[0029] Figure 2

[0030] ​​​The first clamp head 112 and the second clamp head 122 preferably adopt a convex structure, having a connecting part and a clamping part. The connecting part of the first clamp head 112 is fixedly connected with the upper end surface of the first clamp jaw body 111, and the connecting part of the second clamp head 122 is fixedly connected with the lower end surface of the second clamp jaw body 121, as shown in Figure 3 or Figure 4 . That is, the connecting parts of the first clamp head 112 and the second clamp head 122 are respectively located in the middle of the first clamp jaw body 111 and the second clamp jaw body 121, which can further support and separate the first clamp jaw body 111 and the second clamp jaw body 121. The fixing mode between the clamp head and the clamp jaw body can have various forms, such as welding, gluing or bolt fastening, etc., which are not limited here. The clamping part of the clamp head extends away from the vertical plate 132, and the clamping part preferably adopts a vertically arranged plate structure. A plurality of first clamp heads 112 and a plurality of second clamp heads 122 are respectively arranged at intervals along the length direction of the vertical plate 132, and a plurality of first clamp heads 112 and a plurality of second clamp heads 122 are alternately arranged in the length direction of the vertical plate 132, as shown in Figures 2 to 4 . That is, one first clamp head 112 corresponds to one second clamp head 122, and a clamp jaw structure is formed between the first clamp head 112 and the corresponding second clamp head 122. Further, protective members 14 are respectively arranged on the opposite sides of the first clamp head 112 and the corresponding second clamp head 122, which preferably adopt a protective pad structure made of soft material such as silica gel, which is soft and non-toxic and odorless, and can prevent the clamp head from damaging the surface of the product 5 when clamping the product 5, effectively protecting the product 5.

[0031] In further embodiments, a plurality of first clamp heads 112 and a plurality of second clamp heads 122 are arranged in a staggered manner with different sizes, that is, the first clamp head 112 includes a plurality of first long clamp heads and a plurality of first short clamp heads, and the second clamp head 122 includes a plurality of second long clamp heads and a plurality of second short clamp heads, wherein the length of the short clamp head is less than the length of the long clamp head, and the first long clamp head corresponds to the second long clamp head one by one, and the first short clamp head corresponds to the second short clamp head one by one, as shown in Figures 2 to 4 . In this way, the product 5 can be arranged in a staggered manner when hanging, and the product 5 can be clamped in a staggered manner, which can clamp more products 5, and can effectively prevent the products 5 from colliding or winding together, further improving the coating effect.

[0032] As shown in Figures 2 to 4As shown, the figure schematically shows a clamping driving mode, that is, the clamping driving component 2 preferably adopts a clamping jaw cylinder. The clamping driving component 2 is fixedly arranged at the fixed part 1311 of the bottom plate 131, and is located at the same side of the clamping jaw on the bottom plate 131. A strip-shaped guide through hole is formed at the position corresponding to the first clamping jaw body 111 and the second clamping jaw body 121 of the vertical plate 132 respectively, and the length direction of the strip-shaped guide through hole is consistent with the length direction of the vertical plate 132. One connecting rod 21 is arranged in the strip-shaped guide through hole, so that the two ends of one connecting rod 21 are respectively connected with the first clamping jaw body 111 and one clamping jaw of the clamping jaw cylinder, and the two ends of the other connecting rod 21 are respectively connected with the second clamping jaw body 121 and the other clamping jaw of the clamping jaw cylinder. In this way, under the linkage of the connecting rod 21, when the clamping jaw cylinder works to open and close the two clamping jaws, it drives the first clamping jaw body 111 and the second clamping jaw body 121 to move in the length direction of the vertical plate 132, that is, drives the first clamping jaw 11 and the second clamping jaw 12 to move between the respective opening position and the clamping position. As shown in the figure, Figure 3 As shown, the first chuck 112 and the corresponding second chuck 122 have a certain interval. As shown in the figure, Figure 4 As shown, the first chuck 112 and the corresponding second chuck 122 are close or close, so as to clamp the product 5 placed between the first chuck 112 and the second chuck 122. It should be noted that the driving mode of the first clamping jaw 11 and the second clamping jaw 12 is not limited to this, and the clamping driving component 2 is also not limited to the clamping jaw cylinder. In specific implementation, the product 5 to be coated can also be clamped by driving the first clamping jaw 11 or the second clamping jaw 12 to move.

