Description

Technical Field

[0001] This invention relates to the field of semiconductor technology, and in particular to a barrier separation structure, a barrier separation device, and a turret-type testing equipment. Background Technology

[0002] A turret-type testing machine is a semiconductor device with a main motor at the center and various testing stations evenly distributed around it according to the process. In existing turret-type testing machines, semiconductor products are separated one by one by a guide spring (usually a copper sheet) at the front of the feeding structure during turret loading. This structure has high requirements for the position and elasticity of the guide spring; if wear or aging is found, it needs to be replaced, and the position of the new guide spring must be calibrated before use. Inaccurate positioning or reduced elasticity of the guide spring can cause material to fall / fly, leading to frequent alarms and, in severe cases, damage to the encapsulated parts. Furthermore, the position calibration of the guide spring requires specialized debugging tools and skilled operation experience, significantly impacting production efficiency and cost. In addition, the guide spring has a complex structure, requires advanced manufacturing processes, is costly, and has a short service life.

[0003] Therefore, a new blocking separation structure, blocking separation device, and turret-type testing equipment are needed to solve the problems of high positioning requirements, difficult debugging, frequent equipment alarms, low efficiency, and high cost of existing material blocking springs. Summary of the Invention

[0007] Optionally, the pressing component includes a mounting portion and a pressing head extending outward from the mounting portion. The pressing head and the mounting portion are located on the same plane. The pressing head contacts the upper surface of the product when the pressing component descends. An oblong hole is formed at the center of the mounting portion. The long axis of the oblong hole corresponds to the lifting direction of the pressing component, and the extending direction of the pressing head corresponds to the long axis of the oblong hole.

[0008] Optionally, the pressing component includes two pressing heads, which are arranged symmetrically at the center.

[0009] Optionally, one side of the second adjusting fastener is provided with a mounting slot extending in the lifting direction. The bottom of the mounting slot is provided with an internal threaded hole. The internal threaded hole of the second adjusting fastener and the waist-shaped hole of the mounting part are fixedly connected by screws. The side of the pressure member through which the waist-shaped hole passes is provided with a positioning step. The positioning step is installed in the mounting slot.

[0010] Optionally, the pressure member must satisfy at least one of the following:

[0011] The pressure head has a straight strip-shaped structure;

[0012] The length of the pressure head is greater than or equal to 2 mm;

[0013] The thickness of the pressure head is 0.6mm to 0.8mm;

[0014] The pressure head has a chamfer on one side along its width direction, and the chamfer is 5° to 8°.

[0015] Optionally, the blocking separation structure further includes an elastic reset structure connected to the movable support and the fixed support; the elastic reset structure stores elastic potential energy during the lifting of the pressure component; the elastic reset structure also releases elastic potential energy to push the movable support to rotate in the opposite direction, thereby driving the pressure component to descend.

[0016] Optionally, the front end of the fixed bracket is provided with a boss, and the boss is provided with an internal threaded hole along the lifting direction. The internal threaded hole is used to install a limiting screw, which is used to limit the second adjusting and fixing member when the movable bracket rotates in the reverse direction.

[0017] Optionally, the rear end of the fixed bracket is provided with a U-shaped mounting structure, and the two opposite side walls of the U-shaped mounting structure along the second direction are provided with through holes. The two ends of the rotating shaft are mounted in the two through holes by bearings, and a part of the movable bracket is accommodated in the U-shaped groove defined by the U-shaped mounting structure.

[0018] Optionally, the blocking separation structure further includes a drive block connected to the movable support; the drive block is used to cooperate with the feeding structure of the turret-type testing equipment to push the drive block using the feeding structure, thereby driving the movable support to rotate, so as to lift the pressure component.

[0019] Optionally, the first adjusting fastener is located at the top of the movable bracket, the driving block is located at the bottom of the movable bracket, and the driving block has an inclined surface.

[0020] Optionally, the blocking separation structure further includes a fixing member limiting structure, which is disposed on the movable bracket and used to limit the position of the first adjusting fixing member.

