Description

Technical Field

[0001] This utility model relates to the field of petri dish packaging, and more specifically, to a petri dish packaging machine with a gripping structure. Background Technology

[0002] A petri dish is a laboratory vessel used for culturing microorganisms or cells. It consists of a flat, disc-shaped base and a lid, and is generally made of glass or plastic. Packaging petri dishes requires a gripping mechanism to lift them from a conveyor belt onto a packaging machine. However, current methods for packaging petri dishes still have the following drawbacks:

[0003] Traditionally, when packaging petri dishes, operators manually pick them up from the conveyor belt and then transfer them to the packaging machine. This manual operation involves direct contact between operators and the edges of the petri dishes, increasing the risk of microbial contamination, and also wastes considerable manpower. Therefore, a petri dish packaging machine with a gripping structure is proposed. Utility Model Content

[0004] The purpose of this invention is to address the current problem that when packaging petri dishes, operators typically pick them up manually from the conveyor belt and then transfer them to the packaging machine. This manual operation results in operators directly contacting the edges of the petri dishes, which can easily introduce microbial contamination. Furthermore, manual operation wastes a significant amount of manpower.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] The present invention is as follows: a petri dish packaging machine with a gripping structure, including a packaging machine body, a gripping mechanism for gripping petri dishes is provided on the outside of the packaging machine body, and a moving component for adjusting the position of the petri dishes is provided on the gripping mechanism;

[0007] The gripping mechanism includes a housing located above the main body of the packaging machine. A first motor is fixedly connected to the inner top wall of the housing. A first lead screw is fixedly connected to the output end of the first motor. A collar is threaded onto the outer side of the first lead screw. A first connecting rod and a second connecting rod are hinged to the outer wall of the collar. A fixed post is fixedly connected to the inner wall of the housing. A third connecting rod is hinged to the outer wall of the fixed post. The third connecting rod is hinged to the first connecting rod. A clamping arm is hinged to the other end of the first and second connecting rods. An arc-shaped block is bolted to the bottom side wall of the clamping arm.

[0008] As a preferred technical solution of this utility model, the moving component includes a support frame bolted to the outer wall of the packaging machine body, a second lead screw rotatably connected to the side wall of the support frame, a slider threaded to the external of the second lead screw, a second motor bolted to the outer wall of the support frame and coaxial with the second lead screw, and a connecting component provided at the bottom of the slider.

[0009] As a preferred technical solution of this utility model, the connecting assembly includes a cylinder fixedly connected to the bottom of the slider, and a mounting plate is fixedly connected to the telescopic end of the cylinder, and the mounting plate is bolted to the housing.

[0010] As a preferred technical solution of this utility model, a strip-shaped hole is provided on the side wall of the housing, and a guide plate is fixedly connected to the outer wall of the collar, and the guide plate is slidably connected to the strip-shaped hole.

[0011] As a preferred technical solution of this utility model, rectangular blocks are fixedly connected to the opposite side walls of the slider, and round rods are fixedly connected to the opposite side walls inside the support frame. One end of the round rod passes through the rectangular block and is slidably connected to the rectangular block.

[0012] As a preferred technical solution of this utility model, a plurality of anti-slip protrusions are provided on the side wall of the arc-shaped block away from the clamping arm, and the material of the plurality of anti-slip protrusions is silicone.

[0013] As a preferred technical solution of this utility model, protective baffles are fixedly connected to the opposite side walls of the shell, and both protective baffles are acrylic plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The gripping mechanism is designed so that when in use, the first motor is started, which drives the first lead screw to rotate, thereby causing the collar to rise. At this time, the collar also drives the first connecting rod and the second connecting rod to rise. Then, due to the restriction of the third connecting rod, the two clamping arms and the arc-shaped block will move closer to each other, thereby clamping multiple culture dishes located inside the two arc-shaped blocks. By adopting this method, no manual operation is required, reducing the probability of microbial infection.

[0016] 2. By using the set moving component, the second motor is activated when in use. The second motor drives the slider, connecting component and gripping mechanism to move, thereby adjusting the position of the culture dish clamped by the arc block, which can place the culture dish in different positions and has a wide range of applications.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0024] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] like Figure 1As shown, this embodiment proposes a petri dish packaging machine with a gripping structure, including a packaging machine body 1, a gripping mechanism 2 for gripping petri dishes is provided on the outside of the packaging machine body 1, and a moving component 3 for adjusting the position of the petri dishes is provided on the gripping mechanism 2.

