Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent manufacturing, in particular to an automatic electronic tray unloading device. BACKGROUND

[0002] An electronic tray is a tray containing electronic components such as capacitors and resistors. In order to facilitate management and unloading, electronic components of different types and specifications are packaged in different electronic trays. Electronic trays come in various sizes such as 7 inches and 13 inches. In the production and management process of electronic components, automatic detection equipment and automatic labeling equipment are required. However, the automatic inspection equipment and automatic labeling equipment for electronic trays can usually only inspect or label one size of electronic tray. If different sizes of electronic trays are to be compatible, different sizes of jigs need to be set according to the size of the electronic tray, and different jigs need to be updated according to the size of the electronic tray during use.

[0003] When unloading electronic trays, the unloading equipment is provided with multiple unloading positions, and the unloading equipment needs to place electronic trays of different sizes on different unloading positions according to rules. In this case, multiple jigs of different sizes need to be customized for the unloading equipment, and different size jigs need to be frequently replaced, thus greatly increasing the equipment investment cost and reducing the unloading efficiency. SUMMARY

[0004] In view of the above problems, the present application provides an automatic electronic tray unloading device and unloading method to solve the technical problems of the above electronic tray needing to customize different jigs, high investment cost and low use efficiency.

[0005] To achieve the above purpose, the inventors provide an automatic electronic tray unloading device, which comprises:

[0006] a grabbing mechanism for grabbing electronic trays;

[0007] a receiving mechanism comprising two or more parallelly arranged string guide shafts;

[0008] a unloading mechanism for receiving the electronic trays and placing them on different string guide shafts;

[0009] The unloading mechanism comprises a unloading receiving tray and a first transverse guide rail, and the unloading receiving tray is arranged below the grabbing mechanism and can slide horizontally along the first transverse guide rail;

[0010] The unloading receiving tray comprises a base plate, a supporting plate and a limiting adjustment plate. The supporting plate has two or more, and the supporting plates are slidably arranged on the base plate. The supporting plates can be moved closer to each other to support the electronic trays, and can be slid outward to make the electronic trays fall;

[0011] The limiting adjustment plate is coaxially disposed on the upper surface of the support plate. The limiting adjustment plate has a limiting part opposite to the edge of the electronic material tray. The distance of the limiting adjustment plate is adjustable to accommodate electronic material trays of different sizes.

[0012] Furthermore, the limiting adjustment plate has two parts, and the limiting part is provided on the opposite side of the limiting adjustment plate. The limiting part has an arc-shaped structure.

[0013] Furthermore, the receiving mechanism includes a first drive motor, a second drive motor, and two support plate push-pull cylinders;

[0014] The first drive motor is used to drive the unloading tray to slide horizontally along the first transverse guide rail, the second drive motor is used to adjust the distance of the limit adjustment plate, and the support plate push-pull cylinder is used to drive the support plates to move closer and further apart.

[0015] Furthermore, the support plate and the base plate are slidably connected by a support plate slider;

[0016] The limiting adjustment plate and the supporting plate are slidably connected by an adjustment plate slider.

[0017] Furthermore, the receiving mechanism also includes two or more buffer supports, which are disposed on the side of the material string guide shaft and are used to buffer the electronic material tray falling onto the material string guide shaft.

[0018] Furthermore, the buffer support can swing downward elastically, allowing the electronic material tray to fall onto the base plate at the bottom of the material string guide shaft under the action of gravity.

[0019] Furthermore, a servo module is connected to the material string guide shaft and the buffer support. When the servo module detects that the material string guide shaft is connected to an electronic material tray, it drives the material string guide shaft to descend by the height of one electronic material tray.

[0020] Furthermore, the servo module includes a servo motor and a vertical guide rail. The material string guide shaft is slidably mounted on the vertical guide rail via a slider and is driven by the servo motor to move up and down along the vertical guide rail.

[0021] To solve the above-mentioned technical problems, the present invention also provides another technical solution:

[0022] An automatic feeding method for electronic trays, applicable to the automatic feeding device for electronic trays described in any of the above technical solutions, includes the following steps:

[0023] The electronic material tray is gripped by the material gripping mechanism;

[0024] Adjust the width of the limit adjustment plate to make it compatible with the electronic material tray;

[0025] Drive the unloading tray to the bottom of the gripping mechanism to receive the electronic tray;

[0026] Drive the unloading tray to the top of the material string guide shaft, and drive the support plate to separate so that the electronic material tray falls onto the material string guide shaft.

