[0092] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0093] The present application provides a fixture, which includes a bearing plate, a first limiting component, and a second limiting component. A first groove is formed on one side of the bearing plate, and the shape of the first groove matches the workpiece to be clamped to accommodate a first part of the workpiece; the first limiting component is arranged on the bearing plate, and a part of it is selectively used to abut against a second part of the workpiece exposed from the first groove on the side of the first groove; the second limiting component is arranged on the bearing plate, and a part of it is selectively used to abut against a third part of the workpiece exposed from the first groove on the side of the first groove; wherein, at least partial components of the forces applied by the first limiting component, the second limiting component, and the first groove to the workpiece are coplanar, and the included angle between any two of them is less than 180 degrees.

[0094] The present application further provides an assembly device, which includes the above-mentioned fixture and a flipping device, and the flipping device is used to drive the fixture to rotate by a certain angle.

[0095] The fixture and the assembly device provided by the present application will be described in detail below with reference to the embodiments.

[0096] Please refer to Figure 1 , Figure 1 which is a three-dimensional structural schematic diagram of the workpiece to be clamped in the fixture embodiment of the present application.

[0097] As Figure 1 described, the workpiece 10 is in the shape of a hemispherical shell, and its cavity is used to accommodate components. The fixture of the present application is used to clamp the workpiece 10, so as to facilitate the assembly of components in its cavity. For the convenience of describing the clamping position, different parts of the workpiece 10 are named as follows: the central area of the outer wall surface is the first part 11, the edge is the second part 12, and the area between the first part 11 and the second part 12 on the outer wall surface is the third part 13.

[0098] Please refer to Figures 2 to 4 , Figure 2 which is a structural schematic diagram of the fixture embodiment of the present application, Figure 3 is Figure 2 the bottom view of Figure 4 is Figure 2 the left view of

[0099] As Figures 2 to 4As shown in the figure, an embodiment of the present application provides a fixture 100, which includes a carrier plate 110, a first limiting component 120, and a second limiting component 130. A first groove 111 is formed on one side of the carrier plate 110, and the shape of the first groove 111 matches that of the workpiece 10 to be clamped, so as to accommodate the first part 11 of the workpiece 10; the first limiting component 120 is arranged on the carrier plate 110, and a part of it is used to selectively abut against the second part 12 of the workpiece 10 exposed outside the first groove 111 on the side of the first groove 111; the second limiting component 130 is arranged on the carrier plate 110, and a part of it is used to selectively abut against the third part 13 of the workpiece 10 exposed outside the first groove 111 on the side of the first groove 111; wherein, at least partial components of the forces applied by the first limiting component 120, the second limiting component 130, and the first groove 111 to the workpiece 10 are coplanar, and the angle between any two of them is less than 180 degrees.

[0100] Please refer to Figure 5 , Figure 5 which is a schematic diagram of the force structure of the workpiece in the clamped state in the fixture embodiment of the present application.

[0101] As Figure 5 shown, at least partial components F1, F2, and F3 of the forces applied by the first limiting component 120, the second limiting component 130, and the first groove 111 to the workpiece 10 are located in the same plane, and the angles θ1, θ2, and θ3 between any two of them are all less than 180 degrees.

[0102] During use, first place the workpiece 10 in the first groove 111, and then fix the workpiece 10 on the carrier plate 110 through the first limiting component 120 and the second limiting component 130. Since at least partial components of the forces applied by the first limiting component 120, the second limiting component 130, and the first groove 111 to the workpiece 10 are coplanar, and the angle between any two of them is less than 180 degrees, the workpiece 10 is in force balance and is reliably fixed on the carrier plate 110. At the same time, the cavity of the workpiece 10 is exposed outside, which does not affect the subsequent assembly of components in its cavity.

[0103] In this embodiment, the structures of the first limiting component 120 and the second limiting component 130 are different, as will be described in detail below. In other embodiments, the first limiting component 120 and the second limiting component 130 may also have the same structure, and the third part 13 and the second part 12 of the workpiece 10 may also be located in different regions on the same side of the workpiece 10.

