Description

Technical Field

[0001] The present invention relates to the technical field of glue dispensing, and in particular to multi-track glue dispensing operation equipment and a glue dispensing operation method thereof. Background Art

[0002] Underfill dispensing is a common back-end packaging and testing process in semiconductor manufacturing. Traditional dispensing machines dispense glue onto the product on a carrier. Once the glue on the product has fully filled the gap between the chip and the substrate, another round of dispensing begins. This cycle repeats, completing multiple dispensing operations.

[0003] In traditional processes, due to the small size of chips, 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. In addition, due to the large size of the chips, after completing a dispensing operation, the time required for the glue to flow and fill the gap between the chip and the substrate is also significantly extended. More importantly, most of the existing dispensing machines use a single-track operation mode. When the chip on the track completes a dispensing operation, the dispensing execution module can only wait because the glue has not yet fully filled the gap, which undoubtedly wastes time. Therefore, with the continuous increase in the size of high-performance chip packages and the long delay in bottom filling, the production capacity of a dispensing machine has dropped significantly. If you want to improve production efficiency, you need to add more dispensing machines, but adding more dispensing machines will increase the floor space occupied by the machine and increase costs, which poses a challenge to the spatial layout of the current production workshop. Summary of the Invention

[0004] The technical problems solved by the present invention are: low production efficiency, large machine footprint and high cost.

[0005] To this end, the present invention provides a multi-track dispensing operation device and a dispensing operation method thereof, which improves the production efficiency of the underfill process of large chip products and reduces the floor space occupied by a single machine.

[0006] The multi-track dispensing operation equipment according to an embodiment of the present invention includes: a loading device, a dispensing device and a unloading device arranged in sequence along the workpiece conveying direction; The dispensing device includes a left dispensing mechanism, a right dispensing mechanism and a plurality of operation conveying mechanisms, wherein the plurality of operation conveying mechanisms are arranged in parallel, and the left dispensing mechanism and the right dispensing mechanism are arranged opposite to each other and straddle the plurality of operation conveying mechanisms, and the straddle direction is perpendicular to the workpiece conveying direction; Each of the work conveying mechanisms is provided with a left working area and a right working area along the workpiece conveying direction, the left working area being close to the loading device, and the right working area being relatively far away from the loading device and close to the unloading device. The left gluing mechanism performs gluing on the workpiece conveyed to the left working area, and the right gluing mechanism performs gluing on the workpiece conveyed to the right working area. Based on the workpiece conveying direction, the workpiece to be processed is preferentially conveyed to the right working area, and then the other workpiece to be processed is conveyed to the left working area. The loading device is used to transport the workpiece to be processed to any one of the operation conveying mechanisms, and to sequentially transport two workpieces to be processed to the same operation conveying mechanism; The left glue dispensing mechanism is used to sequentially perform glue dispensing operations on multiple workpieces conveyed to multiple left working areas; The right glue dispensing mechanism is used to sequentially perform glue dispensing operations on multiple workpieces conveyed to multiple right working areas; The unloading equipment is used to take over two workpieces that have completed the dispensing operation on any one of the operation conveying mechanisms, and gives priority to taking over the workpieces on the right operation area, and then takes over the workpieces on the left operation area.

[0007] The beneficial effect of the present invention is that by setting up multiple parallel operation conveying mechanisms, each operation conveying mechanism is provided with a left operation area and a right operation area, and the dispensing operation area of ​​the single-machine dispensing equipment is correspondingly increased. The two dispensing mechanisms are independent of each other. The left dispensing mechanism performs dispensing operations on multiple workpieces in the left operation area, and the right dispensing mechanism performs dispensing operations on multiple workpieces in the right operation area. Each dispensing mechanism can make full use of the time required for the glue to fill the gap in the current operation area to perform dispensing operations in other operation areas, thereby avoiding idle waiting time of the equipment and improving production efficiency.

[0008] According to one embodiment of the present invention, the right dispensing mechanism is moved to the right operating area of ​​one of the work conveying mechanisms via a three-axis motion mechanism, and after sequentially performing a dispensing operation on multiple workpieces conveyed to the right operating area and in a waiting time for performing the next dispensing operation, the right dispensing mechanism can be moved to the right operating area of ​​another of the work conveying mechanisms via the three-axis motion mechanism, and sequentially perform dispensing operations on multiple workpieces on the other right operating area; The left dispensing mechanism is moved to the left operating area of ​​one of the operation conveying mechanisms through the three-axis motion mechanism, and after performing a dispensing operation on multiple workpieces conveyed to the left operating area in sequence and in the waiting time for the next dispensing operation, the left dispensing mechanism can be moved to the left operating area of ​​another operation conveying mechanism through the three-axis motion mechanism, and perform dispensing operations on multiple workpieces on the other left operating area in sequence. Therefore, during the idle period when the dispensing mechanism completes a dispensing operation and is waiting to perform the next operation, it does not idle and wait, but moves to the corresponding operating area of ​​other operation conveying mechanisms to continue to perform the dispensing operation. The delay time for filling the bottom of the glue liquid is used to enable the dispensing mechanism to process more workpieces, avoid idle waiting time for the equipment, and improve overall production efficiency. Both the left dispensing mechanism and the right dispensing mechanism 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.

[0009] According to one embodiment of the present invention, the dispensing equipment further includes a plurality of preheating mechanisms and a plurality of heat-insulating mechanisms, the number of the plurality of preheating mechanisms, the plurality of heat-insulating mechanisms and the plurality of operation conveying mechanisms are adapted, and one operation conveying mechanism corresponds to one preheating mechanism and one heat-insulating mechanism; The preheating mechanism is located between the loading device and the operation conveying mechanism, and receives two workpieces to be processed sequentially output by the loading device. The preheating mechanism is used to preheat the two workpieces to be processed moved onto the preheating mechanism. After the two workpieces to be processed are preheated, one of the workpieces to be processed is preferentially conveyed to the right operation area of ​​the operation conveying mechanism corresponding thereto, and then the other workpiece to be processed is conveyed to the left operation area of ​​the operation conveying mechanism corresponding thereto. The insulation mechanism is located between the operation conveying mechanism and the unloading equipment. The insulation mechanism insulates the two workpieces that have completed the dispensing operation and are moved onto the insulation mechanism. Among them, the workpieces in the right operation area are first conveyed to the insulation mechanism, and the workpieces in the left operation area are conveyed to the insulation mechanism after passing through the right operation area. The insulation mechanism pushes the two workpieces that have completed dispensing to the unloading equipment in turn.

