Description

Technical Field

[0001] The invention belongs to the technical field of glass substrates, and in particular relates to a contact-type dust-free edge grinding mechanism for a glass substrate. Background Art

[0002] Glass substrates are one of the key basic materials in the flat panel display industry. During production and processing, the edges of glass substrates need to be ground. However, a large amount of dust is generated during the actual production process. Existing grinding mechanisms find it difficult to completely collect the grinding dust. On the other hand, existing grinding structures do not have the performance of flexible structures. That is, when the grinding head contacts the glass substrate, the existing ones are mostly in direct contact. This leads to excessive contact or pressure between the grinding head and the glass substrate during actual processing, which can easily lead to excessive grinding of the glass substrate. Therefore, there is an urgent need to solve the above problem. Summary of the Invention

[0003] In order to solve the problems raised in the above background technology, the present invention provides a glass substrate contact-type dust-free edge grinding mechanism, which has the characteristic of conveniently grinding the edge of the glass substrate.

[0006] The upper dust hood assembly includes an upper dust hood, an upper dust pipe and a first fixed plate are provided on the upper dust hood, a first sliding vertical rod is fixedly provided at one end of the first fixed plate, a first vertical groove is provided on the first sliding vertical rod, and a second tooth is provided in the first vertical groove.

[0007] Preferably, the lower dust hood assembly includes a lower dust hood, a lower dust hood is provided with a lower dust pipe and a second fixed plate, a second sliding vertical rod is fixedly provided at one end of the second fixed plate, a second vertical groove is provided on the second sliding vertical rod, and a third tooth is provided in the second vertical groove.

[0008] Preferably, the resisting and pushing sliding arm slides through the arm slide groove and the fixed frame platform, the limit block is located behind the fixed frame platform, the pushing buffer spring is located in front of the fixed frame platform, and the two ends of the pushing buffer spring respectively resist against the U-shaped support frame and the fixed frame platform, and through the pushing of the pushing buffer spring, the edge grinding wheel on the U-shaped support frame is in a forward resisting structure.

[0009] Preferably, the resisting and pushing sliding arm moves back and forth on the fixed frame platform, and the first geared wheel engages with the first teeth on the resisting and pushing sliding arm. When the resisting and pushing sliding arm moves backward, the first geared wheel forms a counterclockwise rotation structure, and the first geared wheel and the second geared wheel are coaxially arranged.

[0010] Preferably, the first sliding vertical rod slides up and down in the guide seat tube, the second teeth on the first sliding vertical rod engage with the inner wheel body of the second geared wheel, the second sliding vertical rod slides up and down in the guide seat tube, and the third teeth on the second sliding vertical rod engage with the outer wheel body of the second geared wheel.

[0011] Preferably, through the engagement between the second geared wheel and the third and second teeth, the second sliding vertical rod and the first sliding vertical rod form a synchronous approaching or moving away action structure on the glass substrate edge grinding and polishing assembly, and a gap for the transmission of the glass substrate is formed between the upper dust suction cover and the lower dust suction cover.

[0012] Preferably, in the initial state, the pushing of the pushing buffer spring causes the pushing sliding arm to slide forward on the fixed frame, and the second gear wheel drives the third tooth and the second tooth to cooperate with each other synchronously, so that the transmission gap between the lower dust cover and the upper dust cover is the maximum gap for facilitating the insertion of the glass substrate.

