Description

TECHNICAL FIELD

[0001] The present application relates to the dispensing technology field, especially to a multi-track dispensing operation device and a dispensing operation method thereof. BACKGROUND

[0002] Underfill dispensing is a common post-sealing and testing process in semiconductor manufacturing. The traditional dispensing machine dispenses the product carried on the carrier for the first time, and then dispenses the product again after the glue on the product fills the gap between the chip and the substrate. This cycle is repeated to complete the multiple dispensing operations of the product.

[0003] In the traditional process, since the chip size is small, multiple chips can be distributed on a single carrier. However, as the size of high-performance chips continues to increase, the number of chips that can be carried on a single carrier gradually decreases. Moreover, due to the excessive size of the chip, the time required for the glue to flow and fill the gap between the chip and the substrate after completing a dispensing operation is significantly prolonged. More importantly, most existing dispensing machines use a single-track operation mode. When the chip on the track completes a dispensing operation, the dispensing execution module has to wait because the glue has not yet fully filled the gap. This undoubtedly causes a waste of time. Therefore, as the size of high-performance chip packaging continues to increase and the underfill delay time increases, the production capacity of a dispensing machine is significantly reduced. If we want to improve production efficiency, we need to increase multiple dispensing machines, but increasing multiple dispensing machines increases the floor space occupied by the machine and increases the cost, which poses a challenge to the current production workshop space layout. SUMMARY

[0004] The technical problem solved by the present application is the low production efficiency, large floor space occupied by the machine, and high cost.

[0005] Therefore, the present application provides a multi-track dispensing operation device and a dispensing operation method thereof to improve the production efficiency of large chip product underfill process and reduce the floor space occupied by a single machine.

[0006] The multi-track dispensing operation device according to an embodiment of the present application comprises: an upper feeding device, a dispensing device, and a lower feeding device arranged in sequence along the workpiece conveying direction;

[0007] The dispensing device comprises a left dispensing mechanism, a right dispensing mechanism, and a plurality of operation conveying mechanisms. The plurality of operation conveying mechanisms are arranged in parallel. The left dispensing mechanism and the right dispensing mechanism are oppositely arranged and cross-set above the plurality of operation conveying mechanisms, and the cross-set direction is perpendicular to the workpiece conveying direction.

[0008] Each of the workpiece conveying mechanisms is provided with a left work area and a right work area along a workpiece conveying direction, the left work area is close to the feeding device, the right work area is away from the feeding device relative to the left work area and close to the discharging device, the left dispensing mechanism performs dispensing work on the workpiece conveyed to the left work area, the right dispensing mechanism performs dispensing work on the workpiece conveyed to the right work area, and based on the workpiece conveying direction, a workpiece to be processed is preferentially conveyed to the right work area, and then another workpiece to be processed is conveyed to the left work area;

[0009] The feeding device is used for conveying the workpieces to be processed to any of the workpiece conveying mechanisms, and conveying two workpieces to be processed to the same workpiece conveying mechanism in sequence;

[0010] The left dispensing mechanism is used for sequentially performing dispensing work on the workpieces conveyed to the multiple left work areas;

[0011] The right dispensing mechanism is used for sequentially performing dispensing work on the workpieces conveyed to the multiple right work areas;

[0012] The discharging device is used for receiving the two workpieces that have completed dispensing work on any of the workpiece conveying mechanisms, and preferentially receiving the workpiece on the right work area and then receiving the workpiece on the left work area.

[0013] The present application has the beneficial effect that by arranging multiple parallel workpiece conveying mechanisms, each of which is provided with a left work area and a right work area, the dispensing work area of the single dispensing device is correspondingly increased, the two dispensing mechanisms are independent of each other, the left dispensing mechanism performs dispensing work on the workpieces in multiple left work areas, and the right dispensing mechanism performs dispensing work on the workpieces in multiple right work areas, each dispensing mechanism can fully utilize the time required for filling the dispensing gap in the current work area to perform dispensing work in other work areas, avoid idle waiting time of the device, and improve production efficiency.

[0014] According to one embodiment of the present application, the right dispensing mechanism moves to the right work area of one of the workpiece conveying mechanisms through the three-axis motion mechanism, and after sequentially performing dispensing work on multiple workpieces conveyed to the right work area and during the waiting time for performing the next dispensing work, the right dispensing mechanism can move to the right work area of another workpiece conveying mechanism through the three-axis motion mechanism, and sequentially perform dispensing work on multiple workpieces in the right work area;

