Description

Technical Field

[0001] The invention belongs to the technical field of chip mounter components, and in particular relates to a conveying device for a material belt used in a chip mounter. Background Art

[0002] The chip mounter is a special device for mounting chip components in the electronics industry, also known as a surface mount system. It uses a control system to drive the mounting head to pick up components from the feeder through the mounting head nozzle and mount them on the corresponding pad position of the circuit board, ultimately achieving automatic mounting of circuit board components. The automatic feeding device is one of the main components of the chip mounter, and its main function is to continuously, stably and reliably transport component materials to the pick-up position of the chip mounter.

[0003] The placement machine is mainly composed of a frame, a material tape conveyor, a drive system, a positioning and centering system, a placement head, a feeder, a sensor, a control system and other structures. The feeder is used to provide components or material tapes, and a pull-pin structure is often used to accurately pull the material tape to ensure that the material tape or components can be accurately placed. It is often necessary to drive the material tape forward. In particular, the material tape film on the material tape needs to be torn off in advance for easy placement.

[0004] In the prior art, most of the pull-pin feeder structures used to drive the material tape to move in the placement machine are equipped with a power device during use to accurately pull the material tape so as to drive the material tape to move for easy placement. However, the material tape film needs to be separated from the material tape before placement. After the material tape and the material tape film are separated, not only a power device is required to pull the material tape, but also a special power device is required to pull the material tape film to move so as to recycle the material tape film. The pulling process of separating the material tape and the material tape film increases costs, space and layout limitations, and reduces efficiency. Summary of the invention

[0005] The purpose of an embodiment of the present invention is to provide a conveying device for a material tape for a placement machine, aiming to solve the problem that the material tape film needs to be separated from the material tape before placement. After the material tape and the material tape film are separated, not only a power device is required to pull the material tape, but also a special power device is required to pull the material tape film to move so as to recover the material tape film, which increases the cost, space and layout limitations and reduces efficiency during the pulling process of separating the material tape and the material tape film.

[0009] The adjusting member is rotatably connected to the mounting frame, and the adjusting member is provided with a connecting rod and a reset member. The material strip film bypasses the connecting rod and is clamped between the first transmission member and the second transmission member. The material strip drives the first transmission member to rotate through the material strip so as to drive the material strip film to be transmitted in the opposite direction of the material strip. The separated material strip film tends to be straight until the connecting rod is pressed down to increase the gap between the first transmission member and the second transmission member. The reset member is used to restore the gap between the first transmission member and the second transmission member.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0020] like Figure 1-2 As shown, it is a structural diagram of a conveying device for a material belt for a chip mounter provided in an embodiment of the present invention, comprising: a mounting frame, wherein the mounting frame is provided with a positioning rod 11 for separating the material belt and the material belt film;

[0021] An adjustment component 2, the adjustment component 2 is mounted on the mounting frame, the adjustment component 2 comprises a transmission group 23 and an adjustment member 22, the transmission group 23 is provided with a first transmission member 231 and a second transmission member 232, the first transmission member 231 is mounted on the mounting seat 1, and the second transmission member 232 is mounted on the adjustment member 22;

[0022] The adjusting member 22 is rotatably connected to the mounting frame, and the adjusting member 22 is provided with a connecting rod 221 and a reset member. The material strip film bypasses the connecting rod 221 and is clamped between the first transmission member 231 and the second transmission member 232. The first transmission member 231 is driven to rotate by the material strip so as to drive the material strip film to be transmitted in the opposite direction. The separated material strip film tends to be straight until the connecting rod 221 is pressed down to increase the gap between the first transmission member 231 and the second transmission member 232. The reset member is used to restore the gap between the first transmission member 231 and the second transmission member 232.

[0023] In the embodiment of the present invention, preferably, the conveying device of the material belt of the placement machine can be used to accurately pull the material belt so as to continuously and stably transport the material belt to the material picking position of the placement machine, and the material belt and the material belt film after the material is separated are separated from the material belt during the material belt transportation process, and the material belt film is transported at the same time to facilitate the recovery of the material belt film, the adjustment component 2 is installed on the top surface of the mounting seat 1, the adjustment member 22 is rotatably connected to the mounting seat 1 to facilitate positioning and pulling the material belt, the adjustment member 22 can accurately pull the material belt so that when the material belt is pulled, it drives the first transmission member 231 installed on the mounting seat 1 to rotate, so that the second transmission member 232 connected to the first transmission member 231 rotates at the same time to realize The strip film clamped between the first transmission member 231 and the second transmission member 232 is now driven and tightened for transportation so that it can be separated from the strip film during the conveying process and at the same time the strip film is pulled for easy recovery. The strip moves forward, and the strip film clamped between the first transmission member 231 and the second transmission member 232 is pulled further and further until the strip presses down the connecting rod 221 of the adjusting member 22 to rotate the adjusting member 22.
