Description

Technical Field

[0001] This invention relates to the field of workpiece transfer technology, and more particularly to a double-layer workpiece transfer device. Background Technology

[0002] Underfill dispensing is a common back-end packaging and testing process in semiconductor manufacturing. In traditional dispensing machine layout designs, preheating stations, dispensing stations, and insulation stations are typically set up sequentially along the production line. When processing large-sized chips, to ensure single-machine production efficiency, multiple work areas are usually set up at the dispensing station. Each work area can accommodate a carrier for the workpiece. Based on this design, the number of work areas in the preheating and insulation stations must also be consistent with the number of work areas in the dispensing station to ensure a smooth connection of the entire production process.

[0003] However, if the work areas in the preheating and insulation stations adopt the conventional flat layout within the track, the length of the dispensing machine in the production line direction will increase significantly. This layout not only occupies more production space, but is also unsuitable for some production scenarios with limited space, thus restricting the flexible application of the dispensing machine in different production environments. Summary of the Invention

[0004] The technical problem solved by this invention is that the preheating station and the insulation station work areas are laid out in a flat layout, which results in the equipment occupying a large space.

[0005] To address this, the present invention provides a double-layer workpiece conveying device, which reduces the device's footprint through a stacked design.

[0040] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. 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.

[0041] The workpiece double-layer conveying device of the present application can be located between the feeding mechanism and the working mechanism, or between the working mechanism and the discharging mechanism. When the workpiece double-layer conveying device is located between the feeding mechanism and the working mechanism, it is used for preheating and conveying workpieces, and can sequentially convey two workpieces to the working mechanism. When the workpiece double-layer conveying device is located between the working mechanism and the discharging mechanism, it is used for heat preservation and conveying workpieces, and can sequentially receive two workpieces conveyed by the working mechanism.

[0042] Preferably, the workpiece double-layer conveying device of the present application can also be used on other devices with limited horizontal space and requiring sequential conveying of multiple workpieces, and can realize sequential conveying of workpieces by using vertical space, effectively solving the problem of large equipment footprint.

[0043] Specifically, as shown in FIG. 1, the workpiece double-layer conveying device of the present application comprises a conveying mechanism 1 and a conveying mechanism 2. Figures 1 to 11The workpiece double-layer conveying device of the preferred embodiment of the present application comprises a jacking station 1, an upper conveying station 2 and a lower conveying station 3. The upper conveying station 2 and the lower conveying station 3 are stacked in the up-down direction on a mounting platform 4. The mounting platform 4 is mounted on the moving end of the jacking station 1. The jacking station 1 is used to drive the upper conveying station 2 and the lower conveying station 3 to synchronously ascend and descend. The upper conveying station 2 comprises an upper heating tool 201, an upper conveying mechanism 202 and an upper jacking mechanism 203. The upper heating tool 201 is arranged on the moving end of the upper jacking mechanism 203. The upper heating tool 201 is provided with a heating element 5. The upper heating tool 201 is used to heat the workpiece. The upper conveying mechanism 202 is used to convey one workpiece. The upper jacking mechanism 203 is arranged below the upper conveying mechanism 202 and can be used to jack the upper heating tool 201, so that the workpiece is separated from the upper conveying mechanism 202 in the up-down direction. The lower conveying station 3 comprises a lower heating tool 301, a lower conveying mechanism 303 and a lower jacking mechanism 304. The lower heating tool 301 is arranged on the moving end of the lower jacking mechanism 304. The lower heating tool 301 is provided with a heating element 5. The lower heating tool 301 is used to heat the workpiece. The lower conveying mechanism 303 is used to convey another workpiece. The lower jacking mechanism 304 is arranged below the lower conveying mechanism 303 and can be used to jack the lower heating tool 301, so that the workpiece is separated from the lower conveying mechanism 303 in the up-down direction.