[0015] When the left dispensing mechanism moves to the left work area of one of the work conveying mechanisms through the three-axis movement mechanism and completes dispensing work on the multiple workpieces conveyed to the left work area and is in a waiting time for executing the next dispensing work, the left dispensing mechanism can move to the left work area of another work conveying mechanism through the three-axis movement mechanism and execute dispensing work on the multiple workpieces in the left work area. Thus, when the dispensing mechanism completes dispensing work and is in an idle period for executing the next work, the dispensing mechanism does not idle and wait, but moves to the corresponding work area of the other work conveying mechanism to continue to execute dispensing work. The dispensing mechanism can process more workpieces by using the bottom filling delay time of the adhesive, avoids idle waiting time of the equipment, improves the overall production efficiency, and the left dispensing mechanism and the right dispensing mechanism can operate according to this mode, increase the dispensing work quantity of a single machine, and improve the production efficiency of the bottom filling process of large-die chip products.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0063] As Figures 1 to 18 shown is a preferred embodiment of the present application, the multi-track dispensing operation equipment of the embodiment comprises: a feeding equipment 2, a dispensing equipment 1 and a discharging equipment 3 arranged in sequence along the workpiece conveying direction; the workpiece conveying direction of the embodiment is the x-axis direction;

[0064] The dispensing device 1 comprises a left dispensing mechanism 102, a right dispensing mechanism 101 and four work conveying mechanisms 103, the four work conveying mechanisms 103 are arranged in parallel along the y-axis direction, the right dispensing mechanism 101 and the left dispensing mechanism 102 are oppositely arranged and cross the four work conveying mechanisms 103 along the y-axis direction, each work conveying mechanism 103 has a right work area 104 and a left work area 105 arranged in sequence along the x-axis direction, the left work area 105 is close to the feeding device 2, the right work area 104 is away from the feeding device 2 relative to the left work area 105 and close to the discharging device 3, the left dispensing mechanism 102 performs dispensing work on the workpiece conveyed to the left work area 105, the right dispensing mechanism 101 performs dispensing work on the workpiece conveyed to the right work area 104, based on the workpiece conveying direction, the workpiece to be processed is preferentially conveyed to the right work area 104, and then another workpiece to be processed is conveyed to the left work area 105, so that the dispensing device 1 is designed as four tracks and eight stations, the work conveying mechanism 103 is a structure for driving the carrier disc to move along the x-axis direction, the carrier disc carries at least one workpiece, the work conveying mechanism 103 can be a belt conveying structure, the belt conveying structure preferably adopts a group of belt structures, compared with the right work area 104 corresponding to the right belt structure, the left work area 105 corresponding to the left belt structure, this design of two groups of belt structures makes the structure more complex and increases the cost;

[0065] The feeding device 2 is used for conveying the workpiece to be processed to any work conveying mechanism 103, and conveying two workpieces to be processed to the same work conveying mechanism 103 in sequence;

[0066] The left dispensing mechanism 102 is used for sequentially performing dispensing work on a plurality of workpieces conveyed to a plurality of left work areas 105, and the workpiece in each left work area 105 is subjected to dispensing work at least twice;

[0067] The right dispensing mechanism 101 is used for sequentially performing dispensing work on a plurality of workpieces conveyed to a plurality of right work areas 104, and the workpiece in each right work area 104 is subjected to dispensing work at least twice;

[0068] The discharging device 3 is used for receiving two workpieces on any work conveying mechanism 103 which have completed dispensing work, and preferentially receiving the workpiece on the right work area 104 and then receiving the workpiece on the left work area 105.

[0069] Taking the right dispensing mechanism 101 as an example, for example, the right work area 104 of each of the four work conveying mechanisms 103 is provided with a carrier disc carrying workpieces, and each carrier disc carries three workpieces. The right dispensing mechanism 101 moves to the right work area 104 of the first work conveying mechanism 103, and sequentially performs the first dispensing operation on the three workpieces carried on the carrier disc of the right work area 104, and then waits for the second dispensing operation on the three workpieces on the carrier disc. At this time, the right dispensing mechanism 101 moves to the right work area 104 of the second work conveying mechanism 103, and sequentially performs the dispensing operation on the three workpieces carried on the carrier disc of the right work area 104. After sequentially performing the dispensing operation on the three workpieces carried on the carrier disc of the right work area 104 of the third work conveying mechanism 103 and the fourth work conveying mechanism 103 in turn, the execution end of the right dispensing mechanism 101 returns to the right work area 104 of the first work conveying mechanism 103. At this time, the glue of the first workpiece on the carrier disc of the right work area 104 has filled the gap between the chip and the substrate, and is ready for the second dispensing operation. The right dispensing mechanism 101 repeats the above operation in a cycle until the multiple dispensing operations on all workpieces on all right work areas 104 are completed.

[0070] Therefore, when the dispensing mechanism completes a dispensing operation and is in an idle period waiting for the next operation, it does not idle and wait, but moves to the corresponding work area of the other work conveying mechanism 103 to continue the dispensing operation. The dispensing mechanism can process more workpieces by using the glue bottom filling delay time, avoid idle waiting time of the equipment, improve the overall production efficiency, and the left dispensing mechanism 102 and the right dispensing mechanism 101 can operate according to this mode, increase the number of dispensing operations of a single machine, and improve the production efficiency of the bottom filling process of large chip products. The dispensing equipment 1 of one dispensing machine adopts the design of multiple work conveying mechanisms 103 cooperating with the right dispensing mechanism 101 and the left dispensing mechanism 102, which solves the problem of increasing the machine area and increasing the cost caused by increasing the number of dispensing machines to improve the production efficiency in the traditional scheme.

