[0025] For the convenience of understanding the present utility model, the present utility model will be described more comprehensively below. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present utility model more thorough and comprehensive.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0027] Please refer to Figures 1 to 8, which is a tray feeding mechanism provided by an embodiment of the utility model, is used for transferring material 10; in this embodiment, the material 10 is a chip; the tray feeding mechanism includes a tray 20 for supporting the material 10, a base 30, a transfer assembly 40 slidably mounted on the base 30, and a lifting assembly 50 mounted on the base 30 and connected to the tray 20; the base 30 includes a slide rail 41; the transfer assembly 40 includes a sliding seat 42 slidably mounted on the slide rail 41 and a transfer base 43 mounted on the sliding seat 42; the lifting assembly 50 is used to drive the tray 20 to rise or fall; when the tray 20 is raised by the lifting assembly 50, the sliding seat 42 drives the transfer base 43 to slide to the bottom of the tray 20; when the tray 20 is lowered by the lifting assembly 50 into the transfer base 43, the sliding seat 42 drives the tray 20 and the material 10 to slide away from the base 30.

[0028] First, the material 10 is placed on the tray 20 on the transfer base 43; when the material 10 needs to be transferred, the sliding seat 42 is manually pushed to make the sliding seat 42 slide along the slide rail 41, drive the transfer base 43 to move, and the transfer base 43 moves to the lifting assembly 50; then, the lifting assembly 50 is started, and the lifting assembly 50 is located on the base 30 in the middle of the slide rail 41 and lifts upward; because the tray 20 is set on the transfer base 43 opposite to the lifting assembly 50, the lifting assembly 50 will lift the tray 20 and the material 10 thereon and make them leave their original position when lifting; at this time, the sliding seat 42 is manually pulled back to make the sliding seat 42 slide in the opposite direction along the slide rail 41, and the transfer base 43 is transferred to a place away from the base 3 0, and then the supporting tray 20 is lowered downward by the lifting component 50 so that the supporting tray 20 is placed on the base 30; after the material 10 on the supporting tray 20 is consumed, the lifting component 50 lifts the supporting tray 20 upward again, and manually pushes the sliding seat 42, and the transfer base 43 is transferred to the base 30 opposite to the supporting tray 20 through the cooperation of the sliding seat 42 and the slide rail 41, and the supporting tray 20 is lowered downward with the lifting component 50, so that the supporting tray 20 falls on the transfer base 43; finally, the sliding seat 42 is manually pulled back, so that the sliding seat 42 and the slide rail 41 cooperate to transfer the transfer base 43 from the base 30 on one side of the lifting component 50 to the base 30 away from the side of the transfer component 40, so as to realize the transfer of the material 10.

[0029] The tray feeding mechanism, through the cooperation of the slide rail 41 and the sliding seat 42, can ensure that the transfer base 43 moves smoothly without jamming, reducing the uneven movement caused by friction or resistance, making the transfer process of the bearing tray 20 more stable and avoiding damage to the material 10 due to vibration; through the lifting assembly 50, the bearing tray 20 and the material 10 can be lifted to achieve precise displacement control in the vertical direction, ensuring the accurate position adjustment of the material 10 in the vertical direction; the transfer base 43 and the base 30 provide a stable support and moving platform for the bearing tray 20 and the material 10, ensuring the smoothness of the material 10 during the transfer process.

[0030] Please refer to Figures 1 to 4 , the lifting assembly 50 includes a linear motor 51 and a lifting seat 52. The housing of the linear motor 51 is fixed to the bottom of the base 30, and the lead screw of the linear motor 51 penetrates through the base 30 and is threadedly connected to the lifting seat 52. The housing of the linear motor 51 is fixed to the bottom of the base 30 to maintain a stable position; since the lead screw penetrates through the base 30 and is threadedly connected to the lifting seat 52, the rotational motion of the lead screw will be converted into the linear motion of the lifting seat 52; when the lead screw rotates clockwise, the lifting seat 52 will move upward along the lead screw to achieve the lifting action; when the lead screw rotates counterclockwise, the lifting seat 52 will move downward along the lead screw to achieve the lowering action; the linear motor 51 can provide linear motion control, enabling the lifting height of the lifting seat to be precisely adjusted to meet the requirements for the lifting position.

