Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone middle frame production, and particularly relates to a steel sheet positioning device for a mobile phone middle frame. Background Art

[0002] A mobile phone, also known as a "handheld mobile telephone", a "handheld wireless telephone", or a "mobile phone handset", is usually commonly referred to as a "mobile phone". Common mobile phones include smart phones and feature phones. A smart phone, like a personal computer, has an independent and open operating system and mostly has a large-size capacitive touch screen for easy operation. A smart phone includes many components such as a main board, a camera, a battery, and a screen, and these components need to be fixed to the middle frame. The mobile phone middle frame is the main frame of the mobile phone. During the production and processing process, steel sheets need to be welded at preset positions on the mobile phone middle frame. The steel sheets are pre-processed into specifications corresponding to the mobile phone middle frame and made into a strip. When welding the steel sheets, the traditional method is for workers to take the steel sheets from the strip, transfer them to the mobile phone middle frame, and then place the steel sheets in the corresponding welding area, and use welding equipment to weld the steel sheets to the mobile phone middle frame. However, the size of the steel sheets is small, and manual feeding is not only time-consuming and laborious, but also prone to position deviation, resulting in welding errors. Although there are some auxiliary devices on the market that can perform steel sheet feeding, which can take the steel sheets from the strip and transfer them to the mobile phone middle frame, it is still difficult to ensure the accuracy of the steel sheet placement position.

Specific embodiments

[0023] To facilitate the understanding of the present utility model by those skilled in the art, the present utility model will be further described in detail below in conjunction with specific embodiments and the accompanying drawings.

[0024] Referring to Figures 1 to 4 , this embodiment provides a steel sheet positioning device for a mobile phone middle frame, including a base 1, an adjusting mechanism 2 connected to the base 1, a steel sheet positioning mechanism 3 disposed on the adjusting mechanism 2, and a position adjusting mechanism 4 disposed on the base 1, and the position adjusting mechanism 4 is connected to the adjusting mechanism 2. In this embodiment, the base 1 is provided with a guide rail in the X-axis direction, and the adjusting mechanism 2 is connected to the guide rail.

[0025] The steel sheet positioning mechanism 3 includes a base plate 31 connected to the adjusting mechanism 2, a substrate 32 connected to the base plate 31, a fixing plate 33 disposed on one side of the substrate 32, a fixed positioning member 34 disposed on the fixing plate 33, a movable positioning member corresponding to the fixed positioning member 34, and a positioning driving assembly 35 for driving the movable positioning member to move. The positioning driving assembly 35 can drive the movable positioning member to approach or move away from the fixed positioning member 34. During the steel sheet positioning process, after the steel sheet is transferred to the fixed positioning member 34, the positioning driving assembly 35 drives the movable positioning member to approach the fixed positioning member 34, and cooperates with the fixed positioning member 34 to limit the steel sheet at a predetermined position, that is, the positioning is completed.

[0026] The positioning and driving assembly 35 includes a positioning driver 351 disposed on the substrate 32, a movable plate 352 connected to the output end of the positioning driver 351, and the movable positioning member is disposed on the movable plate 352. In this embodiment, the positioning driver 351 is a cylinder, the output end of the cylinder is connected to the movable plate 352, and the driving direction of the positioning driver 351 forms a certain angle with the X-axis, so that the movable positioning member approaches the fixed positioning member 34 from the oblique side.

[0027] The adjusting mechanism 2 includes an adjusting seat 21 movably connected to the base 1, a Y-axis adjusting platform 22 disposed on the adjusting seat 21, an X-axis adjusting platform 23 connected to the Y-axis adjusting platform 22, and the bottom plate 31 is connected to the X-axis adjusting platform 23. The X-axis adjusting platform 23 and the Y-axis adjusting platform 22 can adjust the position of the steel sheet positioning mechanism 3, so as to facilitate adjustment according to the on-site environment to match other equipment, such as matching the position with the steel sheet feeding device.

[0028] The position adjusting mechanism 4 includes a plurality of fixed seats 41 disposed on the base 1, a sliding rod 42 connected to the fixed seats 41, and a connecting component 43 for connecting the sliding rod 42 and the adjusting mechanism 2. The sliding rod 42 is disposed along the X-axis direction. In this embodiment, there are three fixed seats 41, corresponding to both ends and the middle of the sliding rod 42 respectively.

