Description

Technical Field

[0001] This utility model relates to the field of mobile phone production equipment technology, and in particular to a pressing fixture for pressing auxiliary materials for mobile phone back covers. Background Technology

[0002] With the widespread use of smartphones, the requirements for mobile phone manufacturing processes are becoming increasingly stringent, especially in the production of mobile phone back covers. As an important component of the mobile phone casing, the back cover not only needs to have a good appearance design, but also needs to ensure sufficient strength and durability. In order to improve production efficiency and quality, the pressing equipment for mobile phone back covers plays a crucial role in the mobile phone manufacturing process.

[0003] Currently, most mobile phone back cover lamination equipment on the market uses mechanical lamination. It employs a pressure device to press the back cover into place, ensuring a tight fit between the back cover and the internal components of the phone. These devices typically consist of a lamination platform, a lamination device, a power system, and a control system. During operation, the back cover is placed on the lamination platform, and then pressure is applied by the lamination device to press it into place. The lamination device is generally hydraulically or pneumatically driven, and a precise control system ensures even pressure distribution, thereby guaranteeing the quality of the connection between the back cover and the phone casing.

[0004] However, in actual production, the loading and unloading of mobile phone back covers almost entirely rely on manual operation. Workers need to manually place the mobile phone back covers onto the pressing platform, and after pressing, manually remove the finished product. This reliance on manual operation not only increases the labor cost of the production line, but also significantly reduces the overall production efficiency of the production line.

[0005] In view of this, the inventor conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

[0006] This utility model provides a pressing fixture for pressing auxiliary materials for mobile phone back covers, aiming to solve the problem that existing equipment relies entirely on manual labor for loading and unloading, resulting in low efficiency.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A pressing fixture for pressing auxiliary materials for mobile phone back covers includes a machine base. With the length of the machine base as the left-right direction, a frame is provided on the front of the top of the machine base. A first pressing mechanism and a second pressing mechanism for pressing workpieces are provided on the frame. A loading station, a pick-and-place station, and a unloading station are arranged sequentially along the left-right direction on the rear side of the frame. A first feeding table and a second feeding table, which can alternately move between the pick-and-place station and the frame, are provided below the frame. A vertical frame is erected on the front of the top of the machine base. A sliding unit, which can move left-right, is provided on the side of the vertical frame facing the frame. Two spaced-apart suction claw units are erected on the front side of the sliding unit.

A first connecting block connected to the first synchronous belt is provided on one side of the first feeding table.

[0012] Furthermore, the aforementioned second belt drive system includes a third synchronous pulley and a fourth synchronous pulley arranged vertically at intervals. The third synchronous pulley and the fourth synchronous pulley are connected by a second synchronous belt drive, and a second motor for driving the rotation of the third synchronous pulley is provided below it. A second connecting block connected to the second synchronous belt is provided below the second feeding table.

[0013] Furthermore, the aforementioned sliding unit includes a slide rail disposed on the side of the aforementioned upright in the left-right direction, a sliding plate that slides in cooperation with the aforementioned slide rail, and a third cylinder that is fixedly disposed on one side of the aforementioned upright and can drive the aforementioned sliding plate to move left and right on the aforementioned slide rail. The aforementioned suction claw unit is provided on the front side of the aforementioned sliding plate.

[0014] Furthermore, the aforementioned suction claw unit includes an upright fixed plate, a bending plate disposed on the side of the fixed plate facing away from the sliding plate, a fourth cylinder disposed on the top of the fixed plate and capable of driving the bending plate to move up and down, and a connecting plate disposed on the bottom surface of the bending plate along the front-back direction.