[0010] According to one embodiment of the present invention, the preheating mechanism includes an upper preheating station and a lower preheating station that can move up and down. The upper preheating station and the lower preheating station are stacked in the vertical direction. Two workpieces to be processed are transported to the upper preheating station and the lower preheating station respectively. One of the upper preheating station and the lower preheating station preferentially transports the preheated workpiece to the right working area, and the other preheating station moves in the vertical direction and transports the preheated workpiece to the left working area. As a result, the upper preheating station and the lower preheating station are stacked in the vertical direction, reducing the horizontal extension range of the equipment. The upper preheating station and the lower preheating station that can move up and down are used to connect to the work conveying mechanism, and the two preheated workpieces are sequentially transported to the corresponding working areas on the work conveying mechanism for subsequent dispensing operations. One preheating mechanism can achieve the preheating operation of two workpieces, improving work efficiency and not occupying horizontal area.

[0011] According to one embodiment of the present invention, the insulation mechanism includes an upper insulation station and a lower insulation station that can be moved up and down, and the upper insulation station and the lower insulation station are stacked in the vertical direction. One of the upper insulation station and the lower insulation station is used to preferentially take over the workpiece that has completed the dispensing operation in the right working area, and the other insulation station moves in the vertical direction to take over the workpiece that has completed the dispensing operation in the left working area. The upper insulation station and the lower insulation station are both used to insulate the workpiece. Thus, the upper insulation station and the lower insulation station are stacked in the vertical direction, reducing the horizontal extension range of the equipment, and the upper insulation station and the lower insulation station that can be moved up and down are used to connect the operation conveying mechanism, so that the workpieces after dispensing in the right and left working areas can be sequentially conveyed to the corresponding insulation station for subsequent insulation treatment. One insulation mechanism realizes the insulation operation of two workpieces, improves work efficiency, and does not occupy the horizontal area.

[0012] According to one embodiment of the present invention, a right lifting mechanism and a left lifting mechanism are provided below each of the operation conveying mechanisms. The right lifting mechanism is located in the right operation area and lifts the workpiece moved to the right operation area, so that the lifted workpiece is separated from the operation conveying mechanism in an up-and-down state. The left lifting mechanism is located in the left operation area and lifts the workpiece moved to the left operation area, so that the lifted workpiece is separated from the operation conveying mechanism in an up-and-down state. Thus, each operation area lifts and positions the workpiece moved to the operation area through the corresponding lifting mechanism, ensuring that the workpiece is in a stable and precise position during the dispensing process, avoiding deviations in the dispensing position due to factors such as workpiece shaking and displacement, thereby greatly improving the accuracy of dispensing.

[0013] According to one embodiment of the present invention, the dispensing equipment also includes: a first x-axis guide mechanism, a second x-axis guide mechanism, a first y-axis guide mechanism and a second y-axis guide mechanism, the first x-axis guide mechanism and the second x-axis guide mechanism are both arranged along the x-axis direction and are respectively installed on both sides of the working conveying mechanism; the first y-axis guide mechanism is mounted on the first x-axis guide mechanism and the second x-axis guide mechanism, and is located on the left side of the working conveying mechanism corresponding to the left working area, the left dispensing mechanism is connected to the first y-axis guide mechanism, and the left dispensing mechanism performs dispensing operations on the workpiece on the left working area; the second y-axis guide mechanism is mounted on the first x-axis guide mechanism and the second x-axis guide mechanism, and is located on the right side of the working conveying mechanism corresponding to the right working area, the right dispensing mechanism is connected to the second y-axis guide mechanism, and the right dispensing mechanism performs dispensing operations on the workpiece on the right working area. Therefore, due to the multiple parallel operation conveying mechanisms, the first x-axis guide mechanism and the second x-axis guide mechanism are respectively arranged on the outside of the head and tail operation conveying mechanisms, and then cooperate with the first y-axis guide mechanism and the second y-axis guide mechanism to provide a large-span motion track for the left dispensing mechanism and the right dispensing mechanism. The dual guide mechanism can provide stable support to ensure that the left dispensing mechanism and the right dispensing mechanism can achieve precise positioning in the x-axis and y-axis directions, thereby ensuring the dispensing accuracy. The left dispensing mechanism and the right dispensing mechanism can be independently driven to move on the guide mechanism, realizing dual-drive parallel operation. The two dispensing mechanisms can perform dispensing operations on workpieces in different operation areas at the same time, greatly shortening the production cycle and improving production efficiency.

[0014] According to one embodiment of the present invention, the loading equipment includes a loading and storage platform, a loading and lifting mechanism, a loading and connecting conveying mechanism and a loading and clamping mechanism. The loading and storage platform is used to store the workpiece to be processed. The loading and lifting mechanism is used to drive the loading and storage platform to rise and fall along the z-axis direction. The loading and clamping mechanism is installed on the loading and connecting conveying mechanism and is used to remove the workpiece to be processed from the loading and storage platform. The loading and connecting conveying mechanism is arranged between the loading and storage platform and the dispensing equipment, and is used to convey the workpiece to be processed to any one of the operating conveying mechanisms. Therefore, the loading and storage platform is lifted and lowered only in the z-axis direction through the loading and storage mechanism, and the workpieces to be processed on the loading and storage platform are distributed to each operating conveying mechanism in conjunction with the loading and storage mechanism that can move along the y-axis direction, so that the loading and storage platform can store more workpieces, and the overall machine size is more compact. Compared with the traditional loading and storage platform that is lifted and lowered along the z-axis and moved along the y-axis for docking and distribution, when the overall machine size is fixed, the traditional loading and storage platform moves along the y-axis for docking and distribution. As the number of operating conveying mechanisms increases, its docking stroke will be limited, and may not be able to meet the docking needs of all operating conveying mechanisms.