[0027] Furthermore, it also includes the following steps:

[0028] Each time the material string guide shaft is detected to be connected to an electronic material tray, the material string guide shaft is driven to descend by the height of one electronic material tray.

[0029] When the electronic material tray on the material string guide shaft reaches the preset value, the material string guide shaft is pushed to the discharge position along the second transverse guide rail by the discharge cylinder.

[0030] Unlike existing technologies, the above-mentioned automatic electronic material tray unloading device includes a gripping mechanism, a receiving mechanism, and a unloading mechanism. The unloading receiving tray includes a base plate, a support plate, and a limiting adjustment plate. There are two or more support plates, which are slidably mounted on the base plate. The support plates can approach each other to support the electronic material tray and can slide outwards to allow the electronic material tray to fall. The limiting adjustment plate is coaxially mounted on the upper surface of the support plate and has a limiting portion opposite to the edge of the electronic material tray. The distance between the limiting adjustment plates is adjustable to accommodate electronic material trays of different sizes. Therefore, the spacing of the limiting adjustment plates can be adjusted according to the size of the electronic material tray, ensuring that electronic material trays of different sizes can accurately fall onto the support plate and be placed on different material string guide shafts via the unloading receiving tray, thereby achieving unloading of electronic material trays of different sizes. This automatic electronic tray unloading device is applicable to electronic trays of different sizes, and there is no need to change the fixture during the unloading process, which greatly reduces the equipment investment cost and improves the unloading efficiency of electronic trays.

[0054] Please see Figures 1 to 7 This embodiment provides an automatic feeding device and method for electronic material trays. This embodiment can feed electronic material trays 100 of different sizes, reduce the equipment investment cost of electronic material trays 100, and improve the feeding efficiency of electronic material trays.

[0055] like Figure 1 The diagram shown is a structural schematic of the automatic electronic tray feeding device described in this embodiment. The automatic electronic tray feeding device includes: a gripping mechanism 1, a feeding mechanism 2, and a receiving mechanism 3. The gripping mechanism 1 is positioned above the feeding mechanism 2, and the feeding mechanism 2 is positioned above the receiving mechanism 3. The receiving mechanism 3 includes two or more parallel material string guide shafts 31. The gripping mechanism 1 grips the electronic tray 100 and places it on the feeding mechanism 2. The feeding mechanism 2 is used to receive the electronic tray 100 and place it on different material string guide shafts 31, as well as to move the electronic tray 100 above different material string guide shafts 31, and to place the electronic tray on different material string guide shafts 31 according to regulations.

[0056] The material gripping mechanism 1 is used to grip the electronic material tray 100. The material gripping mechanism 1 includes a material tray gripper 11. A circular hole is provided in the middle of the electronic material tray 100, and the material tray gripper 11 can grip the electronic material tray through the circular hole.

[0057] The feeding mechanism 2 includes a feeding receiving tray 21, a first drive motor 23, and a first transverse guide rail 22. The feeding receiving tray 21 is located below the gripping mechanism 1 and can slide horizontally along the first transverse guide rail 22. Figure 3 As shown, the unloading tray 21 is slidably mounted on the first transverse guide rail 22 via a slider, and the unloading tray 21 is connected to the first drive motor 23 via a first belt 231. The first drive motor 23 drives the unloading tray 21 to slide on the first transverse guide rail 22 via the first belt 231.

[0058] like Figure 4 , Figure 5 and Figure 6 As shown, the unloading tray 21 includes a base plate 210, a support plate 212, and a limiting adjustment plate 211. There are two or more support plates 212, which are slidably disposed on the base plate 210. The support plates 212 can approach each other to support the electronic material tray 100, and can slide outwards to allow the electronic material tray to fall. The limiting adjustment plate 211 is coaxially disposed on the upper surface of the support plate 212. The limiting adjustment plate 211 has a limiting portion opposite to the edge of the electronic material tray. The distance between the limiting adjustment plates 211 is adjustable to accommodate electronic material trays of different sizes.

[0059] The substrate 210, the support plate 212, and the limiting adjustment plate 211 may be made of metals such as steel, aluminum, or aluminum alloy. The substrate 210 has a through hole in the middle for the electronic material tray to pass through, and the support plate 212 and the limiting adjustment plate 211 are disposed at the through hole.

