Description

Technical Field

[0001] This invention relates to the field of medical device assembly technology, and more particularly to the assembly of the cap and spoon of a sampling cup or sampling tube, specifically a cap and spoon positioning assembly device. Background Technology

[0002] Currently, the assembly process for the caps and spoons that come with sampling cups and tubes is mostly done manually. This not only results in low production efficiency and high labor costs due to long-term manual operation, but also leads to inconsistent assembly accuracy and a large number of defective products. The unique shape of the spoon itself, with its large head and thin handle, is the core challenge for automated assembly.

[0003] Existing simple assembly mechanisms lack a structure that can locate the center point of the spoon handle. During transport, the spoon body is prone to shifting and flipping. During assembly, it is difficult to ensure that the spoon handle and the center hole of the cap are coaxially aligned. Problems such as misalignment and bending of the spoon handle, deformation of the cap, and assembly failure leading to jamming are easily encountered during the fitting process. This results in poor stability during continuous production, severely restricting the efficiency of automated mass production of sampling consumables. Therefore, to solve these problems, we need to design a lid-spoon positioning and assembly device. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] By providing a lid and spoon positioning and assembly device, the assembly of the lid and spoon can be completed automatically. During the assembly process, the spoon can be vertically rotated and then positioned in both horizontal and vertical directions before being fitted into the lid, effectively improving the assembly success rate and production efficiency.

[0006] To address the aforementioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] A lid and spoon positioning assembly device, comprising:

[0008] The mounting base is provided with a left and right positioning assembly mechanism, a front and rear positioning mechanism, and a head cover positioning top mounting mechanism. A steering slide assembly is provided above the front and rear positioning mechanisms. The steering slide assembly consists of several parallel slides. The head cover positioning top mounting mechanism is located in front of the left and right positioning assembly mechanism, and the front and rear positioning mechanism is located above the left and right positioning assembly mechanism.

[0009] In a preferred embodiment of the lid and spoon positioning assembly device of the present invention, the left and right positioning assembly mechanism includes a plurality of first columns fixedly installed on the mounting base, a fixing plate fixedly installed on the first column, guide rods symmetrically slidably connected on the fixing plate, and a lifting platform fixedly installed on the top of the guide rods.

[0010] In a preferred embodiment of the lid and spoon positioning assembly device of the present invention, a lifting drive assembly is fixedly installed at the bottom of the fixing plate, the output end of the lifting drive assembly is fixedly connected to the bottom of the lifting platform, and a plurality of first grippers with drive motors are installed on the lifting platform, and left and right positioning clamping assemblies are provided on the first grippers.

[0011] As a preferred embodiment of the lid and spoon positioning assembly device of the present invention, the left and right positioning clamping components are composed of positioning clamping plates symmetrically slidably mounted on the first clamping claw. The end of the positioning clamping plate away from the first clamping claw is provided with a groove, and the grooves on the pair of positioning clamping plates surround each other to form a clamping groove for positioning clamping.

[0012] In a preferred embodiment of the lid and spoon positioning assembly device of the present invention, the front and rear positioning mechanism includes a plurality of second columns mounted on the fixed plate, and a mounting bracket with a fixing crossbar is fixedly mounted on the second column, and a mounting plate is fixedly mounted on the mounting bracket.

[0013] In a preferred embodiment of the lid and spoon positioning assembly device of the present invention, the mounting plate has several through holes, a funnel is fixedly installed in the through holes of the mounting plate, a positioning plate with multiple arc grooves is fixedly installed on the mounting plate, the arc grooves on the positioning plate fit against the outer wall of the funnel, and the arc grooves on the positioning plate correspond one-to-one with the funnel, and a slide rail assembly is fixedly installed at the bottom of the through holes of the mounting plate, and the funnel corresponds one-to-one with the slide rail of the steering slide rail assembly.

[0014] As a preferred embodiment of the lid and spoon positioning assembly device of the present invention, the slide assembly has second grippers with drive motors on both sides of its outer wall, and front and rear positioning components are symmetrically fixedly installed on the bottom of the second grippers.

[0015] In a preferred embodiment of the lid and spoon positioning assembly device of the present invention, the slide assembly includes a slide installed below the through hole of the mounting plate, the lower end of the slide has a recessed platform, a hanging plate is fitted onto the lower end of the slide, and a mounting base plate is fixedly installed on the lower end of the slide, the mounting base plate being located at the bottom of the hanging plate.

[0016] As a preferred embodiment of the lid and spoon positioning assembly device of the present invention, the lid positioning and mounting mechanism includes a plurality of third columns mounted on the mounting base, a support plate fixedly mounted on the third column, a lifting cylinder fixedly mounted on the support plate, a placement plate fixedly mounted on the lifting cylinder, and a plurality of plungers for positioning the lid equidistantly mounted on the placement plate, the plungers corresponding one-to-one with the slide assembly.

