Technical Field

[0002] When photoresist is stored for a long time or needs to be used with other solvents in a certain ratio, it usually needs to be mixed evenly. At present, one method of mixing photoresist is to use a magnetic stirrer, specifically, by placing a magnetic body into a container containing the colloid to be mixed, and then using a magnetic stirrer to control the directional movement of the magnetic body in the container through magnetism to achieve the mixing of the colloid. However, when the magnetic body is placed in the container, it directly contacts the colloid to be mixed, which is easy to contaminate the colloid to be mixed. Moreover, the magnetic stirrer is only suitable for mixing and stirring a small amount of colloid (for example: 1L), and cannot meet the application requirements of mixing and stirring large quantities of colloids.

[0022] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following illustrative embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention. In addition, the embodiments and features in the embodiments of the present application may be combined with each other without conflict.
[0023] like Figure 1-Figure 3 As shown, an optional embodiment of the utility model provides a photoresist shaker, comprising a base 1, a swing frame 3 pivotally connected to the base 1 by means of a rotating shaft 2, a sealed bottle 5 fixedly loaded on the swing frame 3 and used to contain a colloid 4 to be mixed (which can be a photoresist or a mixture of a photoresist and a corresponding solvent), a driving mechanism 7 used to drive the swing frame 3 to swing periodically around the rotating shaft 2 to cause the colloid 4 in the sealed bottle 5 to flow and mix accordingly in the sealed bottle 5, and a controller 9 connected to the driving mechanism 7 for controlling the working state of the driving mechanism 7, and an elastic clamping seat 30 used to clamp and position the sealed bottle 5 is provided on the swing frame 3.
[0024] The embodiment of the utility model pivotally connects a swing frame 3 on a base 1 which can be driven by a driving mechanism 7 to swing periodically accordingly, and an elastic clamping seat 30 is provided on the swing frame 3 to quickly clamp and fix a sealed bottle 5 containing a colloid 4. The controller 9 controls the driving mechanism 7 to drive the swing frame 3 and the sealed bottle 5 fixed thereon to swing periodically, thereby causing the colloid 4 in the sealed bottle 5 to flow and mix accordingly. During the mixing process, no foreign matter contacts the colloid 4, thereby preventing the colloid 4 from being contaminated. Moreover, sealed bottles 5 of different capacities can be designed according to needs, thereby effectively meeting the large-scale and large-scale stirring and mixing requirements of the colloid 4.
[0025] In an optional embodiment of the present invention, Figure 1 and Figure 3 As shown, the sealed bottle 5 includes a narrow-mouthed bottle body 50 and a sealing cover 52 for sealing the bottle mouth of the narrow-mouthed bottle body 50, and the elastic clamping seat 30 includes a support portion 301 fixedly connected to the swing frame 3 and at least one pair of elastic clamping arms 303 symmetrically extending from the top of the support portion 301 on both sides, and at least one pair of the elastic clamping arms 303 correspondingly clamp the bottleneck of the narrow-mouthed bottle body 50. In this embodiment, the elastic clamping seat 30 uses at least one pair of the elastic clamping arms 303 to clamp the bottleneck of the narrow-mouthed bottle body 50, which can quickly fix the sealed bottle 5. At the same time, the structure of the elastic clamping seat 30 is relatively smaller and convenient to manufacture. In particular, the glue bottle that the photoresist comes with when it leaves the factory can also be directly used as the sealed bottle 5, and only the elastic clamping seat 30 needs to be specifically designed to adapt to it, which is conducive to reducing the equipment cost of the glue shaking machine, and there is no need to pour the photoresist from the original glue bottle to avoid the risk of contamination.
[0026] In an optional embodiment of the utility model, the driving mechanism 7 includes a reduction motor 70 and a crank connecting rod assembly 72 for transmission connection between the motor shaft 701 of the reduction motor 70 and the swing frame 3. In this embodiment, the driving mechanism 7 uses the reduction motor 70 to drive the crank connecting rod assembly 72 to move, and then the crank connecting rod assembly 72 drives the swing frame 3 to swing around the rotating shaft 2, and the overall structure is simple and the cost is low.