[0060] like Figure 5 As shown, the receiving mechanism 3 also includes a second drive motor 213, a second belt 230, and two support plate push-pull cylinders 214. The second drive motor 213 is used to adjust the distance of the limit adjustment plate 211 so that the unloading receiving tray 21 can be adapted to electronic trays of different sizes. The support plate push-pull cylinders 214 are used to drive the support plates 212 to move closer and further apart. When the unloading receiving tray 21 needs to receive the electronic tray lowered by the grabbing mechanism, the support plate push-pull cylinders 214 drive the support plates 212 to move closer to each other, so that the electronic tray will not fall from the channel in the middle of the support plate 212. The distance of the limit adjustment plate 211 is adjusted by the second drive motor 213 so that the space between the multiple limit parts is slightly larger than the size of the electronic tray to be received. After receiving the electronic material tray lowered by the material grabbing mechanism, the unloading tray 21 slides along the first transverse guide rail 22 to the top of the corresponding material string guide shaft. Then, the support plate push-pull cylinder 214 drives the support plate 212 to separate from each other, so that the electronic material tray falls onto the material string guide shaft.

[0061] In this embodiment, the spacing of the limiting adjustment plates can be adjusted according to the size of the electronic material tray, so that electronic material trays of different sizes can be accurately placed on the support plate and placed on different material string guide shafts through the unloading tray, thereby realizing the unloading of electronic material trays of different sizes. This automatic electronic material tray unloading device is applicable to electronic material trays of different sizes, and there is no need to change the fixture during the unloading process, which greatly reduces the equipment investment cost and improves the unloading efficiency of electronic material trays.

[0062] like Figure 4 As shown, in one embodiment, there are two limiting adjustment plates 211, and limiting portions are respectively provided on opposite sides of the limiting adjustment plates 211. The limiting portions are arc-shaped structures. In this embodiment, the arc-shaped limiting portions can better fit with the circular electronic material tray, thereby better limiting the position of the electronic material tray on the support plate and preventing the electronic material tray from shifting when the unloading tray slides at high speed.

[0063] like Figure 5 and Figure 6 As shown, in one embodiment, the support plate 212 and the base plate 210 are slidably connected by a support plate slider 2120; the limit adjustment plate 211 and the support plate 212 are slidably connected by an adjustment plate slider 2110.

[0064] In this embodiment, the support plate push-pull cylinders are respectively disposed on the corresponding limit adjustment plates. When the distance between the limit adjustment plates 211 is adjusted by the second drive motor 213, the support plate 212 will also move synchronously with the limit adjustment plates 211. When the support plate is pushed or pulled to both sides, the limit adjustment plates 211 will remain stationary relative to the substrate 210. Therefore, when the support plate separates from the electronic material tray and falls, the limit adjustment plates 211 can still accurately limit the position, so that the electronic material tray can accurately fall onto the material string guide shaft 31.

[0065] like Figure 2 As shown, in one embodiment, the receiving mechanism 3 further includes two or more buffer supports 35. The buffer supports 35 are disposed beside the material string guide shaft 31 and are used to buffer the electronic material tray falling onto the material string guide shaft 31. Each material string guide shaft has one buffer support 35, which extends from the side of the material string guide shaft towards the center. When the electronic material tray falls, it first contacts the buffer support and then falls to the bottom of the material string guide shaft. A spring is hinged to the side of the buffer support away from the material string guide shaft, providing an upward elastic force. The buffer support 35 can elastically swing downwards, allowing the electronic material tray to fall onto the base plate 32 at the bottom of the material string guide shaft 31 under the action of gravity. This allows the buffer support to absorb the impact force of the falling electronic material tray, ensuring the electronic material tray lands smoothly at the bottom of the material string guide shaft.

[0066] like Figure 2 As shown, in one embodiment, a servo module 34 is connected to the material string guide shaft 31 and the buffer support 35. The servo module 34 drives the material string guide shaft 31 to descend by the height of one electronic material tray whenever it detects that the material string guide shaft 31 has been connected to an electronic material tray. The servo module 34 includes a servo motor and a vertical guide rail. The material string guide shaft and the buffer support are slidably mounted on the vertical guide rail via a slider and are driven to move up and down along the vertical guide rail by the servo motor. When the material string guide shaft 31 is detected to have been connected to an electronic material tray, it is driven to descend by the height of one electronic material tray.

