[0034] Moreover, the technical solutions between various embodiments of the present invention can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it.

[0035] The present invention provides a film pasting tooling fixture 1, as Figures 1 to 7 shown. In one embodiment, the film pasting tooling fixture 1 is used to clamp a convex workpiece 2. The film pasting tooling fixture 1 includes a clamping device 11. The clamping device 11 includes at least two clamping members 112 and a driving mechanism 111. The driving mechanism 111 is in transmission connection with each clamping member 112. The inner wall of the clamping member 112 is used to abut against the side wall of the convex workpiece 2, so that the driving mechanism 111 can drive each clamping member 112 to clamp or release the convex workpiece 2. A first guiding wall 1121 is provided on the top surface of each clamping member 112. The first guiding wall 1121 is used to extend along the circumferential direction of the convex workpiece 2. One end of the first guiding wall 1121 close to the convex workpiece 2 is higher than the end of the first guiding wall 1121 far from the convex workpiece 2. The top 11211 of the first guiding wall is used to abut against the edge of the top surface 21 of the convex workpiece 2, so that the film material 3 can smoothly transition from the edge of the convex workpiece 2 to the first guiding wall 1121 during the film pasting process.

[0036] Among them, the driving mechanism 111 drives each clamping member 112 to clamp the convex workpiece 2. The inner wall of each clamping member 112 abuts tightly against the side wall of the convex workpiece 2. The inner wall of the clamping member 112 refers to the side wall on the side of the clamping member 112 facing the convex workpiece 2. The film pasting device gradually extends and pastes the film material 3 from the center of the convex workpiece 2 to the periphery. When the film material 3 extends to the edge of the convex workpiece 2, due to the first guiding wall 1121 abutting against the edge of the top surface 21 of the convex workpiece 2, the film material 3 will continue to extend obliquely downward, so that the film material 3 can smoothly transition from the edge of the convex workpiece 2 to the first guiding wall 1121. The film material 3 will continue to extend along the first guiding wall 1121. And the first guiding wall 1121 extends along the circumferential direction of the convex workpiece 2, so that the film material 3 near the edge of the convex workpiece 2 is not likely to have appearance quality problems, improving the quality of film pasting on the convex workpiece 2. It should be noted that, as Figure 6As shown, there can be multiple clamping members 112. The multiple clamping members 112 are arranged in sequence along the circumferential direction of the convex workpiece 2. The first guiding walls 1121 of the multiple clamping members 112 can be joined together to form a complete guiding surface, so as to better guide the film material 3 and reduce the phenomenon of appearance quality problems of the film material 3 near the edge of the convex workpiece 2. It should also be noted that the axial direction of the convex workpiece 2 is Figure 1 the up and down direction shown in the figure. The convex workpiece 2 bulges upward. One end of the first guiding wall 1121 close to the convex workpiece 2 is located above the end of the first guiding wall 1121 far from the convex workpiece 2.

[0037] According to an embodiment of the present invention, the driving mechanism 111 includes a driving component, a mounting table, a connecting wire, and a return spring. At least two clamping members 112 are all slidably engaged with the mounting table. The clamping member 112 includes a clamping position and an initial position. When the clamping member 112 is at the clamping position, the clamping member 112 clamps the convex workpiece 2. When the clamping member 112 is at the initial position, the clamping member 112 releases the convex workpiece 2; the number of return springs is the same as that of the clamping members 112 and they are arranged in one-to-one correspondence. One end of the return spring is connected to the clamping member 112, and the other end of the return spring is connected to the mounting table. The return spring is used to drive the clamping member 112 to move from the clamping position to the initial position. The number of connecting wires is the same as that of the clamping members 112 and they are arranged in one-to-one correspondence. One end of the connecting wire is connected to the clamping member 112, and the other end of the connecting wire is connected to the telescopic shaft of the driving component. When the telescopic shaft of the driving component contracts downward, the telescopic shaft drives the clamping member 112 to move from the initial position to the clamping position through the connecting wire, and the return spring is compressed under force; when the telescopic shaft of the driving component extends upward, the clamping member 112 moves from the clamping position to the initial position under the elastic force of the return spring, so as to realize that one driving component can drive at least two clamping members 112 to clamp or release the convex workpiece 2.

[0038] Such as Figure 1 、 Figure 3 、 Figure 4 and Figure 7As shown, in one embodiment, a groove 1124 is provided on the top surface of each clamping member 112. The groove wall of the groove 1124 includes a first guiding wall 1121 and a second guiding wall 1122 that are connected to each other. The first guiding wall 1121 is used to be arranged close to the convex workpiece 2, and the concave direction of the groove 1124 is arranged opposite to the protruding direction of the convex workpiece 2. Among them, when the film material 3 extends to the edge of the convex workpiece 2, if the film material 3 continues to extend, it will fit with the first guiding wall 1121. Since the groove 1124 is recessed downward and the convex workpiece 2 protrudes upward, therefore, under the action of the first guiding wall 1121, the film material 3 will continue to extend obliquely downward. Since the film material 3 has a smooth transition from the convex workpiece 2 to the first guiding wall 1121, and the first guiding wall 1121 is used to guide the film material 3 to continue to move obliquely downward, the film material 3 attached near the edge of the convex workpiece 2 is not likely to have appearance quality problems.