[0029] The connecting component 43 includes a connecting member 431 for connecting the sliding rod 42 and the adjusting mechanism 2, and a locking member 432 for locking the connecting member 431 and the sliding rod 42. The connecting member 431 can move along the sliding rod 42, thereby driving the adjusting mechanism 2 to move. When it moves to a suitable position, the locking member 432 is used to lock the connecting member 431 and the sliding rod 42. Under the action of the connecting component 43, the adjusting mechanism 2 and the steel sheet positioning mechanism 3 can be conveniently adjusted according to the on-site environment to match other equipment, such as matching the position with the steel sheet feeding device. In this embodiment, the structure of the connecting member 431 is similar to a hoop. After the locking member 432 is tightened, the connecting member 431 tightly holds the sliding rod 42 to achieve fixation.

[0030] The fixed positioning member 34 is provided with a positioning hole 36 matching the steel sheet, and an opening 37 is provided on one side of the positioning hole 36. During actual work, the present utility model cooperates with a steel sheet feeding device for operation. The opening 37 can allow the picking member of the steel sheet feeding device to enter the positioning hole 36.

[0031] The top surface of the fixed positioning member 34 is provided with a positioning portion 38 for positioning the steel sheet, and the movable positioning member is provided with a positioning concave portion 39 that matches the positioning portion 38. The positioning portion 38 and the positioning concave portion 39 are designed according to the outer dimensions of the steel sheet and can enclose the steel sheet. Since the position of the steel sheet on the strip cannot be guaranteed to be precise, and the strip unwinding process is prone to deviation due to sliding or other reasons, it is necessary to transfer the steel sheet to the fixed positioning member 34. Through the cooperation of the fixed positioning member 34 and the movable positioning member, the steel sheet is pushed and limited to a predetermined position. Each steel sheet can be ensured to be in the same position, thus ensuring the accuracy of the steel sheet feeding device during feeding.

[0032] The steel sheet positioning device for the mobile phone middle frame includes a steel sheet transfer mechanism 5. The steel sheet transfer mechanism 5 includes a multi-axis moving module 51 and a material suction member 52 connected to the multi-axis moving module 51. In this embodiment, the multi-axis moving module 51 is a three-axis moving module, specifically composed of two linear moving modules forming the X-axis and Y-axis, and a cylinder forming the Z-axis. The material suction member 52 is connected to the cylinder. The steel sheet transfer mechanism 5 can transfer the steel sheet from the strip to the steel sheet positioning mechanism 3.

[0033] Three fixed positioning members 34 are provided on the fixed plate 33, and the number of movable positioning members is the same as that of the fixed positioning members 34. Four adjusting mechanisms 2 and steel sheet positioning mechanisms 3 are provided. That is to say, this embodiment can position multiple steel sheets simultaneously, adapting to large-scale welding processing operations. Of course, in actual implementation, the number of the fixed positioning members 34, movable positioning members, adjusting mechanisms 2, and steel sheet positioning mechanisms 3 is not specifically limited, and they can be arranged according to actual production requirements.

[0034] During specific operation, the material picking member moves upward from below the fixed positioning member 34 into the positioning hole 36. At this time, the steel sheet is placed on the material picking member. Then, the movable positioning member approaches the fixed positioning member 34, and the positioning concave portion 39 pushes the steel sheet to move until the steel sheet is limited within the positioning concave portion 39 and the positioning portion 38. At this time, the steel sheet is positioned. The material picking member uses negative pressure to adsorb the steel sheet. After that, the movable positioning member resets, and the material picking member can leave the fixed positioning member 34 to transfer the steel sheet to the mobile phone middle frame.

[0035] The present utility model is provided with a steel sheet positioning mechanism 3. When the steel sheet is transferred to the fixed positioning member 34, with the cooperation of the movable positioning member, the steel sheet is limited to a predetermined position, so as to ensure that each steel sheet is in the same position during feeding. Furthermore, the steel sheet can be accurately placed at the preset position of the mobile phone middle frame, ensuring the welding quality and improving the qualified rate. On the other hand, the present utility model is provided with an adjusting mechanism 2 and a position adjusting mechanism 4, which can flexibly adjust the position of the steel sheet positioning mechanism 3 to adapt to different on-site environments and has strong versatility.
