Description

Technical Field

[0001] The utility model relates to the technical field of solder-resistant coated wire drawing material, in particular to a solder-resistant coated wire drawing material clamp. Background Art

[0002] Among the equipment for IC substrates, the solder mask coating machine is specially used to produce the appearance protective layer. Its board gripping mechanism mainly relies on the claw clamp to grip the board. The clamp design of the claw clamp is a serrated design. It provides a stronger gripping force for the clamping of the board.

[0003] In the prior art, although the serrated claw clamp can more stably grip the substrate, it is easy to cause friction between the substrate and the serrated claw clamp, causing the grinding debris to fall and adhere to the substrate, resulting in yield loss. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that although the serrated claw clamp can grip the substrate more stably, it is easy to produce friction between the substrate, causing the chips to fall and adhere to the substrate, resulting in yield loss, and to propose a solder-resistant coated wire pulling clamp.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A solder resist coated wire drawing clamp, comprising:

[0007] Coating section channel;

[0008] Hanging plates are fixedly installed on the coating section channel. There are four hanging plates. Clamping seats are fixedly installed at the bottom ends of the four hanging plates. The top side of the clamping seats is flat. Support plates are fixedly installed on both sides of the clamping seats.

[0009] The stabilizing component is arranged on the clamping seat and plays a stabilizing role.

[0010] Furthermore, the stabilizing assembly includes two rotating shafts, which are rotatably connected to the two support plates respectively, and one end of the two rotating shafts is fixedly connected to a fixing cylinder, and a clamping claw body is provided in the two fixing cylinders.

[0011] Furthermore, an annular groove is provided on one side surface of the two support plates, and an annular block is slidably connected in the two annular grooves. The annular block performs an annular motion in the annular groove and has a limiting function.

[0012] Furthermore, one side of the two annular blocks is fixedly connected with a connecting plate, and the two connecting plates are fixedly connected to the two fixing tubes respectively, and the connecting plates have a supporting function for the fixing tubes.

[0013] Furthermore, a notch is provided on the upper part of the outer wall of the two fixing tubes, and the two fixing tubes are threadedly connected with a fastening screw, which fits with the clamping jaw body and has a fastening effect on it.

[0014] Compared with the prior art, the advantages of the utility model are:

[0015] 1. This solution changes the existing clamping seat from a sawtooth shape to a flat shape, and attaches a scratch-proof and anti-skid patch on the flat surface, which can ensure uniform contact between the clamping seat and the substrate, and has less friction on the substrate surface, and reduces the probability of generating wear debris. Four clamping seats can provide a more balanced clamping force distribution compared to three, which helps to reduce the risk of substrate sliding and position deviation caused by vibration. The design of four clamping seats can more accurately control the clamping position and angle of the substrate. Through fine clamping control, the deformation or distortion of the substrate during the coating process can be reduced. Four clamping seats can more easily achieve uniform distribution and fine-tuning of the clamping force, and can flexibly adjust the size and distribution of the clamping force according to the characteristics of different substrates and coating requirements, so as to obtain the best coating effect;

[0016] 2. In this solution, when the clamp body rotates, the annular groove can be designed so that the fixed cylinder rotates to drive the connecting plate to rotate, and the connecting plate drives the annular block to make annular motion in the annular groove, thereby improving the support stability.

[0017] The utility model has a simple structure, the design of the clamping claw body is changed from a sawtooth shape to a flat shape, and an anti-scratch and anti-slip patch is attached to the flat surface, and the equipment clamp design is changed from three clamping seats to four clamping seats, which increases the stability of the board holding and is convenient for people to use.

DETAILED DESCRIPTION

[0023] The technical solution of this embodiment will be clearly and completely described below in conjunction with the drawings in this embodiment. Obviously, the described embodiment is only a part of this embodiment, rather than all of the embodiments.

[0024] Embodiment 1

[0025] Reference Figure 1-Figure 4 , a solder resist coated wire pulling clamp, comprising:

[0026] Coating section channel 1;

[0027] Hanging plates 2 are fixedly installed on the coating section channel 1. There are four hanging plates 2. Clamping seats 3 are fixedly installed at the bottom ends of the four hanging plates 2. The top side of the clamping seats 3 is a flat surface 4. Support plates 5 are fixedly installed on both sides of the clamping seats 3.

