[0041] In view of the technical problems recorded in the background technology, such as Figure 1-2A vacuum transfer device for a mobile phone back cover is provided, comprising: a base 1, the base 1 being used to install and support mechanical parts; a linear moving device 2, the linear moving device 2 being installed on the base 1; a workbench 3, the workbench 3 being arranged on the linear moving device 2; the workbench 3 comprising a first working area 4 and a second working area 5 connected to the first working area 4; the first working area 4 and the second working area 5 being used for placing workpieces; a transfer device 6, the transfer device 6 being arranged on the base 1 and placed above the linear moving device 2, the transfer device 6 being used to transfer the workpieces on the first working area 4 and the second working area 5; a first workpiece placement rack 7, the first workpiece placement rack 7 being arranged on the base 1 and placed on the left side of the transfer device 6, the first workpiece placement rack 7 being used to place workpieces; a first transfer robot 8, the first transfer robot 8 being arranged on the left side of the first workpiece placement rack 7; the first transfer robot 8 The loading robot 8 is used to transfer the workpiece of the first workpiece placement rack 7 to the first working area 4, and the first transferring robot 8 is used to transfer the workpiece after transfer from the first working area 4 to the finished product conveying device 11; the second workpiece placement rack 9, the second workpiece placement rack 9 is arranged on the machine base 1 and placed on the right side of the transfer device 6, and the second workpiece placement rack 9 is used to place the workpiece; the second transferring robot 10, the second transferring robot 10 is arranged on the right side of the second workpiece placement rack 9; the second transferring robot 10 is used to transfer the workpiece of the second workpiece placement rack 9 to the second working area 5, and the second transferring robot 10 is used to transfer the workpiece after transfer from the second working area 5 to the finished product conveying device 11; the finished product conveying device 11, the finished product conveying device 11 is arranged on one side of the transfer device 6, and the finished product conveying device 11 is used to transport the transferred workpiece; the control system, the control system is used to receive and output signals.

[0042] In the above, the control system can adopt a numerical control system or a PLC control system to accurately control the movement and operation of the mechanical components through digital instructions. The base 1 is formed by a base made of metal profiles. In practice, the design can be adapted according to actual use needs and is not limited to this.

[0043] The workbench 3 is composed of a first work area 4 and a second work area 5. The first work area 4 and the second work area 5 are used to place workpieces. In actual work, if the first work area 4 is in the transfer device 6 to transfer the workpiece pattern, the workpiece transferred from the second work area 5 is transferred to the finished product conveying device 11 by the second transfer robot 10, and the second transfer robot 10 transfers the workpiece on the second workpiece placement rack 9 to the second work area 5; after the workpiece of the first work area 4 is transferred, under the action of the linear moving device 2, the first work area 4 moves to the position of the first transfer robot 8, and the workpiece transferred from the first work area 4 is transferred to the finished product conveying device 11 by the first transfer robot 8, and the first transfer robot 8 transfers the workpiece on the first workpiece placement rack 7 to the first work area 4. This is repeated, and the first work area 4 and the second work area 5 are rotated. The transfer device 6 is in a five-no-load state, which greatly improves production efficiency.

[0044] The usage process is as follows: the workpiece can be the back cover of a mobile phone, which is pre-sprayed with paint. The pre-sprayed paint workpiece is manually placed on the first workpiece placement rack 7 and the second workpiece placement rack 9. At this time, the first working area 4 is located on one side of the first transfer robot 8, and the second working area 5 is located on the transfer device 6 for transfer work. The first transfer robot 8 transfers the workpiece transferred from the first working area 4 to the finished product conveying device 11. The first transfer robot 8 transfers the workpiece on the first workpiece placement rack 7 to the first working area 4. When the workpiece transfer at the second working area 5 is completed, the second working area 5 is driven by the linear moving device 2 to move to the side of the second transfer robot 10. The first working area 4 moves to the transfer device 6 for transfer work. The second transfer robot 10 transfers the workpiece transferred from the second working area 5 to the finished product conveying device 11. The second transfer robot 10 transfers the workpiece on the second workpiece placement rack 9 to the second working area 5, thereby realizing the transfer operation of the workpiece in a reciprocating manner.

