Description

Technical Field

[0001] This utility model relates to the field of semiconductor technology, specifically to an automated printing equipment. Background Technology

[0002] To ensure precise alignment between the printing components and the product being printed, and to guarantee print quality, existing printing equipment typically includes a detection mechanism for product positioning. Some printing equipment uses two separate stations for detection and printing to avoid interference between the two operations, increasing the overall size of the equipment. Other equipment performs both detection and printing at a single station, using a drive mechanism to move the detection mechanism to that station during detection and away afterward. However, printing equipment usually includes other components that require continuous movement, such as a loading mechanism and a transport module. Setting the detection mechanism to reciprocate increases the structural complexity and setup difficulty by requiring space for the detection mechanism's movement, further increasing the equipment's size.

[0042] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] See Figure 1 , Figure 2An automated printing apparatus is shown for printing material onto the printing area 101 of a product 10. The automated printing apparatus includes a stage 11, a screen 21, and a printing head 31. The stage 11 is vertically movable, and its upper part has a support surface for supporting the product 10, with the support surface facing upwards. The screen 21 is located above the stage 11 and has through holes 211 extending vertically through it, allowing material above the screen 21 to flow through to the bottom of the screen 21. The printing head 31 is located above the screen 21 and can rest against the upper surface of the screen 21, being movably positioned relative to the screen 21. During the printing process, the product 10 is clamped and fixed between the screen 21 and the stage 11, and the through hole 211 corresponds to the printing area 101. At this time, by driving the printing head 31 to move along the upper surface of the screen 21, the material located on the upper part of the screen 21 moves downward through the through hole 211, and the material can be printed onto the printing area 101 of the product 10.

[0044] In some embodiments, the product 10 has multiple printing areas, and the stencil 21 has correspondingly multiple through holes 211, thereby enabling simultaneous and precise printing of multiple printing areas 101, greatly improving processing efficiency. In this embodiment, the product is a chip frame or substrate, see [link to documentation]. Figure 3 As shown, it has multiple adhesive dispensing points arranged regularly; these dispensing points constitute the aforementioned printing area 101. (See also...) Figure 12 As shown, the stencil 21 is provided with a plurality of regularly arranged through holes 211. The through holes 211 can be set to different shapes according to printing requirements. In this embodiment, the stencil 21 is provided with circular through holes 211, square through holes 211 and elongated through holes 211.

[0045] In this embodiment, the automated printing equipment is provided with a first lifting mechanism 12 for driving the stage 11 to move up and down. The first lifting mechanism 12 is located at the lower part of the stage 11 to avoid interference with other mechanisms. In this embodiment, the first lifting mechanism 12 includes a lead screw module and a servo motor. In other embodiments, the first lifting mechanism 12 can adopt other components in the prior art that can drive the stage 11 to move up and down.

[0046] In this embodiment, the automated printing equipment also includes a transport module 4 for transporting the product 10, which is movably disposed below the screen 21. The automated printing equipment also includes a detection module 5, which is used to position the product 10 on the stage 11, thereby determining the position of the product 10 so that it can be adjusted to ensure accurate positioning between the product 10 on the stage 11 and the screen 21, thus improving the printing quality of the automated printing equipment. The detection module 5 is integrated into the transport module 4 and can move synchronously with it, simplifying the structure of the automated printing equipment and saving manufacturing costs. Furthermore, after the transport module 4 transports the product 10 onto the stage 11, it only needs a short stroke to move the detection module 5 above the product 10 on the stage 11, enabling detection and improving the working efficiency of the automated printing equipment.

[0047] In this embodiment, the automated printing equipment also includes an adjustment mechanism 13, which is connected to the stage 11. The adjustment mechanism 13 is used to adjust the position of the stage 11, thereby adjusting the position of the product on the stage 11. In this embodiment, the position detection module is signal-connected to the adjustment mechanism 13, so that the adjustment mechanism 13 can be guided to adjust the position of the product 10 according to the information obtained by the position detection module, so that the product 10 on the stage 11 is accurately positioned with the screen 21, so that after the stage 11 lifts the product 10 upward, the through hole 211 is precisely aligned with the printing area 101.

[0048] In this embodiment, the adjustment mechanism 13 is disposed at the lower part of the stage 11. Specifically, the adjustment mechanism 13 is a rotating module capable of controlling the rotation of the stage 11. In some embodiments, the adjustment mechanism 13 further includes a moving module capable of driving the stage 11 to translate in a plane.

