[0035] 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.

[0036] See Figure 1 , Figure 2The illustrated adhesive application device is used to print adhesive onto the adhesive application area 101 of a workpiece 10. The device includes a lifting platform 11, a printing plate 21, and an adhesive application head 31. The lifting platform 11 is vertically movable, and its upper part has a bearing surface for supporting the workpiece 10, with the bearing surface facing upwards. The printing plate 21 is located above the lifting platform 11 and has a through hole 211 extending vertically through it, allowing adhesive on the upper part of the printing plate 21 to flow to the lower part. The adhesive application head 31 is located above the printing plate 21 and is positioned to abut against and move along the upper surface of the printing plate 21. When applying glue, the workpiece 10 is clamped and fixed between the printing plate 21 and the lifting platform 11 in the vertical direction. The through hole 211 corresponds to the glue application area 101 in the vertical direction. At this time, by driving the glue application head 31 to move along the upper surface of the printing plate 21, the glue located on the upper part of the printing plate 21 moves downward from the through hole 211, thereby printing the glue onto the glue application area 101 of the workpiece 10.

[0037] In some embodiments, the workpiece 10 has multiple adhesive application areas, and the printed circuit board 21 has corresponding through holes 211, thereby enabling simultaneous and precise adhesive application to multiple adhesive application areas 101, greatly improving processing efficiency. In this embodiment, the workpiece is a chip frame or substrate, see [reference]. Figure 3 As shown, it has multiple glue dispensing points arranged regularly; these glue dispensing points are the aforementioned glue application area 101. See also... Figure 12 As shown, the printing plate 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 printing plate 21 is provided with circular through holes 211, square through holes 211 and elongated through holes 211.

[0038] In this embodiment, the adhesive application device includes a cleaning component 4, which is movably disposed below the printing plate 21. Specifically, the cleaning component 4 is movably disposed below the printing plate 21 along its extension direction. During the cleaning operation, the cleaning component 4 adheres to the lower surface of the printing plate 21, and the cleaning component 4 is driven to move relative to the printing plate 21, thereby removing the adhesive or stains adhering to the lower surface of the printing plate 21.

[0039] In this embodiment, the adhesive application equipment includes a transport mechanism 5 for transporting the workpiece 10. The transport mechanism 5 is movably disposed below the printing plate 21. Specifically, the transport mechanism 5 is movably disposed along the extension direction of the printing plate 21. The cleaning component 4 is detachably connected to the transport mechanism 5. The cleaning component 4 and the transport mechanism 5 can share a single drive mechanism, that is, one of the cleaning component 4 and the transport mechanism 5 is provided with a drive mechanism for driving its movement. When the cleaning component 4 and the transport mechanism 5 are fixedly connected, the drive mechanism can drive both of them to move simultaneously. This arrangement simplifies the structure of the adhesive application equipment and saves costs.

[0040] Preferably, the conveying mechanism 5 is equipped with a drive mechanism for moving the conveying mechanism 5. Since the lower surface of the printing plate 21 does not require frequent cleaning, when cleaning of the printing plate 21 is not required, the conveying mechanism 5 is separated from the cleaning component 4. At this time, the conveying mechanism 5 alone carries the workpiece 10 under the drive mechanism. After a certain number of printing processes, when glue begins to accumulate on the bottom of the printing plate 21, the conveying mechanism 5 is fixedly connected to the cleaning component 4. At this time, under the drive mechanism, the conveying mechanism 5 can drive the cleaning component 4 to move, thereby achieving the cleaning of the lower surface of the printing plate 21.

[0041] In this embodiment, one of the cleaning component 4 and the conveying mechanism 5 is provided with an electromagnetic connector 45, and the other is provided with a mating connector 53 that can attract and connect with the electromagnetic connector 45. When the electromagnetic connector 45 is energized, it becomes magnetic, thereby connecting with the mating connector 53 and fixing the cleaning component 4 and the conveying mechanism 5 together. When the electromagnetic connector 45 is de-energized, it loses its magnetism, thereby releasing the connection between the electromagnetic connector 45 and the mating connector 53, allowing the cleaning component 4 to separate from the conveying mechanism 5. Thus, the connection and separation of the cleaning component 4 and the conveying mechanism 5 can be achieved simply by controlling the energization and de-energization of the electromagnetic connector 45.

[0042] In this embodiment, the cleaning component 4 includes a cleaning cloth (not shown in the figure) and a cleaning head 44. The cleaning head 44 is located below the cleaning cloth and is configured to move up and down. When the cleaning component 4 performs the cleaning operation, the cleaning cloth is located between the cleaning head 44 and the printing plate 21. Driven by the cleaning head 44, the cleaning cloth adheres to the lower surface of the printing plate 21. As the cleaning component 4 moves along the extension direction of the printing plate 21, the cleaning cloth cleans the lower surface of the printing plate 21.

