Technical Field

[0001] The present application relates to the technical field of bulb manufacturing equipment, and particularly relates to a material blocking mechanism and a bulb shell loading device. Background Art

[0002] During the manufacturing process of bulbs, it is necessary to convey the bulb shells through a conveying pipeline, and then use a manipulator to grab the bulb shells output from the conveying pipeline onto the production line. In the related art, in order to enable the bulb shells to output from the conveying pipeline in an orderly manner, at least two sets of material blocking mechanisms need to be set. The two sets of material blocking mechanisms are distributed along the conveying direction of the conveying pipeline. Each set of material blocking mechanism includes a cylinder and a material blocking block. The cylinder drives the material blocking block to enter or exit the conveying pipeline to allow or restrict the bulb shells in the conveying pipeline to pass through. By releasing the bulb shells in sequence through the two sets of material blocking mechanisms, the bulb shells can be output from the conveying pipeline in an orderly manner. However, at least two sets of material blocking mechanisms and at least two cylinders are required, resulting in a relatively high production equipment cost. Summary of the Utility Model

Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0039] Referring to Figures 1 to 3 , according to an embodiment of the first aspect of the present application, the material blocking mechanism 1000 includes: a connecting frame 100, a connecting seat 200, a material blocking portion 300, a first guiding portion 400, a second guiding portion 500, a clamping portion 600, a second elastic portion 700, and a material blocking driving portion 800.

[0040] The connecting frame 100 can be used to be arranged on the ground to support the material blocking mechanism 1000 of the present application, or fixedly connected to other machine frames to fix the material blocking mechanism 1000 of the present application.

[0041] The connecting seat 200 can be driven by the material blocking driving portion 800 to move relative to the connecting frame 100. In this embodiment, the connecting seat 200 is slidably connected to the connecting frame 100 through the material blocking portion 300. In some other embodiments, the connecting seat 200 can also be directly slidably connected to the connecting frame 100.

[0042] The material blocking portion 300 is arranged on the connecting seat 200 and is slidably matched with the connecting frame 100, so that the material blocking portion 300 can approach or move away from the conveying channel 2000.

[0043] A plurality of first guiding portions 400 are provided, and the plurality of first guiding portions 400 are all fixedly connected to the connecting seat 200.

[0044] A plurality of second guiding portions 500 are provided and are in one-to-one correspondence with the first guiding portions 400. The second guiding portions 500 are slidably matched with the connecting frame 100, so that the plurality of second guiding portions 500 can approach or move away from each other; and the second guiding portions 500 are slidably matched with the first guiding portions 400, so that the first guiding portions can push the second guiding portions 500 to move away from each other.

[0045] A plurality of clamping portions 600 are provided and are in one-to-one correspondence with the second guiding portions 500. The clamping portions 600 are fixedly connected to the second guiding portions 500, and the clamping portions 600 surround the outlet 2100 of the conveying channel 2000.

[0046] The second elastic portion 700 is connected to the clamping portions 600 and is used to give an elastic force for the plurality of clamping portions 600 to approach each other.

[0047] The material blocking driving part 800 is drivingly connected to the connecting seat 200 for driving the connecting seat 200 to move between a first position and a second position.

[0048] Wherein, when the connecting seat 200 moves from the first position to the second position, the material blocking part 300 approaches the conveying channel 2000 to abut against the blister shell in the conveying channel 2000, and the first guiding part 400 is in sliding fit with the second guiding part 500, so that the plurality of clamping parts 600 move away from each other to allow the blister shell to pass through; when the connecting seat 200 moves from the second position to the first position, the material blocking part 300 moves away from the conveying channel 2000 to release the blister shell in the conveying channel 2000, the first guiding part 400 moves away from the second guiding part 500, and the plurality of clamping parts 600 move closer to each other to restrict the blister shell from passing through.

