When the sliding component 3 moves forward until it touches the electronic components and moves in the reverse direction, the sensing component 5 can control the alarm to sound an alarm.

[0039] In the embodiment of the present invention, a sliding assembly 3 is slidably provided on one side of the transmission seat 2, and a buffer assembly 4 is abutted between the sliding assembly 3 and the transmission seat 2. The sliding assembly 3 can slide forward on the transmission seat and can slide backward when touching the electronic components. The sensing assembly 5 can sense the position of the sliding assembly 3 when sliding, and the alarm can sound an alarm under the control of the sensing assembly 5. Among them, the driving assembly 1 can drive the transmission seat 2 to move forward, so that the transmission seat 2 drives the external suction nozzle mechanism to move. When the suction nozzle mechanism misjudges and squeezes or overlaps the electronic components, the sliding assembly 3 can touch the electronic components and squeeze the buffer assembly 4 to slide backward on one side of the transmission seat 2. The sensing assembly 5 controls the alarm to sound an alarm, so as to prevent the suction nozzle mechanism from continuing to move and damaging the electronic components, strengthen the protection of the electronic components, and thus improve the productivity of the electronic components.

The transmission seat 2 is provided with a first slide rail 24. One side of the first slider 31 is slidably disposed on the first slide rail 24. The fixed block 32 is fixed to the other side of the first slider 31. The cushion block 33 is disposed at the bottom of the fixed block 32, and the cushion block 33 at least partially extends out of the transmission seat 2 for installing one end of the suction nozzle mechanism. When the transmission seat 2 drives the sliding assembly 3 to move downward, the cushion block 33 can contact the electronic components at the bottom and drive the fixed block 32 and the first slider 31 to move upward.

[0050] Specifically, in this embodiment, the first sensing sheet 51 is arranged on the top of the fixed block 32. When the pad 33 contacts the electronic components, the fixed block 32 can move upward, thereby causing the first sensing sheet 51 to move upward. Then, the first sensing sheet 51 moves away from the first sensing element 52, which can cause the alarm to sound. At the same time, the first slider 31 is slidably arranged on the first slide rail 24 to improve the flexibility of the upward movement of the fixed block 32.

[0051] Please also refer to Figures 1 to 4In this embodiment, a limit block 25 is provided on the transmission seat 2, and the limit block 25 is used to limit the stroke of the first slider 31 in the forward direction.

[0053] Specifically, in this embodiment, the first guide member 42 is fixed on the first protrusion 21, and a mounting groove 311 is formed on the fixing block 32. The buffer member 41 at least partially extends into the mounting groove 311, and the buffer member 41 abuts between the bottom wall of the mounting groove 311 and the first guide member 42.

[0054] Specifically, in this embodiment, the first guide member 42 is configured as a guide rod structure, wherein one end of the guide rod passes through the first protrusion 21, and the other end abuts against the bottom wall of the first protrusion 21, and the top of the buffer 41 is connected to the other end of the guide rod, and the guide rod is used to provide a guiding effect on the compression and stretching of the buffer 41 and to achieve a fixing effect on the buffer 41.

[0055] Specifically, in this embodiment, the buffer member 41 can be configured as a spring, a tension spring or other elastic structure, which is not limited here.

[0056] In this embodiment, the nozzle mechanism includes at least a nozzle and a return spring. The elastic force of the buffer 41 is greater than the elastic force of the return spring, thereby preventing the nozzle from being unable to be pressed downward due to the inability to be compressed by the return spring.

[0057] Please also refer to Figures 1 to 5 In this embodiment, the driving assembly 1 includes a driving member 11, a rotating member and a follower 13. The rotating member is connected to the output shaft 111 of the driving member 11. The follower 13 is fixed to the transmission seat 2. The rotating member can be in contact with the follower 13. The driving member 11 can drive the rotating member to rotate. When the rotating member rotates, it can drive the follower 13 to move downward, thereby driving the transmission seat 2 to move downward.

[0058] Specifically, see Figure 5In this embodiment, the rotating member is configured as a cam 12, and the follower 13 is configured as a roller. The cam 12 is connected to the output shaft 111 of the driving member 11, and the roller is horizontally fixed on the second protrusion 22, and the cam 12 is located at the top of the roller. The cam 12 is rotationally connected to the roller, and the cam 12 rotates under the drive of the driving member 11 to contact and connect with the roller, thereby realizing the downward pushing action of the roller, and the downward movement of the roller can drive the transmission seat 2 to move downward.

