[0002] The mainstream technology currently used in the front-end packaging of our company is flip-chip mounting technology, which realizes the communication function through the welding of the substrate and the chip. First, the SUB substrate is placed on a specific Jig base, and then enters the placement machine for chip mounting and welding. After completion, the product and the JIG are separated. However, in the separation process, affected by product iterations, the SUB substrate of the iterative product will become thinner and thinner, resulting in stronger and stronger magnetic force between the JIGs.

[0043] The utility model provides a device for separating assembled products, which is used in the process of separating assembled products. The utility model does not limit the type of products, but the structure of the device for separating assembled products is particularly suitable for separating products and bases in flip-chips.

[0044] In general, the device for separating assembled products proposed in the present invention mainly includes a vacuum suction cup assembly, a sensor 1, a manipulator 2 and a drive unit. Figure 1 , which shows the arrangement relationship of the vacuum suction cup assembly, the sensor 1, the manipulator 2 and the driving unit.

[0045] In order to achieve the purpose of changing the separation mode and the hardware design and stability of the separation mode change, and to solve the problem in the background technology that different processes such as stamping and forming need to be replaced with different machine models and molds, in the technical solution provided in this embodiment, a pair of manipulators 2 are installed front and back on the basis of the vacuum suction cup assembly, and the up and down moving module 10 and the balancing clamping cylinder 11 of the driving manipulator 2 are used to achieve the purpose of adjusting the height and grasping position corresponding to different JIG adaptability, effectively replace vacuum adsorption separation, and completely solve the problems caused by vacuum adsorption abnormalities. While achieving physical separation, the coordination of the sensor 1 is used to quickly feedback the effect of grasping the JIG, and stably and effectively achieve the purpose of improving the separation effect.

[0046] Specifically, Figure 1As shown, the vacuum suction cup assembly is arranged at the bottom, and the JIG to be separated is adsorbed at the bottom. A manipulator 2 is installed on the top of the vacuum suction cup assembly through a connecting plate assembly. A pair of manipulators 2 are arranged front and back along the axial direction of the vacuum suction cup assembly and are connected to a driving unit. During use, the driving unit drives the manipulator 2 to separate and adjust the up and down positions. The inner side of the bottom of the manipulator 2 is a stepped structure and is bent toward the internal JIG. During the separation process, the bottom of the manipulator 2 contacts the JIG to be separated to achieve the effect of separating the JIG. During the separation, since the sensor 1 is installed at one end of the axial direction of the vacuum suction cup assembly, the direction of the sensor head corresponds to the JIG to be separated at the bottom, and can be bound to the device through the sensor 1. When the signal of the sensor 1 is abnormal, such as a height difference, the device receives the signal, alarms and automatically stops the operation.

[0047] As mentioned above, the vacuum suction cup assembly provided in this embodiment includes an air circuit mounting plate 3 and a vacuum suction cup 4 installed below the air circuit mounting plate 3. Since the four sides of the air circuit mounting plate 3 are larger than the size of the vacuum suction cup 4, the sensor 1 can be installed on one axial side of the vacuum suction cup 4, and the sensing head of the sensor 1 faces the JIG below to detect the separation status in real time; in addition, a No. 1 groove 5 is provided on both side surfaces of the air circuit mounting plate 3 perpendicular to the installation position of the sensor 1 corresponding to the manipulator 2. When the equipment is in the initial state, the outer side surface of the manipulator 2 is located in the No. 1 groove 5, which can effectively protect the manipulator 2.