[0021] Furthermore, based on the same inventive concept, the present invention also provides a blocking and separating device, which includes a feeding structure and any one of the blocking and separating structures described herein.

[0022] Before the feeding structure receives and delivers a product, the pressing component holds the product down; when the feeding structure receives and delivers a product, the movable bracket is driven to rotate by the feeding structure, so that the pressing component is lifted to release the product onto the feeding structure; after the feeding structure removes the product, the movable bracket is driven to rotate in the opposite direction, so that the pressing component descends to press down on the next product.

[0023] Furthermore, based on the same inventive concept, the present invention also provides a turret-type testing device, which includes a feeding structure and the aforementioned blocking and separating device; the blocking and separating device is installed at the front end of the feeding structure; after the feeding structure feeds the product into its front end, the blocking and separating structure presses down on the product, and then the feeding structure removes the product.

[0024] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0025] The blocking and separation structure provided by the present invention blocks and separates the product by pressing the product with a pressure component, which can increase the contact area, reduce positioning requirements, thereby simplifying the structure, reducing the processing requirements of the pressure component, reducing debugging difficulty, and improving the blocking effect and service life. This improves production efficiency, reduces production costs, and reduces or avoids the risk of frequent equipment alarms.

[0026] The pressure component in the barrier separation structure provided by this invention is made of engineering plastics, especially PEK material. Its service life can be increased several times compared with traditional barrier springs, and it is not easy to damage the plastic seal, further reducing production costs, improving production efficiency, and improving product quality.

[0027] The blocking and separating structure provided by the present invention can be equipped with two pressure heads at the same time. When one of the pressure heads is worn or aged, the other pressure head can be replaced by simply rotating the pressure component. This can effectively increase the service life of the pressure component and reduce the cost of use.

[0028] The blocking and separating structure provided by the present invention has a chamfer on one side of the pressing head along the width direction. The angle of the chamfer is 5° to 8°, so that the pressing head can effectively separate two adjacent products and press them correctly on the first product, avoiding pressing the second product, thereby increasing the reliability and effectiveness of product blocking and separating.

[0029] The blocking and separating structure provided by the present invention also includes a fixing member limiting structure. After the position of the first adjusting fixing member is adjusted, the position of the first adjusting fixing member can be limited by the fixing member limiting structure to prevent the screws on the first adjusting fixing member from loosening and causing the position of the pressure member to change.

Detailed Implementation

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0040] As described in this application, "front end" refers to the position near the main motor turntable of the turret test equipment, and "rear end" is the position opposite to "front end," meaning the position away from the main motor turntable of the turret test equipment. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Additionally, directional terms such as above, below, up, down, left, right, etc., are used relative to exemplary embodiments as shown in the figures, with "up" or "above" pointing towards the top of the corresponding figure, and "down" or "below" pointing towards the bottom of the corresponding figure.

[0041] The purpose of this invention is to provide a blocking separation structure, a blocking separation device, and a turret-type testing equipment to solve the problems of existing material blocking springs, such as high positioning requirements, difficult debugging, frequent equipment alarms, low efficiency, and high cost.

[0042] It should be noted that the turret-type testing equipment provided by the present invention is preferably a turret-type testing and sorting machine, such as an ASM edge-measuring sorting machine. The following description refers to the accompanying drawings.

[0043] Figure 1 This diagram illustrates the assembly structure of the barrier separation structure 100 according to a preferred embodiment of the present invention. Figure 2 An exploded structural diagram of the barrier separation structure 100 according to a preferred embodiment of the present invention is shown. Figure 3This diagram shows a preferred embodiment of the present invention, in which the barrier separation structure 100 is installed on one side of the front end of the feeding structure 200 of the turret-type testing equipment. Figure 4 An enlarged schematic diagram of the blocking and separating structure 100 of a preferred embodiment of the present invention installed at the feeding structure 200 is shown.

[0044] like Figures 1-4 As shown, this embodiment of the invention relates to a turret-type testing device, which includes: a blocking and separating device and a feeding structure 200; and the blocking and separating device includes a feeding structure and a blocking and separating structure 100. The blocking and separating device is installed at the front end of the feeding structure 200. During operation, after the feeding structure 200 feeds the product into its front end, the blocking and separating structure 100 can hold the product in place, and then the feeding structure can remove the product.

