Description

Technical Field

[0001] The present application relates to the field of packaging equipment, and in particular to a resin column weighing mechanism. Background Art

[0002] Typical automated chip packaging equipment requires resin material. After a robot delivers the strips to a preheating station, to maximize machine efficiency, the resin must be precisely transported to a designated mechanism to enter the mold along with the strips. Substandard resin can negatively impact strip processing efficiency during the next transport. Therefore, as the loading robot arrives, a resin weighing mechanism has already screened qualified resin and moved it in an orderly manner.

[0003] The existing resin weighing mechanism operates by using a pneumatic cylinder to drive an air gripper to grip the resin. The position-limiting gripper forces the resin to move in an orderly manner on the resin guide plate. The resin is then detected for presence, and two vertical handling claws transport the resin to the weighing claws. If the weighing test passes, the pneumatic cylinder controls the resin lifting claw to raise, assisting the resin handling claws in gripping the resin through the weighing claws. If the test fails, the gripper retreats slightly and discards the resin into a waste bin. The two resin transports are spaced closely together, and if a jam occurs, the resin on the guide plate cannot be removed in time, resulting in transport halts and reduced work efficiency. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a resin row weighing mechanism to solve the problem in the prior art that the spacing between unqualified resins is compact, and when a jam occurs, the resin on the guide plate cannot be removed in time, resulting in transportation being stopped and affecting work efficiency.

[0005] Based on this, the utility model provides a resin whole-row weighing mechanism, including a transport channel, a weighing unit, a first limiting device, a second limiting device and a transport component, the transport channel is extended along the movement direction of the resin, the forward direction of the resin in the transport channel is defined as the front, and the inlet end of the resin in the transport channel is defined as the rear, and the weighing unit is arranged at the front end of the transport channel; the first limiting device is located at the front end of the weighing unit, and the first limiting device can block or open the transport channel; the second limiting device is located at the rear end of the weighing unit, and the second limiting device can block or open the transport channel; the transport component is arranged above the transport channel and can move back and forth along the transport direction of the resin, and a grabbing component is provided on the transport component, which can grab the resin in the transport channel; a waste delivery port is provided between the second limiting device and the weighing unit.

[0006] Furthermore, the transport assembly includes a guide rail and a mounting frame slidably mounted on the guide rail, and the grabbing assembly includes two resin transport claws spaced apart on the mounting frame, and the two resin transport claws can slide on the guide rail along with the mounting frame.

[0007] Furthermore, the weighing unit includes a weighing claw, and a weighing sensor is provided below the weighing claw.

[0008] Furthermore, the weighing unit further comprises a resin lifting claw, which is arranged in the weighing claw and can move up and down in a vertical direction to separate the resin from the reference surface of the weighing unit.

[0009] Furthermore, the resin column weighing mechanism further includes a limiting jaw, which can be gathered or spread out in the transport channel, and the limiting jaw is arranged at the rear end of the second limiting device.

[0010] Furthermore, the resin column weighing mechanism also includes a light alignment device, which is arranged at the rear ends of the first limit device and the second limit device, and the light alignment device includes light alignment sensors respectively arranged on the left and right sides of the transportation channel.

[0011] Furthermore, sensor fixing blocks are provided on the left and right sides of the transport channel, and the light sensor is arranged in the sensor fixing blocks.

[0012] Furthermore, the first limiting device and the second limiting device both include a stopper and a driver, and the driver can drive the stopper to rotate to the front end in the direction of resin movement.

[0013] Furthermore, the resin column weighing mechanism further includes a flip table, which is arranged at the rear end of the weighing unit and can swing up and down within a certain range.

[0014] Furthermore, a waste collection box is provided below the waste delivery port.

[0015] The resin column weighing mechanism of this utility model employs a first limiter and a second limiter at each end of the weighing unit. These two limiters form a closed space, ensuring that only one resin is weighed on the weighing unit at any given time. This design not only improves weighing accuracy but also avoids errors caused by multiple resins entering the weighing unit simultaneously.