[0104] The structure of the second limiting component 130 will be described in detail below.

[0105] To enable the second limiting component 130 to switch between the limiting state and the non-limiting state, the specific structure of the second limiting component 130 is as follows:

[0106] Please refer toFigure 2 and Figure 6 , Figure 6 is Figure 2 the A-A sectional view in

[0107] As Figure 2 and Figure 6 shown, the second limiting component 130 includes a push block 131, a first elastic member 132, and a first ejector rod 133. The push block 131 is located on one side of the first groove 111 and is movably arranged on the carrier plate 110 in a first direction; the first elastic member 132 is arranged between the push block 131 and the carrier plate 110; the first ejector rod 133 is movably arranged on the carrier plate 110 in a second direction, and the first ejector rod 133 abuts against the push block 131 to form a transmission cooperation structure; wherein, the first elastic member 132 is used to generate an elastic force to drive the push block 131 to move towards the first groove 111, and then abut against the workpiece 10, and the first ejector rod 133 drives the push block 131 to move away from the first groove 111 during the movement of the first ejector rod 133, so that the push block 131 is separated from the workpiece 10.

[0108] In this embodiment, the shape of the end of the push block 131 facing the first groove 111 can be matched with the workpiece 10 to more stably abut against the workpiece 10. The push block 131 can be connected to the carrier plate 110 through a linear guide slider structure 138, and the linear guide slider structure 138 is used to guide the push block 131 to move relative to the carrier plate 110 in the first direction. The first elastic member 132 can be a spring.

[0109] When the first ejector rod 133 does not act, the elastic force generated by the first elastic member 132 drives the push block 131 to abut against the workpiece 10, so that the second limiting component 130 is in a limiting state; when the first ejector rod 133 acts, it drives the push block 131 to move away from the first groove 111, so that the second limiting component 130 is in a non-limiting state. By controlling the action of the first ejector rod 133, the second limiting component 130 can be selectively limited.

[0110] In other embodiments, the following scheme can also be adopted: the first elastic member 132 is used to generate an elastic force to drive the push block 131 to move away from the first groove 111, and then away from the workpiece 10, and the first ejector rod 133 drives the push block 131 to move towards the first groove 111 during the movement of the first ejector rod 133, so that the push block 131 abuts against the workpiece 10. This scheme also realizes the selective limiting of the second limiting component 130 by controlling the action of the first ejector rod 133.

[0111] Furthermore, the manner in which the first elastic member 132 is arranged between the push block 131 and the carrier plate 110 is as follows:

[0112] The bearing plate 110 is convexly provided with a fixing block 134. The fixing block 134 and the pushing block 131 are arranged at intervals in the first direction. The first elastic member 132 abuts between the pushing block 131 and the fixing block 134. The fixing block 134 can be a separate part or a part of the bearing plate 110. In addition to facilitating the arrangement of the first elastic member 132, the fixing block 134 can also limit the position of the pushing block 131.

[0113] Further, the first direction is parallel to the bearing plate 110, and the second direction is perpendicular to the bearing plate 110.

[0114] During the reciprocating movement of the pushing block 131 in the direction parallel to the bearing plate 110, the height in the direction perpendicular to the bearing plate 110 does not change, which is convenient for arranging other components on the side of the first groove 111 of the bearing plate 110 and makes the structure of the fixture 100 more compact. The first ejector rod 133 reciprocates in the direction perpendicular to the bearing plate 110, which is convenient for the abutting rod 223 to drive the first ejector rod 133 to move when the first clamping assembly 220 and the second clamping assembly 240 clamp the fixture 100 (see the part of the abutting rod 223 below for details).

[0115] Further, the transmission cooperation structure formed by the first ejector rod 133 and the pushing block 131 is as follows:

[0116] The pushing block 131 is provided with a second groove 1311; the first ejector rod 133 penetrates the bearing plate 110 at a position corresponding to the second groove 1311 and is slidably engaged with the bearing plate 110 in the second direction. The first ejector rod 133 is provided with an inclined surface 1331 at the end close to the pushing block 131, and the inclined surface 1331 abuts against the edge of the second groove 1311.