[0045] As those skilled in the art will understand, semiconductor products (including but not limited to IC chips) are first fed onto the main motor turntable of the turret-type testing equipment via a feeding structure 200. The feeding structure 200 generally includes a linear guide 201, which conveys the product from its rear end towards the front end near the main motor turntable. Furthermore, the feeding structure and the blocking / separating structure 100 are typically linked. The feeding structure primarily enables rapid forward and backward movement of the receiving platform and simultaneously controls the longitudinal lifting of the pressure member 5 in the blocking / separating structure 100 to release the product.

[0046] Specifically, the linear guide 201 is responsible for continuously and quickly feeding discrete products into the front end of the linear guide 201 near the main motor turntable. Before the receiving platform receives the products, the blocking and separating structure 100 first presses down the products on the front end of the linear guide 201 with the pressing member 5. When the receiving platform moves to the front end of the linear guide 201 to receive the products, the pressing member 5 in the blocking and separating structure 100 is lifted longitudinally, and the products are then transported from the linear guide 201 to the receiving platform. Subsequently, the receiving platform returns to remove the products, and then the pressing member 5 descends to press down the next product on the front end of the linear guide 201. In this way, the feeding, blocking and separating, and picking operations are repeated.

[0047] In addition to the receiving platform, the feeding structure generally includes a receiving motor and a motion mechanism (such as a cam-slider mechanism). The receiving motor drives the motion mechanism to achieve the conversion from rotary motion to linear motion. This allows for rapid forward and backward movement of the receiving platform and simultaneous control of the lifting of the pressing component 5. However, this invention does not specifically limit the feeding structure or the method of controlling the lifting of the pressing component 5. Those skilled in the art can refer to existing technologies for understanding, and further details are omitted here.

[0048] like Figure 1 and Figure 2As shown, the blocking and separating structure 100 includes a fixed bracket 1, a movable bracket 2, a first adjusting fixing member 3, a second adjusting fixing member 4, and a pressing member 5 connected in sequence. And as... Figure 3 and Figure 4 As shown, the blocking and separating structure 100 of this embodiment is installed on the front side of the linear guide rail 201, which can block incoming materials and separate them one by one.

[0049] The fixed bracket 1 is used to connect with the feeding structure 200, and the connection method is not limited. For example, a commonly used connection method is screw connection. The movable bracket 2 can be driven to rotate up and down relative to the fixed bracket 1 around the rotating shaft 6, thereby driving the pressing component 5 to rise or fall. When the pressing component 5 rises, it releases the product; when it falls, it presses down on the product. In this embodiment, the movable bracket 2 and the fixed bracket 1 are connected by the rotating shaft 6, and bearings can be installed at both ends of the rotating shaft 6 to provide stable support. The rotating shaft 6 can be arranged along a first direction or a second direction. In this embodiment, the rotating shaft 6 is arranged along the second direction. The first direction is the front-to-back direction, which is the conveying direction of the product on the linear guide rail 201, and the second direction is the left-to-right direction.

[0050] Furthermore, the first adjusting fastener 3 can be adjusted in position along a first horizontal direction, thereby adjusting the horizontal position of the pressure member 5 in the first direction. Specifically, in this embodiment, as... Figure 1 and Figure 2 As shown, the first adjusting fastener 3 has a waist-shaped hole 31, the major axis of which is parallel to the first direction. Therefore, during installation, as... Figure 3 and Figure 4 As shown, the oblong hole 31 on the first adjusting fastener 3 is used to insert a bolt (not labeled) to connect with the movable bracket 2, and the position of the first adjusting fastener 3 in the first direction can also be adjusted through the oblong hole 31.

[0051] Similarly, the second adjusting fastener 4 can be adjusted in a second horizontal direction, which is perpendicular to the first direction. This facilitates adjusting the horizontal position of the pressure member 5 in the second direction. In this embodiment, the second direction is the left-right direction. Likewise, the second adjusting fastener 4 and the first adjusting fastener 3 are connected by a bolt fitted with another oblong hole, thereby adjusting the position of the second adjusting fastener 4 in the second direction.