[0015] According to one embodiment of the present invention, the loading and connecting conveying mechanism includes a loading y-axis linear module and a loading and conveying device. The loading y-axis linear module is used to drive the loading and conveying device to move along the y-axis direction to connect the loading storage platform and each operating conveying mechanism. The loading and conveying device is used to convey the workpiece to be processed to any operating conveying mechanism.

[0016] According to one embodiment of the present invention, the loading and clamping mechanism is installed on the loading and conveying device, and the loading and clamping mechanism includes a loading jaw assembly and a jaw driving structure. The loading jaw assembly is arranged at the driving end of the jaw driving structure. The jaw assembly is used to clamp the workpiece, and the jaw driving structure is used to drive the jaw assembly to move along the z-axis and x-axis directions, so as to drive the workpiece to move to the loading and conveying device when the jaw assembly clamps the workpiece.

[0017] According to one embodiment of the present invention, the unloading equipment includes a unloading storage platform, a unloading lifting mechanism, a unloading connecting and conveying mechanism and an AOI (automatic optical inspection) inspection mechanism. The unloading storage platform is used to store inspected workpieces, and the unloading lifting mechanism is used to drive the unloading storage platform to rise and fall along the z-axis direction. The AOI inspection mechanism is arranged on one side of the unloading connecting and conveying mechanism, and is used to inspect the processed workpieces. The unloading connecting and conveying mechanism is arranged between the dispensing equipment and the unloading storage platform, and is used to take over the processed workpieces on any operating conveying mechanism. The unloading connecting and conveying mechanism transports the processed workpieces to the bottom of the AOI inspection mechanism for inspection, and transports the inspected workpieces to the unloading storage platform. Therefore, the unloading and storage platform is only lifted and lowered in the z-axis direction through the unloading and jacking mechanism, and the unloading and connecting conveying mechanism that can move along the y-axis direction can take over the processed workpieces on each operating conveying mechanism, and convey the processed workpieces to the bottom of the AOI inspection mechanism for inspection, and convey the inspected workpieces to the unloading and storage platform, so that the unloading and storage platform can store more workpieces, and the size of the whole machine is more compact. Compared with the traditional unloading and storage platform, which is lifted and lowered along the z-axis and moved along the y-axis for connecting and storing materials, when the size of the whole machine is fixed, the traditional unloading and storage platform moves along the y-axis for connecting and storing materials. As the number of operating conveying mechanisms increases, its connecting stroke will be limited, and may not be able to meet the connecting needs of all operating conveying mechanisms.

[0018] According to one embodiment of the present invention, the unloading connection and conveying mechanism includes a unloading y-axis linear module, a unloading conveying device and a unloading push rod device. The unloading conveying device is installed on the moving end of the unloading y-axis linear module. The unloading y-axis linear module is used to drive the unloading conveying device to move along the y-axis direction to connect with various operating conveying mechanisms, AOI inspection mechanisms and unloading storage platforms. The unloading push rod device is installed on the unloading conveying device to push the workpiece that has been inspected by the unloading conveying device to the unloading storage platform.

[0019] A dispensing operation method includes a loading device, a dispensing device, and a dispensing device sequentially arranged along a workpiece conveying direction. The dispensing device includes a left dispensing mechanism, a right dispensing mechanism, and multiple operation conveying mechanisms. The multiple operation conveying mechanisms are arranged in parallel. The right dispensing mechanism and the left dispensing mechanism are arranged opposite to each other and straddle the multiple operation conveying mechanisms. The straddle direction is perpendicular to the workpiece conveying direction. Each operation conveying mechanism is provided with a left operation area and a right operation area along the workpiece conveying direction. The operation method includes the following steps: Step S1: The loading device is used to convey the workpiece to be processed to any one of the working conveying mechanisms, and sequentially conveys two workpieces to be processed to the same working conveying mechanism. Based on the workpiece conveying direction, the workpiece to be processed is preferentially conveyed to the right working area, and then the other workpiece to be processed is conveyed to the left working area. Step S2: repeat step S1, and the loading equipment is used to transport the workpiece to be processed to multiple operation conveying mechanisms; Step S3: The right dispensing mechanism moves to the right operating area of ​​one of the operation conveying mechanisms through the three-axis motion mechanism, and after sequentially performing a dispensing operation on multiple workpieces conveyed to the right operating area and waiting for the next dispensing operation, the right dispensing mechanism can be moved to the right operating area of ​​another of the operation conveying mechanisms through the three-axis motion mechanism, and sequentially perform dispensing operations on multiple workpieces on the other right operating area. At the same time, the left dispensing mechanism moves to the left operating area of ​​one of the operation conveying mechanisms through the three-axis motion mechanism, and after sequentially performing a dispensing operation on multiple workpieces conveyed to the left operating area and in a waiting time for the next dispensing operation, the left dispensing mechanism can be moved to the left operating area of ​​another of the operation conveying mechanisms through the three-axis motion mechanism, and sequentially perform dispensing operations on multiple workpieces on the other left operating area; Step S4: The unloading device is used to receive two workpieces that have completed the dispensing operation on any one of the operation conveying mechanisms, and preferentially receives the workpieces on the right operation area, then receives the workpieces on the left operation area, and transports the workpieces that have completed the dispensing operation to the next process; Step S5: repeat step S4 to complete unloading and conveying of workpieces on which multiple operation conveying mechanisms have completed the dispensing operation.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0044] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0045] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0046] like Figures 1 to 18 , which is a preferred embodiment of the present invention, the multi-track dispensing operation equipment of this embodiment comprises: a loading device 2, a dispensing device 1 and a unloading device 3 arranged in sequence along the workpiece conveying direction. The workpiece conveying direction of this embodiment is the x-axis direction; The glue dispensing device 1 includes a left glue dispensing mechanism 102, a right glue dispensing mechanism 101 and four operation conveying mechanisms 103. The four operation conveying mechanisms 103 are arranged in parallel along the y-axis direction. The right glue dispensing mechanism 101 and the left glue dispensing mechanism 102 are arranged opposite to each other and straddle the four operation conveying mechanisms 103 along the y-axis direction. Each operation conveying mechanism 103 has a right operation area 104 and a left operation area 105 arranged in sequence along the x-axis direction. The left operation area 105 is close to the loading device 2, and the right operation area 104 is far away from the loading device 2 and close to the unloading device 3 relative to the left operation area 105. The left glue dispensing mechanism 102 performs glue dispensing on the workpiece transported to the left operation area 105, and the right glue dispensing mechanism 101 The glue dispensing operation is performed on the workpiece transported to the right working area 104. Based on the workpiece transport direction, the workpiece to be processed is preferentially transported to the right working area 104, and then the other workpiece to be processed is transported to the left working area 105. Therefore, the glue dispensing equipment 1 is designed with four tracks and eight workstations. The work conveying mechanism 103 is a structure for driving the carrier to move along the x-axis direction. The carrier 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 working area 104 corresponding to the right belt structure, the left working area 105 corresponding to the left belt structure is provided. This design of providing two groups of belt structures makes the structure more complicated and increases the cost. The loading device 2 is used to transport the workpiece to be processed to any one of the operation conveying mechanisms 103, and to sequentially transport two workpieces to be processed to the same operation conveying mechanism 103; The left glue dispensing mechanism 102 is used to sequentially perform glue dispensing operations on multiple workpieces conveyed to multiple left working areas 105 , and each workpiece in the left working area 105 is subjected to at least two glue dispensing operations; The right glue dispensing mechanism 101 is used to sequentially perform glue dispensing operations on multiple workpieces conveyed to multiple right working areas 104 , and each workpiece in the right working area 104 is subjected to at least two glue dispensing operations; The unloading device 3 is used to receive two workpieces that have completed the dispensing operation on any one of the operation conveying mechanisms 103 , and gives priority to receiving the workpieces on the right operation area 104 , and then receives the workpieces on the left operation area 105 .