[0045] In the above example, the workbench 3 utilizes a first work area 4 and a second work area 5, coupled with a double-sided transfer manipulator and workpiece placement rack, enabling simultaneous loading and unloading of workpieces and rubbing operations, significantly improving production efficiency. Alternating operation of the two work areas reduces idle time and significantly increases production efficiency.

[0046] refer to Figure 3 As shown, the linear moving device 2 includes a first motor 12 mounted on the machine base 1, a first lead screw 13 arranged on the output end of the first motor 12, and a linear guide rail 14 arranged parallel to the first lead screw 13; wherein, the workbench 3 is mounted on the first lead screw 13 through a lead screw nut, and the workbench 3 is connected to the linear guide rail 14.

[0047] As a preferred embodiment, the linear moving device 2 includes a first motor 12, a first lead screw 13 and a linear guide 14. Two pairs of linear guides 14 are used, and the linear guides 14 are respectively placed on both sides of the first lead screw 13. The specific driving process is: the first motor 12 drives the first lead screw 13 to rotate. Since the workbench 3 is mounted on the first lead screw 13 through a lead screw nut, and the workbench 3 is connected to the linear guide 14, the rotational motion of the first lead screw 13 is converted into movement of the workbench 3 along the linear guide 14.

[0048] like Figure 4-7 As shown, the first working area 4 includes a first cavity 15, a first guide rail 16 arranged on the inner wall of the first cavity 15, a first lower mold 17 and a second lower mold 18 connected to the first guide rail 16, a first lifting member 19 connected to the lower part of the first lower mold 17, a second lifting member 20 connected to the lower part of the second lower mold 18, a first guide rod group 21 connected to the lower part of the first lower mold 17, and a second guide rod group 22 connected to the lower part of the second lower mold 18; the second working area 5 includes a second cavity 23, a second guide rail 24 arranged on the inner wall of the second cavity 23, a third lower mold 25 and a fourth lower mold 26 connected to the second guide rail 24, a third lifting member 27 connected to the lower part of the third lower mold 25, a fourth lifting member 28 connected to the lower part of the fourth lower mold 26, a third guide rod group 29 connected to the lower part of the third lower mold 25, and a fourth guide rod group 30 connected to the lower part of the fourth lower mold 26.

[0049] In order to improve production efficiency, multiple workpieces need to be transferred simultaneously, that is, multiple mold cavities are provided on the lower mold. Since the traditional lower mold structure adopts a single lower mold, the mold closing requirements of the single lower mold and the upper mold 33 are high, resulting in high processing precision of the single lower mold and difficulty in processing. At the same time, the defective rate of workpieces transferred from the single lower mold with poor processing precision is high.

[0050] In this regard, the structure of the first working area 4 includes a first cavity 15 with an upward opening, a first guide rail 16, a first lower mold 17, a second lower mold 18, a first lift 19, a second lift 20, a first guide rod group 21 and a second guide rod group 22. The first lower mold 17 and the second lower mold 18 are designed according to the workpiece to be processed and are used to place the workpiece. A first guide rail 16 is set in the first cavity 15. The first guide rail 16 is used to improve the stability and accuracy of the longitudinal movement of the first lower mold 17 and the second lower mold 18. The first guide rail 16 is set longitudinally, and the number of first guide rails 16 can be selected according to the specific implementation situation. The first lower mold 17 and the second lower mold 18 can slide on the first guide rail 16 through a slider. The first lift 19 and the second lift 20 are used for the mold closing operation of the first lower mold 17 and the second lower mold 18. The first lift 19 and the second lift 20 can be selected from telescopic components such as oil cylinders or air cylinders that meet the mold closing requirements. The first guide rod group 21 and the second guide rod group 22 are in the form of multiple optical axes, for example, four optical axes, for guiding movement and sharing loads.

