Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone production, in particular to a double-station mobile phone middle frame clamp. Background Art

[0002] In order to improve the inspection efficiency of the mobile phone middle frame, a robot is usually used to place the mobile phone middle frame on a fixed fixture, the fixture is used to position the product, and then a probe module is used to scan and inspect the periphery of the product.

[0003] The existing devices have some disadvantages during use. For example, the traditional clamp often presses and fixes the middle frame of the mobile phone under the action of its pressure plate to prevent the product from being displaced or shaking during the inspection process. However, after the pressure plate presses the middle frame of the mobile phone, it will block the side of the middle frame of the mobile phone, resulting in the probe module being unable to scan and inspect the side of the middle frame of the mobile phone. Utility Model Content

[0004] The utility model aims to provide a double-station mobile phone middle frame clamp to solve the problem that after the pressing plate presses the mobile phone middle frame, the side of the mobile phone middle frame will be blocked, resulting in the probe module being unable to scan and detect the side of the mobile phone middle frame.

[0005] The utility model provides the following technical solutions: a double-station mobile phone middle frame clamp, comprising a base and a mobile phone middle frame, four mounting frames are fixedly installed on the upper end surface of the base, a plurality of first cylinders are fixed in an array on the upper end surfaces of the four mounting frames, a pressing mechanism is provided on the piston ends of the plurality of first cylinders, a placement frame is provided between two laterally symmetrically arranged mounting frames, two of the placement frames are fixedly installed on the upper end surface of the base, a fixing table for supporting the mobile phone middle frame is fixedly connected to the upper end surface of the placement frame, and a positioning mechanism for fixing the mobile phone middle frame is provided at the side of the placement frame.

[0006] In the above solution, the setting of the mechanism adopts a dual-station design, which means that while processing one mobile phone middle frame at the same time, the other station can perform preparatory work or process other mobile phone middle frames, thereby greatly improving work efficiency.

[0007] Furthermore, the pressing mechanism includes a fixed plate fixed on the piston end of the first cylinder, a pressing arm is rotatably connected to the fixed plate, a fixed seat is fixedly installed on the outer surface of the first cylinder, and linkage plates are rotatably connected to the two opposite side walls of the top of the fixed seat, and the ends of the two linkage plates away from the fixed seat are rotatably connected to the side walls of the pressing arm.

[0008] In the above scheme, the pressing mechanism is driven by the first cylinder (driving source) to press and clamp the middle frame of the mobile phone, so as to prevent the middle frame of the mobile phone from shifting up and down during operation.

[0009] Furthermore, the positioning mechanism includes a positioning plate and a second cylinder, and the positioning plate and the second cylinder are symmetrically fixed on both sides of the upper end surface of the placement rack, respectively. Two positioning plates are provided, and the two positioning plates are laterally symmetrically fixed. The piston end of the second cylinder is fixedly connected to a positioning push plate.

[0010] In the above solution, the mobile phone middle frame is pushed and clamped by the provided positioning mechanism, so as to prevent the mobile phone middle frame from shifting left and right during operation.

[0011] Furthermore, the positioning plate and the positioning push plate are both L-shaped structures.

[0012] In the above solution, the L-shaped structure can disperse and withstand forces from all directions due to its unique shape, thereby ensuring that the fixture can maintain good positioning accuracy and stability during long-term use.

[0013] Furthermore, an auxiliary fixing plate for fixing the two placement racks is detachably fixedly connected between the two placement racks.

[0014] In the above scheme, the auxiliary fixing plate firmly connects the two placement racks together through a detachable fixed connection to form a stable overall structure. This connection method can effectively prevent the placement racks from relative displacement or shaking during use, thereby ensuring the stability and positioning accuracy of the mobile phone middle frame in the fixture.

[0015] Furthermore, the fixing seat is a T-shaped structure.

[0016] In the above scheme, the T-shaped structure itself has good stability and load-bearing capacity

[0017] Furthermore, the upper end surface of the fixing platform is fixedly connected with a plurality of positioning protrusions for positioning the middle frame of the mobile phone.

[0018] In the above solution, the positioning protrusion supports the middle frame of the mobile phone.

[0019] Furthermore, pressing openings adapted to the ends of the pressing arms are provided on the two opposite side walls of the mobile phone middle frame.

[0020] In the above scheme, the setting of the pressing opening allows the end of the pressing arm to accurately extend into the interior of the mobile phone middle frame, thereby achieving precise fixation of the mobile phone middle frame. Since the pressing opening is adapted to the end of the pressing arm, the pressing arm can completely fit the side wall of the mobile phone middle frame, avoiding possible sliding or deviation during the fixing process.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] In the utility model, the positioning operation is performed on the mobile phone middle frame through the provided positioning mechanism to ensure that the mobile phone middle frame will not move or shift in subsequent operations. The first cylinder is the driving source of the pressing mechanism, which is used to drive the pressing mechanism to press and clamp the mobile phone middle frame, so as to avoid the mobile phone middle frame from shifting up and down during operation. The positioning mechanism and the pressing mechanism are set without blocking the mobile phone middle frame. The probe module can accurately scan and detect the sides of the product. This fixture adopts a double-station design, which means that while processing one mobile phone middle frame at the same time, the other station can perform preparation work or process other mobile phone middle frames, thereby greatly improving work efficiency.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] Example 1

