DETAILED DESCRIPTION

[0031] The present invention is further described below with reference to specific embodiments:

[0032] The device for preventing leakage and wrong installation is used to correctly install the material to be installed on the workpiece 7, such as Figure 1 As shown, the anti-leakage and mis-installation device described in this patent includes several storage bins 1, several loading bins 2, several material stoppers 3 and a controller; wherein, the anti-leakage and mis-installation device described in this patent is used in conjunction with a tool 9, such as Figure 4 As shown, the tooling 9 includes a base and several clamps mounted on the base, which secure the workpiece 7. The tooling 9 is equipped with an installation detection assembly for detecting the installation status of the material to be installed on the workpiece 7. The installation detection assembly includes several sensors. In this embodiment, the workpiece 7 is a shell, on which several joints need to be manually installed.

[0033] The anti-leakage and mis-installation device will be arranged next to the tooling 9, wherein the storage bin 1 is used to place the material to be installed, and different storage bins 1 are used to place different materials to be installed; the loading bin 2 is located on one side of the storage bin 1, and several loading bins 2 correspond to the several storage bins 1 one by one, which are used to place the material to be installed sent from the storage bin 1 to the corresponding loading bin 2, and the operator can take the material to be installed located in the loading bin 2 for assembly; each loading bin 2 is provided with the material taking limiter 3, and the material taking limiter 3 has an open state and a closed state. In the open state, the material taking limiter 3 no longer restricts the taking of the material to be installed in the loading bin 2, and in the closed state, the material taking limiter 3 restricts the taking of the material to be installed in the loading bin 2; the controller is used to control the material taking limiter 3 to enter the open state or the closed state according to the installation status detected by the installation detection component.

[0034] like Figure 1-3 As shown, the storage bin 1 and the loading bin 2 in this patent are actually an inclined channel structure with a "U"-shaped cross-section, and several storage bins 1 are arranged in sequence, and the storage bin 1 and the loading bin 2 are connected front to back in sequence to form a whole, and a first feeding channel 11 and a second feeding channel 21 connected to each other are provided on the storage bin 1 and the loading bin 2. The first feeding channel 11 and the second feeding channel 21 are used to place the materials to be installed, and the materials to be installed located in the storage bin 1 can be directly fed into the loading bin 2 under the action of external force or its own gravity. In order to limit the entry of the materials to be installed in the loading bin 2, a feeding limiter 4 is provided between the first feeding channel 11 and the second feeding channel 21 to connect or block the first feeding channel 11 and the second feeding channel 21.

[0035] Combine Figure 1 、 3As shown, in order to facilitate the manufacture of the storage bin 1 and the loading bin 2, the storage bin 1 and the loading bin 2 in this patent are manufactured by sequentially setting dividing strips on a bottom plate to form a plurality of "U"-shaped channel structures, and the storage bin 1 and the loading bin 2 are directly connected into a whole, separated by the feeding limiter 4, so as to facilitate the transportation of the materials to be installed. In addition, the anti-leakage and mis-installation device also includes a base 5, the left and right ends of the base 5 are provided with connecting arms 51, the lower ends of the storage bin 1 are rotatably connected to the connecting arms 51, and a telescopic rod 52 is provided at the bottom of the other end of the storage bin 1, the telescopic rod 52 is located under the bottom plate of the storage bin 1, and adopts a screw nut structure to achieve lifting and lowering, and supports one end of the storage bin 1 through the telescopic rod 52, and the storage bin 1 is rotated around the connecting arm 51 by adjusting the telescopic rod 52, so that the storage bin 1 is tilted. In the tilted state, the materials to be installed in the storage bin 1 can slide directly into the upper bin 2 by gravity, thereby facilitating the transportation of the materials to be installed.

[0036] In addition, in order to further improve the conveying efficiency, the present invention further includes a vibrator 53, which is arranged at the bottom of the storage bin 1, and a vibration gap is provided at the rotation connection point between the telescopic rod 52 and the vibrator 53 or / and the base 5, such as Figure 3 As shown, a fisheye bearing is provided on the rotating connection point between the telescopic rod 52, the vibrator 53 and the base 5, which is used to swing the storage bin 1 around the connecting arm 51 through the fisheye bearing to transport the material to be installed in the storage bin 1, that is, the vibrator 53 is fixed on the bottom plate of the storage bin 1, and the vibration process will cause the storage bin 1 and the connecting arm 51 to shake and swing, so that the material to be installed in the storage bin 1 is gradually shaken into the upper bin 2.

