[0001] The utility model relates to the technical field of semiconductor packaging, in particular to a zoomable suction pen. Background Art
[0002] In recent years, large-size semiconductor packages have continued to occupy the market. However, as the size of packaged products increases, their weight also increases, and their structures become more complex and varied, which puts higher demands on the performance of the suction pen for sucking products. In order to meet the suction needs of products of different sizes, the existing single-head suction nozzle cannot meet the variable size structure even if the nozzle is replaced with a different size. Frequent nozzle replacement is cumbersome and affects production line efficiency. Utility Model Content
[0003] The utility model aims to provide a retractable suction pen which does not need to change the head, has strong suction ability and can realize multi-point suction of products.
[0004] In order to achieve the above-mentioned utility model object, the utility model provides a retractable suction pen, including a pen body, a pressing block, a fixing rod, a lifting sleeve rod, a suction connecting rod, and a suction mechanism;
[0005] An air path control mechanism is provided on the top of the pen body, and the air path control mechanism is connected with the material suction mechanism through the pen body;
[0006] A fixing rod is arranged inside the pen body, the lifting sleeve rod is sleeved on the fixing rod, the lifting sleeve rod is connected with the pressing block, the pressing block extends out of the pen body, the bottom of the lifting sleeve rod is connected with the material suction connecting rod, and the material suction mechanism is connected below the material suction connecting rod; a side wall of the pen body is provided with a clearance groove;

[0008] Preferably, the suction nozzle is semicircular.
[0009] As a further improvement of the utility model, the number of the suction mechanisms is 2.
[0010] As a further improvement of the utility model, it also includes a connecting rod assembly, which includes a sliding frame, a first fixed rod, a moving wheel, a second fixed rod, and a moving block. The moving block is connected to the lifting sleeve rod, the moving wheel is connected to the moving block through the first fixed rod, and the moving wheel is connected to the suction mechanism through the second fixed rod; the sliding frame is rectangular, and suction mechanisms are provided on all four sides of the sliding frame, and each of the suction mechanisms is connected to the sliding rod.

[0023] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.
[0024] like Figure 1 As shown, a retractable suction pen of the utility model comprises a pen body 1, a pressing block 2, a fixing rod 3, a lifting sleeve rod 4, a suction connecting rod 5, and a suction mechanism 6;
[0025] An air path control mechanism 9 is provided on the top of the pen body 1, and the air path control mechanism 9 is connected with the material suction mechanism 6 through the pen body 1;
[0026] A fixed rod 3 is provided inside the pen body 1, and a lifting sleeve rod 4 is sleeved on the fixed rod 3. The lifting sleeve rod 4 is connected to the pressing block 2, and the pressing block 2 extends out of the pen body 1. The bottom of the lifting sleeve rod 4 is connected to the suction connecting rod 5, and the suction mechanism 6 is connected below the suction connecting rod 5; a side wall of the pen body 1 is provided with a clearance groove 11, which facilitates the opened suction connecting rod 5 to pass through the clearance groove 11, so as to avoid the inner wall of the pen body 1 interfering with the adjusted suction connecting rod 5.
[0027] There are several suction mechanisms 6, which include a one-way valve 62 and a suction nozzle 61, wherein the suction nozzle 61 is connected to the bottom of the one-way valve 62; the one-way valve 62 is connected to a sliding rod 63, and when the pressing block 2 is lifted or lowered, the lifting sleeve rod 4 is lifted or lowered along the fixed rod 3, and the suction connecting rod 5 at the bottom of the lifting sleeve rod 4 is scaled accordingly, and the one-way valve 62 can move along the sliding rod 63, and the sliding rod 63 plays a guiding role.
[0028] The one-way valve 62 is used to install the suction nozzle 61 and connect the air circuits, and is used to ensure that if one air circuit is closed or damaged, the negative pressure air circuits of other circuits will not be affected. Figure 2 As shown, the suction nozzle 61 is semicircular, and two adjacent semicircular suction nozzles 61 can be closed to reduce the gap between adjacent suction nozzles 61, so as to meet the adsorption requirements of semiconductor products 7 of smaller sizes as much as possible.
