[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] like Figures 1 to 14 As shown, the utility model is an electrode foil matrix glue spraying device, comprising a feeding mechanism 1 and a flipping mechanism 2 arranged on a frame, wherein the feeding mechanism 1 is used to convey a lead frame 3 in a vertical state from the back to the front, and the lead frame 3 is arranged in a horizontal suspended state on the feeding mechanism 1, and the flipping mechanism 2 is arranged above the feeding mechanism 1 and is used to flip the lead frame in a vertical state on the feeding mechanism 1 upward to a horizontal state in sequence; it also includes a glue spraying placement table 4 arranged at the rear side of the flipping mechanism 2, and a glue spraying mechanism 5 arranged at the rear side of the glue spraying placement table 4, wherein the glue spraying placement table 4 is used to place the lead frame to be glued which is flipped to a horizontal state by the flipping mechanism 2; the glue spraying mechanism 5 is driven by a moving mechanism to move above the glue spraying placement table 4 and glue sprays the electrode foil 302 on the lead frame 3 in a matrix. It should be noted that matrix glue spraying refers to a plurality of dot-shaped glue spraying parts distributed in a matrix on the electrode foil, such as a 3×3 matrix distribution, a 2×3 matrix distribution, etc.

[0031] In this embodiment, the glue spraying mechanism 5 includes a glue spraying movable seat 7, on which a plurality of glue spraying heads 8 are installed and spaced from left to right and arranged side by side, and the glue outlets of the glue spraying heads 8 are located at the bottom.

[0032] In this embodiment, the moving mechanism is an existing three-dimensional moving module 6 (also called an XYZ moving module), and the glue spraying moving seat 7 is installed on the moving end of the three-dimensional moving module 6. The three-dimensional moving module 6 drives the glue spraying head 8 to move in the horizontal, vertical and vertical directions through the glue spraying moving seat 7. It should be noted that the three-dimensional moving module is an existing mature product, and its structure mainly includes a horizontal linear module, a vertical linear module and a vertical linear module. The linear modules in three directions are used together to achieve horizontal, vertical and vertical movement. Its detailed structure and working principle will not be repeated here.

[0033] In this embodiment, a pushing mechanism is provided on both the left and right sides of the glue spraying placement table 4 , and the pushing mechanism is used to push the lead frame flipped to a horizontal state by the flipping mechanism 2 backward onto the glue spraying placement table 4 .

[0034] In this embodiment, the flip mechanism 4 includes a rotating shaft 9 driven to rotate by a power assembly, and a turntable 10 is installed at the left and right ends of the rotating shaft 9, respectively. The peripheral side surface of the turntable 10 is provided with four receiving grooves 11 for accommodating the lugs 301 at the ends of the lead frame 3. The receiving grooves 11 extend in the radial direction of the turntable 10, and the four receiving grooves 11 are evenly distributed around the axis of the turntable 10. Further, the power assembly includes a flip motor 12 and a belt conveyor 13. The flip motor 12 is connected to the left end of the rotating shaft 9 through the belt conveyor 13, and the flip motor drives the rotating shaft to rotate through the belt conveyor.

[0035] like Fig.13 , 14 As shown, the feeding mechanism 1 includes a horizontally arranged material frame 101, an electric slide 102 driving the material frame 101 to move in the front-back direction, the moving direction of the electric slide is perpendicular to the rotating shaft, and a plurality of storage slots 103 for accommodating the end lugs of the lead frame are arranged at intervals on both sides of the material frame. A lifting assembly 104 is arranged below the rotating shaft, and the lifting assembly 104 is located below the material frame 101 and is used to lift the lead frame on the material frame upward to the receiving groove at the lower end of the turntable in a vertical state, so as to realize feeding; the lifting assembly includes a pair of ejector rods distributed on the left and right and having ejector grooves at the upper ends, and the ejector rods are driven to rise and fall by the lifting assembly, and the ejector rods use the ejector grooves to lift the end lugs of the lead frame upward to the receiving groove; a supporting stopper rod 14 is arranged on the lower side of the turntable 10, and after the ejector rod lifts the lead frame on the material frame to the receiving groove of the turntable, the supporting stopper rod 14 is driven by the supporting cylinder 15 to extend to the bottom of the receiving groove 11 to prevent the lead frame from falling. It should be noted that the specific structure of the flipping mechanism and the feeding mechanism is the same as that of the electrode sheet temporary storage plate storage mechanism disclosed in Chinese Patent Publication No. CN217457824U, except that the working process is opposite. In this embodiment, the lead frame on the material frame is lifted onto the turntable, and the electrode sheet temporary storage plate storage mechanism disclosed in Chinese Patent Publication No. CN217457824U is to lower the temporary storage plate (that is, the lead frame) on the turntable onto the material frame. The feeding mechanism in this embodiment and the structure and working principle of the flipping mechanism are not repeated here.

[0036] In this embodiment, the left and right ends of the rotating shaft 9 are installed on the base body 16 through bearings. The lower end of the base body 16 is provided with an arc-shaped guide surface 17. The material support stop rod 14 is slidably connected to the bottom of the base body 16 along the front-to-back direction. When the turntable 10 drives the lead frame to flip upward, the end lug of the lead frame can move along the arc-shaped guide surface, and the arc-shaped guide surface guides and supports the end lug of the lead frame.

