In the die bonding process, the chip is usually required to be transferred, and the transferring process usually adopts a mode of connecting a suction nozzle through a mechanical arm and then sucking the chip by using the suction nozzle. Specifically, the suction nozzle comprises a suction nozzle head and a suction nozzle body, a binding head is arranged at one end of the mechanical arm generally, a containing cavity matched with the suction nozzle body is formed in the binding head, and the mechanical arm generally sucks the suction nozzle body into the containing cavity to realize detachable connection of the mechanical arm and the suction nozzle when the suction nozzle is replaced. When the chip is sucked, the mechanical arm needs to move the suction nozzle head to the upper part of the chip, and then the mechanical arm is controlled to enable the suction nozzle head to contact the chip, and at the moment, the suction nozzle can generate suction force which is enough to suck the chip by controlling the air pressure change in the accommodating cavity. The chip is sucked by the suction nozzle and then the mechanical arm is operated, so that the chip transferring work can be completed.

However, the nozzle holders of the prior art are usually arranged in a fixed position. In the die bonding process, a mechanical arm is usually operated to suck the chips at the preset positions and then transfer the chips to a workbench. The chip has different types, and the chip with different types is usually adapted by adopting the suction nozzles with different types. Secondly, when transferring chips of the same type, the nozzles need to be replaced appropriately after the nozzles are sucked for a long time. When the suction nozzle is replaced, the position of the suction nozzle frame needs to be positioned, and the mechanical arm moves from the workbench to the position of the suction nozzle frame. And secondly, the position of the suction nozzle on the suction nozzle frame is required to be positioned, and then the mechanical arm is moved to the position above the required suction nozzle to replace the suction nozzle. After the suction nozzle is replaced, the mechanical arm needs to move to the upper part of the chip to be moved from the suction nozzle frame at the fixed position, and then the chip is transferred to the workbench by adopting the replaced suction nozzle.

In order to solve the above-mentioned problems, referring to fig. 1, an embodiment of the utility model provides a suction nozzle carrying device 1 for carrying suction nozzles, the suction nozzle carrying device 1 includes a base 12, a workbench 11 and a suction nozzle frame 13, and the workbench 11 is disposed on the base 12 and can be movably connected with the base 12.

The nozzle rack 13 includes a connecting member 131 and a carrying platform 130, wherein one side of the carrying platform 130 is defined as a carrying surface 130a, at least one accommodating groove 132 is formed along the direction perpendicular to the carrying surface 130a to accommodate the nozzles, and the connecting member 131 is respectively connected to the working platform 11 and the carrying platform 130, so that the nozzle rack 13 can move along with the working platform 11 on the base 12.

It will be appreciated that the carrying platform 130 of the nozzle rack 13 is fixed to the table 11 through the connecting member 131, and when the table 11 moves, the nozzle rack 13 moves along with the movement of the table 11, i.e. the positions of the table 11 to the carrying platform 130 for carrying the nozzles are relatively fixed. When the mechanical arm needs to replace the suction nozzles for chips of different types, the mechanical arm moves from the upper part of the workbench 11 to the bearing table 130, puts down the original suction nozzles on the mechanical arm, and moves to the upper part of the accommodating groove 132 to suck the suction nozzles accommodated in the accommodating groove 132. Then the mechanical arm moves to the upper part of the chip to be moved, and the chip is sucked and transferred to the workbench 11 to finish the transfer work of the chip. It should be appreciated that since the positions of the work table 11 to the carrying table 130 carrying the suction nozzles are relatively fixed, the time consumed by the robot arm in exchanging the suction nozzles is reduced, and the work efficiency is improved.

It should be noted that at least one receiving groove 132 is formed along the direction perpendicular to the bearing surface 130 a. It should be appreciated that the type of nozzle received in the receiving slot 132 may be the same or different from the type of nozzle currently connected to the robotic arm. When the types of the suction nozzles are different, the mechanical arm can replace the suction nozzles with different types on the suction nozzle frame 13 so as to suck the chips with different types. When the types of the suction nozzles are the same, the mechanical arm can replace the suction nozzles of the same type in time to work in the working process, so that the phenomenon that the suction nozzles deform and cannot suck chips after long-time working is avoided.

Further, at least two receiving grooves 132 are provided along the length direction and/or the width direction of the bearing surface 130a, and the receiving grooves 132 may be used to receive different types or the same type of suction nozzles.

