A tray conveying mechanism for a syringe magazine

Abstract

This application relates to the field of conveying mechanism technology and discloses a tray conveying mechanism for injection boxes, including a conveyor belt assembly and a lateral adjustment assembly. This tray conveying mechanism for injection boxes uses a dual-axis motor to drive two first bevel gears to rotate synchronously, which in turn drives a second bevel gear and a first lead screw to rotate, causing the moving plate to rise and fall precisely along the guide post, thus achieving vertical position adjustment of the guide rail side plate. In the lateral adjustment assembly, a servo motor drives two second sprockets to rotate via two chains, which in turn drives two second lead screws to rotate synchronously. This causes two corresponding connecting sleeves to push the guide rail side plate to slide laterally along the limiting post, completing the horizontal spacing adjustment. The synergistic effect of vertical and lateral adjustments allows the guide rail side plate to be flexibly positioned in multiple dimensions, ensuring precise alignment between the tray groove and the injection bottle, reducing assembly errors. It is also compatible with various tray sizes, significantly improving production flexibility and efficiency, making it more practical.

Description

Technical Field

[0001] This application relates to the field of conveying mechanism technology, specifically a tray conveying mechanism for injection cartridges. Background Technology

[0002] After the injection vials are filled, they need to be placed into a tray, and then the tray is placed into a packaging box.

[0003] In related technologies, the above assembly process has been automated; the injection vials are transported by rail to a tray on a horizontal conveyor belt, and then the cartoning mechanism puts the tray into a packaging box and completes the sealing of the packaging box.

[0004] Since the number and position of the grooves on the tray for placing injection vials are fixed, it is necessary to ensure that the injection vials fall perfectly into the grooves on the tray during the production process. This places high demands on the tray's running speed and route. However, most related technologies rely on the friction between the tray and the conveyor belt to maintain a relatively fixed position, or a guide rail is fixed on the conveyor belt so that the tray moves along the direction of the guide rail. However, these methods are relatively rigid and cannot be flexibly adjusted to meet the precision requirements of assembly. To solve the above problems, a tray conveying mechanism for injection boxes is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a tray conveying mechanism for injection vials, which can flexibly adjust the position of the guide rails on the conveyor belt, thereby adjusting the conveying route of the tray and ensuring the assembly accuracy of the tray and injection vials.

[0006] To achieve the above objectives, this application provides the following technical solution: a tray conveying mechanism for injection boxes, comprising a conveyor belt assembly and a lateral adjustment assembly. Two guide rail side plates are provided above the conveyor belt assembly, and a vertical adjustment assembly is provided below the conveyor belt assembly. The vertical adjustment assembly includes a dual-axis motor fixedly connected to the bottom surface of the conveyor belt assembly. A first bevel gear is fixedly connected to each of the two output shafts of the dual-axis motor. Rotatable first lead screws are installed on both sides of the outer surface of the conveyor belt assembly. A second bevel gear is fixedly connected to the bottom end of each first lead screw. A movable plate is threadedly connected to the outer surface of each first lead screw, and a connecting frame is fixedly connected to the outer surface of each movable plate.

[0007] The lateral adjustment assembly includes four second lead screws, which are rotatably sleeved on the top of the two connecting frames. Each second lead screw has a connecting sleeve block threaded onto its outer surface. The four connecting sleeve blocks are fixedly connected to the opposite side of the two guide rail side plates. Each connecting sleeve block has a first sprocket fixedly connected to its rotating shaft end.

[0008] The above solution uses a dual-axis motor to drive two first bevel gears to rotate synchronously, which in turn drives the second bevel gear and the first lead screw to rotate, enabling precise lifting and lowering of the moving plate. This achieves vertical position adjustment of the guide rail side plate. When the two first sprockets in the lateral adjustment assembly rotate synchronously, they cause the two second lead screws to rotate synchronously. This allows the two connecting sleeves to push the corresponding guide rail side plate to slide laterally along the limiting post, completing the horizontal spacing adjustment. The synergistic effect of vertical and lateral adjustments allows the guide rail side plate to be flexibly positioned in multiple dimensions, ensuring precise alignment between the tray groove and the injection bottle, reducing assembly errors. It is also compatible with various tray sizes, significantly improving production flexibility and efficiency, and making it more practical.

[0009] Furthermore, two sets of guide posts are installed on both sides of the outer surface of the conveyor belt assembly, and the two movable plates are slidably sleeved on the outer surface of the four sets of guide posts.

[0010] The above scheme allows the guide column to limit the trajectory of the moving plate, and the rotation of the second bevel gear can drive the moving plate to move up and down.

