DETAILED DESCRIPTION

[0022] The utility model is further described in detail below with reference to the accompanying drawings, and specific implementation methods are given.

[0023] like Figure 1 As shown, a carrier pressing machine includes a mounting frame 1, on which a mounting assembly for mounting a carrier and a pressing assembly for pressing the carrier are provided, the mounting assembly includes a guide rail 2, on which a mounting groove 3 along its length direction is opened, the mounting groove 3 is used to place the carrier and limit the carrier. In the actual design process, the guide rail 2 is bolted to the mounting frame 1, and different guide rails 2 can be replaced according to different types of carriers.

[0024] The pressing assembly includes a heating element, a sealing knife 9 installed on the heating element, and a driving element for driving the heating element to move. The heating element includes a heating block 8 and a heating tube 15 installed on the heating block 8. The heating tube 15 uses an electric heating tube for electric heating in the prior art. The heating block 8 is provided with a mounting hole, and the heating tube 15 is inserted into the mounting hole and fixed (for example, it can be connected by bolts). The pressing assembly also includes a relay 14 and a power switch 4 for electrically heating the heating tube 15. The power switch 4, the relay 14, and the heating tube 15 are connected in series. The power switch 4 controls the on and off of the relay 14, and the relay 14 is used to energize the heating tube 15 to achieve heating.

[0025] Combination Figure 2 As shown, a clamping block is detachably connected to the heating element, and the sealing knife 9 includes a mounting portion 11 for clamping with the clamping block and a pressing portion 12 for pressing the carrier tape. Specifically, the clamping block includes a first clamping portion 10 detachably connected to both sides of the heating element and a second clamping portion 17 movably connected to the first clamping portion 10. The first clamping portion 10 and the second clamping portion 17 surround and form an installation space for clamping the mounting portion 11 of the sealing knife 9, so as to form a circumferential limit for the sealing knife 9. The first clamping portion 10 is L-shaped, and a slot for the mounting portion 11 to be inserted into is formed between the first clamping portion 10 and the heating element, that is, the first clamping portion 10 is bolted to the heating block 8, and a slot is formed between the first clamping portion 10 and the heating block 8. After the mounting portion 11 is inserted into the slot, the second clamping portion 17 is bolted to the first clamping portion 10, and the mounting portion 11 is restricted from sliding in the slot by the second clamping portion 17, thereby realizing circumferential limitation of the mounting portion 11 and preventing the sealing knife 9 from moving on the heating block 8.

[0026] The pressing part 12 is located directly above the mounting assembly, and a packaging groove 13 is provided at the lower end of the pressing part 12. The packaging groove 13 corresponds to the mounting groove 3 and is used to press the carrier tape placed in the mounting groove 3. The lower end of the pressing part 12 protrudes from the lower end of the card block, so that when the pressing part 12 is pressed on the guide rail 2 or in the mounting groove 3, the card block will not interfere.

[0027] During specific use, the carrier tape to be pressed is placed in the installation slot 3, the power switch 4 is turned on, and the heating tube 15 is energized through the relay 14 to achieve heating. The heating tube 15 transfers heat to the heating block 8, and the heat of the heating block 8 is transferred to the sealing knife 9 to heat the sealing knife 9. After heating to a suitable temperature, the heating block 8 is controlled to move downward by the driving member, and the sealing knife 9 moves to the carrier tape to press the carrier tape. After the pressing is completed, the heating block 8 drives the sealing knife 9 to move upward and reset, and the power switch 4 is turned off to cut off the power. In actual use, the driving member can use conventional structures in the prior art such as cylinders, hydraulic cylinders or screw structures, as long as it can drive the heating block 8 to slide back and forth.

[0028] In another embodiment of the present invention, Figure 3 As shown, the pressing assembly also includes a temperature control meter 5 and a temperature controller electrically connected to the relay 14. The signal input end of the temperature controller is used to receive the temperature signal of the temperature control meter 5, and the signal output end of the temperature controller is used to control the driving member to drive the sealing knife 9 to move.

[0029] In this embodiment, combined with Figure 4 As shown, the driving member includes a cylinder 6 and an air pipe 7 connected to the cylinder 6, an electromagnetic valve 16 is installed on the air pipe 7, and the output shaft of the cylinder 6 is fixedly connected to the heating block 8. Specifically, the cylinder 6 includes a cylinder body, a piston slidably connected in the cylinder body, and an output shaft fixed on the piston. The piston divides the cylinder body into two chambers, and the two chambers are connected with air pipes 7. By passing gas into or out of the chamber in the cylinder body, the piston can be driven to slide in the cylinder body by air pressure, and then the output shaft drives the heating block 8 to slide back and forth. The specific structure of the cylinder 6 is a conventional structure in the prior art, and no specific improvement is made, as long as the heating block 8 can be driven to slide by air pressure. In the actual operation process, the air pipe 7 is connected to the air pump, and the air pump is used to pump air or ventilate the air pipe 7, so that the gas enters the cylinder body through the vent pipe 7 or is extracted from the cylinder body through the vent pipe 7, so as to drive the sealing knife 9 to move. The temperature controller controls the opening and closing of the air pump to control the cylinder 6 to drive the sealing knife 9 to move.

[0030] In this solution, the temperature control table 5 uses a temperature control table with heating control in the prior art, and the temperature required for carrier tape pressing is set by the temperature control table. When the temperature reaches the required temperature, the temperature controller controls the driving member to drive the sealing knife 9 to move for pressing.

[0031] In another embodiment of the utility model, the driving member further includes an air pressure controller, which is connected to the electromagnetic valve 16 by signal, and the air pressure controller is used to adjust the opening of the electromagnetic valve 16. In this solution, the opening of the electromagnetic valve 16 is adjusted by the air pressure controller, thereby controlling the amount of gas entering the cylinder 6 through the ventilation pipe 7 and the ventilation speed, thereby controlling the speed at which the cylinder 6 drives the sealing knife 9 to move downward, thereby adapting to the lamination of different types of carrier tapes.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] 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 field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