[0017] Compared with existing technologies, the beneficial effects of this invention are as follows: When using this device, by setting up a steering slide assembly, front and rear positioning mechanisms, left and right positioning and assembly mechanisms, and head cover positioning and top mounting mechanisms in linkage, the entire process of sampling spoon reversal, front and rear bidirectional positioning, left and right centering and clamping, spoon cover sleeve, and pressing assembly can be automatically completed. No manual sorting, alignment, or assembly is required, completely eliminating the need for manual assembly. Furthermore, the entire equipment can continuously and uninterruptedly produce in a cyclical manner, with a unit time output far exceeding that of manual assembly, significantly reducing the number of workers and effectively lowering long-term labor and management costs for enterprises. It is suitable for the large-scale automated mass production needs of sampling consumables. It also addresses the challenges posed by the large head, thin handle, and low center of gravity of the sampling spoon. To overcome the structural defects of easy deviation and offset, a cross-shaped bidirectional positioning system is formed by setting up front and rear positioning mechanisms and left and right positioning assembly mechanisms. After the spoon is conveyed by the steering slide assembly, the funnel, slide assembly, and second gripper, together with the front and rear positioning components, complete the front and rear limit of the spoon handle. The first gripper on the lifting platform, together with the grooved left and right positioning clamping components, clamps the left and right sides of the spoon handle, accurately locking the central axis of the spoon handle, ensuring that the spoon handle and the center hole of the lower head cover are strictly coaxial. This overcomes the defects of existing equipment that cannot be centered and that the spoon will flip and deviate during conveying, ensuring that the spoon handle and the center hole of the head cover are completely coaxial, eliminating problems such as bent spoon handle, squeezed and deformed head cover, and material jamming and scrap during assembly, and greatly reducing the defect rate.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention.

[0028] This invention provides an embodiment of a spoon and lid positioning assembly device, which is used to automatically complete the process of turning the spoon, positioning the spoon front and back, positioning the spoon left and right, and assembling the spoon and lid.

[0029] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] Please see Figures 1-6 The present invention provides a lid and spoon positioning and assembly device, comprising:

[0032] Mounting base 1, mounting base 1 is provided with left and right positioning assembly mechanism 2, mounting base 1 is provided with front and rear positioning mechanism 3, mounting base 1 is provided with head cover positioning top mounting mechanism 4, mounting base 1 is provided with steering slide assembly 5 above front and rear positioning mechanism 3, steering slide assembly 5 is composed of several parallel slides, head cover positioning top mounting mechanism 4 is located in front of left and right positioning assembly mechanism 2, and front and rear positioning mechanism 3 is located above left and right positioning assembly mechanism 2.

[0033] In this embodiment, the specific usage process is as follows:

[0034] When using the device, for the spoon 6 horizontally fed out by the spoon feeding device, the spoon handle is facing forward so that it enters the slide of the turning slide assembly 5. The spoon 6 slides down the turning slide assembly 5 under the action of gravity and changes direction to the vertical direction, falling into the front and rear positioning mechanism 3. The front and rear positioning mechanism 3 positions it front and back, and then the left and right positioning assembly mechanism 2 clamps and positions the spoon handle part of the spoon 3 left and right. After clamping, the spoon 3 is pulled down so that the spoon 3 is released from the front and rear positioning mechanism 3. After the left and right positioning assembly mechanism 2 pulls down the spoon 6, the spoon 6 moves to the head cover positioning top mounting mechanism 4 and the left and right positioned spoon 6 is sleeved into the center hole of the head cover 7. Then the head cover positioning top mounting mechanism 4 moves up and the left and right positioning assembly mechanism 2 moves down so that the spoon 6 and the head cover 7 are assembled.

[0035] Example 2

[0036] Please see Figures 1-6 The front and rear positioning mechanism 3 includes several second columns 301 mounted on a fixed plate 202. A mounting bracket 302 with a fixed crossbar is fixedly mounted on each second column 301, and a mounting plate 303 is fixedly mounted on the mounting bracket 302. The mounting plate 303 has several through holes, and a funnel 305 is fixedly mounted in each of these through holes. A positioning plate 304 with multiple arc grooves is fixedly mounted on the mounting plate 303. The arc grooves on the positioning plate 304 fit against the outer wall of the funnel 305, and each arc groove on the positioning plate 304 corresponds to a funnel 305. A slide rail assembly 306 is fixedly mounted at the bottom of each through hole in the mounting plate 303, and each funnel 305 corresponds to a slide rail in the steering slide rail assembly 5. Second grippers 307 with drive motors are provided on both sides of the outer wall of the slide rail assembly 306, and front and rear positioning components 308 are symmetrically fixedly mounted at the bottom of each second gripper 307. The slide rail assembly 306 includes a slide rail 3061 installed below the through hole of the mounting plate 303. The lower end of the slide rail 3061 has a recessed platform. A suspension plate 3062 is fitted onto the lower end of the slide rail 3061. A mounting base plate 3063 is fixedly installed on the lower end of the slide rail 3061. The mounting base plate 3063 is located at the bottom of the suspension plate 3062.

