Technical Field
[0001] This utility model applies to the field of automated production line equipment technology and provides an automatic terminal tray feeding device. Background Technology
[0002] In electronic product manufacturing lines, robots or robotic arms are typically used to pick up and transfer parts. Electronic products usually have a large number of tiny parts, and terminal parts are one of the most frequently used small parts in electronic product manufacturing. To facilitate the identification and gripping of terminal parts by robotic arms, they are usually placed on special trays. These trays have limiting grooves that mimic the shape of the terminal parts. Placing the terminal parts one by one into the limiting grooves will limit their position and shape. Usually, these trays are first manually placed with the terminal parts, and then manually placed onto the conveyor belt of the production line. However, because the efficiency of manually placing parts is too low, it often cannot keep up with the material supply demand of the production line. At the same time, manual placement is also more expensive, and misalignment is prone to occur when placing the trays. Utility Model Content
[0003] To address this, the present invention provides an automatic terminal tray feeding device. Terminal trays are stacked sequentially from top to bottom within a tray storage chamber formed by four tray supports. The bottommost terminal tray is supported by a tray support device below. The tray storage chamber is located above the tray transfer conveyor belt. When a terminal tray needs to be supplied to the tray transfer conveyor belt, the bottommost terminal tray is moved downwards, while the second to last terminal tray and the terminal trays above it remain supported in the tray storage chamber by a tray separating device. This allows for the centralized storage of multiple terminal trays and the automatic feeding of individual trays.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic terminal tray feeding device, comprising:
[0005] The equipment base plate is used to install various components;
[0006] At least four tray supports are arranged in a rectangular array. The space enclosed by the four tray supports is a tray storage compartment for storing terminal trays. A tray separating device is provided at the bottom of the tray supports. The tray separating device includes a tray separating telescopic block and a tray separating drive mechanism. The tray separating drive mechanism is drivenly connected to the tray separating telescopic block.
[0007] The material tray transfer conveyor belt is fixedly installed above the equipment base plate and is used to transfer terminal material trays from the material tray storage bin.
[0008] The material tray support device includes a bottom support plate lifting mechanism and a material tray bottom support plate, wherein the bottom support plate lifting mechanism is drivenly connected to the material tray bottom support plate.
[0009] Furthermore, it also includes two tray placement guide devices, which are respectively set on both sides of the tray transfer conveyor belt. Each tray placement guide device includes a limit post mounting plate and a mounting plate lifting mechanism. The mounting plate lifting mechanism is drivenly connected to the limit post mounting plate to drive the limit post mounting plate to lift. Several tray bottom limit posts that are adapted to the bottom surface structure of the terminal tray are fixedly set at the upper end of the limit post mounting plate.
[0010] Furthermore, it also includes a tray sensing device, which is located at the bottom of one of the four tray supports, and the tray sensing device includes at least one photoelectric sensor switch.
[0011] Furthermore, the material tray sensing device has two photoelectric sensors, one of which is positioned below the upper surface of the tray telescopic block, and the other is positioned above the upper surface of the tray telescopic block.
[0012] Furthermore, it also includes a micro switch, which is equipped with a switch trigger spring, and the switch trigger spring is located near the lower edge of the material storage bin.
[0013] Furthermore, there are two material tray transfer conveyor belts, which are set parallel to each other at the same height. There are three material tray bottom support plates, one of which is set between the two material tray transfer conveyor belts, and the remaining two are set on both sides of the two material tray transfer conveyor belts respectively.
[0014] Furthermore, the tray support includes two vertically arranged tray limiting plates, and the two tray limiting plates of the same tray support are respectively adapted to the two adjacent side walls of the terminal tray.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. In the present invention, a material tray storage bin consisting of four material tray supports is set above the material tray transfer conveyor belt. Several terminal material trays are stacked in the material tray storage bin. The terminal material trays are controlled to descend by a material tray support device. At the same time, when the bottom layer of terminal material trays is unloaded, a tray separating device is inserted between the bottom layer of terminal material trays and the second to last layer of terminal material trays, so that one terminal material tray descends at a time, thus completing the automated feeding of terminal material trays.
