[0002] In the production and use of chip, the performance of small batch chip sample is often required to be tested in detail to make decision for subsequent processing and production. When the small batch sample is tested, the chip is transferred from the chip storage tray to be tested to the test equipment for testing by the suction head of the suction mechanism. During the chip transfer process, the test personnel must be very careful. If the operation is improper, the suction is unstable or the vacuum mechanism fails, the chip will fall off the suction head of the suction mechanism, especially during the manual transfer process.

The chip may fall into the gap of the detection equipment or be damaged by vibration and falling. The falling of the chip may affect the test results. Since it is a small batch test, even if a few chips are damaged by falling, it will greatly affect the proportion of the test results. Therefore, the test personnel must be very careful, and the detection operation efficiency is low. During long-term experimental operation, the chip may inevitably fall off. SUMMARY

DETAILED DESCRIPTION

[0019] The utility model is further explained below in combination with the drawings and specific embodiments.

[0020] As Figure 1 And Figure 2The illustrated one kind chip test verification test manual transfer device includes hand handle 100 and adsorption mechanism 200, the inside vertical direction of the hand handle 100 is penetrated and the lower end is provided with the deformable protection head 130, the upper and lower ends of the adsorption mechanism 200 are provided with the communicating vacuum mechanism 240 and the adsorption head 230, the adsorption mechanism 200 is vertically elastically arranged in the hand handle 100, and the upper end of the adsorption mechanism 200 and the adsorption head 230 are located above the upper end and inside the lower end of the hand handle 100 respectively, the adsorption mechanism 200 is elastically lowered in the hand handle 100, and the protection head 130 is driven to deform and open the channel for the adsorption head 230 and the adsorbed chip to pass through, when the adsorption mechanism 200 is elastically raised to reset in the hand handle 100, the chip adsorbed by the adsorption head 230 is located inside the lower end of the hand handle 100, and the protection head 130 is reset with the chip adsorbed by the adsorption head 230.

[0021] In specific implementation, when the chip is picked up: the hand handle 100 is held, the thumb manually presses the driving adsorption mechanism 200 to move downward, the adsorption mechanism 200 drives the protection head 130 to deform and open the channel, before the adsorption head 230 passes through the protection head 130, the protection head 130 has opened the channel enough for the adsorption head 230 and the chip to pass through, during the process that the adsorption mechanism 200 is continuously driven to move downward, the lower end of the adsorption mechanism 200 moves to the lower side of the hand handle 100, the adsorption head 230 at the lower end of the adsorption mechanism 200 is aligned to move to pick up the chip to be adsorbed, the vacuum mechanism 240 is pressed before the adsorption head 230 contacts the chip, and the chip is adsorbed by the vacuum mechanism 240 after the adsorption head 230 contacts the chip.

[0022] When the chip is transferred and placed: the transfer device with the chip picked up and adsorbed is transferred to the position above the chip to be placed, the hand handle 100 is held, the thumb manually presses the driving adsorption mechanism 200 to move downward, the adsorption mechanism 200 drives the protection head 130 to deform and open the channel, before the adsorption head 230 and the chip pass through the protection head 130, the protection head 130 has opened the channel enough for the adsorption head 230 and the chip to pass through, during the process that the adsorption mechanism 200 is continuously driven to move downward, the lower end of the adsorption mechanism 200 moves to the lower side of the hand handle 100, the chip on the adsorption head 230 at the lower end of the adsorption mechanism 200 is aligned to the position to be placed, the vacuum mechanism 240 is pressed to eliminate the adsorption force of the chip below the chip, after the chip is placed, the adsorption mechanism 200 is elastically reset, and the protection head 130 is reset with the adsorption mechanism 200 during the process that the adsorption mechanism 200 continues to move upward and reset after the adsorption head 230 and the chip enter the lower end of the hand handle 100.

[0023] When the adsorption head 230 is adsorbing and picking up the chip, the lower end is located below the protective head 130, and there is a certain distance between the two. This distance can be determined according to the actual situation. When picking up and placing the chip in the concave acupoint, the protective head 130 does not cause obstruction.

[0024] During the transfer process, if the chip accidentally falls from the adsorption head 230, it is intercepted and limited by the protective head 130 to prevent it from falling completely out of the transfer device. This effectively improves the fault tolerance and safety of chip transfer during use and avoids the impact of accidental chip drops on test results.

