Description

Dustproof combination for linear modules

This creation is related to the dustproof structure, especially a dustproof combination for linear modules.

When the general linear module is used in a dusty environment, such as woodworking machinery, machine tools, etc., a dustproof belt is often added between the mobile platform and the casing to prevent foreign objects from entering the casing and less dust accumulation, to avoid screws. Unsmooth operation and increased wear between the nut and the nut reduce the working life. However, in a dusty environment, although the addition of a dust belt can effectively block most dust directly from entering the housing, but because the dust belt still has to cross the mobile platform, there is still a gap between the dust belt and the mobile platform. Design of dust entering the enclosure.

In this regard, there has been a new patent issued by the Republic of China No. M319110, which is a slide structure improvement. The technology used is to form a magnetic layer on the track and the slide, so that the steel strip is tightly adsorbed on the track and the slide. In addition, the cover body is fixed with a two reed system, which tightly presses the steel belt against the slide seat, so that the cover body completely covers the track, and prevents dust from entering the inside of the track. However, because the technology of this case needs to coat the sliding seat with a wear-resistant layer and magnetic components, the production cost is high and the gap between the dustproof belt and the mobile platform is not considered.

Furthermore, Japanese Patent No. 5465017 uses a sealing tape to bypass the platform through magnetic repulsion, and then uses a seal band guide portion (16d) to attach the sealing tape to the surface. Although the sealing performance is increased, the technology of this case needs to make the sealing tape adhere through the accessories, and the sealing tape needs to be additionally magnetized to increase the cost and process complexity, and the gap between the dustproof tape and the mobile platform is not considered.

The main purpose of this creation is to provide a dustproof combination for linear modules, which can effectively isolate external dust and achieve dustproof effects.

The reason is that according to a dustproof combination for a linear module provided in this creation, it is provided in a linear module, the linear module has a casing and a mobile platform is arranged in the casing, and the mobile platform protrudes from the casing The mobile platform is driven by a ball screw provided in the housing, and a dustproof belt is provided along the moving direction of the mobile platform. The dustproof belt cover is provided on the mobile platform.

The dust cover provided by this creation is set on the mobile platform, and the dust lip contacts the linear module housing and the dust belt, which can effectively isolate external dust and achieve the effect of dust prevention.

In addition, the dust lip surrounds the through opening, the third opening, and the fourth opening. Thereby, the dustproof belt crosses the mobile platform between the third opening and the fourth opening, and the dustproof lip isolates the external dust, further preventing the dust from entering the linear module through the gap between the dustproof belt and the mobile platform.

Furthermore, a guide plate is further included, which is connected to the first side wall and is located in the through opening. The guide plate has a guide surface connected to the first side wall and connected to the first opening edge, and the guide surface extends obliquely from bottom to top. With the guide plate, the dustproof belt can be guided smoothly across the mobile platform. In addition, the dust removal guide can also be leaned against the mobile platform.

In addition, it may further include a dust cover with an accommodating groove, the accommodating groove receives the dust removal guide block, and covers the penetrating opening, the first extension wing and the second extension wing. In this way, external dust is prevented from entering the dust removal guide block, and the dust removal effect is further enhanced. It is worth mentioning that the accommodating groove has a depth; the dust removal guide block has a thickness greater than the depth to ensure the dust-proof effect of the dust removal guide block. It should also be noted that, the preferred design method is that the thickness minus the depth is preferably 0.05 mm to 0.15 mm.

As shown in Figs. 1-5, a dustproof combination 10 for a linear module provided by a preferred embodiment of the present invention is provided for a mobile platform 91 of a linear module 90. The linear module 90 uses a motor 93 located in the housing 92 to drive a screw 94 to drive a nut 95 (this part is a common structure, not shown in the figure) that is pivotally connected to the mobile platform 91, so that the mobile platform 91 reciprocates. The aforementioned moving platform 91 is protruded from the casing 92 and a dustproof belt 96 covering the casing is provided for fixing components.

The dustproof assembly 10 includes a dust removal guide 11, a first extension wing 12, a second extension wing 13, and a dust lip 14.

The dust removal guide block 11 has a first side wall 111, a second side wall 112, a third side wall 113, and a fourth side wall 114 connected in this order. The first sidewall 111 is connected to the second sidewall 112, the second sidewall 112 is connected to the third sidewall 113, the third sidewall 113 is connected to the fourth sidewall 114, and the fourth sidewall 114 is connected to the first sidewall 111.

In addition, a through hole 115 is defined by the first side wall 111, the second side wall 112, the third side wall 113 and the fourth side wall 114. The penetrating opening 115 is provided when the dust removal guide 115 is sleeved on the mobile platform 91, and the mobile platform 91 can penetrate the dust removal guide 11.

The first side wall 111 has a first opening 111a. The first opening 111 a is configured for the dustproof belt 96 to pass through to move the moving platform 91.

The third side wall 113 has a second opening 113a. The second opening 113 a is used for the dustproof belt 96 to pass through the moving platform 91.

The first extending wing 12 is connected to the first sidewall 111.

The receiving groove 161 receives the dust removal guide block 11 and covers the penetration opening 115, the first extension wing 12 and the second extension wing 13. In this way, external dust is prevented from entering the dust removal guide block 11, and the dust removal effect is further enhanced. It is worth mentioning that the receiving groove 161 has a depth h. The dust removal guide block has a thickness H, and the thickness H is greater than the depth h to ensure the dustproof effect of the dust removal guide block 11. It should also be noted that the preferred design method is that the thickness H minus the depth h is preferably 0.05 mm to 0.15 mm. In this way, the dust cover 16 can first remove some external dust without affecting the operation of the mobile platform 91, and then the dust removal guide 11 can effectively isolate external dust to achieve the effect of dust prevention.

Based on the above description, the dustproof combination 10 provided by this creation can set the dust removal guide 11 on the mobile platform 91 and then fix the dust cover 16 to the mobile platform 91 and cover the dust removal guide 11. In this way, when the linear module 90 operates, the mobile platform 91 will also cause the dustproof assembly 10 to reciprocate on the casing 92 and the dustproof belt 96 while generating the reciprocating motion. In addition to the dust cover 16 removing dust to the housing 92 during the movement, the dust removal guide 11 in the dust cover 16 also removes dust to the outside of the housing 92, thereby improving the dust removal effect.
