Description

Technical Field

[0001] The present invention relates to the technical field of chip production, and in particular to an automatic chip tray closing device and a tray closing method. Background Art

[0002] Nowadays, electronic products are becoming more and more abundant. As the core of electronic products, the quality of chips directly affects the performance of the terminal. Therefore, many semiconductor manufacturers will do some testing on the packaged chips, and the chips need to circulate inside the testing machine. There are many types of chips, and the size of the single chip is small, which is not suitable for single transportation. The chips are often transported by trays. According to the needs of chip transportation, a full tray is often stacked with an empty tray on top to prevent the chip from running out of the tray slot or even slipping during transportation. The existing tray closing method often manually places an empty tray on a full tray, which affects production efficiency. The automatic tray closing mechanism has a poor coupling effect. The closing tray will instantly vibrate the chip inside, shaking the chip out of the slot, and there is no detection of the closing tray state, which affects the subsequent related functions of the machine. Summary of the invention

[0003] Technical purpose: In view of the shortcomings of the existing chip tray assembling method in the production process, the present invention discloses an automatic chip tray assembling device and a method for assembling chip trays, which can ensure the assembling effect and detect the assembling situation.

[0004] Technical solution: To achieve the above technical objectives, the present invention adopts the following technical solution:

[0005] A chip tray automatic closing device comprises a fixed plate group, on which are arranged a guide mechanism for guiding and adjusting a placed empty tray and a support mechanism for supporting the tray; a lifting and closing mechanism for driving a full tray loaded with chips to move up and close it with a placed empty tray is arranged below the fixed plate group; the support mechanism supports the placed empty tray and the closed tray as a whole, and a positioning mechanism for arranging and positioning the closed tray is arranged on the side of the tray.

[0006] Preferably, the guiding mechanism of the present invention comprises long side guide blocks and short side guide blocks which are arranged around the tray placement area, and which interact with the edges of the empty tray to guide and locate the position where the empty tray is placed during the placement of the empty tray; the short side guide blocks and the long side guide blocks are both provided with guiding slopes arranged along the direction of placement of the empty tray on one side close to the edge of the tray.

[0007] Preferably, the long side guide block of the present invention is rotatably set on the fixed plate group, and the upper part of the long side guide block adopts a conical structure eccentrically set to the rotation center, and the side of the conical structure is used to form a guide slope, and the distance between the guide slopes in relative positions is changed by rotating the long side guide block.

[0008] Preferably, the support mechanism of the present invention adopts a telescopic block arranged in a direction perpendicular to the edge of the material tray, and the telescopic block is driven by a cylinder to move forward and backward in a direction toward the edge of the material tray to switch the support state.

[0009] Preferably, the positioning mechanism of the present invention includes a positioning cylinder arranged diagonally along the corner of the material tray and a positioning clamp fixed at the driving end of the positioning cylinder. The positioning clamp is provided with a V-shaped groove matching the edge of the material tray. The positioning clamp is driven by the positioning cylinder to move so that the V-shaped groove fits with the edge of the material tray to position the material tray.

[0010] Preferably, the fixed plate group of the present invention includes two fixed plates arranged at the same plane height, and a space for the tray to pass through is formed between the fixed plates. The tray lifting and closing mechanism includes an electric cylinder and a support plate fixed on the upper end of the electric cylinder. The electric cylinder pushes the full tray upward through the support plate to close it with the placed empty tray.

[0011] Preferably, the empty tray of the present invention is placed by clamping with a clamping claw, and the clamping claw includes clamping plates symmetrically arranged on both sides of the empty tray, and a clamping groove cooperating with the edge of the empty tray is arranged at the bottom of the clamping plate. During the process of placing the empty tray, the empty tray can be moved in the clamping groove to adjust its position under the action of the guide mechanism.

[0012] Preferably, a detection sensor for detecting the closing state of the trays is provided on the fixed plate assembly of the present invention.

[0013] The present invention discloses an automatic tray closing method for chip trays. By using the tray closing device, a full tray loaded with chips is conveyed to above a tray lifting and closing mechanism, and an empty tray is placed on a fixed plate group. During the placing process, the position of the empty tray is adjusted by a guide mechanism to correspond to the full tray in the height direction. After the placing is completed, the empty tray is supported by a support mechanism. Then, the tray lifting and closing mechanism drives the full tray to rise, and after the full tray contacts the empty tray, the empty tray is driven to move up synchronously, and the support mechanism cancels the support for the empty tray. When the full tray rises to a height higher than the support mechanism, the tray lifting and closing mechanism moves down, and the support mechanism supports the tray after the closing through the edge of the full tray. The positioning mechanism on the fixed plate group positions the edges of the full tray and the empty tray, so that the full tray and the empty tray are accurately closed, and the chips are confined in the slots of the full tray.