[0039] Among them, in one embodiment, the first guiding wall 1121 includes a wall body 11211 and a transition wall 11212 that are connected to each other. The inner wall of the clamping member 112 protrudes toward the direction where the convex workpiece 2 is located to form a positioning rib 1126. The positioning rib 1126 is used to abut against the side wall of the convex workpiece 2. The top surface of the positioning rib 1126 is the transition wall 11212, and the transition wall 11212 is used to abut against the edge of the top surface 21 of the convex workpiece 2. When it is necessary to clamp the convex workpiece 2, the driving mechanism 111 drives the clamping member 112 to move toward the direction close to the convex workpiece 2 so that the positioning rib 1126 abuts tightly against the side wall of the convex workpiece 2. Since the positioning rib 1126 is formed by the inner wall of the clamping member 112 protruding toward the direction where the convex workpiece 2 is located, when the positioning rib 1126 abuts tightly against the side wall of the convex workpiece 2, a gap is formed between the inner wall of the clamping member 112 without the positioning rib 1126 and the side wall of the convex workpiece 2; when the film material 3 extends to the edge of the convex workpiece 2 and continues to extend, part of the film material 3 will be smoothly transitioned to the wall body 11211 under the guidance of the transition wall 11212, and the rest of the film material 3 will first pass through the gap and then extend to the wall body 11211. The film material 3 passing through the gap will extend downward or obliquely downward, so that the film material 3 attached near the edge of the convex workpiece 2 in this part is not likely to have appearance quality problems.

[0040] Furthermore, in one embodiment, the first guide wall 1121 and the second guide wall 1122 are both inclined surfaces, the inner wall of the clamping member 112 is connected to the top 11211 of the first guide wall, and the inner wall of the clamping member 112 is used to fit with the side wall of the convex workpiece 2 so that the top 11211 of the first guide wall can abut against the edge of the top surface 21 of the convex workpiece. When the convex workpiece 2 needs to be clamped, the driving mechanism 111 drives the clamping member 112 to move towards the direction close to the convex workpiece 2, so that the inner wall of the clamping member 112 is attached to and pressed against the side wall of the convex workpiece 2. Since the inner wall of the clamping member 112 is connected to the top 11211 of the first guide wall, and the first guide wall 1121 extends along the circumferential direction of the convex workpiece 2, when the film material 3 extends to the edge of the convex workpiece 2, the film material 3 continues to extend, and the film material 3 extending outward will contact the first guide wall 1121 and continue to extend in the oblique downward direction under the guidance of the first guide wall 1121, so that the film material 3 attached near the edge of the convex workpiece 2 is not prone to appearance quality problems.

[0041] In addition, in one embodiment, the end of the first guide wall 1121 connected to the second guide wall 1122 is used to be inclined in a direction away from the protrusion of the convex workpiece 2, and the end of the second guide wall 1122 away from the connection with the first guide wall 1121 is used to be inclined in a direction of the protrusion of the convex workpiece 2. Since the groove 1124 is concave downward, the end of the first guide wall 1121 close to the second guide wall 1122 is inclined downward, and the end of the second guide wall 1122 away from the first guide wall 1121 is inclined upward. It should be noted that the second guide wall 1122 can also be set obliquely downward.

[0042] Furthermore, in one embodiment, a curved transition surface 1123 is provided at the connection between the first guide wall 1121 and the second guide wall 1122. By providing the curved transition surface 1123, the film material 3 can smoothly transition from the first guide wall 1121 to the second guide wall 1122.

[0043] like Figures 1 to 4 As shown, in one embodiment, the driving mechanism 111 includes a plurality of driving components, the number of driving components is the same as that of the clamping members 112, and they are arranged one by one. The driving components are in transmission connection with the clamping members 112, so that the driving components can drive the clamping members 112 to approach or move away from the convex workpiece 2, so that the driving mechanism 111 can drive each clamping member 112 to clamp or release the convex workpiece 2. The driving components are arranged one by one with the clamping members 112, so that the motion state of each clamping member 112 is independently controlled by the driving components arranged corresponding thereto.

[0044] Among them, in one embodiment, the film attaching tooling fixture 1 further includes a mounting base 12. Each clamping member 112 is slidably engaged with the mounting base 12. The driving assembly is used to drive the clamping member 112 to reciprocally slide relative to the mounting base 12, so that the clamping member 112 approaches or moves away from the convex workpiece 2. The clamping member 112 is slidably engaged with the mounting base 12 so that the clamping member 112 can move along a preset direction. It should be noted that the clamping member 112 is provided with a chute, and the mounting base 12 is provided with a slide rail slidably engaged with the chute.

