Abstract

The present invention provides a shipping tape loading device for improving the problem that the conveying speed of the shipping tape cannot be in high speed because the shipping tape is conveyed intermittently. The shipping tape loading device (1) comprises a tape conveying mechanism (2) for conveying shipping tape (T), and a feeder (3). The feeder (3) conveys the workpiece (W), that is a extremely small object, to a loading stage (2A) formed as a part of the conveying path of shipping tape (T) from a direction that is crossed to the conveying path of shipping tape (T) of the tape conveying mechanism (2). Sucking mechanisms (5, 6) for sucking the workpiece (W) are disposed at a position opposed to the conveying path of shipping tape (T) and the workpiece (W) feeding direction of the feeder (3) and below the loading stage (2A). The workpiece (W) can be quickly moved toward the loading stage (2A) to be in a standby state. When a loading hole (Ta) is located on the loading stage (2A), the workpiece (W) can be immediately inserted into the loading hole (Ta) and the next workpiece (W) can be almost simultaneously moved toward the loading stage (2A) to be in the standby state. Thus, there is no need to intermittently covey the shipping tape (T).

Description

Shipping belt filling device

The present invention relates to a technology for transferring to a target position of a shipping belt or a substrate, which does not cause impact or change the posture of extremely small and precise objects such as electronic parts.

After completing various inspections and the like, extremely small electronic components (hereinafter referred to as extremely small objects) are appropriately transferred to target positions such as shipping tapes and substrates. Regarding the transfer of extremely small objects to the shipping belt, for example, Patent Document 1 (Japanese Patent Publication No. 2004-262529) discloses a technique that separates the extremely small objects one by one without passing through an intermediate unit such as a loading and unloading unit, and loads them in the belt seal. The filling hole on the backing paper of the device.

According to Patent Document 1, this technique is configured such that a conveying unit is provided immediately in front of the front end of a feeder that conveys a row of extremely small objects, and the conveying unit has a lower proximal end and a higher distal end relative to the feeder. Inclined, and a loading tool is provided above the conveying unit. The loading member is configured to move up and down freely. The front surface of the loading member is a stopper for stopping very small objects, and the lower surface is a pressing portion for pressing very small objects to the filling hole of the backing paper. In addition, it also has a small object A suction unit that sucks in the direction of the conveying unit from the feeder.

However, with regard to the structure of Patent Document 1 described above, the extremely small objects that have been loaded in the filling hole receive a pressing impact from the pressing portion of the filling member. In addition, at this time, a very small object separated from the feeder will be impacted by abutting against the stopper of the filling member.

In addition, in the technique of Patent Document 1, when the extremely small objects are not completely filled in the filling hole, the extremely small objects are sandwiched between the filling tool and the edge of the filling hole of the belt, and may be damaged depending on the situation. In addition, if for some reason the pressing of the filling piece and the constant rhythm with the position of the filling hole are broken, the extremely small objects will continue to be clamped by the edges of the filling piece and the filling hole, or the extremely small objects will be filled in the belt position without the filling hole. Pressing may cause damage to very small objects and become inoperable.

In addition, with regard to the structure of Patent Document 1, it is necessary to maintain a constant rhythm in order to avoid the above-mentioned failures. However, there is a possibility that it is difficult to synchronize the stroke pitch of the loading member with the loading hole, and due to this restriction, there are also the following problems. The belt conveying speed can be increased, but the speed cannot be achieved.

(1) Technical problems to be solved

The problem to be solved by the present invention is that, in the prior art, the extremely small object and the filling part are impacted during standby or pressing, which may cause the extremely small object to be damaged. In addition, it may be difficult to synchronize the adjustment of the impact stroke pitch and the filling hole, and it may be possible that although the belt conveying speed can be increased, the speed cannot be achieved due to the constraints of the stroke pitch of the filling material.

(2) Technical solution

In order to solve the above technical problems, the present invention provides a shipping belt filling device, which fills extremely small objects into the filling holes of the shipping belt. The delivery belt loading device has: a belt conveying mechanism that conveys the delivery belt; and a feeder that transfers extremely small objects to the delivery belt from a direction that intersects with the conveying direction of the delivery belt of the belt conveying mechanism. A part of the conveying path is formed as a loading platform for transportation, and a suction for sucking very small objects is provided at a position opposite to the feeding direction of the feeder for the extremely small objects through the conveying path of the shipping belt, and at a position below the loading platform mechanism.

