Description

Technical Field

[0001] This utility model relates to the technical field of adhesive testing, and in particular to an electrophoresis apparatus for a steel plate used in adhesive testing. Background Technology

[0002] In current automobile production, there are many types of steel sheet materials used for the car body. Commonly used steel sheet materials include ordinary steel sheet, galvanized steel sheet, and aluminum sheet. Each type of steel sheet includes multiple models. During the automobile production process, each time a different material or model of steel sheet is used, a corresponding material or model of steel sheet is needed as a test steel sheet for adhesives to test the performance of automotive adhesives. Before bonding with automotive adhesives, these test steel sheets need to undergo degreasing, phosphating, and electrophoresis treatments. Furthermore, all subsequent tests of automotive adhesives are conducted on the electrophoresis-treated test steel sheets.

[0003] The commonly used apparatus for electrophoresis of steel plates used in adhesive experiments is the industrial electrophoresis apparatus. This requires hanging the steel plate on a car and performing electrophoresis on the car production line. The entire process must be completed in the car production workshop. Industrial electrophoresis apparatus is large in size and complicated to operate. Furthermore, the steel plate hanging on the car is prone to scratching and damaging the car body, making it unsuitable for laboratory applications.

[0004] Current laboratory electrophoresis apparatuses typically feature a lifting fixture, with steel plates suspended on the fixture and moving up and down with it. However, this structure does not allow for flexible addition of steel plate samples during electrophoresis. Each batch of steel plates must be electrophoresed before the next batch can be loaded for electrophoresis, which consumes time for suspending and unloading the steel plates, resulting in low utilization of existing laboratory electrophoresis apparatuses.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0029] Please see Figures 1 to 4 To solve the above-mentioned technical problems, this utility model proposes an electrophoresis device for steel plates used in adhesive experiments, comprising: an electrophoresis stage 1 and a sample injection assembly 2;

[0030] The electrophoresis stage 1 is provided with an electrophoresis tank 10 for loading electrophoresis solution inside, and the upper end face of the electrophoresis stage 1 is provided with a first opening that communicates with the electrophoresis tank 10.

[0031] The sample injection assembly 2 includes a fixed frame 21, a rotating shaft 22, a rotating hanging plate 23, a driving component 24, and multiple hooks 25;

[0032] The fixed frame 21 is fixedly connected to the electrophoresis table 1. The rotating hanging plate 23 has a shaft hole through it along the plate surface. One end of the rotating shaft 22 is rotatably connected to the fixed frame 21. The other end of the rotating shaft 22 passes through the shaft hole and is fixedly connected to the driving member 24. The rotating shaft 22 and the rotating hanging plate 23 are fixedly connected.

[0033] The shaft hole is located at the central axis of the rotating hanging plate 23. The rotation axis of the rotating shaft 22 is parallel to the horizontal ground, and the horizontal plane where the rotating shaft 22 is located is higher than the horizontal plane where the first opening is located.

[0034] The driving component 24 is used to drive the rotating shaft 22 to rotate along the fixed frame 21, so as to drive the rotating hanging plate 23 to rotate relative to the fixed frame 21. During the rotation of the rotating hanging plate 23, the part of the rotating hanging plate 23 located below the rotating shaft 22 is located in the electrophoresis tank 10.

[0035] The plurality of hooks 25 are fixedly connected to the rotating hanging plate 23, and the plurality of hooks 25 are respectively arranged along the circumferential direction of the rotating hanging plate 23.

[0036] Specifically, by arranging multiple hooks 25 along the circumferential direction of the rotating hanging plate 23, each hook 25 can suspend one of the adhesive experimental steel plates. During electrophoresis, the rotating hanging plate 23 can rotate with the rotating shaft 22, allowing the multiple adhesive experimental steel plates to change their relative positions with the electrophoresis tank 10. Simultaneously, since the horizontal plane of the rotating shaft 22 is higher than the horizontal plane of the first opening, when the rotating hanging plate 23 rotates with the rotating shaft 22, the section of the rotating hanging plate 23 located below the rotating shaft 22 is inside the electrophoresis tank 10. This allows each adhesive experimental steel plate to sequentially enter the electrophoresis tank 10 and contact the electrophoretic solution as the rotating hanging plate 23 rotates (ensuring the adhesive experimental steel plate is completely immersed in the electrophoretic solution for at least 10 seconds), and then leave the electrophoresis tank 10 as the rotating hanging plate 23 rotates, thus completing the electrophoresis operation.