[0117] In this embodiment, the second groove 1311 penetrates the pushing block 131 in the second direction. The bearing plate 110 is provided with a hole penetrating in the second direction, and the first ejector rod 133 is arranged in the hole and is slidably engaged with the bearing plate 110.

[0118] When the first ejector rod 133 moves towards the pushing block 131, the pushing block 131 is pushed by the inclined surface 1331, thereby driving the pushing block 131 to move.

[0119] Further, the second limiting component 130 further includes a first limiting portion 135, a second limiting portion 136 and a second elastic member 137. The first limiting portion 135 protrudes from the first ejector rod 133 in a direction perpendicular to the second direction and is located at one end of the first ejector rod 133 close to the pushing block 131; the second limiting portion 136 protrudes from the first ejector rod 133 in a direction perpendicular to the second direction and is located at the other end of the first ejector rod 133; the second elastic member 137 abuts between the second limiting portion 136 and the bearing plate 110.

[0120] Among them, the first limiting portion 135 is used to abut against the carrier plate 110 to limit the first ejector rod 133. The second limiting portion 136 facilitates the installation of the second elastic member 137 on the one hand. On the other hand, when a plurality of first ejector rods 133 are provided in the second limiting assembly 130, the second limiting portion 136 is fixedly connected to the plurality of first ejector rods 133, so that the plurality of first ejector rods 133 act in unison. The second elastic member 137 can be a spring.

[0121] By providing the second elastic member 137, the first ejector rod 133 is always kept in a tendency to move away from the push block 131, thereby preventing the inclined surface 1331 from obstructing the contact between the push block 131 and the workpiece 10. It can also enable the first ejector rod 133 to reset in time after moving towards the push block 131.

[0122] The structure of the first limiting assembly 120 will be described in detail below.

[0123] Please refer to Figure 7 and Figure 8 , Figure 7 which is a schematic structural view of the first limiting assembly in the fixture embodiment of the present application, Figure 8 is Figure 7 the right view of

[0124] As Figure 7 and Figure 8 shown, the first limiting assembly 120 includes a support 121 and a movable member 122. The support 121 is fixedly provided on the side surface of the first groove 111 of the carrier plate 110. One end of the movable member 122 is hinged to the support 121, and the other end is provided with a notch 1221 for clamping the second part 12 of the workpiece 10 exposed from the first groove 111 when the movable member 122 rotates to the first predetermined position.

[0125] The support 121 can be a separate component or a part of the carrier plate 110.

[0126] The movable member 122 restricts the movement of the workpiece 10 in the direction perpendicular to the carrier plate 110, thereby restricting the workpiece 10 in the first groove 111. When the second limiting assembly 130 abuts against the workpiece 10, the inner wall surface of the notch 1221 abuts against the workpiece 10, so as to cooperate with the second limiting assembly 130 and the first groove 111 to clamp the workpiece 10.

[0127] In this embodiment, the workpiece 10 is in the shape of a hemispherical shell. A plurality of first limiting assemblies 120 are provided. Each first limiting assembly 120 is clamped to the second part 12 of the workpiece 10 through the notch 1221 for limiting. However, the workpiece 10 may still rotate in the first groove 111. By providing the second limiting assembly 130 to abut against the third part 13 of the workpiece 10, the workpiece 10 can be prevented from rotating in the first groove 111.

[0128] Furthermore, the first limiting component 120 further includes a permanent magnet 123, which is disposed on one of the support 121 and the movable member 122; when the movable member 122 rotates to the first predetermined position (the notch 1221 is clamped to the second part 12 of the workpiece 10), the other of the support 121 and the movable member 122 is magnetically attracted to the permanent magnet 123, thereby fixing the movable member 122.

[0129] The position of the movable member 122 is fixed by magnetic attraction. When disassembling the workpiece 10, the movable member 122 can be manually toggled to release the restriction on the workpiece 10.