[0047] Taking the right dispensing mechanism 101 as an example, for example, the right working areas 104 of the four working conveying mechanisms 103 are respectively provided with a carrier plate carrying workpieces, and each carrier plate carries three workpieces. The right dispensing mechanism 101 moves to the right working area 104 of the first working conveying mechanism 103, and performs the first dispensing operation on the three workpieces carried on the carrier plate of the right working area 104 in sequence, and when it is in the waiting time for the second dispensing operation to be performed on the three workpieces on the carrier plate, the right dispensing mechanism 101 moves to the right working area 104 of the second working conveying mechanism 103, and performs the first dispensing operation on the three workpieces carried on the carrier plate of the right working area 104 in sequence. The glue dispensing operation is performed on each workpiece in turn, and then the glue dispensing operation is performed on the three workpieces carried on the right working area 104 of the third working conveying mechanism 103 and the right working area 104 of the fourth working conveying mechanism 103 in sequence. The execution end of the right glue dispensing mechanism 101 returns to the right working area 104 of the first working conveying mechanism 103. At this time, the glue of the first workpiece on the carrying plate of the right working area 104 has fully filled the gap between the chip and the substrate, and the second glue dispensing operation can be performed; the right glue dispensing mechanism 101 repeats the above operations in a cycle until multiple glue dispensing operations on all workpieces in all right working areas 104 are completed.

[0048] Therefore, when the dispensing mechanism completes a dispensing operation and is in an idle period waiting for the next operation, it does not wait idle, but moves to the corresponding operation area of ​​other operation conveying mechanisms 103 to continue to perform the dispensing operation. The glue bottom filling delay time is used to enable the dispensing mechanism to process more workpieces, avoid idle waiting time of the equipment, and improve the overall production efficiency. The left dispensing mechanism 102 and the right dispensing mechanism 101 can both 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. In addition, the dispensing equipment 1 of a dispensing machine adopts a plurality of operation conveying mechanisms 103 in conjunction with the right dispensing mechanism 101 and the left dispensing mechanism 102, which solves the problem of increased machine floor space and increased cost caused by the traditional solution of increasing the number of dispensing machines to improve production efficiency.

[0049] Specifically, the number of glue dispensing operations on the workpiece on each operation conveying mechanism 103 is at least two. For large-particle FCBGA chip products, the number of glue dispensing operations on the workpiece on each operation conveying mechanism 103 is about 6 to 8 times. The optimal execution process of the right glue dispensing mechanism 101 or the left glue dispensing mechanism 102 is: after performing a glue dispensing operation from the working area of ​​the first operation conveying mechanism 103 to the working area of ​​the last operation conveying mechanism 103 in sequence, the glue on the workpiece in the working area of ​​the first operation conveying mechanism 103 just fully fills the gap between the chip and the substrate. At this time, the right glue dispensing mechanism 101 or the left glue dispensing mechanism 102 returns to the first operation conveying mechanism 103 again, and performs the next glue dispensing operation on the workpiece in the working area of ​​the operation conveying mechanism 103. The cycle is repeated until all glue dispensing operations on the workpieces on all operation conveying mechanisms 103 are completed, avoiding idle waiting time of the equipment, maximizing the balance of the interval time between the two glue dispensing operations of the workpiece, and improving overall production efficiency.

[0050] In a preferred embodiment, the right glue dispensing mechanism 101 and the left glue dispensing mechanism 102 can not only perform glue dispensing operations on each workpiece on the operation conveying mechanism 103, but also perform mounting operations.

