The tape support structure 3 provides tape and attaches it to the connection between the front and rear tapes. The pressing structure 2 presses the tape, and the conveying structure 6 conveys the rear tape. When the required length is reached, the cutting structure 4 cuts the tape to achieve tape splicing.
[0020] Furthermore, the pressing structure 2 includes two linear modules 201 respectively installed on both sides of the base 1. Each linear module 201 has a first cylinder 202 connected to its movable slide. The telescopic ends of the two first cylinders 202 are connected to the pressing roller shaft 203 through bearing seats and bearings. The linear modules 201 are installed on the base 1 by bolts.

The first cylinders 202 can drive the pressing roller shaft 203 to rise and fall. The linear modules 201 can drive the pressing roller shaft 203 to move horizontally through the first cylinders 202.
[0021] Furthermore, the receiving adhesive tape support structure 3 includes a second bracket 308 installed on the top of the base 1 and located on one side of the pressing structure 2. The top of the second bracket 308 is connected to a first support shaft 301 through a bearing seat and a bearing. A first baffle 302 is fixedly sleeved on the outer surface of the first support shaft 301. The second bracket 308 is installed on the top of the base 1 by bolts. The outer surface of the first support shaft 301 is used to sleeve the receiving adhesive tape roll.
[0022] Furthermore, the receiving adhesive tape support structure 3 also includes a first bracket 303 installed on the top of the base 1 and located on the other side of the pressing structure 2. The top of the first bracket 303 is connected to an air shaft 304 through a bearing seat and a bearing. A second baffle 305 is fixedly sleeved on the outer surface of the air shaft 304. The first bracket 303 is installed on the top of the base 1 by bolts. The air shaft 304 is used to sleeve the roll of recycled adhesive tape film.
[0023] Furthermore, a first mounting plate 307 is mounted on the back of the first bracket 303, and a first motor 306 is mounted on the top of the first mounting plate 307.

[0024] Furthermore, the cutting structure 4 includes a support frame 403 mounted on the top of the base 1. A second cylinder 401 is mounted on the top of the support frame 403. The telescopic end of the second cylinder 401 passes through the support frame 403 and extends into the support frame 403 and is connected to a knife holder. A cutter 402 is mounted on the knife holder. The second cylinder 401 can drive the knife holder and the cutter 402 to rise and fall. When the cutter 402 falls, it can cut the material strip. The second cylinder 401 is also a double-rod cylinder.
[0025] Furthermore, the conveying structure 6 includes two third cylinders 601 respectively installed on both sides of the base 1.

[0028] Furthermore, the top of the base 1 is connected to a guide roller 503 via a bearing and a bearing housing. The guide roller 503 is located between the conveyor roller 604 and the second support shaft 501. The guide roller 503 can guide the downstream material belt so that the downstream material belt can enter the trough 101 more smoothly.
[0029] The base 1 is also equipped with a control panel 7, which controls the operation of the linear module 201, the first cylinder 202, the first motor 306, the second cylinder 401, the third cylinder 601, and the second motor 603. The receiving tape consists of a tape film and multiple tape bodies evenly arranged on the tape film. The tape bodies are used to adhere two sections of material tape, and the tape film can be recovered via the air expansion shaft 304.
[0030] The SMT automatic tape splicing machine provided by this invention is used as follows: The tail end of the front section of the material strip is placed into the material trough 101 from the end of the base 1 away from the material-carrying structure 5. Then, the rear section of the material strip is introduced into the material trough 101 from below the guide roller 503 and the conveyor roller 604. The third cylinder 601 drives the conveyor roller 604 to descend, while the second motor 603 drives the conveyor roller 604 to rotate. The rear section of the material strip is conveyed to the front section of the material strip through the conveyor roller 604. When the ends of the two material strips contact each other, the second motor 603 stops. The pressing roller shaft 203 descends to stick the main body of the receiving adhesive tape between the two material strips. Then, the linear module 201 drives the pressing roller shaft 203 to reciprocate through the first cylinder 202 to press the main body of the adhesive tape to stick it on the material strip.