[0017] 2. Add a tray placement guide device. During the process of transferring a single terminal tray to the tray conveyor belt, several tray bottom limit posts of the tray placement guide device are locked on the lower end face of the terminal tray, so that the terminal tray can always be placed in the correct position during the descent.

[0037] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0038] Examples, examples, refer to the appendix Figure 1 This utility model provides an automatic terminal tray feeding device, including a device fixing base plate 100 for mounting various components, a tray transfer conveyor belt 200 fixedly mounted above the device fixing base plate 100, and four tray supports 300 arranged in a rectangular array above the tray transfer conveyor belt 200. The space enclosed by the four tray supports 300 is a tray storage compartment for storing terminal trays 800. The terminal trays 800 are stacked and stored in the tray storage compartment from top to bottom, as shown in the attached figure. Figure 4 As shown, the tray support 300 includes two vertically arranged tray limiting plates 310. The two tray limiting plates 310 of the same tray support 300 are respectively adapted to two adjacent side walls of the terminal tray 800. In this way, the four tray supports 300 can respectively limit the four corners of the terminal tray 800. The purpose of the automatic terminal tray feeding device in this embodiment is to transfer one of the terminal trays 800 stored in the tray storage bin to the tray transfer conveyor belt 200 when needed, and then transport it to the required usage position through the tray transfer conveyor belt 200. A tray support device 600 is also provided below the tray storage bin, as shown in the attached figure. Figure 7As shown, the tray support device 600 includes a bottom tray lifting mechanism 610 and a tray bottom tray 620. The bottom tray lifting mechanism 610 is driven to connect with the tray bottom tray 620. The tray bottom tray 620 can support the stacked terminal trays 800 from below, and then lift them by the bottom tray lifting mechanism 610. During the lifting process, the lowest terminal tray 800 is transferred to the tray transfer conveyor belt 200. In this embodiment, to ensure stability, the number of tray transfer conveyor belts 200 is set to two, and the two tray transfer conveyor belts 200 are set parallel and at the same height. The number of tray bottom trays 620 is set to three, one of which is set on the two tray transfer conveyor belts 200. Between 00 and 00, the remaining two tray base plates 620 are respectively set on both sides of the two tray transfer conveyor belts 200. This structure can ensure the stability of supporting the terminal tray 800. After transferring the terminal tray 800 to the tray transfer conveyor belt 200, the tray base plate 620 can retract under the tray transfer conveyor belt 200 to avoid affecting the transportation of the terminal tray 800. Since only the bottommost terminal tray 800 needs to be lowered onto the tray transfer conveyor belt 200 at a time, it is necessary to separate the bottommost terminal tray 800 from the other terminal trays 800 during the loading process. Therefore, a tray separating device 400 is set at the bottom of each tray support 300, as shown in the attached figure. Figure 5 As shown, the tray splitting device 400 includes a tray splitting telescopic block 410 and a tray splitting drive mechanism 420. The tray splitting drive mechanism 420 is drive-connected to the tray splitting telescopic block 410, as shown in the attached figure. Figure 6 As shown, during the loading process of the bottommost terminal tray 800, the tray-separating telescopic block 410 pops out to the bottom of the second-to-last terminal tray 800. The tray-separating device 400 of the four tray supports 300 can separate the bottommost terminal tray 800 from the other terminal trays 800 during loading. Simultaneously, it can also support the remaining terminal trays 800 in place of the tray support device 600 during the loading process. However, because the terminal tray is in an indefinite position after leaving the tray storage bin while being loaded onto the tray transfer conveyor belt 200 by the tray bottom support plate 620, this may cause the terminal tray 800 to deviate when it finally falls onto the tray transfer conveyor belt 200. Therefore, a tray placement guide device 700 is installed on each side of the tray transfer conveyor belt 200, as shown in the attached diagram. Figure 9As shown, the tray placement guide device 700 includes a limiting post mounting plate 720 and a mounting plate lifting mechanism 710. The mounting plate lifting mechanism 710 is driven to connect with the limiting post mounting plate 720 to drive the limiting post mounting plate 720 to lift. Several tray bottom limiting posts 730 adapted to the bottom structure of the terminal tray 800 are fixedly provided on the upper end of the limiting post mounting plate 720. During the process of the tray bottom support plate 620 supporting the bottom terminal tray 800 to the tray transfer conveyor belt 200 for feeding, the tray bottom limiting posts 730 can be inserted upward into the holes and grooves at the bottom of the terminal tray 800 to fix the position of the terminal tray 800 in the preset direction, thus ensuring the accuracy of placement.