[0051] In a preferred embodiment, the dispensing equipment 1 further includes 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 operation conveying mechanisms 103 is adapted, and one operation conveying mechanism 103 corresponds to one preheating mechanism 106 and one heat preservation mechanism 107; the preheating mechanism 106 is located between the feeding device 2 and the operation conveying mechanism 103, and receives two workpieces to be processed outputted in sequence by the feeding device 2. The preheating mechanism 106 is used to preheat the two workpieces to be processed moved to the preheating mechanism 106. After the two workpieces to be processed are preheated, one of the workpieces to be processed is prioritized. The workpiece is transported to the right working area 104 of the corresponding working conveying mechanism 103, and then the other workpiece to be processed is transported to the left working area 105 of the corresponding working conveying mechanism 103; the insulation mechanism 107 is located between the working conveying mechanism 103 and the unloading equipment 3, and the insulation mechanism 107 insulates the two workpieces that have completed the dispensing operation and are moved to the insulation mechanism 107. Among them, the workpiece in the right working area 104 is first transported to the insulation mechanism 107, and the workpiece in the left working area 105 is transported to the insulation mechanism 107 after passing through the right working area 104. The insulation mechanism 107 pushes the two workpieces that have completed dispensing to the unloading equipment 3 in turn.

[0052] In a preferred embodiment, the preheating mechanism 106 includes an upper preheating station 106-1 and a lower preheating station 106-2 that can move up and down. The upper preheating station 106-1 and the lower preheating station 106-2 are stacked in the up and down directions. Two workpieces to be processed are respectively transported 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 transports the preheated workpiece to the right working area 104 first, and the other preheating station moves in the up and down directions and transports the preheated workpiece to the left working area 105. The upper preheating station 106-1 and the lower preheating station 106-2 can be stacked and installed on the preheating installation platform 106-3, and the preheating installation platform 106-3 is installed on the moving end of the preheating jacking mechanism 106-4. The preheating jacking mechanism 106-4 refers to a component that can drive an object to move in a straight line. The preheating jacking mechanism 106-4 can be a driving cylinder, a hydraulic cylinder, or an electric push rod. 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 along the z-axis direction to connect with the loading device 2 or the working conveying mechanism 103, thereby realizing the loading, preheating and unloading of the two workpieces to be processed. Figure 19 As shown, both the upper preheating station 106-1 and the lower preheating station 106-2 have a conveyor belt 106-5 for conveying the workpiece and a heating lifting module 106-6. The conveyor belt 106-5 is used to convey the workpiece along the x-axis direction. Here, the conveyor belt 106-5 refers to two conveyor belts spaced apart along the x-axis direction. The heating lifting module 106-6 is arranged between the two conveyor belts and is located below the conveyor belts. The heating lifting module 106-6 refers to when the workpiece is conveyed to the preheating station by the conveyor belt 106-5. When the upper and lower preheating stations 106-1 and 106-2 are stacked in the vertical direction, the equipment can be reduced in horizontal direction. The upper and lower preheating stations 106-1 and 106-2 can be moved vertically to connect with the conveyor belt 106-5, so that the preheated workpieces can be transported to the corresponding working area on the conveyor belt 103 for subsequent dispensing.

[0053] Specifically, the upper and lower preheating stations can preheat the workpiece simultaneously or alternately. Specifically, the simultaneous operation process is: when the upper and lower preheating stations complete the preheating of the workpiece at the same time, one of the preheating stations will first transport the preheated workpiece to the right working area 104, and the other preheating station will move along the up and down directions and transport the other preheated workpiece to the left working area 105; the alternating operation process is: when one preheating station completes preheating, and during the time of lifting and transporting the workpiece to its corresponding working area, the other preheating station simultaneously preheats the workpiece placed thereon. When the upper workpiece completely leaves the preheating station, the other preheating station also completes preheating and lifts to transport the workpiece to its corresponding working area, thereby reducing the waiting time of the workpiece in the preheating link and speeding up the speed of the workpiece entering the subsequent dispensing operation. The upper and lower preheating stations 106-2 can work together to ensure that there are always preheated workpieces ready to enter the working conveying mechanism 103 for dispensing operation, thereby achieving production continuity and improving overall production efficiency.

[0054] In a preferred embodiment, the insulation mechanism 107 includes an upper insulation station 107-1 and a lower insulation station 107-2 that can move up and down. The upper insulation station 107-1 and the lower insulation station 107-2 are stacked in the up and down directions. One of the upper insulation station 107-1 and the lower insulation station 107-2 is used to give priority to the workpiece on the right working area 104 that has completed the gluing operation, and the other insulation station moves in the up and down directions to take over the workpiece on the left working area 105 that has completed the gluing operation. The upper insulation station 107-1 and the lower insulation station 107-2 are both used to insulate the workpiece. The upper insulation station 107-1 and the lower insulation station 107-2 can be stacked and installed on the insulation installation platform 107-3, and the insulation installation platform 107-3 is installed on the moving end of the insulation jacking mechanism 107-4. The insulation jacking mechanism 107-4 refers to a component that can drive an object to move in a straight line. The insulation jacking mechanism 107-4 can be a driving cylinder, a hydraulic cylinder or an electric push rod, etc. The insulation jacking mechanism 107-4 drives the upper insulation station 107-1 and the lower insulation station 107-2 to move as a whole along the z-axis direction to connect with the operation conveying mechanism 103 or the unloading device 3, thereby realizing the loading, insulation and unloading of the two workpieces to be processed. The upper insulation station 107-1 and the lower insulation station 107-2 also have a conveyor belt 106-5 and a heating lifting module 106-6 for conveying workpieces. Therefore, the upper insulation station 107-1 and the lower insulation station 107-2 are stacked in the up and down directions to reduce the horizontal extension range of the equipment, and the upper insulation station 107-1 and the lower insulation station 107-2 that can move up and down are used to connect the operation conveying mechanism 103, so that the workpieces after gluing in the right and left working areas 105 can be conveyed to the corresponding insulation stations for subsequent insulation treatment, thereby realizing the insulation operation of the two workpieces.

[0055] Specifically, the upper and lower insulation stations can perform insulation treatment on the workpiece simultaneously or alternately. Specifically, the simultaneous operation process is: one insulation station is used to receive the workpiece after the gluing operation on the right working area 104, and the other insulation station moves along the up and down directions to receive the workpiece after the gluing operation on the left working area 105, and then the upper and lower insulation stations perform insulation treatment at the same time; the alternating operation process is: one insulation station receives the workpiece after the gluing operation on its corresponding working area and starts insulation treatment. During the insulation time, the other insulation station The upper and lower insulation stations 107-2 can be raised and lowered to receive the workpiece after the dispensing operation in its corresponding operating area and start the insulation treatment. During the insulation treatment at another insulation station, the insulation of the previous insulation station is completed, and the workpiece after the insulation treatment can be transported to the next process and repeated. This reduces the waiting time of the workpiece in the insulation link and speeds up the speed of the workpiece entering the subsequent inspection operation. The upper and lower insulation stations 107-2 can work together to ensure that there are always workpieces ready to enter the insulation station for insulation treatment, thereby achieving production continuity and improving overall production efficiency.

