[0045] like Figure 1 and Figure 2 As shown, a Cartesian coordinate system is established, defining the length direction of the glue spraying device 1000 as parallel to the direction indicated by the x-axis, the width direction of the glue spraying device 1000 as parallel to the direction indicated by the y-axis, and the height direction of the glue spraying device 1000 as parallel to the direction indicated by the z-axis. It should be understood that the above definitions are merely for facilitating the understanding of the relative positional relationships of the various components of the glue spraying device 1000 and should not be construed as limiting the present application.

[0046] In an embodiment, a glue spraying device 1000 is provided, which can be used to provide a glue spraying function during the processing of a workpiece 2000 such as a power semiconductor device.

[0047] like Figure 1 and Figure 2 As shown, the glue spraying device 1000 includes a carrier 100 , a slide rail 200 , a first driving mechanism 300 and a spray head 500 .

[0048] The carrier 100 can be used to carry a workpiece 2000 to be sprayed with glue. The workpiece 2000 can have a first surface 2100 and a second surface 2200 disposed opposite to each other. In some embodiments, the carrier 100 can have a hollow hole 110.

[0049] During the glue spraying process, the workpiece 2000 can be placed on the carrier 100, and the edge of the workpiece 2000 can be supported by the carrier 100. In addition, the first surface 2100 of the workpiece 2000 can be positioned away from the carrier 100. The second surface 2200 of the workpiece 2000 can face one side of the carrier 100, and most of the second surface 2200 can be exposed through the hollow hole 110.

[0050] In other embodiments, during the glue spraying process, the workpiece 2000 may also be mounted on the carrier 100 via a jig.

[0051] In some embodiments, the slide rail 200 can be fixedly mounted on the carrier 100. Furthermore, the slide rail 200 can be disposed through the carrier 100 and extend from a side of the carrier 100 facing the first surface 2100 of the workpiece 2000 to a side of the carrier 100 facing away from the first surface 2100 of the workpiece 2000. A through hole 120 can be defined in the carrier 100 for the slide rail 200 to pass through.

[0052] In other embodiments, the slide rail 200 may also be fixedly disposed on one side of the supporting frame 100 .

[0053] like Figure 1 and Figure 2 As shown, the nozzle 500 can be movably disposed relative to the slide rail 200 and is in transmission connection with the first drive mechanism 300. The first drive mechanism 300 can be configured to drive the nozzle 500 to move along the slide rail 200. In an embodiment, the through hole 120 on the carrier 100 is sized to allow the nozzle 500 and other movable structures to pass smoothly through. In addition, the nozzle 500 can include a first state position 3101 and a second state position 3102 disposed along the slide rail 200. The first state position 3101 and the second state position 3102 can be located at opposite ends of the slide rail 200. When the nozzle 500 is in the first state position 3101, the nozzle 500 can be opposite the first surface 2100 of the workpiece 2000. When the nozzle 500 is in the second state position 3102, the nozzle 500 can be opposite the second surface 2200 of the workpiece 2000.

[0054] During glue spraying on a workpiece 2000, the workpiece 2000 can be placed on the carrier 100, and the first drive mechanism 300 drives the spray head 500 to move along the slide rail 200. When the spray head 500 moves to the first position 3101, the spray head 500 can face the first surface 2100 of the workpiece 2000 to spray glue on the first surface 2100 of the workpiece 2000. When the first drive mechanism 300 drives the spray head 500 to move to the second position 3102, the spray head 500 can face the second surface 2200 of the workpiece 2000 to spray glue on the second surface 2200 of the workpiece 2000. That is, the first surface 2100 and the second surface 2200 of the workpiece 2000, which are opposite to each other, can both be sprayed with glue, so that the glue has a wider coverage area on the workpiece 2000, thereby improving the bonding strength between the chip and other structures in the workpiece 2000, reducing the probability of water vapor intrusion into the workpiece 2000, and extending the service life of the workpiece 2000.

[0055] like Figures 2 to 3 As shown, in some embodiments, the slide rail 200 may be semicircular, and the center of the semicircular arc where the slide rail 200 is located may be approximately located at the position where the workpiece 2000 is placed on the carrier 100. After the workpiece 2000 is placed on the carrier 100, one end of the slide rail 200 may face the first surface 2100 of the workpiece 2000, and the other end of the slide rail 200 may face the second surface 2200 of the workpiece 2000.