[0037] It is understandable that during the continuous rotation of the rotating hanging plate 23, there can be simultaneously a steel plate for adhesive experiments to be placed into the electrophoresis tank 10 for electrophoresis, a steel plate for adhesive experiments undergoing electrophoresis in the electrophoresis tank 10, and a steel plate for adhesive experiments that has completed electrophoresis and left the electrophoresis tank 10. Once the steel plate for adhesive experiments leaves the electrophoresis tank 10, the experimenter can use insulated tools to remove the steel plate for adhesive experiments that has completed electrophoresis, and can then reinsert a steel plate for adhesive experiments that has not undergone electrophoresis, thus ensuring the experiment... The novel electrophoresis apparatus for adhesive experimental steel plates allows for the flexible addition of other un-electrophoresed steel plates while some are being electrophoresed within the electrophoresis tank 10. This reduces waiting time for suspending and removing the steel plates, thereby improving the utilization rate of the apparatus. It also solves the problem of low utilization rates in existing laboratory electrophoresis apparatuses, which cannot flexibly add steel plate samples during electrophoresis and require waiting time for suspending and removing the plates.

[0038] Please see Figure 2 and Figure 3 Furthermore, the fixing frame 21 includes a main support frame 211 and a connecting frame 212;

[0039] The lower end of the main support frame 211 is fixedly connected to the side wall of the electrophoresis table 1;

[0040] The connecting frame 212 includes a horizontal bar 2121 and a vertical bar 2122. One end of the horizontal bar 2121 is connected to the end of the main support frame 211 away from the electrophoresis table 1. The other end of the horizontal bar 2121 extends horizontally away from the main support frame 211, and the horizontal bar 2121 is located in the height direction of the electrophoresis tank 10.

[0041] The upper end of the vertical rod 2122 is fixedly connected to the end of the horizontal rod 2121 away from the main support frame 211, and the lower end of the vertical rod 2122 is rotatably connected to the rotating shaft 22. The vertical rod 2122 and the horizontal rod 2121 are arranged perpendicular to each other, and the vertical rod 2122 and the rotating shaft 22 are arranged perpendicular to each other, with the rotating shaft 22 located directly below the horizontal rod 2121.

[0042] The end of the rotating shaft 22 away from the vertical rod 2122 passes through the shaft hole toward the main support frame 211 and is then fixedly connected to the driving component 24.

[0043] By setting the main support frame 211 and the connecting frame 212, the end of the rotating shaft 22 away from the vertical rod 2122 is connected to the rotating hanging plate 23 in the direction of the main support frame 211, so that the rotating hanging plate 23 can be located between the vertical rod 2122 and the main support frame 211. This allows the rotating hanging plate 23 to be easily rotated in the height direction of the electrophoresis tank 10, making it convenient to rotate the steel plate for adhesive experiment into the electrophoresis tank 10 for electrophoresis.

[0044] To further explain, the hook 25 is made of insulating material, and the rotating hanging plate 23 can also be made of insulating material, or an insulating paint can be sprayed onto the surface of the rotating hanging plate 23 to achieve insulation; the main support frame 211 and the connecting frame 212 can also be made of insulating material, and the insulating material can be plastic or ceramic material, etc.

[0045] Please see Figure 2 Furthermore, the main support frame 211 includes a first support rod 2111 and a second support rod 2112. The first support rod 2111 and the second support rod 2112 are respectively fixedly connected to the side wall of the electrophoresis table 1, and the first support rod 2111 and the second support rod 2112 are respectively spaced apart along the length direction of the electrophoresis table 1.

[0046] The end of the first support rod 2111 away from the electrophoresis tank 10 is fixedly connected to the end of the second support rod 2112 away from the electrophoresis table 1. The first support rod 2111, the second support rod 2112 and the corresponding side wall of the electrophoresis table 1 form an isosceles triangle.

[0047] The end of the horizontal bar 2121 away from the vertical bar 2122 is fixedly connected to the connection between the first support bar 2111 and the second support bar 2112.

[0048] By setting the first support rod 2111 and the second support rod 2112, and forming an isosceles triangle between the first support rod 2111, the second support rod 2112 and the corresponding side wall of the electrophoresis tank 10, the stability of the fixing frame 21 is improved.

[0049] For further explanation, please refer to Figure 2 The main support frame 211 also includes two first fixing seats 2113. The two first fixing seats 2113 are respectively arranged corresponding to the first support rod 2111 and the second support rod 2112. The lower ends of the two first fixing seats 2113 are respectively fixedly connected to the side wall of the electrophoresis table 1, and the upper end surfaces of the two first fixing seats 2113 are respectively fixedly connected to the corresponding first support rod 2111 and the second support rod 2112.

[0050] Please see Figure 2 Furthermore, the main support frame 211 also includes a third support rod 2114 and a second fixed seat 2115;

[0051] The lower end of the second fixing seat 2115 is fixedly connected to the side wall of the electrophoresis table 1, and the upper end of the second fixing seat 2115 is fixedly connected to the third support rod 2114. The end of the third support rod 2114 away from the second fixing seat 2115 is fixedly connected to the connection between the first support rod 2111 and the second support rod 2112. The second fixing seat 2115 is located between the first support rod 2111 and the second support rod 2112. The third support rod 2114 is set perpendicular to the horizontal ground.