[0037] like Figure 3 As shown, the storage bin 1 is provided with a mounting frame 41, and the feed stopper 4 includes a plurality of pressure blocks 42 that are lifted and lowered on the mounting frame 41. The mounting frame 41 is in the shape of an elongated strip, spanning above the storage bin 1 and the upper feed bin 2. The left and right ends of the mounting frame 41 are connected to the upper surface of the storage bin 1 by screws. The mounting frame 41 is provided with a cylinder, which drives the pressure blocks 42. When the pressure blocks 42 are pressed downward, they position the material to be installed below them, and the positioning of the material to be installed limits the transportation of the material to be installed in the storage bin 1.

[0038] By controlling the feed stopper 4, a specified amount of material can be fed into the loading bin 2. During the initial installation phase, the feed stopper 4 rises, allowing the material to be installed in the storage bin 1 to enter the loading bin 2 and fill it up. The feed stopper 4 then descends to restrict further entry of the material to be installed, allowing assembly of the workpiece 7 to begin.

[0039] The control method is specifically as follows:

[0040] S1: The material stoppers 3 that control the taking of the same material to be installed and the sensors that detect the material to be installed are divided into a group and numbered 1, 2, 3, ... according to the corresponding group number;

[0041] S2: Setting the opening order of the material reclaiming limiter 3 through the controller;

[0042] S3: After the workpiece is installed on the fixture 9, the No. 1 material stopper 3 is opened, allowing the operator to take the corresponding amount of No. 1 material to be installed;

[0043] S4: If all No. 1 sensors recognize that the materials to be installed are in place, the controller sends a signal; the No. 2 material stopper 3 opens, allowing the operator to take the corresponding amount of No. 2 materials to be installed, otherwise the next step will not be performed;

[0044] S5: If all No. 2 sensors recognize that the material to be installed is in place, the controller sends a signal;

[0045] S5: The No. 3 material taking restriction is opened, allowing the operator to take the corresponding number of No. 3 materials to be installed, otherwise the next operation will not be carried out;

[0046] S6: proceed in the set order until all sensors in the last group recognize that the materials to be installed are in place, and the assembly of all materials to be installed is completed.

[0047] Among them, if all sensors of the last group recognize that the materials to be installed are installed in place, the controller sends a signal and the No. 1 material stopper 3 opens, allowing the operator to take the corresponding amount of No. 1 materials to be installed, and the cycle continues in sequence.

[0048] like Figure 4 As shown, the workpiece 7 in this embodiment is provided with several installation positions, each installation position can be installed with the same type of material to be installed, or different materials to be installed. Figure 4 , Figure 4There are seven mounting positions, each of which requires installation of four types of materials to be installed, resulting in four distinct installation areas. Each material to be installed has a different color for easy identification by the operator. In this embodiment, the first material to be installed 61, the second material to be installed 62, the third material to be installed 63, and the fourth material to be installed 64. Two of each of the first material to be installed 61, the second material to be installed 62, and the third material to be installed 63 need to be installed, while only one of the fourth material to be installed 64 needs to be installed. These materials are installed in four different loading bins 2 and correspond one-to-one to the installation areas. Accordingly, the workpiece 7 is distinguished into a first mounting position 71, a second mounting position 72, a third mounting position 73, and a fourth mounting position 74. At this time, the reclaiming stopper 3 where the first material to be installed 61 is located and the first installation position 71 is numbered 1, the reclaiming stopper 3 where the second material to be installed 62 is located and the second installation position 72 is numbered 2, the reclaiming stopper 3 where the third material to be installed 63 is located and the third installation position 73 is numbered 3, and the reclaiming stopper 3 where the fourth material to be installed 64 is located and the fourth installation position 74 is numbered 4.