Referring to fig. 1 and 2, the carrier 130 is shown to be provided with at least two receiving grooves 132 along the length of the carrying surface 130a thereof, and the receiving grooves 132 can be used to receive different types of suction nozzles.

Referring to fig. 1 and 3, the carrier 130 is shown to be provided with at least two receiving grooves 132 along the length of the carrying surface 130a thereof, and the receiving grooves 132 can be used to receive different types of suction nozzles.

Referring to fig. 1 and 4, there are shown that the carrying platform 130 is provided with at least two receiving grooves 132 along the length direction and the width direction of the carrying surface 130a thereof, and the receiving grooves 132 can be used for receiving different types of suction nozzles.

It should be understood that at least two accommodating grooves 132 are provided on the carrying surface 130a, and the types of the suction nozzles on the accommodating grooves 132 are different, so that when chips of different types exist in the chip transferring process, the mechanical arm can replace the suction nozzles of different types on the suction nozzle frame 13 to suck the chips of different types.

Referring to fig. 1 and 5, the carrier 130 is shown to be provided with at least two receiving grooves 132 along the length of the carrying surface 130a thereof, the receiving grooves 132 being adapted to receive the same type of suction nozzle.

Referring to fig. 1 and 6, there are shown that the loading table 130 is provided with at least two receiving grooves 132 along the width direction of the loading surface 130a thereof, and the receiving grooves 132 can be used to receive the same type of suction nozzles.

Referring to fig. 1 and 7, there are shown that the loading table 130 is provided with at least two receiving grooves 132 along the length direction and the width direction of the loading surface 130a thereof, and the receiving grooves 132 can be used to receive the same type of suction nozzles.

It should be understood that at least two accommodating grooves 132 are provided on the carrying surface 130a, and the types of the suction nozzles on the accommodating grooves 132 are the same, when the chips with the same type are transferred, the suction nozzles on the mechanical arm are affected by the suction force for a long time and deform, so that the suction force provided by the suction nozzles cannot suck and transfer the chips. And the bearing surface 130a is provided with at least two accommodating grooves 132 which accommodate at least two suction nozzles of the same type, so that the mechanical arm can conveniently replace the suction nozzles in a proper time, and the chip transferring process can not be influenced by deformation of the suction nozzles.

Further, referring to fig. 1 and 8, the carrying platform 130 includes a bottom surface 130b opposite to the carrying surface 130a and two opposite side surfaces 130c connected to the carrying surface 130 a; the accommodating groove 132 includes a first accommodating groove 1321 and a second accommodating groove 1322, the first accommodating groove 1321 and the second accommodating groove 1322 are formed along the direction perpendicular to the bearing surface 130a, and the groove wall communicating side 130c of the first accommodating groove 1321 forms a mating opening 1323 for the suction nozzle to pass through; both ends of the connection member 131 are connected to the bottom surface 130b and the table 11, respectively.

Specifically, the first and second receiving grooves 1321 and 1322 respectively receive different types of suction nozzles. The first receiving groove 1321 has a substantially semicircular cross-sectional shape, and when the suction nozzle is placed in the first receiving groove 1321, the suction nozzle can be placed in the second receiving groove 1322 through the fitting opening 1323 in a direction parallel to the bearing surface 130 a. Is simple and convenient. Specifically, when the suction nozzle is placed in the second accommodating groove 1322, the suction nozzle needs to be placed in the second accommodating groove 1322 along the axial direction of the second accommodating groove 1322 on the side of the bearing surface 130a defined by the bearing table 130. It should be appreciated that by providing the first receiving groove 1321 and the second receiving groove 1322, different types of nozzles may be accommodated in the first receiving groove 1321 and the second receiving groove 1322, so that the mechanical arm may correspondingly replace different types of nozzles according to different types of chips, and the manners of picking and placing the nozzles in the first receiving groove 1321 and the second receiving groove 1322 are different, so that the manners of picking and placing the nozzles are diversified in the picking and placing process.

Preferably, the first receiving groove 1321 is disposed at an end of the carrying surface 130a away from the table 11. It should be understood that the slot wall communicating side 130c of the first receiving slot 1321 forms a fitting opening 1323 through which the suction nozzle can pass, and the opening direction of the fitting opening 1323 is the same as the direction in which the loading table 130 is away from the table 11. Since fewer devices are provided on the base 12 in the direction in which the carrying table 130 is away from the table 11, the robot arm is not easily interfered by other devices during the movement when the suction nozzle is replaced in the first receiving groove 1321.