[0016] In actual operation, once the resin enters the weighing unit, the first and second limiters immediately close, creating a stable weighing space. The weighing unit houses a high-precision sensor that monitors the resin's weight in real time. If the resin's weight does not meet the preset standard, it is deemed unacceptable. At this point, a transport component activates, transporting the unacceptable resin to a dedicated disposal port, preventing it from entering subsequent production stages.

[0017] Furthermore, the system specifically considers potential resin jams during transport. Because the spacing between resins is precisely controlled, jams caused by close spacing between resins can be effectively avoided, even on high-volume production lines. Even in the rare event of a jam, the system's rapid response mechanism allows for prompt removal of the jammed resin, preventing the entire transport chain from being halted due to a single resin issue and ensuring continuous and efficient production lines.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of the embodiments.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0034] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0035] Figures 1 to 3The resin column weighing mechanism provided in the embodiment of the present application includes a transport channel, a weighing unit 300, a first limit device 500, a second limit device 600 and a transport assembly 200. The transport channel extends along the movement direction of the resin. Specifically, the resin column weighing mechanism includes a guide plate 400, which extends along the resin transport direction. The transport channel is a transport space formed on the guide plate 400. A transport channel for transporting resin is formed in the middle of the guide plate 400. The guide plate 400 is the basic part of the resin column weighing mechanism. The guide plate 400 extends along the resin transport direction to form a dedicated transport channel. This transport channel not only provides a clear transport path for the resin, but also guides the transport of the resin, ensuring that the resin can move according to a predetermined trajectory. For ease of description, the forward direction of the resin in the transport channel is defined as the front, and the end where the resin enters the channel is defined as the rear.

[0036] Furthermore, a weighing unit 300 is positioned at the front end of the guide plate 400. The weighing unit 300 is the core component of the resin column weighing mechanism and is positioned at the front end of the guide plate 400 to perform weighing and detection at appropriate times during the resin transportation process. Preferably, the weighing unit 300 typically includes a high-precision sensor and data processing system, capable of monitoring the resin weight in real time and converting it into accurate data for subsequent production control and quality monitoring.

[0037] The first limiting device 500 is located at the front end of the weighing unit 300 and can block or open the transportation channel; the second limiting device 600 is located at the rear end of the weighing unit 300 and can block or open the transportation channel.

[0038] The main function of the limiter is to block the resin transport channel to prevent the resin from moving further. The limiter can open the channel to allow the resin to continue to move forward. This design ensures the accuracy of the weighing process and the controllability of the resin movement.

[0039] The transport component 200 is arranged above the transport channel and can move back and forth along the transport direction of the resin. The transport component 200 is provided with a grabbing component, which can grab the resin in the transport channel; a waste delivery port is provided between the second limiting device 600 and the weighing unit 300.

[0040] The resin column weighing mechanism of the present invention employs a first stopper 500 and a second stopper 600 disposed at both ends of the weighing unit 300. These two stoppers create a closed space, ensuring that only one resin column is weighed and tested on the weighing unit 300 at any given time. This design not only improves weighing accuracy but also avoids errors caused by multiple resins entering the weighing unit 300 simultaneously.

[0041] In actual operation, the second limiting device 600 limits the resin's position, and the gripping assembly grabs the resin. Once the resin enters the weighing unit 300, the first limiting device 500 closes, creating a stable weighing space. The weighing unit 300 has a built-in high-precision sensor that monitors the resin's weight in real time. If the resin's weight does not meet the preset standard, it is deemed unqualified. At this point, the transport assembly 200 immediately activates and transports the unqualified resin to a dedicated waste disposal port, preventing unqualified products from entering subsequent production processes.