[0043] In this embodiment, the cleaning component 4 further includes a mounting frame 41, a take-up shaft 42, and a release shaft 43. The take-up shaft 42 and the release shaft 43 are rotatably mounted on the mounting frame 41. The cleaning cloth is wound around the release shaft 43, and the free end of the cleaning cloth is connected to the take-up shaft 42. The cleaning cloth located between the take-up shaft 42 and the release shaft 43 is in a taut state. The cleaning head 44 is mounted on the mounting frame 41 and is movable up and down, and is located between the take-up shaft 42 and the release shaft 43. By controlling the take-up shaft 42 and the release shaft 43, the cleaning cloth is always kept in a taut state. By controlling the take-up shaft 42 and the release shaft 43, the cleaning cloth can also be driven to move relative to the cleaning head 44. After a period of cleaning operation, the cleaning cloth located above the cleaning head 44 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 shaft 42 and the discharge shaft 43, the cleaning cloth is moved relative to the take-up shaft 42, so that the clean cleaning cloth moves from the discharge shaft 43 to the top of the cleaning head 44, thereby improving the cleaning quality.

[0044] In some embodiments, the adhesive application device is further provided with a nozzle for applying cleaning agent to the cleaning component 4.

[0045] In this embodiment, the printing apparatus includes a support frame 200 extending along a first direction, a conveying mechanism 5 slidably connected to the support frame 200 along its length, and a cleaning component 4 slidably connected to the support frame 200 along its length. Specifically, see... Figure 2 As shown, the support frame 200 includes two that are spaced apart along a first direction, the first direction being perpendicular to the second direction. The conveying mechanism 5 is slidably disposed between the two support frames 200, and the cleaning component 4 is slidably disposed between the two support frames 200.

[0046] In some embodiments, the adhesive application device is provided with guide rails parallel to the printing plate 21, located below the printing plate 21. The conveying mechanism 5 and the cleaning component 4 are slidably connected to the guide rails. In this embodiment, the two support frames 200 are respectively provided with guide rails extending along a first direction. The sides of the conveying mechanism 5 and the cleaning component 4 are slidably connected to the two guide rails, which improves the sliding stability of the conveying mechanism 5 and the cleaning component 4 and provides guidance for their movement.

[0047] In this embodiment, see Figure 9 , Figure 10As shown, the conveying mechanism 5 includes a conveying seat 51 for conveying the workpiece 10, and a conveying frame 52. The conveying frame 52 extends along a second direction, is mounted between two support frames 200, and is slidably connected to the support frames 200 along their length. The conveying seat 51 is slidably mounted on the conveying frame 52. In this embodiment, the mounting frame 41 extends along a second direction, is mounted between two support frames 200, and is slidably connected to the support frames 200 along their length. See also... Figure 11 As shown, the mounting bracket 41 is equipped with electromagnetic connectors 45, and the electromagnetic connectors 45 include two spaced apart along the second direction, which are used to improve the stability of the connection with the conveying mechanism 5 and to improve the stability of the synchronous movement of the cleaning component 4 and the conveying mechanism 5. See also Figure 9 As shown, the transport frame 52 is provided with a mating connector 53, and there are two mating connectors 53.

[0048] In this embodiment, see Figure 10 As shown, the receiving shaft 42, the discharging shaft 43 and the cleaning head 44 extend along the second direction, and the cleaning cloth cleans the printing plate 21 as the mounting frame 41 moves along the first direction.

[0049] In this embodiment, see Figure 8 , Figure 11 As shown, the upper part of the cleaning head 44 is provided with a cleaning tank 441 with the groove opening facing upwards. The cleaning component 4 is provided with a vacuuming assembly for drawing a vacuum, which is connected to the cleaning tank 441 through a pipe. When the cleaning component 4 performs the cleaning operation, the groove opening of the cleaning tank 441 abuts against the cleaning cloth, the vacuuming assembly starts to work, and a vacuum cavity is formed between the cleaning tank 441 and the cleaning component, thereby generating a vacuum suction force to adsorb the glue and stains on the lower surface of the printing plate 21 onto the cleaning cloth.

[0050] In this embodiment, see Figure 6 , Figure 7 As shown, the transport seat 51 includes a seat body 511 and an adsorption member 512 disposed on the seat body 511. The adsorption member 512 includes a plurality of spaced adsorption members, and the lower parts of all adsorption members 512 together form an adsorption plane for adsorbing the workpiece 10.