[0056] In a preferred embodiment, a right lifting mechanism 108 and a left lifting mechanism 109 are provided below each work conveying mechanism 103. The right lifting mechanism 108 is located in the right work area 104. 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 separated from the work conveying mechanism 103 in an up-and-down state. The left lifting mechanism 109 is located in the left work area 105. 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 separated from the work conveying mechanism 103 in an up-and-down state. The right lifting mechanism 108 and the left lifting mechanism 109 are components that can drive an object to move in a straight line. The right lifting mechanism 108 and the left lifting mechanism 109 can be driving cylinders, hydraulic cylinders, or electric push rods. Therefore, each working area lifts and positions the workpiece moved to the working area through the corresponding lifting mechanism, which can ensure that the workpiece is in a stable and precise position during the dispensing process, avoiding the deviation of the dispensing position due to factors such as workpiece shaking and displacement, thereby greatly improving the accuracy of dispensing. The lifting mechanism is used to lift the workpiece, so that the workpiece and the working conveying mechanism 103 are in an upper and lower separated state. Compared with the method of moving the working conveying mechanism 103 along the z-axis direction to achieve this separation state, it has the advantages of simple structure and easy implementation. If the working conveying mechanism 103 is moved up and down, its structure will be more complicated and the cost will increase.

[0057] In a preferred embodiment, the dispensing device 1 further includes: a first x-axis guide mechanism 110, a second x-axis guide mechanism 111, a first y-axis guide mechanism 112, and a second y-axis guide mechanism 113. The first x-axis guide mechanism 110 and the second x-axis guide mechanism 111 are both arranged along the x-axis direction and are respectively installed on both sides of the operation conveying mechanism 103; the first y-axis guide mechanism 112 is mounted on the first x-axis guide mechanism 110 and the second x-axis guide mechanism 111, and is located on the left side of the operation conveying mechanism 103 corresponding to the first x-axis guide mechanism 110 and the second x-axis guide mechanism 111. In the left working area 105, the left glue dispensing mechanism 102 is connected to the first y-axis guide mechanism 112, and the left glue dispensing mechanism 102 performs glue dispensing operations on the workpiece on the left working area 105; the second y-axis guide mechanism 113 is mounted on the first x-axis guide mechanism 110 and the second x-axis guide mechanism 111, and is located on the right side of the work conveying mechanism 103 corresponding to the right working area 104, the right glue dispensing mechanism 101 is connected to the second y-axis guide mechanism 113, and the right glue dispensing mechanism 101 performs glue dispensing operations on the workpiece on the right working area 104. Therefore, due to the multiple parallel operation conveying mechanisms 103, the first x-axis guide mechanism 110 and the second x-axis guide mechanism 111 are respectively arranged on the outside of the head and tail operation conveying mechanisms 103, and then cooperate with the first y-axis guide mechanism 112 and the second y-axis guide mechanism 113 to provide a large-span motion track for the left dispensing mechanism 102 and the right dispensing mechanism 101. The dual guide mechanism 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 the dispensing accuracy. The left dispensing mechanism 102 and the right dispensing mechanism 101 can both be independently driven to move on the guide mechanism, realizing dual-drive parallel operation. The two dispensing mechanisms can perform dispensing operations on workpieces in different operation areas at the same time, greatly shortening the production cycle and improving production efficiency.

[0058] Specifically, a first drive motor and a second drive motor are provided on the first x-axis guide mechanism 110. The second drive motor is used to drive the right dispensing mechanism 101 to move along the x-axis direction to perform dispensing operations on the workpiece on the right working area 104. The first drive motor is used to drive the left dispensing mechanism 102 to move along the x-axis direction to perform dispensing operations on the workpiece on the left working area 105.

[0059] Preferably, the first drive motor and the second drive motor may be linear motors. The reason for using linear motors is that linear motors have high speed and high thrust, which further improves working efficiency.

[0060] The first drive motor, the second drive motor, the first x-axis guide mechanism 110, the second x-axis guide mechanism 111, the first y-axis guide mechanism 112 and the second y-axis guide mechanism 113 form a rigid dual-drive gantry with high processing precision, large load capacity and fast response speed. The first y-axis guide mechanism 112 is driven by the first drive motor, which ensures the dispensing accuracy of the left dispensing mechanism 102. Compared with installing a drive motor on the first x-axis guide mechanism 110 and the second x-axis guide mechanism 111 respectively to jointly drive the first y-axis guide mechanism 112 to move, the driving method of the two motors is prone to cause the first y-axis guide mechanism 112 to tilt due to the speed error of the two motors, thereby affecting the dispensing accuracy of the right dispensing mechanism 101.

[0061] In a preferred embodiment, a first z-axis guide mechanism 114 is provided on the first y-axis guide mechanism 112, and a second z-axis guide mechanism 115 is provided on the second y-axis guide mechanism 113. The left dispensing mechanism 102 is connected to the first z-axis guide mechanism 114, and the right dispensing mechanism 101 is connected to the second z-axis guide mechanism 115. The first x-axis guide mechanism 110, the second x-axis guide mechanism 111, the first y-axis guide mechanism 112, and the first z-axis guide mechanism 114 constitute a three-axis motion mechanism for driving the left dispensing mechanism 102 to move along the xyz direction to perform a dispensing operation on the workpiece in the left working area 105. The first x-axis guide mechanism 110, the second x-axis guide mechanism 111, the second y-axis guide mechanism 113, and the second z-axis guide mechanism 115 constitute a three-axis motion mechanism for driving the right dispensing mechanism 101 to move along the xyz direction to perform a dispensing operation on the workpiece in the right working area 104.

