Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, specifically to a PCB board adhesive coating device. Background Technology

[0002] Modern solder paste printing machines generally consist of mechanisms for mounting the printing plate, applying solder paste, printing, and conveying the circuit board. Its working principle is as follows: First, the circuit board to be printed is fixed on the printing positioning table. Then, the left and right squeegees of the printing machine apply solder paste or red glue through the holes in the stencil to the corresponding positions on the circuit board. Finally, it is fed to the placement machine via a conveyor for automatic placement.

[0003] Currently, the existing utility model with publication number CN219564453U discloses a solder paste printing machine, including a fixed frame and a support frame. The support frame is provided on the inner side of the fixed frame, and the support frame and the fixed frame are fixedly connected. The inner side of the support frame is provided with a placement groove, and the inner wall of the support frame is provided with a sliding groove. A first slider is provided inside the sliding groove, and the first slider is slidably connected to the sliding groove. A first distance sensor is embedded on the top of the first slider. A screen is provided on one side of the top of the support frame, and the screen is fixedly connected to the support frame. A second distance sensor is provided on the top of the support frame.

[0004] In the above solution, the existing screen is fixed on the support frame, and the position of the placement slot is difficult to adjust. This makes it difficult to accurately place the PCB board in the required position when printing the PCB board, which can easily lead to the red glue not being printed in the required position. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a PCB board gluing device. By providing a stencil adjustment component and adjustment mechanism, the holes of the stencil can be precisely matched with the PCB board, solving the problem that the prior art is difficult to accurately place the PCB board in the required position, thereby allowing red glue to be printed in the required position.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A PCB board adhesive coating device includes a body, a first lifting device mounted on the upper end of the body, a moving device mounted on the lifting end of the first lifting device, a second lifting device mounted on the moving end of the moving device, a scraper frame mounted on the lifting end of the second lifting device, a stencil adjustment assembly provided on the side wall of the moving device, a stencil adjustment assembly containing a stencil, a mounting frame fixed on the upper end of the body, an adjustment mechanism provided within the mounting frame, and a placement frame provided on the adjustment mechanism.

[0008] When red glue needs to be printed onto a PCB board, the PCB board is fixed to the top of the placement rack. Then, the stencil is installed in the stencil adjustment assembly, and its position is adjusted so that the holes in the stencil initially align with the PCB board. Next, the adjustment mechanism is activated to adjust the position of the placement rack, ensuring a precise alignment between the stencil holes and the PCB board. Red glue is poured onto the stencil, and the first lifting device is activated, causing the moving device to move downwards. This downward movement of the moving device moves the stencil adjustment assembly downwards, which in turn moves the stencil downwards, bringing it against the top of the PCB board. Then, the second lifting device is activated, causing the squeegee holder to move downwards, bringing it against the top of the stencil. Finally, the moving device is activated, moving the second lifting device, which in turn moves the squeegee holder, thus printing the red glue onto the top of the PCB board.

[0009] By incorporating a stencil adjustment assembly and mechanism, the holes in the stencil can be precisely aligned with the PCB board, solving the problem of existing technologies making it difficult to accurately place the PCB board in the required position, thus allowing red glue to be printed in the desired location.

[0010] The utility model is further configured such that: the steel mesh adjustment assembly includes two adjustment frames symmetrically fixed on the side wall of the mobile device, the side wall of the adjustment frame is formed with a slot, and the upper end of the adjustment frame is screwed with multiple screws.

[0011] With the above technical solution, when it is necessary to install the stencil, insert both ends of the stencil into the two slots respectively, then move the stencil so that the holes of the stencil initially match the PCB board, and then rotate multiple screws so that the screws press against the upper end of the stencil, thereby fixing the stencil in the required position.

[0012] The utility model is further configured such that: the adjustment mechanism includes a front-to-back adjustment component and a left-to-right adjustment component, each of the front-to-back adjustment component and the left-to-right adjustment component is provided with a set of drive components, the front-to-back adjustment component includes a slide rod and a first threaded rod provided on the left-to-right adjustment component, two sliding blocks cooperating with the slide rod are symmetrically fixed at the lower end of the placement frame, two first moving blocks screwed to the first threaded rod are symmetrically fixed at the lower end of the placement frame, and the end of the first threaded rod is provided on one of the sets of drive components.

[0013] With the above technical solution, when it is necessary to move the placement rack back and forth, one of the drive components is activated to drive the first threaded rod to rotate. The rotation of the first threaded rod drives the first moving block to move back and forth, thereby driving the placement rack to move back and forth.