[0031] The tray feeding mechanism further includes a guiding mechanism 60, and the guiding mechanism 60 includes a fixed block 61 and a guiding column 62; the fixed block 61 is fixedly installed on the base 30, and the guiding column 62 penetrates through the base 30 and the fixed block 61 and is connected to the lifting seat 52. When the lifting assembly 50 performs the lifting action, during the upward or downward movement of the lifting seat 52, the guiding column 62 plays a role in guiding and restricting the movement direction; since the guiding column 62 penetrates through the base 30 and the fixed block 61 and is connected to the lifting seat 52, the lifting seat 52 moves along the axis direction of the guiding column 62, thus ensuring the linearity and stability of the movement of the lifting seat 52; preventing the lifting seat 52 from deviating, shaking or rotating during the lifting process, ensuring the accuracy and reliability of the lifting action.

[0032] The jacking assembly 50 further includes a guiding sleeve 53 which is sleeved on the guiding column 62 and installed at the bottom of the base 30. When the guiding column 62 performs telescopic movement, the guiding sleeve 53 provides additional support and guidance for the guiding column 62. Since the guiding sleeve 53 is sleeved on the guiding column 62 and installed at the bottom of the base 30, it can limit the radial shaking and offset of the guiding column 62 during the telescopic process, making the movement of the guiding column 62 smoother and more linear. The cooperation between the guiding sleeve 53 and the guiding column 62 can reduce the direct friction between the guiding column 62 and the base 30, reduce wear, and also help to maintain the perpendicularity of the guiding column 62, further ensuring the accuracy and reliability of the jacking action.

[0033] A jacking limit block 54 is provided at the bottom end of the guiding column 62. When the guiding column 62 moves upward, the jacking limit block 54 will move along with the guiding column 62. When the guiding column 62 rises to a predetermined limit position, the jacking limit block 54 will touch the guiding sleeve 53 to prevent the jacking limit block 54 from rising further, thereby restricting the further upward movement of the guiding column 62 and ensuring that the guiding column 62 does not exceed the safe or design - allowed jacking height range. It effectively avoids equipment damage, material 10 dropping or other possible safety accidents and operation errors caused by excessive jacking.

[0034] Please refer to Figure 5 and Figure 6 As shown in [relevant figure], a jacking fixing seat 55 is provided on one side of the guiding column 62, and the jacking fixing seat 55 is installed on the end face at the bottom of the base 30. Photoelectric sensors 56 are respectively installed at the upper and lower ends of the jacking fixing seat 55. When the guiding column 62 performs jacking or lowering movement, as the position of the guiding column 62 changes, it will pass by the photoelectric sensors 56 installed at the upper and lower ends of the jacking fixing seat 55. The photoelectric sensors 56 detect the position of the guiding column 62 by emitting and receiving light. When the guiding column 62 blocks the light, the photoelectric sensors 56 will generate corresponding electrical signals. The triggering of the upper photoelectric sensor 56 indicates that the guiding column 62 has risen to a position close to the upper limit, and the triggering of the lower photoelectric sensor 56 indicates that the guiding column 62 has descended to a position close to the lower limit. To judge the position state of the guiding column 62 and control the movement of the jacking assembly 50 accordingly, stop the jacking or lowering action in time to prevent the guiding column 62 from exceeding the safe range or not reaching the predetermined working position. It can detect the upper and lower limit positions of the guiding column 62 in real - time and accurately, achieve precise control of the jacking height, ensure that each jacking operation can reach the predetermined position requirements, effectively prevent the guiding column 62 from excessive jacking or lowering, avoid safety accidents such as equipment damage and material 10 dropping caused by over - travel, and improve the operation safety of the entire system.