[0062] 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 a rail structure with a certain length, and a transmission unit is also provided on the rail structure for pushing the product to slide along the length direction of the rail structure. The transmission unit can be a slide rail slider structure.

[0063] In a preferred embodiment, the right dispensing mechanism 101 includes a glue weighing module, a glue clearing module and a glue dispensing module with corresponding functions; the left dispensing mechanism 102 includes a glue weighing module, a glue clearing module and a glue dispensing module with corresponding functions.

The loading and storage platform 201 is used to store the workpiece to be processed. The loading and lifting mechanism 202 is used to drive the loading and storage platform 201 to rise and fall along the z-axis direction. The loading and clamping mechanism 204 is installed on the loading and connecting conveying mechanism 203 and is used to remove the workpiece to be processed from the loading and storage platform 201. The loading and connecting conveying mechanism 203 is arranged between the loading and storage platform 201 and the dispensing equipment 1, and is used to convey the workpiece to be processed to any preheating mechanism 106. Therefore, the loading and storage platform 201 is lifted and lowered only in the z-axis direction through the loading and storage platform 201 lifting mechanism 202, and the loading and storage platform 201 is distributed to each preheating mechanism 106 in cooperation with the loading and storage platform 201 that can move along the y-axis direction, so that the loading and storage platform 201 can store more workpieces, and the size of the whole machine is more compact. Compared with the traditional loading and storage platform 201 that is lifted and lowered along the z-axis and moved along the y-axis for docking and distribution, when the size of the whole machine is fixed, the traditional loading and storage platform 201 is moved along the y-axis for docking and distribution. As the number of working conveying mechanisms 103 increases, its docking stroke will be limited, and may not be able to meet the docking needs of all working conveying mechanisms 103.

[0065] Specifically, the loading and storage platform 201 refers to a plate-like component with a certain area, which can hold multiple loading boxes 205, and the loading boxes 205 contain workpieces to be processed. The loading and lifting mechanism 202 refers to a component that can drive an object to move in a straight line. The loading and lifting mechanism 202 can be a driving cylinder, a hydraulic cylinder, or an electric push rod. Preferably, see Figure 11 As shown, the loading and lifting mechanism 202 includes: a driving motor, a screw and a nut mounting seat. The screw is directly connected to the motor shaft of the driving motor, the screw is extended along the z-axis direction, the nut mounting seat is sleeved on the screw, and the loading and storage platform 201 is installed on the nut mounting seat.

The loading conveying device 203-2 is used to transport the workpiece to be processed to any preheating mechanism 106. The loading conveying device 203-2 refers to a transport structure for transporting products. Specifically, the loading conveying device 203-2 can be a conveyor belt structure.

[0067] The loading and clamping mechanism 204 is mounted on the loading and conveying device 203-2. The loading and clamping mechanism 204 includes a loading clamping jaw assembly 204-1 and a clamping jaw drive structure 204-2. The loading and clamping jaw assembly 204-1 is disposed at the drive end of the clamping jaw drive structure 204-2. The clamping jaw assembly is used to clamp the workpiece, and the clamping jaw drive structure 204-2 is used to drive the clamping jaw assembly to move, so that when the clamping jaw assembly clamps the workpiece, the workpiece is moved together with the loading and conveying device 203-2. The loading and conveying device 203-2 is used to transport the product to each preheating mechanism 106. Specifically, two groups of loading and clamping mechanisms 204 are provided, and the two groups of loading and clamping mechanisms 204 are respectively provided on both sides of the workpiece. This design is adopted because large-particle FCBGA chip products are large in size and heavy in weight. The two groups of loading and clamping mechanisms 204 clamp both sides of the workpiece and pull the workpiece to prevent the workpiece from shifting. Specifically, the jaw assembly refers to a component that can clamp an object, and the jaw assembly can be a jaw cylinder, a hydraulic jaw, or the like. The jaw drive structure 204-2 is used to drive the jaw assembly to move along the x-axis and the z-axis. When working, the jaw drive structure 204-2 can drive the jaw assembly to approach a workpiece on the loading and storage platform 201 along the x-axis and clamp the workpiece. After the workpiece is clamped, the jaw drive structure 204-2 drags the workpiece along the x-axis to the loading and conveying device 203-2. The jaw assembly then opens, and the jaw drive structure 204-2 continues to retreat along the x-axis to the outside of the workpiece. The jaw assembly closes, and the jaw drive structure 204-2 drives the jaw assembly down along the z-axis to prevent interference with the workpiece conveying. Finally, the loading and conveying device 203-2 and the loading y-axis linear module 203-1 are used to transport the workpiece to each preheating mechanism 106. The coordination of the clamping jaw assembly, the clamping jaw driving structure 204 - 2 and the loading and conveying device 203 - 2 can make the loading and transportation of the product more convenient.

[0068] In a preferred embodiment, the unloading equipment 3 includes a unloading storage platform 301, a unloading lifting mechanism 302, a unloading connecting and conveying mechanism 303 and an AOI detection mechanism 304. The unloading storage platform 301 is used to store the inspected workpieces, the unloading lifting mechanism 302 is used to drive the unloading storage platform 301 to rise and fall along the z-axis direction, the AOI detection mechanism 304 is arranged on one side of the unloading connecting and conveying mechanism 303, and is used to inspect the processed workpieces, the unloading connecting and conveying mechanism 303 is arranged between the dispensing equipment 1 and the unloading storage platform 301, and is used to receive the processed workpieces on any one of the insulation mechanisms 107, the unloading connecting and conveying mechanism 303 transports the processed workpieces to the bottom of the AOI detection mechanism 304 for inspection, and transports the inspected workpieces to the unloading storage platform 301. Therefore, the unloading and storage platform 301 is only lifted and lowered in the z-axis direction through the unloading and lifting mechanism 302, and the unloading and connecting conveying mechanism 303 which can move along the y-axis direction can receive the processed workpieces on each insulation mechanism 107, and convey the processed workpieces to the bottom of the AOI inspection mechanism 304 for inspection, and convey the inspected workpieces to the unloading and storage platform 301, so that the unloading and storage platform 301 can store more workpieces, and the size of the whole machine is more compact. Compared with the traditional unloading and storage platform 301 which is lifted and lowered along the z-axis and moved along the y-axis for connecting and storing materials, when the size of the whole machine is fixed, the traditional unloading and storage platform 301 moves along the y-axis for connecting and storing materials. As the number of working conveying mechanisms 103 increases, its connecting stroke will be limited, and may not be able to meet the connecting needs of all working conveying mechanisms 103.