[0014] The utility model is further configured such that: the left and right moving component includes two slide rails fixed on the inner wall of the mounting frame, multiple sliders are slidably connected on the slide rails, the two ends of the slide rod are respectively fixed on the side walls of two of the sliders, one end of the first threaded rod is rotatably connected to the side wall of one of the sliders, a second threaded rod is provided on one of the drive components, and a second moving block that is screwed to the second threaded rod is fixed at the lower end of the placement frame.

[0015] With the above technical solution, when it is necessary to move the placement rack left or right, one of the drive components is activated to drive the second threaded rod to rotate. The rotation of the second threaded rod drives the second moving block to move left or right, thereby driving the placement rack to move left or right.

[0016] The utility model is further configured such that: the drive assembly includes an adjustment knob rotatably connected to the side wall of the mounting bracket, a first gear is fixed on the extension end of the adjustment knob through the mounting bracket, a first connecting rod is rotatably connected to the side wall of the first gear, a second gear meshing with the first gear is rotatably connected to the side wall of the first connecting rod, a second connecting rod is rotatably connected to the side wall of the second gear, a third gear meshing with the second gear is rotatably connected to the side wall of the second connecting rod, and a first threaded rod and a second threaded rod are respectively fixed on the third gears of the two sets of drive assemblies.

[0017] With the above technical solution, when it is necessary to drive the first threaded rod or the second threaded rod to rotate, the adjustment knob is driven to rotate. The rotation of the adjustment knob drives the first gear to rotate, the rotation of the first gear drives the second gear to rotate, and the rotation of the second gear drives the third gear to rotate, thereby driving the first threaded rod or the second threaded rod to rotate.

[0018] The beneficial effects of this utility model are:

[0019] Compared with existing technologies, by incorporating a stencil adjustment component and adjustment mechanism, the holes of the stencil can be precisely aligned with the PCB board, solving the problem that existing technologies struggle to accurately place the PCB board in the required position, thus allowing red glue to be printed in the desired location.

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] The following is for reference Figures 1 to 4 This utility model will now be described.

[0027] A PCB board adhesive coating device includes a body 1, a first lifting device 2 installed on the upper end of the body 1, a moving device 3 installed on the lifting end of the first lifting device 2, a second lifting device 4 installed on the moving end of the moving device 3, a scraper frame 5 installed on the lifting end of the second lifting device 4, a steel mesh adjustment component provided on the side wall of the moving device 3, a steel mesh 6 provided inside the steel mesh adjustment component, a mounting frame 7 fixed on the upper end of the body 1, an adjustment mechanism provided inside the mounting frame 7, and a placement frame 8 provided on the adjustment mechanism.

[0028] When red glue needs to be printed on the PCB board, the PCB board is fixed on the upper end of the placement frame 8. Then, the stencil 6 is installed in the stencil adjustment assembly, and the position of the stencil 6 is adjusted so that the holes of the stencil 6 initially match the PCB board. Then, the adjustment mechanism is activated to adjust the position of the placement frame 8, so that the holes of the stencil 6 can be precisely matched with the PCB board. Red glue is poured onto the stencil 6, and the first lifting device 2 is activated, which moves the moving device 3 downward. The downward movement of the moving device 3 moves the stencil adjustment assembly downward, which moves the stencil adjustment assembly downward, which moves the stencil 6 downward, so that the stencil 6 can be pressed against the upper end of the PCB board. Then, the second lifting device 4 is activated, which moves the squeegee frame 5 downward, so that the squeegee frame 5 is pressed against the upper end of the stencil 6. Then, the moving device 3 is activated, which moves the second lifting device 4, which moves the squeegee frame 5, so that the red glue can be printed on the upper end of the PCB board.

[0029] By incorporating a stencil adjustment assembly and adjustment mechanism, the holes of the stencil 6 can be precisely aligned with the PCB board, solving the problem of existing technologies making it difficult to accurately place the PCB board in the required position, thus allowing red glue to be printed in the desired location.

[0030] The steel mesh adjustment assembly includes two adjustment frames 9 symmetrically fixed on the side wall of the moving device 3. The side wall of the adjustment frame 9 has a slot 901 formed thereon, and multiple screws 10 are screwed to the upper end of the adjustment frame 9.

[0031] When the stencil 6 needs to be installed, insert both ends of the stencil 6 into the two slots 901 respectively, then move the stencil 6 so that the holes of the stencil 6 initially match the PCB board, and then rotate the multiple screws 10 so that the multiple screws 10 press against the upper end of the stencil 6, thereby fixing the stencil 6 in the required position.