[0025] Based on the above, such as Figures 1 to 3 As shown, the handle 100 includes an upper body 110 and a lower body 120 connected vertically. The lower inner wall of the upper body 110 is provided with a first elastic element limiting platform 111 with a horizontal inward protrusion. The adsorption mechanism 200 includes an upper driving rod 211, a transmission rod 212, a lower driving rod 221, and an adsorption rod 222 connected vertically in sequence. The transmission rod 212 is an integral structure with the upper driving rod 211, and its lower end is detachably connected to the upper end of the lower driving rod 221. The outer diameter of the upper driving rod 211 is larger than the inner diameter of the first elastic element limiting platform 111, and the outer diameter of the transmission rod 212 is smaller than the inner diameter of the first elastic element limiting platform 111. An elastic element 140 is provided between the upper end face of the first elastic element limiting platform 111 and the lower end face of the upper driving rod 211.

[0026] In this specific embodiment, the upper body 110 and the lower body 120 are connected by a threaded rotation. A downwardly protruding external threaded cylinder is provided at the middle part of the lower end of the first elastic element limiting platform 111. The inner diameter of the external threaded cylinder is smaller than the inner diameter of the first elastic element limiting platform 111, and the inner diameter of the external threaded cylinder is larger than the outer diameter of the lower drive rod 221. The outer diameter of the external threaded cylinder is smaller than the outer diameter of the upper body 110. An upwardly protruding internal threaded cylinder that matches and connects with the external threaded cylinder is provided at the upper end of the lower body 120. If the lower body (320) is damaged during long-term use, it can be directly replaced. The elastic element 140 is a spring sleeved on the transmission rod 212. In specific implementations, the elastic element 140 can also be set as other numbers or structures of elastic structures according to the actual situation. In practice, pressing down on the upper drive rod 211 will compress the elastic element 140. When the force applied to the upper drive rod 211 is gradually released, the upper drive rod 211 will move up and reset under the elastic force of the elastic element 140. The structure is simple and the operation is convenient.

[0027] Based on the above, such as Figure 2 and Figure 3As shown, the lower driving rod 221 and the adsorption rod 222 are integrated structure, the outer diameter of the lower driving rod 221 is greater than the inner diameter of the first elastic element limiting table 111. In the specific implementation, the elastic element 140 is in the compressed state after installation, and the outer diameter of the lower driving rod 221 is greater than the inner diameter of the first elastic element limiting table 111, which can limit the upper driving rod 211 and the transmission rod 212 connected with the lower driving rod 221, and avoid the adsorption mechanism 200 from being pulled out from the upper end of the hand-held handle 100. The structure is simple, convenient to use and less failure.

[0028] On the basis of the above, Figures 1 to 3 As shown, the upper end of the lower driving rod 221 is provided with a docking recess, the side wall of the docking recess is provided with a thread, the lower end of the transmission rod 212 is provided with a threaded section matched with the thread on the side wall of the docking recess, and the bottom of the docking recess is provided with an annular sealing gasket 213. In this specific embodiment, during installation, first, the elastic element 140 is arranged from the upper end of the upper main body 110 to the first elastic element limiting table 111, then the driving rod (211) and the transmission rod 212 are vertically arranged in the upper main body 110, the annular sealing gasket 213 is arranged on the docking recess at the upper end of the lower driving rod 221, the lower driving rod 221 is pressed downward to make the lower end of the transmission rod 212 protrude from the lower end of the upper main body 110, the upper end of the lower driving rod 221 with the docking recess and the annular sealing gasket 213 is rotationally connected with the lower end of the transmission rod 212, and finally the lower main body 120 is connected with the upper main body 110 to complete the assembly; the assembly structure is simple, and the annular sealing gasket 213 ensures the sealing performance of the adsorption mechanism 200 after installation.

[0029] On the basis of the above, Figures 1 to 5 As shown, the outer wall of the lower main body 120 is uniformly provided with a plurality of let-out holes 121 horizontally penetrating into the inside of the lower main body 120, the protective head 130 includes a plurality of elastic rods 131 same in number with the let-out holes 121, the upper ends of the plurality of elastic rods 131 are fixed one by one above the let-out holes 121 of the lower main body 120, the elastic rods 131 are provided with driving blocks 132 extending into the inside of the lower main body 120 through the let-out holes 121 at positions corresponding to the let-out holes 121, the lower ends of the plurality of elastic rods 131 are located below the lower main body 120 and are provided with anti-falling bosses 133 extending horizontally towards the axial direction of the lower main body 120, the lower driving rod 221 is columnar in shape and has an outer diameter greater than that of the adsorption rod 222, the vertical projection of the adsorption rod 222 is located inside the vertical projection of the plurality of driving blocks 132, and the lower end of the lower driving rod 221 is provided with a smooth driving arc surface 223 vertically corresponding to the driving blocks 132.