[0052] In addition, the pressing component 5 can adjust its position along the lifting direction, which is the vertical direction (or vertical direction).

[0053] Based on this, the working principle of the blocking and separating device provided in this embodiment is as follows: before the feeding structure receives and delivers the product, the pressing component 5 first presses down on a product corresponding to the front end of the feeding structure 200; when the feeding structure receives and delivers the product, the movable bracket 2 is driven to rotate by the feeding structure, so that the pressing component 5 is lifted and releases the product onto the feeding structure; after the feeding structure takes away the product, the movable bracket 5 is driven to rotate in the opposite direction, so that the pressing component 5 descends and presses down on the next product.

[0054] In this way, the blocking and separating structure 100 provided by the present invention presses the product with the pressure member 5 and separates the products one by one. Compared with the existing blocking and separating by the baffle spring at the front end of the product, it can increase the contact area, reduce the positioning requirements for blocking the product, thereby simplifying the structure, reducing the processing requirements of the pressure member 5, reducing the debugging difficulty, and the blocking effect is better and the service life can be greatly improved, thereby improving production efficiency and reducing production costs.

[0055] Therefore, the blocking and separating structure 100 provided by this invention reduces the requirements for the position and processing of the pressure component 5, and the blocking effect is better. It is less likely to cause material dropping / flying, reducing or avoiding the risk of frequent equipment alarms. Moreover, during debugging, no special debugging tools are required, and the experience requirements for operators are not high. Because the requirements for the pressure component 5 are reduced, its service life can be longer, and the structure can be simpler.

[0056] Preferably, the pressing component 5 is made of a non-metallic material, specifically an engineering plastic with excellent wear resistance, hardness, and toughness. Engineering plastics include, but are not limited to, PEK material. In this embodiment, the pressing component 5 is made of PEK (polyetherketone) material. PEK is a special engineering plastic with superior heat resistance, wear resistance, and corrosion resistance. Its service life (generally up to 500,000 cycles) is several times longer than traditional retaining springs, and it is less likely to damage the encapsulated body, further reducing production costs, improving production efficiency, and enhancing product quality.

[0057] like Figure 5 and Figure 6As shown, in this embodiment, the pressing component 5 is generally a block structure. Compared with traditional baffle springs, it has a simpler structure, lower processing difficulty, longer service life, and better and more accurate separation and blocking effect. The pressing component 5 may include a mounting part 51 and a pressing head 52 extending outward from the mounting part 51; the pressing head 52 and the mounting part 51 are located on the same plane, which is equivalent to the pressing component 5 being a flat plate structure. The pressing head 52 directly contacts the upper surface of the product when the pressing component 5 descends, and the pressing head 52 is configured with a shape and size that basically does not cause damage to the encapsulated body. Preferably, the pressing head 52 is a straight strip structure, which is convenient for processing and can effectively block the product.

[0058] Based on this, in order to adjust the vertical position of the pressure member 5, a waist-shaped hole 53 is provided at the center of the mounting part 51, and the long axis of the waist-shaped hole 53 corresponds to the lifting direction of the pressure member 5. The use of this waist-shaped hole 53 allows the installation height of the pressure member 5 to be adjusted when connected to the second adjusting and fixing member 4, and the adjustable distance can be reasonably set according to the actual required lifting stroke.

[0059] The pressing head 52 should have a suitable length and thickness. In this embodiment, the length L of the pressing head 52 is mainly set in conjunction with the thickness of the cover plate 202; if the length L of the pressing head 52 is too short, the vertical adjustment stroke of the pressing component 5 will be insufficient, resulting in the product not being pressed. To address this issue, preferably, the length L of the pressing head 52 is greater than or equal to 2mm. Of course, the length L of the pressing head 52 should not be too long either, otherwise, it will increase the dimension in the height direction, increasing the volume and weight.

