Description

Technical Field

[0001] This application belongs to the field of fixture technology, and particularly relates to a fixture and a pad printing device. Background Technology

[0002] Pad printing is a type of printing method that can print text, graphics, and images on the surface of irregularly shaped objects. Pad printing machines are usually equipped with a pad printing head made of silicone rubber. By dipping the head in ink with a pre-set pattern and pressing it up and down on the corresponding position on the material to be printed, the pad printing is completed.

[0003] In the pad printing process for mobile phone frames, the ink position on the frame is typically perpendicular to the printing head. During the printing process, when the printing head applies pressure to the frame, the frame, located on the fixture, will shift due to the pressure, thus reducing the printing accuracy.

[0048] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0049] First, it should be noted that the X, Y, and Z directions mentioned in the embodiments of this application are referred to in the appendix. Figure 1 , Figure 4 and Figure 5 The marked directions; wherein the axes in the X direction, Y direction, and Z direction intersect each other.

[0050] The fixture 100 of this application is suitable for clamping mobile phone mid-frame 200, tablet mid-frame, watch mid-frame, computer mid-frame, etc.; this application takes clamping mobile phone mid-frame 200 as an example for explanation.

[0051] The mobile phone frame 200 includes a base plate 202 and a frame 201. The frame 201 is connected to the periphery of the base plate 202 and surrounds the base plate 202.

[0052] like Figures 1-5 As shown, according to a first aspect of the embodiments of this application, a jig 100 is provided, including a mounting base 1, a gripper assembly 2, a drive assembly 3, and a support assembly 4; the gripper assembly 2 is slidably connected to the mounting base 1; the drive assembly 3 is disposed on the mounting base 1, and the movable end of the drive assembly 3 can abut against the gripper assembly 2; the support assembly 4 is disposed on the mounting base 1, and the support assembly 4 is located on the moving path of the gripper assembly 2.

[0053] like Figure 1 and Figure 2 As shown, the fixture 100 includes a mounting base 1, a gripper assembly 2, a drive assembly 3, and a support assembly 4. The gripper assembly 2 is used to position and hold the mobile phone frame 200, and the support assembly 4 is used to support the inner surface of the frame 201. The gripper assembly 2 is slidably connected to the mounting base 1 and can move relative to the mounting base 1 in the Z direction. The drive assembly 3 is located on the mounting base 1, and the moving end of the drive assembly 3 can approach and abut against the gripper assembly 2 to drive the gripper assembly 2 to move relative to the mounting base 1 in the Z direction. The support assembly 4 is located on the mounting base 1 and is situated on the movement path of the gripper assembly 2. That is, when the gripper assembly 2 moves in the Z direction, it can approach or move away from the support assembly 4.

[0054] To further explain, the gripper assembly 2 clamps and supports the mobile phone frame 200, with the inner surface of the frame 201 facing the support assembly 4. The drive assembly 3 drives the gripper assembly 2 to move closer to the support assembly 4, enabling the inner surface of the frame 201 to contact the support assembly 4, thus allowing the support assembly 4 to support the frame 201. When the ink head of the ink printing assembly moves closer to the frame 201 and presses against it, the support assembly 4 provides support, thereby preventing the ink head from moving when pressing against the mobile phone frame 200, thus improving the ink printing accuracy.

[0055] The gripper assembly 2 and the mounting base 1 are slidably connected via the sliding assembly 6.

[0056] In one alternative embodiment, the drive component 3 can drive the gripper component 2 to move toward or away from the support component 4.

[0057] like Figure 1 and Figure 2 As shown, in an optional embodiment, the fixture 100 includes two support components 4, which are spaced apart; specifically, the two support components 4 are respectively labeled as first support component 4a and first support component 4b, and the first support component 4a and first support component 4b are arranged spaced apart along the Z direction.

[0058] Further explanation: the drive assembly 3 includes two first drive members 31, which are disposed between the two support assemblies 4, with their moving ends arranged opposite to each other. Specifically, the drive assembly 3 includes two first drive members 31, referred to as first sub-drive member 31a and second sub-drive member 31b, respectively. Both first sub-drive member 31a and second sub-drive member 31b are disposed on the mounting base 1, and are located between the first support assembly 4a and the first support assembly 4b in the Z direction. The moving ends of the first sub-drive member 31a and the second sub-drive member 31b are arranged opposite to each other. This can be understood as follows: the moving end of the first sub-drive member 31a is used to drive the gripper assembly 2 to move closer to the first support assembly 4a in the Z direction, and the moving end of the second sub-drive member 31b is used to drive the gripper assembly 2 to move closer to the first support assembly 4b in the Z direction.