[0013] Preferably, through the buffering and tightening of the pushing buffer spring, a flexible contact edge grinding structure is formed between the edge grinding wheel and the glass substrate, and the limit block is located behind the fixed frame. Through the limitation of the limit block, the forward movement distance of the pushing sliding arm is limited to form a limited structure.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: when the present invention is in use, the upper dust suction cover assembly and the lower dust suction cover assembly form a fully surrounded grinding dust suction structure at the end of the glass substrate edge grinding and grinding assembly, and the dust suction pipes on the upper dust suction cover assembly and the lower dust suction cover assembly are connected to the external negative pressure dust suction device. In actual use, the pushing sliding arm slides through the arm slide groove and the fixed frame table through the pushing of the pushing buffer spring, and the edge grinding wheel on the U-shaped support frame is in a forward-collision structure. At the same time, through the setting of the pushing buffer spring, a flexible structure of the edge grinding wheel can be formed when the edge grinding wheel contacts the glass substrate. Through the setting of this structure, the direct hard structure between the edge grinding wheel and the glass substrate is avoided, and the glass substrate is avoided from being damaged due to the large contact pressure. At the same time, the first sliding vertical rod slides up and down in the guide seat tube, the second teeth on the first sliding vertical rod are meshed with the inner wheel body of the second geared wheel, and the second sliding vertical rod is in the guide seat tube. When the glass substrate is moved upward and downward, the third tooth on the second sliding vertical rod is engaged with the outer wheel body of the second geared wheel, and a gap for transmitting the glass substrate is formed between the upper dust cover and the lower dust cover. In the initial state, the pushing of the pushing buffer spring pushes the pushing sliding arm rod to slide forward on the fixed frame table, and the synchronous gearing cooperation of the third tooth and the second tooth is driven by the second geared wheel. The transmission gap between the lower dust cover and the upper dust cover is the maximum gap for facilitating the insertion of the glass substrate. In this way, it is convenient to transmit and interweave the glass substrate in the initial state. When the edge grinding starts, the glass substrate has a backward pushing force on the glass substrate edge grinding assembly. At this time, the gap between the lower dust cover and the upper dust cover is reduced by the synchronous gearing cooperation of the third tooth and the second tooth driven by the second geared wheel. The lower dust cover and the upper dust cover gradually approach the glass substrate. Only by this approaching way of contact can the dust suction effect of the upper dust cover assembly and the lower dust cover assembly be effectively guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

In the initial state, the pushing buffer spring 105 pushes the pushing sliding arm 101 to slide forward on the fixed frame 108, and the second gear wheel 113 drives the third gear 306 and the second gear 206 to synchronize the gearing. The transmission gap between the lower dust cover 301 and the upper dust cover 201 is the maximum gap for facilitating the insertion of the glass substrate.

[0027] The working principle and use process of the present invention: When the present invention is used, the upper dust collection cover assembly 200 and the lower dust collection cover assembly 300 form a fully enclosed grinding dust collection structure at the end of the glass substrate edge grinding assembly 100. The dust collection pipes on the upper dust collection cover assembly 200 and the lower dust collection cover assembly 300 are connected to the external negative pressure dust collection device. When actually used, the sliding arm 101 slides through the arm slide groove 116 and the fixed frame 108. The edge grinding wheel 102 on the U-shaped support frame 104 is in a forward-pushing position through the pushing of the pushing buffer spring 105. The structure of contact, and at the same time, by setting the push buffer spring 105, when the edge grinding wheel 102 contacts the glass substrate, a flexible structure of edge grinding can be formed. By setting this structure, the direct hard structure of the edge grinding wheel 102 and the glass substrate is avoided, and the glass substrate is avoided from being damaged due to the large contact pressure. At the same time, the first sliding vertical rod 204 slides up and down in the guide seat tube 114, and the second teeth 206 on the first sliding vertical rod 204 are engaged with the inner wheel body of the second geared wheel 113, and the second sliding vertical rod 304 slides up and down in the guide seat tube 114. The third tooth 306 on the second sliding vertical rod 304 is meshed with the outer wheel body of the second gear wheel 113, and a gap for the transmission of the glass substrate is formed between the upper dust cover 201 and the lower dust cover 301. In the initial state, the pushing of the pushing buffer spring 105 pushes the pushing sliding arm 101 to slide forward on the fixed frame 108. The second gear wheel 113 drives the third tooth 306 and the second tooth 206 to synchronize the gearing. The transmission gap between the lower dust cover 301 and the upper dust cover 201 is the maximum gap for facilitating the insertion of the glass substrate. In this way, the transmission and interlacing of the glass substrate in the initial state is convenient. When the edge grinding begins, the glass substrate has a backward pushing force on the glass substrate edge grinding assembly 100. At this time, the second gear wheel 113 drives the third teeth 306 and the second teeth 206 to cooperate with each other in synchronous gearing, and the gap between the lower dust cover 301 and the upper dust cover 201 is reduced. The lower dust cover 301 and the upper dust cover 201 gradually approach the glass substrate. Only through this conflicting approach can the dust collection effect of the upper dust cover assembly 200 and the lower dust cover assembly 300 be effectively guaranteed.
