Description

Technical Field

[0001] This invention relates to the field of plastic parts assembly technology, and in particular to an assembly device for plastic parts with bending portions. Background Technology

[0002] Plastic parts can be used in many fields, such as furniture, fitness equipment, medical devices, automobiles, electronics, 3D printing, and children's toy parts.

[0003] As for plastic parts as toy parts, they can be assembled from several parts such as the bottom shell, rubber plug, joints and top cover. However, existing plastic parts are mainly assembled manually by people. Moreover, the structure of each plastic part is complex and the assembly is difficult, resulting in low assembly efficiency and high production cost.

[0004] For example, the automatic toy assembly equipment provided by Chinese patent CN 216029258 U increases the assembly efficiency of toys and reduces production costs through automated processing. However, because the automatic toy assembly equipment is a modular assembly, if any assembly step fails, the preceding and subsequent steps will be affected, thereby affecting the accuracy and efficiency of production and processing. Summary of the Invention

[0005] In view of this, the present invention addresses the deficiencies of the prior art, and its main objective is to provide a plastic parts assembly equipment with high assembly efficiency.

When the material picking and assembly mechanism picks up the first workpiece, the first storage block is driven to move backward through the first adjustment component, so that the baffle and the connection port are separated, so that the first workpiece in the first workpiece receiving cavity is unrestricted, allowing the material picking and assembly mechanism to pick it up and assemble it with the second workpiece. In this way, the assembly steps for making a complete product are broken down to improve the assembly efficiency and assembly accuracy between different plastic parts.

Detailed Implementation

[0046] Please refer to Figure 1-11 As shown, it illustrates the specific structure of a preferred first embodiment of the present invention, which is an assembly device for plastic parts with bent portions, used for loading and assembling a first workpiece 1 and a second workpiece 2 with movable portions. The first workpiece 1 has an insertion portion 1a at its top, and the second workpiece 2 has an insertion hole 2a at its lower end. The insertion portion 1a is inserted into the insertion hole 2a. The assembly device includes:

[0047] The first workpiece vibratory feeder mechanism 10, the second workpiece vibratory feeder mechanism 20, the first workpiece storage mechanism 30 located at the output end of the first workpiece vibratory feeder mechanism 10, the second workpiece storage mechanism 40 located at the output end of the second workpiece vibratory feeder mechanism 20, and the material picking and assembly mechanism 50 connected between the first workpiece storage mechanism 30 and the second workpiece storage mechanism 40.

[0048] The first workpiece vibratory feeder mechanism 10 includes a first workpiece conveying table 11 and a baffle 12 located on the top of the first workpiece conveying table 11 for clamping the moving part; the first workpiece storage mechanism 30 includes a first storage block 31 and a first adjustment component 32. The first storage block 31 is provided with a first workpiece receiving cavity 311 and a connection port 312 communicating with the first workpiece receiving cavity 311. The output end of the first adjustment component 32 is connected to the first storage block 31, driving the first storage block 31 to translate, so that the connection port 312 is inserted into or separated from the baffle 12.

[0049] The material handling assembly mechanism 50 clamps the vertical first workpiece 1 in the first storage block 31 and the second workpiece 2 in the second workpiece storage mechanism 40 for assembly, so that the insertion part 1a is inserted into the insertion hole 2a. Compared with existing equipment for assembling plastic parts, which uses various parts for unified assembly, but a failure at any part installation node will affect the processing efficiency of the preceding and subsequent steps, this equipment for assembling plastic parts uses the first workpiece vibrating plate mechanism 10 and the second workpiece vibrating plate mechanism 20 to respectively transport the first workpiece 1 and the second workpiece 2 into the first workpiece storage mechanism 30 and the second workpiece storage mechanism 40, and the first workpiece storage mechanism 30 and the second workpiece storage mechanism 40 are adapted to the shape and structure of the first workpiece 1 and the second workpiece 2. For example, the first workpiece 1 transported on the first workpiece conveyor table 11 has two parts, upper and lower, and the two parts are connected by a shaft. When multiple first workpieces 1 are transported by mutual compression, they are prone to bending under compression. Therefore, a baffle 12 is installed on the first workpiece conveyor table 11 to clamp the connection between the upper and lower parts of the first workpiece 1. To limit the bending of the first workpiece 1 during transport; when the first workpiece 1 is transported into the first workpiece receiving cavity 311 opened on the first storage block 31, the baffle 12 extends into the connection port 312, so that the upper and lower parts of the first workpiece 1 are in a vertical state to facilitate the normal operation of subsequent steps. When the material picking and assembly mechanism 50 picks up the first workpiece 1, the first storage block 31 is driven to move backward through the first adjustment component 32, so that the baffle 12 and the connection port 3 are separated, so that the first workpiece 1 in the first workpiece receiving cavity 311 is unrestricted, allowing the material picking and assembly mechanism 50 to pick it up and assemble it with the second workpiece 2. In this way, the assembly steps for making a complete product are broken down to improve the assembly efficiency and assembly accuracy between different plastic parts.