[0037] In this embodiment, when the spoon 6 slides down the turning slide assembly 5 under the action of gravity and changes direction to vertical, and falls into the funnel 305 of the front and rear positioning mechanism 3, the spoon 6 will slide down from the through hole at the bottom of the funnel 305. After falling into the slide 3061 of the slide assembly 306, it will continue to slide down until the spoon head of the spoon 6 is suspended on the suspension plate 3062 and the spoon handle extends downward out of the slide assembly 306. Then, the drive motor of the second gripper 307 moves the second gripper 307 back and forth, thereby driving the front and rear positioning assembly 308 to tighten the spoon handle, thereby realizing the front and rear positioning action of the spoon 6. At this time, the left and right positioning assembly mechanism 2 is located below the spoon handle, and since the contact part between the suspension plate 3062 and the spoon 6 is made of silicone, the suspension plate 3062 can deform when subjected to external force.

[0038] Example 3

[0039] Please see Figures 1-5 The left and right positioning assembly mechanism 2 includes several first columns 201 fixedly installed on the mounting base 1. A fixing plate 202 is fixedly installed on the first column 201. Guide rods 206 are symmetrically slidably connected to the fixing plate 202. A lifting platform 203 is fixedly installed on the top of the guide rods 206. A lifting drive assembly 207 is fixedly installed on the bottom of the fixing plate 202. The output end of the lifting drive assembly 207 is fixedly connected to the bottom of the lifting platform 203. Several first grippers 204 with drive motors are installed on the lifting platform 203. Left and right positioning clamping assemblies 205 are provided on the first grippers 204. The left and right positioning clamping assemblies 205 are composed of positioning clamping plates 2051 symmetrically slidably installed on the first grippers 204. A groove 2052 is opened at the end of the positioning clamping plate 2051 away from the first gripper 204. The grooves 2052 on a pair of positioning clamping plates 2051 surround to form a clamping groove for positioning clamping.

[0040] In this embodiment, after the front and rear positioning mechanism 3 completes the front and rear positioning of the spoon 6, since the left and right positioning clamping components 205 are initially in an open state, the lifting drive component 207 of the left and right positioning assembly mechanism 2 rises, which drives the lifting platform 203 and the first gripper 204 mounted on the lifting platform 203 to rise to the lower part of the spoon handle of the spoon 6. Then, the first gripper 204 is driven by the drive motor to move the first gripper 204 to the middle position, which can drive the positioning clamping plate 2051 to approach the lower part of the spoon handle of the spoon 6, and clamp the spoon 6 left and right through the groove 2052. Then, the lifting drive assembly 207 descends, pulling the spoon 6 out of the slide assembly 306. During the pulling process, the silicone suspension plate 3062 deforms, making it easier to pull out the spoon 6. After the spoon 6 is pulled out, the lifting drive assembly 207 drives the lifting platform 203 to descend, thereby driving the spoon 6, which has completed front-back, left-right positioning, to fit into the center hole of the head cover 7. Furthermore, when the lifting drive assembly 207 drives the lifting platform 203 to rise and fall, the guide rod 206 fixed to the bottom of the lifting platform 203 slides on the fixed plate 202, which can guide and position the lifting platform 203.

[0041] Example 4

[0042] Please see Figures 1-4 The head cover positioning and mounting mechanism 4 includes several third columns 401 mounted on the mounting base 1. A support plate 402 is fixedly mounted on the third column 401. A lifting cylinder 403 is fixedly mounted on the support plate 402. A placement plate 404 is fixedly mounted on the lifting cylinder 403. Multiple plungers 405 for positioning the head cover are equidistantly mounted on the placement plate 404. Each plunger 405 corresponds to a slide assembly 306.

[0043] In this embodiment, when the spoon 6 is fitted into the center hole of the head cover 7, the lifting cylinder 403 of the head cover positioning and mounting mechanism 4 rises, driving the plunger 405 to rise, and in conjunction with the lifting drive component 207 of the left and right positioning assembly mechanism 2, driving the lifting platform 203 to descend, so that the spoon 6 can be fitted into the center hole of the head cover 7, completing the assembly of the spoon 6 and the head cover 7. After the assembly is completed, the first gripper 204 of the left and right positioning assembly mechanism 2 is released and returns to its original position, completing one work cycle.

[0044] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