[0014] Preferably, when the present invention adjusts the position of the empty tray through the guide mechanism, the position of the empty tray is adjusted by the guide slope on the guide mechanism, and during the downward movement of the empty tray, the long side guide block and the short side guide block of the guide mechanism respectively exert force on the long side and short side of the empty tray, so that after the empty tray is adjusted by the guide mechanism, the position of the tray falling on the fixed component remains uniform; when the specifications of the tray change, the long side guide block is rotated to adjust the spacing accordingly.

[0015] Beneficial effects: The chip tray automatic closing device and closing method provided by the present invention have the following beneficial effects:

[0016] 1. The present invention sets a guide mechanism on the fixed plate group to adjust the position of the empty tray during the placement process, thereby ensuring the corresponding position of the empty tray and the full tray of the tray, and positioning the tray state through the positioning mechanism after the tray is closed to ensure the accuracy of docking, which is beneficial to the subsequent chip transportation and detection.

[0017] 2. The guiding mechanism of the present invention can gradually guide the empty material tray by setting a guiding slope along the height direction so that its position meets the requirements, and the long side guide block can adjust the distance between the two relatively set long side guide blocks by rotation to meet the guiding requirements of material trays of different specifications, while saving the occupied space of the structure and facilitating the arrangement of components on the fixed plate group.

[0018] 3. The positioning mechanism of the present invention fits the edge of the tray after the tray is assembled through the V-shaped groove, so as to sort the tray after the tray is assembled, further ensure the accuracy of the tray assembly, ensure the coupling effect of the tray, and reliably limit the placed chips.

[0019] 4. The empty material tray of the present invention is clamped and placed by a clamping plate. During the placement process, the position of the empty material tray can be automatically adjusted in the clamping groove under the action of the guide mechanism, which simplifies the adjustment and positioning process of the empty material tray and improves the efficiency of closing the tray.

Each embodiment and example is provided by explaining the apparatus, composition and materials of the present disclosure, rather than limiting. On the contrary, the following description provides a convenient illustration of an exemplary embodiment for implementing the present disclosure. In fact, it will be clear to those skilled in the art that various modifications and variations can be made in the teachings of the present disclosure without departing from the scope or spirit of the present disclosure. For example, a feature shown or described as a part of an embodiment can be used in conjunction with another embodiment to produce yet another embodiment. It is expected that the present disclosure covers such modifications and variations within the scope of the appended claims and their equivalents. Other objects, features and aspects of the present disclosure are disclosed in or clear from the following detailed description. It will be understood by those of ordinary skill in the art that this discussion is only a description of exemplary embodiments and is not intended to limit the wider aspects of the present disclosure.

[0027] like Figure 1-Figure 4 As shown, the present invention discloses an automatic chip tray closing device, comprising a fixed plate group 1, on which a guide mechanism for guiding and adjusting a placed empty tray and a support mechanism 2 for supporting the tray are arranged, a lifting and closing mechanism 3 for driving a full tray loaded with chips to move up and close it with a placed empty tray is arranged below the fixed plate group 1; the support mechanism 2 supports the placed empty tray and the tray after closing as a whole, and a positioning mechanism 4 for arranging and positioning the tray after closing is arranged on the side of the tray.

[0028] Specifically, the guiding mechanism of the present invention includes a long side guiding block 5 and a short side guiding block 6 which are arranged around the tray placement area. During the placement of the empty tray, the guiding blocks 5 interact with the edge of the empty tray to guide and locate the position of the empty tray. Both the short side guiding block 6 and the long side guiding block 5 are provided with a guiding slope arranged along the placement direction of the empty tray on one side close to the edge of the tray. The guiding slope can be used to synchronously perform guiding adjustments during the placement of the empty tray. On the one hand, the stability of the guiding adjustment process can be ensured, while saving process time and improving the efficiency of the tray closing operation. In a specific embodiment, the empty tray is placed by clamping with a clamp, and the clamp includes a clamping plate 13 symmetrically arranged on both sides of the empty tray, and a clamping groove 14 cooperating with the edge of the empty tray is arranged at the bottom of the clamping plate 13. During the placement of the empty tray, the empty tray can be moved in the clamping groove 14 to adjust its position under the action of the guiding mechanism.

