Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laminating machine, in particular to a laminating machine roller structure and laminating machine. BACKGROUND

[0002] In the production process of circuit board, laminating process is the key process to ensure the production of high-performance printed circuit board. With the rapid development of technology, the requirements for circuit board production process are becoming more and more stringent, and the requirements for the durability and maintenance-free of each part of the laminating equipment are also becoming higher and higher.

[0003] Figure 1 It is a side view structure schematic diagram of the existing laminating machine roller structure. Figure 2 It is a partial enlarged view of Figure 1 .

[0004] When the laminating machine feeds, the tray carrying materials enters the gap between the pressing plates through the roller structure, and during laminating, the adjacent pressing plates are pressed together. With the rapid development of electronic and technology, the requirements for circuit board production process are becoming more and more stringent, and the requirements for the durability and maintenance-free of each part of the laminating machine are also becoming higher and higher. In order to reduce the friction and damage of the tray during the feeding process of the laminating machine, the stability of the roller mechanism is also higher. Figure 1 and Figure 2 As shown, the current roller structure mainly includes an assembled roller seat 1, a shaft, a locking screw 3 and a roller body 22, and the shaft is stopped by the locking screw 3. But as shown in Figure 2 , the locking screw 3 only has one point on the shaft, the shaft is not uniformly stressed, and there is a gap between the hole position on the shaft and the locking screw 3. During the working process of the roller structure, the locking screw 3 and the shaft will be worn and produce metal chips when they are stopped. After the wear, the locking screw 3 and the shaft may be deformed, and the shaft is difficult to exit the roller seat 1. And with the increasing demand for the load of the tray 4, the friction between the roller body 22 and the shaft increases when the roller body 22 rotates, and the wear between the locking screw 3 and the shaft during work is also gradually intensified, and the generated metal chips are easy to fall into the roller body 22 and the shaft, causing the roller body 22 to be stuck, and further causing the tray 4 to be worn. Therefore, this stopping method is no longer applicable. Content of the utility model

[0038] The present application provides a laminating machine roller structure and a laminating machine, which are used to prolong the service life of the laminating machine roller structure and make the installation and maintenance of the laminating machine roller structure more convenient.

[0039] The following will be described in detail in combination with the drawings and specific embodiments.

[0040] Figure 3 A side view structure schematic diagram of the laminating machine roller structure provided by the embodiments of the present application. Figure 4 For Figure 3 A partial enlarged view.

[0041] As Figure 3 And Figure 4As shown, the embodiment of the present application provides a kind of laminator roller structure 7 for carrying tray 4, laminator roller structure 7 includes: roller seat 1, one end of roller seat 1 has two clamping parts 10 opposite in first direction, clamping part 10 is provided with mounting hole 101 and adjusting groove 102, mounting hole 101 is through clamping part 10 along first direction, adjusting groove 102 is communicated with mounting hole 101 and is arranged through the outer surface of clamping part 10;Shaft body 21, shaft body 21 is inserted into two mounting holes 101;Roller body 22, roller body 22 is rotatably sleeved on shaft body 21, and is located between two clamping parts 10;Adjusting piece 5, adjusting piece 5 is used for adjusting the radial dimension of mounting hole 101 by adjusting groove 102.

[0042] Specific implementation, as Figure 3 And Figure 4 As shown, the radial dimension of mounting hole 101 is adjusted by adjusting piece 5, so that shaft body 21 can be arranged in mounting hole 101 of clamping part 10 of roller seat 1 and be held by mounting hole 101, so that the tray 4 carrying material can be conveyed into material by rotatable roller body 22, and shaft body 21 will not rotate with the rotation of roller body 22.