[0011] Furthermore, two reinforcing blocks are fixedly connected to the bottom surface of the conveyor belt assembly, and the outer surfaces of the two output shafts of the dual-axis motor are respectively rotatably sleeved on the inner walls of the two reinforcing blocks.

[0012] The above solution, through the reinforcement blocks, can make the two shafts of the dual-axis motor more stable when rotating.

[0013] Furthermore, a servo motor is fixedly connected to the inner side of each of the connecting frames, and two second sprockets are fixedly connected to the output shaft end of each of the servo motors.

[0014] With the above scheme, when the servo motor starts, it will drive the corresponding two second sprockets to rotate.

[0015] Furthermore, each of the second sprockets is equipped with a chain on its exterior, and the four second sprockets are respectively connected to the four first sprockets via the four chains.

[0016] The above solution allows for convenient transmission between the second and first sprockets via a specially designed chain, making it easy to use.

[0017] Furthermore, each of the two connecting frames is slidably fitted with a limiting post at its top, and the ends of the two limiting posts that are close to each other are respectively fixedly connected to the sides of the two guide rail side plates that are far apart from each other.

[0018] The above scheme allows for further limitation of the movement trajectory of the guide rail side plate by setting limit posts, enabling the guide rail side plate to perform lateral position adjustment work more stably.

[0019] Furthermore, the two second bevel gears mesh with the two first bevel gears respectively.

[0020] With the above scheme, when the dual-shaft motor starts, it can drive two second bevel gears to rotate simultaneously through two first bevel gears.

[0021] Furthermore, support piles are fixedly connected to the four corners of the bottom surface of the conveyor belt assembly, and anti-slip mats are fixedly connected to the ground of each support pile.

[0022] The above solution, through the installation of support piles and anti-slip mats, can improve the stability of the conveyor belt assembly placed on the ground, thereby optimizing the conveying process.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This tray conveying mechanism for injection cartridges uses a dual-axis motor to drive two first bevel gears to rotate synchronously, which in turn drives a second bevel gear and a first lead screw to rotate. This allows the moving plate to move precisely up and down along the guide post, achieving vertical position adjustment of the guide rail side plate. In the lateral adjustment assembly, a servo motor drives two second sprockets to rotate through two chains, which in turn drives two second lead screws to rotate synchronously. This causes the corresponding two connecting sleeves to push the guide rail side plate to slide laterally along the limiting post, completing the horizontal spacing adjustment. The synergistic effect of vertical and lateral adjustments allows the guide rail side plate to be flexibly positioned in multiple dimensions, ensuring precise alignment between the tray groove and the injection bottle, reducing assembly errors. It is also compatible with various tray sizes, significantly improving production flexibility and efficiency, and making it more practical. Attached Figure Description

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 4 and Figure 5 In this embodiment, a tray conveying mechanism for an injection box includes a conveyor belt assembly 1 and a lateral adjustment assembly 4. Support piles 5 are fixedly connected to the four corners of the bottom surface of the conveyor belt assembly 1, and anti-slip mats are fixedly connected to the ground of each support pile 5. The support piles 5 and anti-slip mats can improve the stability of the conveyor belt assembly 1 on the ground, thereby optimizing the conveying process. Two guide rail side plates 2 are provided above the conveyor belt assembly 1, and a vertical adjustment assembly 3 is provided below the conveyor belt assembly 1.

[0034] Please see Figure 2 , Figure 4 and Figure 5 The vertical adjustment component 3 includes a dual-axis motor 301 fixedly connected to the bottom surface of the conveyor belt assembly 1. Two reinforcing blocks 308 are fixedly connected to the bottom surface of the conveyor belt assembly 1. The outer surfaces of the two output shafts of the dual-axis motor 301 are respectively rotatably sleeved on the inner walls of the two reinforcing blocks 308. The reinforcing blocks 308 can make the two shafts of the dual-axis motor 301 more stable when rotating. A first bevel gear 302 is fixedly connected to the two output shaft ends of the dual-axis motor 301. Rotatable first lead screws 303 are installed on both sides of the outer surface of the conveyor belt assembly 1. A second bevel gear 305 is fixedly connected to the bottom end of each first lead screw 303.

