Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] A high-speed feeder suitable for dual tracks, such as Figures 1 to 11 As shown, the assembly includes a motor cam assembly 100, a pressing head assembly 200, a receiving block assembly 300, a track mounting base assembly 400, and a track assembly. The receiving block assembly 300 is installed at the front end of the motor cam assembly 100, and the receiving block assembly 300 is used to receive the chips that are dispensed. A pair of track mounting assemblies 400 are also symmetrically installed above the motor cam assembly 100. Each track mounting assembly 400 has a track assembly installed above it. The other end of the track assembly is connected to the main mechanism of the production line. The two track assemblies are connected by the pressing head assembly 200, which is used to press the chips. The track mounting assembly 400 is used to level the track assemblies. The track assemblies are used to continuously move the chips from the main mechanism of the production line to the receiving block assembly 300.

[0036] The motor cam assembly 100 includes a base plate 101 and a sliding plate 103 slidably connected above it. A variable diameter block 104, a first cam follower 105, a first spring hook 106, and a sensor plate 109 are mounted on the sliding plate 103. The variable diameter block 104 is used to limit the movement of the second cam follower 210. A motor 111 is mounted below the base plate 101. An eccentric wheel 112 is mounted on the shaft of the motor 111, located above the base plate 101. A position sensor 110 and a second spring hook 108 are also mounted above the base plate 101. The second spring hook 108 is connected to the first spring hook 106 via a spring 107, which keeps the first cam follower 105 in close contact with the eccentric wheel 112. Both the position sensor 110 and the motor 111 are signal-connected to a controller. The controller can be an external production line controller or a controller integrated into this high-speed feeder, as long as it can perform the above functions.

[0037] When motor 111 drives eccentric wheel 112 to rotate, eccentric wheel 112 drives cam follower 105 to move, which in turn drives moving plate 103 to reciprocate back and forth. The two ends of moving plate 103 reciprocate are the extended position and the retracted position, respectively. The retracted position is when the receiving block retracts to pick up the material; the extended position is when the received chip is extended so that the external mechanism can pick it up. When moving plate 103 moves, it drives sensor chip 109 to move. When position sensor 110 detects sensor chip 109, it transmits the data to controller, and controller controls motor 111 to move in the opposite direction.

[0038] Preferably, the movable plate 103 is connected to the substrate 101 via the guide rail 102.

[0039] The pressing head assembly 200 includes a fixed block 201 and a shaft 204. The fixed block 201 is fixedly connected to the bottom rail of the track assembly. A bearing seat 202 and a cover plate 203 are installed sequentially on top of it. The bearing seat 202 is limited and connected to both ends of the shaft 204. Two oil-free bushings 217 are symmetrically fitted in the middle of the shaft 204. A movable pressure rod is fitted on the outside of each oil-free bushing 217. A first spacer 207 is installed between the two movable pressure rods. A second spacer 216 is installed between each movable pressure rod and the bearing 215. A second cam follower 210 is installed at one end of each movable pressure rod, and the other end is connected to the bearing seat 202 through a pressing head tension spring 212. A pressure head is also installed near the end of the pressing head tension spring 212. The pressure head is used to press the chip. The second cam follower 210 is located below the variable diameter block 104.

[0040] In one or more embodiments, the two movable pressure rods are respectively movable pressure rod 205 and movable pressure rod 206, and the two pressure heads are respectively pressure head 208 and pressure head 209. A tension spring mounting block 211 is installed at one end of movable pressure rod 205 and movable pressure rod 206. A spring hook 213 is installed on the bearing seat 202. The spring hook 213 and the tension spring mounting block 211 are connected by a pressure head tension spring 212.

[0041] The pressure head tension spring 212 ensures that the front ends of the first movable pressure rod 205 and the second movable pressure rod 206 always have a downward force to press the chip. Since the first movable pressure rod 205 and the second movable pressure rod 206 are each internally fitted with an oil-free bushing 217, they can move independently of each other.

[0042] Preferably, both ends of the shaft 204 are connected to the bearing housing 202 via bearings 215 and are limited by snap rings 214.

[0043] The receiving block assembly 300 includes a distributing block mounting base 301 and two distributing blocks 302 and 302 symmetrically mounted on top of it. Both the first and second distributing blocks 302 are used to receive the distributed chips. The distributing block mounting base 301 is fixedly connected to the moving plate 103 below.

[0044] The track mounting bracket assembly 400 includes an adjusting bolt 401, an adjusting bolt mounting base 402, a first mounting block 403, and a second mounting block 404. The adjusting bolt mounting base 402 and the first mounting block 403 are both fixedly connected to the base plate 101. The adjusting bolt 401 is fixedly mounted on the top of the adjusting bolt mounting base 402, and the threaded portion of the adjusting bolt 401 is connected to the first mounting block 403. The first mounting block 403 has an inclined surface on its top, and a guide post that mates with the guide hole of the second mounting block is provided on the inclined surface. The inclined surface also fits against the inclined surface of the second mounting block 404. The second mounting block 404 is fixedly connected to the track assembly on its top. The first mounting block 403 has an elliptical hole. After the bolt passes through the elliptical hole, it is fixedly connected to the base plate, so that the first mounting block 403 can move along the direction of the elliptical hole under the action of the adjusting bolt 401, thereby adjusting the height of the second mounting block 404.

[0045] The track components are track component 500 and track component 600. Track component 500 and track component 600 are the same. Track component 500 includes a bottom rail 501 and a track cover plate 502 installed above it. The bottom rail 501 has a power source that transports the chip and ensures that the chip can move continuously toward the receiving block.

[0046] The working principle of a high-speed distributor suitable for dual tracks is as follows:

[0047] like Figure 8 As shown, the eccentric wheel 112 is in the retracted position at this time, and the first and second feed blocks 302 and 303 are in contact with the bottom rail. The variable diameter block 104 moves synchronously with the feed blocks and is located behind them. At this time, the two cam followers 210 are pressed down by the variable diameter block 104, and the first and second pressure heads 208 and 209 are lifted. At this time, the chip is not restrained in the track and moves towards the receiving block under the action of the rear power. The slot of the receiving block is designed to accommodate one chip exactly. The illustrated state is the chip in the position.

[0048] like Figure 10As shown, motor 111 drives eccentric wheel 112 to rotate at a certain angle. At this time, the first material distribution block 302 and the second material distribution block 303 are in the extended position. If the chip thickness in both tracks is the same, during the process of the variable diameter block 104 moving from the retracted position to the extended position, the two cam followers 210 will lift synchronously, and the first pressure head 208 and the second pressure head 209 will press down under the action of the pressure head tension spring 212 until they press the chip, and the chip stops moving due to the downward pressure. It should be emphasized that after the upstream packaging plant completes the chip packaging, there will always be a certain error in the thickness of the batch of chips. In this mechanism, the first pressure head 208 and the second pressure head 209 can move independently. If the chip thickness in the first track assembly 500 is slightly higher than that in the second track assembly 600, during the process of the variable diameter block 104 moving from the retracted position to the extended position, the first pressure head 208 will press the chip in its track first, while the second pressure head 209 has not yet pressed the chip. However, since the first and second material distribution blocks 302 and 303 have not yet reached their positions, the motor 111 needs to continue driving the eccentric wheel 112 to rotate, and the second pressure head 209 can continue to press down until it presses the chip. After the external mechanism removes the chip from the first and second material distribution blocks 302 and 303, the motor 111 reverses, and the receiving block moves to the position as described above. Figure 8 The state repeats itself in a cycle.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