[0060] Preferably, the thickness of the pressing head 52 is 0.6 mm to 0.8 mm, for example, 0.6 mm, 0.7 mm, or 0.8 mm. Furthermore, the thickness of the mounting portion 51 is greater than or equal to the thickness of the pressing head 52. In this embodiment, the thickness of the mounting portion 51 is 2 mm to 3 mm, preferably 2.5 mm.

[0061] Furthermore, the pressing component 5 may be configured with one or more pressing heads 52. For example... Figure 6 As shown, the pressing component 5 is equipped with only one pressing head 52. (As indicated...) Figure 5 As shown, the pressing component 5 is equipped with two pressing heads 52, which are arranged symmetrically at the center. When one of the pressing heads 52 is worn or aged, the other pressing head 52 can be replaced simply by rotating the pressing component 5, which can effectively increase the service life of the pressing component 5 and reduce the cost of use.

[0062] Regardless of its configuration, the pressure head 52 must be installed vertically during use. Therefore, the extending direction of the pressure head 52 corresponds to the major axis direction of the oblong hole 53. For example... Figure 4 and Figure 5 As shown, a cover plate 202 is installed on the linear guide rail 201. The front end of the cover plate 202 is provided with an elongated hole 2021, and a corresponding pressing head 52 on the pressing component 5 is set downward through the elongated hole 2021 of the cover plate 202 to block and separate the product below the cover plate 202.

[0063] To ensure accurate assembly of the pressure component 5, such as Figure 7 As shown, the second adjusting fixing member 4 has a mounting slot 41 extending along the lifting direction on one side. The bottom of the mounting slot 41 has an internal threaded hole 42. The internal threaded hole 42 of the second adjusting fixing member 4 and the waist-shaped hole 53 of the pressure member 5 are fixedly connected by screws. The side of the pressure member 5 through which its waist-shaped hole 53 passes is provided with a positioning step 54, which is installed in the mounting slot 41. This arrangement ensures that the pressure member 5 is assembled in place, and that one corresponding pressure head 52 can be installed vertically in place. Moreover, after rotating 180° for installation, the other pressure head 52 can also be installed vertically in place.

[0064] Return to reference Figure 6 In some embodiments, the front and rear ends of the pressure head 52 are both right angles. (Return to Reference) Figure 5 In a further improvement, the pressing head 52 has a chamfer 55 on one side along the width direction W. The angle β of the chamfer 55 is 5° to 8°, which enables the pressing head 52 to effectively separate two adjacent products, ensuring that it correctly presses onto the preceding product and avoids pressing onto the following product, thus guaranteeing the reliability and effectiveness of product separation. It should also be understood that during use, the chamfer 55 is located at the rear end of the pressing head 52.

[0065] As described above, when the receiving platform receives material, the rotation of the movable support 2 is controlled by the feeding structure. In practice, the movable support 2 can be driven to rotate by the feeding structure through various means. More preferably, such as... Figure 1 and Figure 2 As shown, the blocking and separating structure 100 further includes a drive block 7 connected to the movable support 2. The drive block 7 cooperates with the feeding structure to push the drive block 7, thereby driving the movable support 2 to rotate, so that the pressing member 5 is lifted. Optionally, the first adjusting fixing member 3 is located at the top of the movable support 2, and the drive block 7 is located at the bottom of the movable support 2. The function of the drive block 7 is to convert linear motion in other directions into vertical motion. This motion conversion can be achieved in various ways known to those skilled in the art, and the present invention is not limited thereto.

[0066] For the drive block 7, a simpler approach is to directly configure it as a wedge, using the inclined surface of the wedge to convert the linear motion in the first direction into vertical motion. The drive block 7 and the movable support 2 are an integral structure, meaning they are machined as a single piece. In other embodiments, the drive block 7 and the movable support 2 can be connected by welding, riveting, or bolting.

[0067] Furthermore, the reverse rotation of the movable support 2 is mainly achieved through elastic force to realize automatic reset. For example... Figure 4 As shown, the blocking separation structure 100 also includes an elastic reset structure 8 connected to both the movable support 2 and the fixed support 1; the elastic reset structure 8 stores elastic potential energy during the lifting of the pressing component 5, and releases elastic potential energy when the feeding structure takes away the product and returns, thereby pushing the movable support 2 to rotate in the opposite direction, and thus driving the pressing component 5 to descend.

