Description

Technical Field

[0001] This utility model relates to the field of semiconductor automation equipment technology, and in particular to an alternating semiconductor product sampling and receiving mechanism. Background Technology

[0002] With the increasing demands for product quality control in the semiconductor packaging and testing industry, automated equipment in each production process needs to have random sampling capabilities to facilitate real-time quality inspection of finished products during production. Traditional SOT bulk receiving and lead cutting equipment is equipped with only a single receiving box, which has significant drawbacks: manual sampling directly from this receiving box disrupts the normal product receiving order, and the sampling operation requires machine shutdown, significantly reducing equipment production efficiency; if the equipment is kept running continuously, it is impossible to effectively distinguish the sampled products from the normal qualified products, which can easily lead to material mixing. The existing single receiving box structure is difficult to achieve standardized online sampling inspection. The industry urgently needs a receiving box mechanism that can balance continuous production and random quality inspection. Therefore, this application provides an alternating semiconductor product sampling and receiving mechanism to meet this need. Utility Model Content

[0003] To address the technical shortcomings of existing SOT bulk material receiving and cutting equipment with a single receiving box structure, such as the inability to perform online sampling inspection without stopping the machine, easy material mixing during sampling, and reduced production capacity due to machine stoppage for sampling, this utility model provides an alternating sampling receiving box mechanism. This mechanism can complete random sampling inspection of products without interrupting normal equipment production, avoid material mixing, and ensure production cycle time.

[0004] To achieve the above objectives, this application provides the following technical solution: an alternating semiconductor product sampling and receiving mechanism, comprising a base plate, a movable material discharge plate, a drive cylinder, and a first receiving box and a second receiving box with handles;

[0005] The base plate is mounted on the mounting bracket by mounting parts. The base plate is provided with a left limiting block, a middle limiting plate and a right limiting block in sequence. The left limiting block and the middle limiting plate form a receiving cavity to accommodate the second receiving box, and the right limiting block and the middle limiting plate form a receiving cavity to accommodate the first receiving box.

[0006] The movable material discharge plate is provided with two sets of discharge ports adapted to the first material receiving box and the second material receiving box, and a material discharge slide plate is provided above the movable material discharge plate, and the material discharge slide plate is hollow.

[0007] The movable material leakage plate is slidably connected to multiple sets of guide shafts via linear bearings, and all sets of guide shafts are installed between the left limiting block and the right limiting block;

[0008] The output shaft of the drive cylinder is connected to the movable material leakage plate, and the drive cylinder is installed on the outer wall of the right limiting block;

[0009] It also includes a light receiving sensor and a light emitting sensor. The light receiving sensor is provided in two sets and is respectively provided on the left limiting block and the right limiting block.

[0010] The light emission sensors are respectively disposed in the grooves at both ends of the middle limiting plate, and the two sets of light emission sensors are respectively disposed in correspondence with the two sets of light receiving sensors.

[0011] The first receiving box, the second receiving box, the left limiting block, and the right limiting block are all provided with through holes that allow light to pass through;

[0012] The optical receiving sensor, optical emitting sensor, and drive cylinder are all electrically connected to the PLC controller.

[0013] As a preferred embodiment of this invention, shock absorbers are provided on both the left and right limiting blocks to buffer the impact of repositioning and reduce the noise of the mechanism and the wear of components.

[0014] In a preferred embodiment of this invention, two sets of corner plates are provided on the same side of the base plate, and the two sets of corner plates correspond to the two sets of receiving cavities respectively.

[0015] The corner plate is provided with a positioning block with a bayonet. Two sets of balls are arranged opposite each other on the inner wall of the bayonet. The two sets of balls are located at the ends of the positioning block and are respectively rolledly connected to the movable ends of the corresponding positioning springs. The positioning springs are installed in the inner cavity of the positioning block.

[0016] Both the first and second receiving boxes have locking blocks at their ends near the corner plate, and the two sides of the insertion end of the locking blocks have locking grooves.

[0017] In a preferred embodiment of this invention, both sets of corner plates are equipped with presence detection sensors to detect whether the receiving box is installed in place, preventing material spillage due to improper placement of the receiving box. The presence detection sensors are electrically connected to the PLC controller, and the PLC controller is electrically connected to the alarm.

[0018] In a preferred embodiment of this invention, both sets of material outlets are configured as right-angled trapezoidal structures, with the top being wider than the bottom, and the right-angled sides of the two sets of material outlets are arranged adjacent to each other.

[0019] In summary, the technical effects and advantages of this utility model are as follows:

[0020] 1. This utility model has a reasonable structure. Through the alternating switching structure of double receiving boxes and a sliding material leakage plate, online random sampling can be completed without interrupting the normal production of the equipment. This completely avoids the production capacity loss caused by downtime sampling, ensures stable production rhythm, and at the same time, qualified products and sampled products are collected in the first receiving box and the second receiving box respectively, which are completely isolated in physical space to eliminate the risk of material mixing. At the same time, it ensures that the product receiving order is not disrupted and the sampling sample data is accurate and reliable.