(3) Beneficial effects

In the present invention, the suction mechanism is used to continuously bring extremely small objects from the feeder to the loading table of the belt conveying mechanism, and at the same time, from below the loading table, that is, below the loading hole of the shipping belt, to the very small object close to the loading table. The object is sucked, so that when the loading hole of the shipping belt is located at the loading table, extremely small objects are sucked into the loading hole. Therefore, it is not necessary to intermittently convey the shipping belt in synchronization with the stroke distance of the loaded parts, which can improve the processing efficiency and can suppress the impact or contact of extremely small objects with other structural components. Therefore, it also has the advantage that the possibility of causing defective very small objects to be shipped is extremely low.

The purpose of the present invention is to solve the above-mentioned technical problem, that is, the extremely small object and the filling part are impacted during standby or pressing, which causes the extremely small object to be damaged. In addition, it is difficult to synchronize the adjustment of the impact stroke pitch and the filling hole. In addition, although the belt conveying speed can be increased, it is also restricted by the stroke pitch of the loading material, and the speed cannot be increased. To this end, the shipping belt loading device of the present invention has: a belt conveying mechanism that conveys the shipping belt; and a feeder that directs extremely small objects to the direction that crosses the conveying direction of the shipping belt of the belt conveying mechanism. The loading platform is transported on a part of the conveying path of the shipping belt, and has a suction minimum at a position opposite to the feeding direction of the feeder for extremely small objects across the conveying path of the shipping belt, and at a position below the loading platform. The suction mechanism of the object.

The belt conveying mechanism can convey the outgoing belt by intermittent conveying or constant speed, but there is no need to temporarily stop or constant speed in the present invention, that is, because it does not need to be synchronized with other mechanisms, there is no restriction, even if it occurs There is no problem with unstable conveying speed or high-speed conveying.

The loading table is a part of the belt conveying mechanism connected to the feeder, where very small objects are transferred from the feeder. In addition, the suction mechanism is continuously used from the position opposite to the feeding direction of the feeder through the conveying path of the shipping belt, and the position below the loading table, that is, the loading hole when the loading hole of the shipping belt is located there. The lower position of the suction for very small objects.

The suction mechanism installed at the above two places keeps extremely small objects on standby on the loading platform. When the loading hole of the shipping belt is located on the loading platform, the extremely small object is immediately inserted into the loading hole, and the next extremely small object is immediately made into the loading platform. The standby state. Therefore, the shipping belt loading device of the present invention can suppress the impact or contact of extremely small objects with other structural members, and can improve the processing efficiency.

In the present invention, the suction mechanism at a position opposed to the feeding direction of the extremely small objects of the feeder across the conveying path of the shipping belt, and at a position below the loading table, may be configured such that The positions adopt the method of generating negative pressure to suck extremely small objects or the method of using magnetic force to suck extremely small objects, or the method of generating negative pressure in one position and the method based on magnetic force in the other position.

If it is a suction mechanism based on negative pressure, it can be widely applied to very small objects whose quality will change due to magnetization; if it is a suction mechanism based on magnetic force, it can be more than a suction mechanism based on negative pressure. Accurately and in a stable posture, suck extremely small objects that are not affected by magnetization. Of course, for extremely small objects that are not affected by magnetization, the negative pressure-based method and the magnetic-based method can also be mixed.

In addition, the present invention may be that the loading platform is provided with a nozzle unit, the front and back of the nozzle unit facing in the feeding direction of the extremely small objects of the feeder, and the conveying surface of the delivery belt facing the belt conveying mechanism The bottom surface is formed to be open, and the suction port of the suction mechanism is provided at the back position of the nozzle unit when the feeder side is the front surface.

In this way, the nozzle unit can be used to position the extremely small objects in the standby state on the loading table, and the suction loss of the suction mechanism can be suppressed.

Furthermore, in the present invention, the back surface of the nozzle unit may be closed by a porous sheet, and the suction port of the suction mechanism may be provided on the back side of the porous sheet. This eliminates the need to provide components in the suction mechanism to prevent extremely small objects from being sucked.