[0043] From the composition structure and specific implementation process of the above laminator roller structure 7, as Figure 3 And Figure 4As shown, in the laminating machine roller structure 7, one end of the roller seat 1 has two clamping parts 10, and the clamping parts 10 are provided with mounting holes 101 through which the shaft body 21 passes, so that the roller body 22 sleeved on the shaft body 21 can rotate around the shaft body 21 between the two clamping parts 10, thereby driving the tray 4 to move and realizing stable feeding. The opposite directions of the two clamping parts 10, the axial directions of the mounting holes 101 and the shaft body 21 are parallel, so that the shaft body 21 can be stably clamped by the clamping part 10, further improving the stability of the laminating machine roller structure 7 feeding. The clamping part 10 is also provided with an adjusting groove 102. Since the adjusting groove 102 is in communication with the mounting hole 101 and penetrates the outer surface of the clamping part 10, the adjusting groove 102 can be adjusted by the adjusting piece 5 to reduce the radial size of the mounting hole 101, so that the mounting hole 101 can tightly hold the shaft body 21, so that when the roller body 22 conveys the tray 4, the shaft body 21 will not be driven to rotate or shake due to the friction of the roller body 22 rotating, further improving the stability of the laminating machine roller structure 7 conveying feeding. As can be seen, the adjusting piece 5 can be used to adjust the adjusting groove 102 to tighten the mounting hole 101, so that the mounting hole 101 can tightly hold the shaft body 21, instead of the stop screw 3 to realize the rotation of the shaft body 21, avoiding the problem that the force surface of the shaft body 21 is too small and the pressure is too large when the rotation is stopped, which can better fix the shaft body 21, while increasing the force surface of the shaft body 21, so that the surface of the shaft body 21 is evenly stressed and is not easy to produce debris, avoiding the risk of the roller body 22 being stuck due to metal debris, prolonging the working life of the shaft body 21, thereby prolonging the working life of the laminating machine roller structure 7, while avoiding the deformation of the roller body 22 caused by wear, making the installation and maintenance of the laminating machine roller structure 7 more convenient.

[0044] In some examples, the adjusting groove 102 has two groove walls 1021, which are in communication with the mounting hole 101 and the outer surface of the clamping part 10 along the third direction B; the two groove walls 1021 are oppositely arranged along the second direction A, and the first direction, the second direction A and the third direction B are intersected two by two; the adjusting piece 5 is used to adjust the radial size of the mounting hole 101 by adjusting the spacing of the two groove walls 1021 in the second direction A.

[0045] Based on this, since the two groove walls 1021 of the adjusting groove 102 are both in communication with the mounting hole 101 and the outer surface of the clamping portion 10, the distance between the two groove walls 1021 in the second direction A can be adjusted by the adjusting piece 5, the radial size of the mounting hole 101 is adjusted, the mounting hole 101 can be tightened to tightly hold the shaft body 21, the stable rotation of the shaft body 21 is achieved, the force receiving surface of the shaft body 21 is increased, the surface of the shaft body 21 is uniformly stressed, and the risk of the roller body 22 being stuck by metal chips is avoided, the working life of the shaft body 21 and the laminating machine roller mechanism is prolonged, the installation and maintenance of the laminating machine roller mechanism are more convenient.

[0046] In some examples, the extension surface of the two groove walls 1021 can be any plane parallel to the axial direction of the mounting hole 101, so that the mounting hole 101 can be tightened from any position of the mounting hole 101, and the shaft body 21 can be uniformly stressed to achieve the tight rotation of the shaft body 21.

[0047] In some examples, the second direction A is perpendicular to the first direction, so that the distance between the two groove walls can be adjusted in a direction perpendicular to the axial direction of the mounting hole 101, so that the shaft is more uniformly stressed when the mounting hole 101 is tightened.

[0048] For example, the third direction B can be a direction perpendicular to the second direction A and the first direction.

[0049] Figure 3 And Figure 4 The second direction A and the third direction B shown in the above are only examples and are not specifically limited.

[0050] In some examples, the adjusting piece 5 can clamp the adjusting groove 102 from the outside of the clamping portion 10 to adjust the distance between the two groove walls 1021.

[0051] In some examples, as Figure 3 And Figure 4As shown, the adjusting member 5 comprises a fixing part 51, a first adjusting part and a second adjusting part (not shown in the figure) connected in sequence, the clamping part 10 is provided with an adjusting hole 103, the adjusting hole 103 comprises a first sub-hole 103a, a second sub-hole 103b and a third sub-hole 103c arranged along the second direction A, the axis centers of the first sub-hole 103a, the second sub-hole 103b and the third sub-hole 103c coincide; the first sub-hole 103a is used for accommodating at least part of the second adjusting part, the second sub-hole 103b is used for accommodating at least part of the first adjusting part, and the third sub-hole 103c is used for accommodating the fixing part 51; the first sub-hole 103a is connected with one of the groove walls 1021; one end of the second sub-hole 103b is connected with the other groove wall 1021, and the other end is connected in communication with one end of the third sub-hole 103c; the other end of the third sub-hole 103c away from the second sub-hole 103b is connected with the outer surface of the clamping part 10.