[0071] Specifically, the dispensing operation number of the workpiece on each work conveying mechanism 103 is at least twice. For large-particle FCBGA chip products, the dispensing operation number of the workpiece on each work conveying mechanism 103 is about 6-8 times. The optimal execution process of the right dispensing mechanism 101 or the left dispensing mechanism 102 is as follows: after performing a dispensing operation on the work area of the first work conveying mechanism 103 and sequentially on the work area of the last work conveying mechanism 103, the glue on the workpiece in the work area of the first work conveying mechanism 103 is just filled in the gap between the chip and the substrate. At this time, the right dispensing mechanism 101 or the left dispensing mechanism 102 returns to the first work conveying mechanism 103 again to perform the next dispensing operation on the workpiece in the work area of the work conveying mechanism 103. The process is repeated until all dispensing operations on the workpiece in all work conveying mechanisms 103 are completed. This avoids idle waiting time of the equipment, maximizes the interval time between two dispensing operations of the workpiece, and improves the overall production efficiency.

[0072] In a preferred embodiment, the right dispensing mechanism 101 and the left dispensing mechanism 102 can not only perform dispensing operations on the workpiece in each work conveying mechanism 103, but also perform mounting operations.

[0073] In a preferred embodiment, the dispensing equipment 1 further comprises a plurality of preheating mechanisms 106 and a plurality of heat preservation mechanisms 107. The number of the plurality of preheating mechanisms 106, the plurality of heat preservation mechanisms 107 and the plurality of work conveying mechanisms 103 is adapted, and one work conveying mechanism 103 corresponds to one preheating mechanism 106 and one heat preservation mechanism 107. The preheating mechanism 106 is located between the feeding equipment 2 and the work conveying mechanism 103, and receives two workpieces to be processed output by the feeding equipment 2 in sequence. The preheating mechanism 106 is used to preheat the two workpieces to be processed moving to the preheating mechanism 106. After the preheating of the two workpieces to be processed is completed, one of the two workpieces to be processed is preferentially conveyed to the right work area 104 of the work conveying mechanism 103 corresponding to the workpiece, and the other workpiece to be processed is conveyed to the left work area 105 of the work conveying mechanism 103 corresponding to the workpiece. The heat preservation mechanism 107 is located between the work conveying mechanism 103 and the discharging equipment 3. The heat preservation mechanism 107 is used to heat preserve the two workpieces moving to the heat preservation mechanism 107 after the dispensing operation is completed. The workpiece in the right work area 104 is preferentially conveyed to the heat preservation mechanism 107, and the workpiece in the left work area 105 is conveyed to the heat preservation mechanism 107 after passing through the right work area 104. The heat preservation mechanism 107 sequentially pushes the two workpieces completing the dispensing to the discharging equipment 3.

[0074] In a preferred embodiment, the preheating mechanism 106 comprises an upper preheating station 106-1 and a lower preheating station 106-2 which are movable up and down and are stacked in the up-down direction, two workpieces to be processed are respectively conveyed to the upper preheating station 106-1 and the lower preheating station 106-2, one of the upper preheating station 106-1 and the lower preheating station 106-2 preferentially conveys the preheated workpiece to the right work area 104, and the other preheating station conveys the preheated workpiece to the left work area 105 after moving in the up-down direction. The upper preheating station 106-1 and the lower preheating station 106-2 can be stacked on a preheating mounting platform 106-3, the preheating mounting platform 106-3 is mounted on the moving end of a preheating jacking mechanism 106-4, the preheating jacking mechanism 106-4 refers to a component that can drive the body to move in a straight line direction, the preheating jacking mechanism 106-4 can be a driving cylinder, a hydraulic cylinder or an electric push rod, etc., the preheating jacking mechanism 106-4 drives the upper preheating station 106-1 and the lower preheating station 106-2 to move as a whole in the z-axis direction to dock with the feeding device 2 or the work conveying mechanism 103, thereby realizing the feeding, preheating and discharging of the two workpieces to be processed. Referring to Figure 19 As shown in the figure, the upper preheating station 106-1 and the lower preheating station 106-2 both have a conveying belt 106-5 for conveying workpieces and a heating lifting module 106-6, the conveying belt 106-5 is used to convey the workpieces in the x-axis direction, here the conveying belt 106-5 refers to two conveying belts which are spaced apart in the x-axis direction, the heating lifting module 106-6 is arranged between the two conveying belts and below the conveying belts, the heating lifting module 106-6 refers to that when the workpiece is conveyed by the conveying belt 106-5 to the preheating station, the lifting end of the heating lifting module 106-6 rises in the z-axis direction, when it rises to contact the workpiece, it continues to lift, so that the lifted workpiece is separated from the conveying belt 106-5 in an up-down manner, at this time, the lifted workpiece is closely attached to the surface of the lifting end of the heating lifting module 106-6, then the heating lifting module 106-6 preheats the workpiece, after the preheating is completed, the lifting end of the heating lifting module 106-6 lowers together with the workpiece, so that the workpiece is placed on the conveying belt 106-5 again. Thus, the upper preheating station 106-1 and the lower preheating station 106-2 are stacked in the up-down direction, reducing the stretching range of the equipment in the horizontal direction, and the upper preheating station 106-1 and the lower preheating station 106-2 which are movable up and down are docked with the work conveying mechanism 103, so that the preheated workpieces can be conveyed to the corresponding work areas of the work conveying mechanism 103 for subsequent dispensing work.

