Description

Technical Field

[0001] The present invention relates to the technical field of speaker manufacturing, and particularly to an automatic grasping device for speaker production. Background Art

[0002] A speaker is a sound generating device that can convert an electrical signal into a sound signal; a speaker cone is one of the important components of a speaker and plays a key role in the sound generation of the speaker. It is also called a diaphragm or a sound film, and its material is paper, plastic, etc.; currently, in the speaker assembly line, the feeding of the speaker cone is mainly achieved manually, and the assembly efficiency is relatively low; in addition, the speaker cones are usually stacked together in a nested manner. When feeding, the nested speaker cones need to be separated one by one, and the speaker cones are usually relatively thin and light, which greatly increases the operation difficulty and requires a high level of proficiency for the operator. A solution to the above technical problems needs to be proposed;

[0003] For example, in the patent document with the publication number CN211920130U, the device is provided with a feeding device. When the number of speaker cones taken out from the storage unit of the picking manipulator is more than one, that is, when the number of speaker cones on at least one receiving tray is more than one, the receiving tray has negative pressure to adsorb and fix the lower-layer speaker cone, and the feeding component can only take away the upper-layer speaker cone on the receiving tray, so as to achieve the separation of multiple speaker cones; this feeding device can realize the feeding of the speaker cones one by one, avoid the situation of multiple speaker cones being nested during feeding, improve the working efficiency and the assembly efficiency of the speaker, and reduce the labor cost;

[0004] However, when the above device is used, if the number of speaker cones taken out from the storage unit is more than two, the negative pressure of the receiving tray only adsorbs and fixes the lower-layer speaker cone. Due to the friction between the speaker cones, the feeding component will take away two speaker cones on the receiving tray and cannot accurately take away only one speaker cone, which is likely to affect the assembly efficiency of the speaker; moreover, after the receiving tray adsorbs the lower-layer speaker cone through negative pressure, the speaker cone in the receiving tray will be inconvenient for subsequent processing and needs to be removed manually, increasing the labor intensity of the workers; at the same time, the existing speaker cone feeding method requires the cooperation of the receiving tray and the feeding component, and the structure is relatively complex, making the device prone to failure and difficult to repair. Summary of the Invention

[0005] The technical problems solved by this solution are as follows:

[0006] (1) How to set up a separating mechanism to block the speaker diaphragms that are nested above the lowermost speaker diaphragm by two partition plates. During the process of the extending end of the cylinder extending to the longest state, the two pushing plates are separated from the lowermost speaker diaphragm, and the U-shaped plate provides a pressing thrust to the lowermost speaker diaphragm, causing it to fall without separating two or more speaker diaphragms, which improves the working efficiency and the assembly efficiency of the speakers.

[0007] (2) How to set up a blocking mechanism to block the lowermost speaker diaphragm by two pushing plates to prevent it from falling onto the workbench. During the process of the cylinder resetting, the two pushing plates first reset to their original positions, and then the two partition plates reset to their original positions, so that the nested speaker diaphragms will fall onto the two pushing plates, facilitating the continuous separation work of the speaker diaphragms and avoiding the process of manual assistance for separating the speaker diaphragms.

[0008] (3) How to set up a grasping mechanism. When the lowermost speaker diaphragm falls into the receiving groove, the speaker diaphragm is adsorbed in the receiving groove through the suction hose to prevent it from falling out of the receiving groove. When the robotic arm controls the moving seat to the second set position, the input end of the suction hose is blocked by the rubber plate, and the speaker diaphragm is not subjected to suction, facilitating manual removal of it from the receiving groove. This feeding structure is simple, convenient for subsequent manual maintenance, and reduces the labor intensity of the workers.

[0009] The object of the present invention can be achieved by the following technical solutions: An automatic grasping device for speaker production, including a workbench. On both sides of the top of the workbench, a first base and a second base are respectively fixedly installed. A blocking mechanism for preventing the speaker diaphragm from falling is movably arranged on the first base. A separating mechanism for separating the nested speaker diaphragms is movably arranged on the second base. A robotic arm for conveying the speaker diaphragm is rotatably arranged on the workbench in front of the second base. The robotic arm is a prior art, and a grasping mechanism for grasping the speaker diaphragm is arranged at one end of the robotic arm.

[0010] The separating mechanism includes a second slider slidably connected to the second base through a second track. A baffle is fixedly installed on the top of the second slider. A transmission rod is fixedly connected to the side of the baffle facing the guide tube. A cylinder for driving the second slider to move is also fixedly installed on the second base. Two partition plates for separating two speaker diaphragms are fixedly installed at one end of the second slider away from the cylinder. A separating unit for assisting in separating the two speaker diaphragms is arranged below the two partition plates.