[0037] In this embodiment, support seats 18 are fixed at the left and right ends of the glue spraying placement table 4; the pushing mechanism includes a pair of pushing blocks 19 distributed on the left and right and slidably arranged on the top of the support seat 18, and the pushing blocks 19 are arranged on the outer side of the turntable 10 located on the same side, and the inner end of the pushing block 19 is provided with a receiving groove 20 for accommodating the end lug of the lead frame. The pushing block 19 is driven by the moving component to move forward and backward to push the lead frame in the receiving groove flipped to a horizontal state backward to the glue spraying placement table 4. During operation, the pusher block 19 moves close to the turntable 10, and the receiving slot 20 on the pusher block 19 extends to the front side of the support seat 18; when the turntable 10 drives the lead frame 3 upward and then to a horizontal state, the end lugs 301 at both ends of the lead frame 3 are just received in a pair of receiving slots 20 of the pusher block 19, and then the moving assembly drives the pusher block 19 to move backward along the support seat 18, and the pusher block 19 pushes the lead frame backward and moves out of the receiving groove through the end lugs of the lead frame until it moves to the glue spraying placement table 4.

[0038] In this embodiment, the top of the glue spraying platform 4 is provided with a receiving step surface 21 for placing the lead frame, and the left and right ends of the receiving step surface 21 are provided with vertical through holes 22, and a press block 23 is slidably penetrated in the vertical through hole 22, and the upper end of the press block 23 is provided with a receiving groove 24, and the front end of the receiving groove 24 is open, and the receiving groove 24 is used to accommodate the end lug of the lead frame pushed backward by the push block 19, and the press block 23 is driven to rise and fall by a press cylinder 25 installed at the bottom of the glue spraying platform 4, so as to press the lead frame 3 onto the receiving step surface 21 of the glue spraying platform 4. Since the lugs of the lead frame are pressed by the press block, the fixing effect of the lead frame on the glue spraying platform is effectively improved, the movement of the lead frame during the glue spraying process is reduced, and the glue spraying quality is improved.

[0039] In this embodiment, the moving assembly includes a rotating shaft 26 which is horizontally installed at the lower end of the glue spraying placement table and driven to rotate by a driving motor 32. The left and right ends of the rotating shaft 26 are respectively installed with driving gears. A meshing rack 27 is provided above the driving gear. The rack 27 is longitudinally arranged and slidably cooperates with the support seat 18 located on the same side. The rack 27 is fixedly connected to the pusher block 19 located on the same side. During operation, the driving motor drives the rotating shaft to rotate, and the rotating shaft drives the driving gears at both ends to rotate. The driving gear drives the rack to move forward and backward, and the rack drives the pusher block fixedly connected thereto to move synchronously. It should be noted that during operation, the forward and backward movement of the pusher block can be realized by simply controlling the forward and reverse rotation of the driving motor.

[0040] In this embodiment, a discharge platform 28 is provided at the front side of the flip mechanism 2, and recesses 29 for making way for the two turntables 10 of the flip mechanism are provided at the left and right ends of the discharge platform 28. The flip mechanism 2 turns the electrode foil after spraying to a horizontal state and falls on the discharge platform 28. A discharge push block 31 is provided at the left end of the discharge platform 28. The discharge push block 31 is driven to move left and right by a horizontally arranged discharge cylinder 30 to push the electrode foil on the discharge platform after spraying from left to right. During operation, after spraying, the turntable turns the electrode foil after spraying 180 degrees, and the electrode foil falls on the discharge platform in a horizontal state. Then, the discharge cylinder drives the discharge push block to move from left to right, and the discharge push block pushes the electrode foil on the discharge platform to the next station.

[0041] Specific implementation process:

[0042] (1) The feeding mechanism transports multiple lead frames from the back to the front in sequence to the bottom of the flipping mechanism, and then the lifting assembly lifts the lead frame upward to the vertical receiving groove at the lower end of the turntable, and the support stopper extends to the bottom of the receiving groove to prevent the lead frame from falling; (2) The rotating shaft then drives the turntable to rotate 90 degrees counterclockwise, so that the lead frame flips upward to a horizontal state. At this time, the end lugs at both ends of the lead frame are just accommodated in the accommodating grooves of a pair of push blocks. Then the moving assembly drives the push block to move backward along the support seat. The push block pushes the lead frame backward and moves out of the receiving groove through the end lugs of the lead frame until the lead frame moves into the accommodating groove on the pressing block. The pressing block moves downward under the drive of the pressing cylinder to press the lead frame onto the glue spraying placement table. The lead frame is positioned on the receiving step surface to place it on the glue spraying table; (3) the three-dimensional moving module drives the glue spraying head to move horizontally, longitudinally and vertically through the glue spraying moving seat, and the glue spraying head sprays glue in a matrix on the electrode foil on the lead frame; (4) after the glue spraying is completed, the pressing cylinder drives the pressing block to move upward, and the pressing block drives the lead frame to move upward, so that the end lugs at both ends of the lead frame are re-located in the receiving groove of the pushing block, and then the pushing block pushes the lead frame forward and enters the receiving groove; (5) the rotating shaft drives the turntable to rotate 180 degrees counterclockwise, so that the lead frame after glue spraying falls on the unloading table in a horizontal state, and then the unloading cylinder drives the unloading push block to move from left to right, and the unloading push block pushes the electrode foil on the unloading table to the next station.

[0043] It should be noted that this embodiment adds a glue spraying mechanism, a glue spraying placement table, a corresponding material pushing mechanism, etc. on the basis of the electrode sheet temporary storage plate storage mechanism disclosed in Chinese Patent Publication No. CN217457824U, and the lead frame conveying and loading structure is the same as that of the existing patent.

[0044] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0045] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0046] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
