Specific embodiments

[0029] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0030] As Figure 1-2 shown, the present utility model provides a coating adhesion tester, including: a bottom plate 1, which is horizontally arranged, and a column 2 is fixedly installed on one side of the bottom plate 1, and a support plate 3 is fixedly installed at one end of the column 2 away from the bottom plate 1; a clamping mechanism, which includes a support part slidably installed on the bottom plate 1, a pressing part vertically slidably arranged on the support part, a driving part fixedly installed in the bottom plate 1, and a transmission part connected between the support part and the driving part, and a limiting member is arranged between the pressing part and the support part; and a scribing detection mechanism, which is arranged below the support plate 3 and above the support part.

[0031] Place the coated plate on the support part, then operate the pressing part to press and fix the coated plate, and fix the position of the pressing part through the limiting member. Subsequently, start the scribing detection mechanism to make its detection end abut against the coated plate, and then start the driving part to drive the support part to slide through the transmission part, so that the scribing detection mechanism detects the coated plate along the length direction thereof; the operation is simple and convenient, and the limiting member can ensure the firm pressing of the coated plate by the pressing part, thus ensuring the detection effect and improving the detection efficiency.

[0032] As Figure 1-7As shown, according to another embodiment of the present utility model, the coating adhesion tester is further optimized for its support part, pressing part, transmission part and driving part. A first chute 11 is opened in the upper part of the bottom plate 1. The support part includes a connecting block 41 slidably connected to the first chute 11, a base 4 slidably attached to the upper part of the bottom plate 1, and a placement plate 5 slidably arranged on the upper part of the base 4. The connecting block 41 is fixedly connected to the base 4. The sliding direction of the placement plate 5 is perpendicular to the opening direction of the first chute 11. A locking member is provided between the placement plate 5 and the base 4. The pressing part is vertically slidably arranged on the upper part of the placement plate 5. The transmission part is located in the first chute 11 and is movably connected to the connecting block 41. A part of the transmission part freely passes through the first chute 11 and is connected to the power output end of the driving part; and preferably, the placement plate 5 is of a U-shaped structure. The placement plate 5 straddles the base 4 and is slidably connected thereto. The locking member includes a bolt 52 threadedly installed through one of the vertical sections of the placement plate 5. One end of the bolt 52 is used to abut against the base 4, and the other end is coaxially fixedly installed with a knob 51; since the placement plate 5 slides perpendicular to the first chute 11, the position of the coating plate pressed on its upper part to be detected can be changed by sliding the placement plate 5, ensuring that different positions of the coating plate can be detected. Moreover, the fixed state of the position of the placement plate 5 can be changed by operating the knob 51 to control the bolt 52 to abut against or disengage from the base 4.

[0033] Two rows of a number of second chutes 54 arranged oppositely are opened on the placement plate 5. Each row of the second chutes 54 has two. The pressing part includes two pressing blocks 7 arranged oppositely. Connecting plates 71 are fixedly installed between the two ends of the two pressing blocks 7. A sliding column 72 is fixedly installed at the lower part of each end of each pressing block 7. The four sliding columns 72 are slidably connected to the four second chutes 54 in a one-to-one correspondence. There are four limiting members and they are arranged in a one-to-one correspondence between the four sliding columns 72 and the placement plate 5.

[0034] Two cavities 53 are oppositely opened in the placement plate 5. The two cavities 53 are arranged in a one-to-one correspondence close to the two rows of second chutes 54. Each cavity 53 is communicated with the corresponding two second chutes 54 through a limiting hole 55. The four limiting members are used to be snap-connected to the four limiting holes 55 in a one-to-one correspondence. A pressing member is provided between the inner and outer sides of each cavity 53. The pressing member is used to abut against the limiting members in the two limiting holes 55 to push them out of the limiting holes 55.

[0035] On one end side wall of each sliding column 72 away from the pressing block 7, a third sliding groove 73 is formed. The width of the notch of the third sliding groove 73 is smaller than the width of its groove bottom. The limiting member includes a limiting block 74 slidably penetrating between the inner and outer sides of the third sliding groove 73. One end of the limiting block 74 located in the third sliding groove 73 is fixedly installed with a baffle 75. The baffle 75 is slidably clamped with the inner wall of the third sliding groove 73. The baffle 75 is elastically connected to the groove bottom of the third sliding groove 73 through a second spring 76. The limiting block 74 is used to freely penetrate into the corresponding limiting hole 55 and abut against the pressing member.

[0036] On the inner wall of each cavity 53 facing the second sliding groove 54, an installation groove 56 is formed. The pressing member includes a pressing plate 61 slidably arranged in the corresponding cavity 53. The pressing plate 61 is elastically connected to the installation groove 56 through a first spring 63. In the middle of the side wall of the pressing plate 61 away from the second sliding groove 54, a pressing block 6 is fixedly installed. The pressing block 6 freely penetrates out of the cavity 53. At both ends of the side wall of the pressing plate 61 facing the second sliding groove 54, two top blocks 62 are fixedly installed. The two top blocks 62 respectively and freely penetrate through the two limiting holes 55 and abut against the corresponding limiting blocks 74.