[0033] The silk guiding driving component 3 drives the clamping component 1 to move along the length direction of the clamped product 5. Preferably, the silk guiding driving component 3 can adopt a sliding table cylinder, which is recorded as a first sliding table cylinder, which is vertically arranged, and the bottom plate 131 is fixed on the sliding table of the first sliding table cylinder, so that the sliding table can be driven to move by the first sliding table cylinder, thereby driving the clamping component 1 to move in the vertical direction.

[0034] In further embodiments, the coating auxiliary device further comprises a contraction driving component 4 which drives the clamping component 1 to move towards or away from the product 5 to be clamped. The contraction driving component 4 can be of various structures, for example, a slide cylinder, denoted as a second slide cylinder, can be used, which is horizontally placed, and the main body thereof is fixedly connected with the slide of the second slide cylinder, and the bottom plate 131 is fixed on the slide of the second slide cylinder, so that the clamping component 1 can be moved in the vertical direction and also in the horizontal direction.

[0035] Further, a plurality of strip-shaped through holes 133 can be arranged on the combing portion 1312 of the bottom plate 131, which extend along the extending direction of the first chuck 112 or the second chuck 122 and penetrate the end of the bottom plate 131, and each strip-shaped through hole 133 is located between each group of corresponding first chuck 112 and second chuck 122, as shown in Figure 2 In specific implementation, the strip-shaped through hole 133 can be used as a guide groove. Meanwhile, the opening of the strip-shaped through hole 133 can be designed to be flared, so that when the clamping component 1 moves towards the product 5 to be coated, the product 5 to be coated can smoothly enter between the corresponding first chuck 112 and second chuck 122.

[0036] Next, the working process of the coating auxiliary device of the present embodiment will be further described.

[0037] When coating the product 5, the combing driving component 3 drives the contraction driving component 4 to drive the clamping component 1 to move upwards to a specified position as the starting position of combing. Then the contraction driving component 4 drives the clamping component 1 to move in the direction of the product 5, and during the movement, the first clamping jaw 11 or the second clamping jaw 12 of the clamping component 1 is in the open position. Then under the guidance of the strip-shaped through hole 133, the product 5 will move to between the corresponding first chuck 112 and second chuck 122 and be located at the position of the corresponding protection piece 14. Then the combing driving component 3 drives the contraction driving component 4 to drive the clamping component 1 to move downwards at a constant speed to a specified position, such as a position close to the liquid pipe 6, and during the movement downwards, the clamping component 1 will straighten and smooth the bent product 5.

[0038] Then the combing driving component 3 drives the contraction driving component 4 to drive the clamping component 1 to move upwards by a certain distance, and then the clamping driving component 2 drives the first clamping jaw 11 or the second clamping jaw 12 to move to the clamping position to clamp the product 5. Then the liquid pipe 6 moves upwards by a certain distance to make the bottom end of the product 5 inserted into the liquid pipe 6 for immersion coating of the product 5.

[0039] After the clamping driving part 2 drives the first clamping jaw 11 or the second clamping jaw 12 to move to the open position, then the pulling driving part 3 drives the retracting driving part 4 to drive the clamping part 1 to move upward by a distance, the clamping driving part 2 drives the first clamping jaw 11 or the second clamping jaw 12 to clamp the product 5, and then the liquid pipe 6 moves upward by a set distance to further dip-coat the product 5. The operation is repeated until the part to be coated of the product 5 is completely dipped in the coating liquid, and the clamping part 1 is driven by the retracting driving part 4 to move back to the initial position away from the product 5. In this way, the product 5 is well protected from the influence of the buoyancy of the coating liquid during the coating process under the clamping of the clamping part 1.

[0041] (1) The coating auxiliary device is provided with a clamping part which can move along the length direction of the product before coating, so as to straighten and smooth the product;

[0042] (2) The coating auxiliary device can ensure that the straightened and smoothed product can be smoothly dipped into the liquid pipe for coating during the coating process, so as to overcome the influence of the buoyancy of the coating liquid in the liquid pipe on the product;
