Description

Technical Field

[0001] The utility model relates to the field of cooler production equipment, in particular to a solder sheet feeding mechanism for condenser assembly. Background Art

[0002] The cooler is usually composed of flat tubes (or pipes) and fins, which are the two main components of the cooler and are responsible for transferring heat and increasing the heat dissipation surface area to achieve effective heat dissipation. During the production and assembly process, the flat tubes and fins need to be welded and assembled, which requires the use of blanks as welding materials.

[0003] Solder Preform is a solder of a specific shape and size, commonly used in precision welding and mass production. The main function of the solder preform is to provide a certain amount of precisely controlled solder to achieve a uniform and reliable connection during the welding process.

[0004] When the solder sheet is used as the welding material for the flat tube and the fin, it needs to be cut according to the size of the flat tube and the fin. The existing cutting mechanism generally cuts directly through a cutting knife. During cutting, the cutting knife and the solder sheet directly form a large punching force, which can easily cause the solder sheet to bend or shift in position, resulting in inaccurate cut size, too much or too little, affecting the welding and assembly effect of the flat tube and the fin.

DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0018] The utility model provides a brazing sheet feeding mechanism for condenser assembly, such as Figure 1-3As shown, it includes a frame 1, a feed roll 2, a guide roller 3, a motor 4, a conveying roller 5, and a clamping roller 7, which are arranged on the top surface of the frame 1 in sequence from back to front, and the feed roll 2, the guide roller 3, the motor 4, the conveying roller 5, and the clamping roller 7 correspond to each other front to back, the feed roll 2 is rotatably installed at the rear end of the frame 1, a guide roller 3 is arranged in front of the feed roll 2 on the top surface of the frame 1, a motor 4 is arranged at the front end of the guide roller 3 on the top surface of the frame 1, the conveying roller 5 is connected to the output shaft of the motor 4, a cylinder A6 is arranged at the front end of the conveying roller 5 on the top surface of the frame 1, and the clamping roller 7 is connected to the piston end of the cylinder A6, and a cutting unit 9 is arranged between the conveying roller 5 and the cylinder A6 on the bottom surface of the frame 1.

[0019] A cylinder A6 and a clamping roller 7 are arranged between the cutting unit 9 and the conveying roller 5. During cutting, the cutting unit 9 and the cylinder A6 operate synchronously. At this time, the cylinder A6 drives the clamping roller 7 to move in the direction of the conveying roller 5, and cooperates with the conveyed solder sheet to perform a clamping and positioning process to fix the solder sheet at the position where cutting is required, thereby effectively avoiding the pressure generated by the cutting unit 9 during cutting that causes the solder sheet to bend or shift in position, thereby greatly improving the accuracy of position shift cutting.

[0020] As one of the embodiments, the cutting unit 9 includes a cylinder B91 fixedly mounted on the bottom surface of the frame 1, a connecting plate 92 fixedly connected to the piston end of the cylinder B91, a movable tool 93 fixedly mounted on the bottom of the connecting plate 92, and a fixed tool 94 fixedly mounted on the bottom surface of the frame 1. The movable tool 93 is arranged corresponding to the front end of the fixed tool 94. A fine hole is opened in the middle of the connecting plate 92 between the movable tool 93 and the fixed tool 94. The cutting principle is: the solder sheet is transported downward through the fine hole opened in the connecting plate 92 under the action of the motor 4 and the conveying roller 5. During cutting, the cylinder B91 drives the movable tool 93 to move toward the direction of the fixed tool 94 through the connecting plate 92 until the movable tool 93 contacts and cooperates with the fixed tool 94 to cut the solder sheet, and then the cylinder B91 drives the movable tool 93 to reset through the connecting plate 92 to perform the next cutting process.

[0021] Furthermore, two material guide plates 10 are provided on the top of the cutting unit 9, and the two material guide plates 10 are plugged into the frame 1, and a gap for the solder sheet is provided between the two material guide plates 10, and the gap is in an upper and lower corresponding relationship with the fine hole. The two material guide plates 10 are used to receive the solder sheet transported from the motor 4, and at the same time, the two material guide plates 10 are used to position the solder sheet to ensure that the solder sheet corresponds to the fine hole below and passes through the fine hole, so as to avoid the position of the solder sheet affecting the cutting process during transportation.

[0022] Furthermore, the bottom of the fixed tool 94 is fixedly connected to a limit plate 8, and the limit plate 8 is located on the opposite side of the moving tool 93 through the fixed tool 94, and is used to position the solder sheet to avoid the solder sheet moving forward and shifting in position when the moving tool 93 moves to cooperate with the fixed tool 94 for cutting. This not only ensures the cutting accuracy of the solder sheet, but also facilitates the subsequent transportation process of the solder sheet after cutting.

[0023] The working principle of the utility model is as follows: the motor 4 drives the conveying roller 5 to rotate to convey the solder sheet on the supply roll 2, and conveys it to the guide roller 3 to roll and support and guide the solder sheet. When the solder sheet is conveyed to the cutting unit 9 below the motor 4 for cutting, the cylinder B91 is turned on and drives the movable tool 93 to move in the direction of the fixed tool 94 through the connecting plate 92. At the same time, the cylinder A6 drives the clamping roller 7 to move in the direction of the conveying roller 5, and cooperates to clamp and position the conveyed solder sheet, so that the solder sheet is fixed at the position where cutting is required. Finally, the movable tool 93 contacts and cooperates with the fixed tool 94 to cut the solder sheet, thereby effectively avoiding the bending or position displacement of the solder sheet caused by the pressure generated by the cutting unit 9 during cutting, and greatly improving the accuracy of position displacement cutting.