[0130] In this embodiment, the permanent magnet 123 is disposed on the support 121, and the movable member 122 can be made of a material that can be magnetically attracted by the permanent magnet 123, such as iron. In other embodiments, the permanent magnet 123 can also be disposed on the movable member 122.

[0131] In this embodiment, a plurality of first limiting components 120 are provided and are spaced apart around the first groove 111. The plurality of first limiting components 120 can ensure that the workpiece 10 is more evenly stressed when clamping the workpiece 10.

[0132] To improve production efficiency, the carrier plate 110 is provided with a plurality of first grooves 111, and each first groove 111 is correspondingly provided with a first limiting component 120 and a second limiting component 130. The fixture 100 can transport a plurality of workpieces 10 to the set working station at one time, improving production efficiency.

[0133] This application also provides an assembly device, which includes the above-mentioned fixture 100 and a flipping device for driving the fixture 100 to rotate by a certain angle. The workpiece 10 rotates by a certain angle under the drive of the flipping device, so as to facilitate loading different components into the cavity of the workpiece 10.

[0134] The fixture 100 and the flipping device are separately provided, and one flipping device can correspond to a plurality of fixtures 100. This is conducive to realizing automated continuous operation and improving processing efficiency.

[0135] Please refer to Figures 9 to 11 , Figure 9 which is a schematic structural diagram of an embodiment of the flipping device of this application, Figure 10 is Figure 9 the left view of Figure 11 is Figure 9 the top view of

[0136] As shown in Figures 9 to 11As shown, the flipping device 200 includes a base 210, a first clamping assembly 220, a first driver 230, a second clamping assembly 240, and a second driver 250. The first clamping assembly 220 is rotatably arranged on the base 210; the first driver 230 is used to drive the first clamping assembly 220 to rotate relative to the base 210; the second clamping assembly 240 is arranged at an interval from the first clamping assembly 220 and is movably connected to the first clamping assembly 220 in the interval direction; the second driver 250 is used to drive the second clamping assembly 240 to approach or move away from the first clamping assembly 220; wherein, the first clamping assembly 220 and the second clamping assembly 240 are used to clamp the fixture 100 and drive it to rotate relative to the base 210.

[0137] The base 210 can be fixedly arranged, the first clamping assembly 220 can be hinged to the base 210, the first driver 230 can be a cylinder, the second clamping assembly 240 and the first clamping assembly 220 can be connected through a guide post and guide sleeve structure, and the second driver 250 can be a cylinder.

[0138] Operation process:

[0139] The second driver 250 drives the second clamping assembly 240 to move away from the first clamping assembly 220;

[0140] Place the fixture 100 carrying the workpiece 10 between the second clamping assembly 240 and the first clamping assembly 220;

[0141] The second driver 250 drives the second clamping assembly 240 to approach the first clamping assembly 220 until the fixture 100 is clamped;

[0142] The first driver 230 drives the first clamping assembly 220 to rotate relative to the base 210 to a second predetermined position;

[0143] The third limiting assembly 260 fixes the first clamping assembly 220.

[0144] Furthermore, the second clamping assembly 240 is provided with a through opening 2411. When the first clamping assembly 220 and the second clamping assembly 240 clamp the fixture 100, the opening 2411 corresponds to the first groove 111. Components can be loaded into the cavity of the workpiece 10 through the opening 2411.

[0145] Specifically, the second clamping assembly 240 includes a first mounting plate 241 and a pressing plate 242. The first mounting plate 241 is disposed at an interval from the first clamping assembly 220 and is movably connected to the first clamping assembly 220 in the interval direction. The opening 2411 penetrates through the first mounting plate 241; the pressing plate 242 is disposed on the side surface of the first mounting plate 241 facing the first clamping assembly 220; when the first clamping assembly 220 and the second clamping assembly 240 clamp the fixture 100, the pressing plate 242 is used to press on the fourth part of the workpiece 10 exposed from the first groove 111. The fourth part of the workpiece 10 is the area in the second part 12 not covered by the first limiting assembly 120. In this embodiment, three first limiting assemblies 120 are correspondingly provided for each workpiece 10, and the fourth part is the interval area between the three first limiting assemblies 120 in the second part 12.