[0050] For example, the first workpiece vibratory feeder mechanism 10 also includes a limiting plate 33 located at the top of the first storage block 31, and the limiting plate 33 is connected to the first adjustment component 32. Driving the limiting plate 33 to translate to the top of the first workpiece receiving cavity 311 restricts the movement of the bent portion of the first workpiece 1 within the first storage block 31. Figure 4 As shown, to further restrict the movement of the first workpiece 1 delivered to the first workpiece receiving cavity 311, the first adjusting component 32 pushes the limiting plate 33 so that the limiting plate 33 overlaps the top of the first workpiece 1, causing the upper part of the first workpiece 1 to bend.

[0051] It should be noted that when there are multiple first workpiece receiving cavities 311, the limiting plate 33 has branches 331 extending toward the first workpiece conveying table 11, and the number of branches 331 is the same as the number of first workpiece receiving cavities 311.

[0052] In one embodiment, the first storage block 31 is provided with an elastic element 313 extending into the first workpiece receiving cavity 311. The elastic element 313 has an arc, and the arc corresponds to the bent portion of the first workpiece 1.

[0053] Specifically, the first adjustment component 32 includes a first drive member 321 corresponding to the first storage block 31 and a second drive member 322 connected to the limiting plate 33; the output shaft of the first drive member 321 is connected to a slide rail assembly 323, and the slider in the slide rail assembly 323 is connected to the first storage block 31. The first drive member 321 and the second drive member 322 are cylinders or electric push cylinders, and the output end of the first drive member 321 is connected to a plate frame, which slides on the slide rail assembly 323, and the first storage block 31 is connected to the plate frame. The plate frame adapts the height of the first storage block 31 to the first workpiece conveying table 11, while the slide rail assembly 323 increases the stability of the plate frame when it slides.

[0054] For example, the second workpiece storage mechanism 40 includes a second storage block 41 and an ejection assembly 42. The second storage block 41 is provided with a second workpiece receiving cavity 411, which is connected to the discharge end of the second workpiece vibrating plate mechanism 20. The output end of the ejection assembly 42 extends into the second workpiece receiving cavity 411. As the ejection assembly 42 moves, the position of the second workpiece 2 within the second workpiece receiving cavity 411 is adjusted. Figure 5 As shown, the depth of the inner cavity of the second workpiece receiving cavity 411 is adjusted by the up and down movement of the output end of the ejector assembly 42. When the output end of the ejector assembly 42 moves upward, it pushes the second workpiece 2 in the second workpiece receiving cavity 411 upward to facilitate the material handling assembly mechanism 50 to clamp it and restrict the second workpiece 2 conveyed on the second workpiece vibrating plate mechanism 20 to prevent it from falling. When the output end of the ejector assembly 42 moves downward, it makes the depth of the second workpiece receiving cavity 411 gradually parallel to the discharge end of the second workpiece vibrating plate mechanism 20, so that the second workpiece 2 can be conveyed into the second workpiece receiving cavity 411.

[0055] Specifically, the ejection assembly 42 includes a support block 421 located at the lower part of the second storage block 41, and a seventh drive member 422 connected to the support block 421 at its output end; the support block 421 has multiple legs 4211 that insert into the second workpiece receiving cavity 411, each leg 4211 having a cut-out 4212 at its top, and one side of the cut-out 4212 having an arc adapted to the second workpiece 2; an air passage 4213 is provided at the center of the top of each leg 4211, and one end of the air passage 4213 extends from the bottom of the support block 421. Figure 5As shown, the seventh driving component 422 is a cylinder or an electric pusher. Under the push of the seventh driving component 422, the bearing block 421 moves up and down. The bearing block 421 corresponds to the second storage block 41. Its upper support leg 4211 is inserted into the second workpiece receiving cavity 411. When the upper part of the bearing block 421 overlaps with the lower part of the second storage block 41, the second workpiece 2 in the second workpiece receiving cavity 411 is pushed out in a large area for the material picking and assembly mechanism 50 to pick up.