[0052] In specific implementation, the adjusting member 5 is inserted into the adjusting hole 103 with the second adjusting part aligned with the third sub-hole 103c, the second adjusting part sequentially passes through the third sub-hole 103c, the second sub-hole 103b and the interval between the two groove walls 1021, and is inserted into the first sub-hole 103a, so that at least part of the second adjusting part of the adjusting member 5 is located in the first sub-hole 103a, at least part of the first adjusting part is located in the second sub-hole 103b, and the fixing part 51 is located in the third sub-hole 103c.

[0053] Based on this, as shown in Figure 3 and Figure 4 The interior of the clamping part 10 can be provided with an adjusting hole 103 for accommodating the adjusting member 5, and the adjusting member 5 can adjust the interval of the two groove walls 1021 from the interior of the clamping part 10, so that the installation and maintenance of the shaft body 21 are more convenient, and the appearance is more beautiful. The adjusting hole 103 can be divided into three sub-holes, wherein the first sub-hole 103a and the second sub-hole 103b are respectively connected with the two groove walls 1021, and the third sub-hole 103c is connected with the second sub-hole 103b and the outer surface of the clamping part 10, so that the adjusting member 5 can be inserted into the adjusting hole 103 from the third sub-hole 103c and inserted into the second sub-hole 103b and the first sub-hole 103a. As can be seen, by cooperation of the adjusting member 5 and the adjusting hole 103, the interval of the two groove walls 1021 in the second direction A can be adjusted, and since the groove walls 1021 are connected with the mounting hole 101, the mounting hole 101 can be tightened from the radial direction of the mounting hole 101, so that the mounting hole 101 can tightly hold the shaft body 21, which can realize stable rotation stopping of the shaft body 21, make the surface of the shaft body 21 uniformly stressed, and avoid the risk of the roller body 22 being stuck by metal chips, thereby prolonging the working life of the shaft body 21 and the laminating machine roller mechanism, and making the installation and maintenance of the laminating machine roller mechanism more convenient.

[0054] In addition, in actual processing, the axes of the first sub-hole 103a, the second sub-hole 103b and the third sub-hole 103c can not be completely coincident, and can have a slight deviation.

[0055] In some examples, at least part of the surface of the adjusting member 5 has a first thread, and the hole wall of the first sub-hole 103a has a second thread that matches the first thread, so that a torque can be applied to the adjusting member 5, and the adjusting member 5 and the first sub-hole 103a are fastened together through the matching first thread and second thread. In the radial direction of the adjusting hole 103, the size of the opening through which the second sub-hole 103b and the third sub-hole 103c communicate is smaller than the size of the fixing part 51, so that the fixing part 51 located in the third sub-hole 103c can be clamped at the connection position of the second sub-hole 103b and the third sub-hole 103c, so that the two groove walls 1021 can be pulled closer in the second direction A while the mounting hole 101 tightly holds the shaft body 21, while a torque is applied to the adjusting member 5. In addition, one end of the adjusting member 5 is threadedly connected to the first sub-hole 103a, and the other end is clamped at the connection position of the second sub-hole 103b and the third sub-hole 103c, so that the adjusting member 5 and the clamping part 10 are easily disassembled, thereby making the installation and maintenance of the shaft body 21 and the laminating machine roller structure 7 more convenient.

[0056] For example, the torque applied to the adjusting member 5 should be greater than the friction between the roller body 22 and the shaft body 21, so as to achieve stable rotation of the shaft body 21. Further, the torque applied to the bolt can be adjusted according to the materials of the adjusting member 5 and the clamping part 10, which is not limited in the embodiments of the present application.

[0057] For example, the second direction A is perpendicular to the extension plane of the groove wall 1021, so that the adjusting member 5 can adjust the distance between the two groove walls 1021 in a direction perpendicular to the groove wall 1021, so that the shaft body 21 is more uniformly stressed.

[0058] Further, the extension plane of the two groove walls 1021 can be any plane parallel to the axial direction of the mounting hole 101, and the axial direction of the adjusting hole 103 can also be any direction perpendicular to the extension plane of the groove wall 1021, so that the mounting hole 101 can be tightened from any angle by the adjusting member 5, and the shaft body 21 can be uniformly stressed, thereby achieving tight rotation of the shaft body 21.

[0059] Further, in the two opposite clamping parts 10, the positions and structures of the mounting hole 101, the adjusting groove 102 and the adjusting hole 103 can all be the same, that is, the two opposite clamping parts 10 can be symmetrical about a plane perpendicular to the first direction, which is beneficial to reduce the processing difficulty.

[0060] For example, the adjusting member 5 can be a bolt, the fixing part 51 corresponds to the head of the bolt, and the end of the second adjusting part away from the fixing part 51 corresponds to the tail of the bolt.