[0028] The stabilizing component is arranged on the clamping seat 3 to play a stabilizing role.

[0029] In this embodiment, the stabilizing assembly includes two rotating shafts 6, which are rotatably connected to the two support plates 5 respectively. One end of the two rotating shafts 6 is fixedly connected to a fixing cylinder 7, and the two fixing cylinders 7 are provided with a clamping claw body 8.

[0030] In this embodiment, an annular groove 9 is provided on one side surface of the two support plates 5, and an annular block 10 is slidably connected in the two annular grooves 9. The annular block 10 performs annular motion in the annular groove 9 and has a limiting function.

[0031] In this embodiment, a connecting plate 11 is fixedly connected to one side of each of the two annular blocks 10 . The two connecting plates 11 are fixedly connected to the two fixing tubes 7 respectively. The connecting plates 11 support the fixing tubes 7 .

[0032] In this embodiment, notches are provided on the upper sides of the outer walls of the two fixing tubes 7 , and fastening screws 12 are threadedly connected to the two fixing tubes 7 . The fastening screws 12 fit the clamping jaw body 8 and have a fastening function thereon.

[0033] The implementation principle of the solder-resistant coated wire pulling clamp of the embodiment of the present application is as follows: when the clamp body 8 and the clamp seat 3 grab and fix the substrate, the existing clamp seat 3 is changed from a serrated shape to a flat shape, and a scratch-proof and anti-skid patch is attached to the flat surface to ensure uniform contact between the clamp seat 3 and the substrate. The friction force on the surface of the substrate is small, and the probability of generating wear debris is reduced. Four clamp seats can provide a more balanced clamping force distribution than three, which helps to reduce the risk of substrate sliding and position deviation caused by vibration. The design of four clamp seats 3 can more accurately control the clamping position and angle of the substrate. Through precise clamping control, the substrate can be reduced. Deformation or twisting during the coating process, the four clamping seats 3 can more easily achieve uniform distribution and fine-tuning of the clamping force, and can flexibly adjust the size and distribution of the clamping force according to the characteristics of different substrates and coating requirements, so as to obtain the best coating effect. When the clamping jaw body 8 needs to be replaced or repaired, the clamping jaw body 8 can be removed from the notch on the fixed cylinder 7 by unscrewing the fastening screws 12, and the disassembly can be completed. When the clamping jaw body 8 rotates, the design of the annular groove 9 can make the fixed cylinder 7 rotate to drive the connecting plate 11 to rotate, and the connecting plate 11 drives the annular block 10 to make an annular motion in the annular groove 9, thereby improving the support stability.

[0034] Embodiment 2

[0035] The difference between this embodiment and the first embodiment is that: a cavity 13 is provided on the clamping jaw body 8, a spring 14 is provided in the cavity 13, a slide plate 15 is fixedly connected to the spring 14, the slide plate 15 is slidably connected to the cavity 13, a connecting rod 16 is fixedly connected to the slide plate 15, a hidden groove 17 is provided on the clamping jaw body 8, and a rubber protrusion 18 is fixedly connected to one end of the connecting rod 16. When the clamping jaw body 8 cooperates with the clamping seat 3 to grasp and fix the material, the rubber protrusion 18 is squeezed into the hidden groove 17 due to the squeezing of the material. The rubber protrusion 18 drives the slide plate 15 to move through the connecting rod 16 and compresses the spring 14. The squeezing of the rubber protrusion 18 and the material can increase the resistance to the substrate, improve the stability, and will not cause damage to the substrate. All structures in this application can be selected in terms of material and length according to actual usage. The accompanying drawings are all schematic structural diagrams, and the specific actual dimensions can be appropriately adjusted.

[0036] The above description is only a preferred specific implementation manner of this embodiment, but the protection scope of this embodiment is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and utility model concept of this embodiment within the technical scope disclosed in this embodiment, and they should be covered by the protection scope of this embodiment.