[0075] Specifically, the upper and lower preheating stations can simultaneously or alternately preheat the workpieces. Specifically, the simultaneous operation process is as follows: after the upper and lower preheating stations simultaneously complete the preheating of the workpieces, one of the preheating stations first delivers the preheated workpiece to the right operation area 104, and the other preheating station delivers the preheated workpiece to the left operation area 105 after moving in the up-down direction. The alternating operation process is as follows: while one preheating station completes preheating and during the time of lifting and delivering the workpiece to the corresponding operation area, the other preheating station simultaneously preheats the workpiece placed thereon. When the previous workpiece completely leaves the preheating station, the other preheating station also completes preheating and lifts to deliver the workpiece to the corresponding operation area, thereby reducing the waiting time of the workpiece in the preheating link, speeding up the workpiece into the subsequent dispensing operation, and ensuring that the upper and lower preheating stations 106-2 can work cooperatively to ensure that preheated workpieces are always ready to enter the dispensing operation of the operation conveying mechanism 103, realizing the continuity of production and improving the overall production efficiency.

[0076] In a preferred embodiment, the heat preservation mechanism 107 includes an upper heat preservation station 107-1 and a lower heat preservation station 107-2 that can move up and down. The upper heat preservation station 107-1 and the lower heat preservation station 107-2 are stacked in the up-down direction. One of the upper heat preservation station 107-1 and the lower heat preservation station 107-2 is used to preferentially receive the workpiece that has completed the dispensing operation on the right operation area 104, and the other heat preservation station moves in the up-down direction to receive the workpiece that has completed the dispensing operation on the left operation area 105. Both the upper heat preservation station 107-1 and the lower heat preservation station 107-2 are used for heat preservation of the workpiece. The upper heat preservation station 107-1 and the lower heat preservation station 107-2 can be stacked on a heat preservation mounting platform 107-3, which is mounted on the moving end of a heat preservation lifting mechanism 107-4. The heat preservation lifting mechanism 107-4 refers to a component that can drive the body to move in a straight line direction. The heat preservation lifting mechanism 107-4 can be a driving cylinder, a hydraulic cylinder, or an electric push rod, etc. The heat preservation lifting mechanism 107-4 drives the upper heat preservation station 107-1 and the lower heat preservation station 107-2 to move in the z-axis direction as a whole to dock with the operation conveying mechanism 103 or the feeding device 3, thereby realizing the feeding, heat preservation, and feeding of two workpieces to be processed. The upper heat preservation station 107-1 and the lower heat preservation station 107-2 also each have a conveying belt 106-5 and a heating lifting module 106-6 for conveying the workpiece. Thus, the upper heat preservation station 107-1 and the lower heat preservation station 107-2 are stacked in the up-down direction, reducing the stretching range of the equipment in the horizontal direction, and the upper heat preservation station 107-1 and the lower heat preservation station 107-2 are docked with the operation conveying mechanism 103 through the up-down movement, so that the workpieces after dispensing on the right and left operation areas 105 can be delivered to the corresponding heat preservation stations for subsequent heat preservation, realizing the heat preservation operation of two workpieces.

[0077] Specifically, the upper and lower heat preservation stations can simultaneously or alternately perform heat preservation treatment on the workpieces. In the simultaneous operation process, one heat preservation station is used to receive the workpieces after the glue dispensing operation in the right operation area 104, and the other heat preservation station receives the workpieces after the glue dispensing operation in the left operation area 105 after moving in the up-down direction, and then the two heat preservation stations simultaneously perform heat preservation treatment. In the alternate operation process, one heat preservation station receives the workpieces after the glue dispensing operation in the corresponding operation area and starts to perform heat preservation treatment. During the heat preservation time, the other heat preservation station moves up and down to receive the workpieces after the glue dispensing operation in the corresponding operation area and starts to perform heat preservation treatment. During the heat preservation treatment of the other heat preservation station, the previous heat preservation station ends the heat preservation treatment and can transport the workpieces after the heat preservation treatment to the next process, and the above process is repeated, thereby reducing the waiting time of the workpieces in the heat preservation link, speeding up the workpieces entering the subsequent detection operation, and ensuring the continuity of production and improving the overall production efficiency.

