DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-5 , the present invention provides a technical solution: a positioning device for chip testing, comprising a positioning body 1, which is used for placing and positioning the chip; The conveying body 2 is arranged at the bottom of the positioning body 1, and its central axis corresponds to the central axis of the positioning body 1 in the vertical direction; Also includes; A testing mechanism 3 is provided at one side of the top of the positioning body 1 and is used to test the chip positioned on the positioning body 1; The lower ejection mechanism 4 is arranged at the other side of the top of the positioning body 1, and is used to eject the chip after the test downward to the top of the conveying body 2 to complete the output work; An upper ejection mechanism 7 is also provided above the conveying body 2, which is used to eject the chip conveyed on the conveying body 2 upward to the positioning body 1; The present application provides a positioning device for chip testing with a lower ejection mechanism 4 and an upper ejection mechanism 7. Specifically, when in use, first, the chip to be tested is placed above the conveying body 2, and then the chip is allowed to reach the position of the upper ejection mechanism 7 along with the conveying body 2. Then, the upper ejection mechanism 7 is started to drive the chip to move upward to the top of the positioning body 1 for positioning. Then, the testing mechanism 3 can be started to complete the testing of the positioned chip. After the test is completed, the positioning body 1 drives the chip after the test to be transferred to the position of the lower ejection mechanism 4, and then the lower ejection mechanism 4 is started, so that the positioned chip can be dropped again above the conveying body 2 and conveyed by the conveying body 2, thereby completing the automatic loading and positioning, detection and unloading and conveying effects of the chip.

[0019] Among them, according to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a circular rotating worktable 11 is arranged in the middle of the positioning body 1, a cylinder is coaxially connected to the bottom of the rotating worktable 11, and a driving assembly 8 is arranged outside the cylinder for rotating the cylinder; The driving assembly 8 includes a driving motor 81, a driving gear 82 and a meshing gear 83. The top of the driving motor 81 is coaxially connected to the driving gear 82, and the top of the driving gear 82 is connected to the bottom bearing of the positioning body 1. The outer side of the driving gear 82 is meshed with the meshing gear 83, and the meshing gear 83 is coaxially connected to the bottom of the cylinder. Two placement grooves 12 are symmetrically arranged outside the rotating worktable 11, and a through groove 10 is symmetrically arranged below the placement groove 12. The through groove 10 penetrates the positioning body 1, and an extrusion limiting mechanism is arranged inside the placement groove 12 for performing extrusion limiting work of the chip; Among them, when the chip is lifted up by the lower ejection mechanism 4, the chip will be moved upward to the top of the corresponding placement groove 12 for positioning to complete the test work. After that, it is necessary to start the drive motor 81 to drive the active gear 82 at its top to rotate. When the active gear 82 rotates, it will mesh with the meshing gear 83, so that the meshing gear 83 drives the cylinder coaxially connected with it to rotate. The rotation of the cylinder drives the rotating workbench 11 to rotate, which can achieve the effect of changing the position of the two placement grooves 12. Therefore, the chip after the test is completed reaches the bottom of the lower ejection mechanism 4, is ejected by the lower ejection mechanism 4, and reaches the top of the conveying body 2 to complete the output work.

[0020] Further, according to Figure 6 and Figure 7 As shown, the conveying body 2 includes two fixed frames 21, a rotating roller 22 and a conveyor belt 23. The rotating rollers 22 are arranged at the middle bearings of the two fixed frames 21, and the conveyor belts 23 are wound around the outsides of the rotating rollers 22 at the front and rear ends. A control motor is coaxially connected to the top end of one rotating roller 22 for controlling the rotating roller 22 to rotate.

[0021] The outside of the conveyor belt 23 is evenly distributed with reserved grooves 24, and the reserved grooves 24 penetrate the conveyor belt 23. An intermediate plate is fixed in the middle of the conveyor belt 23, and both sides of the intermediate plate are connected to the fixing frame 21. An upper ejection mechanism 7 is arranged above the intermediate plate, and the position of the upper ejection mechanism 7 corresponds to the position of the testing mechanism 3. A limiting plate 241 is arranged around the inside of the reserved slot 24 for placing the chip; In the present application, first, the chips to be tested are placed on the limit plates 241 inside the reserved slots 24 according to the positions of the reserved slots 24 on the conveyor belt 23. Then, the control motor is started to drive the rotating roller 22 to rotate. When the rotating roller 22 rotates, it drives the conveyor belt 23 to transport the chips in the reserved slots 24 on the conveyor belt 23.

[0022] Furthermore, according to Figure 1 As shown, the test mechanism 3 includes a first fixed frame 31, a first cylinder 32 and a test body 33. The first fixed frame 31 is arranged in an "L" shape, and the first cylinder 32 and the test body 33 are connected at the bottom of the top thereof; After the chip reaches the placement slot 12 and is positioned, the first cylinder 32 at the bottom of the first fixed frame 31 can be started to drive the test body 33 at the bottom thereof to descend, thereby completing the test of the chip.

