All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0039] like Figure 1-2 As shown, the first part of the present application proposes an assembly tool for a label printer movement, including a pressure welder, a dispensing gun, a finger cot, an antistatic wristband, a tray 1 and a roller 5. The surface of the tray 1 is provided with a first groove 11 and two second grooves 12, and the two adjacent second grooves 12 are connected through the first groove 11. Among them, the label printer movement includes a print head 2, a movement bracket 3 and a circuit board 4, one end of the print head 2 is connected to the movement bracket 3, and the other end of the print head 2 is connected to the circuit board 4; the first groove 11 is used to place the circuit board 4; the second groove 12 is used to place the print head 2 and the movement bracket 3. The pressure welder can pressure weld the circuit board 4 on the print head 2; the dispensing gun can dispense glue on the circuit board 4 and the movement bracket 3; the finger cot is used to be worn on the worker's finger; the antistatic wristband is used to be worn on the worker's wrist; the roller 5 is connected to the tray 1.

[0040] In this embodiment, the second groove 12 is adapted to the geometric dimensions of the print head 2 and the movement bracket 3, and can limit the print head 2 and the movement bracket 3; the first groove 11 is adapted to the geometric dimensions of the circuit board 4, and can limit the circuit board 4, avoiding the need to pick up the print head 2, the movement bracket 3 or the circuit board 4 every time during installation. Workers only need to perform glue application at the first groove 11 and the second groove 12 of the tray 1, so that the position and angle of each installation are the same, thereby ensuring the installation accuracy of the label printer movement.

[0041] like Figure 1-4 As shown, the second part of the present application also proposes a method for installing a label printer movement, comprising the following steps:

[0042] Step S1, wearing finger cots and anti-static wristband;

[0043] The thumb, index finger and middle finger are all covered with finger cots to protect the fingers. One end of the anti-static wristband is put on the left or right wrist of the worker, and one end of the anti-static wristband is connected to the ground to prevent the worker from getting an electric shock.

[0044] Step S2, attaching the print head 2 to the movement bracket 3 to form a movement module, and welding the circuit board 4 to the movement module; specifically includes:

[0045] The movement bracket 3 is placed flat on the welding table, double-sided tape is pasted on the upper surface of the movement bracket, and the bottom surface of the print head is bonded to the double-sided tape on the movement bracket to form a movement module, which can make the print head and the movement bracket bonded more firmly. At the same time, the circuit board is welded to the movement module by an ultrasonic welding machine and flux, which can make the welding of the print head and the circuit board more firmly; wherein the flux includes a deoxidation layer, a solvent layer and an adhesive layer, the deoxidation layer is made of ferrous chloride, the solvent layer is made of isopropyl alcohol, and the adhesive layer is made of acrylic acid.

[0046] Step S3, placing the movement module into the second groove of the tray, and placing the circuit board into the first groove of the tray; specifically includes:

[0047] Step S31, placing the first movement module into the second groove of the tray;

[0048] Step S32, placing the first circuit board flatly in the first groove of the tray, wherein the first circuit board matches the first movement module;

[0049] Step S33, placing the second movement module into another second groove of the tray;

[0050] Step S34, placing the second circuit board flatly in the first groove of the tray, and the second movement module cooperates with the second circuit board.

[0051] There are multiple second grooves on each tray, and there is one first groove. When there are two second grooves, the first movement module can be placed in the second groove of the tray first, and then the first circuit board can be placed flat in the first groove of the tray, and then the second movement module can be placed in another second groove of the tray, and finally the second circuit board can be placed flat in the first groove of the tray, so that multiple label printer movements can be installed on the tray, synchronous glue dispensing can be achieved, and the operation intensity of workers can be reduced; at the same time, it can also facilitate the subsequent assembly process of the movement module, circuit board and paper bin, and improve the efficiency of subsequent assembly work.

[0052] Step S4, lift the tray and rotate it along the roller axis by 30°-60°, preferably 45°;

[0053] The pallet can be lifted to an appropriate height according to the height of the worker, and the pallet and label printer movement can be rotated 30° along the roller axis to increase the glue dispensing area between the movement bracket and the circuit board, making it easier for workers to operate.

[0054] Step S5, performing glue dispensing on the core module and the circuit board; specifically comprising:

[0055] Step S51, dispensing glue on the overlapping area of ​​the circuit board and the movement bracket on the movement module by using a dispensing gun;

[0056] Step S52, adjusting the temperature in the ultraviolet oven to 60°C to 120°C, preferably to 90°C, placing the glued circuit board and movement module into the ultraviolet oven for 60 seconds to 80 seconds, preferably for 70 seconds.

[0057] Among them, after the circuit board is attached to the print head on the movement module, and then installed on the movement bracket on the movement module, there is an overlapping area between the edge of the circuit board and the movement bracket. During subsequent processing, the circuit board will bend, so there is a risk of the circuit board falling off. Workers can use a glue gun to glue the overlapping area of ​​the circuit board and the movement bracket on the movement module. After glue, put the tray with the circuit board and the movement bracket into the ultraviolet oven together; workers can adjust the temperature in the ultraviolet oven to 90℃, bake it for 70s, and then take it out, which can improve the efficiency of gluing the circuit board and the movement bracket. In addition, the tray can be made of ABS plastic, which is polymerized from three monomers: acrylonitrile, butadiene and styrene. ABS plastic has excellent physical and mechanical properties, such as good toughness, impact resistance, heat resistance, and chemical corrosion resistance, which can improve the service life of the tray.
