Generally, the grinding head will be equipped with two sets of grinding wheels, which are arranged upper and lower. When the glass passes between the two sets of grinding wheels, the upper and lower edges of the glass are ground.

[0018] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0019] Reference Figure 1 An electrically controlled grinding head feeding detection mechanism includes an upper grinding wheel assembly, a lower grinding wheel assembly and a film removal assembly 5. The upper grinding wheel assembly, the lower grinding wheel assembly and the film removal assembly 5 are all arranged on a grinding head driving structure and driven as a whole by the grinding head driving structure. The upper grinding wheel assembly and the lower grinding wheel assembly are also provided with a grinding wheel driving mechanism, and the grinding wheel driving mechanism is used to drive the upper grinding wheel assembly and the lower grinding wheel assembly. The upper grinding wheel assembly includes an upper grinding wheel 3 and an upper grinding wheel motor, and the lower grinding wheel assembly includes a lower grinding wheel 4 and a lower grinding wheel motor. When grinding glass, the grinding head driving structure drives the grinding head to move as a whole to the processing position, and then the grinding wheel driving structure drives the upper grinding wheel assembly and the lower grinding wheel assembly to approach the processing position of the glass. After the grinding wheel reaches the processing position of the glass, the grinding wheel motor is started to drive the upper grinding wheel 3 and the lower grinding wheel 4 to grind. Since glass is relatively fragile, when the grinding wheel driving structure drives the upper grinding wheel assembly and the lower grinding wheel assembly to contact the glass, it is difficult to achieve accurate contact points for different glasses by setting a fixed feed amount to determine the contact point. When the contact position is determined by the reverse force generated when the grinding wheel contacts the glass, it is easy to cause a large impact on the glass, resulting in glass breakage. Therefore, a detection structure is also provided on the grinding wheel driving mechanism, and the detection structure is used to detect the driving state of the grinding wheel driving structure, and the detection structure is an electric induction mechanism. When the driving process of the grinding wheel driving structure is detected by electric induction detection, the grinding starting point of the grinding wheel on the glass can be determined in a timely and accurate manner, thereby avoiding the impact of the grinding wheel on the glass in the process of finding the contact point, and improving the stability of the processing process.

[0020] Reference Figure 2 , Figure 3 Specifically, the electric induction mechanism includes a forward induction 1 and an exit induction 2, and the forward induction 1 and the exit induction 2 are both triggered by the grinding wheel drive structure and control the feed of the upper grinding wheel assembly and the lower grinding wheel assembly. The forward induction 1 and the exit induction 2 are both arranged on the side of the induction connection section, and the positions of the forward induction 1 and the exit induction 2 are staggered. The grinding wheel drive mechanism includes a fixed plate 6, a sliding plate 7 and a feed drive, and the grinding wheel is arranged on the sliding plate 7; the sliding plate 7 is slidably connected to the fixed plate 6 through a sliding member, and the feed drive and the electric induction mechanism are both arranged on the fixed plate 6, and the position of the sliding plate 7 relative to the fixed plate 6 is adjusted. The fixed plate 6 is arranged on both sides of the top of the entire grinding head, so that the feed drive can be arranged on the two fixed plates 6, and it is convenient to be movably connected with the sliding plate 7 arranged at the bottom of the two fixed plates 6, so that the grinding wheel arranged on the sliding plate 7 can move with the sliding plate 7 and the feed drive, that is, the adjustment of the grinding wheel position is realized.

[0021] The feed drive includes a row rod motor 8 and a connecting member 9, and a motor rod that can move linearly on the motor is provided on the row rod motor 8. The electric induction mechanism controls the upper grinding wheel assembly and the lower grinding wheel assembly by induction of the feed drive. The forward induction 1 and the exit induction 2 are arranged on the side of the motor rod of the row rod motor 8. The forward induction 1 and the exit induction 2 arranged on the side are respectively arranged at different positions on the side of the motor rod of the row rod motor 8, and the motor rod is inductively detected at different positions of the motor rod. Further, the forward induction 1 and the exit induction 2 are respectively arranged corresponding to different extension positions of the motor rod of the row rod motor 8, and detect whether the motor rod is extended to the induction position. The forward induction 1 is used to sense whether the upper grinding wheel 3 or the lower grinding wheel 4 has reached the grinding position, and the exit induction 2 is used to sense whether the upper grinding wheel 3 or the lower grinding wheel 4 has left the grinding position. In this way, the start and stop of the linear motor are controlled by different electric inductions, so that the grinding wheel can accurately reach the grinding position, and the row rod motor 8 stops quickly without causing impact on the glass.

[0022] For the upper grinding wheel assembly and the lower grinding wheel assembly, one end of the connecting member 9 is fixedly connected to the motor rod of the rod motor 8, and the other end is rotatably connected to the sliding plate 7. When the rod motor 8 is in operation, the sliding plate 7 can be driven to move through the connecting member 9. The rod motor 8 drives the sliding plate 7 to move through the connecting member 9. The upper grinding wheel assembly and the lower grinding wheel assembly are arranged on the sliding plate 7 of the adjacent driving mechanism, and move with the sliding of the sliding plate 7. The sliding member includes a sliding rod and a sliding block. The sliding rod is arranged on the fixed plate 6, and the sliding plate 7 is arranged at the bottom of the sliding block. The sliding block is slidably arranged through a sliding shaft. A mounting plate is also arranged at the bottom of the sliding plate 7.