[0049] In this embodiment, the detection module 5 includes an upper detection port 51 and a lower detection port 52 respectively disposed on the upper and lower sides. When the detection module 5 is in working state, see [reference needed]. Figure 10 As shown, the detection module 5 is located between the mesh plate 21 and the product 10 on the stage 11 in the vertical direction, with the upper detection port 51 facing the mesh plate 21 and the lower detection port 52 facing the product 10 on the stage 11.

[0050] In some embodiments, the automated printing equipment further includes a processing system for processing the image information obtained by the detection module 5. The detection module 5 is signal-connected to the processing system, and the processing system is signal-connected to the adjustment mechanism 13. In this embodiment, when the detection module 5 is in operation, it acquires image information of the screen 21 from the upper detection port 51 and image information of the product 10 on the stage 11 from the lower detection port 52. By analyzing this information through the processing system, the relative positional relationship between the product 10 and the screen 21 can be obtained, thereby determining the positional offset of the product 10. The positional offset information of the product 10 is then transmitted to the adjustment mechanism 13, enabling the adjustment mechanism 13 to accurately adjust the product 10.

[0051] In this embodiment, the product 10 is provided with a first positioning structure, and the lower part of the mesh plate 21 is provided with a second positioning structure. The detection module 5 is used to acquire images and obtain the relative positions of the first positioning structure and the second positioning structure, thereby analyzing the offset of the product 10. Specifically, the first positioning structure and the second positioning structure are mark marks set on the product 10 and the lower part of the mesh plate 21, which may be blind holes, labels, information codes, etc.

[0052] In this embodiment, see Figure 16 As shown, the detection module 5 also includes a camera lens 53 and a prism assembly 54. The prism assembly 54 is located between the upper detection port 51 and the lower detection port 52 in the vertical direction. The upper detection port 51, the prism assembly 54, and the camera lens 53 form a first optical path, and the lower detection port 52, the prism assembly 54, and the camera lens 53 form a second optical path. With this configuration, only one camera lens 53 is needed to obtain image information of the screen 21 through the first optical path, and at the same time, it can obtain image information of the product 10 located below through the second optical path, simplifying the structure of the detection module 5.

[0053] In some embodiments, the transport module 4 is movably disposed along the extension direction of the screen 21, and the detection module 5 is disposed on one side of the transport module 4 along the extension direction of the screen 21. In this embodiment, the automated printing equipment includes a feeding mechanism 7, which is used to provide the product 10 to be printed. The feeding mechanism 7 is disposed on one side of the stage 11 along a first direction. The transport module 4 includes a transport seat 41 and a transport frame 42. The transport frame 42 is movably disposed along the first direction. The transport seat 41 is connected to one side of the detection module 5 along the first direction. The detection module 5 or the transport seat 41 is connected to the transport frame 42. When the automated printing equipment is working, the transport seat 41 picks up the product 10 from the feeding mechanism 7. Driven by the transport frame 42, the transport seat 41 carries the product 10 to the stage 11. After the transport seat 41 transfers the product 10 onto the stage 11, the transport frame 42 only needs to move a small distance along the first direction to drive the detection module 5 to move between the screen 21 and the stage 11.

[0054] In this embodiment, the detection module 5 is connected to the transport frame 42. Specifically, the transport frame 42 extends along the second direction, and the detection module 5 is slidably connected to the transport frame 42 along its length. In this embodiment, the transport seat 41 is movable up and down and connected to the detection module 5 so that the transport seat 41 can pick up and put down the product 10 in the up and down direction.

[0055] In this embodiment, the transport seat 41 includes a seat body 411 and an adsorption member 412 disposed on the seat body 411. The adsorption member 412 includes a plurality of spaced adsorption members, and the lower parts of all adsorption members 412 together form an adsorption plane for adsorbing the product 10.

[0056] In this embodiment, see Figure 6 , Figure 7 and Figure 9 As shown, the automated printing equipment support frame 200 extends along a first direction and includes two supports spaced apart along a second direction. A transport frame 42 is disposed between the two supports 200 and is slidably disposed relative to the supports 200. Specifically, the supports 200 are provided with a first guide rail extending along the first direction, and the transport frame 42 is slidably connected to the first guide rail.