[0078] In a preferred embodiment, the right and left lifting mechanisms 108 and 109 are arranged below each operation conveying mechanism 103. The right lifting mechanism 108 is arranged in the right operation area 104 and lifts the workpiece moving to the right operation area 104 along the z-axis direction to separate the workpiece from the operation conveying mechanism 103. The left lifting mechanism 109 is arranged in the left operation area 105 and lifts the workpiece moving to the left operation area 105 along the z-axis direction to separate the workpiece from the operation conveying mechanism 103. The right and left lifting mechanisms 108 and 109 are components that can drive the movement of the body in a straight line direction. The right and left lifting mechanisms 108 and 109 can be driving cylinders, hydraulic cylinders, or electric push rods, etc. Thus, each operation area can lift and position the workpiece moving to the operation area through the corresponding lifting mechanism, which can ensure that the workpiece is in a stable and accurate position during the glue dispensing process, avoid the deviation of the glue dispensing position caused by the shaking and displacement of the workpiece, and greatly improve the accuracy of the glue dispensing. The lifting mechanism is used to lift the workpiece to separate the workpiece from the operation conveying mechanism 103, which has the advantages of simple structure and easy implementation compared with the method of moving the operation conveying mechanism 103 along the z-axis direction to achieve this separation state. If the operation conveying mechanism 103 moves up and down, the structure will be more complex and the cost will be increased.

[0079] In a preferred embodiment, the dispensing device 1 further comprises a first x-axis guide rail mechanism 110, a second x-axis guide rail mechanism 111, a first y-axis guide rail mechanism 112 and a second y-axis guide rail mechanism 113. The first x-axis guide rail mechanism 110 and the second x-axis guide rail mechanism 111 are both arranged along the x-axis direction and are respectively installed on both sides of the work conveying mechanism 103. The first y-axis guide rail mechanism 112 is arranged on the first x-axis guide rail mechanism 110 and the second x-axis guide rail mechanism 111 and is located on the left side of the work conveying mechanism 103 corresponding to the left work area 105. The left dispensing mechanism 102 is connected to the first y-axis guide rail mechanism 112 and performs dispensing work on the workpiece in the left work area 105. The second y-axis guide rail mechanism 113 is arranged on the first x-axis guide rail mechanism 110 and the second x-axis guide rail mechanism 111 and is located on the right side of the work conveying mechanism 103 corresponding to the right work area 104. The right dispensing mechanism 101 is connected to the second y-axis guide rail mechanism 113 and performs dispensing work on the workpiece in the right work area 104. Thus, due to the plurality of parallel work conveying mechanisms 103, the first x-axis guide rail mechanism 110 and the second x-axis guide rail mechanism 111 are respectively arranged on the outer sides of the first and last work conveying mechanisms 103. In combination with the first y-axis guide rail mechanism 112 and the second y-axis guide rail mechanism 113, a large-span movement track is provided for the left dispensing mechanism 102 and the right dispensing mechanism 101. The double guide rail mechanisms can provide stable support to ensure that the left dispensing mechanism 102 and the right dispensing mechanism 101 can be accurately positioned in the x-axis and y-axis directions, thereby ensuring dispensing accuracy. The left dispensing mechanism 102 and the right dispensing mechanism 101 can be independently driven to move on the guide rail mechanisms, realizing double-drive parallel operation. The two dispensing mechanisms can simultaneously perform dispensing operations on workpieces in different work areas, greatly shortening the production cycle and improving production efficiency.

[0080] Specifically, the first x-axis guide rail mechanism 110 is provided with a first driving motor and a second driving motor. The second driving motor is used to drive the right dispensing mechanism 101 to move along the x-axis direction to perform dispensing work on the workpiece in the right work area 104. The first driving motor is used to drive the left dispensing mechanism 102 to move along the x-axis direction to perform dispensing work on the workpiece in the left work area 105.

[0081] Preferably, the first driving motor and the second driving motor can adopt a linear motor. The reason for using a linear motor is that the linear motor has high speed and large thrust, further improving work efficiency.

[0082] The first driving motor, the second driving motor, the first x-axis guide rail mechanism 110, the second x-axis guide rail mechanism 111, the first y-axis guide rail mechanism 112 and the second y-axis guide rail mechanism 113 constitute a rigid double-drive gantry, which has high machining precision, large load capacity and fast response speed. The first y-axis guide rail mechanism 112 is driven by the first driving motor, thereby ensuring the dispensing precision of the left dispensing mechanism 102. Compared with the case where one driving motor is respectively installed on the first x-axis guide rail mechanism 110 and the second x-axis guide rail mechanism 111 to jointly drive the first y-axis guide rail mechanism 112 to move, the driving mode of two motors is prone to cause the first y-axis guide rail mechanism 112 to tilt due to the speed error of the two motors, thereby affecting the dispensing precision of the right dispensing mechanism 101.