[0049] One operation process of the material blocking mechanism 1000 of the present application is as follows:

[0050] There are multiple bulb shells arranged along the conveying direction of the conveying channel 2000 inside the conveying channel 2000, and the bulb shells can move along the conveying direction of the conveying channel 2000. In the initial state, the conveying channel 2000 has output a bulb shell that has passed through the material blocking part 300 and the clamping part 600 and landed on the fixture, waiting for the manipulator to pick it up. And the connecting seat 200 is located at the first position. At this time, the material blocking part 300 is far away from the conveying channel 2000, and the material blocking part 300 does not abut against the bulb shell inside the conveying channel 2000 to allow the bulb shell to pass through. And the first guiding part 400 is far away from the second guiding part 500. Under the action of the second elastic part 700, the multiple clamping parts 600 approach each other. The second guiding part 500 blocks the outlet 2100 of the conveying channel 2000 to prevent the first bulb shell at the front end inside the conveying channel 2000 from passing between the multiple second guiding parts 500, thereby preventing the conveying channel 2000 from continuously outputting bulb shells. After the manipulator picks up the bulb shell to be picked up, the material blocking driving part drives the connecting seat 200 to move from the first position to the second position. It should be understood that the material blocking part 300 is located at a position close to the outlet 2100 of the conveying channel 2000. When the connecting seat 200 moves from the first position to the second position, the material blocking part 300 approaches the conveying channel 2000 and can abut against the second bulb shell at the front end inside the conveying channel 2000 to limit the continuous conveying of the subsequent bulb shells. And the first guiding part 400 will move towards the second guiding part 500. The first guiding part 400 and the second guiding part 500 are slidably matched to push the multiple second guiding parts 500 away from each other, thereby driving the clamping parts 600 on the second guiding part 500 to move away from each other, so as to remove the blockage of the outlet 2100 of the conveying channel 2000, allowing the first bulb shell at the front end inside the conveying channel 2000 to pass between the multiple second guiding parts 500 and fall onto the fixture, waiting for the manipulator to pick it up. The material blocking driving part 800 drives the connecting seat 200 to move from the second position to the first position. The first guiding part 400 moves away from the second guiding part 500 to relieve the thrust on the second guiding part 500. Under the elastic force of the second elastic part 700, the multiple clamping parts 600 approach each other so that the multiple clamping parts 600 approach each other and re-block the outlet 2100 of the conveying channel 2000. And the material blocking part 300 also moves away from the conveying channel 2000 to release the second bulb shell mentioned above inside the conveying channel 2000, allowing the second bulb shell to pass through the material blocking part 300 and be blocked and restricted from output by the clamping part 600. It should be understood that at this time, the second bulb shell at the front end will become the first bulb shell at the front end inside the conveying channel 2000. Repeating this way, the bulb shells can pass through the material blocking part 300 and the clamping part 600 in an orderly manner, and thus be output from the conveying channel 2000 in an orderly manner.

[0051] In summary, when the driving material blocking part 300 drives the connecting seat 200 to move from the first position to the second position, the connecting seat 200 drives the material blocking part 300 to approach the conveying channel 2000 and abut against the blister shell in the conveying channel 2000 to limit the conveyance of the blister shell. At the same time, the connecting seat 200 drives the first guiding part 400 to approach the second guiding part 500. The first guiding part 400 is in sliding fit with the second guiding part 500, and the plurality of second guiding parts 500 move away from each other to drive the plurality of clamping parts 600 to move away from each other to allow the blister shell to pass through. When the driving material blocking part 300 drives the connecting seat 200 to move from the second position to the first position, the connecting seat 200 drives the material blocking part 300 to move away from the conveying channel 2000 and release the blister shell in the conveying channel 2000 to allow the blister shell to pass through. At the same time, the connecting seat 200 drives the first guiding part 400 to move away from the second guiding part 500 to relieve the thrust on the second guiding part 500. The plurality of clamping parts 600 approach each other under the elastic force of the second elastic part 700 to block the outlet 2100 of the conveying channel 2000 and limit the output of the blister shell from the conveying channel 2000. Thus, the material blocking mechanism 1000 of the present application can enable the material blocking part 300 and the clamping part 600 to alternately allow the blister shell to pass through and alternately limit the blister shell from passing through through the material blocking driving part 800, so that the blister shell can be output orderly, and only one material blocking driving part 800 is needed to drive the connecting seat 200 to drive the material blocking part 300 and the first guiding part 400 at the same time, which can save the use of driving parts to reduce the production cost of the material blocking mechanism 1000 and the blister shell feeding device using the material blocking mechanism 1000. Moreover, only one material blocking driving part 800 is needed, the action is simple, and the operation program is simple.

