Material support device for placement machine

The present invention relates to a jig, and more particularly to a material support device for use in a placement machine in the SMT field.

In the field of SMT (Surface Mount Technology), the placement machine is the most important equipment in SMT production technology, mainly including the body, component feeders, and placement heads. The body is used to install and support various components of the placement; the function of the feeder is to transfer the components to the reclaiming part of the body according to a certain regularity and sequence, and the feeder has a larger number in the placement machine and occupies more Large position, an important part of the placement machine. With the increasing speed and accuracy requirements of the placement, the installation and design of the feeder has received more and more attention. Because the variety of components and packaging types are different, the specifications of the feeders are not the same, which causes the feeder motor that supplies power to the feeder to be overloaded during production, and the components are supplied. An abnormal phenomenon has occurred. In order to reduce the overload of the motor, the conventional method uses a rod-fixed fixture to support the material to achieve the purpose of reducing the overload of the motor drive. Although the rod-core fixed jig can complete the work of supporting materials, the structure is large, the fixing method is single, and the operation is cumbersome. The most important rod core is fixed, and the entire fixture is manufactured in one piece, which cannot meet the support needs of different kinds of materials. If different supporting fixtures are manufactured according to different materials, it will undoubtedly increase financial expenses and increase production costs, so a more versatile material supporting fixture is needed.

In view of the above, it is an object of the present invention to provide a material support device for a placement machine that is simple to use and more versatile to overcome the above-mentioned drawbacks of the prior art.

FIG. 1 to FIG. 4 show a material supporting device for a mounting machine according to the present invention. The present invention is essentially a supporting fixture including a support rod 1, a boom 2 and a support plate 3. The support rod 1 can be The detachable connection is at one end of the boom 2, and the end of the support rod 1 is provided with a baffle 14 , and the other end of the jib 2 is fixedly connected to the bottom surface of the support plate 3 , the support rod 1 includes a first rod core 11 , Two rod cores 12 and a sleeve 13, the baffle 14 is at one end of the sleeve 13, the first rod core 11 is fixed on the boom 2, and the second rod core 12 is fixed in the sleeve 13 and adjacent to the side of the baffle 14 The sleeve 13 is detachably sleeved on the first rod core 11. The first rod core 11 and the second rod core 12 are rod-shaped magnets, and the rod-shaped magnets of the two rod cores 11 and 12 are sleeved. The opposite poles are opposite, so that after the socketing, because of the principle of heteropolar attraction, the two rod magnets can be firmly adsorbed together, which is very convenient to use and does not require other positioning locking devices.

In this embodiment, the angle between the boom 2 and the bottom surface of the support plate 3 is an acute angle. According to experimental tests, the acute angle between 50 and 60 degrees works best, but the acute angle between the boom 2 and the support plate 3 can be fixed at different angles depending on the circumstances.

In the present embodiment, the support rod 1 is perpendicular to the boom 2 and parallel to the bottom surface of the support plate 3.

The boom 2 in this embodiment includes a fixed plate 21 and a connecting plate 22 which are connected together, and the connecting plate 22 is fixedly connected with the first rod core 11 of the support rod 1, and the fixing plate 21 is fixedly connected to the supporting plate On the bottom surface of 3, and as shown in Fig. 4, the width of the fixing plate 21 in the axial direction of the support rod 1 is wider than the width of the connecting plate 22 in the axial direction of the support rod 1. In the present embodiment, the purpose of the fixing plate 21 being wider than the connecting plate 22 is that since a plurality of jigs are placed side by side on the body of the mounting machine in actual operation, the connecting plates 22 of each jig are supported on the connecting plate 22 The material of the feeder can easily interfere with each other between the materials on the adjacent jig connecting plates. When the width of the fixing plate 21 is wider than the connecting plate 22, the distance between the adjacent jigs can be increased during the installation process. The distance, in turn, increases the distance between adjacent materials, avoids mutual interference between adjacent materials, and ensures stable operation of adjacent feeders.

The fixing plate 21 is adjacent to the inner side of one end of the supporting plate 3 to open a limiting groove 212. The limiting groove 212 is used for defining the position of the entire jig to prevent the jig from being displaced due to vibration and the like during operation. A handle 211 is further disposed on the fixing plate 21 for easy access.

In this embodiment, the boom 2 is fixedly connected to the front end of the bottom surface of the support plate 3. The front end of the bottom surface of the support plate 3 is wider than the rear end of the bottom surface of the support plate 3. The front width and the rear narrow structure are designed to prevent phase. Interference occurred between the support plates of the adjacent fixtures. In actual machining, a notch may be directly extended from the intermediate position of the rear end of the support plate 3 toward the front end.

In the present invention, the material of the boom 2 and the support plate 3 are both stainless steel materials.

In actual work, according to the specific working conditions, the placement opportunity at the time of placement provides different kinds of materials because different materials require different support fixtures, and the support fixture of the present invention can support different belts as needed. Material.

The invention is used for supporting a strip material, and the invention is installed on the body of the placement machine in use. The body of the placement machine is provided with a bracket having a jack 51 and a pressing rod 52, a jack 51 and a pressing rod 52. Connected by the connecting plate 53, combined with FIG. 2, FIG. 5 and FIG. 6, the support plate 3 is inserted between the jack 51 and the pressing rod 52, and the top surface of the supporting plate 3 is pressed under the pressing rod 52, and the supporting plate 3 The bottom surface abuts against the ejector pin 51, and the limiting groove 212 cooperates with the ejector pin 51 to prevent movement. The line contact between the bottom surface of the support plate 3 and the ejector pin 51 prevents the entire jig from shaking. The sleeve 13 is removed, and the sleeve 13 is inserted into the strip material 4 to be supported. The sleeve 13 is sleeved on the first rod core 11 together with the strip material 4, and after being sleeved, the strip material 4 is The packaged components are connected to the body of the placement machine, and the packaged components are sequentially sent to the take-up portion of the body of the placement machine through the feeder motor. Since the first rod core 11 and the second rod core 12 are magnets that are opposite to each other, they do not fall. Since the present invention can support different types of strip materials, the versatility is better, so the load of the feeder motor is effectively reduced, and the installation is very simple.

In summary, the material supporting device for the mounting machine of the present invention has a simple structure and strong versatility. Therefore, the present invention effectively overcomes some practical problems in the prior art and has high utilization value and use significance in SMT production.

The above embodiments are intended to illustrate the principles of the invention and its effects, and are not intended to limit the invention. Any of the above-described embodiments can be modified by those skilled in the art without departing from the spirit and scope of the invention. Therefore, the scope of protection of the present invention should be as set forth in the appended claims.
