The clamping holes matched with the clamping rods are formed in the side of the main plate, limiting and clamping between the main plate and the clamping rods are facilitated, and due to the fact that the whole mounting plate can be adjusted in the positioning pressing strip in a sliding mode, the adaptability of the whole clamping edge can be effectively improved, and the clamping edge can be conveniently installed on SMT printing machine lifting bases of different specifications in a matched mode.

Description

Technical Field

[0001] The utility model relates to the technical field of SMT printers, in particular to an edge clamping structure of an SMT printer. Background Art

[0002] The SMT printer is the equipment that prints solder paste onto the PCB board. It is the equipment that has the greatest impact on the process and quality.

[0003] There are three common structures of clamping edges for existing SMT printers: the first is an integrated molding structure, in which the pressing sheet and the positioning strip are made as a whole by machining, and a pressing sheet with a thickness of about 0.15mm is machined on a whole board. This is not only costly but also difficult and inefficient to process. Once damaged, it needs to be replaced as a whole; the second is that the pressing sheet and the positioning strip are fixed by glue. In this structure, since the pressing sheet is subjected to greater force during operation, it is easy for the pressing sheet to be separated from the positioning strip during operation, and the service life is short. It also has the problem of being damaged and requiring overall replacement; the third is that the pressing sheet and the positioning strip are independent of each other. When in use, the positioning strip must be connected to the lifting seat of the SMT printer first, then the pressing sheet must be placed, and then the positional relationship between the pressing sheet, the positioning strip and the lifting seat must be adjusted. However, it is difficult to quickly align the assembly position of the pressing sheet during assembly, which takes a long time to assemble.

[0004] When installing the existing positioning strips, the positions of the mounting holes of the positioning strips are different for the lifting seats of SMT printers of different specifications, resulting in the positioning strips being unable to be adapted and installed on the lifting seats of SMT printers of different specifications, thereby reducing the practicality of the device. In view of this, we propose an SMT printer edge clamping structure. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art, meet actual needs, and provide an SMT printer clamping edge structure to solve the technical problem that when the current existing positioning strips are installed, the positions of the positioning strip mounting holes of SMT printer lifting seats of different specifications are different, resulting in the positioning strips being unable to be adapted and installed on SMT printer lifting seats of different specifications, thereby reducing the practicality of the device.

[0006] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing an SMT printer edge clamping structure, including a positioning pressure strip, a pressure sheet is clamped inside the positioning pressure strip, the positioning pressure strip and the pressure sheet are connected by bolts, a group of mounting plates are clamped on the inner side of the surface of the positioning pressure strip, and a convenient mechanism is provided on the side of the positioning pressure strip;

[0007] The convenient mechanism comprises a connecting rod, a plurality of clamping rods are evenly distributed on one side of the connecting rod, a limiting ring plate is fixedly sleeved outside the clamping rod, and a spring is connected to one side of the limiting ring plate.

[0008] Preferably, the connecting rod and the clamping rod are fixedly connected, and the clamping rod forms an elastic structure through a limiting ring plate, a spring and a positioning strip.

[0009] Preferably, the positioning pressure strip comprises a pressure strip body, a content groove is provided in the middle of the surface of the pressure strip body, a sliding groove is provided on one side of the content groove, and a limiting groove is provided on the other side of the content groove.

[0010] Preferably, the content slot is communicated with the slide slot, and the clamping rod passes through the interior of the limiting slot and reaches the content slot.

[0011] Preferably, the mounting plate comprises a main board, and a limiting plate is fixedly connected to one side of the main board.

[0012] Preferably, the structures of the main board and the content slot match each other, and the main board forms a sliding structure through a limiting plate and a sliding slot.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, a card hole matching the card rod is provided on the side of the main board, which is convenient for limiting engagement with the card rod. Since the mounting plate as a whole can be slidably adjusted in the positioning strip, the adaptability of the clamping edge as a whole can be effectively improved, and it is convenient for adaptation and installation with SMT printer lifting seats of different specifications.

[0015] 2. The utility model pulls the connecting rod outward to make one end of the clamping rod move away from the mounting plate. At this time, a group of mounting plates are not constrained and can effectively slide in the positioning strip. After sliding to the required position, the connecting rod is released, and under the influence of the spring rebound force, two clamping rods are directly engaged in the inside of a group of mounting plates, thereby limiting the group of mounting plates and effectively improving the disassembly and assembly efficiency.

The utility model pulls the connecting rod 501 outward to make one end of the clamping rod 502 away from the mounting plate 4, at which time a group of mounting plates 4 are not constrained and can effectively slide in the positioning pressure strip 1, after sliding to the desired position, the connecting rod 501 is released, and under the influence of the rebound force of the spring 504, two clamping rods 502 are directly engaged in the inside of a group of mounting plates 4, limiting a group of mounting plates 4, and effectively improving the disassembly and assembly efficiency.

[0027] It is worth noting that the positioning pressure strip 1 includes a pressure strip body 101, a content groove 102 is provided in the middle of the surface of the pressure strip body 101, a slide groove 103 is provided on one side of the content groove 102, and a limiting groove 104 is provided on the other side of the content groove 102. Furthermore, the content groove 102 is connected to the slide groove 103, and the clamping rod 502 passes through the limiting groove 104 and reaches the content groove 102. The slide groove 103 in the utility model effectively limits the side of the mounting plate 4 to prevent the mounting plate 4 from slipping out of the positioning pressure strip 1.

[0028] It is worth noting that the mounting plate 4 includes a main board 401, and a limiting plate 402 is fixedly connected to one side of the main board 401. Furthermore, the structures of the main board 401 and the content slot 102 match each other, and the main board 401 forms a sliding structure with the slide slot 103 through the limiting plate 402. In the utility model, a card hole matching the card rod 502 is provided on the side of the main board 401, which is convenient for limiting engagement with the card rod 502.