Further, a side of the table 11 away from the base 12 is defined as a working surface 110, and the working surface 110 is parallel to the bearing surface 130 a. It should be appreciated that the work surface 110 carries a substrate, which may be, for example, any of a PCB board, a silicon substrate, a charged dielectric plate, a metal substrate, or a flexible circuit board. Specifically, the mechanical arm can attach the chip to the substrate after sucking the chip at a preset position through the suction nozzle. To ensure flatness and accuracy during die attach, the die surface and the work surface 110 at the predetermined location are generally substantially parallel. In the prior art, since the surface of the suction nozzle frame 13 is not parallel to the working surface 110 of the workbench 11, when the mechanical arm changes the suction nozzle, the angle between the mechanical arm and the surface of the suction nozzle frame 13 needs to be adjusted first, so that the mechanical arm can suck the suction nozzle body 111 into the accommodating cavity for the Ji Xizui body 111.

Referring to fig. 1, in the present embodiment, the working surface 110, the carrying surface 130a and the chip surface at the preset position are relatively parallel to each other, so that the mechanical arm moves back and forth between the three surfaces, and the angles between the mechanical arm and the three surfaces do not need to be repeatedly adjusted during the process of sucking the chip and replacing the suction nozzle, thereby greatly improving the working efficiency of the mechanical arm.

Specifically, referring to fig. 9, the workbench 11 includes a body 111, a driving motor 112 and a transmission device 113, wherein the body 111 is movably connected with the base 12, a containing space with an opening is defined in the body 111, and the transmission device 113 is disposed in the containing space and is close to the opening; the side of the transmission device 113 away from the base 12 is used for carrying a substrate, and the driving motor 112 is disposed on one side of the body 111 and electrically connected to the transmission device 113 to drive the transmission device 113 to operate to transmit the substrate. It should be understood that, the two ends of the body 111 corresponding to the conveying device 113 are respectively provided with the feeding port 1112 and the discharging port 1113, in the chip mounting process, the substrate enters the conveying device 113 from the feeding port 1112, the driving motor 112 drives the conveying device 113 to move the substrate towards one side of the discharging port 1113, at this time, the mechanical arm can absorb the chip by the suction nozzle to mount the chip onto the substrate, and the mounted substrate can be output from the discharging port 1113 to complete the mounting work of the substrate.

Specifically, the transmission device 113 includes a transmission belt 1131 and a limiting frame 1132, the limiting frame 1132 is disposed near the opening, the transmission belt 1131 is accommodated in the accommodating space, two ends of the transmission belt 1131 are respectively connected with the feeding port 1112 and the discharging port 1113, a top column 1133 is disposed on one side of the transmission belt 1131 near the limiting frame 1132, and the limiting frame 1132 corresponds to the top column 1133 and is provided with a limiting port 11321.

It should be appreciated that when the substrate enters the conveyor 113 through the inlet 1112, the drive motor 112 drives the conveyor 1131 to move the substrate toward the outlet 1113, and when the substrate moves to the top column 1133, the drive motor 112 controls the conveyor 1131 to stop. At this time, the top column 1133 moves towards the direction close to the limiting opening 11321, and applies an acting force to the substrate, so that the substrate follows the top column 1133 to stretch out and move towards the direction of the limiting opening 11321 together until the substrate moves to the position of the limiting opening 11321, and at this time, the limiting opening 11321 can limit the substrate. The mechanical arm sucks the chip through the suction nozzle to attach the chip to the substrate. Due to the limiting effect of the limiting opening 11321, the substrate is more stable during mounting, and the stability of the mounting process is improved. After the mounting is completed, the top column 1133 performs shrinkage movement in a direction away from the limit opening 11321, so that the substrate returns to the conveyor 1131 again, and the driving motor 112 continues to drive the conveyor 1131 to work, so that the mounted substrate can be output from the discharge opening 1113.

It should be noted that, referring to fig. 10, the body 111 may move along the length direction of the nozzle frame 13 or along the width direction of the nozzle frame 13 relative to the base 12. It should be understood that the body 111 and the base 12 are movably connected, please refer to the figure together, the length direction of the suction nozzle frame 13 is defined as x, the width direction of the suction nozzle frame 13 is defined as y, the body 111 can move relative to the base 12 in a plane formed by the x axis and the y axis, it should be understood that chips of different types may be located at different positions during the mounting process, and the workbench 11 can move relative to the base 12, so that the workbench 11 can adaptively move to the corresponding position according to different positions of the chips, thereby effectively improving the efficiency of chip mounting.