[0035] Please see Figure 2 , Figure 4 and Figure 5Two second bevel gears 305 mesh with two first bevel gears 302 respectively. When the dual-shaft motor 301 starts, it can drive the two second bevel gears 305 to rotate simultaneously through the two first bevel gears 302. The outer surface of each first lead screw 303 is threaded with a moving plate 306. Two sets of guide posts 304 are installed on both sides of the outer surface of the conveyor belt assembly 1. The two sides of the moving plate 306 are slidably sleeved on the outer surface of the four sets of guide posts 304 respectively. The guide posts 304 can limit the trajectory of the moving plate 306. When the second bevel gear 305 rotates, it can drive the moving plate 306 to move up and down. The outer surface of each moving plate 306 is fixedly connected with a connecting frame 307. The connecting frame 307 can move synchronously with the moving plate 306.

[0036] Please see Figure 3 , Figure 4 and Figure 5 The lateral adjustment assembly 4 includes four second lead screws 401, which are rotatably mounted on the top of two connecting frames 307. Each second lead screw 401 has a connecting sleeve 402 threaded onto its outer surface. The four connecting sleeves 402 are fixedly connected to the opposite sides of the two guide rail side plates 2. Each connecting sleeve 402 has a first sprocket 403 fixedly connected to its shaft end. Each connecting frame 307 has a servo motor 404 fixedly connected to its inner side. Each servo motor 404 has two second sprockets 405 fixedly connected to its output shaft end. When the servo motor 404 starts, it drives the corresponding two second sprockets 405 to rotate. Each second sprocket 405 is equipped with a chain 406 on its exterior. The four second sprockets 405 are respectively connected to the four first sprockets 403 via the four chains 406. The chains 406 facilitate the transmission between the second sprockets 405 and the first sprockets 403, making it convenient to use. The tops of the two connecting frames 307 are each slidably fitted with limiting posts 407. The ends of the two limiting posts 407 that are close to each other are respectively fixedly connected to the sides of the two guide rail side plates 2 that are far apart from each other. The limiting posts 407 can further limit the movement trajectory of the guide rail side plates 2, enabling the guide rail side plates 2 to perform lateral position adjustment work more stably.

[0037] In this embodiment, the tray conveying mechanism for an injection box is driven by a dual-axis motor 301 to rotate two first bevel gears 302 synchronously, which in turn drive a second bevel gear 305 and a first lead screw 303 to rotate. This causes the moving plate 306 to move precisely up and down along the guide post 304, achieving vertical position adjustment of the guide rail side plate 2. In the lateral adjustment assembly 4, a servo motor 404 drives two second sprockets 405 to rotate in conjunction with two first sprockets 403 via two chains 406. This, in turn, drives two second lead screws 401 to rotate synchronously, causing the corresponding two connecting sleeves 402 to push the guide rail side plate 2 to slide laterally along the limiting post 407, thus completing the horizontal spacing adjustment. The synergistic effect of vertical and lateral adjustments allows the guide rail side plate 2 to be flexibly positioned in multiple dimensions, ensuring precise alignment between the tray groove and the injection bottle, reducing assembly errors. It is also compatible with various tray specifications, significantly improving production flexibility and efficiency, and making it more practical.

[0038] The working principle of the above embodiment is as follows: When the dual-axis motor 301 is started, its two output shafts synchronously drive the two first bevel gears 302 to rotate. The two meshing second bevel gears 305 drive the first lead screws 303 on both sides to rotate. Since the moving plate 306 is threadedly connected to the first lead screw 303 and its two sides are slidably sleeved on the guide post 304, the rotation of the first lead screw 303 will push the moving plate 306 to rise and fall vertically along the guide post 304. Thus, the connecting frame 307 drives the guide rail side plate 2 to adjust its vertical height as a whole, matching the falling trajectory of the injection bottle. At the same time, the servo motor 404 of the horizontal adjustment component 4 is started, driving the corresponding second sprocket 405 to rotate. The chain 406 links the first sprocket 403, causing the two second lead screws 401 to rotate synchronously. As the connecting sleeve 402 is threadedly connected to the second lead screw 401 and fixed to the side of the guide rail side plate 2, the rotation of the two corresponding second lead screws 401 will push the guide rail side plate 2 to slide laterally along the limiting post 407, adjusting the horizontal distance between the two guide rails to adapt to the groove distribution of different specifications of pallets. During the vertical and horizontal adjustment process, the guide post 304 and the limiting post 407 respectively restrict the movement path of the moving plate 306 and the guide rail side plate 2 to ensure adjustment accuracy. The support pile 5 and the anti-slip pad enhance the contact stability between the mechanism and the ground and reduce vibration interference. Finally, the multi-dimensional flexible positioning of the guide rail side plate 2 ensures that the pallet is always transported along the optimized path on the conveyor belt assembly 1, and the injection bottle falls accurately into the center of the groove, reducing assembly errors and realizing efficient and high-precision automated boxing operations.