[0011] A further technical improvement of the present invention lies in that: A guide sleeve for limiting the transmission rod is fixedly installed on the guide tube, and a second inclined block is fixedly connected to the guide tube on one side of the guide sleeve.

[0012] A further technical improvement of the present invention lies in that: the separating unit includes a U-shaped plate. Two limiting rods are fixedly connected to the top of the U-shaped plate close to the second slider. The top ends of the two limiting rods respectively pass through the corresponding partition plates movably, and a first inclined block is fixedly connected to the top ends of the two limiting rods together. The position of the first inclined block corresponds to the position of the second inclined block. Both partition plates are elastically connected to the first inclined block through first thrust springs; when the air cylinder is started, when the extending end of the air cylinder extends to the first set position, at this time, the two partition plates block the speaker diaphragms that are nested above the lowermost speaker diaphragm, and at the same time, the support base provides support for the two partition plates to prevent the two partition plates from bending, and the transmission rod contacts the push plate. During the process that the extending end of the air cylinder extends to the longest state, the transmission rod provides a thrust to the push plate, causing the first slider to slide and drive the two pushing plates to separate from the lowermost speaker diaphragm. At the same time, through the relative sliding of the first inclined block and the second inclined block, the U-shaped plate provides a pressing thrust to the lowermost speaker diaphragm, causing it to fall. Only one speaker diaphragm can be separated in each of the above processes, and two or more speaker diaphragms will not be separated, which improves the working efficiency and the assembly efficiency of the speaker.

[0013] A further technical improvement of the present invention lies in that: the blocking mechanism includes a first slider slidably connected to the first base through a first track. A push plate is fixedly installed on the top of the first slider. The position of the push plate corresponds to the position of the transmission rod. A fixed seat is also fixedly installed on the first base. A guide rod is fixedly installed on the side of the fixed seat facing the push plate. One end of the guide rod passes through the push plate movably. A second thrust spring is arranged between the push plate and the fixed seat. Two pushing plates for blocking the falling of the speaker diaphragm are fixedly installed at one end of the first slider away from the fixed seat; the nested speaker diaphragms are placed in the guide tube. At this time, the extending end of the air cylinder is in the shortest state. The two pushing plates provide a block for the lowermost speaker diaphragm to prevent it from falling onto the workbench. When the air cylinder resets, the two pushing plates first reset to their original positions, and then the two partition plates reset to their original positions, so that the nested speaker diaphragms will fall onto the two pushing plates, facilitating the continuous separation work of the speaker diaphragms and avoiding the process of manual assistance for separating the speaker diaphragms.

[0014] A further technical improvement of the present invention lies in that: a support base for receiving the two partition plates is further arranged on the first slider.

[0015] A further technical improvement of the present invention lies in that: the grasping mechanism includes a moving seat fixedly connected to one end of the robotic arm. A receiving groove for receiving the speaker diaphragm is formed at the top of the moving seat. An air suction groove is further formed at the bottom of the receiving groove. The air suction groove communicates with the back surface of the moving seat. An air suction hose is embedded at the bottom of the air suction groove. The output end of the air suction hose is communicated with the input end of an external vacuum pump. Before the cylinder is opened, the moving seat is controlled by the robotic arm to the receiving station below the guiding tube. When the lowermost speaker diaphragm falls into the receiving groove, by turning on the vacuum pump, the input end of the air suction hose extracts the air in the air suction groove, so that the speaker diaphragm is adsorbed in the receiving groove to prevent it from falling out of the receiving groove. When the robotic arm controls the moving seat to the second set position, at this time, the rubber plate extends into the air suction groove to block the space between the input end of the air suction hose and the speaker diaphragm, so that the input end of the air suction hose only sucks air to the outside through the air suction groove, while the speaker diaphragm is not subjected to suction force, which is convenient for manual removal from the receiving groove. This feeding structure is simple, convenient for subsequent manual maintenance, and reduces the labor intensity of workers.

[0016] A further technical improvement of the present invention lies in that: a second mounting plate is fixedly installed on the workbench. A rubber plate is fixedly installed on the front surface of the second mounting plate. The position of the rubber plate corresponds to the position of the air suction groove.

[0017] A further technical improvement of the present invention lies in that: the thickness of the rubber plate is less than the depth of the air suction groove.