[0042] Furthermore, the system specifically considers potential resin jams during transport. Because the spacing between resins is precisely controlled, jams caused by close spacing between resins can be effectively avoided, even on high-volume production lines. Even in the rare event of a jam, the system's rapid response mechanism allows for prompt removal of the jammed resin, preventing the entire transport chain from being halted due to a single resin issue and ensuring continuous and efficient production lines.

[0043] Furthermore, the transport assembly 200 includes a guide rail and a mounting frame 210 slidably mounted on the rail. The gripping assembly includes two resin-handling claws 220 spaced apart on the mounting frame 210. The two resin-handling claws 220 are capable of sliding along the guide rail along with the mounting frame 210. The transport assembly 200 primarily consists of the guide rail and the mounting frame 210 slidably mounted on the rail. This design allows the mounting frame 210 to move smoothly in a straight line along the rail, thereby achieving rapid and stable transport of resin.

[0044] Furthermore, the two resin handling claws 220 can slide on the guide rail along with the mounting frame 210, thereby achieving precise handling of the resin. Through this design, the resin handling claws 220 can move flexibly on the guide rail, and can efficiently complete both the forward delivery of the resin to the weighing unit 300 and the backward delivery of the resin to the next station. Specifically, due to the provision of two resin handling claws 220, this design realizes the ability of the two claws to work together. When one handling claw transports the resin that has passed the weighing to the next station, the other handling claw can simultaneously place new resin on the weighing unit 300. This synchronous operation greatly improves detection efficiency because it allows for continuous weighing and handling of the resin in an uninterrupted process.

[0045] Furthermore, this dual-claw design offers a high degree of flexibility: if one resin-handling claw 220 encounters a problem while weighing or handling, the other can continue to operate, ensuring continuous operation of the entire system and reducing downtime due to single component failure.

[0046] In an optional embodiment of the present invention, the weighing cell 300 is further provided with a resin lifting claw 320 capable of vertically moving up and down to free the resin from the reference surface of the weighing cell 300. Specifically, the resin lifting claw 320 is a set of mechanical arms installed within the transport channel. Their primary function is to lift the resin from the weighing cell 300. The lifting of the resin lifting claw 320 assists the resin handling claw 220 in gripping the resin. The primary function of these mechanical arms is to provide necessary assistance during the resin handling process. When the resin needs to be transferred from the weighing cell 300 to another location, the resin lifting claw 320 rises, lifting the resin from the reference surface of the weighing cell 300 so that the resin handling claw 220 can more easily grip the resin. The advantage of this design is that the raising action of the resin lifting claw 320 can be synchronized with the movement of the resin handling claw 220. When the resin handling claw 220 reaches the weighing cell 300 and completes weighing, the resin lifting claw 320 rises synchronously, allowing the resin to be smoothly gripped by the handling claw. This coordinated action not only improves the stability of resin handling but also reduces resin damage and weighing errors caused by unstable factors during handling. In practical applications, the design of the resin lifting claw 320 can be adjusted according to the size and weight of the resin to accommodate resins of different specifications. This flexibility enables the resin column weighing mechanism of the present invention to be widely used in the production and testing of various resin products.

[0047] In an optional solution of an embodiment of the present invention, the weighing unit 300 includes a weighing claw 310 and a resin lifting claw 320. A weighing sensor is provided below the weighing claw 310. The resin lifting claw 320 is arranged inside the weighing claw 310. The resin lifting claw 320 can move up and down in the vertical direction to separate the resin from the reference surface of the weighing unit 300. The weighing claw 310 is a core component of the resin column weighing mechanism, and it is responsible for accurately measuring the weight of the resin. The weighing unit 300 is exquisitely designed, and the weighing claw 310 and the weighing sensor work together to achieve fast and accurate weighing. Among them, the weighing sensor is located below the weighing claw 310, and it is responsible for detecting the weight of the resin and converting it into an electrical signal. The weighing sensor is generally characterized by high sensitivity and a wide range, and can quickly respond to changes in the weight of the resin and provide accurate readings even when the resin passes through quickly. Preferably, the weighing claw 310 is generally made of corrosion-resistant and wear-resistant materials to adapt to various environmental conditions that may be encountered during the resin production process.

