Description

Technical Field

[0001] This utility model specifically relates to an automatic feeding device for plastic parts. Background Technology

[0002] As a core functional component of a suitcase, the handle typically consists of a handle body and linkage mechanisms at both ends. The key to these linkage mechanisms lies in the use of pins to connect the handle body to movable plastic parts (as shown in the appendix to this application). Figure 1 (As shown) a hinge is used to ensure smooth opening and closing of the handle. In traditional assembly processes, the mating of plastic parts and pins relies on manual positioning and pressing, resulting in low efficiency. With the rapid increase in luggage production capacity, market demand has placed higher requirements on the precision and efficiency of luggage handle assembly, necessitating the development of fully automated assembly equipment to replace manual operation.

[0003] However, the irregular shape of the plastic parts makes "automated feeding" a problem that needs to be solved for automatic luggage handle assembly equipment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automatic feeding device for plastic parts, which addresses the shortcomings of the prior art and realizes automatic sorting, transportation, clamping and positioning of plastic parts.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic feeding device for plastic parts, comprising a frame, characterized in that: the frame is provided with a sorting component for automatically sorting plastic parts, a clamp for clamping and positioning plastic parts, and the frame is also equipped with a transfer component for transferring plastic parts from the sorting component to the clamp.

[0006] By adopting the above technical solution, the sorting component set on the frame can automatically sort the plastic parts, and the transfer component can automatically transfer the sorted plastic parts from the sorting component to the fixture. The whole process does not require manual intervention, which greatly improves the feeding efficiency of plastic parts.

[0007] The aforementioned automatic plastic feeding device can be further configured as follows: the sorting component includes a linear vibrating feeder and a feeding base plate fixed above the linear vibrating feeder. Two sets of symmetrically arranged first sorting plates are fixed on the feeding base plate. A first feeding channel that is gap-fitted with the plastic part is provided between the two sets of first sorting plates. A first stop is provided above the first feeding channel.

[0008] Using the above technical solution, two sets of symmetrically arranged first sorting plates form the first feeding channel, and together with a direct vibrating feeder, fully automatic feeding is achieved, while automatic sorting is also performed to ensure seamless connection throughout the entire process, thus improving overall efficiency. The first stop component above the first feeding channel limits the plastic parts, preventing them from moving up and down within the first feeding channel.

[0009] The aforementioned automatic feeding device for plastic parts can be further configured as follows: the first baffle includes a baffle plate laid above the first feeding channel and a connecting plate integrally bent with the baffle plate; the lower side of the connecting plate is provided with a plurality of first strip holes; the feeding base plate is provided with a first positioning hole corresponding to each group of first strip holes; the side of the first sorting plate is provided with a plurality of second strip holes; the feeding base plate is provided with a second positioning hole corresponding to each group of second strip holes.

[0010] By adopting the above technical solution, the vertical limiting height of the baffle plate on the plastic part can be precisely controlled by adjusting the installation position of the baffle plate on the feeding base plate (utilizing the sliding freedom of the first strip hole), thus adapting to the needs of plastic parts of different thicknesses. The lateral position of the first sorting plate can be flexibly adjusted through the second strip hole to ensure that the width of the first feeding channel is precisely matched with the size of the plastic part, improving adaptability.

[0011] The aforementioned automatic feeding device for plastic parts can be further configured as follows: the transfer component includes a receiving block, the receiving block is distributed at the discharge end of the first feeding channel, and a U-shaped positioning groove is provided above the receiving block, the opening of the U-shaped positioning groove faces the first feeding channel, the end of the baffle plate extends to the top of the U-shaped positioning groove, the receiving block is linked to a reciprocating moving mechanism for driving the receiving block to move laterally along the feeding base plate, and the transfer component also includes a clamping mechanism for transferring the plastic parts from the receiving block to the fixture.