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0027] Reference Figures 1 to 3A pressing fixture for pressing auxiliary materials for mobile phone back covers includes a machine base 10. With the length of the machine base 10 as the left-right direction, a frame 20 is provided on the front of the top of the machine base 10. The frame 20 is equipped with a first pressing mechanism 21 and a second pressing mechanism 22 for pressing the workpiece. The rear of the frame 20 is provided with a loading station 30, a pick-and-place station 40, and a unloading station 50 arranged sequentially in the left-right direction. In this embodiment, the loading station 30 and the unloading station 50 can be a loading conveyor belt (not shown in the figure) and an unloading conveyor belt (not shown in the figure). Below the frame 20 is a pick-and-place station... The first feeding table 61 and the second feeding table 62 alternately move between the position 40 and the frame 20. A stand 70 is erected on the front side of the top of the machine base 10. A sliding unit 80 that can move left and right is provided on the side of the stand 70 facing the frame 20. Two suction claw units 90 are erected on the front side of the sliding unit 80. One suction claw unit 90 can move the workpiece to be processed at the loading station 30 to the first feeding table 61 or the second feeding table 62. The other suction claw unit 90 can move the processed workpiece on the first feeding table 61 or the second feeding table 62 to the unloading station 50.

[0028] In application, the suction gripper unit 90 can send the mobile phone back cover to be processed at the loading station 30 into the first feeding table 61 or the second feeding table 62 for pressing processing, or send the processed mobile phone back cover on the first feeding table 61 or the second feeding table 62 moved to the pick-up and drop station 40 into the unloading station 50. The entire mobile phone back cover loading and unloading process is done without human intervention, which not only reduces labor costs, but also significantly improves the production efficiency of pressing processing.

[0029] Reference Figures 1 to 3The first pressing mechanism 21 includes a first cylinder 211 disposed on the top of the frame 20. The output end of the first cylinder 211 passes downward through the frame 20 and is fixedly mounted on a first pressure plate unit 212. The second pressing mechanism 22 includes a second cylinder 221 disposed on the top of the frame 20. The output end of the second cylinder 221 passes downward through the frame 20 and is fixedly mounted on a second pressure plate unit 222. The first pressure plate unit 212 includes a first connecting plate 213 and a first pressing plate 214 disposed below the first connecting plate 213. Multiple elastic buffers (not shown in the figure) are provided between the first pressing plate 212 and the first connecting plate 213. Multiple first connecting holes (not shown in the figure) are provided on the frame 20 at the top of the first connecting plate 213. Each first connecting hole is fitted with a vertically movable component. The first guide post 215, the bottom end of each first guide post 215 is fixedly connected to the first connecting plate 213; the second pressure plate unit 222 includes a second connecting plate 223 and a second pressure plate 224 disposed below the second connecting plate 223. The second pressure plate 224 and the second connecting plate 223 are provided with a plurality of elastic buffers (not shown in the figure), and the frame 20 at the top of the second connecting plate 223 is provided with a plurality of second connecting holes (not shown in the figure). Each second connecting hole is provided with a second guide post 225 that can move up and down. The bottom end of each second guide post 225 is fixedly connected to the second connecting plate 223. In this embodiment, the elastic buffer is a spring, which can provide a certain buffering effect during the pressing process to prevent excessive pressure from damaging the back cover of the mobile phone.

[0030] During the pressing process, the first pressing plate unit 212 and the second pressing plate unit 222 are controlled by the first cylinder 211 and the second cylinder 221, respectively, to perform the pressing operation. When the cylinder output end is pushed downward through the frame 20, the first pressing plate unit 212 and the second pressing plate unit 222 adjust the pressure through their elastic buffer (spring), so that the workpiece is subjected to uniform pressure distribution during the pressing process, thereby ensuring processing accuracy. In addition, the guide column structure of the first pressing plate unit 212 and the second pressing plate unit 222 ensures the precise up and down movement of each pressing unit, which not only prevents deviation during the pressing process, but also ensures the stability of each pressing plate, ensuring the uniformity and consistency of the pressing process.

[0031] Reference Figures 1 to 6The frame 20 has two first guide rails 23 arranged horizontally in the front-back direction below it, and two second guide rails 24 arranged horizontally in the front-back direction between the two first guide rails 23. A first feeding table 61 is provided on the first guide rail 23. The bottom of the first feeding table 61 is provided with a first guide block 611 for moving on the first guide rail 23, and a first belt drive system for driving the first feeding table 61 to move back and forth on the first guide rail 23 is provided on one side of the first guide rail 23. A second feeding table 62 is provided on the second guide rail 24. The bottom of the second feeding table 62 is provided with a second guide block 621 for moving on the second guide rail 24. A second belt drive system for driving the second feeding table 62 to move back and forth on the second guide rail 24 is also provided between the two second guide rails 24. In this embodiment, the height of the first feeding table 61 is higher than that of the second feeding table 62, and the bottom of the first feeding table 61 is provided with a passage space 612 for the second feeding table 62 to pass through.

