Description

A belt-type bulk material feeder for a chip mounter Technical Field

[0001] This utility model relates to the field of chip mounter technology, specifically to a tape-type bulk material feeder for chip mounters. Background Technology

[0002] In the field of surface mount technology for electronic components, the tape feeder of the pick-and-place machine is a key device for achieving efficient and automated production. Especially in small-batch prototyping production, the tape material is usually supplied in the form of cut-off loose material, which is picked up by the pick-and-place head for feeding.

[0003] Traditional belt conveyor systems typically arrange bulk materials in a standardized manner within a feeding hopper, which is then picked up sequentially by a picking head. However, this method requires manual pushing of subsequent bulk materials to the picking position, making the feeding process inconvenient. Therefore, existing technologies further utilize automated feeding methods, employing a jog-driven propulsion structure to automatically feed subsequent bulk materials, thereby improving production efficiency.

[0004] However, since most inching propulsion structures usually coordinate with the feeding head by matching the time difference interval, if there is a delay in the feeding head's movement or an accumulation of dynamic coordination error, it is easy to cause misalignment between the feeding action and the feeding action, resulting in poor synchronization. Summary of the Invention

[0005] The purpose of this utility model is to provide a belt-type bulk material feeder for a chip mounter, so as to solve the technical problem of poor synchronization caused by the feeder feeding material by matching the action time of the pick-up head in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] A belt-type bulk material feeder for a chip mounter includes a housing, on which a material inlet is provided;

[0008] An annular chain belt is rotatably disposed within the housing. The annular chain belt is provided with multiple material level grooves and multiple baffles, and the interval between adjacent baffles is equal to the interval between adjacent material level grooves.

[0009] A magnetic block is reciprocally slidably disposed on the housing via an elastic structure. The magnetic surface of the magnetic block is positioned close to the feeding port. The magnetic block is driven away from the feeding port by a mating block with opposite magnetic properties on the feeding head. The magnetic block is connected to a one-way rotating paddle, which extends downward and is movably connected to the baffle. Under the linear sliding of the magnetic block, the one-way rotating paddle sequentially pushes multiple baffles to move towards the feeding port.

[0010] As a preferred embodiment of this utility model, the unidirectional rotating paddle includes a diagonal spring, a paddle, and a limiting straight plate arranged sequentially at the bottom of the magnetic block. The diagonal spring is arranged close to the material inlet, and the limiting straight plate is arranged away from the material inlet. One end of the diagonal spring is arranged at the bottom of the magnetic block, and the other end is fixedly connected to the paddle. One end of the paddle is rotatably connected to the bottom of the magnetic block, and the other end extends downward and is arranged on one side of the baffle.

[0011] In a preferred embodiment of this utility model, the elastic structure includes a return spring fixedly connected to the magnetic block, the other end of the return spring being fixedly mounted on a support member, and the support member being fixedly mounted on the housing.

[0012] As a preferred embodiment of this utility model, the housing is provided with a feed inlet, and a feeding structure is provided at the feed inlet. The feeding structure is connected to the magnetic block, and the magnetic block synchronously drives the material level groove to move forward and the feeding structure to replenish material through reciprocating linear sliding.

[0013] As a preferred embodiment of this utility model, the feeding structure includes a feeding trough, a sliding channel, and a push rod. The feeding trough is formed on the housing and is located near the feeding port. The sliding channel is connected inside the feeding trough and is inclinedly arranged on one side of the housing. A push rod is provided inside the feeding trough and is slidably connected to the housing. The other end of the push rod is fixedly connected to the magnetic block.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This invention utilizes the dynamic interaction of the magnetic repulsion between the magnetic block and the mating block on the picking head, along with the elastic return of the return spring, to drive a unidirectional rotating paddle. This creates a real-time mechanical feedback link between the stepping push of the material level slot and the picking action. During the material picking process, the magnetic block is triggered to move backward immediately. After picking, the preload of the return spring pushes the magnetic block forward, causing the paddle to move the baffle and achieve precise advancement of the material level slot. This significantly improves the synchronization accuracy between the feeding cycle and the mounting action, resulting in faster feeding response and smaller cumulative dynamic errors. Furthermore, the magnetic block is synchronously connected to the feeding structure, replenishing the material level slot while feeding, further improving process synchronization and increasing production efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As shown in Figures 1 to 4, this utility model provides a belt-type bulk material feeder for a chip mounter, including a housing 1. The housing 1 has a material inlet 2 for the pick-up head of the chip mounter to pick up materials. An annular chain belt 3 is installed inside the housing 1. The annular chain belt 3 uses a metal chain or a flexible rubber belt for rotary rotation. The annular chain belt 3 is rotatably mounted inside the housing 1. The annular connection can be driven by friction via a rotating roller, or by gear meshing, as shown in Figure 2. By utilizing the meshing of gears with the grooves on the inner wall of the annular chain belt 3, the forward movement of the material level slots 4 can be more precisely controlled. The annular chain belt 3 is provided with multiple material level slots 4 and multiple baffles 5. The material level slots 4 and baffles 5 are arranged along the annular trajectory of the annular chain belt 3 on its outer surface. The spacing between adjacent material level slots 4 and adjacent baffles 5 is equal. The material level trough 4 is used to place the belt-type bulk material. The belt-type bulk material is placed in the material level trough 4 with the pins facing down and the body facing up, so that when the material level trough 4 moves to the material pick-up port 2, it can be picked up by the material pick-up head.