[0048] Specifically, the rapid response of the weighing unit 300 is crucial to improving production efficiency. As the resin passes through the weighing claws 310, the load cell quickly detects the weight change and transmits the signal to the control system. This rapid response ensures that the weighing process does not become a bottleneck in the production process.

[0049] In summary, the weighing unit 300 in the resin column weighing mechanism achieves fast, accurate, and stable weighing through its carefully designed weighing claws 310 and load cells, as well as its secure weighing module fixation. This design not only improves production efficiency but also ensures consistent product quality.

[0050] Furthermore, the resin column weighing mechanism also includes a limiting jaw 800, which can be gathered or spread within the transport channel. The limiting jaw 800 is located at the rear end of the second limiting device 600. The limiting jaw 800 can limit the resin at the rear end of the second limiting device 600. Under normal circumstances, the limiting jaw 800 clamps the second resin near the second limiting device, thereby facilitating the resin handling jaw 220 to grasp the resin near the second limiting device 600. The limiting jaw 800 and the resin handling jaw 220 move synchronously to complete the transport of the resin.

[0051] Specifically, the main function of the limiting jaws 800 is to perform precise limiting control on the resin located at the rear end of the second limiting device 600. This design ensures the stability of the resin during the weighing process, while also improving the efficiency and accuracy of resin handling. The design of the limiting jaws 800 is very clever, and they can clamp the second resin near the second limiting device 600 when needed. This setting makes it easier for the resin handling jaws 220 to clamp the resin located near the second limiting device 600. When the resin handling jaws 220 slide on the guide rail and reach the second limiting device 600, the limiting jaws 800 will automatically clamp the resin, providing stable support for the clamping action of the resin handling jaws 220.

[0052] In practical applications, the design of the limiting jaws 800 can also be adjusted according to the size and weight of the resin to accommodate resins of different specifications. This flexibility enables the resin column weighing mechanism of the present invention to be widely used in the production and testing of various resin products.

[0053] Furthermore, the resin column weighing mechanism also includes a light alignment device 900, which is arranged at the rear end of the first limit device 500 and the second limit device 600. It is intended to improve the accuracy and automation level of the resin transportation and weighing process. When the light alignment device 900 detects that there is no resin, an alarm will be issued. Furthermore, the light alignment device 900 includes light alignment sensors respectively arranged on the left and right sides of the transportation channel. The setting of the light alignment sensor not only enhances the detection capability of the system, but also provides effective technical support for the positioning and monitoring of the resin, avoiding empty stroke operation. The setting of the light alignment sensor helps to monitor the transportation status of the resin in real time. If the sensor detects that there is a vacancy in the resin, the system can take immediate action. This real-time monitoring and rapid response mechanism improves the continuity and efficiency of the production process.

[0054] Specifically, sensor fixing blocks are provided on the left and right sides of the transport channel, and the alignment sensor is arranged in the sensor fixing blocks. In order to ensure the stability and accuracy of the alignment sensor, sensor fixing blocks are specially designed on the left and right sides of the transport channel. These fixing blocks provide a stable mounting platform for the alignment sensor, ensuring that the alignment sensor will not be displaced or vibrated during the resin transportation process, thereby ensuring the stability of the detection signal. The design of the sensor fixing block can also protect the sensor from the impact and wear that may occur during the resin transportation process. Furthermore, the design of the sensor fixing block allows operators to easily adjust and maintain the alignment sensor. Since the sensor is fixed in an easily accessible location, when the sensor needs to be calibrated or replaced, the operation can be carried out quickly, reducing maintenance time and cost.

[0055] In summary, the light sensors arranged opposite to each other on the left and right sides of the transport channel, by being integrated into the sensor fixing block, not only improve the detection accuracy and stability of the resin column weighing mechanism, but also enhance the flexibility, safety and production efficiency of the system.