In addition, the present invention may be that, with regard to the nozzle unit, the upper surface is arranged to be gradually inclined downward along the bottom surface direction toward the back direction, and at least one of the two side surfaces is arranged such that the distance between the two side surfaces faces The back direction gradually narrows. In this way, extremely small objects can be sucked by the suction mechanism in the back direction and guided by the inner wall of the nozzle unit in a constant posture, thereby further increasing the processing speed.

In addition, the present invention may be that the feeder includes: a feeder body with a hollow inside and a perforated plate provided on the conveying surface; and a positive pressure generating device connected to the feeder body for ejecting from the perforated plate The air generates a positive pressure inside the feeder body; and a guide portion is provided on the upper surface of one side edge of the both side edges of the feeder body orthogonal to the conveying direction of the fine objects. In addition, the downstream side of the feeder main body in the conveying direction is inclined downward with respect to the upstream side, and the side provided with the guide portion is inclined downward with respect to the side not provided.

The feeder of the above-mentioned structure is configured to spray air from the perforated plate by the positive pressure generating device, and therefore it is possible to suspend extremely small objects discharged onto the conveying surface of the feeder main body (that is, the perforated plate).

In addition, the feeder of the above-mentioned structure is configured such that the downstream side of the feeder body with the perforated plate as the conveying surface in the conveying direction is inclined downward with respect to the upstream side, and the side provided with the guide portion is opposite to the side where the guide is not provided. One side of the guide portion is inclined downward. Therefore, the individual extremely small objects that are floating and easy to move have the deviation of the front and rear, upper and lower surfaces, but the individual extremely small objects can be arranged neatly on the guide side and use gravity from upstream (hopper side) to downstream (next process side) )delivery.

In addition, in the present invention, the feeder main body may be provided with a front and rear reversing mechanism that adjusts the front and back of a very small object with a front-rear orientation. Alternatively, the feeder main body is provided with an up-and-down turning mechanism that adjusts the up and down of extremely small objects with up and down orientation.

In this way, the feeder is fully or selectively provided with a front-rear turning mechanism and a vertical turning mechanism, so that the postures of extremely small objects can be reliably aligned on the loading table, and the loading defects on the shipping belt T can be effectively reduced.

And in the figure, the very small objects are enlarged one by one. Therefore, each component of the schematic structure of the shipping tape loading device of the present invention is also shown enlarged.

As shown in FIG. 1, the shipping tape loading device 1 of the present invention charges a very small object W (hereinafter referred to as a work W) into the loading hole Ta of the shipping tape T, and has the following structure.

For example, in this example, 2 denotes a belt conveying mechanism that conveys the delivery belt T linearly. In this example, the belt conveying mechanism 2 adopts a method of continuously moving at a high speed instead of repeatedly temporarily stopping and moving. A loading table 2A is provided in a part of the conveying path of the belt conveying mechanism 2.

3 denotes a feeder connected to the loading table 2A. The feeder 3 is used for conveying the workpiece W to the loading table 2A from a direction orthogonal to the conveying direction of the shipping belt T of the belt conveying mechanism 2, and the following structure is adopted in this example.

As shown in FIG. 3, the feeder 3 has a feeder main body 3A with a hollow inside, and a porous plate 3B is provided on the conveying surface (upper surface) of the feeder main body 3A where the workpiece W is conveyed. The porous plate 3B is formed with countless minute penetrations. hole.

In addition, the hollow housing of the feeder main body 3A provided with a perforated plate 3B on the upper surface (conveying surface) is connected to one end of a spray tube 3a, and the other end of the spray tube 3a is connected to a positive pressure generating device 3C. The device 3C generates a positive pressure inside the feeder main body 3A via the control valve 3b, and ejects air from the perforated plate 3B.

In addition, the feeder main body 3A is provided with a guide portion 3D on the upper surface of one side edge portion of both side edge portions orthogonal to the conveying direction of the workpiece W. In addition, the positive pressure generating device 3C and the control valve 3b of the feeder main body 3A are connected to the control unit C to adjust the amount of air supplied to generate a positive pressure in the feeder main body 3A.