[0018] A further technical improvement of the present invention lies in that: a longitudinally arranged first mounting plate is fixedly connected to the top of the workbench. A guiding tube for guiding the speaker diaphragm is fixedly installed on the front surface of the first mounting plate. Openings are formed on both the front and rear sides at the bottom of the guiding tube.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] When the present invention is in use, when the extending end of the cylinder extends to the first set position, at this time, the two partition plates block the speaker diaphragms nested above the lowermost speaker diaphragm. At the same time, the support seat provides support for the two partition plates to prevent the two partition plates from bending. The transmission rod contacts the push plate. During the process of the extending end of the cylinder extending to the longest state, the transmission rod provides a thrust to the push plate, so that the first slider slides to drive the two pushing plates to disengage from the lowermost speaker diaphragm. At the same time, through the relative sliding of the first inclined block and the second inclined block, the U-shaped plate provides a pressing thrust to the lowermost speaker diaphragm to make it fall. The above process can only separate one speaker diaphragm each time, and will not separate two or more speaker diaphragms, which improves the working efficiency and the assembly efficiency of the speaker.

[0021] When the present invention is in use, the stacked speaker diaphragms are placed into the guiding tube. At this time, the extending end of the air cylinder is in the shortest state. Two pushing plates provide a block for the lowermost speaker diaphragm to prevent it from falling onto the workbench. When the air cylinder resets, the two pushing plates first reset to their original positions, and then the two partition plates reset to their original positions, causing the stacked speaker diaphragms to fall onto the two pushing plates, facilitating the continuous separation of the speaker diaphragms and avoiding the process of manual assistance for separating the speaker diaphragms.

[0022] When the present invention is in use, the robotic arm is used to control the moving seat to the receiving station below the guiding tube. When the lowermost speaker diaphragm falls into the receiving groove, the vacuum pump is turned on, causing the input end of the suction hose to extract the air in the suction groove, so that the speaker diaphragm is adsorbed in the receiving groove to prevent it from falling out of the receiving groove. When the robotic arm controls the moving seat to the second set position, at this time, the rubber plate extends into the suction groove to block between the input end of the suction hose and the speaker diaphragm, causing the input end of the suction hose to only suck air to the outside through the suction groove, while the speaker diaphragm is not subject to suction, facilitating manual removal of it from the receiving groove. This feeding structure is simple, convenient for subsequent manual maintenance, and reduces the labor intensity of the workers. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Please refer to Figures 3 - 5 As shown, the above-mentioned separating unit 307 includes a U-shaped plate 3074. Two limiting rods 3073 are fixedly connected to the top of the U-shaped plate 3074 close to the second slider 306. The top ends of the two limiting rods 3073 respectively pass through the corresponding partition plates 308 movably, and the top ends of the two limiting rods 3073 are fixedly connected together with a first inclined block 3071. The position of the first inclined block 3071 corresponds to the position of the second inclined block 303. Both partition plates 308 are elastically connected to the first inclined block 3071 through first thrust springs 3072; when the air cylinder 305 is opened, when the extending end of the air cylinder 305 extends to the first set position, at this time, the two partition plates 308 block the speaker diaphragms that are nested above the lowermost speaker diaphragm, and at the same time, support is provided for the two partition plates 308 through the support seat 902 to prevent the two partition plates 308 from being bent, and the transmission rod 302 comes into contact with the push plate 907. When the extending end of the air cylinder 305 extends to the longest state, the transmission rod 302 provides a thrust to the push plate 907, causing the first slider 903 to slide and drive the two pushing plates 901 to disengage from the lowermost speaker diaphragm. At the same time, relative sliding occurs between the first inclined block 3071 and the second inclined block 303, so that the U-shaped plate 3074 provides a pressing thrust to the lowermost speaker diaphragm, causing it to fall. Only one speaker diaphragm can be separated in each of the above processes, and two or more speaker diaphragms will not be separated, which improves the working efficiency and the assembly efficiency of the speaker.

[0037] Please refer to Figure 1 and Figure 2As shown in the figure, the above-mentioned blocking mechanism 9 includes a first slider 903 slidably connected to a first base 8 through a first track. A push plate 907 is fixedly installed at the top of the first slider 903. The position of the push plate 907 corresponds to the position of the transmission rod 302.

Two push plates 901 for blocking the speaker diaphragm from falling are fixedly installed at one end of the first slider 903 away from the fixed seat 904. The two push plates 901 are respectively located in the two openings 2. The nested speaker diaphragms are placed into the guide tube 1. At this time, the extending end of the air cylinder 305 is in the shortest state. The two push plates 901 provide blocking for the lowermost speaker diaphragm to prevent it from falling onto the workbench 7. When the air cylinder 305 resets, the two push plates 901 first reset to their original positions, and then the two partition plates 308 reset to their original positions, so that the nested speaker diaphragms will fall onto the two push plates 901, facilitating the continuous separation work of the speaker diaphragms and avoiding the process of manual assistance for separating the speaker diaphragms.