[0059] Further explanation: The gripper assembly 2 clamps and supports the mobile phone frame 200. The frame 201 includes four inner surfaces, with the first inner surface and the second inner surface arranged opposite each other along the Z direction. The first inner surface faces the first support assembly 4a, and the second inner surface faces the first support assembly 4b. The first sub-drive member 31a drives the gripper assembly 2 to move closer to the first support assembly 4a, enabling the first inner surface of the frame 201 to contact the first support assembly 4a, thus allowing the first support assembly 4a to support the frame 201. When it is necessary to perform transfer printing on the other side of the mobile phone frame 200, the fixture 100 is rotated 180 degrees, and the second sub-drive member 31b drives the gripper assembly 2 to move closer to the first support assembly 4b, enabling the second inner surface of the frame 201 to contact the first support assembly 4b, thus allowing the first support assembly 4b to support the frame 201. In this embodiment, by providing two support assemblies 4 and two first drive members 31, transfer printing can be performed on both sides of the mobile phone frame 200.

[0060] like Figure 2As shown, in an optional embodiment, the drive assembly 3 further includes a support base 32, which is disposed on the mounting base 1, and both first drive members 31 are disposed on the support base 32.

[0061] like Figure 1 As shown, in an optional embodiment, the support component 4 includes a plurality of support portions 41, which are spaced apart. Specifically, any support component 4 includes a plurality of support portions 41, which are spaced apart along the X direction. The support component 4 includes a plurality of support portions 41, which can be understood as including two, three, or more support portions 41. The number of support portions 41 can be determined according to the number of ink positions 203 that need to be transferred on one side of the mobile phone frame 200. For example, if two ink positions 203 need to be transferred on one side of the mobile phone frame 200, the support component 4 includes two support portions 41. When the gripper component 2 clamps the mobile phone frame 200, one support portion 41 corresponds to one ink position 203.

[0062] Each support part 41 can be a separate structure, or multiple support parts 41 can be a single integrated structure.

[0063] like Figure 3 and Figure 4 As shown, in an optional embodiment, the gripper assembly 2 includes a mounting plate 21, a second driving member 22, and a positioning member 23. The mounting plate 21 is slidably connected to the mounting base 1. The second driving member 22 is disposed on the mounting plate 21, and the positioning member 23 is disposed at the moving end of the second driving member 22. Specifically, the mounting plate 21 is slidably connected to the mounting base 1 and can slide relative to the mounting base 1 in the Z direction. The second driving member 22 is disposed on the mounting plate 21, and the positioning member 23 is disposed at the moving end of the second driving member 22. The second driving member 22 can drive the positioning member 23 to extend into the frame 201 so that the positioning member 23 can abut against the inner surface of the frame 201 to position the mobile phone frame 200. Furthermore, the abutment of the positioning member 23 against the inner surface of the frame 201 can prevent damage to the outer surface of the mobile phone frame 200.

[0064] The position of the positioning element 23 does not coincide with the position of the support component 4. This can be understood as the positioning element 23 and the support component 4 abutting at intervals, corresponding to the same inner surface.

[0065] like Figure 3 and Figure 4As shown, in an optional embodiment, the gripper assembly 2 further includes a first abutment portion 26 and a second abutment portion 27, which are spaced apart along the Z direction on the mounting plate 21. The moving end of the first sub-drive member 31a can abut against the first abutment portion 26, and the moving end of the second sub-drive member 31b can abut against the second abutment portion 27. In this embodiment, the first abutment portion 26 and the second abutment portion 27 are provided to abut against the first sub-drive member 31a and the second sub-drive member 31b.