Regarding the feeder body 3A of the above-mentioned structure used in this example, as shown in FIGS. 1 and 3, the downstream side (loading table 2A side) in the conveying direction is inclined downward with respect to the upstream side, and as shown in FIG. As shown in FIG. 3(b), it is installed so that the side on which the guide portion 3D is provided is inclined downward with respect to the side on which the guide portion 3D is not provided.

4 denotes a nozzle unit arranged on the loading table 2A. The nozzle unit 4 is configured as a basic structure in which the front and back surfaces facing each other in the supply direction of the workpiece W of the feeder 3 and the bottom surface of the conveying surface facing the shipping belt T of the belt conveying mechanism 2 are configured to be open.

As shown in FIG. 2, the nozzle unit 4 in this example has a structure in which a perforated plate 4A is provided on the back and closed, and the perforated plate 4A is formed with countless minute through holes. In addition, the upper surface is gradually inclined downward along the bottom surface direction toward the back direction, and one of the two side surfaces on the transport direction side of the shipping belt T is formed so that the distance between the two side surfaces gradually narrows toward the back direction (both side surfaces The distance gradually widens toward the front).

For example, in this example, 5 denotes a suction mechanism (a connected suction nozzle) that sucks from a position opposite to the supply direction of the workpiece W of the feeder 3 across the conveying path of the delivery belt T Air creates negative pressure. In this example, the suction mechanism 5 is provided on the reverse side of the perforated plate 4A, and the perforated plate 4A is provided on the back side of the nozzle unit 4 when the feeder 3 side is the front side.

For example, in this example, 6 denotes a suction mechanism (connected suction nozzle), which is provided at a position below the loading table 2A, that is, the workpiece W supply rail of the feeder 3 The intersection with the conveyance path of the shipping belt T, that is, below the filling hole Ta of the shipping belt T, sucks air and generates a negative pressure. In this example, a hole is formed at the intersection of the loading table 2A, a porous plate 2a is arranged in the hole, and the suction mechanism 6 is arranged on the lower surface of the porous plate 2a.

The relationship between the force P1 of the suction mechanism 5 to suck the workpiece W horizontally from the feeder 3 to the loading table 2A and the force P2 to suck the workpiece W from below the loading table 2A is P1<P2. If P1≧P2, the work piece W will be kept in a sucked state due to the force of sucking the work piece W to the loading table 2A. This may cause even if the loading hole Ta of the shipping belt T is located (conveyed to) the work piece The lower part of W cannot be loaded smoothly.

The shipping tape loading device 1 of the above-mentioned structure operates as shown in FIG. 4. In addition, the illustration of the nozzle unit 4 is omitted in FIG. 4. The feeder 3 is operated to sequentially convey the workpieces W to the loading table 2A of the belt conveying mechanism 2. At this time, when the feeder 3 uses the positive pressure generator 3C to spray air from the perforated plate 3B, the workpiece W discharged to the conveying surface (that is, on the perforated plate 3B) is suspended. They are arranged neatly so as to approach and contact the guide part 3D, and in this state, they move from upstream to downstream using the inclination and dead weight of the feeder main body 3A.

The workpiece W moved from the feeder 3 to the loading table 2A is sucked by the suction mechanism 5 and moved to the loading table 2A in a state guided by the nozzle unit 4 in this posture. The belt conveying mechanism 2 (not performing intermittent conveying) always conveys at a constant speed. Before the loading hole Ta of the shipping belt T reaches the loading table 2A, the workpiece W is placed on the shipment as shown in Fig. 4(a) The state on the belt T.

With respect to the space in the nozzle unit 4 on the loading table 2A, the suction mechanism 6 sucks through the perforated plate 2a from below the intersection of the loading table 2A. In addition, the suction mechanism 5 sucks from the feeder 3 to the loading table 2A, so that the workpiece W transported by the feeder 3 to the vicinity of the loading table 2A is positioned in the nozzle unit 4 and then moved to the loading table 2A. When the delivery belt T is conveyed so that the filling hole Ta is located at the filling table 2A, the workpiece W immediately moves to the filling hole Ta.

