[0002] When the circuit board is functionally tested, in order to improve the detection efficiency and avoid manually placing the circuit boards one by one, a loading table is usually used to feed the detection equipment. During the use of the loading table, it is generally necessary to place the stacked circuit boards on the loading table and feed them through a single loading table. When the circuit board materials on the loading table are supplied, the equipment needs to be stopped to place the circuit board materials. After the placement is completed, the material stacking height on the loading table exceeds the detection position of the detection sensor. After the detection sensor detects the circuit board, it feeds back the corresponding detection result to the control system, and determines that there is material on the loading table. Then the equipment restarts to load and detect the circuit board. This method has a great impact on the overall production efficiency of factories that require high-speed operation, high output, and high utilization rate.

[0014] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] See also Figure 1 The utility model provides a non-stop cyclic automatic feeding machine, comprising: an equipment outer frame 1, and two groups of material tables 2 arranged inside the equipment outer frame 1, the material table 2 comprises: a waiting table 21 arranged at the bottom of the equipment outer frame 1, and a loading table 22 that moves up and down reciprocatingly at one end of the waiting table 21, and the two groups of material tables 2 are respectively arranged on the left and right sides of the equipment outer frame 1.

[0016] During operation, the operator places the materials on the left and right groups of waiting tables 21 respectively, moves the materials to the corresponding positions of the loading table 22 through the waiting tables 21, and then starts the loading table 22 to lift the materials upward so that the material picking manipulator arranged above can pick up the materials. Since two groups of material tables 2 are provided for feeding respectively, after all the materials on one side of the material table 2 are supplied, the material picking manipulator can pick up the materials from the other side of the material table 2, thereby realizing non-stop feeding. After the loading table 22 lifts the materials upward, the operator can place the next group of materials on the waiting table 21. When all the materials on the loading table 22 are taken away, the loading table 22 moves downward, and then the materials to be tested are moved to the loading table 22 through the waiting table 21, so that after the materials on the other group of loading tables 22 are taken away, non-stop staggered feeding can be carried out, thereby improving the overall testing efficiency.

[0017] The material waiting table 21 includes: a material waiting table frame 211 arranged at the bottom of the inner part of the outer frame 1 of the equipment, and a transportation mechanism 212 arranged on the material waiting table frame 211.

A right-angle baffle 213 is provided on one side edge of the material waiting table frame 211. When the material is placed on the material waiting table 21, the edge of the material can be aligned by the right-angle baffle 213, and then the material can be moved to the corresponding position of the loading table 22 by the transportation mechanism 212, so that the loading table 22 can lift the material, so that it can be picked up by the material picking robot and moved to the test equipment for functional testing of the circuit board.

[0018] The loading platform 22 includes: a loading drive motor disposed inside the outer frame 1 of the device, a transmission mechanism 221 connected to the output end of the loading drive motor, a fixed plate 222 disposed on the output end of the transmission mechanism 221, and a plurality of lifting blocks 223 equidistantly distributed on the fixed plate 222. In some embodiments, the transmission mechanism 221 adopts a lead screw moving module, the output end of the loading drive motor is connected to the lead screw, driving the lead screw to rotate, thereby driving the lead screw slider sleeved on the lead screw to reciprocate in the up and down directions, and the fixed plate 222 is disposed on the lead screw slider, thereby driving the fixed plate 222 to move up and down. The lifting blocks 223 equidistantly distributed pass through the gaps between the feeding belts of the waiting platform 21, so as to facilitate lifting the materials from the bottom of the transport mechanism 212.

[0019] A whole-plate device 3 is provided at the top of the equipment outer frame 1 corresponding to the loading platform 22, and the whole-plate device 3 includes: a mounting plate 31 arranged on the top of the equipment outer frame 1, a plurality of cantilever plates 32 movably arranged on the mounting plate 31, a positioning block 33 arranged on the cantilever plate 32, a whole-plate cylinder 34 arranged on one side of the positioning block 33, and a whole-plate block 35 arranged on the output end of the whole-plate cylinder 34, the cantilever plate 32 extends the positioning block 33 to the corresponding position of the loading platform 22 facing the front side of the equipment outer frame 1 and / or the side of the loading platform 22, and the whole-plate cylinder 34 pushes the whole-plate block 35 toward the loading platform 22. When the loading platform 22 moves the material to the material picking height, the whole board device 3 is started, and the whole board cylinder 34 pushes the whole board 35 to move toward the material, and then pushes the material from the side, so that the top corner of the material is flush with the upper right corner of the loading platform 22, so that it is convenient for the material picking robot to pick up the material and ensure that the material picked up each time is kept in the same position, which is convenient for the testing machine to detect the performance of the circuit board.