[0067] like Figure 2 As shown, in this embodiment, the receiving mechanism 3 further includes a second transverse guide rail 33 and a discharge cylinder 36; the material string guide shaft 31 is slidably disposed on the second transverse guide rail 33, and the discharge cylinder 36 is used to push the material string guide shaft 31 along the second transverse guide rail 33 to the discharge position, thereby facilitating the removal of the electronic material tray on the material string guide shaft.

[0068] like Figure 7 As shown, the present invention also provides another embodiment of an automatic electronic tray feeding method. This automatic electronic tray feeding method is applicable to the automatic electronic tray feeding device described in any of the above embodiments, and includes the following steps:

[0069] S101. The electronic material tray is grasped by the material gripping mechanism;

[0070] S102. Adjust the width of the limiting adjustment plate to make the limiting adjustment plate fit the electronic material tray;

[0071] S103. Drive the unloading tray to the bottom of the gripping mechanism to receive the electronic tray;

[0072] S104. Drive the unloading tray to the top of the material string guide shaft, and drive the support plate to separate so that the electronic material tray falls onto the material string guide shaft.

[0073] When the unloading tray 21 needs to receive the electronic material tray lowered by the gripping mechanism, the support plate push-pull cylinder 214 drives the support plates 212 to move closer together, so that the electronic material tray will not fall from the channel in the middle of the support plate 212. The distance between the limit adjustment plates 211 is adjusted by the second drive motor 213, so that the space between the multiple limit parts is slightly larger than the size of the electronic material tray to be received. After the unloading tray 21 receives the electronic material tray lowered by the gripping mechanism, it slides along the first transverse guide rail 22 to above the corresponding material string guide shaft. Then, the support plate push-pull cylinder 214 drives the support plates 212 to separate, allowing the electronic material tray to fall onto the material string guide shaft.

[0074] In this embodiment, the spacing of the limiting adjustment plates can be adjusted according to the size of the electronic material tray, so that electronic material trays of different sizes can be accurately placed on the support plate and placed on different material string guide shafts through the unloading tray, thereby realizing the unloading of electronic material trays of different sizes. This automatic electronic material tray unloading device is applicable to electronic material trays of different sizes, and there is no need to change the fixture during the unloading process, which greatly reduces the equipment investment cost and improves the unloading efficiency of electronic material trays.

[0075] Furthermore, in one embodiment, the automatic feeding method for the electronic tray further includes the step of:

[0076] Each time the material string guide shaft 31 is detected to be connected to an electronic material tray, the material string guide shaft 31 is driven to descend by the height of one electronic material tray.

[0077] When the electronic material tray on the material string guide shaft 31 reaches the preset value, the material string guide shaft 31 is pushed to the discharge position along the second transverse guide rail 33 by the discharge cylinder 36.

[0078] In this embodiment, a spring is hinged and connected to the side of the buffer support away from the material string guide shaft. The spring provides an upward elastic force to the buffer support, which can elastically swing downward, allowing the electronic material tray to fall onto the base plate 32 at the bottom of the material string guide shaft 31 under the action of gravity. This allows the buffer support to absorb the impact force when the electronic material tray falls, ensuring that the electronic material tray lands smoothly at the bottom of the material string guide shaft.

[0079] The automatic electronic material tray unloading device in the above embodiment includes a gripping mechanism 1, a receiving mechanism 3, and a unloading mechanism 2. The unloading receiving tray includes a base plate 210, a support plate, and a limiting adjustment plate. There are two or more support plates, which are slidably disposed on the base plate 210. The support plates can approach each other to support the electronic material tray and can slide outwards to allow the electronic material tray to fall. The limiting adjustment plate is coaxially disposed on the upper surface of the support plate and has a limiting portion opposite to the edge of the electronic material tray. The distance between the limiting adjustment plates is adjustable to accommodate electronic material trays of different sizes. Therefore, the spacing of the limiting adjustment plates can be adjusted according to the size of the electronic material tray, so that electronic material trays of different sizes can accurately fall onto the support plate and be placed on different material string guide shafts 31 via the unloading receiving tray, thereby realizing the unloading of electronic material trays of different sizes. This automatic electronic tray unloading device is applicable to electronic trays of different sizes, and there is no need to change the fixture during the unloading process, which greatly reduces the equipment investment cost and improves the unloading efficiency of electronic trays.

[0080] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