[0028] like Figure 3 and Figure 5 As shown, the gripping mechanism 2 includes a housing 201 located above the packaging machine body 1. A first motor 202 is fixedly connected to the inner top wall of the housing 201. A first lead screw 203 is fixedly connected to the output end of the first motor 202. A collar 204 is threaded onto the outer side of the first lead screw 203. The first motor 202 drives the first lead screw 203 to rotate, thereby adjusting the position of the collar 204. A first connecting rod 205 and a second connecting rod 206 are hinged to the outer wall of the collar 204. A fixing post 207 is fixedly connected to the inner wall of the housing 201. A third connecting rod 208 is hinged to the outer wall of the fixing post 207. The third connecting rod 208 is hinged to the first connecting rod 205. A clamping arm 209 is hinged to the other end of the first connecting rod 205 and the second connecting rod 206. The lifting and lowering of the collar 204 drives the lifting and lowering of the first connecting rod 205 and the second connecting rod 206. 208 serves to restrict the positions of the first connecting rod 205, the second connecting rod 206, and the clamping arm 209. An arc-shaped block 210 is bolted to the bottom side wall of the clamping arm 209, which can clamp the culture dish. There are two of each of the following: the first connecting rod 205, the second connecting rod 206, the fixing column 207, the third connecting rod 208, the clamping arm 209, and the arc-shaped block 210, which are arranged opposite to each other. When it is necessary to clamp the culture dish located at the top of the packaging machine body 1, the first motor 202 is started, which causes the first lead screw 203 to rotate. Then the collar 204 rises. When the collar 204 rises, the first connecting rod 205 moves downward with the connection point with the third connecting rod 208 as the fulcrum, thereby bringing the two clamping arms 209 and the arc-shaped block 210 closer together and clamping the culture dish. If it is necessary to remove the culture dish, the first motor 202 is started, and its output end is reversed.

[0029] like Figure 1 and Figure 3 As shown, the moving component 3 includes a support frame 301 bolted to the outer wall of the packaging machine body 1. A second lead screw 302 is rotatably connected to the side wall of the support frame 301. A slider 303 is threaded onto the outside of the second lead screw 302. The rotation of the second lead screw 302 can adjust the position of the slider 303. A second motor 304 is bolted to the outer wall of the support frame 301 and is coaxial with the second lead screw 302. The second motor 304 drives the second lead screw 302 to rotate. A connecting component 305 is provided at the bottom of the slider 303. When in use, the second motor 304 is started, and the second motor 304 drives the connecting component 305 and the petri dish clamped by the arc-shaped block 210 to move, thereby adjusting the position of the petri dish.

[0030] like Figure 3 As shown, the connecting assembly 305 includes a cylinder 3051 fixedly connected to the bottom of the slider 303. The telescopic end of the cylinder 3051 is fixedly connected to a mounting plate 3052. The mounting plate 3052 is bolted to the housing 201. In use, the position of the gripping mechanism 2 can be adjusted by extending and retracting the telescopic end of the cylinder 3051.

[0031] like Figure 4 As shown, a strip hole 4 is provided on the side wall of the housing 201, and a guide plate 5 is fixedly connected to the outer wall of the collar 204. The guide plate 5 is slidably connected to the strip hole 4. When the first lead screw 203 rotates and drives the collar 204 to move, the guide plate 5 will move along the strip hole 4 to avoid excessive friction between the first lead screw 203 and the collar 204, which would cause the clamping arm 209 to rotate with the collar 204.

[0032] like Figure 1 As shown, rectangular blocks 6 are fixedly connected to the opposite side walls of the slider 303, and round rods 7 are fixedly connected to the opposite side walls inside the support frame 301. One end of the round rod 7 passes through the rectangular block 6 and is slidably connected to the rectangular block 6. When the second motor 304 drives the second lead screw 302 to rotate, if the friction between the second lead screw 302 and the slider 303 is large, it may cause the slider 303 to rotate. At this time, the two round rods 7 can limit the two rectangular blocks 6 and the slider 303, thereby improving the stability of the slider 303 when it moves.

[0033] like Figure 1 As shown, the side wall of the arc-shaped block 210 away from the clamping arm 209 is provided with several anti-slip protrusions. The material of the several anti-slip protrusions is silicone. The several anti-slip protrusions can prevent the arc-shaped block 210 from slipping between itself and the culture dish.

[0034] like Figure 5 As shown, protective baffles 8 are fixedly connected to the opposite side walls of the housing 201. Both protective baffles 8 are made of acrylic sheets. When in use, the two protective baffles 8 can shield the two sides of the first motor 202, effectively preventing external debris from contacting the first motor 202 and causing it to be damaged.

[0035] Specifically, when using this petri dish packaging machine with a gripping structure: connect the first motor 202, the second motor 304, and the cylinder 3051 to an external power source. If it is necessary to grip the petri dish located at the top of the packaging machine body 1, then activate the cylinder 3051. The operation of the cylinder 3051 will cause the housing 201 to descend (e.g., Figure 3 As shown), until the bottom of the arc-shaped block 210 is in contact with the top of the packaging machine body 1 (as shown). Figure 3(As shown), then the first motor 202 is started, causing the first lead screw 203 to rotate. Next, the collar 204 rises. As the collar 204 rises, the first connecting rod 205 moves downwards with its connection point with the third connecting rod 208 as a fulcrum, thereby bringing the two clamping arms 209 and the arc-shaped block 210 closer together, thus clamping the culture dish (as shown). Figure 5 As shown), to remove the petri dish, start the first motor 202 to reverse its output. Then, to adjust the position of the petri dish clamped by the two arc-shaped blocks 210, start the second motor 304. The second motor 304 drives the lead screw to rotate, and then the slider 303, cylinder 3051, mounting plate 3052, and the petri dish clamped by the arc-shaped blocks 210 move (as shown). Figure 3 (As shown).

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