[0083] In a preferred embodiment, the first y-axis guide rail mechanism 112 is provided with a first z-axis guide rail mechanism 114, the second y-axis guide rail mechanism 113 is provided with a second z-axis guide rail mechanism 115, the left dispensing mechanism 102 is connected with the first z-axis guide rail mechanism 114, and the right dispensing mechanism 101 is connected with the second z-axis guide rail mechanism 115. The first x-axis guide rail mechanism 110, the second x-axis guide rail mechanism 111, the first y-axis guide rail mechanism 112 and the first z-axis guide rail mechanism 114 constitute a three-axis motion mechanism, which is used to drive the left dispensing mechanism 102 to move along the xyz direction, so as to perform dispensing work on the workpiece on the left work area 105. The first x-axis guide rail mechanism 110, the second x-axis guide rail mechanism 111, the second y-axis guide rail mechanism 113 and the second z-axis guide rail mechanism 115 constitute a three-axis motion mechanism, which is used to drive the right dispensing mechanism 101 to move along the xyz direction, so as to perform dispensing work on the workpiece on the right work area 104.

[0084] Specifically, the first x-axis guide rail mechanism 110, the second x-axis guide rail mechanism 111, the first y-axis guide rail mechanism 112, the second y-axis guide rail mechanism 113, the first z-axis guide rail mechanism 114 and the second z-axis guide rail mechanism 115 refer to track structures with a certain length, and a conveying unit for pushing the product to slide along the length direction of the track structure is further arranged on the track structure. The conveying unit can be a slide rail and slide block structure.

The feeding storage platform 201 is used to store workpieces to be processed. The feeding jacking mechanism 202 is used to drive the feeding storage platform 201 to ascend and descend along the z-axis direction. The feeding clamping mechanism 204 is installed on the feeding connection conveying mechanism 203 and is used to take out the workpieces to be processed from the feeding storage platform 201. The feeding connection conveying mechanism 203 is arranged between the feeding storage platform 201 and the dispensing device 1 and is used to convey the workpieces to be processed to any preheating mechanism 106. In this way, the feeding jacking mechanism 202 is used to make the feeding storage platform 201 ascend and descend only along the z-axis direction, and the feeding connection conveying mechanism 203 which can move along the y-axis direction is used to distribute the workpieces to be processed on the feeding storage platform 201 to each preheating mechanism 106, so that the feeding storage platform 201 can store more workpieces, and the overall machine size is more compact. Compared with the conventional feeding storage platform 201 which ascends along the z-axis and moves along the y-axis to distribute and connect, in the case of a fixed overall machine size, the conventional feeding storage platform 201 which moves along the y-axis to distribute and connect will be limited in connection stroke as the number of work conveying mechanisms 103 increases, and may not be able to meet the connection needs of all work conveying mechanisms 103.

[0087] Specifically, the feeding storage platform 201 refers to a plate-shaped component with a certain area, which can place a plurality of feeding boxes 205, and the feeding boxes 205 contain workpieces to be processed. The feeding jacking mechanism 202 refers to a component that can drive a body to move along a straight line. The feeding jacking mechanism 202 can be a driving cylinder, a hydraulic cylinder or an electric push rod, etc. Preferably, as shown in the Figure 11 The feeding jacking mechanism 202 comprises a driving motor, a lead screw and a nut mounting seat. The lead screw is directly connected to the motor shaft of the driving motor, and extends along the z-axis direction. The nut mounting seat is sleeved on the lead screw, and the feeding storage platform 201 is mounted on the nut mounting seat.

[0088] The feeding connection conveying mechanism 203 comprises a feeding y-axis linear module 203-1 and a feeding conveying device 203-2. The feeding y-axis linear module 203-1 is used to drive the feeding conveying device 203-2 to move along the y-axis direction to connect the feeding storage platform 201 and each preheating mechanism 106. The feeding conveying device 203-2 is used to convey the workpieces to be processed to any preheating mechanism 106. The feeding conveying device 203-2 refers to a conveying structure for conveying products. Specifically, the feeding conveying device 203-2 can be a conveyor belt structure.

