Technical Field
[0001] This application relates to the technical field of vertical continuous electroplating, and particularly relates to a fixture device and electroplating equipment. Background Art
[0002] In the field of vertical continuous electroplating, the movement of the fixture usually adopts a guide rail and a conductive fixture head with a guide groove as a relatively common design. However, due to the long length of the electroplating line body and the large weight of a single fixture, during the continuous movement of the conductive fixture with a guide groove on the guide rail, the friction between the fixture and the guide rail is likely to be too large, resulting in wear.

However, this method requires a large amount of conductive paste, increasing the cost, and the conductive paste is prone to drying, and it is easy to produce dregs and powder after friction, polluting the electroplating solution and affecting the normal operation of the electroplating equipment.

This embodiment discloses a fixture device, which includes a guide rail 1, a fixture head 2, a first roller assembly 3 and a fixture. The fixture head 2 is slidably connected to the guide rail 1, and the fixture head 2 can move along the length extension direction of the guide rail 1. The first roller assembly 3 includes a first roller 31. The first roller 31 is connected to the fixture head 2, and the first roller 31 contacts the upper surface of the guide rail 1. The rolling direction of the first roller 31 is the same as the length extension direction of the guide rail 1. The fixture is connected to the fixture head 2, and the fixture is used to fix the workpiece to be electroplated (the workpiece to be electroplated can be a PCB board). Among them, the length extension direction of the guide rail 1 is Figure 2 the X direction in Figure 2 that is, the length extension direction of the fixture head 2, and the width extension direction of the fixture head 2 is Figure 2 the Y direction in

[0046] The first roller 31 of this embodiment is connected to the fixture head 2, and the first roller 31 contacts the upper surface of the guide rail 1. The rolling direction of the first roller 31 is the same as the length extension direction of the guide rail 1. When the fixture head 2 moves, the friction and wear between the fixture head 2 and the guide rail 1 due to gravity are reduced through the first roller 31, thereby reducing the amount of conductive paste used, lowering the cost, and ensuring the normal operation of the electroplating equipment.
[0047] Referring to Figure 1As shown, the fixture head 2 includes a fixture plate 22, a first slider 23 and a second slider 24. The first slider 23 and the second slider 24 are respectively connected to the fixture plate 22 and are arranged at intervals along the height extension direction of the fixture plate 22. One end of the first slider 23 facing the second slider 24 has a first limiting groove 230. One end of the second slider 24 facing the first slider 23 has a second limiting groove 240. The upper part of the guide rail 1 is slidably arranged in the first limiting groove 230, and the lower part of the guide rail 1 is slidably arranged in the second limiting groove 240.

The fixture is connected to the fixture plate 22.
[0048] Referring to Figure 1 and Figure 2 As shown, the top wall of the first limiting groove 230 is provided with a first contact surface 230a and a second contact surface 230b. The first contact surface 230a and the second contact surface 230b are respectively in contact with the upper surface of the guide rail 1, and the first contact surface 230a and the second contact surface 230b are respectively located on both sides of the first roller 31.

The first accommodating groove 231 is communicated with the first limiting groove 230 through the opening 231a. The first roller 31 is arranged in the first accommodating groove 231. By replacing part of the surface-to-surface sliding friction between the first limiting groove 230 and the upper surface of the guide rail 1 with the line-to-surface rolling friction of the first roller 31, the friction and wear between the fixture head 2 and the guide rail 1 caused by gravity are reduced. The first contact surface 230a and the second contact surface 230b are respectively located on both sides of the opening 231a.
[0049] In this embodiment, through the surface-to-surface contact between the first contact surface 230a and the second contact surface 230b and the upper surface of the guide rail 1, and the line-to-surface contact between the first roller 31 and the upper surface of the guide rail 1, when the fixture head 2 moves, while reducing the friction and wear between the fixture head 2 and the guide rail 1, it also ensures that there is a certain amount of friction between the fixture head 2 and the guide rail 1, thereby reducing the unstable movement of the fixture head 2 when there is only line-to-surface contact, and improving the stability and reliability of the movement of the fixture head 2.

The first roller assembly 3 further includes a first connecting shaft 32 and a first nut 33. The first connecting shaft 32 is connected to the fixture plate 22 and is located within the first receiving groove 231, and the first connecting shaft 32 extends along the width extension direction of the fixture plate 22. The first roller 31 is sleeved on the first connecting shaft 32 and is rotatably connected to the first connecting shaft 32. The first nut 33 is sleeved on the first connecting shaft 32. The first nut 33 is used to ensure the stability of the connection between the first connecting shaft 32 and the fixture plate 22 when the first connecting shaft 32 is connected to the fixture plate 22, thereby ensuring the stability of the first roller 31 during rolling and facilitating the installation of the first roller assembly 3.
[0051] In this embodiment, the first roller assembly 3 has a double ball bearing structure. The double ball bearing structure has a high load-bearing capacity and relatively high radial and axial rigidity, ensuring the stability and accuracy of the movement of the fixture head 2. It can be understood that in other embodiments, the first roller assembly 3 can also have other structures, such as a single ball bearing structure.
[0052] In this embodiment, the first roller assembly 3 further includes a first snap ring 34. The first snap ring 34 is sleeved on the first connecting shaft 32 and is located at one end of the first roller 31 away from the first nut 33. The first snap ring 34 is used to limit the first roller 31 axially to ensure the stability of the movement of the first roller 31.
[0053] In this embodiment, there is one set of the first roller assembly 3. It can be understood that in other embodiments, there can also be two sets or more than two sets of the first roller assembly 3.
[0054] Refer to Figure 1 、 Figure 2 and Figure 4 as shown, Figure 4Perspective view of the second roller assembly of the fixture device provided by the embodiment of the present application. A second receiving groove 241 is provided on the side of the second slider 24. The second receiving groove 241 communicates with the second limiting groove 240. The fixture device further includes a second roller assembly 4. The second roller assembly 4 includes a second roller 41, a second connecting shaft 42, and a second nut 43.

The second roller 41 is located in the second receiving groove 241, and the second roller 41 contacts the side surface of the guide rail 1. The rolling direction of the second roller 41 is the same as the length extension direction of the guide rail 1. By replacing part of the surface-to-surface sliding friction between the side of the second limiting groove 240 and the side surface of the guide rail 1 with the line-to-surface rolling friction of the second roller 41, the frictional wear generated between the side of the fixture head 2 and the side of the guide rail 1 is reduced. The second nut 43 is sleeved on the second connecting shaft 42. The second nut 43 is used to ensure the stability of the connection between the second connecting shaft 42 and the second slider 24 when the second connecting shaft 42 is connected to the second slider 24, thereby ensuring the stability of the second roller 41 during rolling.

[0058] The second roller 41 of this embodiment contacts the side surface of the guide rail 1. The rolling direction of the second roller 41 is the same as the length extension direction of the guide rail 1. When the fixture head 2 moves, the frictional wear generated by the pulling force between the fixture head 2 and the side of the guide rail 1 is reduced by the second roller 41, thereby further reducing the amount of conductive paste used, reducing the cost, and ensuring the normal operation of the electroplating equipment.