[0029] The utility model is a zoomable suction pen. When it is necessary to absorb a small-sized semiconductor product 7, the pressing block 2 is moved upward, and the lifting sleeve rod 4 moves upward accordingly. The suction connecting rod 5 rotates and drives each corresponding one-way valve 62 to move along the sliding rod 63, thereby reducing the spacing between each one-way valve. Subsequently, the air circuit is controlled by the air circuit control mechanism 9, and each suction nozzle 61 generates negative pressure. Then, each suction nozzle 61 is aligned with each suction point of the semiconductor product 7, so that the semiconductor product 7 is tightly adsorbed on the suction nozzle 61 to achieve material collection; Figure 3As shown, when it is necessary to absorb a large size or several semiconductor products 7, the button 2 is moved downward, and the lifting sleeve rod 4 moves downward accordingly, and the suction connecting rod 5 rotates and drives each corresponding one-way valve 62 to move along the sliding rod 63, increasing the spacing between each one-way valve, and then the air circuit is controlled by the air circuit control mechanism 9 to realize the suction of the suction nozzle 61. When releasing the material, the air circuit is controlled by the air circuit control mechanism 9, and the negative pressure air circuit is closed, so that the suction nozzle 61 loses the suction effect on the semiconductor product 7, and the purpose of releasing the product is achieved.
[0030] The number of suction mechanisms 6 is preferably two, and the structure is simple. The change of the distance between the two suction mechanisms 6 can be quickly controlled. The double-point adsorption structure is relatively stable and can also meet the synchronous suction requirements of the dual semiconductor products 7.
[0031] like Figure 4-5 As shown, a retractable suction pen of the utility model also includes a connecting rod assembly 8, which includes a sliding frame 81, a first fixed rod 82, a moving wheel 83, a second fixed rod 84, and a moving block 85. The moving block 85 is connected to the lifting sleeve rod 4, the moving wheel 83 is connected to the moving block 85 through the first fixed rod 82, and the moving wheel 83 is connected to the suction mechanism 6 through the second fixed rod 84; the sliding frame 81 is rectangular, and the four sides of the sliding frame 81 are provided with suction mechanisms 6, and each suction mechanism 6 is connected to the sliding rod 63.
[0032] The moving block 85 rises and falls with the lifting and lowering of the lifting sleeve rod 4, and drives the first fixed rod 82 to move on the moving wheel 83, pushing the second fixed rod 84 to move, and each suction mechanism 6 on the sliding frame 81 moves along the sliding rod 63, thereby adjusting the spacing between each suction mechanism 6 according to the adsorption requirements of semiconductor products 7 of different sizes, thereby realizing the opening or contraction of each suction mechanism 6.
[0033] Several suction mechanisms 6 are distributed on the four sides of the rectangular sliding frame 81. After being unfolded, they can absorb large-sized products. When sucking materials, four-sided suction can be achieved. Compared with double-point suction, four-sided suction is more stable and avoids individual air path instability, which leads to unstable suction and damage to the product.
[0034] like Figure 6-7As shown, the air circuit control mechanism 9 includes an air circuit switch 91, a vacuum solenoid valve 92, a vacuum diverter 93, and a plurality of air pipes 95. The suction mechanism 6 is connected to the pen body 1 through the corresponding air pipe 95. The pen body 1 is provided with an air circuit hole 94. The air pipe 95 is connected to the air circuit hole 94. The air circuit switch 91, the vacuum solenoid valve 92, and the vacuum diverter 93 are respectively connected to the pen body 1. The vacuum solenoid valve 92 is an existing miniature vacuum solenoid valve, which is used to monitor the air circuit conditions. If the air circuit is abnormal and causes the vacuum negative pressure to decrease, the vacuum solenoid valve 92 will replenish the air pressure in time and alarm to ensure the adsorption effect of the suction nozzles 61 connected to each air circuit, and prevent the adsorbed products from falling. The vacuum diverter 93 is used to divert the gas, and divert the negative pressure gas to each air pipe 95, so that each suction mechanism 6 can act independently.
[0035] The air pipe 95 is preferably a hard corrugated pipe, which is easy to install and has a shock-resistant effect, and is suitable for an installation structure with multiple pipeline diversions.
[0036] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all within the scope defined by the claims of this application.