[0146] By pressing the workpiece 10 with the pressing plate 242, the first clamping assembly 220 and the second clamping assembly 240 clamp the fixture 100, enabling the fixture 100 and the workpiece 10 to rotate synchronously. At the same time, the fastening degree of the workpiece 10 is improved, preventing the workpiece 10 from shaking when loading components.

[0147] To ensure that the pressing plate 242 can reliably press the workpiece 10, the limiting effect of the second limiting assembly 130 is released by the abutting rod 223 before the pressing plate 242 presses the workpiece 10.

[0148] Specifically, the first clamping assembly 220 includes a second mounting plate 221, a supporting unit 222, and an abutting rod 223. The second mounting plate 221 is rotatably disposed on the base 210, and the first driver 230 is used to drive the second mounting plate 221 to rotate relative to the base 210. The second clamping assembly 240 is disposed at an interval from the second mounting plate 221 and is movably connected to the second mounting plate 221 in the interval direction. The second driver 250 is used to drive the second clamping assembly 240 to approach or move away from the second mounting plate 221; at least a part of the supporting unit 222 is disposed on the side surface of the second mounting plate 221 facing the second clamping assembly 240 and is elastic in the interval direction between the second mounting plate 221 and the second clamping assembly 240; the abutting rod 223 is fixedly disposed on the side surface of the second mounting plate 221 facing the second clamping assembly 240; during the process of the first clamping assembly 220 and the second clamping assembly 240 clamping the fixture 100, the supporting unit 222 elastically supports between the second mounting plate 221 and the fixture 100, and the abutting rod 223 corresponds to the second limiting assembly 130 and is used to force a part of the second limiting assembly 130 to separate from the workpiece 10.

[0149] Specifically, the abutting rod 223 corresponds to the second limiting part 136 in the second limiting assembly 130.

[0150] Specifically, the pressing plate 242 in the second clamping assembly 240 is movably connected to the first mounting plate 241 in the direction of the gap between the second mounting plate 221 and the first mounting plate 241. Furthermore, an elastic member is connected between the pressing plate 242 and the first mounting plate 241 to ensure that the pressing plate 242 always maintains a tendency to move away from the first mounting plate 241. When subjected to an external force, the pressing plate 242 overcomes the elastic force of the elastic member and moves toward the first mounting plate 241 a set distance before coming into contact with the first mounting plate 241.

[0151] The process of the pressing plate 242 pressing the workpiece 10:

[0152] The fixture 100 loaded with the workpiece 10 is placed in the space between the first clamping assembly 220 and the second clamping assembly 240 and placed on the support unit 222. Under the gravity of the fixture 100 and the workpiece 10, the support unit 222 is compressed, but at this time the top of the support unit 222 is higher than the top of the abutting rod 223.

[0153] The second driver 250 drives the first mounting plate 241 to move toward the second mounting plate 221. The pressing plate 242 contacts the workpiece 10, and the clamp 100 overcomes the elastic force of the supporting unit 222 and moves toward the second mounting plate 221. The second limiting portion 136 on the clamp 100 contacts the abutting rod 223, thereby driving the push block 131 to separate from the workpiece 10.

[0154] After the push block 131 is separated from the workpiece 10 , the fixture 100 stops moving relative to the second mounting plate 221 (may be stopped by the limit block 224 described below);

[0155] Driven by the second driver 250 , the first mounting plate 241 continues to move toward the second mounting plate 221 until the first mounting plate 241 contacts the pressing plate 242 . At this time, the pressing plate 242 is pressed tightly against the workpiece 10 .

[0156] Since the push block 131 does not exert pressure on the workpiece 10 when the pressing plate 242 is pressed against the workpiece 10 , the workpiece 10 can be reliably pressed against the supporting plate 110 .

[0157] See also Figure 12 , Figure 12 yes Figure 9 Enlarged view of the middle support unit.