[0012] Using the above technical solution, the U-shaped positioning groove opening faces the first feeding channel and seamlessly connects with the outlet of the first feeding channel, ensuring that the plastic part smoothly slides from the first feeding channel into the receiving block. The baffle plate extends above the U-shaped positioning groove, vertically constraining the plastic part to prevent it from jumping out of the receiving block due to inertia or vibration, and horizontally forming a continuous limiting structure with the first feeding channel's baffle structure, ensuring the stability of the plastic part throughout its journey from the first feeding channel to the receiving block. The reciprocating moving mechanism can quickly switch the receiving block between the clamping mechanism and the first feeding channel, thus facilitating the clamping mechanism to remove the plastic part from the receiving block.

[0013] The aforementioned automatic feeding device for plastic parts can be further configured as follows: the clamping mechanism includes a swing gripper, a first slider linked to the swing gripper, and a first fixed plate. The first slider is slidably engaged with a horizontally placed first slide rail, which is fixedly mounted on the first fixed plate. A first lifting drive cylinder is mounted on the upper end of the first fixed plate, and the output end of the first lifting drive cylinder is linked to the first slider. A second slider is linked to the first fixed plate, and the second slider is slidably engaged with a horizontally placed second slide rail. The second slide rail is fixed on the frame, and a first horizontal drive cylinder is mounted on the frame. The output end of the first horizontal drive cylinder is linked to the first fixed plate.

[0014] Using the above technical solution, the swing gripper is an existing technology that can drive the two grippers at the output end to open and close, and can also drive the two grippers to rotate as a whole. The first lateral drive cylinder controls the first fixed plate to move laterally along the second slide rail, and the lifting cylinder controls the swing gripper to move vertically along the first slide rail until it reaches above the receiving block, aligns with the plastic part, and then removes the plastic part.

[0015] The aforementioned automatic feeding device for plastic parts can be further configured as follows: the oscillating gripper includes a body and two sets of grippers linked to the body. The two sets of grippers can rotate simultaneously relative to the body, and the two sets of grippers can approach or separate from each other. Each set of grippers is linked to a set of support claws. A semi-cylindrical clamping body is provided below the support claws. When the two sets of support claws approach each other, the two sets of semi-cylindrical clamping bodies form a cylindrical clamping body. The outer periphery of the semi-cylindrical clamping body is provided with anti-slip texture.

[0016] Using the above technical solution, since the first connecting hole in the middle of the plastic part is relatively narrow, a support claw is designed. When the two sets of support claws are closed, the two sets of semi-cylindrical clamps form a cylindrical clamp, which facilitates entry into the first connecting hole in the middle of the plastic part. When the two sets of support claws are open, they can grasp the plastic part. The anti-slip texture increases the friction between the support claws and the plastic part, preventing the plastic part from falling out.

[0017] The aforementioned automatic feeding device for plastic parts can be further configured as follows: the reciprocating moving mechanism includes a transmission plate installed below the receiving block, the transmission plate is linked to a first cylinder, the first cylinder drives the receiving block to reciprocate along a direction perpendicular to the first feeding channel through the transmission plate, and a limit plate is fixed at the end of the feeding base plate, the limit plate being parallel to the transmission plate.

[0018] Using the above technical solution, the first cylinder drives the receiving plate to move laterally via the transmission plate until the baffle plate no longer blocks the U-shaped positioning groove. The clamping mechanism can then smoothly remove the plastic part and transfer it to the fixture. When the receiving plate moves laterally, the opening of the U-shaped positioning groove no longer corresponds to the first feeding channel, and the limiting plate blocks the opening to prevent the plastic part from sliding out of the U-shaped positioning groove. Simultaneously, the limiting plate further guides the lateral movement of the receiving plate to prevent it from tilting.

[0019] The aforementioned automatic feeding device for plastic parts can be further configured such that: the fixture includes a positioning seat, and two sets of symmetrically distributed inserts are provided in the middle of the positioning seat.

[0020] Using the above technical solution, two sets of inserts are inserted into the first connecting hole in the middle of the plastic part to achieve clamping and positioning of the plastic part.

