Description

Technical Field

[0001] This utility model relates to the technical field of tray loading and unloading devices, and in particular to a tray loading and unloading device. Background Technology

[0002] In fields such as electronics manufacturing and precision instrument assembly, trays serve as standardized containers for carrying small components (such as chips, connectors, and sensors). Automated loading and unloading operations are crucial for improving production efficiency and reducing manual intervention. Currently, the tray loading and unloading devices commonly used in the industry typically include a hopper for storing stacked trays, a lifting mechanism for driving the trays up and down, and a handling mechanism for grabbing or transferring trays. However, existing material hoppers are mostly fixed structures with closed tops or bottoms and only pre-reserved openings for loading and unloading. During loading operations, operators need to vertically insert stacked trays from the top opening of the hopper or replenish them through a pull-out structure at the bottom. This is inconvenient for operators to put stacked trays into the hopper when it is high, and it is also easy for the trays to tilt and components to fall off due to unstable operation. On the other hand, the bottom pull-out structure occupies a lot of space, and the disassembly and assembly process is cumbersome when changing the hopper or cleaning internal impurities, which affects the loading and unloading efficiency of trays. Therefore, improvements are necessary. Utility Model Content The purpose of this invention is to provide a tray loading and unloading device, which has the advantages of simple structure and convenient tray loading and unloading.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] Example: refer to Figures 1 to 6A tray loading and unloading device includes a base 1 and a loading / unloading screw slide 2 fixedly connected to the base 1. At least one storage bin 3 for storing full trays and one unloading bin 4 for storing empty trays are fixedly connected to the base 1. A lifting and unloading assembly 5 is fixedly connected to the sliding end of the loading / unloading screw slide 2. The loading / unloading screw slide 2 drives the lifting and unloading assembly 5 to move, thereby retrieving a tray containing parts from the storage bin 3 and transporting it to a parts loading station. When all parts are retrieved from the tray, the loading / unloading screw slide 2 transports the empty tray to the unloading bin 4 for storage. Both the storage bin 3 and the unloading bin 4 include components fixedly connected to the base 1 along the tray... The tray positioning and fixing seat 6 on one side of the tray loading and unloading direction and the tray positioning rotating seat 8 based on the pin rotating assembly 7 are rotatably connected to the other side of the base 1, thereby opening the storage bin 3 and the unloading bin 4 to realize the tray loading and unloading. The tray positioning rotating seat 8 is controlled by the pin rotating assembly 7 to rotate, so that the storage bin 3 and the unloading bin 4 can be opened from the side. Thus, during the loading and unloading process, the stacked trays can be placed or taken out directly from the side without lifting from the top or pulling from the bottom, which greatly improves the convenience of tray loading and unloading. In this embodiment, two sets of storage bins 3 are arranged side by side on the base 1. When the trays in one set of storage bins 3 are taken out and need to be loaded, the lifting and unloading assembly 5 can take out materials from the other set of storage bins 3, thereby avoiding tray loading intervals and ensuring tray loading efficiency.

[0016] refer to Figure 3 Specifically, the lifting and loading assembly 5 includes a lifting cylinder 51 fixedly connected to the sliding end of the loading and unloading screw slide 2 along the vertical direction, and a loading and unloading seat 52 fixedly connected to the lifting end of the lifting cylinder 51 for abutting the bottom surface of the tray to support the tray. When loading material from the storage bin 3 or the unloading bin 4, the lifting cylinder 51 drives the loading and unloading seat 52 to rise and abut against the bottom surface of the tray.

[0017] refer to Figures 4 to 6 Specifically, the storage bin 3 and the unloading bin 4 include a support frame 31 symmetrically fixedly connected to the base 1 along the tray loading and unloading direction. The tray positioning fixing seat 6 and the tray positioning rotating seat 8 are set on the support frame 31. The storage bin 3 is fixedly connected to the support frame 31 with an abutment support component 32 for abutting the two sides of the tray to support the tray. The unloading bin 4 is fixedly connected to the support frame 31 with a limiting support component 41 for supporting the bottom sides of the tray to restrict the movement of the empty tray. Through the abutment support component 32 and the limiting support component 41, the stacked trays are respectively supported in the storage bin 3 and the unloading bin 4, and the trays can pass through when the lifting and unloading component 5 picks up and unloads materials.