[0069] Specifically, the unloading and storage platform 301 refers to a plate-like component with a certain area, and the plate-like component can place multiple unloading boxes 305, and the unloading boxes 305 contain processed and inspected workpieces. The unloading and lifting mechanism 302 refers to a component that can drive an object to move in a straight line direction. The unloading and lifting mechanism 302 can be a driving cylinder, a hydraulic cylinder, a motor screw mechanism or an electric push rod, etc.

[0070] Specifically, the unloading connection and conveying mechanism 303 includes a unloading y-axis linear module 303-1, a unloading conveying device 303-2 and a unloading push rod device 303-3. The unloading conveying device 303-2 is installed on the moving end of the unloading y-axis linear module 303-1. The unloading y-axis linear module 303-1 is used to drive the unloading conveying device 303-2 to move along the y-axis direction to connect with each insulation mechanism 107, AOI detection mechanism 304 and unloading storage platform 301. The unloading conveying device 303-2 refers to a transportation structure for transporting products. Specifically, the unloading conveying device 303-2 can be a conveyor belt structure. The unloading push rod device 303-3 is mounted on the unloading conveyor 303-2. It includes a lifting slide 303-3-1 that can move along the z-axis, and a push rod assembly 303-3-2 mounted on the lifting slide 303-3-1. The push rod assembly 303-3-2 has a push rod that can move along the x-axis. During operation, after the AOI inspection mechanism 304 completes inspection, the unloading conveyor 303-2 approaches the unloading and storage platform 301. After the unloading conveyor 303-2 transfers at least a portion of the workpiece to the unloading and storage platform 301, the lifting slide 303-3-1 rises, and the push rod finally pushes the entire workpiece along the x-axis into the unloading hopper 305 on the unloading and storage platform 301. The coordination between the unloading push rod device 303-3 and the unloading conveyor 303-2 facilitates the unloading and transportation of products.

[0071] Specifically, the AOI detection mechanism 304 includes: a three-axis mobile module 304-1 and a visual detection module 304-2.

The visual detection module 304-2 is used to detect the workpiece that has been glued and cured on the blanking and connecting conveying mechanism 303.

[0072] The dispensing method of the present invention is as follows: Step S1: stacking the workpieces on the loading and storage platform 201; Step S2: The loading and connecting conveying mechanism 203 approaches the loading and storage platform 201, and the loading and lifting mechanism 202 drives the loading and storage platform 201 to move along the z-axis direction, so that the uppermost workpiece of the loading and storage platform 201 is flush with the loading and connecting conveying mechanism 203; Step S3: The clamping jaw driving structure 204-2 drives the clamping jaw assembly to approach the uppermost workpiece on the loading and storage platform 201 and clamp the workpiece. After the workpiece is clamped, the clamping jaw driving structure 204-2 drags the workpiece to the loading and conveying device 203-2. Then, the clamping jaw assembly opens, and the clamping jaw driving structure 204-2 retreats to the outside of the workpiece, and the clamping jaw driving structure 204-2 drives the clamping jaw assembly to descend. Step S4: The loading and connecting conveying mechanism 203 drives the workpiece to move to any preheating mechanism 106. Any preheating station 106-1 or 106-2 is raised or lowered to be flush with the loading and connecting conveying mechanism 203. The loading and connecting conveying mechanism 203 conveys the workpiece to the preheating station, and the preheating station preheats the workpiece. Step S5, repeating the above steps S2 to S4 until the workpieces on the eight preheating stations are transported; Step S6: After each preheating mechanism 106 completes preheating of the workpiece, one of the preheating stations first transports the preheated workpiece to the right working area 104, and the other preheating station moves in the up and down direction and transports the preheated workpiece to the left working area 105; Step S7: The right lifting mechanism 108 lifts the workpiece moved to the right working area 104 along the z-axis direction, so that the lifted workpiece is separated from the working conveying mechanism 103 in a vertically separated state. The left lifting mechanism 109 lifts the workpiece moved to the left working area 105 along the z-axis direction, so that the lifted workpiece is separated from the working conveying mechanism 103 in a vertically separated state. Step S8: The right dispensing mechanism 101 is moved to the right operating area 104 of one of the operation conveying mechanisms 103 through the three-axis motion mechanism, and after sequentially performing one dispensing operation on multiple workpieces conveyed to the right operating area 104 and in the waiting time for the next dispensing operation, the right dispensing mechanism 101 is moved to the right operating area 104 of another operation conveying mechanism 103 through the three-axis motion mechanism, and sequentially performs dispensing operations on multiple workpieces on the other right operating area 104, and the cycle is repeated until multiple dispensing operations are performed on all workpieces on all right operating areas 104; The left dispensing mechanism 102 is moved to the left operating area 105 of one of the operation conveying mechanisms 103 through the three-axis motion mechanism, and after sequentially performing a dispensing operation on multiple workpieces conveyed to the left operating area 105 and in a waiting time for performing the next dispensing operation, the left dispensing mechanism 102 is moved to the left operating area 105 of another operation conveying mechanism 103 through the three-axis motion mechanism, and sequentially performs dispensing operations on multiple workpieces on the other left operating area 105, and the cycle is repeated until multiple dispensing operations are performed on all workpieces on all left operating areas 105; Step S9: After the workpiece is glued, 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; Step S10: The workpiece conveying mechanism 103 preferentially conveys the workpiece on the right work area 104 that has completed the dispensing process to one of the heat preservation stations. The other heat preservation station then moves in the up-down direction to receive the workpiece on the left work area 105 that has completed the dispensing process.