[0089] The upper feeding and clamping mechanism 204 is installed on the upper feeding conveying device 203-2, and the upper feeding and clamping mechanism 204 comprises an upper feeding and clamping jaw assembly 204-1 and a clamping jaw driving structure 204-2. The upper feeding and clamping jaw assembly 204-1 is arranged at the driving end of the clamping jaw driving structure 204-2. The clamping jaw assembly is used for clamping the workpiece. The clamping jaw driving structure 204-2 is used for driving the clamping jaw assembly to move so as to drive the workpiece to move together to the upper feeding conveying device 203-2 when the clamping jaw assembly clamps the workpiece. The upper feeding conveying device 203-2 is used for conveying the product to each preheating mechanism 106. Specifically, the upper feeding and clamping mechanism 204 is provided in two groups, and the two groups of upper feeding and clamping mechanisms 204 are arranged on the two sides of the workpiece respectively. This design is because the large-particle FCBGA chip product is large in size and heavy in weight. The two groups of upper feeding and clamping mechanisms 204 clamp the two sides of the workpiece and pull the workpiece, so as to prevent the workpiece from deviating. Specifically, the clamping jaw assembly refers to a component that can clamp an article. The clamping jaw assembly can be a clamping jaw cylinder, a hydraulic clamping jaw or the like. The clamping jaw driving structure 204-2 is used for driving the clamping jaw assembly to move along the x-axis and the z-axis directions. When working, the clamping jaw driving structure 204-2 can drive the clamping jaw assembly to move along the x-axis to approach one workpiece in the upper feeding and storing platform 201 and clamp the workpiece. After clamping the workpiece, the clamping jaw driving structure 204-2 drags the workpiece to the upper feeding conveying device 203-2 along the x-axis. Then, the clamping jaw assembly is opened. The clamping jaw driving structure 204-2 continues to retreat to the outside of the workpiece along the x-axis. The clamping jaw assembly is closed. The clamping jaw driving structure 204-2 drives the clamping jaw assembly to descend along the z-axis, so as to prevent interference with the workpiece conveying. Finally, the upper feeding conveying device 203-2 and the upper feeding y-axis linear module 203-1 are used for conveying the workpiece to each preheating mechanism 106. Through the cooperation of the clamping jaw assembly, the clamping jaw driving structure 204-2 and the upper feeding conveying device 203-2, the product can be conveniently conveyed.

[0090] In a preferred embodiment, the unloading device 3 comprises an unloading storage platform 301, an unloading jacking mechanism 302, an unloading connecting conveying mechanism 303 and an AOI detection mechanism 304. The unloading storage platform 301 is used to store the detected workpieces. The unloading jacking mechanism 302 is used to drive the unloading storage platform 301 to ascend and descend along the z-axis direction. The AOI detection mechanism 304 is arranged on one side of the unloading connecting conveying mechanism 303 and is used to detect the machined workpieces. The unloading connecting conveying mechanism 303 is arranged between the dispensing device 1 and the unloading storage platform 301 and is used to receive the machined workpieces on any heat preservation mechanism 107. The unloading connecting conveying mechanism 303 conveys the machined workpieces to the AOI detection mechanism 304 below for detection and conveys the detected workpieces to the unloading storage platform 301. Thus, the unloading jacking mechanism 302 makes the unloading storage platform 301 ascend and descend only along the z-axis direction, and the unloading connecting conveying mechanism 303 which can move along the y-axis direction can receive the machined workpieces on each heat preservation mechanism 107 and convey the machined workpieces to the AOI detection mechanism 304 below for detection and convey the detected workpieces to the unloading storage platform 301, so that the unloading storage platform 301 can store more workpieces and the overall machine size is more compact. Compared with the traditional unloading storage platform 301 which ascends along the z-axis and moves along the y-axis to receive and store workpieces, in the case of a fixed overall machine size, the traditional unloading storage platform 301 which moves along the y-axis to receive and store workpieces will have its receiving stroke limited with the increase of the number of work conveying mechanisms 103, which may not meet the receiving requirements of all work conveying mechanisms 103.

[0091] Specifically, the unloading storage platform 301 refers to a plate-shaped component with a certain area, which can place a plurality of unloading boxes 305, and the unloading boxes 305 contain machined and detected workpieces. The unloading jacking mechanism 302 refers to a component that can drive a body to move along a straight line. The unloading jacking mechanism 302 can be a driving cylinder, a hydraulic cylinder, a motor screw mechanism or an electric push rod, etc.

The feeding conveying device 303-2 is installed on the moving end of the feeding y-axis linear module 303-1. The feeding y-axis linear module 303-1 is used to drive the feeding conveying device 303-2 to move along the y-axis direction to connect the various heat preservation mechanisms 107, the AOI detection mechanism 304 and the feeding storage platform 301. The feeding conveying device 303-2 refers to a conveying structure used for conveying products. Specifically, the feeding conveying device 303-2 can be a conveyor belt structure. The feeding push rod device 303-3 is installed on the feeding conveying device 303-2. The feeding push rod device 303-3 comprises a lifting slide 303-3-1 which can move along the z-axis direction and a push rod assembly 303-3-2 installed on the lifting slide 303-3-1. The push rod assembly 303-3-2 has a push rod which can move along the x-axis direction. When the work is performed, after the AOI detection mechanism 304 finishes detection, the feeding conveying device 303-2 is close to the feeding storage platform 301. After the feeding conveying device 303-2 at least conveys a part of the workpiece to the upper surface of the feeding storage platform 301, the lifting slide 303-3-1 is lifted. Finally, the push rod pushes the workpiece to the feeding box 305 of the feeding storage platform 301 along the x-axis direction. Through the cooperation of the feeding push rod device 303-3 and the feeding conveying device 303-2, the feeding and conveying of the products can be more convenient.