[0061] In some examples, the first sub-hole 103a is a through-hole, one end of which is connected with one of the groove walls 1021, and the other end is connected with the outer surface of the clamping part 10; or, the first sub-hole 103a is a blind hole.

[0062] Based on this, the first sub-hole 103a can be a through-hole, in which case the two ends of the first sub-hole 103a are respectively connected with one of the groove walls 1021 and the outer surface of the clamping part 10, facilitating observation of the condition of the adjusting member 5 in the adjusting hole 103; the first sub-hole 103a can also be a blind hole, in which case one end of the first sub-hole 103a is connected with one of the groove walls 1021, and the other end is a blind end, which is conducive to ensuring the strength of the clamping part 10 and at the same time making the structure more beautiful. In addition, the first sub-hole 103a can be adjusted to be a through-hole or a blind hole according to the material of the clamping part 10.

[0063] In some examples, the hole wall of the second sub-hole 103b is a smooth hole wall. Based on this, when torque is applied to the bolt, the smooth second sub-hole 103b has less frictional resistance to the adjusting member 5, making it easier to adjust the distance between two adjacent groove walls 1021 by rotating the adjusting member 5.

[0064] As shown in Figure 4 , the radial dimension of the second sub-hole 103b can be greater than the maximum dimension of the first adjusting part in the diameter direction of the second sub-hole 103b. Further, from the perspective of actual processing, since the axes of the first sub-hole 103a, the second sub-hole 103b and the third sub-hole 103c of the adjusting hole 103 can not completely coincide, the radial dimension of the second sub-hole 103b and the maximum dimension of the first adjusting part in the diameter direction of the second sub-hole 103b can have a certain difference, so as to avoid the problem of difficult alignment.

[0065] As shown in Figure 3 and Figure 4 , the third sub-hole 103c can be connected with the outer surface of the clamping part 10 away from the tray 4 side, making the laminating machine roller structure 7 more beautiful.

[0066] As a possible implementation manner, the maximum distance between the two groove walls 1021 in the second direction A can be 2mm-3mm. Based on this, for the shaft body 21 with different radial dimensions, the maximum distance between the two groove walls 1021 of the clamping part 10 in the second direction A can be adjusted between 2mm-3mm. If the maximum distance between the two groove walls 1021 is too small, only the shaft body 21 with small radial dimension can be applied, and it is difficult to match the shaft body 21 with large radial dimension; if the maximum distance between the two groove walls 1021 is too large, the shaft body 21 cannot be firmly clamped even if the mounting hole 101 is tightened to the minimum, which affects the normal operation of the laminating machine roller structure 7.

[0067] For example, the maximum distance between the two groove walls 1021 in the second direction A can be 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm or 3mm, etc., which are only examples and are not specifically limited.

[0068] As a possible implementation manner, the adjustment range of the distance between the two groove walls 1021 in the second direction A can be 0-0.4mm. Based on this, in the second direction A, the distance between the two groove walls 1021 of the clamping part 10 can be adjusted by 0-0.4mm based on the maximum distance, so as to realize the good cooperation between the mounting hole 101 and the shaft body 21.

[0069] For example, the distance between the two groove walls 1021 in the second direction A can be adjusted by 0mm, 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm or 0.4mm based on the maximum distance, which are only examples and are not specifically limited.

[0070] In some examples, the radial dimension of the mounting hole 101 can also be designed according to the radial dimension of the shaft body 21, so as to realize the stable clamping and rotation-stopping of the shaft body 21 by the mounting hole 101.

[0071] In some examples, since the clamping part 10 will be deformed during the process of tightening the adjusting groove 102 by the adjusting part 5, the distance between the adjusting hole 103 on one side and the mounting hole 101 in the third direction B cannot be too small, and the distance between the adjusting hole 103 on the other side and the end face of the clamping part 10 in the third direction B also cannot be too small, so as to prevent the clamping part 10 from being broken. The specific distance can be adjusted according to the material of the clamping part 10, which is not limited in the embodiment of the application.

[0072] For example, the hardness of the material of the clamping part 10 can be greater than the hardness of the material of the shaft body 21, so as to realize the stable clamping and rotation-stopping of the shaft body 21.

[0073] As a possible implementation, the clamping part 10 has a structure 104 close to one side of the tray 4. Based on this, when the laminating machine roller structure 7 conveys the tray 4, the tray 4 will not directly contact the shell of the roller seat 1, realizing good contact between the tray 4 and the roller body 22.