[0051] The specific driving process is as follows: the first lifting member 19 and the second lifting member 20 respectively drive the first lower mold 17 and the second lower mold 18 to move longitudinally to close the mold. During this longitudinal movement, they move under the guidance of the first guide rail 16. The second working area 5 is composed of a second cavity 23 with an upward opening, a second guide rail 24, a third lifting member 27, a fourth lifting member 28, a third guide rod group 29, and a fourth guide rod group 30. Its operating process and design principles are the same as those of the first working area 4. Please refer to the first working area 4 above and will not be repeated here.

[0052] In the above technical solution, two lower molds are used in any working area. Compared with the traditional single lower mold, the number of mold cavities on the two lower molds can be the same as the number of mold cavities of a single lower mold, that is, the number of workpieces processed simultaneously is the same. Moreover, since two lower molds are used in this technical solution, the processing accuracy is lower than that of a single lower mold, and the processing process is more convenient. At the same time, a guide rail is provided in the cavity, which can improve the stability of the two lower molds during the movement process and the accuracy during the mold closing process. Moreover, the provision of two working areas can realize the alternating rotation of the two working areas during the driving process, reducing the idle time of the equipment and thereby improving work efficiency.

[0053] refer to Figure 8-11As shown, the transfer device 6 includes a frame 31 installed on the machine base 1, a fifth guide rod group 32 installed on the frame 31, an upper mold 33 sleeved on the fifth guide rod group 32, a fifth lifting member 34 arranged on the frame 31 and connected to the upper mold 33 at the output end, a first UV lamp 35 arranged above the upper mold 33, a vacuum pump 36 installed on the machine base 1 and a vacuum pipe 37 connected to the vacuum pump 36; wherein, the vacuum pipe 37 extends to the frame 31, and the vacuum pipe 37 is used to connect with the first cavity 15 and the second cavity 23 for vacuum extraction; the first UV lamp 35 is used to irradiate and cure the workpiece on the lower mold through the upper mold 33.

[0054] The frame 31 is provided to accommodate the mounting of the various mechanical components of the transfer device 6. The fifth guide rod assembly 32 utilizes multiple optical axes, for example, four, to guide movement and share loads. The upper mold 33 is designed to close the first and second lower molds 17, 18, and the third and fourth lower molds 25, 26. The fifth lift 34 can be a hydraulic or pneumatic cylinder, or other retractable component that meets the mold closing requirements. The first UV lamp 35 is used to illuminate the workpiece on the lower mold through the upper mold 33, curing the pre-applied paint on the workpiece.

[0055] The specific working process is as follows: driven by the linear motion device 2, the first working area 4 moves to below the transfer device 6. The first and second lifting members 19 and 20 of the first working area 4 drive the first and second lower molds 17 and 18 to move longitudinally. Simultaneously, the fifth lifting member 34 drives the upper mold 33 to move longitudinally to close the molds 17 and 18. The vacuum pipe 37 is connected to the reserved hole in the first cavity 15. The vacuum pump 36 drives the first cavity 15 to evacuate the vacuum, and then the first UV lamp 35 drives the workpiece to cure the paint. After the transfer operation is completed, the vacuum pump 36 stops evacuating the first cavity 15. The fifth lifting member 34 then drives the upper mold 33 to reset. The linear motion device 2 drives the second working area 5 to below the transfer device 6. The first working area 4 moves to the first transfer robot 8 to move the transferred workpiece. The transfer device 6 repeats the above operation for the workpiece in the second working area 5.

[0057] The first workpiece placement frame 7 is used to place workpieces. The sixth guide rod assembly 39 can be in the form of multiple optical axes, for example, four optical axes, for connecting the first base plate 38 and the first placement plate 40. The first placement plate 40 can be adjusted in height relative to the first base plate 38 and then fixed. The first placement plate 40 is configured to accommodate the number of workpieces to be placed. For example, when sucking four workpieces at a time, four first workstations 41 can be provided on the first placement plate 40.