[0020] The mounting plate 31 and the cantilever plate 32 are both provided with strip holes, and the cantilever plate 32 is provided with a locking seat 36, which is mounted on the mounting plate 31 and the cantilever plate 32. The locking seat 36 is provided with a locking bolt, and a nut is provided below the mounting plate 31 corresponding to the locking bolt, and the locking bolt passes through the strip holes on the cantilever plate 32 and the mounting plate 31 and is locked in the nut. The relative position relationship between the cantilever plate 32 and the mounting plate 31 is adjusted through the strip holes, thereby adjusting the setting position of the positioning block 33, so as to make corresponding adjustments according to circuit boards of different specifications and sizes, and meet the whole board alignment requirements of circuit board materials of different specifications.

[0021] The whole plate 35 is provided with a positioning plate, and the positioning plate is provided with an inclined surface toward the loading platform 22. By providing the positioning plate, when the material taking manipulator moves downward to take materials, the inclined surface on the positioning plate can guide the edge of the material taking manipulator, so that the material taking manipulator can pick up materials easily and avoid collision between the material taking manipulator and the whole plate device 3, thereby improving safety.

[0022] The specific working process of the automatic feeding machine provided by the utility model is as follows:

[0023] 1. Two groups of material platforms 2 are arranged on the left and right sides of the outer frame 1 of the equipment, and each group of material platforms 2 includes a material waiting platform 21 and a material loading platform 22.

[0024] 2. The operator first places the material close to the right-angle baffle 213 of the waiting table 21, aligns the edges of the material, then starts the waiting table 21, sends the feeding information to the waiting table 21, starts the transportation mechanism 212, and moves the material to the loading table 22. The loading table 22 receives the rising signal, starts the loading drive motor, and lifts the material. When the loading table 22 lifts the material, the operator can place the next group of materials on the waiting table 21 in advance, and after the current material is taken, the next group of materials can be quickly moved to the loading table 22.

[0025] 3. After the loading platform 22 lifts the material into place, the light emitted by the photoelectric sensor arranged on the outer frame 1 of the equipment detects the object and sends a corresponding detection signal to the control system, which then sends a corresponding control signal to the loading platform 22 through the control system, driving the loading platform 22 to stop working.

[0026] 4. Align the material picking robot with the test frame to confirm that the board placement parameters are correct.

[0027] 5. The material picking robot moves to the top of the right loading table 22, picks up the first material on the top, places the material on the center line body, waits for the center line body press to be pressed for testing, and after obtaining the test results and data, moves the tested circuit board material to the unloading table for unloading.

[0028] 6. When the materials on the right loading platform 22 are taken, the material taking manipulator moves to the top of the loading platform 22 of the left loading platform 2 to take the materials. At this time, the right loading platform 22 moves downward, and after it is in place, the material waiting platform 21 of the right loading platform 2 moves the materials to be tested to the loading platform 22. After being transported to the right place, the loading platform 22 automatically rises, so that after the materials on the left loading platform 22 are completely taken, it can be switched to the right loading platform 22 for feeding. In this way, by switching between the left and right loading platforms 2, staggered feeding without stopping is realized, which effectively improves the overall testing efficiency.

[0029] In summary, the utility model is provided with two groups of material tables for feeding respectively. After all the materials on one side of the material table are supplied, the material taking robot can pick up the materials from the other side of the material table, thereby realizing non-stop feeding. After the material is lifted upward on the loading table, the operator can place the next group of materials on the waiting table. When all the materials on the loading table are taken away, the loading table moves downward, and then the materials to be tested are moved to the loading table through the waiting table, so that after the materials on the other group of loading tables are taken, non-stop staggered feeding can be carried out, thereby improving the overall testing efficiency.