[0059] Specifically, in this embodiment, the driving member 11 can be configured as a motor, which is not limited here.

[0060] For further information, see Figure 5 In this embodiment, the driving assembly 1 further includes a fixing plate 14 and a bearing 15.

When the output shaft 111 of the driving member 11 rotates, the output shaft 111 drives the cam 12 to rotate. At this time, the bearing 15 also rotates with the cam 12, thereby improving the flexibility of the rotation of the cam 12.

[0061] Please also refer to Figure 3 and Figure 4 In this embodiment, the protection mechanism 100 further includes a fixing frame 6 and a second slider 7. The second slider 7 is fixed on the transmission seat 2, and the first slider 31 and the second slider 7 are respectively located on two opposite sides of the transmission seat 2.

The fixing frame 6 is provided with a second slide rail 61, and the second slider 7 is slidably disposed on the second slide rail 61. When the driving assembly 1 drives the transmission seat 2 to move downward, the transmission seat 2 drives the second slider 7 to slide downward on the second slide rail 61, thereby improving the balance of the movement of the transmission seat 2.

[0062] Specifically, in this embodiment, the fixing frame 6 is used to fix the protection mechanism 100 as a whole to the outside.

[0063] Please also refer to Figures 1 to 3In this embodiment, the protection mechanism 100 further includes a reset assembly 8, which includes an elastic member 81 and a second guide member 82. The second guide member 82 is fixed to the transmission seat 2, and a guard plate 62 is extended and fixed on the fixed frame 6. The elastic member 81 abuts between the second guide member 82 and the guard plate 62. When the cam 12 of the driving assembly 1 squeezes the roller downward, the transmission seat 2 moves downward under the drive of the roller, thereby realizing the downward pressing operation of the suction nozzle mechanism. At this time, the elastic member 81 is in a stretched state. When the cam 12 rotates to a state where the roller is not squeezed, the elastic member 81 resets to push the transmission seat 2 to move upward, thereby realizing the reset action of the suction nozzle mechanism. Moreover, when the elastic member 81 resets, it can push the transmission seat 2 to move upward, and the sliding assembly 3 and the first sensing member 52 move upward at the same time to realize the reset work. Therefore, the elastic member 81 can realize the upward reset work of the protection mechanism 100.

The second sensing member 55 can detect the second sensing sheet 54 and obtain the position of the transmission seat 2 through the second sensing sheet 54, so as to know whether the nozzle mechanism and the sliding assembly 3 are in a downwardly pressed state, thereby ensuring that the end of the nozzle mechanism can be close to the electronic components, which is conducive to the accurate positioning of the nozzle mechanism and the sliding assembly 3.

[0067] Specifically, in this embodiment, the second sensing element 55 is configured as a photoelectric sensor, an infrared sensor, or other sensors, which are not limited here.

[0068] For details, please refer to Figure 1 and Figure 3 In this embodiment, the sensing component 5 also includes a second bracket 56 and an adjustment plate 57. The second bracket 56 is fixed on the fixing frame 6, the adjustment plate 57 is fixed on one side of the second bracket 56, and the sensing element is fixed on one side of the adjustment plate 57. The adjustment plate 57 is used to adjust the height of the sensing element according to demand.

[0069] The present invention further provides a material picking device, including a nozzle mechanism and a protection mechanism 100, wherein the nozzle mechanism is used to pick up electronic components. The protection mechanism 100 here is the same as the above-mentioned protection mechanism 100, and will not be described in detail here.

[0070] Specifically, the nozzle mechanism is disposed at the bottom of the transmission base 2 , and the elastic force of the spring of the nozzle mechanism is smaller than that of the buffer 41 .

[0071] The material picking device of the present invention adopts the above setting of the protection mechanism 100, so that when the overall device makes a misjudgment and squeezes or overlaps the electronic components, the sliding component 3 can contact the electronic components and squeeze the buffer component 4 to slide in the opposite direction. At this time, the sensing component 5 controls the alarm to alarm, avoiding the suction nozzle mechanism from continuing to move and damaging the electronic components, thereby strengthening the protection of the electronic components and improving the productivity of the electronic components.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
