Description

Technical Field

[0001] The utility model relates to the technical field of coating testing devices, and specifically to a coating sample fixing device. Background Technique

[0002] During the process of coating sample preparation, due to the differences in the heights of sample preparation personnel and their sample preparation habits, the requirements for the height of the sample from the ground will vary. The height of the traditional sample placing platform is fixed and cannot meet the usage requirements of various personnel. If the height is too low, long-term stooping will cause a huge burden on the body of the sample preparation personnel and is not conducive to the physical health of the sample preparation personnel. If the height is too high, for the sample preparation personnel, they need to hold their arms high to adapt to the height of the sample, which undoubtedly increases the difficulty of sample preparation.

[0003] In addition, there are three traditional ways to fix the sample: 1. Punch holes near the top of the sample and complete spraying by hanging the sample; 2. Fix the sample on a plane with double-sided tape for spraying; 3. Use a magnet to hold the sample under the sample to complete spraying. After the spraying and sample preparation of the sample are completed, the sample with the coating is removed and placed in an oven for constant temperature drying. Obviously, for the traditional sample, it is necessary to frequently remove the sample and place it in the oven. This process is not only inefficient, but also during the process of frequently taking the sample, the operator is likely to touch the sprayed surface of the sample and contaminate the sample. Content of the Utility Model

[0004] The utility model aims to at least solve one of the technical problems in the related technologies to some extent: to provide a coating sample fixing device that can be adjusted in height, and after the coatings of multiple samples are sprayed, they can be directly transferred to the oven, reducing the accidental touch of the sprayed surface of the sample by humans.

[0005] To this end, an object of the utility model is to propose a coating sample fixing device, which includes a base and a sample table located above the base. An elevating mechanism for driving the sample table to rise and fall is provided between the base and the sample table. The sample table includes a sample base connected to the elevating mechanism, a sample placing plate placed on the front of the sample base, and a clamping mechanism installed on the sample base for clamping the sample placing plate.

[0006] The above technical solution has the following advantages or beneficial effects: First, the elevating mechanism can drive the sample table to rise or fall, so that it can be arbitrarily adjusted to the optimal height according to the height of the sample preparation personnel, making the sample preparation process of the sample preparation personnel comfortable. Second, after all the samples on the sample placing plate are sprayed with coatings, the clamping mechanism can be controlled to loosen the sample placing plate, so that the entire sample placing plate can be put into the oven together, reducing the problems of low efficiency and easy contamination of the sample caused by transporting the samples one by one.

[0007] According to an example of the present utility model, the back surface of the template base has a connecting portion, and the template base is movably connected to the lifting mechanism through this connecting portion, so that the inclination angle between the template base and the horizontal plane is adjustable.

[0008] According to an example of the present utility model, the lifting mechanism includes a telescopic rod, and both ends of the telescopic rod are respectively connected to the base and the connecting portion.

[0009] According to an example of the present utility model, the connecting portion is hinged to the upper end of the telescopic rod through a rotating shaft.

[0010] According to an example of the present utility model, the clamping mechanism includes at least two clamping arms symmetrically arranged along the width direction of the template base. The clamping arm includes a chuck, a vertical rod, and a cross rod. One end of the cross rod is connected to the template base through a first telescopic member, so that the position of the cross rod along the width direction of the template base is adjustable. The lower end of the vertical rod is fixed to the other end of the cross rod. The chuck is placed at the upper end of the vertical rod, and the chuck is connected to the vertical rod through a second telescopic member, so that the height of the chuck along the vertical direction is adjustable. Through the oppositely arranged clamping arms, when the template is placed in the clamping space between the two clamping arms, under the elastic force of the first telescopic member, the chucks on the two clamping arms can move relative to each other until the template is clamped. The second telescopic member can make the chuck stretch along the vertical direction, so that the chuck can well complete the clamping action for templates of different thicknesses.

[0011] According to an example of the present utility model, a baffle is provided on one side of the template base along the length direction, and the template to be placed abuts against the baffle. The baffle plays a role of limiting along the length direction to prevent the template from shifting along the length direction.