[0056] To facilitate the entry of the second workpiece 2 into the second workpiece receiving cavity 411, the width of the second workpiece receiving cavity 411 needs to be greater than that of the second workpiece 2. At this time, the second workpiece 2 may tilt or deviate under the push of external force or its own inertia. In order to avoid this situation affecting the gripping of the material picking assembly mechanism 50, a cutout 4212 is opened on the support leg 4211, and the curvature of one side of the cutout 4212 is used to limit the deviation of the second workpiece 2.

[0057] However, after the second workpiece 2 is pushed out of the second workpiece receiving cavity 411 by the support leg 4211, the second workpiece 2 is prone to tipping over due to the limited depth of the second workpiece receiving cavity 411 and the lack of support, making it impossible for the material picking assembly mechanism 50 to clamp the second workpiece 2. Therefore, an air passage 4213 is provided at the top of the support leg 4211, and an air extraction pipe is added to the lower end of the air passage 4213 to form a negative pressure at the lower end of the air passage 4213 to adsorb the second workpiece 2, so as to facilitate the clamping of the material picking assembly mechanism 50.

[0058] The first workpiece conveying table 11 is provided with multiple conveying channels 111. The first workpiece 1 slides in the conveying channel 111. The baffle 12 is provided on the upper part of the first workpiece conveying table 11 and extends into the conveying channel 111.

[0059] The baffle 12 corresponding to the conveyor 111 has two pieces, which are located on the left and right sides of the conveyor 111 respectively, and there is a gap a between the two baffles 12 to allow the joint of the bent part of the first workpiece 1 to pass through.

[0060] For example, the material handling and assembly mechanism 50 includes a first workpiece handling component 51, a second workpiece handling component 52, a discharge port 53, and an assembly platform 54. The discharge port 53 and the assembly platform 54 are aligned with the first workpiece storage mechanism 30 and the second workpiece storage mechanism 40, and the discharge port 53 and the assembly platform 54 are located on the movement paths of the first workpiece handling component 51 and the second workpiece handling component 52. Figure 2As shown, because the discharge port 53 and the assembly platform 54 are displaced on the moving paths of the first workpiece picking component 51 and the second workpiece picking component 52, when the first workpiece 1 and the second workpiece 2 are assembled, the first workpiece 1 can be first picked up from the first storage block 31 by the first workpiece picking component 51 and placed into the assembly platform 54, and then the second workpiece 2 can be picked up from the second storage block 41 by the second workpiece picking component 52 and inserted into the assembly platform 54, so that the insertion hole 2a of the second workpiece 2 and the insertion part 1a of the first workpiece 1 are inserted and assembled. At this time, the second workpiece picking component 52 does not release the second workpiece 2 and resets it so that the second workpiece 2 is taken out of the first workpiece 1 and placed into the discharge port 53 for collection.

[0061] For example, the assembly platform 54 includes a processing table 541, a second adjustment component 542 and a third adjustment component 543. The processing table 541 has a storage cavity 5411 on its upper part and a insertion cavity 5412 on one side. A through hole 5413 is provided on the side adjacent to the insertion cavity 5412. Both the insertion cavity 5412 and the through hole 5413 are connected to the storage cavity 5411. The second adjustment component 542 and the third adjustment component 543 correspond to the insertion cavity 5412 and the through hole 5413 respectively and are offset from each other.

[0062] The second adjustment component 542 includes a third drive member 5421 and a movable piece 5422. The output end of the third drive member 5421 is connected to the movable piece 5422. The movable piece 5422 is provided with a branch bar 54221, which extends into the insertion cavity 5412 and is located beside the storage cavity 5411.

[0063] The third adjustment assembly 543 includes a push rod 5431 and a spring 5432. The spring 5432 is disposed in the through hole 5413 and sleeved on the push rod 5431. One end of the push rod 5431 extends into the receiving cavity 5411. Figure 7 As shown, the receiving cavity 5411 is used to receive the first workpiece 1 and the second workpiece 2. After the second workpiece 2 is placed into the receiving cavity 5411, a part of it is still outside, namely the clamping part of the second workpiece picking component 52. At this time, since the receiving cavity 5411 needs to have enough space to facilitate the insertion of the first workpiece 1 and the second workpiece 2, and the first workpiece 1 has a bent part, in order to avoid the second workpiece 2 bending when inserted into the receiving cavity 5411, which would cause the connection between the second workpiece 2 and the first workpiece 1 to be unstable, after the first workpiece 1 is inserted into the receiving cavity 5411, the top rod 5431 abuts against the two opposite walls of the second workpiece 1 to restrict the position of the first workpiece 1. Then, the branch strip 54221 on the moving piece 5422 is inserted into the joint of the first workpiece 1 to restrict the bending of the first workpiece 1 under the pressure of the second workpiece 2, thereby improving the stability of the connection between the second workpiece 2 and the first workpiece 1.