[0021] 2. In this utility model, the material discharge port adopts a right-angled trapezoidal structure that is wider at the top and narrower at the bottom. The large opening at the top can expand the receiving range and better receive the material falling from the upper material discharge slide plate, reducing the probability of material falling out of the discharge port due to installation errors or material bouncing. The narrow opening at the bottom can form a guiding effect on the falling material and constrain the trajectory of the material falling. The two material discharge ports are arranged adjacent to each other with right-angled sides, which can minimize the center distance between the two material discharge ports, thereby reducing the displacement stroke required to move the material discharge plate, while making full use of the plate surface space.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example: Reference Figure 1-3 An alternating semiconductor product sampling and receiving mechanism is shown, characterized in that it includes a base plate 10, a movable material discharge plate 4, a drive cylinder 11, and a first receiving box 2 and a second receiving box 3 with handles 15.

[0031] The base plate 10 is mounted on the mounting bracket 1 via the mounting component 12. The base plate 10 is provided with a left limiting block 7, a middle limiting plate 8 and a right limiting block 9 in sequence. The left limiting block 7 and the middle limiting plate 8 form a receiving cavity to accommodate the second receiving box 3, and the right limiting block 9 and the middle limiting plate 8 form a receiving cavity to accommodate the first receiving box 2.

[0032] The movable material discharge plate 4 is provided with two sets of discharge ports that are compatible with the first material receiving box 2 and the second material receiving box 3, and a material discharge slide plate 5 is provided above the movable material discharge plate 4, and the material discharge slide plate 5 is hollow.

[0033] The movable material leakage plate 4 is slidably connected to multiple sets of guide shafts 17 via linear bearings 18, and the multiple sets of guide shafts 17 are all installed between the left limiting block 7 and the right limiting block 9;

[0034] The output shaft of the drive cylinder 11 is connected to the movable material leakage plate 4, and the drive cylinder 11 is installed on the outer wall of the right limiting block 9;

[0035] It also includes a light receiving sensor 14 and a light emitting sensor 13. The light receiving sensor 14 is provided in two sets, and is respectively provided on the left limiting block 7 and the right limiting block 9.

[0036] The light emission sensors 13 are respectively set in the grooves on both sides of the middle limiting plate 8, and the two sets of light emission sensors 13 are set in correspondence with the two sets of light receiving sensors 14.

[0037] The first receiving box 2, the second receiving box 3, the left limiting block 7, and the right limiting block 9 are all provided with through holes that allow light to pass through;

[0038] The light receiving sensor 14, the light emitting sensor 13, and the drive cylinder 11 are all electrically connected to the PLC controller.

[0039] Its material leakage slide plate 5 is connected to the equipment outlet at its upper end, and initially, both sets of material leakage ports are set above the same receiving box, such as Figure 5 As shown,

[0040] During operation, the product falls directly into the discharge port through the hollow cavity of the discharge slide plate 5, and then falls from the discharge port into the second collection box 3;

[0041] A photoelectric switch is formed by using a light emitting sensor 13 and a light receiving sensor 14 to generate light that passes through the through hole in the side wall of the receiving box to form a detection light path. When the material accumulation height in the receiving box rises to the point of blocking the light path, the receiving signal of the light receiving sensor 14 is interrupted, and the PLC controller determines that the receiving box has reached the full state. At the same time, the PLC controller can receive a sampling inspection command and automatically control the drive cylinder 11 to complete the workstation switching. At the same time, the PLC controller alarms to remind personnel to replace the receiving box.

[0042] When the drive cylinder 11 is working, it drives the moving material leakage plate 4 to move laterally from the second receiving box 3 to above the first receiving box 2. At this time, the hollow cavity of the material leakage slide plate 5 coincides with the previously idle material leakage port. The product can directly enter the first receiving box 2 through this material leakage port. When this receiving box is full, the drive cylinder 11 will drive the moving material leakage plate 4 to perform a reset movement, thereby guiding the product to different receiving boxes and realizing the switching between normal material receiving and sampling material receiving.

[0043] Through the alternating switching structure of the double receiving box and the horizontally moving material leakage plate 4, online random sampling inspection can be completed without interrupting the normal production of the equipment, completely avoiding the capacity loss caused by downtime sampling and ensuring stable production rhythm.

[0044] Meanwhile, qualified products and sampled products are collected in the first receiving box 2 and the second receiving box 3 respectively, which are completely isolated in physical space to eliminate the risk of material mixing, while ensuring that the product receiving order is not disrupted and that the sampled product data is accurate and reliable.

[0045] As a preferred embodiment of this example, Figure 2 As shown, shock absorbers 16 are provided on both the left limit block 7 and the right limit block 9 to buffer the impact of displacement and reduce the noise of the mechanism and the wear of the components.