[0057] In this embodiment, the mesh panel 21 is installed between two support frames 200. Specifically, the mesh panel 21 is detachably disposed between the two support frames 200. See also Figure 2 , Figure 12As shown, the support frame 200 is provided with a connecting groove 210. The two connecting grooves 210 on the two support frames 200 are arranged with their openings facing each other. The two sides of the screen plate 21 are slidably inserted into the two connecting grooves 210 along the second direction. The support frame 200 is also provided with a clamping cylinder 220 for clamping and fixing the screen plate 21. Specifically, a fixing frame 22 is fixedly provided on the outer side of the screen plate 21, and the screen plate 21 is fixed in the fixing frame 22, which is inserted into the connecting groove 210. With this configuration, when printing different products 10, the corresponding screen plate 21 can be replaced without replacing the automated printing equipment, saving costs. At the same time, the replacement operation is simple and convenient.

[0058] In this embodiment, the fixing frame 22 is a square frame and the mesh plate 21 is a square plate. In other embodiments, the fixing frame 22 and the mesh plate 21 may be other shapes. In this embodiment, the upper surface of the fixing frame 22 is higher than the upper surface of the mesh plate 21, so that both are concave in the middle, which can prevent the material above the mesh plate 21 from flowing out from the periphery.

[0059] In this embodiment, the printing head 31 is movably mounted on the support frame 200. Specifically, the automated printing equipment includes a movable frame 32, which is movably mounted above the screen 21. Specifically, the movable frame 32 is movably mounted along the extending direction of the screen 21, and the printing head 31 is mounted on the movable frame 32. See also... Figure 2 , Figure 13 As shown, the movable frame 32 is mounted on the support frame 200 and can be movably set along the first direction. The movable frame 32 drives the printing head 31 to move, thereby completing the printing operation.

[0060] In this embodiment, the printing head 31 is mounted on the movable frame 32 and is capable of moving up and down. A pressure sensor 33 is provided between the printing head 31 and the movable frame 32. The automated printing equipment is equipped with a lifting mechanism for driving the printing head 31 to move up and down. The pressure sensor 33 is signal-connected to the lifting mechanism. By setting the pressure sensor 33, the pressure feedback from the printing head 31 against the screen 21 can be obtained, and the pressure value can be monitored in real time. When the pressure value is not within the preset range, such as too high or too low pressure, the lifting mechanism can be controlled in time to control the printing head 31 to move up or down, thereby adjusting the printing head 31 and making the feedback pressure value fall within the preset range, thereby improving the printing quality.

[0061] In this embodiment, the printing head 31 includes a squeegee 311. During the printing operation, the squeegee 311 adheres to the upper surface of the screen 21, and the driven moving frame 32 causes the squeegee 311 to print adhesive onto the dispensing area of ​​the product 10. In this embodiment, the squeegee 311 is made of stainless steel, which gives the squeegee 311 a long service life and makes it less susceptible to corrosion from adhesives and other materials.

[0062] In this embodiment, the automated printing equipment includes a cleaning component 6, which is movably disposed below the screen 21. Specifically, the cleaning component 6 is movable along the extension direction of the screen 21. During the cleaning operation, the cleaning component 6 abuts against the lower surface of the screen 21, and the lower surface of the screen 21 is cleaned by driving the cleaning component 6 to move.

[0063] In this embodiment, the cleaning component 6 and the transport module 4 are detachably connected. Since the lower surface of the screen 21 does not require frequent cleaning, when cleaning is needed, the transport module 4 is fixedly connected to the cleaning component 6, and the transport module 4 drives the cleaning component 6 to move, thereby performing the cleaning operation. When cleaning of the screen 21 is not required, the transport module 4 is separated from the cleaning component 6, and the transport module 4 performs the transport operation independently. This configuration eliminates the need for a separate drive mechanism for the cleaning component 6, thereby simplifying the structure of the automated printing equipment and saving costs.

[0064] In this embodiment, one of the cleaning component 6 and the transport module 4 is provided with an electromagnetic connector 611, and the other is provided with a mating connector 421 that attracts and connects to the electromagnetic connector 611. When the electromagnetic connector 611 is energized, it becomes magnetic, thereby connecting with the mating connector 421 and fixing the cleaning component 6 and the transport module 4 together. When the electromagnetic connector 611 is de-energized, it loses its magnetism, thereby releasing the connection between the electromagnetic connector 611 and the mating connector 421, allowing the cleaning component 6 to separate from the transport module 4. Thus, the connection and separation of the cleaning component 6 and the transport module 4 can be achieved simply by controlling the energization and de-energization of the electromagnetic connector 611.

[0065] In this embodiment, the cleaning component 6 includes a cleaning cloth (not shown in the figure) and a cleaning head 64. The cleaning head 64 is located below the cleaning cloth and is configured to move up and down. When the cleaning component 6 performs the cleaning operation, the cleaning cloth is located between the cleaning head 64 and the mesh plate 21. Driven by the cleaning head 64, the cleaning cloth abuts against the lower surface of the mesh plate 21. As the cleaning component 6 moves along the extension direction of the mesh plate 21, the cleaning cloth cleans the lower surface of the mesh plate 21.