[0032] Reference Figures 1 to 6 The first belt drive system includes a first mounting plate 251 and a second mounting plate 252 arranged at intervals. A first synchronous pulley 2511 and a second synchronous pulley 2521 are respectively mounted on the first mounting plate 251 and the second mounting plate 252. The first synchronous pulley 2511 and the second synchronous pulley 2521 are connected by a first synchronous belt 253. A first motor 254 for driving the first synchronous pulley 2511 to rotate is also mounted on the first mounting plate 251. A first connecting block 613 connected to the first synchronous belt 253 is provided on one side of the first feeding table 61. The second belt drive system includes a third synchronous pulley 261 and a fourth synchronous pulley 262 arranged vertically at intervals. The third synchronous pulley 261 and the fourth synchronous pulley 262 are connected by a second synchronous belt 263. A second motor 264 for driving the rotation of the third synchronous pulley 261 is also provided below it. A second connecting block 622 connected to the second synchronous belt 263 is provided below the second feeding table 62.

[0033] During application, the first belt drive system and the second belt drive system enable the feeding table to move smoothly back and forth on the guide rail. Since the height of the first feeding table 61 is higher than that of the second feeding table 62, and the bottom of the first feeding table 61 is provided with a passage space 612 for the second feeding table 62 to pass through, it can be ensured that the first feeding table 61 and the second feeding table 62 will not interfere with each other when they move alternately, thus improving the flexibility of equipment operation.

[0034] Reference Figures 1 to 8The sliding unit 80 includes a slide rail 81 arranged along the left-right direction on the side of the upright 70, a sliding plate 82, and a third cylinder 83 fixedly arranged on one side of the upright 70 and capable of driving the sliding plate 82 to move left and right on the slide rail 81. The rear side of the sliding plate 82 is provided with a translation block 821 that can move left and right on the slide rail 81, and the left side is provided with a protruding block 822 fixedly connected to the output end of the third cylinder 83. The front side is provided with a suction claw unit 90, which includes an upright fixed plate 91 and a third cylinder 83 fixedly arranged on the fixed plate 81. 1. An L-shaped bending plate 91 facing away from the sliding plate 82; a fourth cylinder 93 disposed on the top of the fixed plate 91 and capable of driving the bending plate 91 to move up and down; and a connecting plate 94 disposed on the bottom surface of the bending plate 91 along the front-back direction. At least one vacuum nozzle 95 for lifting or lowering the back cover of a mobile phone is symmetrically provided on both sides of the connecting plate 94 through a connector. In this embodiment, the connector can be a screw. The top of the vacuum nozzle 95 is provided with an air inlet (not shown in the figure) for connecting to an external air source. The external air source can be a vacuum pump.

[0035] During application, the sliding unit 80, driven by the third cylinder 83, causes the sliding plate 82 to move left and right on the slide rail 81. When the sliding plate 82 moves, the translation block 821 moves on the slide rail 81 to ensure the stable operation of the sliding plate 82. The protruding block 822 on the left side is connected to the output end of the third cylinder 83 to ensure the accuracy of the driving of the third cylinder 83. The suction claw unit 90, driven by the fourth cylinder 93, drives the bending plate 92 to move up and down, so that the vacuum nozzle 95 on the connecting plate 94 can pick up or put down the back cover of the mobile phone. The vacuum nozzle 95 is connected to an external air source (such as a vacuum pump) through the air inlet. When the air source is started, the vacuum nozzle 95 will generate suction to pick up the back cover of the mobile phone. After the operation is completed, the air source stops working and the vacuum nozzle 95 releases the back cover of the mobile phone.

[0036] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
