the thrust bearing 114 are tightened by fasteners 115 to prevent detachment during upward movement. In this way, the profiling push head 111 moves smoothly and is easy to operate, and there will be no rotation, dislocation and other states.