Detailed Implementation

[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] like Figures 2 to 6 The automatic feeding device for plastic parts shown includes a frame, on which are mounted a sorting component for automatically sorting plastic parts a, a clamping fixture for clamping and positioning plastic parts a, and a transfer component for transferring plastic parts a from the sorting component to the clamping fixture. The sorting component on the frame automatically sorts the plastic parts a, and the transfer component automatically transfers the sorted plastic parts a from the sorting component to the clamping fixture. The entire process requires no manual intervention, greatly improving the feeding efficiency of plastic parts a.

[0031] The sorting assembly includes a vibrating feeder 1 and a feeding base plate 2 fixed above the vibrating feeder 1. Two sets of symmetrically arranged first sorting plates 3 are fixed on the feeding base plate 2. A first feeding channel 4, which is clearance-fitted to the plastic part a, is provided between the two sets of first sorting plates 3. A first stop is provided above the first feeding channel 4. The two sets of symmetrically arranged first sorting plates 3 constitute the first feeding channel 4, and together with the vibrating feeder 1, achieve fully automatic feeding and automatic sorting, ensuring seamless connection throughout the process and improving overall efficiency. The first stop limits the movement of the plastic part a above the first feeding channel 4, preventing it from moving up and down within the channel.

[0032] The first baffle includes a baffle plate 5 laid above the first feeding channel 4 and a connecting plate 6 integrally bent with the baffle plate 5. The lower side of the connecting plate 6 has several sets of first strip holes 7. The feeding base plate 2 has a first positioning hole corresponding to each set of first strip holes 7, and the first strip holes 7 are connected to the first positioning holes by screws. The side of the first sorting plate 3 has several sets of second strip holes 8. The feeding base plate 2 has a second positioning hole corresponding to each set of second strip holes 8, and the second strip holes 8 are connected to the second positioning holes by screws. By adjusting the installation position of the baffle plate 5 on the feeding base plate 2 (utilizing the sliding freedom of the first strip holes 7), the vertical limiting height of the baffle plate 5 on the plastic part a can be precisely controlled, adapting to the needs of plastic parts a of different thicknesses. The lateral position of the first sorting plate 3 can be flexibly adjusted through the second strip holes 8, ensuring that the width of the first feeding channel 4 precisely matches the size of the plastic part a, improving adaptability.

[0033] The transfer assembly includes a receiving block 9, which is located at the outlet end of the first feeding channel 4. A U-shaped positioning groove 10 is provided above the receiving block 9, with its opening facing the first feeding channel 4. The end of a baffle plate 5 extends above the U-shaped positioning groove 10. The receiving block 9 is linked to a reciprocating mechanism for driving it to move laterally along the feeding base plate 2. The transfer assembly also includes a clamping mechanism for transferring the plastic part a from the receiving block 9 to the fixture. The U-shaped positioning groove 10 opens towards the first feeding channel 4 and seamlessly connects to the outlet of the first feeding channel 4, ensuring that the plastic part a smoothly slides from the first feeding channel 4 into the receiving block 9. The baffle plate 5 extends above the U-shaped positioning groove 10, vertically constraining the plastic part a to prevent it from jumping out of the receiving block 9 due to inertia or vibration. Laterally, it forms a continuous limiting structure with the baffle of the first feeding channel 4, ensuring the stability of the plastic part a throughout its journey from the first feeding channel 4 to the receiving block 9. The reciprocating moving mechanism can drive the receiving block 9 to quickly switch between the clamping mechanism and the first feeding channel 4, thereby facilitating the clamping mechanism to remove the plastic part a from the receiving block 9.