[0035] The photoelectric induction component 56 includes a U-shaped induction arm 560 and an alarm 561. The induction arm 560 is fixedly installed on the jacking fixing seat 55, and the alarm 561 is installed on the induction arm 560. A convex block 57 extends from one side of the jacking fixing seat 55 to the side of the induction arm 560. The convex block 57 includes a fixing portion 570 fixedly installed on the jacking fixing seat 55 and a protruding portion 571 extending into the induction arm 560. When the guide post 62 moves, the convex block 57 on one side of the jacking fixing seat 55 moves along with the jacking fixing seat 55. When the protruding portion 571 of the convex block 57 enters the U-shaped induction arm 560, the light propagation inside the induction arm 560 will be blocked. At this time, the induction arm 560 will detect the change in light and transmit this signal to the alarm 561. After receiving the signal, the alarm 561 will give an alarm, indicating that the position of the guide post 62 has reached a specific warning position. The cooperation between the U-shaped induction arm 560 and the convex block 57 can accurately detect the position of the guide post 62, ensure the accuracy of position judgment, and reduce errors. Through the alarm 561, an alarm can be issued in time when the guide post 62 approaches the limit position, enabling the operator to be aware in advance and have enough time to react to avoid dangerous situations.

[0036] Please refer to Figure 7 and Figure 8 , the transfer base 43 includes four transfer bottom blocks 430 and a transfer bracket 531. The four transfer bottom blocks 430 are respectively fixed on the sliding seats 42 on both sides. The transfer bottom blocks 430 are connected to the transfer bracket 531, and the four transfer brackets 531 cooperate with the four corners of the support tray 20. In this embodiment, the four corners of the support tray 20 are right angles. In another embodiment, the four corners of the support tray 20 can also be arc-shaped. When the sliding seat 42 slides on the slide rail 41, it drives the four transfer bottom blocks 430 fixed on it to move. Since the transfer bottom blocks 430 are connected to the transfer bracket 531, the movement of the transfer bottom blocks 430 will drive the transfer bracket 531 to move together. The four transfer brackets 531 respectively cooperate with the four corners of the support tray 20, so that the support tray 20 can be stably driven to move when the transfer bracket 531 moves. The four transfer bottom blocks 430 and the transfer bracket 531 respectively support the four corners of the support tray 20, which can evenly share the weight of the support tray 20 and the material 10, make the transfer process more stable, and reduce the risk of the material 10 shaking and falling. Since the four corners of the support tray 20 are independently supported and controlled, even if the material 10 is unevenly distributed, the balance of the support tray 20 can be better maintained and tilting can be avoided.

[0037] A limiting step 532 for carrying and fixing the bearing tray 20 is provided at the connection between the transfer bottom block 430 and the transfer bracket 531. When the transfer bracket 531 is connected to the transfer bottom block 430, the limiting step 532 plays a clear positioning and supporting role; when the bearing tray 20 is placed on the transfer bracket 531, the limiting step 532 can limit the movement of the bearing tray 20 in the horizontal direction, preventing it from slipping or shifting; at the same time, the limiting step 532 also bears part of the weight of the bearing tray 20, enabling the bearing tray 20 to be more stably placed on the transfer base 43.

[0038] The transfer bracket 531 and the sliding seat 42 on the side away from the base 30 are respectively connected and fixed by a first connecting cross bar 433 and a second connecting cross bar 434; a connecting plate 435 is provided on one side of the first connecting cross bar 433 and the second connecting cross bar 434, and the connecting plate 435 is respectively connected and fixed to the first connecting cross bar 433 and the second connecting cross bar 434 through a connecting rod 436. When the sliding seat 42 slides on the slide rail 41, it will drive the second connecting cross bar 434 connected to it to move; since the second connecting cross bar 434 is connected and fixed to the first connecting cross bar 433 through the connecting plate 435, the first connecting cross bar 433 will also move accordingly; and the first connecting cross bar 433 is connected to the transfer bracket 531 on the side away from the base 30, so the transfer bracket 531 will move together, thus realizing the smooth movement of the entire transfer base 43; the connecting plate 435 plays a role in strengthening the connection and transmitting force, ensuring that the first connecting cross bar 433 and the second connecting cross bar 434 can move in coordination, so that each part of the transfer base 43 can move synchronously.

[0039] The above embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