[0052] Specifically, in this embodiment, the material blocking driving part 800 is a cylinder. In some other embodiments, the material blocking driving part 800 can also be a lead screw module.

[0053] Specifically, in this embodiment, there are two clamping parts 600, and both ends of the second elastic part 700 are respectively connected to one of the clamping parts 600. In other embodiments, there can be three or more clamping parts 600. The second elastic parts 700 correspond to the clamping parts 600 one by one. One end of the second elastic part 700 is connected to the side of the clamping part 600 facing away from each other, and the other end is fixedly connected. The second elastic part 700 has a tendency to expand to push the clamping parts 600 so that the plurality of clamping parts 600 have a tendency to approach each other.

[0054] Specifically, the first position and the second position are distributed in the direction away from the conveying channel 2000.

[0055] Refer to Figures 1 to 3, regarding the manner in which the material blocking portion 300 restricts the passage of the blister shell, in this embodiment, one end of the material blocking portion 300 forms a material blocking groove 310, and the groove wall of the material blocking groove 310 is an arc surface. The groove wall of the material blocking groove 310 is used to abut against the outer wall of the blister shell.

[0056] It can be understood that when the material blocking portion 300 approaches the conveying channel 2000 and abuts against the blister shell in the conveying channel 2000, the outer wall of the blister shell will be caught in the material blocking groove 310. The groove wall of the material blocking groove 310 is adapted to the outer wall of the blister shell to improve the restricting effect of the material blocking portion 300. Moreover, the outer wall of the blister shell is an arc surface. By the way of catching the blister shell in the material blocking groove 310, the error tolerance rate of the moving stroke of the material blocking portion 300 is increased. For example, even if the moving stroke of the material blocking portion 300 is a little smaller, the outer wall of the blister shell can still be caught in the material blocking groove 310.

[0057] In some other embodiments, the material blocking portion 300 can also be plate-shaped. When the material blocking portion 300 approaches the conveying channel 2000 and abuts against the blister shell in the conveying channel 2000, the material blocking portion 300 is inserted between two adjacent blister shells and abuts against the end portion of the blister shell.

[0058] Refer to Figures 1 to 3 , regarding the manner in which the clamping portion 600 restricts the passage of the blister shell, in this embodiment, a limiting space 610 is formed between the clamping portions 600. When the connecting seat 200 moves from the first position to the second position, the limiting space 610 becomes larger to allow the blister shell to pass through; when the connecting seat 200 moves from the second position to the first position, the limiting space 610 becomes smaller. The limiting space 610 is used to accommodate a part of the blister shell and restrict the passage of the blister shell.

[0059] It can be understood that when the connecting seat 200 is in the first position, the clamping portions 600 approach and closely adhere to each other under the elastic force of the second elastic portion 700. A concave portion 620 is formed on the side where the clamping portions 600 approach each other. When the clamping portions 600 approach each other, the concave portions 620 of the plurality of clamping portions 600 can form a certain limiting space 610. It should be understood that the end portion of the bulb has a smaller size, and the bulb portion can be accommodated through the limiting space 610 to limit the circumferential direction of the bulb. Since the clamping portions 600 are arranged corresponding to the outlet 2100 of the conveying channel 2000, at this time, the bulb has been partially or completely output outside the conveying channel 2000. By making the bulb portion enter the limiting space 610, the bulb can be limited, preventing the bulb from falling out through the gap between the clamping portions 600 and the conveying channel 2000. Additionally, the bulb portion has a larger size and cannot pass through the limiting space 610, thereby restricting the bulb from passing between the plurality of clamping portions 600. When the connecting seat 200 moves from the first position to the second position, the first guiding portion 400 pushes the second guiding portion 500, and the plurality of clamping portions 600 move away from each other, causing the limiting space 610 to become larger. When the connecting seat 200 reaches the second position, the limiting space 610 is large enough to pass through the entire bulb, enabling the bulb to pass between the plurality of clamping portions 600.

[0060] In some other embodiments, the clamping portion 600 can also be plate-shaped. When the connecting seat 200 is in the first position, the plate-shaped clamping portions 600 are joined together to block the outlet 2100 of the conveying channel 2000. When the connecting seat 200 is in the second position, the clamping portions 600 move away from each other to conduct the outlet 2100 of the conveying channel 2000 to allow the bulb to be output.

