Description

Technical Field

[0001] This utility model relates to the field of roll material equipment technology, and in particular to a feeder roll material device for a chip mounter. Background Technology

[0002] A pick-and-place machine, also known as a placement machine, is a core piece of equipment in the SMT (Surface Mount Technology) production line. It is mainly used to mount electronic components onto circuit boards. The pick-and-place machine is a combination of mechanical, electrical, optical and computer control technologies, and is a kind of precision working robot.

[0003] It is important to note that existing pick-and-place machines rely on a roll roller to press and roll the die during the feeding process, thus separating the die from the strip. The existing roll rollers used for pressing the die have smooth surfaces, resulting in low friction and relatively low tension between the outer surface of the roll roller and the die during operation. This can easily lead to incomplete separation between the die and the strip.

[0004] In addition, the existing winding reel and the shaft used to control the rotation of the winding reel have a large rotational resistance. After repeated use, the winding reel made of plastic material is easily damaged, which leads to the need to replace the winding reel frequently and increases the cost of use.

[0005] Therefore, designing a feeder roll device for a chip mounter that can solve the above-mentioned technical problems is a technical issue that needs to be addressed. Utility Model Content

[0006] To address the aforementioned problems, the present invention aims to provide a feeder roll device for a chip mounter, which solves the problem that existing rolls have smooth surfaces, making incomplete peeling easy to occur during the peeling process between the die and the strip, resulting in low peeling efficiency and practicality.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: it includes a bearing for installation and connection with a rotating shaft and a plurality of winding wheels fixedly sleeved on the outer wall of the bearing; the plurality of winding wheels are arranged in parallel at intervals.

[0008] Each of the several coiled reels has trapezoidal pressure blocks spaced circumferentially on its outer peripheral wall. Each pressure block has a connecting groove with an inverted triangular cross-section, open at the front and closed at the rear, along its length. Each pressure block can be detachably connected to a connecting block matching the shape and size of the connecting groove. Guide grooves are formed along the length of the side walls of the connecting groove. Connecting blocks are fixed to the sides of the connecting blocks at positions corresponding to the guide grooves on both sides of the connecting groove. A first mounting groove is formed on one side wall of the blind end of the connecting groove. A second mounting groove is formed at the top of the first mounting groove. A return spring is fixed at the top of the second mounting groove. A limiting block for restricting the movement of the connecting blocks is fixed at the bottom of the return spring, and the bottom end of the limiting block is located within the first mounting groove. One end of the connecting pressure block has a connecting block that mates with the first mounting groove, and the upper surface of the connecting block has a connecting sub-block that mates with the limiting block.

[0009] Furthermore, the number of the coil rollers is two.

[0010] Furthermore, the connecting sub-block includes a triangular connecting portion at the front end and a concave limiting portion at the rear end.

[0011] This utility model has the following beneficial effects:

[0012] 1-This utility model reduces the rotational friction between the material winding wheel and the shaft by fixing a winding wheel on the outer peripheral wall of the bearing and then connecting the bearing to the shaft. This reduces damage to the material reducing wheel and decreases the frequency of replacing the winding wheel compared to the existing connection between the winding wheel and the shaft.

[0013] 2- In this utility model, pressure blocks and connecting pressure blocks are arranged at intervals along the circumference of the outer peripheral wall of the roll wheel to increase the friction on the outer surface of the roll wheel and the friction between the roll wheel and the die, so as to improve the peeling efficiency of the roll wheel and avoid the problem of incomplete strip peeling as much as possible.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0024] See Figure 1-6 As shown, the solution includes a bearing 1 for installation and connection with the rotating shaft and a plurality of winding wheels 2 fixedly sleeved on the outer wall of the bearing 1; the plurality of winding wheels 2 are arranged in parallel at intervals; the above-mentioned bearing 1 and the connection method between the rotating shafts are existing technologies, which are known to those skilled in the art and can be easily implemented, and will not be described here.