[0026] The spacing between adjacent baffles 5 is equal to the spacing between adjacent material level slots 4, so that the unidirectional rotating paddle 9 can be located on one side of the baffle 5 each time it retracts a fixed distance, thereby effectively pushing the baffle 5 forward. Specifically, the baffle 5 can be arranged between two adjacent material level slots 4 as shown in Figure 3. A magnetic block 6 is provided on the housing 1. The magnetic block 6 is reciprocally slidably arranged on the housing 1 through an elastic structure 7. The elastic structure 7 includes a return spring 71 fixedly connected to the magnetic block 6. The other end of the return spring 71 is fixedly arranged on a bracket 72, which is fixedly arranged on the housing 1. The magnetic surface 8 of the magnetic block 6 is located near the feeding port 2. The magnetic surface 8 of the magnetic block 6 is a magnetic surface. This magnetic surface 8 is used to match the mating block on the feeding head. The feeding head is provided with a mating block with the opposite magnetic properties to the magnetic surface 8 of the magnetic block 6.

[0027] When the feeding head descends to the feeding port 2 to collect material, the mating block, due to the repulsion mechanism of opposite magnetic poles, pushes the magnetic block 6 to slide on the housing 1, thereby driving the one-way rotating paddle 9 to move to the lower baffle 5. The magnetic surface 8 can be set as a large plane to obtain greater magnetic force, and as shown in Figure 1, the magnetic surface 8 is tilted upwards to ensure more comprehensive contact with the mating block moving downwards. The magnetic block 6 is driven by the mating block on the feeding head with opposite magnetic poles in a direction away from the feeding port 2. The magnetic block 6 is connected to the one-way rotating paddle 9, as shown in Figure 3. The one-way rotating paddle 9 can only rotate towards the feeding port 2 and cannot rotate away from the feeding port 2. Therefore, when the magnetic block 6 drives the one-way rotating paddle 9 to slide away from the material inlet 2, under the action of the baffle 5, the one-way rotating paddle 9 rotates and retracts towards the material inlet 2, and will not push the annular chain 3 to rotate. However, when the magnetic block 6 moves forward under the drive of the elastic structure 7, the one-way rotating paddle 9 can drive the baffle 5 to move, thereby realizing the rotation of the annular chain 3 and the advancement of the material level groove 4. The one-way rotating paddle 9 extends downward and is movably connected to the baffle 5. Under the linear sliding of the magnetic block 6, the one-way rotating paddle 9 sequentially pushes multiple baffles 5 to move towards the material inlet 2.

[0028] Specifically, the one-way rotating paddle 9 has various implementations in the prior art, such as electronic paddles, pneumatic paddles, and ratchet paddles. This utility model provides an implementation of the one-way rotating paddle 9, which has a simple structure, requires no driving components, and has lower manufacturing and maintenance costs. Specifically:

[0029] As shown in Figure 3, the one-way rotating paddle 9 includes a diagonal spring 91, a paddle 92, and a limiting plate 93 arranged sequentially at the bottom of the magnetic block 6. The diagonal spring 91 is located near the material inlet 2, and the limiting plate 93 is located away from the material inlet 2. One end of the diagonal spring 91 is located at the bottom of the magnetic block 6, and the other end is fixedly connected to the paddle 92. One end of the paddle 92 is rotatably connected to the bottom of the magnetic block 6, and the other end extends downward and is located on one side of the baffle 5.

[0030] As shown in Figures 1 and 4, in order to improve the feeding efficiency of the feeder and the synchronization of the feeding, loading, and unloading processes, a feed inlet 10 is further provided on the housing 1. The feed inlet 10 is located above the annular chain belt 3, and loose material can pass through the feed inlet 10 to the material level groove 4 on the stationary annular chain belt 3. A feeding structure 11 is provided at the feed inlet 10, and the feeding structure 11 is connected to the magnetic block 6. The magnetic block 6 synchronously drives the material level groove 4 to move forward and the feeding structure 11 to replenish material through reciprocating linear sliding.

[0031] Specifically, the feeding structure 11 includes a feeding trough 111, a sliding channel 112, and a push rod 113. The feeding trough 111 is located on the housing 1 and is positioned near the feed inlet 10. To improve the accuracy of the bulk material entering the material level trough 4 from the feeding trough 111, a guide plate can be installed at the opening of the feeding trough 111. The guide plate is inclined towards the material level trough 4. When the bulk material slides out of the feeding trough 111, it is guided downward into the material level trough 4 by the guide plate. The sliding channel 112 is connected inside the feeding trough 111. The sliding channel 112 is inclined on one side of the housing 1, and the other end of the sliding channel 112 can be connected to a hopper. The bulk material is spread flat in the sliding channel 112 and slides into the feeding trough 111 under the action of gravity. A push rod 113 is installed inside the feeding trough 111. The push rod 113 is slidably connected to the housing 1, and the other end of the push rod 113 is fixedly connected to the magnetic block 6. When the feeding head drops to pick up material, the magnetic block 6 slides backward, moving the one-way rotating paddle 9 to the lower baffle 5. At the same time, the push rod 113 pushes the loose material in the feeding trough 111 from the feeding port 10 into the material level trough 4 for replenishment. Then, the magnetic block 6 returns to its original position under the action of the reset spring 71. At this time, the one-way rotating paddle 9 drives the ring chain belt 3 to rotate, forming feeding, and the magnetic block 6 drives the push rod 113 to move, exposing the controlled feeding trough 111. At this time, the loose material on the sliding channel 112 falls into the feeding trough 111, realizing cyclic replenishment.

[0032] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