[0034] The clamping mechanism includes a swing gripper 11, a first slider 12 linked to the swing gripper 11, and a first fixed plate 13. The first slider 12 is slidably fitted with a horizontally placed first slide rail 14, which is fixedly mounted on the first fixed plate 13. A first lifting drive cylinder 15 is mounted on the upper end of the first fixed plate 13, and its output end is linked to the first slider 12. A second slider 16 is linked to the first fixed plate 13, and its second slider 16 is slidably fitted with a horizontally placed second slide rail 17, which is fixed to the frame. A first horizontal drive cylinder 18 is mounted on the frame, and its output end is linked to the first fixed plate 13. The swing gripper 11 is existing technology, capable of driving the two grippers at its output end to open and close, and also capable of driving the two grippers as a whole to rotate. The first lateral drive cylinder 18 controls the first fixed plate 13 to move laterally along the second slide rail 17, and the lifting cylinder controls the swing gripper 11 to move vertically along the first slide rail 14 until it reaches above the receiving block 9, aligns with the plastic part a, and then takes out the plastic part a.

[0035] The oscillating pneumatic gripper 11 includes a main body and two sets of pneumatic grippers linked to the main body. The two sets of pneumatic grippers can rotate simultaneously relative to the main body, and can approach or separate from each other. Each set of pneumatic grippers is linked to a set of support claws 19. A semi-cylindrical clamping body 20 is located below the support claws 19. When the two sets of support claws 19 approach each other, the two sets of semi-cylindrical clamping bodies 20 form a cylindrical clamping body. The outer periphery of the semi-cylindrical clamping body 20 is provided with anti-slip texture. Due to the first connecting hole a1 in the middle of the plastic part a (e.g., Figure 1 The plastic part a (as shown) is relatively narrow, so support claws 19 are designed. When the two sets of support claws 19 are closed, the two sets of semi-cylindrical clamps 20 form a cylindrical clamp, which facilitates entry into the first connecting hole a1 in the middle of the plastic part a. When the two sets of support claws 19 are open, the plastic part a can be gripped. The anti-slip texture increases the friction between the support claws 19 and the plastic part a, preventing the plastic part a from falling out.

[0036] The reciprocating movement mechanism includes a transmission plate 21 installed below the receiving block 9. The transmission plate 21 is linked to a first cylinder 22. The first cylinder 22 drives the receiving block 9 to reciprocate in a direction perpendicular to the first feeding channel 4 via the transmission plate 21. A limit plate 23 is fixed to the end of the feeding base plate 2, and the limit plate 23 is parallel to the transmission plate 21. The first cylinder 22 drives the receiving plate to move laterally via the transmission plate 21 until the baffle plate 5 no longer blocks the U-shaped positioning groove 10. The clamping mechanism can then smoothly remove the plastic part a and transfer it to the fixture. When the receiving plate moves laterally, the opening of the U-shaped positioning groove 10 no longer corresponds to the first feeding channel 4, and the limit plate 23 blocks the opening to prevent the plastic part a from sliding out of the U-shaped positioning groove 10. At the same time, the limit plate 23 further guides the lateral movement of the receiving plate to prevent the receiving plate from tilting.

[0037] The fixture includes a positioning base 24, with two sets of symmetrically distributed insertion pins 25 arranged in the middle of the positioning base 24. The two sets of insertion pins 25 are inserted into the first connecting hole a1 in the middle of the plastic part a to achieve clamping and positioning of the plastic part a.

[0038] The working principle of this embodiment is as follows: Plastic parts a are transported in an orderly manner into the first feeding channel 4 in conjunction with a vibrating feeding plate. Plastic parts a are naturally sorted within the first feeding channel 4 and transported forward in an orderly fashion. When the plastic parts move into the U-shaped positioning groove 10 of the receiving block 9, the receiving block 9 moves laterally until the baffle plate 5 no longer blocks the U-shaped positioning groove 10. The swinging gripper 11 then moves downwards until the two sets of support claws 19 insert into the first connecting hole a1 in the middle of the plastic part a. The two sets of support claws 19 then open, achieving reverse clamping of the plastic part a. The swinging gripper 11 then moves the plastic part a from the receiving block 9 onto the clamp. In actual use, the swinging gripper 11 rotates the plastic part a to a suitable angle according to the placement direction of the clamp. The entire process requires no manual intervention, greatly improving the feeding efficiency of the plastic part a.