[0051] In this embodiment, the adhesive application equipment is equipped with a first lifting mechanism 12 for driving the lifting platform 11 to move up and down. The first lifting mechanism 12 is located at the lower part of the lifting platform 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 lifting platform 11 to move up and down.

[0052] In this embodiment, the glue application equipment also includes an adjustment mechanism 13, which is connected to the lifting platform 11. The adjustment mechanism 13 is used to adjust the position of the lifting platform 11 so that the workpiece 10 on the lifting platform 11 is accurately positioned with the printing plate 21, so that after the lifting platform 11 lifts the workpiece 10 upward, the through hole 211 and the glue application area 101 are precisely aligned.

[0053] In this embodiment, the adjustment mechanism 13 is disposed at the lower part of the lifting platform 11. Specifically, the adjustment mechanism 13 is a rotating module capable of controlling the rotation of the lifting platform 11. In some embodiments, the adjustment mechanism 13 further includes a moving module capable of driving the lifting platform 11 to translate in a plane.

[0054] In this embodiment, the printing plate 21 is mounted between two support frames 200; specifically, the printing plate 21 is detachably disposed between the two support frames 200. See also Figure 2 , Figure 12 As shown, the support frame 200 has 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 printing 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 printing plate 21 to prevent it from moving. Specifically, a fixing frame 22 is fixedly provided on the outer side of the printing plate 21, and the printing plate 21 is fixed in the fixing frame 22, which is inserted into the connecting groove 210. With this configuration, when applying glue to different workpieces 10, the corresponding printing plate 21 can be replaced without changing the glue application equipment, saving costs. At the same time, the replacement operation is simple and convenient.

[0055] In this embodiment, the fixing frame 22 is a square frame, and the printing plate 21 is a square plate. In other embodiments, the fixing frame 22 and the printing 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 printing plate 21, so that both are concave in the middle, which can prevent the glue above the printing plate 21 from flowing out from the periphery.

[0056] In this embodiment, the glue application head 31 is movably mounted on the support frame 200. Specifically, see [link to relevant documentation]. Figure 2 , Figure 13As shown, the glue application equipment includes a movable frame 32, which is movably disposed above the printing plate 21. Specifically, the movable frame 32 is movable along the extension direction of the printing plate 21. In this embodiment, the movable frame 32 is slidably mounted on the support frame 200 along a first direction, and the glue application head 31 is disposed on the movable frame 32. Specifically, the glue application head 31 is movable up and down on the movable frame 32. When printing is performed, the glue application head 31 moves downward and abuts against the upper surface of the printing plate 21. Then, driven by the movable frame 32, the glue application head 31 moves relative to the printing plate 21 and performs the printing operation.

[0057] In this embodiment, a pressure sensor 33 is provided between the glue application head 31 and the moving frame 32. The glue application equipment is equipped with a lifting mechanism for driving the glue application head 31 to move up and down. The lifting mechanism is connected to the pressure sensor 33. By setting the pressure sensor 33, the pressure feedback from the glue application head 31 against the printing plate 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 glue application head 31 to move up or down, thereby adjusting the glue application head 31 and making the feedback pressure value fall within the preset range, thereby improving the printing quality.

[0058] In this embodiment, the glue application head 31 includes a squeegee 311. During the printing operation, the squeegee 311 adheres to the upper surface of the printing plate 21, and the driven moving frame 32 causes the squeegee 311 to print the glue onto the dotted area of ​​the workpiece 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 glue corrosion.

[0059] In this embodiment, the adhesive application equipment also includes a feeding mechanism 6, which provides the workpiece 10 to be adhesive-applied. The conveying seat 51 can reciprocate between the feeding mechanism 6 and the lifting platform 11. Specifically, see... Figure 4 As shown, the feeding mechanism 6 includes a hopper 61 surrounded by multiple limiting posts 611, and the workpiece 10 to be coated with adhesive is placed in the hopper 61. The feeding mechanism 6 also includes a second lifting mechanism 62, which is located below the hopper 61. The second lifting mechanism 62 includes a lifting working head that can move upward and extend into the hopper 61, thereby lifting the workpiece 10 located in the hopper 61 upward so that the transport seat 51 can pick up the workpiece from the hopper 61.

[0060] In this embodiment, see Figure 2 As shown, the feeding mechanism 6 is located on one side of the lifting platform 11 along the first direction, and the conveying seat 51 moves along the first direction after taking material from the feeding mechanism 6 to transfer the workpiece 10.