[0066] In this embodiment, the cleaning component 6 further includes a mounting frame 61, a take-up roller 62, and a release roller 63. The take-up roller 62 and the release roller 63 are rotatably mounted on the mounting frame 61, and the cleaning cloth is tensioned between the take-up roller 62 and the release roller 63. Specifically, the cleaning cloth is wound around the release roller 63, and the free end of the cleaning cloth is connected to the take-up roller 62. The cleaning cloth located between the take-up roller 62 and the release roller 63 is in a tensioned state. The cleaning head 64 is mounted on the mounting frame 61 and is movable up and down, and is located between the take-up roller 62 and the release roller 63. By controlling the take-up roller 62 and the release roller 63, the cleaning cloth is always kept in a tensioned state. By controlling the take-up roller 62 and the release roller 63, the cleaning cloth can also be driven to move relative to the cleaning head 64. After a period of cleaning operation, the cleaning cloth located above the cleaning head 64 will be covered with glue or stains. If this section of the cleaning cloth is still used for cleaning, the cleaning effect will be greatly reduced. Therefore, by using the take-up roller 62 and the feed roller 63, the cleaning cloth is moved relative to the take-up roller 62, so that the clean cleaning cloth moves from the feed roller 63 to the top of the cleaning head 64, thereby improving the cleaning quality.

[0067] In some embodiments, the adhesive application device is further provided with a nozzle for providing cleaning agent to the cleaning component 6.

[0068] In this embodiment, the cleaning component 6 is slidably connected to the support frame 200 along the length of the support frame 200. See also Figure 6 , Figure 9 As shown, the cleaning component 6 is slidably disposed between the two support frames 200. Specifically, the cleaning component 6 is also slidably connected to the first guide rail. When the transport module 4 is fixedly connected to the cleaning component 6, the transport module 4 drives the cleaning component 6 to slide along the first guide rail.

[0069] Specifically, the mounting bracket 61 extends along the second direction, is mounted between two support brackets 200, and is slidably connected to the support brackets 200 along their length. See also Figure 11 As shown, the mounting bracket 61 is equipped with electromagnetic connectors 611, and the electromagnetic connectors 611 include two spaced apart along the second direction, which are used to improve the stability of the connection with the transport module 4 and to improve the stability of the synchronous movement of the cleaning component 6 and the transport module 4. See also Figure 9 As shown, the transport frame 42 is provided with mating connectors 421, and two mating connectors 421 are correspondingly provided. In this embodiment, see... Figure 11 As shown, the receiving roller 62, the discharging roller 63 and the cleaning head 64 extend along the second direction, and the cleaning cloth cleans the mesh plate 21 as the mounting frame 61 moves along the first direction.

[0070] In this embodiment, see Figure 11As shown, the upper part of the cleaning head 64 is provided with a cleaning tank 641 with the groove opening facing upwards. The cleaning component 6 is provided with a vacuuming assembly for drawing a vacuum, which is connected to the cleaning tank 641 through a pipe. When the cleaning component 6 performs the cleaning operation, the groove opening of the cleaning tank 641 abuts against the cleaning cloth, and the vacuuming assembly starts to work, so that a vacuum cavity is formed between the cleaning tank 641 and the cleaning cloth, thereby generating a vacuum suction force to adsorb the glue and stains on the lower surface of the mesh plate 21 onto the cleaning cloth.

[0071] In this embodiment, the feeding mechanism 7 includes a feeding bin 71 surrounded by multiple limiting posts 711, and the product 10 to be printed is placed in the feeding bin 71. The feeding mechanism 7 also includes a second lifting mechanism 72, which is located below the feeding bin 71. The second lifting mechanism 72 includes a lifting working head that can move upward and extend into the feeding bin 71, thereby lifting the product 10 located in the feeding bin 71 upward so that the conveying module 4 can pick up the product from the feeding bin 71.

[0072] In this embodiment, the automated printing equipment is also equipped with a waste bin 8, which is arranged adjacent to the feeding mechanism 7. For unqualified products 10, they can be transported to the waste bin 8.