[0012] According to an example of the present utility model, the template to be placed has a plurality of installation positions distributed at intervals, and a fixator for fixing the template is provided on the installation position, and the fixator is detachably connected to the template to be placed.

[0013] According to an example of the present utility model, the fixator includes a carrier and a bolt located at the bottom of the carrier, and a magnetic sheet is provided at the top of the carrier. Through the magnetic sheet, some templates that can be adsorbed by magnetic materials can be adsorbed, which is convenient for fixing each template on the template to be placed.

[0014] According to an example of the present utility model, the fixator includes a carrier, a bolt located at the bottom of the carrier, and one or more elastic suction nozzles fixed to the top of the carrier. A negative pressure air passage is provided in the carrier, one end of the negative pressure air passage is communicated with each elastic suction nozzle, and the other end is communicated with an external negative pressure device. Through the elastic suction nozzles, the template can be adsorbed by negative pressure, so that each template on the template to be placed can be kept in a fixed state during the spraying process, and when the external negative pressure device is removed, the templates on the template to be placed can be conveniently removed from the template to be placed.

[0015] Additional aspects and advantages of the present utility model will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0029] During the development process of the coating, the coating is sprayed onto a sample plate and then sent into an oven for constant-temperature drying. This sample preparation process of the coating is a frequent and important link in coating research and development. And the selection of the existing sample plate materials and shapes is diversified according to different coatings. The material can be magnetic or non-magnetic; its shape can be a standard rectangle or various non-standard shapes such as triangles. In the prior art, the sample preparation process of this coating sample plate is completed on a workbench with a fixed height. However, there are differences in the individual heights of the sample preparation personnel. Taller personnel will have a certain degree of bending over to work, which is likely to cause lumbar occupational diseases. Shorter personnel need to raise their arms for a long time to perform sample preparation operations, which is likely to cause muscle strain. In addition, the existing sample plates need to be temporarily fixed before spraying. In the prior art, it is more common to hang the sample plates for spraying or adhere the sample plates to the work platform and then spray. No matter which method is adopted, it is necessary to remove each sprayed sample plate one by one and then transfer it to the oven. During this process, when removing the suspended or adhered sample plates, it may cause contamination and damage to the sprayed surface of the sample plates. In addition, the process of transferring the sample plates to the oven one by one is also likely to accidentally touch the sprayed surface of the sample plates, and the one-by-one transfer method has low efficiency.

[0030] Based on the technical problems existing in the coating sample preparation process of the above prior art, the coating sample plate fixing device according to the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1

[0032] The present utility model provides a coating sample plate fixing device. As shown in the figure, it includes a base 100 and a sample plate table 300 located above the base 100. An elevating mechanism 200 for driving the sample plate table 300 to lift is provided between the base 100 and the sample plate table 300. The elevating mechanism 200 is fixed on the base 100 and is used to drive the sample plate table 300 to lift in the height direction. Specifically, as Figures 1-4 shown, the sample plate table 300 includes a sample plate base 1 connected to the elevating mechanism 200, a sample plate placement 2 placed on the front of the sample plate base 1, and a clamping mechanism 3 installed on the sample plate base 1 for clamping the sample plate placement 2. In this embodiment, the elevating 200 device can be used to drive the sample plate table 300 to lift and can maintain the adjusted height position.

[0033] Embodiment 2

[0034] On the basis that the lifting mechanism 200 can drive the template base 1 to lift, a further improvement is that the back surface of the template base 1 in this embodiment has a connecting portion 4, and the template base 1 is movably connected to the lifting mechanism 200 through the connecting portion 4 so that the inclination angle between the template base 1 and the horizontal plane is adjustable. The movable connection between the connecting portion 4 and the lifting mechanism 200 means that the inclination angle of the template base 1 relative to the horizontal plane can be adjusted and can be maintained at the inclined position after being adjusted to the required position. By adjusting the angle of the template base 1, the template can also be inclined synchronously, which can be used to simulate on-site construction and examine the construction performance of the paint, such as observing the longitudinal flow condition of the paint and the leveling performance after the paint is sprayed.