After that, on the loading table 2A, before the next loading hole Ta of the shipping belt T is transported, the workpiece W is located between the loading holes Ta and Ta of the shipping belt T, and when the loading hole Ta is transported to the workpiece W In the position, as shown in FIG. 4(b), the workpiece W is immediately inserted into the loading hole Ta by the suction of the suction mechanism 6. Then, the next work W (in the standby state on the feeder 3 side) is positioned between the loading holes Ta and Ta of the shipping belt T on the loading table 2A by the suction mechanism 5. Then, when the next filling hole Ta is at the position where the workpiece W is loaded, the workpiece W is inserted, and the operation is repeated in this manner.

In this way, the shipping tape loading device 1 of the present invention continuously uses the suction mechanism 5 to suck the workpiece W from the feeder 3 to the loading table 2A side, and continuously uses the suction mechanism 6 to suck from below the loading table 2A. Therefore, the workpiece W is always in a standby state on the loading table 2A, and the workpiece W is immediately loaded in the loading hole Ta when the loading hole Ta is at the position where the workpiece W is loaded. Therefore, the belt conveying mechanism 2 does not need to perform intermittent conveyance, and can convey the outgoing belt T continuously at high speed and improve the processing efficiency.

In addition, the feeder 3 of the shipping tape loading device 1 of the present invention may be provided with the following additional structure for operating the workpiece W. For example, the feeder 3 shown in FIG. 5 is equipped with the front-back turning mechanism 31 which adjusts the front and back of the workpiece|work W which has a front-back orientation. In the front-rear reversal mechanism 31, in order to grasp the status of the workpiece W, a camera 31A that photographs the conveying surface is provided at an upper position on the upstream side of the feeder main body 3A. In addition, a solenoid 31B that can protrude and sink in the width direction is provided across the conveying surface side (front) and the non-conveying surface side (back) of the guide portion 3D.

The camera 31A and the solenoid 31B are connected to the control unit C. Based on the data captured by the camera 31A, the control unit C makes the solenoid 31B reach the position of the solenoid 31B when the rear end of the wrong workpiece W reaches the position of the 31B protrudes toward the front side of the guide part 3D.

As shown in FIG. 5(b), the rear end of the workpiece W is pushed by the solenoid 31B, so that the workpiece W is turned by 180° in the width direction, that is, the part that was previously at the rear becomes the front. In addition, the solenoid 31B operates only when a front-to-back error is found in the imaging data of the camera 31A (when the control unit C determines that there is a front-to-back error).

In addition, as shown in, for example, FIG. 6, the feeder 3 is provided with an up-and-down reversal mechanism 32 that adjusts the up and down of the workpiece W having an up-down orientation. In the vertical reversing mechanism 32, in order to grasp the status of the workpiece W conveyed from the upstream, a camera 32A that photographs the conveying surface is provided at an upper position on the upstream side of the feeder main body 3A. In addition, a solenoid 32B capable of protruding and submerging is provided across the conveying surface and the back surface of the perforated plate 3B.

The camera 32A and the solenoid 32B are connected to the control unit C. Based on the data captured by the camera 32A, the control unit C turns the solenoid 32B up and down when the rear end of the wrong workpiece W reaches the position of the solenoid 32B. 32B protrudes toward the conveying surface of the perforated plate 3B.

As shown in Figure 6(b), the solenoid 32B is used to push the rear end of the workpiece W so that the workpiece W is turned 180° in the width direction, that is, the surface that was previously the back (lower) becomes the surface (upper). ). In addition, the solenoid 32B operates only when a vertical error is found in the imaging data of the camera 32A (when the control unit C determines that there is a vertical error).

In addition, in the above-mentioned embodiment of the present invention, the suction mechanism 5 and the suction mechanism 6 both adopt the method of generating negative pressure through suction, but either or both may adopt the method of magnetic suction. In this case, the relationship between the force P1 for sucking the workpiece W horizontally from the feeder 3 to the loading table 2A by the suction mechanism 5 and the force P2 for sucking the workpiece W from below the loading table 2A is P1<P2, Same as the above description.

As described above, the present invention can insert the workpiece W into the loading hole Ta immediately when the loading hole Ta of the shipping belt T is located at the loading table 2A, and thereafter wait for the next workpiece W to be transported to the loading hole Ta, without having to use it. The cargo belt T is conveyed intermittently, so the shipping belt T can be conveyed at a high speed, and the processing efficiency is improved.