[0039] Meanwhile, for the coordination between the various components, as shown in the attached document... Figure 5 As shown, a tray sensing device 500 is installed at the bottom of one of the four tray supports 300. The tray sensing device 500 includes two photoelectric sensors 510. One photoelectric sensor 510 is positioned below the upper surface of the tray extension block 410, and the other photoelectric sensor 510 is positioned above the upper surface of the tray extension block 410. The upper photoelectric sensor 510 is used to detect the number of terminal trays 800 in the tray storage compartment, while the lower photoelectric sensor 510 is used to detect the terminal trays 800 being loaded. A micro switch 900 is also provided, as shown in the attached diagram. Figure 8 As shown, the micro switch 900 is equipped with a switch trigger spring 910, which is located near the lower edge of the material storage compartment. When the switch trigger spring 910 is pressed, the micro switch 900 is triggered. The micro switch 900 is linked with the tray separating device 400. When the terminal material tray 800 is fed and passes the switch trigger spring 910, the micro switch 900 is triggered. At this time, the tray separating telescopic block 410 of the tray separating device 400 will extend to isolate the bottom terminal material tray 800 being fed from other terminal material trays 800.
[0040] The working principle of this embodiment is as follows:
[0041] The automatic terminal tray feeding device in this embodiment has two working states:
[0042] Working status 1: Non-material loading stage, as shown in the attached document. Figure 2 As shown, at this time, the tray bottom support plate 620 is located at the bottom of the tray storage bin. The three tray bottom support plates 620 support the several terminal trays 800 stacked in the tray storage bin. The tray bottom support plate 620 can provide stable support for the terminal trays 800.
[0043] Working state two: Material loading stage, as shown in the attached document. Figure 3As shown, at this time, the bottommost terminal tray 800 stored in the tray storage bin needs to be transferred to the tray transfer conveyor belt 200. The specific process is as follows: First, the tray bottom support plate 620 drives all the terminal trays 800 to descend under the drive of the bottom support plate lifting mechanism 610. When the bottommost terminal tray 800 contacts the switch trigger spring 910 downwards, thereby triggering the micro switch 900, the tray splitting telescopic block 410 of the tray splitting device 400 extends to below the second-to-last terminal tray 800 under the drive of the tray splitting drive mechanism 420. At this time, the tray bottom support plate 620 drives the bottommost terminal tray 800 to continue to descend, while the remaining terminal trays 800 are supported in the tray storage bin by the four tray splitting telescopic blocks 410. At the same time, before the bottommost terminal tray 800 leaves the tray storage bin, the tray bottom limiting post 730 of the two tray placement guide devices 700 will be locked upwards into the bottommost terminal tray 800. Within the slots and other mechanisms on the lower end face of 00, the bottommost terminal tray 800 is limited. At this time, the bottom limiting post 730 and the bottom support plate 620 of the tray simultaneously drive the bottommost terminal tray 800 to descend until it is placed on the tray transfer conveyor belt 200. Then, the bottom limiting post 730 and the bottom support plate 620 continue to descend, eventually disengaging from the bottommost terminal tray 800. The bottommost terminal tray 800 then leaves under the drive of the tray transfer conveyor belt 200. After the bottommost terminal tray 800 leaves, the bottom limiting post 730 resets, and the bottom support plate 620 rises again to abut against the new bottommost terminal tray 800 (i.e., the previous penultimate terminal tray 800) in the tray storage bin. Then, the tray extension block 410 retracts, and the device returns to the non-loading stage, waiting for the next loading stage.