[0056] In other embodiments, the slide rail 200 may be a linear slide rail and may extend in a direction parallel to the thickness direction of the workpiece 2000. The thickness direction of the workpiece 2000 may refer to a direction parallel to the first surface 2100 and pointing toward the second surface 2200. The thickness direction of the workpiece 2000 may also be parallel to the height direction of the adhesive spraying device 1000.

[0057] In some embodiments, the slide rail 200 may include an integral main plate 210 and two side plates 220. Both the main plate 210 and the side plates 220 may have an arc-shaped plate structure. The two side plates 220 may be disposed on opposite sides of the main plate 210 and protrude from the same side of the main plate 210. Accordingly, the main plate 210 and the two side plates 220 may cooperate to form a U-shaped groove 230.

[0058] In some embodiments, the slide rail 200 may be configured with two sets of oppositely disposed slide grooves 240. The two sets of oppositely disposed slide grooves 240 may be disposed one-to-one on the opposite sides of the two side panels 220. In some embodiments, each set of slide grooves 240 may include two slide grooves 240, which are arranged side by side. Both slide grooves 240 extend along the extension direction of the slide rail 200 and extend from one end of the slide rail 200 to the other end. In other words, the slide grooves 240 may be semicircular grooves.

[0059] In other embodiments, each group of slide grooves 240 may also include one, three, or any other number of slide grooves 240 .

[0060] like Figure 2 and Figure 3 As shown, the first drive mechanism 300 may include two groups of rolling elements 310 disposed opposite to each other, two first drive elements 320, and a bracket 330. Each group of rolling elements 310 may include two rolling elements 310, that is, the number of rolling elements 310 disposed in each group may be consistent with the number of rolling elements 310 disposed in each group of chutes 240. The rolling elements 310 may be roller structures. In an embodiment, the two groups of rolling elements 310 may be rollingly disposed in the two groups of chutes 240 in a one-to-one correspondence, that is, one rolling element 310 is rollingly installed in each chute 240. In some embodiments, the axial direction of the rolling element 310 may be parallel to the width direction of the glue spraying device 1000, and the rolling axis of the rolling element 310 may be parallel to the axial direction of the rolling element 310.

[0061] In some embodiments, a first U-shaped support portion 331 may be configured on one side of the bracket 330. The opening of the first U-shaped support portion 331 may face one side of the U-shaped groove 230. Two first driving members 320 may be mounted on the two sidewalls of the first U-shaped support portion 331 in a one-to-one correspondence, with the two first driving members 320 disposed opposite each other. In this embodiment, one of the first driving members 320 may be drivingly connected to a set of two rolling members 310. The other first driving member 320 may be drivingly connected to another set of two rolling members 310.

[0062] like Figure 2 and Figure 3As shown, in some embodiments, the output shaft of the first driving member 320 can be fixedly connected to a first gear 341. The end of the rolling member 310 facing the first driving member 320 to which it is connected can be fixedly connected to a rotating shaft 343. The rotating shaft 343 can be rotatably connected to the side wall of the first U-shaped support portion 331 at a corresponding position. A second gear 342 is fixedly connected to the rotating shaft 343, and the second gear 342 can be meshed with the first gear 341. Thus, a transmission connection can be achieved between the first driving member 320 and the rolling member 310. That is, a transmission connection is achieved between the first driving member 320 and the two rolling members 310 to which it is connected via a gear train. In some embodiments, the axial direction of the rotating shaft 343 can be parallel to the width direction of the glue spraying device 1000.

[0063] In other embodiments, the first driving member 320 and the two rolling members 310 connected thereto may be connected via a synchronous belt and a synchronous wheel, or via a pulley and a belt.

[0064] like Figures 2 to 4 As shown, in some embodiments, the rolling element 310 may be provided with meshing teeth 311, and the meshing teeth 311 may be arranged around the circumference of the rolling element 310. Rack portions 251 may be provided on both opposing sidewalls of the slideway 240. The rack portions 251 may extend along the extension direction of the slide rail 200 and may extend from one end to the other end of the slide rail 200. In this embodiment, the two rack portions 251 are disposed opposite each other and are both meshed with the meshing teeth 311 on the rolling element 310.