[0061] Referring to Figures 1 to 3 , according to some embodiments of the present application, it further includes a first elastic portion 900. The first elastic portion 900 is connected to the material blocking portion 300 and is used to apply an elastic force to the material blocking portion 300 to approach the conveying channel 2000.

[0062] It can be understood that during the process of the material blocking portion 300 approaching the conveying channel 2000 and abutting against the blister shell, the first elastic portion 900 can play a buffering role, making it difficult for the material blocking portion 300 to damage the blister shell. For example, after the material blocking portion 300 abuts against the blister shell in the conveying channel 2000 and the connecting seat 200 has not reached the second position and needs to continue moving towards the conveying channel 2000, the material blocking portion 300 can convert the driving force of the connecting seat 200 into pressure on the first elastic portion 900, compressing the first elastic portion 900, thereby reducing the pressing force of the material blocking portion 300 on the blister shell and avoiding the material blocking portion 300 from pressing and damaging the blister shell. Moreover, during the process of the first guiding portion 400 moving away from the second guiding portion 500, the first elastic portion 900 gradually unfolds and provides an elastic force to the material blocking portion 300 to keep the material blocking portion 300 in contact with the blister shell, so that the clamping portion 600 can approach before the material blocking portion 300 releases the blister shell, ensuring the limiting effect of the clamping portion 600 and preventing the blister shell from passing through the clamping portion 600 before the clamping portion 600 approaches due to the material blocking portion 300 releasing the blister shell too quickly, which affects the orderly conveying of the blister shell.

[0063] Specifically, one end of the first elastic portion 900 is connected to the material blocking portion 300, and the other end is connected to the outer wall of the conveying channel 2000 or the connecting frame 100.

[0064] Referring to Figures 1 to 3 , regarding the guiding form of the second guiding portion 500, the second guiding portion 500 is provided with a guiding inclined surface 510, and the first guiding portion 400 is in sliding fit with the guiding inclined surface 510 to push the second guiding portion 500.

[0065] It can be understood that during the process of the connecting seat 200 moving from the first position to the second position, the first guiding portion 400 will gradually approach the second guiding portion 500 and contact the guiding inclined surface 510 of the second guiding portion 500, and the first guiding portion 400 will slide along the guiding inclined surface 510 of the second guiding portion 500 to push the second guiding portion 500. When the connecting seat 200 moves from the second position to the first position, the first guiding portion 400 slides along the guiding inclined surface 510, and the second guiding portions 500 gradually approach each other under the elastic force of the second elastic member, and the first guiding portion 400 will finally slide away from the guiding inclined surface 510.

[0066] Referring to Figures 1 to 3 , regarding the guiding form of the first guiding portion 400, the first guiding portion 400 is rotatably arranged on the connecting seat 200 to rotate when the first guiding portion 400 is in sliding fit with the second guiding portion 500.

[0067] It can be understood that when the first guiding portion 400 is in sliding fit with the second guiding portion 500, the first guiding portion 400 can rotate to make the sliding fit between the first guiding portion 400 and the second guiding portion 500 smooth.

[0068] Specifically, the first guiding portion 400 includes a bearing. The outer ring of the bearing can be slidably engaged with the guiding inclined surface 510 of the second guiding portion 500. When the bearing slides along the guiding inclined surface 510, the outer ring of the bearing can rotate self - sufficiently.

[0069] In some other embodiments, the first guiding portion 400 may also be provided with an inclined surface that is slidably engaged with the guiding inclined surface 510 of the second guiding portion 500.

[0070] Referring to Figures 1 to 3 , according to some embodiments of the present application, a first slide rail 110 is provided on the connecting frame 100, and a first slider 320 is provided on the material blocking portion 300. The first slider 320 is slidably engaged with the first slide rail 110.

[0071] It can be understood that the moving direction of the material blocking portion 300 is restricted by the sliding engagement between the first slider 320 and the first slide rail 110, and the sliding stability of the material blocking portion 300 is improved.

[0072] Referring to Figures 1 to 3 , according to some embodiments of the present application, a second slide rail 120 is provided on the connecting frame 100, and a second slider 520 is provided on the second guiding portion 500. The second slider 520 is slidably engaged with the second slide rail 120.