[0066] like Figure 3 and Figure 4 As shown, in an optional embodiment, the positioning member 23 includes a first positioning part 231, a second positioning part 232, a third positioning part 233, and a fourth positioning part 234. The first positioning part 231 and the third positioning part 233 are arranged opposite to each other, and the second positioning part 232 and the fourth positioning part 234 are arranged opposite to each other. Specifically, the first positioning part 231 and the third positioning part 233 are arranged opposite to each other along the Z direction, and the second positioning part 232 and the fourth positioning part 234 are arranged opposite to each other along the X direction. The frame 201 is annular and includes four inner surfaces. The first positioning part 231, the second positioning part 232, the third positioning part 233, and the fourth positioning part 234 are respectively... The second driving member 22 can simultaneously drive the first positioning part 231 to move closer to or further away from the inner surface of the frame 201 along the Z direction, the second positioning part 232 to move closer to or further away from the inner surface of the frame 201 along the X direction, the third positioning part 233 to move closer to or further away from the inner surface of the frame 202 along the Z direction, and the fourth positioning part 234 to move closer to or further away from the inner surface of the frame 202 along the X direction; thereby positioning the mobile phone frame 200 to ensure its positioning accuracy; and the first positioning part 231, the second positioning part 232, the third positioning part 233 and the fourth positioning part 234 each abut against an inner surface, which can also clamp the mobile phone frame 200.

[0067] The moving end of the second driving member 22 includes four connection points. The first positioning part 231, the second positioning part 232, the third positioning part 233 and the fourth positioning part 234 are respectively connected to one connection point. The second driving member 22 can simultaneously drive the first positioning part 231, the second positioning part 232, the third positioning part 233 and the fourth positioning part 234 to move at the same time.

[0068] Specifically, the second driving component 22 includes a motor, a gear, and four racks. The gear is connected to the output end of the motor, and all four racks mesh with the gear. The first positioning part 231, the second positioning part 232, the third positioning part 233, and the fourth positioning part 234 are each connected to one rack. The motor drives the gear to rotate, which in turn drives the four racks to move, thereby simultaneously moving the first positioning part 231, the second positioning part 232, the third positioning part 233, and the fourth positioning part 234.

[0069] Alternatively, the second driving component 22 is a pneumatic gripper cylinder including four moving ends. The first positioning part 231, the second positioning part 232, the third positioning part 233 and the fourth positioning part 234 are respectively connected to one moving end. The pneumatic gripper cylinder can simultaneously drive the first positioning part 231, the second positioning part 232, the third positioning part 233 and the fourth positioning part 234 to move.

[0070] like Figure 4 As shown, in an optional embodiment, the first positioning part 231, the second positioning part 232, the third positioning part 233, or the fourth positioning part 234 includes a positioning block 2341, a push rod 2342, and an elastic member 2343. The positioning block 2341 is disposed at the moving end of the second driving member 22, the push rod 2342 is slidably connected to the positioning block 2341, and the elastic member 2343 is disposed between the push rod 2342 and the positioning block 2341.

[0071] The first positioning part 231, the second positioning part 232, the third positioning part 233, or the fourth positioning part 234 includes a positioning block 2341, a push rod 2342, and an elastic element 2343. It can be understood that any one of the first positioning part 231, the second positioning part 232, the third positioning part 233, or the fourth positioning part 234 includes a positioning block 2341, a push rod 2342, and an elastic element 2343, and the direction of the elastic force of the elastic element 2343 can be the X direction or the Z direction.

[0072] Specifically, the fourth positioning part 234, which includes a positioning block 2341, a push rod 2342, and an elastic element 2343, will be described as an example. The fourth positioning part 234 includes a positioning block 2341, a push rod 2342, and an elastic element 2343. The positioning block 2341 is located at the moving end of the second driving member 22. The push rod 2342 is slidably connected to the positioning block 2341. The sliding direction of the push rod 2342 and the positioning block 2341 is the X direction. The elastic element 2343 is located between the positioning block 2341 and the push rod 2342. The direction of the elastic force of the elastic element 2343 is also the X direction. When the push rod 2342 slides towards the positioning block 2341, the elastic element 2343 will be compressed. In this embodiment, the second driving member 22 drives the fourth positioning part 234 to move along the X direction toward the inner surface of the frame 201, so that the push rod 2342 abuts against the inner surface of the frame 201 and squeezes the elastic member 2343. The elastic force of the elastic member 2343 drives the push rod 2342 away from the positioning block 2341, thereby improving the reliability of clamping the mobile phone frame 200.

[0073] like Figure 1 , Figure 3 and Figure 4 As shown, in an optional embodiment, the gripper assembly 2 further includes an adsorption member 24, which is located at the end of the second drive member 22 away from the mounting plate 21. Specifically, since the fixture 100 needs to be flipped, in order to prevent displacement between the mobile phone frame 200 and the fixture 100 during flipping, the end of the second drive member 22 away from the mounting plate 21 is provided with an adsorption member 24. The adsorption member 24 is provided with a plurality of suction cups 241, which adsorb the bottom surface of the mobile phone frame 200, thereby preventing relative movement between the mobile phone frame 200 and the fixture 100.