[0027] In an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, one end of the swing frame 3 deviating from the rotating shaft 2 is provided with a sliding groove 32 extending in a direction parallel to the axial direction of the rotating shaft 2 and perpendicular to the axial direction of the motor shaft 701, and a slider 34 is slidably assembled in the sliding groove 32. The crank-connecting rod assembly 72 includes a crank 721 with one end vertically connected to the motor shaft 701 of the reduction motor 70 and a connecting rod 723 with one end pivotally connected to the crank 721 away from the motor shaft 701 by means of a ball bearing 723a and the other end pivotally connected to the slider 34. In this embodiment, the reduction motor 70 drives the crank 721 in the crank-connecting rod assembly 72, and then the crank 721 drives the top end of the connecting rod 723 to rise and fall, and finally the connecting rod 723 drives the swing frame 3 to swing periodically around the rotating shaft 2, which can effectively realize the shaking rubber operation; because the connecting rod 723 and the crank 721 are pivotally connected through the ball head bearing 723a, the connecting rod 723 can rotate relative to the crank 721 at different angles, and at the same time, the slider 34 is used to slide in the sliding slot 32 to ensure the smooth movement of the connecting rod 723.
[0028] In an optional embodiment of the present invention, Figure 4As shown, the motor shaft 701 is arranged in parallel with the rotating shaft 2, and the crank-connecting rod assembly 72 includes a crank 721 having one end vertically connected to the motor shaft 701 of the reduction motor 70, and a connecting rod 723 having a bottom end pivotally connected to an end of the crank 721 away from the motor shaft 701 and a top end pivotally connected to an end of the swing frame 3 deviating from the rotating shaft 2. In this embodiment, the motor shaft 701 is arranged in parallel with the rotating shaft 2, so that when assembling the crank-connecting rod assembly 72, each pivot axis of the crank 721 and the connecting rod 723 can be directly arranged in parallel with the motor shaft 701 and the rotating shaft 2, and the assembly structure is simpler.
[0029] In an optional embodiment of the present invention, Figure 5 As shown, the driving mechanism 7 is a linear power member, the housing of the linear power member is pivoted on the base 1 and the output shaft end is pivoted on the bottom surface of one end of the swing frame 3 away from the rotating shaft 2. In this embodiment, the use of a linear power member to output linear power can also drive the swing frame 3 to swing periodically around the rotating shaft 2. During specific implementation, different driving mechanism 5 solutions can be flexibly selected to reduce costs. The linear power member can be a linear motor or a cylinder, etc.
[0030] In an optional embodiment of the present invention, Figure 1 , Figure 4 and Figure 5 As shown, the middle of the rotating shaft 2 is passed through the corresponding protruding pivot seat 36 at the middle of the bottom end of the swing frame 3, and the two ends are respectively pivoted to the shaft seat 10 on the top surface of the base 1 by means of ball bearings 38. In this embodiment, the rotating shaft 2 is assembled in the middle of the bottom end of the swing frame 3, the structural stability of the swing frame 3 is relatively stronger, the space occupied by the overall glue shaker is reduced, and the stroke of the two opposite ends of the sealing bottle 5 during the swinging process is relatively large, which is conducive to the better back and forth flow of the colloid 4 in the sealing bottle 5 and the better mixing effect; the two ends of the rotating shaft 2 are also pivoted to the shaft seat 10 at the top of the base 1 by means of ball bearings 38, so as to ensure the smooth swing of the swing frame 3.
[0031] In an optional embodiment of the present invention, Figure 1 , Figure 4 and Figure 5 As shown, the controller 9 includes a switch unit 90 for the user to control the start and stop of the driving mechanism 7. In this embodiment, the controller 9 has a switch unit 90, which is convenient for the user to control the start and stop of the driving mechanism 7.
[0032] In an optional embodiment of the present invention, Figure 1 , Figure 4 and Figure 5 As shown, the controller 9 also includes at least one of the following units:
[0033] A timing unit 92 for setting the working time of the reduction motor 70; and
[0034] A speed regulating unit 94 is used to set the operating speed of the reduction motor 70 .
[0035] In this embodiment, by setting a timer 92, the user can set the mixing time of the photoresist by himself, and the shaking of the photoresist will be automatically stopped at the time, which is convenient for use; by setting a speed regulator 94, the user can flexibly set the working speed of the reduction motor 5, thereby improving the mixing efficiency of the photoresist.
[0036] In an optional embodiment of the present invention, Figure 1 , Figure 4 and Figure 5 As shown, the base 1 is a hollow frame structure, the swing frame 3 is assembled on the top surface of the base 1, and the driving mechanism 7 is assembled inside the base 1. In this embodiment, the base 1 is designed as a hollow frame structure, which is conducive to the reasonable layout and design of the installation positions of the swing frame 3 and the driving mechanism 7 on the base 1, reducing the occupied space and facilitating movement and transportation.