[0018] refer to Figure 2 Specifically, the pin-rotating assembly 7 includes rotating seats 71 symmetrically fixedly connected to both ends of the support frame 31. A tray positioning rotating seat 8 is rotatably connected to the rotating seats 71 based on a rotating shaft 72. A fixed pin 73 is slidably connected to the rotating seats 71. A pin hole is provided on the tray positioning rotating seat 8. A limit stop 74 is also fixedly connected to the side of the tray positioning rotating seat 8 facing the rotation direction. When it is necessary to open the storage bin 3 or the unloading bin 4 for tray loading or unloading, the fixed pin 73 is pulled out from the pin hole, and the tray positioning rotating seat 8 is rotated until the limit stop 74 abuts against the support frame 31. Then, stacked trays can be placed into the storage bin 3 from the opened side, or stacked empty trays can be taken out from the unloading bin 4. This improves the convenience of tray loading and unloading while avoiding tray tilting and component detachment due to height limitations, significantly improving the tray loading and unloading efficiency. The efficiency of loading and unloading the tray is monitored by a contact sensor 75 fixedly connected to the rotating seat 71 for detecting the tray positioning rotating seat 8. After the tray is loaded and unloaded, the tray positioning rotating seat 8 is rotated and the fixing pin 73 is inserted into the pin hole to complete the reset of the tray positioning rotating seat 8. The contact sensor 75 can detect whether the tray positioning rotating seat 8 has been reset.

[0019] refer to Figure 4 Specifically, the abutment support assembly 32 includes a lifting cylinder 321 fixedly connected vertically to the support frame 31 and a lifting platform 322 fixedly connected to the lifting end of the lifting cylinder 321. A sliding abutment block 323 for abutting the side wall of the tray is slidably connected horizontally on the lifting platform 322. Several support blocks 324 for supporting the edge of the tray are evenly spaced and fixedly connected to the sliding abutment block 323. A horizontal abutment cylinder 325 for driving the sliding abutment block 323 to slide is fixedly connected to the lifting platform 322. When material is retrieved from the storage bin 3, the loading / unloading screw slide 2 drives the lifting and unloading assembly 5 to move to the bottom of the storage bin 3. The lifting cylinder 51 drives the unloading seat 52 to rise and support the bottom tray. The tray, the horizontal abutment cylinder 325 of the abutment support component 32 drives the sliding abutment block 323 to retract, the lifting cylinder 321 drives the upper tray to rise to avoid, and after the material pick-and-place seat 52 descends, the tray is transferred to the part loading station by the loading and unloading screw slide table 2.

[0020] refer to Figures 5 to 6Specifically, the limiting support assembly 41 includes a horizontal fixed seat 411 fixedly connected to the support frame 31 along the horizontal direction and several mounting seats 412 fixedly connected to the horizontal fixed seat 411 at even intervals. A rotating support block 413 for supporting the bottom of the tray is rotatably connected to the mounting seat 412 based on a torsion spring. An inclined abutment surface 414 is provided at the bottom of the rotating support block 413. A limiting block 415 for limiting the rotating support block 413 is fixedly connected to the mounting seat 412. When empty trays are recycled, the loading and unloading screw slide 2 drives the lifting and unloading assembly 5 to move to the bottom of the unloading bin 4. The lifting cylinder 51 drives the unloading seat 52 and the empty tray to rise to squeeze the rotating support block 413 of the limiting support assembly 41. The edge of the empty tray abuts the inclined abutment surface 414, thereby driving the rotating support block 413 to rotate upward. The torsion spring is compressed. The rear torsion spring drives the rotating support block 413 to reset and support the bottom of the empty tray, realizing the stacking and unloading of empty trays.

[0021] Brief description of the usage process: First, when loading materials, pull out the fixing pin 73 in the pin rotating assembly 7, rotate the material tray positioning rotating seat 8 around the rotating shaft 72 to open the side of the storage bin 3, place the stacked full trays, reset the material tray positioning rotating seat 8, insert the fixing pin 73 to complete the fixation, and after the contact sensor 75 detects the position, the abutment support assembly 32 of the storage bin 3 is activated. The horizontal abutment cylinder 325 drives the sliding abutment block 323 to make the support block 324 abut against the edge of the tray to achieve support. The lifting cylinder 321 drives the tray to rise and fall according to the material picking requirements. When picking up materials from the tray, the loading and unloading screw slide 2 drives the lifting and picking assembly 5 to move below the storage bin 3, and the lifting cylinder 51 drives the picking and picking seat 52 to rise to support the bottom tray. The tray, the horizontal abutment cylinder 325 of the abutment support component 32 drives the sliding abutment block 323 to retract, the lifting cylinder 321 drives the upper tray to rise to avoid, and after the pick-and-place seat 52 descends, the loading and unloading screw slide 2 moves the tray to the parts loading station. When the parts in the tray are taken out and the empty tray needs to be recycled, the loading and unloading screw slide 2 drives the lifting pick-and-place component 5 to move to the bottom of the unloading bin 4. The lifting cylinder 51 drives the pick-and-place seat 52 and the empty tray to rise to squeeze the rotating support block 413 of the limiting support component 41. The edge of the empty tray abuts the inclined abutment surface 414, thereby driving the rotating support block 413 to rotate upward. The torsion spring is compressed, and the rear torsion spring drives the rotating support block 413 to reset and support the bottom of the empty tray, realizing the stacking and unloading of empty trays.