[0045] Moreover, in one embodiment, the driving assembly includes a driving member and a transmission member 1113 that are drivingly connected. The transmission member 1113 is slidably engaged with the mounting base 12, so that the driving member can drive the transmission member 1113 to reciprocally slide relative to the mounting base 12. The transmission member 1113 is also drivingly connected to the clamping member 112, so that the driving member can drive the clamping member 112 to approach or move away from the convex workpiece 2 through the transmission member 1113. The driving member drives the transmission member 1113 to slide relative to the mounting base 12, thereby driving the transmission member 1113 to move, and then driving the clamping member 112 to move through the transmission member 1113, so that the clamping member 112 can clamp or release the convex workpiece 2.

[0046] According to an embodiment of the present invention, the transmission member 1113 is a rack. The driving assembly further includes a transmission component, which includes a rotating rod and a first gear and a second gear arranged in sequence along the extending direction of the rotating rod. The rotating rod is vertically arranged and rotatably connected to the mounting base 12. The first gear is engaged with the rack. A plurality of meshing teeth are arranged in sequence along the movement direction of the clamping member 112. The second gear is engaged with the meshing teeth, so that the driving member drives the rack to move. The rack drives the second gear to rotate through the first gear and the rotating rod. Since the second gear is engaged with the meshing teeth, the rotating second gear can drive the clamping member 112 to move, so that the driving member can drive the clamping member 112 to approach or move away from the convex workpiece 2.

[0047] Furthermore, in one embodiment, the transmission member 1113 includes a sliding portion 1114 and a guiding portion 1115 that are connected to each other. The sliding portion 1114 is slidably engaged with the mounting base 12. A guiding groove 1127 is formed on one side of the clamping member 112 facing the guiding portion 1115. The guiding portion 1115 is located in the guiding groove 1127 and is slidably engaged with the guiding groove 1127. The driving member is drivingly connected to the sliding portion 1114. The driving member is used to drive the guiding portion 1115 to reciprocally slide in the guiding groove 1127 through the sliding portion 1114, so that the guiding portion 1115 can drive the clamping member 112 to approach or move away from the convex workpiece 2 under the guidance of the guiding groove 1127. The driving member drives the guiding portion 1115 to slide in the guiding groove 1127 through the sliding portion 1114. Under the guidance of the guiding groove 1127, the guiding portion 1115 can drive the clamping member 112 to approach or move away from the convex workpiece 2.

[0048] Furthermore, in one embodiment, the driving member includes a driving body 1111 and an elastic reset member 1112, the driving body 1111 is transmission-connected to the transmission member 1113, the two ends of the elastic reset member 1112 are respectively connected to the mounting seat 12 and the transmission member 1113, the transmission member 1113 includes a starting position and a clamping position, when the transmission member 1113 is in the starting position, the clamping member 112 releases the convex workpiece 2, when the transmission member 1113 is in the clamping position, the clamping member 112 clamps the convex workpiece 2, the driving body 1111 is used to drive the transmission member 1113 to move from the starting position to the clamping position, and the elastic reset member 1112 is used to drive the transmission member 1113 to move from the clamping position to the starting position. The driving body 1111 may be a cylinder or a telescopic ejector pin, etc. When the convex workpiece 2 is placed in the discharge area provided on the top of the mounting seat 12, the telescopic shaft of the driving body 1111 extends to drive the sliding part 1114 to slide relative to the mounting seat 12. At this time, the elastic reset member 1112 is stretched, and the sliding part 1114 drives the guide part 1115 to slide in the guide groove 1127, thereby driving the clamping member 112 to move toward the convex workpiece 2 until it is pressed against the side wall of the convex workpiece 2. When multiple clamping members 112 complete the pressing process together, the clamping of the convex workpiece 2 is completed; when the convex workpiece 2 needs to be released, the telescopic shaft of the driving body 1111 is retracted, and the sliding part 1114 is reset under the elastic force of the elastic reset member 1112, and the clamping member 112 is driven to reset through the transmission part, thereby releasing the clamping of the convex workpiece 2. The elastic reset member 1112 may be a spring.

[0049] In addition, in one embodiment, the end of the clamping member 112 is used to abut against the end of an adjacent clamping member 112. When each clamping member 112 clamps the convex workpiece 2, the ends of any two adjacent clamping members 112 abut against each other, and any two adjacent first guide walls 1121 are butted against each other. The ends of any two adjacent clamping members 112 abut against each other, so that the first guide wall 1121 can be arranged around the convex workpiece 2, thereby better preventing quality problems from occurring when the convex workpiece 2 is filmed.

[0050] In addition, if Figures 1 to 7 As shown, the present invention further provides a film pasting device, which includes a film pasting device, a convex workpiece 2 and the above-mentioned film pasting fixture 1, and the film pasting device is used to paste the film material 3 on the top surface 21 of the convex workpiece clamped by the clamping member 112. Since the film pasting device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.