[0037] When pressing the coating plate, press down the two pressing blocks 7, so that the four sliding columns 72 slide towards the bottom of the second sliding groove 54 until the limiting blocks 74 on each sliding column 72 slide to the position of the limiting holes 55. At this time, through the elastic action of the second spring 76, the limiting blocks 74 are pushed into the corresponding limiting holes 55 and abut against the top blocks 62. At this time, the two pressing blocks 7 tightly press the coating plate on the placement plate 5; when it is necessary to remove the coating plate, then press the two pressing blocks 6. The two pressing blocks 6 drive the corresponding pressing plates 61 to compress the first spring 63, so that the two top blocks 62 on each pressing plate 61 push the corresponding limiting blocks 74 out of the limiting holes 55. At the same time, the limiting blocks 74 slide into the third sliding groove 73 and compress the second spring 76. Then, pull up the two pressing blocks 7 to separate from the coating plate, and the coating plate can be removed.

[0038] The transmission part includes a screw rod 42 rotatably installed inside the first sliding groove 11 along the length direction of the first sliding groove 11. The screw rod 42 freely penetrates through the connecting block 41 and is threadedly connected thereto. One end of the screw rod 42 freely penetrates out of the first sliding groove 11 and is connected to the power output end of the driving part; the rotation of the screw rod 42 drives the connecting block 41 to slide along the first sliding groove 11.

[0039] The driving part includes a first motor 43 fixedly installed in the bottom plate 1. The power output shaft of the first motor 43 is coaxially and fixedly connected to the screw rod 42; the first motor 43 can rotate forward and backward.

[0040] As Figure 1-2As shown, according to another embodiment of the present utility model, the coating adhesion tester further optimizes the included scribing detection mechanism. The scribing detection mechanism includes an electric telescopic rod 8 vertically and fixedly installed on the upper part of the support plate 3, a fixed block 9 arranged below the support plate 3, a rotating disk 91 rotatably installed below the fixed block 9, a needle holder 92 eccentrically and fixedly installed on the lower end surface of the rotating disk 91, and a scribing needle 93 vertically and detachably installed on the needle holder 92. The telescopic end of the electric telescopic rod 8 freely passes through the support plate 3 and is fixedly connected to the fixed block 9. A second motor (not shown) is fixedly installed in the fixed block 9, and the power output shaft of the second motor (not shown) freely passes out of the fixed block 9 and is coaxially and fixedly connected to the rotating disk 91. The electric telescopic rod 8 can control whether the scribing needle 93 abuts against the coating plate, and the second motor drives the rotating disk 91 to rotate, driving the scribing needle 93 to rotate eccentrically to perform scribing detection on the coating plate. The scribing needle 93 can be connected to the needle holder 92 in a clamping, plugging, interference fit or other ways, as long as the purpose of detachable scribing needle 93 can be achieved.

[0041] The working principle of the present utility model is as follows: When the present utility model is in use, place the coating plate on the placing plate 5, then press down the two pressing blocks 7, so that the four sliding columns 72 all slide towards the bottom of the second sliding groove 54 until the limiting blocks 74 on each sliding column 72 slide to the limiting holes 55. At this time, through the elastic action of the second spring 76, the limiting blocks 74 are pushed into the corresponding limiting holes 55 and abut against the top blocks 62. At this time, the two pressing blocks 7 tightly press the coating plate on the placing plate 5. Subsequently, operate the knob 51 to loosen the bolt 52, slide the placing plate 5 to adjust the detection position of the coating plate. After the adjustment is completed, operate the knob 51 again to tighten the bolt 52 to fix the position of the placing plate 5. Then start the electric telescopic rod 8 to push the scribing needle 93 to abut against the coating plate, then stop the electric telescopic rod 8 and start the first motor 43 and the second motor (not shown) at the same time, so that the scribing needle 93 performs scribing detection along the length direction of the coating plate. After the detection is completed, stop the first motor 43 and the second motor (not shown), start the electric telescopic rod 8 to drive the scribing needle 93 to disengage from the coating plate, then press the two pressing blocks 6, and the two pressing blocks 6 drive the corresponding pressing plates 61 to compress the first spring 63, so that the two top blocks 62 on each pressing plate 61 push the corresponding limiting blocks 74 out of the limiting holes 55. At the same time, the limiting blocks 74 slide into the third sliding groove 73 and compress the second spring 76. Subsequently, pull up the two pressing blocks 7 to disengage from the coating plate, and then the coating plate can be taken off.