[0056] Furthermore, both the first and second stoppers 500 and 600 include a stopper and a driver. The driver is capable of rotating the stopper to the front of the resin's direction of movement. The stopper, via a stopper lever, moves in front of the resin, limiting the position of the weighed resin. This facilitates the movement of the resin-carrying claw 220, which grips the resin, to a predetermined position. The movement of the resin-carrying claw 220 coordinates with the action of the stopper, ensuring stability and safety of the resin during the weighing process.

[0057] Optionally, the drive may be electric, pneumatic or hydraulic, depending on the design requirements and operating environment of the entire resin column weighing mechanism.

[0058] Furthermore, the resin column weighing mechanism also includes a flip table 700, which is arranged at the rear end of the weighing unit 300 and can swing up and down within a certain range. The swingable design of the flip table 700 makes it more convenient to change the type of resin.

[0059] In an optional embodiment of the present invention, the tilting table 700 is mounted on a bearing mount located on the frame 100. The bearing mount provides a secure support, ensuring stability and rigidity during the tilting operation, while reducing vibration and deformation caused by load fluctuations. Furthermore, the design of the bearing mount simplifies the installation and maintenance of the tilting table 700. Because the bearing mount can be pre-assembled, on-site installation only requires positioning and securing, reducing installation time and improving efficiency. Furthermore, the use of the bearing mount reduces bearing wear and extends its service life. Furthermore, the structural design of the bearing mount reduces bearing damage caused by improper installation, thereby improving the reliability of the entire machine. Furthermore, the design of the bearing mount allows the tilting table 700 to swing up and down quickly within a certain range, facilitating the rapid removal of resin buildup, thereby reducing machine downtime and improving overall efficiency. Furthermore, the precise design of the bearing mount ensures uniform load distribution on the bearings, reducing additional stress caused by improper installation or improper axial force distribution, thereby extending the bearing's service life.

[0060] In summary, the flip table 700 is fixed to the frame 100 by radially installing bearing fixing seats at both ends of the bearings, which not only improves the stability and working efficiency of the machine, but also enhances the safety and reliability of the machine. At the same time, it also simplifies the installation and maintenance process and reduces safety hazards in production.

[0061] Furthermore, a waste collection box is located below the waste inlet. If resin accumulates or becomes stuck, the resin handling claw 220 empties the resin into the waste box below for centralized collection, ensuring operational efficiency and machine safety. The waste collection box facilitates waste collection and disposal.

[0062] During operation, the pneumatic cylinder drives the pneumatic claws to clamp the resin, and the limiting claws 800 make the resin move in an orderly manner on the resin guide plate 400, and then the presence or absence of resin is detected. The resin is transported to the weighing claws 310 in an orderly manner through the two resin transporting claws 220. After the weighing test is qualified, the cylinder controls the resin lifting claws 320 to rise to assist the resin transporting claws 220 in clamping the resin and transporting it to the next process. If it fails, the resin transporting claws 220 will retreat slightly and throw the resin into the waste box.

[0063] Before operation, adjust the resin guide plate 400 to a horizontal position, secure the flip table 700 at both ends of the central axis support, install the air grippers, adjust the position of the limit jaws 800, and check the operating status of the resin handling claw 220 on the guide rail. Then, install the weighing claw 310, resin lifting claw 320, and various sensors. Adjust the operating speed of the handling claws based on the efficiency of the weighing sensor detection. During operation, the resin is arranged on the guide plate 400, and the limit jaws 800 control the order in which each resin enters the detection area. When the detection area detects the presence of resin, the resin handling claw 220 assembly places the tested resin into the weighing claw 310. At the same time, the resin lifting claw 320 lifts the resin on the weighing unit 300. Another resin handling claw 220 picks up the weighed resin and passes it through the guide plate 400, completing the weighing process.

[0064] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.

[0065] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art.
