Description

Technical Field

[0001] The utility model belongs to the technical field of solder paste printers, and more specifically, particularly relates to an auxiliary clamping device for a solder paste printer. Background Art

[0002] Modern solder paste printers are generally composed of mechanisms such as plate loading, solder paste adding, stamping, and circuit board feeding. Its working principle is: first fix the circuit board to be printed on the printing positioning table, and then the left and right scrapers of the printer print the solder paste or red glue through the steel mesh on the corresponding pads. The PCB with uniform printing is input to the placement machine through the transmission table for automatic placement.

[0003] Based on the above, the inventors have found the following problems: most of the existing solder paste printers are equipped with auxiliary clamping devices. When auxiliary clamping the PCB board, threads are usually used to fix its four corners one by one. This method fixes the PCB board more firmly, but when the PCB board is fixed, not only is the work process cumbersome, but it is also inconvenient to disassemble.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an auxiliary clamping device for a solder paste printer is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] The purpose and effect of the auxiliary clamping device of the solder paste printer of the utility model are achieved by the following specific technical means:

[0006] An auxiliary clamping device for a solder paste printer comprises a solder paste printer, a fixed cover is installed on the top of the solder paste printer, a solder paste barrel is installed on the top of the fixed cover, an opening and closing door is installed on one side of the solder paste printer, a handle is installed on the opening and closing door, a material receiving assembly is installed inside the solder paste printer, a clamping mechanism is installed on the top of the solder paste printer, a motor is installed on one side of the fixed cover, the output end of the motor is connected to a gantry via a coupling, and a scraper is installed on the top of the gantry.

[0007] Furthermore, the clamping mechanism includes a group of grooves 1 and 2 opened on the top of the solder paste printer, a bidirectional threaded rod is rotatably installed in the groove 1, a group of sliding blocks is mounted on the bidirectional threaded rod, the bidirectional threaded rod is threadedly connected to the group of sliding blocks, a motor 2 is installed on one side of the groove 1, and the output end of the motor 2 is transmission connected to the bidirectional threaded rod through a coupling.

[0008] Furthermore, a guide rod is rotatably installed in the second groove, and a clamping plate is installed on one side of a group of sliding blocks, and one end of the clamping plate is slidably connected to the guide rod.

[0011] Furthermore, a collecting box is installed inside the solder paste printer, and the inclined plate is installed on the top of the collecting box.

[0012] Furthermore, a second handle is installed on one side of the collection box.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Through the coordinated use of the bidirectional threaded rod, the sliding block, the second motor, the guide rod and the clamping plate, when the PCB board needs to be auxiliary clamped, the second motor is started, the bidirectional threaded rod rotates, and the sliding block drives the clamping plate to move relatively synchronously, and the movement of the clamping plate can be used to fix the PCB board, thereby preventing the PCB board from being offset during processing. Through the above design, the convenience and stability of clamping are improved, and the work efficiency is further improved.

[0028] Among them, the clamping mechanism includes a group of grooves 1 9 and 10 opened on the top of the solder paste printer 1, a bidirectional threaded rod 11 is rotatably installed in the groove 1 9, a group of sliding blocks 12 are mounted on the bidirectional threaded rod 11, the bidirectional threaded rod 11 is threadedly connected with the group of sliding blocks 12, a motor 2 13 is installed on one side of the groove 1 9, and the output end of the motor 2 13 is transmission-connected with the bidirectional threaded rod 11 through a coupling. Through the coordinated use of the bidirectional threaded rod 11, the sliding block 12, the motor 2 13, the guide rod 14 and the clamping plate 15, when it is necessary to auxiliary clamp the PCB board, the motor 2 13 is started, the bidirectional threaded rod 11 rotates, and the sliding block 12 drives the clamping plate 15 to move synchronously relative to each other, so that the movement of the clamping plate 15 can be used to fix the PCB board, so as to prevent the PCB board from being offset during processing. Through the above design, the convenience and stability of clamping are improved, and the work efficiency is further improved.

[0029] A guide rod 14 is rotatably installed in the second groove 10 , and a clamping plate 15 is installed on one side of a group of sliding blocks 12 , and one end of the clamping plate 15 is slidably connected to the guide rod 14 .