[0093] Specifically, the AOI detection mechanism 304 comprises a three-axis moving module 304-1 and a visual detection module 304-2. The three-axis moving module 304-1 is arranged on one side of the feeding connection and conveying mechanism 303. The three-axis moving module 304-1 is used to drive the visual detection module 304-2 to move along the xyz direction. The visual detection module 304-2 is used to detect the workpiece which has been glued and solidified on the feeding connection and conveying mechanism 303.

[0094] The dispensing operation method of the present application is as follows:

[0095] Step S1, stack the workpieces on the feeding storage platform 201.

[0096] Step S2, the feeding connection and conveying mechanism 203 is close to the feeding storage platform 201. The feeding lifting mechanism 202 drives the feeding storage platform 201 to move along the z-axis direction, so that the uppermost workpiece of the feeding storage platform 201 is in the flush position with the feeding connection and conveying mechanism 203.

[0097] Step S3, the gripper driving structure 204-2 drives the gripper assembly to approach the uppermost workpiece in the feeding storage platform 201 and clamps the workpiece, after clamping the workpiece, the gripper driving structure 204-2 drags the workpiece to the feeding conveying device 203-2, then the gripper assembly is opened, the gripper driving structure 204-2 retreats to the outside of the workpiece, and the gripper driving structure 204-2 drives the gripper assembly to descend;

[0098] Step S4, the feeding connection conveying mechanism 203 drives the workpiece to move to any preheating mechanism 106, any preheating station of the upper preheating station 106-1 and the lower preheating station 106-2 is lifted to be flush with the feeding connection conveying mechanism 203, the feeding connection conveying mechanism 203 conveys the workpiece to the preheating station, and the preheating station preheats the workpiece;

[0099] Step S5, repeat the above steps S2-S4 until the conveying of the workpieces on the eight preheating stations is completed;

[0100] Step S6, after the preheating of the workpiece in each preheating mechanism 106 is completed, one of the preheating stations conveys the preheated workpiece to the right work area 104 first, and the other preheating station moves along the up-down direction and then conveys the preheated workpiece to the left work area 105;

[0101] Step S7, the right lifting mechanism 108 lifts the workpiece moved to the right work area 104 along the z-axis direction, so that the lifted workpiece is in an up-down separated state with the work conveying mechanism 103, and the left lifting mechanism 109 lifts the workpiece moved to the left work area 105 along the z-axis direction, so that the lifted workpiece is in an up-down separated state with the work conveying mechanism 103;

[0102] Step S8, the right dispensing mechanism 101 moves to one of the right work areas 104 of the work conveying mechanism 103 through the three-axis motion mechanism, and sequentially performs a dispensing operation on the multiple workpieces conveyed to the right work area 104, and when the waiting time for executing the next dispensing operation is reached, the right dispensing mechanism 101 moves to another right work area 104 of the work conveying mechanism 103 through the three-axis motion mechanism, and sequentially performs a dispensing operation on the multiple workpieces in the right work area 104, and the cycle is repeated until all dispensing operations on all workpieces in all right work areas 104 are completed;

[0103] The left dispensing mechanism 102 moves to one of the left work areas 105 of the work conveying mechanism 103 through the three-axis motion mechanism, and when the dispensing mechanism 102 completes the dispensing operation on the workpieces in the left work area 105 and waits for the next dispensing operation, the left dispensing mechanism 102 moves to another left work area 105 of the work conveying mechanism 103 through the three-axis motion mechanism, and performs the dispensing operation on the workpieces in the left work area 105, and the dispensing operation is repeated until all the workpieces in the left work area 105 are dispensed.

[0104] Step S9, after the dispensing of the workpiece is completed, the right lifting mechanism 108 and / or the left lifting mechanism 109 drives the workpiece to descend and place it on the work conveying mechanism 103.

[0105] Step S10, the work conveying mechanism 103 preferentially conveys the workpiece on which the dispensing operation has been completed in the right work area 104 to one heat preservation station, and another heat preservation station moves in the up-down direction to receive the workpiece on which the dispensing operation has been completed in the left work area 105, and then the two heat preservation stations can perform heat preservation treatment on the workpiece respectively or simultaneously.

[0106] Step S11, after the heat preservation treatment is completed, the unloading connection conveying mechanism 303 moves to the heat preservation mechanism 107, and any one of the upper heat preservation station 107-1 and the lower heat preservation station 107-2 is lifted to be flush with the unloading connection conveying mechanism 303, and the heat preservation station conveys the workpiece after heat preservation to the unloading connection conveying mechanism 303.