[0038] Please refer to Figure 2 As shown in the figure, a support seat 902 for receiving the two partition plates 308 is also provided on the above-mentioned first slider 903.

[0039] Please refer to Figure 1 、 Figure 6 and Figure 7As shown, the above-mentioned grasping mechanism 5 includes a moving seat 505 fixedly connected to one end of the robotic arm 6. A storage groove 501 for storing the speaker diaphragm is formed at the top of the moving seat 505. An air suction groove 506 is further formed at the bottom of the storage groove 501. The air suction groove 506 communicates with the back surface of the moving seat 505. A second mounting plate 503 is fixedly installed on the workbench 7. A rubber plate 502 is fixedly installed on the front surface of the second mounting plate 503. The position of the rubber plate 502 corresponds to the position of the air suction groove 506. An air suction hose 504 is embedded at the bottom of the air suction groove 506. The output end of the air suction hose 504 is communicated with the input end of an external vacuum pump; before the air cylinder 305 is opened, the moving seat 505 is controlled by the robotic arm 6 to the receiving station below the guiding tube 1. When the lowermost speaker diaphragm falls into the storage groove 501, by turning on the vacuum pump, the input end of the air suction hose 504 extracts the air in the air suction groove 506, so that the speaker diaphragm is adsorbed in the storage groove 501 to prevent it from falling out of the storage groove 501. When the robotic arm 6 controls the moving seat 505 to the second set position, at this time the rubber plate 502 extends into the air suction groove 506 to block between the input end of the air suction hose 504 and the speaker diaphragm, so that the input end of the air suction hose 504 only sucks air to the outside through the air suction groove 506, and the speaker diaphragm is not subjected to suction force, which is convenient for manual removal from the storage groove 501. This feeding structure is simple, convenient for subsequent manual maintenance, and reduces the labor intensity of workers.

[0040] Please refer to Figure 6 and Figure 7 As shown, the thickness of the above-mentioned rubber plate 502 is less than the depth of the air suction groove 506.

[0041] Working principle: When the present invention is in use, first, the nested speaker diaphragms are placed into the guiding tube 1. At this time, the extending end of the air cylinder 305 is in the shortest state. Two pushing plates 901 provide a block to the lowermost speaker diaphragm to prevent it from falling onto the workbench 7. The air cylinder 305 is started. When the extending end of the air cylinder 305 extends to the first set position, at this time, two partition plates 308 block the speaker diaphragms nested above the lowermost speaker diaphragm. At the same time, the support base 902 provides support to the two partition plates 308 to prevent the two partition plates 308 from bending. The transmission rod 302 comes into contact with the push plate 907. During the process of the extending end of the air cylinder 305 extending to the longest state, the transmission rod 302 provides a thrust to the push plate 907, causing the first slider 903 to slide and drive the two pushing plates 901 to disengage from the lowermost speaker diaphragm. At the same time, through the relative sliding of the first inclined block 3071 and the second inclined block 303, the U-shaped plate 3074 provides a pressing thrust to the lowermost speaker diaphragm, causing it to fall. When the air cylinder 305 resets, the two pushing plates 901 first reset to their original positions, and then the two partition plates 308 reset to their original positions, causing the nested speaker diaphragms to fall onto the two pushing plates 901, facilitating the continuous separation work of the speaker diaphragms, avoiding the process of manual assistance in separating the speaker diaphragms. At the same time, only one speaker diaphragm can be separated each time in the above process, and two or more speaker diaphragms will not be separated, which improves the work efficiency and the assembly efficiency of the speaker; before starting the air cylinder 305, the robotic arm 6 controls the moving seat 505 to the receiving station below the guiding tube 1. When the lowermost speaker diaphragm falls into the receiving groove 501, by starting the vacuum pump, the input end of the suction hose 504 extracts the air in the suction groove 506, causing the speaker diaphragm to be adsorbed in the receiving groove 501 to prevent it from falling out of the receiving groove 501. When the robotic arm 6 controls the moving seat 505 to the second set position, at this time, the rubber plate 502 extends into the suction groove 506 to block between the input end of the suction hose 504 and the speaker diaphragm, causing the input end of the suction hose 504 to only suck air from the outside through the suction groove 506, and the speaker diaphragm is not subjected to suction force, facilitating manual removal of it from the receiving groove 501. This feeding structure is simple, convenient for subsequent manual maintenance, and reduces the labor intensity of the workers.