[0031] like Figure 1As shown, the utility model provides a technical solution: a double-station mobile phone middle frame fixture, including a base 10 and a mobile phone middle frame 11, four mounting frames 12 are fixedly installed on the upper end surface of the base 10, and multiple first cylinders 13 are fixed in an array on the upper end surfaces of the four mounting frames 12. The piston ends of the multiple first cylinders 13 are all provided with a pressing mechanism. A placement frame 14 is provided between two laterally symmetrically arranged mounting frames 12, and the two placement frames 14 are fixedly installed on the upper end surface of the base 10. An auxiliary fixing member for fixing the two placement frames 14 is detachably fixedly connected between the two placement frames 14. The plate 40 improves the stability of the installation of the placement frame 14. The upper end surface of the placement frame 14 is fixedly connected to a fixing table 15 for supporting the mobile phone middle frame 11. The side of the placement frame 14 is provided with a positioning mechanism for fixing the mobile phone middle frame 11. During specific use, the mobile phone middle frame 11 is first placed on the fixing table 15, and the mobile phone middle frame 11 is positioned by the provided positioning mechanism to ensure that the mobile phone middle frame 11 will not move or deflect in subsequent operations. The first cylinder 13 is a driving source of the pressing mechanism, which is used to drive the pressing mechanism to press and clamp the mobile phone middle frame 11.

[0032] As an implementation method in this embodiment, Figure 1 and Figure 3 As shown, the pressing mechanism includes a fixed plate 20 fixed on the piston end of the first cylinder 13, and a pressing arm 21 is rotatably connected to the fixed plate 20. A fixed seat 22 is fixedly installed on the outer surface of the first cylinder 13. The fixed seat 22 is a T-shaped structure. Linkage plates 23 are rotatably connected to the two opposite side walls of the top of the fixed seat 22. The ends of the two linkage plates 23 away from the fixed seat 22 are rotatably connected to the side walls of the pressing arm 21. During specific use, the fixed seat 22 is a carrier of the linkage plate 23, and the end of the linkage plate 23 is rotatably connected to the pressing arm 21. The fixed plate 20 is driven to move up and down by the extension and contraction of the first cylinder 13. The pressing arm 21 is rotatably connected to the fixed plate 20. Therefore, when the fixed plate 20 moves up and down, the pressing arm 21 can adjust its angle around its rotation point, so that the pressing arm 21 presses and clamps the middle frame 11 of the mobile phone.

[0033] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 4As shown, the positioning mechanism includes a positioning plate 30 and a second cylinder 31, and the positioning plate 30 and the second cylinder 31 are symmetrically fixed on both sides of the upper end surface of the placement rack 14, respectively. Two positioning plates 30 are provided, and the two positioning plates 30 are laterally symmetrically fixed. The piston end of the second cylinder 31 is fixedly connected with a positioning push plate 32. The positioning plate 30 and the positioning push plate 32 are both L-shaped structures. During specific use, the positioning push plate 32 is driven by the second cylinder 31 to move laterally, so that the mobile phone middle frame 11 is fixed between the positioning push plate 32 and the positioning plate 30, so as to complete the clamping and fixing operation, which has the effect of positioning the mobile phone middle frame 11.

[0034] As an implementation method in this embodiment, Figure 1 As shown, the upper end surface of the fixing platform 15 is fixedly connected with a plurality of positioning protrusions 151 for positioning and placing the mobile phone middle frame 11 , and the positioning protrusions 151 lift the mobile phone middle frame 11 .

[0035] As an implementation method in this embodiment, Figure 4 and Figure 5 As shown, pressing openings 111 adapted to the ends of the pressing arms 21 are provided on the two opposite side walls of the mobile phone middle frame 11 , so that the pressing arms 21 can accurately perform pressing and fixing operations.

[0036] Working principle: first, place the mobile phone middle frame 11 on the fixed platform 15, and drive the positioning push plate 32 to move horizontally through the second cylinder 31, so as to fix the mobile phone middle frame 11 between the positioning push plate 32 and the positioning plate 30, so as to complete the clamping and fixing operation, and ensure that the mobile phone middle frame 11 will not move or offset in subsequent operations. The first cylinder 13 is the driving source of the pressing mechanism, and the fixed seat 22 is the carrier of the linkage plate 23. The end of the linkage plate 23 is rotatably connected with a pressing arm 21, and the fixed plate 20 is driven up and down by the extension and contraction of the first cylinder 13. The pressing arm 21 is rotatably connected to the fixed plate 20. Therefore, when the fixed plate 20 moves up and down, the pressing arm 21 can adjust the angle around its rotation point, so that the pressing arm 21 presses and clamps the mobile phone middle frame 11.

[0037] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