[0048] It should be specifically explained that the manipulator 2 is installed on the top of the vacuum suction cup assembly through a connecting plate assembly, and the connecting plate assembly is sequentially provided with a lower connecting plate 6 and an upper connecting plate 8 along the top of the air path mounting plate 3, and the upper connecting plate 8, the lower connecting plate 6 and the air path mounting plate 3 are arranged in parallel and fastened by bolts passing through the center axis; specifically, since the connecting plate assembly is a structural member added after the vacuum suction cup assembly, on the basis of being fastened by bolts, in order to facilitate disassembly and ensure stability after installation, the lower connecting plate 6 is arranged in parallel above the air path mounting plate 3, and the two are fastened and disassembled by a lock buckle 7; in addition, as shown in the accompanying drawings, a driving unit for driving the manipulator 2 to move is installed on the connecting plate assembly, and the driving unit will generate vibration during movement, but the influence of the vibration on the vacuum suction cup assembly should be avoided, so on the basis of the upper connecting plate 8 being arranged in parallel above the lower connecting plate 6, it is preferred that a gap is set between the two through a buffer bolt 9, and a spring 15 is provided on the outer sleeve of the buffer bolt 9, and the spring 15 is used to offset the direct influence from the driving unit, and also eliminate the influence of the bottom JIG adsorption and removal.

[0049] On this basis, it is considered to make the manipulator 2 as universal as possible. For this purpose, a driving unit is installed on the connecting plate assembly to realize the adjustment of the manipulator 2 in the vertical and horizontal directions, wherein the up and down moving module 10 in the driving unit is vertically installed on the top of the upper connecting plate 8, and then the vertical side of the balancing jaw cylinder 11 is connected to the slider of the up and down moving module 10, and the position is adjusted up and down with the movement of the up and down moving module 10. The bottom claw of the balancing jaw cylinder 11 passes through the upper connecting plate 8 and is connected to the manipulators 2 on both sides, thus realizing the effect of adjusting the up and down position and the horizontal opening and closing position of the manipulator 2 by the driving unit, which can achieve the effect of matching JIGs of various sizes, with a high degree of automation and high effect.

[0050] However, considering the reasonable arrangement of the manipulator 2 integrated on the connecting plate assembly and the vacuum suction cup assembly and the driving unit driving the manipulator 2, on the one hand, a groove 5 is provided on both sides of the gas path mounting plate 3 perpendicular to the installation position of the sensor 1, corresponding to the manipulator 2. Similarly, the surrounding dimensions of the connecting plate assembly are smaller than the dimensions of the gas path mounting plate 3, and the manipulator 2 is arranged at the position of the size difference, and the avoidance structure in the size structure is used to achieve the effect of providing the installation position of the manipulator 2, while also avoiding the protruding installation effect of the manipulator 2, thereby playing an effective protective role;

[0051] On the other hand, since the bottom claw of the balancing jaw cylinder 11 is vertically arranged, in order to achieve the effect of horizontal movement of the manipulator 2 toward both sides, the bottom claw and the manipulator 2 are connected by an L-shaped connector 12. The vertical end of the L-shaped connector 12 is installed on the bottom claw, and the horizontal end is connected to the manipulator 2. It can be seen from the accompanying drawings that the above structure is bound to pass through the upper connecting plate 8 and the lower connecting plate 6. For this purpose, the upper connecting plate 8 is located between the buffer bolt 9 and the up and down moving module 10. A through hole 14 is provided on the structure that passes through the bottom claw of the balancing jaw cylinder 11. At the same time, the structural thickness of the upper connecting plate 8 and the lower connecting plate 6 located between the manipulators 2 on both sides is less than the thickness of the remaining structures, and a space for accommodating the guide rail 13 and the L-shaped connector 12 is formed between the two.

[0052] On this basis, the present embodiment also provides a guide rail structure for guiding the horizontal movement of the manipulator 2, wherein the horizontal end of the L-shaped connecting piece 12 is connected to the guide rail 13 below through a slider, and a corresponding second groove 16 for installing the guide rail 13 is provided on the structure of the lower connecting plate 6 located between the manipulators 2 on both sides, and the guide rail 13 is installed on the lower connecting plate 6. When in use, the manipulator 2 moves horizontally in a straight line toward both sides along the direction of the guide rail 13, which is also beneficial for a pair of manipulators 2 on the left and right sides to form a structure suitable for JIG at the bottom, so that the JIG will not be damaged.

[0053] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