[0065] During operation, the first driving member 320 can drive the rolling member 310 to rotate. During the rotation of the rolling member 310, the rolling member 310 can move along the rack portion 251, that is, move along the slide rail 200. In this embodiment, the nozzle 500 can be mounted on the bracket 330, so that the first driving mechanism 300 can drive the nozzle 500 to move relative to the slide rail 200, that is, the nozzle 500 can be slidably mounted on the slide rail 200.

[0066] like Figure 2 and Figure 3 As shown, in some embodiments, a first stopper 312 is further configured on the circumference of the rolling element 310. A second stopper 252 is further configured on the inner wall of the chute 240 facing the rolling element 310. The first stopper 312 can be plugged into the second stopper 252. The first stopper 312 can cooperate with the second stopper 252 to restrict the rolling element 310 from escaping from the chute 240 in the axial direction of the rolling element 310. This prevents the rolling element 310 from escaping from the chute 240 at will, thereby ensuring that the first drive mechanism 300 smoothly drives the nozzle 500 to move along the slide rail 200.

[0067] In some embodiments, the first limiting portion 312 can be a limiting groove provided on the circumference of the rolling element 310, and the limiting groove can be provided around the circumference of the rolling element 310, that is, the limiting groove is an annular groove. The second limiting portion 252 can be a limiting ridge protruding from the slide groove 240, and the limiting ridge can extend from one end of the slide rail 200 to the other end along the extension direction of the slide rail 200. In an embodiment, both opposite side walls of the slide groove 240 can be provided with protruding phase ridges. Both opposite limiting ridges can be inserted into the limiting groove on the circumference of the rolling element 310 to achieve axial limitation of the rolling element 310, preventing the rolling element 310 from arbitrarily escaping from the slide groove 240, and thus preventing the first driving mechanism 300 from arbitrarily escaping from the slide rail 200.

[0068] In other embodiments, the first limiting portion 312 may also be a limiting ridge protruding from the circumference of the rolling element 310 . The second limiting portion 252 may also be a limiting groove formed on the inner wall of the sliding groove 240 .

[0069] In some embodiments, two sets of rolling elements 310 disposed opposite to each other are rollingly mounted in the chute 240 on corresponding sides of the slide rail 200. In this embodiment, the two side panels 220 of the slide rail 200 can sandwich the first drive mechanism 300 therebetween and also provide axial positioning of the rolling elements 310, preventing the rolling elements 310 from arbitrarily escaping from the chute 240, thereby reducing the probability of the first drive mechanism 300 derailing.

[0070] like Figure 1 and Figure 5 As shown, in other embodiments, a slide groove 240 may be provided on the side of the slide rail 200 facing the hollow hole 110 of the carrier frame 100, and the opening of the slide groove 240 may face the side of the hollow hole 110. That is, the main plate portion 210 and the two side plate portions 220 may cooperate to form the slide groove 240. The first driving mechanism 300 may include a bracket 330, a first driving member 320 and a rolling member 310. The rolling member 310 is rollingly arranged in the slide groove 240. When the rolling member 310 is located in the middle position of the slide rail 200, the rolling axis of the rolling member 310 may be parallel to the length direction of the glue spraying device 1000, that is, the axial direction of the rolling member 310 may be parallel to the length direction of the glue spraying device 1000. The first driving member 320 may be mounted on the bracket 330 and may be transmission-connected to the rolling member 310. The rolling element 310 is provided with meshing teeth 311 on its circumferential side, and the two side plates 220 are provided with racks 251 on their opposing sides. Both racks 251 engage with the meshing teeth 311 on the circumferential side of the rolling element 310. Furthermore, the rolling element 310 is provided with a first limiting portion 312 on its circumferential side, and the two side plates 220 are provided with a second limiting portion 252 on their opposing sides. The first limiting portion 312 cooperates with the second limiting portion 252 to prevent the rolling element 310 from disengaging from the chute 240 along its axial direction.