[0073] In this embodiment, the automated printing equipment also includes a feeding mechanism 9. The feeding mechanism 9 includes a transfer channel for transferring the product 10 out of the automated printing equipment. The handling module 4 reciprocates between the loading mechanism 7, the platform 11, and the feeding mechanism 9. After the product 10 has completed the printing process, the handling module 4 transfers the product 10 from the platform 11 to the feeding mechanism 9 and then transfers it to the next process through the transfer channel. Specifically, see [link to documentation]. Figure 14 As shown, the feeding mechanism 9 includes a fixed track 91 and a moving track 92. The fixed track 91 and the moving track 92 are arranged parallel to each other, forming the aforementioned transmission channel. In this embodiment, the fixed track 91 is fixedly arranged, while the moving track 92 can be arranged away from or close to the fixed track 91. Thus, by changing the position of the moving track 92, the width of the transmission channel can be adjusted, thereby enabling the transmission of products 10 of different sizes.

[0074] In this embodiment, the unloading mechanism 9 includes a width adjustment component 94, which drives the moving track 92 to move, thereby adjusting the width of the transmission channel. Specifically, the width adjustment component 94 consists of a lead screw and a nut. In this embodiment, both the fixed track 91 and the moving track 92 extend along the second direction. When the transport module 4 transfers the product 10, it is not necessary to rotate the product 10; it can be transported simply along the first and second directions.

[0075] In this embodiment, see Figure 15As shown, the unloading mechanism 9 includes a clamping member 93, which clamps the product 10. The product 10 is then driven to move by moving the clamping member 93, thereby allowing the product 10 to be transported along the transmission channel. In this embodiment, the clamping member 93 is driven by a clamping cylinder to achieve the clamping operation. In some embodiments, the unloading mechanism 9 is provided with a pushing member, which pushes the product 10 to move.

[0076] The workflow of the automated printing equipment is as follows: (1) Place the product 10 on the stage 11 located below the screen 21; (2) The detection module 5 detects and positions the product 10 located on the stage 11; (3) The detection module 5 transmits the obtained position information of the product 10 to the adjustment mechanism 13, and the adjustment mechanism 13 adjusts the position of the stage 11 according to the obtained position information, thereby realizing the position adjustment of the product 10; (4) The stage 11 moves upward and lifts the product 10 upward, so that the product 10 abuts against the lower surface of the screen 21, and the through hole 211 on the screen 21 corresponds to the printing area 101 on the product 10; (5) The printing head 31 abuts against the upper surface of the screen 21 and moves along the upper surface of the screen 21, so that the material is printed from the through hole 211 on the screen 21 onto the printing area 101 of the product 10.

[0077] Specifically, in step (2) above, the detection module 5 moves between the mesh plate 21 and the product 10 and acquires image information on the upper and lower sides. The processing system analyzes and processes the image information and determines the positional offset of the product 10 relative to the mesh plate 21.

[0078] In this embodiment, see Figure 1 As shown, the automated printing equipment includes a housing 100, on which a monitor 110 for human-machine interaction is installed, for operators to monitor or perform operations on the automated printing equipment.

[0079] The housing 100 is also equipped with a cleaning agent inlet 120 and a liquid level display 130. Cleaning agent is added through the inlet 120 to supply cleaning agent to the cleaning components 6, and the remaining amount of cleaning agent is displayed on the liquid level display 130. The housing 100 also has an inspection door 140. When the automated printing equipment is operating, the inspection door 140 is closed. When inspecting or maintaining the automated printing equipment, the inspection door 140 can be opened. The housing 100 also has an alarm light column 150 for providing alarm signals and a cooling fan 170 for dissipating heat from the automated printing equipment. Additionally, a discharge port 160 is located on one side of the housing 100, situated on one side of the conveying channel of the unloading mechanism 9, for unloading products that have completed printing.

[0080] In summary, the automated printing equipment of this embodiment places the product 10 on the stage 11, drives the stage 11 upward to clamp the product 10 between the screen 21 and the stage 11, thus fixing the product 10. Then, the printing head 31 prints the material from the through-holes 211 of the screen 21 onto the printing area 101 of the product 10. The automated printing equipment is equipped with a detection module 5 for positioning the product 10, ensuring that the product 10 can be accurately positioned with the screen 21. This ensures that when the product 10 is clamped between the screen 21 and the stage 11, the through-holes 211 on the screen 21 are accurately aligned with the printing area 101 on the product 10, guaranteeing printing quality. The detection module 5 is integrated with the transport module 4 for transporting the product 10. This simplifies the structure of the automated printing equipment. After the transport module 4 transports the product 10 onto the platform 11, the transport module 4 drives the detection module 5 to move a small distance, allowing the detection module 5 to reach its working position, thus improving the efficiency of the automated printing equipment.