[0061] In this embodiment, the glue-applying equipment also includes a feeding mechanism 7. The feeding mechanism 7 includes a transmission channel for transporting the workpiece 10 away from the glue-applying equipment. The transport seat 51 reciprocates between the loading mechanism 6, the lifting platform 11, and the feeding mechanism 7. After the workpiece 10 has undergone glue-applying treatment, the transport seat 51 transports the workpiece 10 from the lifting platform 11 to the feeding mechanism 7 and then transmits it to the next process through the transmission channel. Specifically, see Figure 14 As shown, the unloading mechanism 7 includes a fixed track 71 and a movable track 72. The fixed track 71 and the movable track 72 are arranged parallel to each other, forming the aforementioned transmission channel. In this embodiment, the fixed track 71 is fixedly arranged, while the movable track 72 can be arranged away from or close to the fixed track 71. Thus, by changing the position of the movable track 72, the width of the transmission channel can be adjusted, thereby enabling the transmission of workpieces 10 of different sizes.

[0062] In this embodiment, the unloading mechanism 7 includes a width adjustment component 74, which drives the moving track 72 to move, thereby adjusting the width of the transmission channel. In this embodiment, both the fixed track 71 and the moving track 72 extend along the second direction. When the transport seat 51 transfers the workpiece 10, there is no need to rotate the workpiece 10; it can be transported along the first and second directions.

[0063] In this embodiment, see Figure 15 As shown, the unloading mechanism 7 includes a clamping member 73, which clamps the workpiece 10. The workpiece 10 is then driven to move by moving the clamping member 73, thereby allowing the workpiece 10 to be transported along the conveying channel. In this embodiment, the clamping member 73 is driven by a clamping cylinder to achieve the clamping operation. In some embodiments, the unloading mechanism 7 is provided with a pushing member, which pushes the workpiece 10 to move.

[0064] In this embodiment, the glue application equipment is also equipped with a waste box 8, which is arranged adjacent to the feeding mechanism 6. For unqualified workpieces 10, they can be transported to the waste box 8.

[0065] In this embodiment, see Figure 1 As shown, the glue application equipment includes a housing 100, and a monitor 110 for human-machine interaction is provided on the housing 100 for operators to monitor the glue application equipment or issue task instructions to the glue application equipment.

[0066] In this embodiment, the housing 100 is also provided with a cleaning agent inlet 120 and a liquid level display 130. Cleaning agent is added through the cleaning agent inlet 120 to provide cleaning agent to the cleaning component 4, and the remaining amount of cleaning agent is displayed through the liquid level display 130. The housing 100 is also provided with an inspection door 140. When the adhesive application equipment is working, the inspection door 140 is in a closed state. When the adhesive application equipment is being inspected or repaired, the inspection door 140 can be opened. The housing 100 is also provided with a warning light column 150 for providing alarm signals and a cooling fan 170 for dissipating heat from the adhesive application equipment. Meanwhile, a discharge port 160 is provided on one side of the housing 100, located on one side of the transmission channel of the unloading mechanism 7, for unloading the workpiece 10 that has undergone adhesive application.

[0067] In this embodiment, the glue application equipment is further equipped with a detection module for positioning the workpiece 10 on the lifting platform 11. The detection module is signal-connected to the adjustment mechanism 13. The detection module is used to position the workpiece on the lifting platform 11 so that the adjustment mechanism 13 can adjust the position of the workpiece 10 and ensure that the workpiece 10 on the lifting platform 11 is accurately positioned with the printing plate 21. This ensures that the through hole 211 of the printing plate 21 is accurately aligned with the glue application area 101 on the workpiece 10 during the glue application operation, improving the glue application quality. In this embodiment, the detection module is integrated into the conveying mechanism 5. Specifically, the detection module is connected to the conveying seat 51, simplifying the structure of the glue application equipment. After the conveying seat 51 moves the workpiece 10 onto the lifting platform 11, it only needs a short stroke to move the detection module above the lifting platform 11, thereby enabling the detection work and improving the working efficiency of the glue application equipment.

[0068] In summary, the glue-applying equipment of this embodiment uses a printing plate 21 and a glue-applying head 31 to apply glue to the workpiece. During the glue-applying process, the lower surface of the printing plate 21 abuts against the workpiece 10, thereby fixing the workpiece 10 and positioning it relative to the printing plate 21. The glue-applying equipment is equipped with a cleaning component 4. When the lower surface of the printing plate 21 becomes coated with glue or becomes stained due to repeated applications, the cleaning component 4 abuts against the lower surface of the printing plate 21 and moves relative to the printing plate 21 to remove the glue or stains adhering to the lower surface of the printing plate 21. This ensures the normal operation of the printing equipment and guarantees printing quality.