[0074] like Figure 1 and Figure 2As shown, in an optional embodiment, the mounting base 1 has a through hole 11, the mounting plate 21 is located on one side of the mounting base 1, the suction member 24 and the positioning member 23 are located on the other side of the mounting base 1, the second driving member 22 is disposed on the mounting plate 21, and the moving end of the second driving member 22 passes through the through hole 11 and is connected to the positioning member 23; specifically, the mounting base 1 has a through hole 11, the axis of the through hole 11 is parallel to the axis in the Y direction, and the through hole 11 penetrates the mounting base 1 in the Y direction; along the Y direction, the mounting plate 21 is located on one side of the mounting base 1. On one side, the adsorption member 24 and the positioning member 23 are located on the other side of the mounting base 1. The second driving member 22 is disposed on the mounting plate 21. The moving end of the second driving member 22 is located on the other side of the mounting base 1. The adsorption member 24 is disposed on the second driving member 22. The positioning member 23 is disposed on the moving end of the second driving member 22. The first driving member 31 is disposed on the side of the mounting base 1 facing the mounting plate 21. When the gripper assembly 2 moves along the Z direction, the gripper assembly 2 can move radially relative to the through hole 11. In this embodiment, by arranging the gripper assembly 2 on both sides of the mounting base 1, the structure of the fixture 100 is made more compact.

[0075] In the above embodiment, the support component 4 is located on the side of the mounting base 1 away from the mounting plate 21.

[0076] like Figure 2 and Figure 4As shown, in an optional embodiment, the gripper assembly 2 includes a connecting portion 25 connected to the mounting plate 21; the fixture 100 further includes a clamping assembly 5 disposed on the mounting base 1, the clamping assembly 5 including a third driving member 51, a first clamping portion 52 and a second clamping portion 53, the first clamping portion 52 and the second clamping portion 53 being spaced apart, the first clamping portion 52 and / or the second clamping portion 53 being connected to the moving end of the second driving member 22, and the connecting portion 25 being located between the first clamping portion 52 and the second clamping portion 53; specifically, the first clamping portion 52 and the second clamping portion 53 are spaced apart along the Z direction, and the third driving member 51 can drive the first clamping portion 52 and the second clamping portion 53 to move towards each other (which can be understood as the first clamping portion 52 being connected to the moving end of the third driving member 51). The second clamping part 53 is fixedly connected to the mounting base 1; or, the second clamping part 53 is connected to the moving end of the third driving member 51, and the first clamping part 52 is fixedly connected to the mounting base 1; or, both the first clamping part 52 and the second clamping part 53 are connected to the moving end of the third driving member 51, and the third driving member 51 can simultaneously drive the first clamping part 52 and the second clamping part 53 to move towards or away from each other, so as to clamp the connecting part 25 between the first clamping part 52 and the second clamping part 53 through the first clamping part 52 and the second clamping part 53, so as to facilitate the gripper assembly 2 when loading the mobile phone frame 200; when pad printing is required, the third driving member 51 can drive the first clamping part 52 and the second clamping part 53 to move away from each other, so as to increase the distance between the first clamping part 52 and the second clamping part 53, that is, to loosen the connecting part 25, so that the gripper assembly 2 can move along the Z direction.

[0077] For example, the specific operation process of fixture 100 in the pad printing process is as follows:

[0078] First, the suction member 24 of the gripper assembly 2 faces upward in the Z direction, and the mobile phone frame 200 is placed on the suction member 24. The second driving member 22 drives the positioning member 23 to move closer to the inner surface of the frame 201. The positioning member 23 abuts against the inner surface of the frame 201, completing the positioning of the mobile phone frame 200. The suction cup 241 of the suction member 24 adsorbs the bottom plate 202 of the mobile phone frame 200.

[0079] Then, when it is necessary to perform pad printing on the mobile phone frame 200, the fixture 100 is rotated 90 degrees so that the ink position 203 to be printed is facing upward in the Z direction and perpendicular to the ink head. The first driving member 31 drives the gripper assembly 2 to move away from the ink head (moving downward) in the Z direction, so that the inner surface of the frame 201 abuts against the support assembly 4. The support assembly 4 plays a supporting role to prevent the mobile phone frame 200 from moving when the ink head presses against the mobile phone frame 200.

[0080] According to a second aspect of the embodiments of this application, a pad printing apparatus is provided, including the fixture 100 described above.

[0081] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