[0064] Specifically, the movable piece 5422 is located above the push rod 5431, and the movable piece 5422 is driven by the third drive member 5421, which is a clamp cylinder. When the third drive member 5421 drives the movable piece 5422, the movable piece 5422 moves horizontally within the insertion cavity 5412, that is, it moves left and right. When the movable piece 5422 moves to the left, it inserts into the bending joint of the first workpiece 1. At this time, if the first workpiece 1 wants to bend, it cannot bend because it is in contact with the movable piece 5422. The push rod 5431 uses the elastic force of the spring 5432 to resist the first workpiece 1 and restrict the movement of the first workpiece 1.

[0065] When the first workpiece 1 is inserted into the receiving cavity 5411, it compresses the push rod 5431, causing the push rod 5431 to move outward within the receiving cavity 5411 and deforming the spring 5432. When the push rod 5431 is fully inserted into the receiving cavity 5411, it abuts against the side wall of the first workpiece 1 under the elastic restoring force of the spring 5432, making it difficult for the first workpiece 1 to move easily without external force. This ensures that the bending joint of the first workpiece 1 corresponds to the branch bar 54221. Then, the third driving member 5421 drives the moving piece 5422 to move, so that the branch bar 54221 is inserted into the bending joint of the first workpiece 1 to restrict the bending of the first workpiece 1, thereby facilitating the insertion of the second workpiece 2 and the first workpiece 1.

[0066] For example, both the first workpiece picking assembly 51 and the second workpiece picking assembly 52 include a fourth driving component 01, a connecting frame 02, and a fifth driving component 03. The fourth driving component 01 includes two transmission belts 011, two guide rails 012, and a driving cylinder 013. The two transmission belts 011 are located between the two guide rails 012.

[0067] The connecting frame 02 is equipped with a slider 021 and a clamping plate 022. The slider 021 is slidably connected to the guide rail 012, and the clamping plate 022 is connected to the conveyor belt 011.

[0068] The fifth driving component 03 is mounted on the connecting frame 02, and the output end of the fifth driving component 03 on the first workpiece picking assembly 51 is connected to the first clamp 04. The output end of the fifth driving component 03 on the second workpiece picking assembly 52 is connected to the second clamp 05. Figure 8 As shown, when the first clamp 04 and the second clamp 05 need to pick up the first workpiece 1 and the second workpiece 2 from the first storage block 31 and the second storage block 42 respectively, the rotation of the transmission belt 011 driven by the drive cylinder 013 causes the clamping plate 022 to move along the transmission belt 011. Since the connecting frame 02 is installed on the clamping plate 022, the connecting frame 02 slides on the guide rail 012 through the slider 021, thereby ensuring the stability of the first clamp 04 and the second clamp 05 when moving; the drive cylinder 013 can be a motor.

[0069] The first fixture 04 includes a material handling head 041, which has an air extraction end 0411 and an air pipe connection end 0412. The air extraction end 0411 corresponds to the first workpiece 1.

[0070] The second clamp 05 includes a sixth driving member 051, a first clamping block 052, and a second clamping block 053. The first clamping block 052 and the second clamping block 053 are respectively connected to the output end of the sixth driving member 051. The first clamping block 052 has a first pressing foot 0521, and the second clamping block 053 has a second pressing foot 0531. The first pressing foot 0521 and the second pressing foot 0531 correspond to each other, and the opposing surfaces of the first pressing foot 0521 and the second pressing foot 0531 are respectively provided with a protrusion 0522 and an indentation 0532, and both the protrusion 0522 and the indentation 0532 correspond to the second workpiece 2. Figure 9-10 As shown, when the first clamp 04 picks up the first workpiece, it uses the cooperation of the picking head 041 and the suction pipe. When the suction pipe draws air, the suction end 0411 of the picking head 041 generates negative pressure and sucks up the first workpiece 1. In addition, the diameter of the suction end 0411 is larger than the size of the top of the first workpiece 1 to enhance the stability of the picking head 041 after picking up the first workpiece 1. When the second clamp 05 picks up the second workpiece 2, because the sixth driving component 051 is a clamp cylinder, the first clamping block 052 and the second clamping block 053 can be driven by the sixth driving component. Driven by the actuator 051, the first pressing foot 0521 and the second pressing foot 0531 are separated first, allowing the second workpiece 1 to move between the first pressing foot 0521 and the second pressing foot 0531.