[0025] Several of the aforementioned coil rolls 2 have trapezoidal pressure blocks 21 spaced circumferentially on their outer peripheral walls. Each pressure block 21 has a connecting groove 211 with an inverted triangular cross-section, open at the front and closed at the rear, extending along its length. Each pressure block 21 can be detachably connected to a connecting block 22 matching the shape and size of the connecting groove 211. Guide grooves 2111 are formed along the length of both sidewalls of the connecting groove 211. Connecting blocks 221 are fixed on both sides of the connecting block 22 at positions corresponding to the guide grooves 2111 on both sides of the connecting groove 211. The blind end sidewall of the connecting groove 211... A first mounting groove 2112 is provided, and a second mounting groove 2113 is provided at the top of the first mounting groove 2112. A return spring 2114 is fixedly provided at the top of the second mounting groove 2113. A limiting block 2115 for restricting the movement of the connecting block 221 is fixedly provided at the bottom of the return spring 2114, and the bottom end of the limiting block 2115 is located in the first mounting groove 2112. A connecting block 222 that mates with the first mounting groove 2112 is provided at one end of the connecting pressure block 22, and a connecting sub-block 2221 that mates with the limiting block 2115 is provided on the upper surface of the connecting block 222.

[0026] To increase the stability of the connection between the connecting block 221 and the guide slide 2111, the roughness of the contact surfaces of the connecting block 221 and the guide slide 2111 can be increased to increase the friction between them and improve the stability of the connection between the connecting block 221 and the guide slide 2111.

[0027] Optimal, the blind ends of the corresponding connecting grooves 211 on the left and right pressure blocks 21 are opposite each other, which makes it convenient to insert or remove the connecting pressure block 22 into the connecting groove 211.

[0028] In this embodiment, the number of winding wheels 2 on the outer peripheral wall of the bearing 1 is two. Setting the number of winding wheels 2 to two is a preferred implementation method, but it is not limited to this. Different numbers of winding wheels 2 can also be used in other embodiments.

[0029] Optimally, the connecting sub-block 2221 includes a triangular connecting portion 22211 at the front end and a concave limiting portion 22212 at the rear end. When the connecting pressure block 22 extends into the inner wall of the first mounting groove 2112, the connecting portion 22211 of the connecting sub-block 2221 at the top surface of the connecting block 222 at the front end of the connecting pressure block 22 first contacts the limiting block 2115. The limiting block 2115 moves upward along the triangular arc edge of the connecting portion 22211. After the limiting block 2115 passes through the connecting portion 22211, it resets under the elastic action of the return spring 2114 and is located in the groove of the limiting portion 22212. When the connecting pressure block 22 is removed, the limiting block 2115 moves upward along the arc edge of the limiting portion 22212 to move out of the groove of the limiting portion 22212. To improve the connection stability between the connecting block 22 and the guide groove 2111, and to avoid the connecting block 22 from coming out of the guide groove 2111 when the bearing 1 rotates circumferentially.

[0030] The working principle is roughly as follows:

[0031] like Figure 3 As shown in the cross-sectional schematic diagram of this embodiment, the connection between the pressure block 22 and the pressure block 21 is such that when stripping the material strip, there is a gap between adjacent pressure blocks 21, so that the outer peripheral wall of the winding wheel 2 is gear-shaped, which increases the friction between the winding wheel 2 and the die, thereby improving the stripping efficiency.

[0032] like Figure 4 As shown, the connecting block 222 is separated from the pressing block 21. Compared with the connected pressing block 22 and the pressing block 21, a gap (i.e., connecting groove 211) is left between the two ends of the pressing block 21, which increases the number of protruding points of the pressing block 21 on the outer peripheral wall of the winding wheel 2. On the one hand, this further increases the peeling efficiency; on the other hand, when the connecting pressing block 22 is broken or damaged, it is convenient to replace the connecting pressing block 22, reducing the replacement cost.

[0033] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