[0068] The elastic reset structure 8 can be located at the rear end of the movable bracket 2 and the fixed bracket 1, and its point of action is a certain distance from the rotating shaft 6. Specifically, the elastic reset structure 8 and the driving block 7 are distributed on both sides of the rotating shaft 6, and their directions of action are exactly opposite, so that the movable bracket 2 can be pushed upward by the driving block 7 and lowered by the elastic reset structure 8.

[0069] Preferably, the elastic reset structure 8 includes a reset spring (not shown) and a guide member 81 (see [reference]). Figure 4 A guide member 81 connects the movable bracket 2 and the fixed bracket 1, and the return spring is sleeved on the guide member 81. The guide member 81 can be a screw, a pin, or other various structures. In this embodiment, the guide member 81 is a screw, and the return spring is positioned between the movable bracket 2 and the fixed bracket 1. During installation, the guide member 81 is inserted into the return spring from the top of the movable bracket 2, serving to guide and fix the return spring.

[0070] like Figures 1 to 4 As shown, in some embodiments, the front end of the fixed bracket 1 is provided with a boss 11, and the boss 11 is provided with an internal threaded hole 12 along the lifting direction. The internal threaded hole 12 is used to install a limiting screw 9. The limiting screw 9 is used to limit the position of the second adjusting fixing member 4 when the movable bracket 2 rotates downward in the reverse direction, that is, to limit the downward distance of the movable bracket 2, to ensure that the pressure member 5 can press the product, and that the pressure of the pressure member 5 is appropriate, neither too high nor too low, reducing the risk of product damage. It should also be understood that the use of the limiting screw 9 is also beneficial to adjust the limiting height, so that the limiting height can change with the position of the limiting screw 9, making the limiting method more flexible and convenient. However, in other cases, the limiting screw 9 can be omitted, and the boss 11 can directly limit the position of the second adjusting fixing member 4.

[0071] Optionally, the rear end of the fixed bracket 1 is provided with a U-shaped mounting structure 13, and the U-shaped mounting structure 13 has through holes 14 on both opposite sidewalls along the second direction. Thus, both ends of the rotating shaft 4 are mounted in the two through holes 14 via bearings, and a portion of the movable bracket 2 can be accommodated within the U-shaped groove defined by the U-shaped mounting structure 13. This helps to reduce the height and volume of the entire blocking and separating structure 100.

[0072] Considering the possibility of screws loosening after the first adjusting fixing member 3 is adjusted, in some embodiments, the blocking and separating structure 100 further includes a fixing member limiting structure 10, which is disposed on the movable bracket 2 and used to limit the position of the first adjusting fixing member 3, preventing the screws (not labeled) on the first adjusting fixing member 3 from loosening and causing the position of the pressure member 5 to change. Preferably, the fixing member limiting structure 10 includes a locking screw 101 and a locking nut 102, and the top of the movable bracket 2 is provided with a base 21. One end of the locking screw 101 passes through the base 21 and abuts against the rear end of the first adjusting fixing member 3, and then the locking nut 102 is used to lock the locking screw 101 and the movable bracket 2. At this time, the position of the locking screw 101 can be adjusted according to the position of the first adjusting fixing member 3, and the limiting method is more flexible and convenient.

[0073] As can be seen, compared with the prior art, the blocking and separation structure 100 provided by the present invention uses a different structure and method from the existing baffle spring to block and separate the product. The whole structure is simple, easy to debug, has a good blocking effect, is not easy to damage the plastic seal, has a long service life, and can greatly reduce production costs, improve production efficiency, and enhance product quality.

[0074] Furthermore, it is understood that although the present invention has been disclosed above with reference to preferred embodiments, these embodiments are not intended to limit the present invention. For any person skilled in the art, many possible variations and modifications can be made to the technical solutions of the present invention based on the disclosed technical content, or equivalent embodiments can be modified accordingly, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the present invention shall still fall within the scope of protection of the present invention.