[0044] Thus, the upper conveying mechanism 202 is used to realize the feeding and discharging of the workpiece. After the workpiece is conveyed to the position, the upper jacking mechanism 203 is used to jack the upper heating tool 201 in the up-down direction. After the upper heating tool 201 is jacked to contact the workpiece, the upper heating tool 201 continues to be jacked upward, so that the workpiece is separated from the upper conveying mechanism 202. The upper conveying mechanism 202 is prevented from running in the high-temperature environment for a long time, the service life of the conveying mechanism is prolonged, the workpiece is placed on the upper heating tool 201 and heated. The lower conveying mechanism 303 is used to realize the feeding and discharging of the workpiece. After the workpiece is conveyed to the position, the lower jacking mechanism 304 is used to jack the lower heating tool 301 in the up-down direction. After the lower heating tool 301 is jacked to contact the workpiece, the lower heating tool 301 continues to be jacked upward, so that the workpiece is separated from the lower conveying mechanism 303. The lower conveying mechanism 303 is prevented from running in the high-temperature environment for a long time, the service life of the lower conveying mechanism 303 is prolonged, and the workpiece is placed on the lower heating tool 301 and heated. Preferably, when the workpiece does not need to be heated, the upper heating tool 201 and the lower heating tool 301 can be replaced by other positioning tool clamps. After the workpiece is separated from the conveying mechanism, the workpiece can be accurately placed on the tool clamp, so that other operation mechanisms can operate the workpiece on the tool clamp.

[0045] The conventional preheating station and heat preservation station adopt a conventional track inner paving layout mode, with the increase of the number of operation areas, the equipment continuously extends in the horizontal direction, resulting in a substantial increase in the size of the single machine, and occupies a large amount of valuable production site space. The heating station of the present application adopts a stacked design, and the multiple operation areas are arranged in the vertical direction, making full use of the vertical space, and the volume is small, and under the premise of not increasing the horizontal area of the equipment, the matching with the dispensing operation station operation area number is realized, and the problem of large equipment floor space is effectively solved. The position of the two-layer heating station in the vertical direction is adjusted by the jacking station 1, and the operation of each layer of the heating station can be independently carried out, and they do not interfere with each other. When a layer of heating station has completed the preheating or heat preservation operation, the dispensing device can be directly connected to the workpiece conveying to carry out dispensing operation, and the workpiece on the other layer of heating station is still continuing the corresponding heating treatment. This parallel operation mode ensures the continuity of the production process, and in the production process, the workpiece on the rear position does not need to wait for the workpiece on the front position to complete the heating operation before conveying and dispensing, avoiding the situation that the subsequent position waits for the operation of a certain position to be completed, causing the production line to be blocked, thereby improving the production efficiency.

[0046] In a preferred embodiment, the jacking station 1 comprises a jacking motor 101, a jacking screw 102, a nut mounting seat 103, a jacking rod 104, a jacking sliding block 105, a jacking sliding rail 106 and a base 107, the jacking sliding rail 106 is installed on the base 107 in the vertical direction, the jacking sliding block 105 is slidingly installed on the jacking sliding rail 106, the jacking sliding block 105 is connected with the nut mounting seat 103, the jacking rod 104 is installed on the nut mounting seat 103 in the vertical direction, the installation platform 4 is installed on the jacking rod 104, the nut mounting seat 103 is sleeved on the jacking screw 102, and the jacking screw 102 is arranged on the output end of the jacking motor 101 in the vertical direction. Thus, through the cooperation of the jacking motor 101, the jacking screw 102 and the sliding block sliding rail structure, the height of the upper and lower conveying stations 3 is accurately, stably and flexibly adjusted. The jacking motor 101 as a driving source can accurately control the rotation number and angle of the jacking screw 102. Since the nut mounting seat 103 is threadedly connected with the jacking screw 102, the rotation of the screw rod will be converted into the linear motion of the nut mounting seat 103, thereby driving the jacking rod 104, the installation platform 4 and the upper and lower conveying stations 3 to move accurately in the vertical direction. Compared with using a jacking cylinder 203-1 as a driving source (only two fixed positions of jacking can be achieved), the design of the present application can accurately dock the upper and lower conveying stations 3 to any set height position.

[0047] Specifically, the jacking motor 101 and the jacking screw 102 are connected through a transmission structure, which can be a belt transmission structure, a chain transmission structure or a gear transmission structure, etc. The jacking motor 101 and the jacking screw 102 are indirectly connected through the transmission structure, which has obvious advantages in reducing the load of the motor, improving the transmission performance, enhancing the stability of the equipment, etc. compared with the direct connection mode of the motor shaft of the jacking screw 102. Preferably, the jacking motor 101 is a servo motor.