[0049] Before the workpiece 7 is installed, the operator will write the assembly sequence of the area to be installed into the controller. When the workpiece 7 starts to be installed, the corresponding assembly sequence is executed, and the corresponding material removal limiter 3 is controlled to limit it. For example, the first material to be installed 61 is installed first, and then the second material to be installed 62 is installed, and so on. Specifically, at the beginning of the installation, the first material to be installed 61 needs to be installed. At this time, the material removal limiter 3 at the first material to be installed 61 is in the open state, that is, the No. 1 material removal limiter 3 is open, and the material removal limiters 3 on the remaining materials to be installed are in the closed state; in this embodiment, since the loading bin 2 is a channel structure, an opening is formed above it for the operator to grab the material to be installed, and the material removal limiter 3 includes a sliding limit rod for sliding onto the opening to limit the use of the material to be installed in the loading bin 2; the limit rod is driven by the cylinder, and when it is extended, it blocks the opening, which plays a certain degree of limitation to prevent the material to be installed therein from being taken out.

[0050] At this time, the operator can only take the first material to be installed 61 in the corresponding loading bin 2 and install it on the current area to be installed. In this embodiment, a sensor corresponding to each installation position is provided on the tooling 9. The sensor is a photoelectric switch. Take the first material to be installed 61 as an example. When installing the first material to be installed 61, if the operator installs the first material to be installed 61 on the first installation position 71, the sensor on the first installation position 71 detects the corresponding material to be installed. It should be noted that the first installation position 71 can have multiple, multiple first installation positions 71 in one area. When the first material to be installed 61 is required to be installed on each first installation position 71, the installation program in the controller will enter the next step. At this time, the material removal limiter 3 at the second material to be installed 62 enters the open state, and the material removal limiter 3 at the first material to be installed 61 enters the closed state. At this time, the operator can install the second installation material 62. In this way, the operator will strictly follow the corresponding order to achieve installation, so that the phenomenon of wrong installation or missing installation will not occur, thereby effectively reducing the production of defective products and increasing the quality of real test products.

[0051] If a misassembly occurs during assembly, i.e., when the first material to be installed 61 is installed in the second or third installation position 72 or 73, the sensor at the second or third installation position 72 or 73 will detect the first material to be installed 61, indicating a misassembly. The controller will then activate an alarm to alert the operator of the misassembly and the need for prompt correction. The alarm can be a buzzer or indicator light. In practice, an alarm is not required because the order in which the components on the workpiece 7 are installed is pre-set. The next material to be installed cannot be removed until the current one is completed. Furthermore, the different colors of the materials themselves will indicate to the operator which installation position to select.

[0052] After all the materials to be installed on the workpiece 7 are installed, all the loading bins 2 are empty. At this time, the feeding stopper 4 will work to feed the corresponding materials into the loading bin 2, and complete the feeding before the next workpiece 7 is assembled, and then re-block the material feeding from the storage bin 1 to the loading bin 2. In order to speed up the efficiency, the feeding stopper 4 can also be reopened to refill the materials after the materials to be installed in the loading bin 2 are taken out and installed, and the material removal stopper 3 is re-closed. This can achieve rapid refilling of the loading bin 2 and facilitate the rapid operation of the entire anti-leakage and mis-installation device.

[0053] Furthermore, the loading bin 2 is provided with a material taking detection component for detecting the taking of the material to be installed in the loading bin 2. The material taking detection component can be a photoelectric switch located on the loading bin 2; multiple photoelectric switches can be provided, corresponding one to one with the material to be installed in the loading bin 2. Therefore, if all the areas to be installed are currently installed with material to be installed, and the material taking detection component in the loading bin 2 where the material to be installed is located does not detect the specified material to be installed, then the next assembly step is entered, and double insurance is provided by the installation detection component and the material taking detection component.

[0054] Furthermore, the storage bin 1 is provided with a transparent cover 8 for sealing the materials to be installed in the storage bin 1. Figure 1 、 4 As shown, the transparent cover 8 is made of a transparent acrylic plate, the edge of which is connected to the edge of the storage bin 1 through fasteners. The transparent cover 8 closes the top of the storage bin 1 and allows the operator to observe the internal situation of the storage bin 1 through the transparent cover.

[0055] In other embodiments, the storage bin 1 and loading bin 2 can be provided separately, requiring only a corresponding transport mechanism, such as a transport robot, to be provided between them. However, since the storage bin 1 and loading bin 2 are integrally connected in this embodiment, the materials to be installed can be directly transferred from the storage bin 1 to the loading bin 2 by gravity, resulting in a simpler transport structure and an effectively streamlined structure.

[0056] The above embodiments are only preferred embodiments of this patent and are not intended to limit the scope of protection of this patent. Therefore, any equivalent changes made based on the structure, shape, and principle of this patent should be covered within the scope of protection of this patent.