[0023] In this application, according to Figure 1 and Figure 2 As shown, the lower ejection mechanism 4 includes a second fixed frame 41, a second cylinder 42 and a lower ejector head 43. The shape of the second fixed frame 41 is the same as that of the first fixed frame 31, and the second cylinder 42 and the lower ejector head 43 are connected to each other at the top and bottom of the second fixed frame 41. The positions of the testing mechanism 3 and the lower ejection mechanism 4 correspond to the positions of the placement slots 12, and the distance between the testing mechanism 3 and the lower ejection mechanism 4 is the same as the distance between adjacent reserved slots 24; Specifically, in the process of conveying the chips in the reserved slots 24 by the conveyor belt 23, since the positions of the reserved slots 24 correspond to the positions of the two placement slots 12, the chip loading work can be completed in the placement slots 12 at the bottom of the test mechanism 3, and the chip unloading work can be completed at the same time, thereby achieving the effect of continuous loading and unloading and improving the test efficiency; When unloading, it is necessary to start the second cylinder 42 at the bottom of the second fixed frame 41 to drive the lower ejector 43 at the bottom thereof to descend, thereby completing the effect of ejecting and conveying the chips in the placement slot 12 below it downward.

[0024] As a further preferred embodiment of this invention, according to Figure 3 As shown, the extrusion limiting mechanism includes a placement component 5 and an extrusion component 6, which are arranged at staggered positions on four sides of the placement slot 12, and the placement component 5 is arranged at a position biased toward the lower side of the placement slot 12, and the extrusion component 6 is arranged at an upper side of the placement slot 12, and the placement component 5 and the extrusion component 6 are both composed of two rotating baffle mechanisms 9; When the chip is fed from bottom to top into the extrusion limiting mechanism, the chip is lifted up by the upper ejection mechanism 7 at the bottom, and the extrusion placement component 5 and the extrusion component 6 rotate upward together. When the chip is lifted up, when the chip is completely separated from the placement component 5 but not separated from the extrusion component 6, the upper ejection mechanism 7 needs to be closed. At this time, the chip automatically falls, and the placement component 5 is reset to a horizontal state, so that the chip can fall to the placement component 5 for placement. At this time, the extrusion component 6 is reset and tilted downward, and the chip is squeezed, thereby completing the limiting work. When unloading, the chip will be squeezed by the lower ejection mechanism 4, causing it to drive the placement component 5 to descend. When the chip is completely separated from the placement component 5, the chip falls onto the limiting plate 241 on the corresponding reserved groove 24 for limiting, and is then completely transported out by the conveyor belt 23.

[0025] Specifically, according to Figure 7 As shown, the upper ejection mechanism 7 includes a third cylinder 71 and a top plate 72. The top plate 72 is provided at the top of the third cylinder 71, and the central axis of the top plate 72 coincides with the central axis of the testing mechanism 3. When lifting upward, the third cylinder 71 needs to be started so that it drives the top plate 72 to move upward, thereby achieving the effect of lifting upward.

[0026] As a further preferred embodiment of this invention, according to Figure 8 and Fig. 9As shown, the rotating baffle mechanism 9 includes a fixing rod 91, a baffle assembly 92 and a torsion spring 93. The fixing rod 91 is fixedly arranged in a groove on the inner wall of the placement slot 12, and its outer portion is connected to the baffle assembly 92 through the torsion spring 93. The baffle assembly 92 is an up-and-down rotating mechanism under the action of the torsion spring 93. The baffle assembly 92 on the placement assembly 5 is initially in a horizontal state, and the baffle assembly 92 on the extrusion assembly 6 is initially in a downwardly inclined state. When the placement component 5 and the extrusion component 6 rotate, the baffle component 92 rotates. When the baffle component 92 rotates, it causes the torsion spring 93 to deform. Therefore, when the placement component 5 and the extrusion component 6 are not subjected to the extrusion force of the ejection mechanism, they will be reset under the action of the torsion spring 93 and return to the initial state, completing the extrusion and placement of the chip. The baffle assembly 92 includes a rotating seat 921, a middle hole 922, a mounting groove 923, a rotating plate 924 and a mounting block 925. The outer side of the rotating seat 921 is penetrated by a middle hole 922 for connecting with the fixing rod 91 through a torsion spring 93, and a mounting groove 923 is provided at the top of the rotating seat 921. The inside of the mounting groove 923 is connected to the mounting block 925, and the rotating plate 924 with an inclined bottom structure is integrally installed at the top of the mounting block 925. There is a disassembly and installation structure between the rotating seat 921 and the installation block 925, and its installation method is any one of bolts, screws or mortise and tenon joints; When it is necessary to test chips of different sizes, the mounting block 925 and the mounting slot 923 can be disassembled according to the gears of the chip. After that, the rotating plates 924 of different sizes can be replaced, thereby completing the positioning of chips of different sizes, ensuring that the entire device has a wider range of applications. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