[0029] like Figure 4As shown, the long side guide block 5 of the present invention is rotatably set on the fixed plate group, and the upper part of the long side guide block 5 adopts a conical structure eccentrically set to the rotation center, and the side of the conical structure is used to form a guiding slope. The spacing between the guiding slopes in relative positions is changed by rotating the long side guide block 5. Compared with the adjustment method using a translational method, the adjustment structure of the present invention can save the space occupied by components, which is beneficial to the arrangement of various components on the surface of the fixed plate group; at the same time, the long side guide block 5 of the present invention can be connected to a motor to rotate, and it can be rotated synchronously during the guiding process, so that the spacing between the guiding slopes changes from large to small, so that the structure can be compatible with a larger placement deviation of the material tray, and reduce the positioning accuracy requirements of the equipment; the corresponding short side guide block 6 can adopt the same structure as the long side guide block 5, or it can use the existing wedge block structure with an inclined plane to achieve the guiding effect.

[0030] The fixed plate group 1 of the present invention includes two fixed plates 10 arranged at the same plane height, and a space for the tray to pass through is formed between the fixed plates 10. The tray lifting and closing mechanism 3 includes an electric cylinder 11 and a support plate 12 fixed on the upper end of the electric cylinder 11. The electric cylinder 11 pushes the full tray up through the support plate 12 to close the empty tray placed thereon; the support mechanism 2 adopts a telescopic block arranged in a direction perpendicular to the edge of the tray. The telescopic block is driven by the cylinder to move forward and backward in the direction toward the edge of the tray to switch the support state, and the cylinder is kept fixed by the fixed plate 10; the positioning mechanism 4 includes a positioning air cylinder arranged in a diagonal direction along the corner of the tray. The cylinder 7 and the positioning clamping block 8 fixed on the driving end of the positioning cylinder 7, the positioning clamping block 8 is provided with a V-shaped groove 9 matching the edge of the material tray, and the positioning clamping block 8 is driven by the positioning cylinder 7 to move so that the V-shaped groove 9 fits with the edge of the material tray to position the material tray. In this way, even if there is a certain deviation of the material tray when the trays are closed, it can be adjusted with the positioning mechanism to ensure the coupling state of the two material trays after closing, and to ensure the stability of the position of the chip in the slot of the material tray. The positioning mechanism 4 can be set at the four corners of the material tray if space permits. When the installation space is limited, it can be set along the diagonal of the material tray to ensure the positioning effect.

[0031] In addition to mechanical positioning to ensure the closing effect, a detection sensor 15 for detecting the closing state of the tray is provided on the fixed plate group 1 of the present invention. The detection sensor 15 is also fixed on the fixed plate 10, with the detection end facing the direction of the tray. Through different installation heights, empty tray detection and warping detection on the upper surface of the empty tray can be realized.

[0032] The present invention also discloses an automatic tray closing method for chip trays. By using the above-mentioned tray closing device, a full tray loaded with chips is conveyed to the top of a tray lifting and closing mechanism 3, and an empty tray is placed on a fixed plate group 1. During the placement process, the position of the empty tray is adjusted by a guide mechanism to correspond to the full tray in the height direction. After the placement is completed, the empty tray is supported by a support mechanism 2; then the tray closing mechanism 3 is lifted up to drive the full tray to rise. After the full tray contacts the empty tray, the empty tray is driven to move up synchronously, and the support mechanism 3 cancels the support for the empty tray. When the full tray rises to a height higher than the support mechanism 3, the tray lifting and closing mechanism 3 is moved downward, and the support mechanism 3 supports the tray after closing through the edge of the full tray; the positioning mechanism on the fixed plate group positions the edges of the full tray and the empty tray, so that the full tray and the empty tray are accurately closed and the chips are confined in the slots of the full tray. The detection sensor 15 can detect the closing state and the warping degree of the surface of the empty tray.

[0033] When the present invention adjusts the position of the empty material tray through the guide mechanism, the position of the empty material tray is adjusted by the guide inclined surface on the guide mechanism. During the downward movement of the empty material tray, the long side guide block 5 and the short side guide block 6 of the guide mechanism respectively exert forces on the long side and the short side of the empty material tray, so that the position of the empty material tray falling on the fixed component remains uniform after being adjusted by the guide mechanism; when the specifications of the material tray change, the long side guide block 5 is rotated to adjust the spacing accordingly. When the accuracy of the material tray clamping and positioning is poor, it is possible that the edge of the material tray will exceed the guiding range of the currently rotating long side guide block 5. For this reason, the long side guide block 5 can be driven by a motor to rotate. During the placement of the material tray, the spacing of the guide inclined surfaces formed by the long side guide block 5 changes from the maximum range, so that the structure can be compatible with a larger range of deviations, thereby reducing the failure rate of tray closure and ensuring the efficiency of tray closure operations.