[0035] Embodiment Three

[0036] Based on the improvement of the above embodiment, the lifting mechanism 200 includes a telescopic rod 5, and both ends of the telescopic rod 5 are connected to the base 100 and the connecting portion 4 respectively. The telescopic rod 5 is an existing commercially available product, such as a telescopic air rod or an electric push rod. In this embodiment, the function of the telescopic rod 5 is only the basic telescopic function, so the specific structure of the telescopic rod 5 will not be described in detail in this embodiment.

[0037] Embodiment Four

[0038] As Figures 2-4As shown, the clamping mechanism 3 includes at least two clamping arms symmetrically arranged along the width direction of the template base 1. Preferably, there are two clamping arms. The clamping arm includes a chuck 3.1, a vertical rod 3.2, and a cross rod 3.3. The cross rod 3.3 is placed along the width direction of the template base 1, and the vertical rod 3.2 is placed vertically. Both sides of the template base 1 along the width direction have slots for the ends of the cross rod 3.3 to be inserted. A first telescopic member 3.4 is provided in the slot. One end of the cross rod 3.3 extends into the slot and is fixedly connected to the first telescopic member 3.4, and is connected to the template base 1 through the first telescopic member 3.4. By the expansion and contraction of the first telescopic member 3.4, the position of the cross rod 3.3 along the width direction of the template base 1 is adjustable. The lower end of the vertical rod 3.2 is fixedly connected to the other end of the cross rod 3.3, and the chuck 3.1 is placed at the upper end of the vertical rod 3.2. The top of the vertical rod 3.2 has a slot for the connection end of the chuck 3.1 to extend into. A second telescopic member 3.5 is provided in the slot. The chuck 3.1 is connected to the vertical rod 3.2 through the second telescopic member 3.5, and the height of the chuck 3.1 along the vertical direction is adjustable by the expansion and contraction of the second telescopic member 3.5. In this embodiment, when the template placing plate 2 with different widths or different thicknesses is placed on the template base 1, the chucks 3.1 on the two clamping arms of the clamping mechanism 3 can firmly clamp the template placing plate 2. And when there are multiple templates on the template placing plate 2, after each template is sprayed with paint, the entire template placing plate 2 can be removed from the template table and sent into the oven by loosening the clamping mechanism 3, thereby reducing the process of removing templates one by one, and at the same time avoiding human hands contacting the templates and thus contaminating the sprayed surfaces of the templates.

[0039] Preferably, the first telescopic member 3.4 and the second telescopic member 3.5 are tension springs. Both ends of the tension spring have connection buckles for fixedly connecting with the end of the cross rod 3.3 extending into the slot and the bottom of the slot.

[0040] Embodiment Five

[0041] Based on the preference of the above-mentioned Embodiment Three, as Figure 2 and Figure 3 shown, a baffle 6 is provided on one side of the template base 1 along the length direction, and the template placing plate 2 abuts against the baffle 6. The baffle 6 is fixed to the template base 1, which is beneficial to reducing the offset or even slipping of the template placing plate 2 along the length direction when it is clamped by the clamping mechanism 3. The length direction mentioned in this embodiment refers to Figure 2 the up and down direction in

[0042] Embodiment Six

[0043] Improvements to the template placing board 2 in the above embodiments: There are multiple templates on the template placing board 2. Specifically, there are multiple spaced-apart mounting positions on the template placing board 2. Preferably, the above mounting positions are arranged in an array along the length and width directions of the template placing board 2. A fixator 7 for fixing the template is provided on the mounting position, and the fixator 7 is detachably connected to the template placing board 2.

[0044] As Figure 2 shown, the mounting position refers to multiple holes or slots arranged on the template placing board. The fixator 7 has mounting parts that match the holes or slots on the mounting position, thereby realizing the detachable connection between the fixator 7 and the template placing board 2. Preferably, the template placing board has threaded holes at the positions where each mounting position is located, and the bottom of the fixator 7 has connection bolts that can be threadedly connected to the threaded holes.