[0032] The adjustment mechanism includes a front-to-back adjustment assembly and a left-to-right adjustment assembly. Each of the front-to-back adjustment assembly and the left-to-right adjustment assembly is provided with a set of drive components. The front-to-back adjustment assembly includes a slide rod 11 and a first threaded rod 12 provided on the left-to-right adjustment assembly. Two sliding blocks 13 that cooperate with the slide rod 11 are symmetrically fixed at the lower end of the placement frame 8. Two first moving blocks 14 that are screwed to the first threaded rod 12 are symmetrically fixed at the lower end of the placement frame 8. The end of the first threaded rod 12 is provided on one of the drive components.

[0033] When it is necessary to move the placement rack 8 back and forth, one of the drive components is activated to drive the first threaded rod 12 to rotate. The rotation of the first threaded rod 12 drives the first moving block 14 to move back and forth, thereby driving the placement rack 8 to move back and forth.

[0034] The left and right moving component includes two slide rails 15 fixed on the inner wall of the mounting frame 7. Multiple sliders 16 are slidably connected on the slide rails 15. The two ends of the slide rod 11 are respectively fixed on the side walls of two of the sliders 16. One end of the first threaded rod 12 is rotatably connected to the side wall of one of the sliders 16. A second threaded rod 17 is provided on one of the drive components. A second moving block 18 that is screwed to the second threaded rod 17 is fixed at the lower end of the placement frame 8.

[0035] When it is necessary to move the placement rack 8 left or right, one of the drive components is activated to drive the second threaded rod 17 to rotate. The rotation of the second threaded rod 17 drives the second moving block 18 to move left or right, thereby moving the placement rack 8 left or right.

[0036] The drive assembly includes an adjustment knob 19 rotatably connected to the side wall of the mounting bracket 7. A first gear 20 is fixed to the protruding end of the adjustment knob 19 through the mounting bracket 7. A first connecting rod 21 is rotatably connected to the side wall of the first gear 20. A second gear 22 that meshes with the first gear 20 is rotatably connected to the side wall of the first connecting rod 21. A second connecting rod 23 is rotatably connected to the side wall of the second gear 22. A third gear 24 that meshes with the second gear 22 is rotatably connected to the side wall of the second connecting rod 23. A first threaded rod 12 and a second threaded rod 17 are respectively fixed to the third gear 24 of the two sets of drive assemblies.

[0037] When it is necessary to drive the first threaded rod 12 or the second threaded rod 17 to rotate, the adjusting knob 19 is rotated. The rotation of the adjusting knob 19 drives the first gear 20 to rotate, the rotation of the first gear 20 drives the second gear 22 to rotate, and the rotation of the second gear 22 drives the third gear 24 to rotate, thereby driving the first threaded rod 12 or the second threaded rod 17 to rotate.

[0038] Working principle:

[0039] When red glue needs to be printed on the PCB board, the PCB board is fixed to the upper end of the placement rack 8. Then, the two ends of the stencil 6 are respectively inserted into the two slots 901. The stencil 6 is then moved so that the holes of the stencil 6 initially match the PCB board. Then, multiple screws 10 are rotated so that they press against the upper end of the stencil 6, thus fixing the stencil 6 in the desired position. Then, the adjustment knob 19 is rotated. The rotation of the adjustment knob 19 drives the first gear 20 to rotate, which in turn drives the second gear 22 to rotate, which in turn drives the third gear 24 to rotate. This drives the first threaded rod 12 or the second threaded rod 17 to rotate. The rotation of the first threaded rod 12 drives the first moving block 14 to move back and forth, which in turn drives the placement rack 8 to move back and forth. The second threaded rod 17 rotates, causing the second moving block 18 to move left and right, which in turn causes the placement frame 8 to move left and right, so that the holes of the stencil 6 can be precisely matched with the PCB board. Then, red glue is poured onto the stencil 6, and then the first lifting device 2 is activated, causing the moving device 3 to move downward. The downward movement of the moving device 3 causes the stencil adjustment component to move downward, and the downward movement of the stencil adjustment component causes the stencil 6 to move downward, so that the stencil 6 can be pressed against the upper end of the PCB board. Then, the second lifting device 4 is activated, causing the squeegee frame 5 to move downward, so that the squeegee frame 5 is pressed against the upper end of the stencil 6. Then, the moving device 3 is activated, causing the second lifting device 4 to move, and the movement of the second lifting device 4 causes the squeegee frame 5 to move, so that the red glue can be printed on the upper end of the PCB board.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