[0071] like Figure 1 and Figure 2 As shown, the glue spraying device 1000 has a first direction M, wherein the first direction M can be perpendicular to the direction of the first state position 3101 pointing to the second state position 3102. In some embodiments, the first direction M can be parallel to the width direction of the slide rail 200, that is, the first direction M is parallel to the width direction of the glue spraying device 1000.

[0072] In the embodiment, the glue spraying device 1000 further includes a second driving mechanism 400 , which can be used to drive the spray head 500 to move along the first direction M. In some embodiments, the second driving mechanism 400 can include a second driving member 410 , a transmission rod 420 , and a sliding block 430 .

[0073] In some embodiments, the bracket 330 in the first driving mechanism 300 further includes a second U-shaped support portion 332 , and the second U-shaped support portion 332 may be disposed opposite to the first U-shaped support portion 331 .

[0074] In some embodiments, the transmission rod 420 can be a screw. The transmission rod 420 is rotatably mounted on the second U-shaped support portion 332 and can be parallel to the first direction M, that is, the transmission rod 420 can be parallel to the width of the slide rail 200. The second driving member 410 can be mounted on one end of the second U-shaped support portion 332 and be in driving connection with the transmission rod 420. In some embodiments, the second driving member 410 can be a motor.

[0075] In some embodiments, the sliding block 430 may be non-cylindrical. The sliding block 430 may be sleeved onto the transmission rod 420 and threadedly engaged with the transmission rod 420. In some embodiments, the side of the sliding block 430 facing the bottom of the groove of the second U-shaped support portion 332 may be aligned with or positioned adjacent to the second U-shaped support portion 332, thereby limiting the sliding block 430 from rotating with the transmission rod 420. The spray head 500 may be mounted on the side of the sliding block 430 facing away from the second U-shaped support portion 332.

[0076] In other embodiments, the second U-shaped support portion 332 may be further configured with a guide rail that is slidably connected to the sliding block 430 , which not only provides guidance for the sliding block 430 but also limits the sliding block 430 from rotating along with the transmission rod 420 .

[0077] In other embodiments, the second driving member 410 may also be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod. The transmission rod 420 is slidably mounted on the second U-shaped support portion 332, and the sliding direction of the transmission rod 420 is parallel to the first direction M.

[0078] During operation, the second driving member 410 can drive the transmission rod 420 to rotate. Under the action of the threaded cooperation relationship between the transmission rod 420 and the sliding block 430, the sliding block 430 can be driven to move along the axial direction of the transmission rod 420, thereby driving the nozzle 500 to move along the axial direction of the transmission rod 420, so as to realize the position adjustment of the nozzle 500 in the width direction of the spraying equipment 1000, thereby allowing the spraying range of the nozzle 500 to cover the side of the relative position of the workpiece 2000, further expanding the coverage area of ​​the glue on the workpiece 2000, improving the bonding stability of the various structures in the workpiece 2000, and also improving the airtightness inside the workpiece 2000, reducing the probability of the workpiece 2000 being invaded by water vapor, dust, etc., ensuring the normal use of the workpiece 2000, and also extending the service life of the workpiece 2000.

[0079] like Figure 1 and Figure 2 As shown, the glue spraying device 1000 may further include a robotic arm 600. One end of the robotic arm 600 may be connected to the sliding block 430, and the spray head 500 may be connected to the end of the robotic arm 600 away from the sliding block 430. Thus, the robotic arm 600 can adjust the glue spraying direction of the spray head 500 as needed, further expanding the range of motion of the spray head 500, allowing for more comprehensive glue spraying on the surface of the workpiece 2000, further improving the bonding stability of the various components of the workpiece 2000, and enhancing the airtightness of the interior of the workpiece 2000, thereby reducing the probability of moisture, dust, and the like intruding into the interior of the workpiece 2000.

[0080] In some embodiments, the robotic arm 600 may be a three-axis robotic arm, a five-axis robotic arm, or a six-axis robotic arm.

[0081] In summary, the glue spraying equipment 1000 provided in this application can realize comprehensive glue spraying on the surface of the workpiece 2000, improve the bonding strength between the various structures in the workpiece 2000, and also improve the airtightness inside the workpiece 2000, thereby reducing the possibility of the workpiece 2000 being invaded by water vapor, dust, etc., and extending the service life of the workpiece 2000.