Thus, through the pulling design, the lower heating tool 301 can be quickly and conveniently replaced, the workpiece changeover time is shortened, the flexibility and response speed of the production line are improved, and the problem of the lower conveying station 3 being blocked by the upper conveying station 2 or other components on the whole machine device and being inconvenient to replace the tool, maintain or clean the device is solved.

[0049] In a preferred embodiment, the fixed rail platform 302-1 comprises a bottom plate part 302-1-1 and two side rail parts 302-1-2, the bottom plate part 302-1-1 being installed at the moving end of the lower jacking mechanism 304, the two side rail parts 302-1-2 being respectively installed on the two sides of the bottom plate part 302-1-1, the bottom plate part 302-1-1 being provided with a guide bearing 302-3, the lower end of the pulling platform 302-2 being provided with a guide groove 302-4 for the guide bearing 302-3 to slide, the two sides of the pulling platform 302-2 being provided with the guide bearing 302-3, the two side rail parts 302-1-2 being respectively arranged on the two sides of the pulling platform 302-2, and the side rail part 302-1-2 being provided with the guide groove 302-4 for the guide bearing 302-3 to slide. Thus, the pulling operation is smoother through the guide bearing 302-3, the guide groove 302-4 arranged at the lower end of the pulling platform 302-2 cooperates with the guide bearing 302-3 on the bottom plate part 302-1-1 to form a transverse constraint mechanism, which can prevent the pulling platform 302-2 from moving left and right during the pulling process, and the guide bearings 302-3 on the two sides of the pulling platform 302-2 interact with the guide grooves 302-4 on the side rail parts 302-1-2 to form a longitudinal constraint structure, which can prevent the pulling platform 302-2 from moving up and down during the pulling process.

[0050] In a preferred embodiment, the pull-out platform 302-2 is provided with a manual quick plug latch 302-5, and the fixed platform 302-1 is provided with a plug hole, and the manual quick plug latch 302-5 is operatively inserted into the plug hole to fix the pull-out platform 302-2. Thus, the design of the manual quick plug latch 302-5 enables the operator to quickly and easily fix the pull-out platform 302-2 on the fixed platform 302-1, or quickly unlock when the pull-out platform 302-2 needs to be moved.

Thus, through the cooperation of the upper blocking mechanism with the upper conveying mechanism 202 and the upper lifting mechanism 203, the precise control and orderly connection of the workpiece conveying, positioning and heating processes are realized. The upper blocking mechanism is arranged in front of the workpiece conveying direction, and when the workpiece is blocked by the upper blocking block 205 during the conveying process, it indicates that the workpiece has been accurately conveyed to the designated position. The physical blocking mode provides a reliable basis for the positioning of the workpiece, avoids the deviation of the workpiece position due to conveying errors or inertia, ensures that each workpiece can be subjected to subsequent heating operations at the same position, improves the consistency of production and the quality of products, and after the heating is completed, the upper blocking cylinder 204 controls the upper blocking block 205 to descend, thereby removing the blocking of the workpiece, so that the workpiece can continue to advance along the conveying direction and enter the next production process.

[0052] In a preferred embodiment, the lower conveying mechanism 303 is provided with a lower blocking mechanism, which is arranged in front of the workpiece conveying direction, and the lower blocking mechanism includes a lower blocking cylinder 305 and a lower blocking block 306, and the lower blocking cylinder 305 is used to drive the lower blocking block 306 to move in the up-down direction, thereby blocking the workpiece from advancing. Specifically, the lower blocking mechanism has the same structure as the upper blocking mechanism. Thus, through the cooperation of the lower blocking mechanism with the lower conveying mechanism 303 and the lower lifting mechanism 304, the precise control and orderly connection of the workpiece conveying, positioning and heating processes are realized. The lower blocking mechanism is arranged in front of the workpiece conveying direction, and when the workpiece is blocked by the lower blocking block 306 during the conveying process, it indicates that the workpiece has been accurately conveyed to the designated position.