[0158] like Figure 12As shown, the support unit 222 includes a second ejector rod 2221, a third limiting portion 2222, a fourth limiting portion 2223, a third elastic member 2224, and a roller 2225. The second ejector rod 2221 penetrates through the second mounting plate 221 in the direction of the interval between the second mounting plate 221 and the first mounting plate 241 and is slidably engaged therewith; the third limiting portion 2222 is fixedly provided at one end of the second ejector rod 2221 and is located between the second mounting plate 221 and the first mounting plate 241; the fourth limiting portion 2223 is fixedly provided at the other end of the second ejector rod 2221; the third elastic member 2224 abuts between the third limiting portion 2222 and the second mounting plate 221; the roller 2225 is rotatably provided on the third limiting portion 2222 about its axis; during the process that the fixture 100 is inserted into the space clamped by the first clamping assembly 220 and the second clamping assembly 240 in a direction ( Figure 11 the fixture insertion direction in

[0159] ), the roller 2225 abuts against the fixture 100 and rolls relative thereto.

[0160] Due to the provision of the roller 2225, the fixture 100 can be inserted into the space clamped by the first clamping assembly 220 and the second clamping assembly 240 more smoothly. When the first clamping assembly 220 and the second clamping assembly 240 are clamped, the third elastic member 2224 contracts, so that the fixture 100 moves towards the second mounting plate 221, and further the abutting rod 223 abuts against the second limiting portion 136. Figure 9 and Figure 11 As shown, in this embodiment, two support units 222 are provided, and the two support units 222 are arranged at intervals perpendicular to the fixture insertion direction. A plurality of rollers 2225 are provided in each support unit 222, and the plurality of rollers 2225 are arranged at intervals in the fixture insertion direction. During the process that the fixture 100 is inserted into the space clamped by the first clamping assembly 220 and the second clamping assembly 240, the two support units 222 can stably support the fixture 100. At the same time, the plurality of rollers 2225 on the support unit 222 reduce the friction force of the fixture 100 moving in the flipping device 200.

[0161] Furthermore, the first clamping assembly 220 further includes a limiting block 224. The limiting block 224 is fixedly provided on the side surface of the second mounting plate 221 facing the first mounting plate 241. When the first clamping assembly 220 and the second clamping assembly 240 clamp the fixture 100, the limiting block 224 is used to limit the minimum distance between the fixture 100 and the second mounting plate 221.

[0162] Please refer to Figure 10 and Figure 13 , Figure 13 which Figure 10 is the F-direction view in

[0163] As Figure 10 andFigure 13 As shown, the flipping device 200 further includes a third limiting component 260, and the third limiting component 260 is used to position the first clamping component 220 after the first clamping component 220 rotates relative to the base 210 to a second predetermined position.

[0164] Specifically, the third limiting component 260 includes a limiting rod 261, a limiting plate 262, a third driver 263 and a plug pin 264. The limiting rod 261 is arranged on the base 210; the limiting plate 262 is fixed on the first clamping component 220, and a limiting hole 2621 is formed on the limiting plate 262; the third driver 263 is fixed on the base 210; the plug pin 264 is fixed on the driving end of the third driver 263; when the first clamping component 220 rotates relative to the base 210 to the second predetermined position, the limiting rod 261 abuts against the first clamping component 220 to limit the continuous rotation of the first clamping component 220, and the plug pin 264 is inserted into the limiting hole 2621 under the drive of the third driver 263 to position the first clamping component 220.

[0165] By limiting with the plug pin 264 and the limiting hole 2621, the rotation accuracy of the flipping device 200 can be improved.

[0166] Furthermore, a plurality of limiting holes 2621 are formed on the limiting plate 262 to position the first clamping component 220 at multiple angles.

[0167] In summary, those skilled in the art can easily understand that the present application has at least the following advantages:

[0168] At least partial components of the forces applied by the first limiting component, the second limiting component and the first groove to the workpiece are coplanar, and the included angle between any two of them is less than 180 degrees, so that the workpiece can be firmly fixed on the bearing plate.