[0030] In this embodiment, the eight evenly arranged dislocation holes 121 and elastic rods 131 are provided. In actual implementation, the number of the dislocation holes 121 and the elastic rods 131 is six or eight. When the number is less, the structure of the elastic rod 131 is larger, and a larger force needs to be applied during operation, which is inconvenient for operation. When the number is too large, the structure is too complex, which is inconvenient for processing and increases the cost.

[0031] During operation, when the upper driving rod 211 is pressed to move downward, the driving arc surface 223 at the lower end of the lower driving rod 221 first contacts the driving protrusion 132, the driving protrusion 132 is driven to move outward elastically, the elastic rod 131 is deformed outward, the anti-falling boss 133 at the lower end of the elastic rod 131 moves outward to leave the corresponding position in the internal cavity at the lower end of the lower main body 120, and then the lower end of the suction rod 222 and the suction head 230 at the lower end of the suction rod 222 are moved downward to the lower main body 120 and the anti-falling boss 133, so as to take and place the chip.

[0032] When the pressure on the upper driving rod 211 is gradually reduced, the upper driving rod 211 is elastically moved upward to reset, the lower end of the suction rod 222 and the suction head 230 at the lower end of the suction rod 222 are moved upward to the lower end of the lower main body 120 and the anti-falling boss 133, the upper driving rod 211 continues to move upward, the driving arc surface 223 at the lower end of the lower driving rod 221 gradually separates from the driving protrusion 132, the elastic rod 131 gradually resets, and then the anti-falling boss 133 resets to the lower main body 120, so as to limit and protect the chip in the cavity of the lower main body 120.

[0033] During the chip transfer process, the chip is located in the internal cavity of the hand-held handle 100, and when the lower end of the protective head 130 located below the hand-held handle 100 is bumped, the chip is not directly affected, and the protection performance is good.

[0034] On the basis of the above, as shown in FIG. Figures 2 to 4 , the edges and corners of the upper and lower end faces inside the driving protrusion 132 are provided as smooth arc surfaces. The driving arc surface 223 can drive the driving protrusion 132, and the operation process is avoided from being stuck.

[0035] On the basis of the above, as shown in FIG. Figure 2 , Figure 3 and Figure 5 , the shaft centers of the upper driving rod 211, the transmission rod 212, the lower driving rod 221 and the suction rod 222 coincide and are provided with gas holes penetrating upward and downward, and the vacuum mechanism 240 is an elastic air bag fixed on the upper end of the upper driving rod 211 and communicated with the gas hole at the upper end of the upper driving rod 211. The structure is simple and convenient to operate.

[0036] On the basis of the above, as shown in FIG. Figure 2 ,Figure 3 and Figure 5 As shown in the figure, one side of the upper end of the elastic air bag of the upper driving rod 211 is provided with a pressing driving block 214 for pressing the driving of the upper driving rod 211. In the specific implementation, during operation, the slightly rear part of the thumb can be used to press the pressing driving block 214 to control the vertical relative displacement of the adsorption mechanism 200 in cooperation with the elastic member 140. When the elastic air bag needs to be controlled, the thumb tip part can be used for pressing, and after the elastic air bag is exhausted, the elastic air bag is relaxed to generate the adsorption force to adsorb the chip. After the chip is adsorbed, the elastic air bag is not pressed to adsorb the chip. The structure is simple and the operation is convenient.

[0037] On the basis of the above, Figures 1 to 5 As shown in the figure, the horizontal section of the cavity inside the upper body 110 is a regular octagon, the horizontal section of the upper driving rod 211 is a regular octagon, and the lower end of the upper driving rod 211 is located inside the upper body 110 and is limited to move in the vertical direction and cannot rotate horizontally by the upper body 110. Avoid the rotation of the adsorption mechanism 200 during the up and down movement, and facilitate the taking and placing of the chip.

[0038] The above specific embodiments further illustrate the purpose, technical scheme and beneficial effects of the present application. It should be understood that the above is only a specific embodiment of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