[0046] When the drive cylinder 11 moves the movable material leakage plate 4 to the end of its stroke, the movable material leakage plate 4, which has a certain moment of inertia, will have a rigid collision with the limiting block. The shock absorber 16 can be an elastic column that protrudes from the limiting surface of the limiting block in advance. Before the movable material leakage plate 4 reaches the rigid limit, it contacts its end face first. Through its own elastic deformation, it gradually absorbs the kinetic energy of the movable material leakage plate 4, converts the rigid impact into flexible deceleration, and finally makes the movable material leakage plate 4 stop smoothly.

[0047] It can effectively reduce the impact load during workstation switching, prevent fatigue cracks and damage to parts caused by repeated impacts, and eliminate the sharp mechanical noise generated by rigid collisions.

[0048] As a preferred embodiment of this example, Figure 4 As shown, two sets of corner plates 6 are provided on the same side of the base plate 10, and the two sets of corner plates 6 correspond to the two sets of receiving cavities respectively.

[0049] Angle plate 6 is provided with a positioning block 22 with a bayonet. Two sets of balls 21 are arranged opposite each other on the inner wall of the bayonet. The two sets of balls 21 are located at the ends of the positioning block 22 and are respectively rolledly connected to the movable ends of the corresponding positioning springs. The positioning springs are installed in the inner cavity of the positioning block 22.

[0050] Both the first receiving box 2 and the second receiving box 3 are provided with a locking block 19 at the end near the corner plate 6, and the two sides of the insertion end of the locking block 19 are provided with locking grooves 23.

[0051] Angle plate 6 serves as the positioning reference at the rear end of the receiving box. It cooperates with handle 15 at the front end of the receiving box to realize the pull-out assembly and disassembly of the receiving box. When the receiving box is pushed inward along the receiving cavity, the locking block 19 at the rear end of the receiving box is inserted into the slot of the positioning block 22. The guide slope at the insertion end of the locking block 19 first contacts the ball 21, squeezing the ball 21 to both sides, causing the ball 21 to compress the positioning spring in the positioning block 22 and retract. When the locking block 19 is fully inserted, the locking groove 23 on the side of the locking block 19 is aligned with the position of the ball 21. The positioning spring resets and releases its elastic force, pushing the ball 21 into the locking groove 23 to form an elastic locking, thus completing the axial positioning of the receiving box. When the receiving box is pulled outward, the pulling force overcomes the spring force, causing the ball 21 to retract inward again, which can quickly release the locking and remove the receiving box.

[0052] In the snap-fit ​​state, it can provide a stable axial positioning force to prevent the material box from shifting or falling out due to vibration during equipment operation, ensuring accurate material receiving position. With the constraint of the side-mounted limit block, it can ensure the installation position accuracy of the receiving box from multiple dimensions and avoid material spillage.

[0053] As a preferred embodiment of this example, Figure 4As shown, both sets of corner plates 6 are equipped with position detection sensors 20 to detect whether the receiving box is installed in place, preventing material spillage caused by the box not being placed in place. The position detection sensors 20 are electrically connected to the PLC controller, and the PLC controller is electrically connected to the alarm.

[0054] The in-position detection sensor 20 is installed at the corresponding detection position of the corner plate 6. It adopts the proximity detection principle. When the receiving box is fully pushed in and installed in place, the locking block 19 at the rear end of the box or the box body enters the detection range of the sensor, triggering the in-position detection sensor 20 to output an in-position signal and transmit it to the PLC controller. If the receiving box is not placed, not fully pushed in, or accidentally comes out during operation, the sensor cannot detect the box. The PLC controller will then determine that the in-position is abnormal and trigger the alarm to issue an audible and visual alarm signal. At the same time, it can also link the equipment to stop the feeding action, forming a safety interlock.

[0055] As a preferred embodiment of this example, Figure 5 As shown, both sets of the material discharge ports are configured as right-angled trapezoidal structures, with the upper part being wider than the lower part, and the right-angled sides of the two sets of material discharge ports are arranged adjacent to each other.

[0056] The material discharge port adopts a right-angled trapezoidal structure that is wider at the top and narrower at the bottom. The large opening at the top can expand the receiving range and better receive the material falling from the upper material discharge slide plate 5, reducing the probability of material falling out of the discharge port due to installation errors or material bouncing. The narrow opening at the bottom can form a guiding effect on the falling material and constrain the trajectory of the material falling. The two material discharge ports are arranged adjacent to each other with right-angled sides, which can minimize the center distance between the two material discharge ports, thereby reducing the repositioning stroke required to move the material discharge plate 4, while making full use of the plate space.

[0057] It should be noted that the optimal angle between the inclined surface of the material discharge port and the horizontal plane is 55°-65°. If the angle is too large, the closing effect of the inclined surface will be greatly weakened, and the difference in size between the upper and lower openings of the material discharge port will be minimal, which will not be able to effectively offset the deviation of the material drop point and will defeat the design purpose of the trapezoidal structure. If the angle is too small, the inclined surface will be too gentle. Although the closing effect will be enhanced, it will result in an excessively large upper opening width of the material discharge port for the same plate thickness, which will encroach on the layout space of the movable material discharge plate 4, increase the station switching stroke, and is not conducive to the compactness of the mechanism.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