[0045] One of the preferred examples of the fixator 7: As Figures 5-6 shown, the fixator 7 includes a carrier 7.1, a connecting piece 7.2 located at the bottom of the carrier 7.1, and a magnetic sheet 7.3 fixed to the top of the carrier 7.1. Specifically, as Figure 5 shown, a cover plate is provided above the magnetic sheet 7.1, and the cover plate is fixed to the carrier 7.1 by locking screws, thereby fixing the magnetic sheet to the top of the carrier 7.1. The fixator 7 in this embodiment adsorbs the template 10 by means of magnetic attraction. Therefore, the template 10 made of magnetic material can be applicable to the fixator 7 in this embodiment, and the template 10 is preferably made of iron-based material. Or the magnetic sheet 7.3 is embedded in the mounting groove at the top of the carrier 7.1 by means of bonding. Preferably, the connecting piece 7.2 is a bolt.

[0046] Another preferred example of the fixator 7: As Figures 7-8 shown, the fixator 7 includes a carrier 7.4, a connecting piece 7.5 located at the bottom of the carrier 7.4, and one or more negative pressure suction ports located at the top of the carrier 7.4. A negative pressure air duct 7.7 is provided inside the carrier 7.4. One end of the negative pressure air duct 7.7 is communicated with each negative pressure suction port, and the other end is communicated with an external negative pressure device. The external negative pressure device is preferably a vacuum pump, and the suction pipe of the vacuum pump is communicated with the air nozzle on the outer side wall of the carrier 7.4 where the negative pressure air duct 7.7 is located. Thus, when the template 10 is placed flat on the upper end surface of the carrier 7.4, the template 10 is adsorbed on the carrier 7.4 by the pumping action of the negative pressure suction port. Preferably, the connecting piece 7.5 is a bolt.

[0047] Another preferred example of the fixator 7: As Figures 9-10As shown, the fixture 7 includes a carrier 7.4, a connecting member 7.5 located at the bottom of the carrier 7.4, and one or more elastic suction nozzles 7.6 fixed to the top of the carrier 7.4. A negative pressure air passage 7.7 is provided inside the carrier 7.4. One end of the negative pressure air passage 7.7 communicates with each elastic suction nozzle 7.6, and the other end communicates with an external negative pressure device. The external negative pressure device is preferably a vacuum pump, and the suction pipe of the vacuum pump communicates with a nozzle on the outer side wall of the carrier 7.4 where the negative pressure air passage 7.7 is located. Thus, when the template 10 is placed flat on the elastic suction nozzles 7.6 on the upper end surface of the carrier 7.4, the template 10 is adsorbed on the elastic suction nozzles 7.6 of the carrier 7.4 by the air suction action of the elastic suction nozzles 7.6. Preferably, the connecting member 7.5 is a bolt.

[0048] It should be understood that the above-mentioned threaded connection method between the fixture 7 and the template holder 2 has the advantages of quick disassembly and repeated use compared with the existing bonding methods, etc., but it does not exclude the use of bonding methods to realize the connection between the fixture 7 and the template holder 2.

[0049] Embodiment Seven

[0050] As Figure 1 shown, through the arrangement of the connecting portion 4, the template base 1 can swing vertically, thereby adjusting the inclination angle of the template base 1, which is beneficial for the sample preparation personnel to facilitate the sample preparation process. It can be used to simulate on-site construction and investigate the construction performance of the coating, such as observing the longitudinal flow condition of the coating and the leveling performance after the coating is sprayed. Based on the further improvement of the connecting portion 4 in the above-mentioned embodiment: the connecting portion 4 is arranged to be able to drive the template base 1 to rotate in the horizontal direction. Thus, the template base 1 can rotate and face any position in the circumferential direction, making the sample preparation process more convenient.

[0051] Embodiment Eight

[0052] Based on the improvement of the above-mentioned embodiment: As Figure 1 shown, the telescopic rod 5 includes an inner tube and an outer tube that can move relative to each other along the axial direction. The outer tube is sleeved outside the inner tube, and a locking screw for locking the inner tube and the outer tube is provided between the inner tube and the outer tube. The outer tube is sleeved outside the stabilizing ring and a plurality of brackets 8 arranged around the stabilizing ring 9, and the lower ends of the brackets 8 are connected to the base 100. Thus, the telescopic rod 5 is made more stable through the stabilizing ring 9 and the plurality of brackets 8.