[0052] The second fixed base 2115 has a clearance through hole on the end face facing the rotating hanging plate 23. The end of the rotating shaft 22 away from the vertical rod 2122 passes through the shaft hole and the clearance through hole in sequence and is fixedly connected to the driving member 24. The rotating shaft 22 is rotatably connected to the second fixed base 2115.

[0053] By setting the third support rod 2114, and setting the third support rod 2114 perpendicular to the horizontal ground, the stability of the fixing frame 21 is further improved.

[0054] Meanwhile, by setting one end of the rotating shaft 22 away from the vertical rod 2122 to pass through the shaft hole and the clearance through hole in sequence and then be fixedly connected to the driving member 24, the second fixed seat 2115 can support the rotation of the rotating shaft 22, which helps to improve the stability of the rotating hanging plate 23 when it rotates.

[0055] Please see Figure 3 Furthermore, the connecting frame 212 also includes a bearing ring 2123, which includes an outer ring and an inner ring, and the outer ring and the inner ring are rotatably connected.

[0056] The vertical rod 2122 is fixedly connected to the outer ring, and the rotating shaft 22 is fixedly connected to the inner ring.

[0057] When the rotating shaft 22 rotates, it can drive the inner ring to rotate relative to the outer ring, while the outer ring remains stationary, thereby realizing the rotational connection between the rotating shaft 22 and the vertical rod 2122.

[0058] For further explanation, please refer to Figure 3 The rotating hanging plate 23 also includes a hollow sleeve 231, which is fitted into the shaft hole. The outer circumference of the sleeve 231 is fixedly connected to the inner circumference of the shaft hole. One end of the rotating shaft 22 away from the vertical rod 2122 passes into the sleeve 231 and is fixedly connected to the inner circumference of the sleeve 231.

[0059] Please see Figure 3 Furthermore, the driving component 24 includes a connecting rod 241 and a handle 242;

[0060] One end of the connecting rod 241 is fixedly connected to the end of the rotating shaft 22 away from the vertical rod 2122, and the other end of the connecting rod 241 is fixedly connected to the handle 242;

[0061] The connecting rod 241 is arranged perpendicularly to the rotating shaft 22, the handle 242 is arranged perpendicularly to the connecting rod 241, and the end of the handle 242 away from the connecting rod 241 extends horizontally in a direction away from the rotating shaft 22.

[0062] By configuring the drive component 24, which includes the connecting rod 241 and the handle 242, the experimenter can easily rotate the rotating hanging plate 23 by holding the handle 242. This allows each of the adhesive experimental steel plates to enter the electrophoresis tank 10 in sequence and come into contact with the electrophoresis solution as the rotating hanging plate 23 rotates (ensuring that each adhesive experimental steel plate is completely immersed in the electrophoresis solution for at least 10 seconds). Then, the plates leave the electrophoresis tank 10 as the rotating hanging plate 23 rotates, thus completing the electrophoresis operation. The operation is simple, convenient, and easy to implement.

[0063] Optionally, the driving component 24 can also be configured as a rotary motor. The output end of the driving component 24 is fixedly connected to the rotating shaft 22 to drive the rotating shaft 22 to rotate, thereby driving the rotating hanging plate 23 to rotate. This allows the steel plate for the adhesive experiment to enter the electrophoresis tank 10 and contact the electrophoresis solution in sequence as the rotating hanging plate 23 rotates, and then leave the electrophoresis tank 10 as the rotating hanging plate 23 rotates, thus completing the electrophoresis operation.

[0064] To further explain, the connecting rod 241 and the handle 242 can both be made of insulating materials, such as plastic or ceramic.

[0065] Please see Figure 4 and Figure 5 Furthermore, the longitudinal cross-section of the rotating hanging plate 23 is circular, and the plurality of hooks 25 are evenly distributed along the circumference of the rotating hanging plate 23.

[0066] For further explanation, please refer to Figure 4 The distance L1 between two adjacent hooks 25 is 5cm. It should be noted that the size of the steel plate used for the adhesive experiment is fixed, with a width of 2.5cm and a length of 10cm. The vertical distance between the first opening and the height of the electrophoretic liquid in the electrophoresis tank 10 is about 3cm (that is, when filling the electrophoresis tank 10 with electrophoretic liquid, the electrophoretic liquid is filled into the electrophoresis tank 10 until the vertical distance between the height of the electrophoretic liquid and the first opening is 3cm). When the rotating hanging plate 23 is stationary, the vertical distance L2 between the highest point of the rotating hanging plate 23 and the first opening is 20cm. The depth setting of the electrophoresis tank 10 needs to meet the following conditions: the steel plate used for the adhesive experiment on the hook 25 at the lowest end of the rotating hanging plate 23 can be completely immersed in the electrophoretic liquid, and the steel plate used for the adhesive experiment does not interfere with the bottom of the electrophoresis tank 10.

[0067] Please see Figure 1Furthermore, the electrophoresis table 1 includes a main body 11, a connecting platform 12, and four support legs 13;

[0068] The connecting platform 12 is fixedly connected to the left and right ends of the main body 11, and the bottom end surfaces of the two connecting platforms 12 are respectively fixedly connected to two support legs 13.

[0069] The electrophoresis tank 10 is located inside the body part 11, and the horizontal plane of the bottom end face of the body part 11 is higher than the horizontal plane of the bottom end face of the support leg 13.

[0070] By setting the connecting platform 12 and the four supporting feet 13, the main body 11 can be easily raised, making it convenient for experimental personnel to perform electrophoresis operations.

[0071] Please see Figure 2 and Figure 4 Furthermore, the main body 11 includes a prism portion 111 and a pyramid portion 112 connected sequentially from top to bottom;

[0072] The prism portion 111 has a first cavity 1111 inside, and the first opening is opened on the upper end face of the prism portion 111. The first opening and the first cavity 1111 are interconnected.

[0073] The pyramidal portion 112 has a second cavity 1121 inside, and the inner diameter of the pyramidal portion 112 gradually decreases from top to bottom. The bottom of the pyramidal portion 112 has a discharge port, and the discharge port is connected to the second cavity 1121.

[0074] The first cavity 1111 and the second cavity 1121 are interconnected to form the electrophoresis tank 10. During the rotation of the rotating hanging plate 23, a portion of the rotating hanging plate 23 located below the rotating shaft 22 is located inside the first cavity 1111.

[0075] The electrophoresis station 1 also includes a discharge valve 14, which is installed at the discharge port.

[0076] Specifically, the discharge valve 14 can be used to open or close the discharge port. When it is necessary to replace the electrophoresis solution in the electrophoresis tank 10, the discharge valve 14 is opened, and the electrophoresis solution in the electrophoresis tank 10 can be discharged from the discharge port.

[0077] By providing the pyramidal portion 112, and by having the inner diameter of the pyramidal portion 112 gradually decrease from top to bottom, it is easier to drain the electrophoretic solution from the electrophoresis tank 10.

[0078] To further explain, the vertical distance between the horizontal plane where the bottom of the first cavity 1111 is located and the horizontal plane where the discharge port is located is at least greater than 10cm (that is, at least greater than the length of one of the adhesive test steel plates). During the rotation of the rotating hanging plate 23, by making the part of the rotating hanging plate 23 located below the rotating shaft 22 located inside the first cavity 1111, it is ensured that the adhesive test steel plate located on the hook 25 at the bottom of the rotating hanging plate 23 will not touch the inner wall of the pyramidal part 112 when rotating with the rotating hanging plate 23.

[0079] Please see Figure 6 Furthermore, the electrophoresis apparatus for the steel plate used in the adhesive experiment also includes a power supply device 3, which includes a power supply body 31, a positive electrode wire 32 and a negative electrode wire 33. The power supply body 31 is provided with a positive output terminal 311 and a negative output terminal 312.

[0080] The electrophoresis stage 1 also includes a positive electrode rod 15 and a negative electrode rod 16, and the upper end face of the electrophoresis stage 1 is also provided with a positive electrode hole and a negative electrode hole that are connected to the electrophoresis tank 10.

[0081] The two ends of the positive electrode wire 32 are electrically connected to the positive electrode output terminal 311 and the positive electrode rod 15, respectively, and the two ends of the negative electrode wire 33 are electrically connected to the negative electrode output terminal 312 and the negative electrode rod 16, respectively.

[0082] The positive electrode rod 15, with one end away from the positive electrode wire 32, passes through the positive electrode hole and is inserted into the interior of the electrophoresis tank 10; the negative electrode rod 16, with one end away from the negative electrode wire 33, passes through the negative electrode hole and is inserted into the interior of the electrophoresis tank 10.

[0083] The power supply body 31, the positive electrode wire 32, the positive electrode rod 15, the negative electrode wire 33, the negative electrode rod 16, and the electrophoresis liquid in the electrophoresis tank 10 are electrically connected to each other to form a complete circuit.

[0084] Specifically, the positive electrode hole and the negative electrode hole are respectively opened on the upper end surface of the connecting platform 12 located at both ends of the main body 11. It can be understood that a portion of the two connecting platforms 12 are covered on the upper end of the main body 11 so that the positive electrode hole and the electrophoresis tank 10 can be connected, and the negative electrode hole and the electrophoresis tank 10 can be connected.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
