Description

Technical Field

[0001] This utility model relates to the field of glass shattering heating technology, specifically a contact heating mechanism for glass shattering. Background Technology

[0002] Glass cleaving refers to the process of creating predetermined cracks in glass during the cutting of a glass substrate using physical or chemical methods, and then separating it into multiple pieces by external force. This process is crucial in applications such as liquid crystal displays and other glass substrates. When laser cutting is used, the cut portions need to be cleaved and separated, requiring an auxiliary step of heating the glass.

[0003] Currently, quartz resistance wire (tube) heating is often used in the glass heating process. This method heats the glass through air conduction, resulting in low heating efficiency, long heating time, and high energy consumption. This increases the cost of glass heat treatment and reduces production efficiency. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a contact heating mechanism for glass sharding, comprising a fixed base, a support base, and a heat-conducting plate. PTC ceramic heating elements are attached to the top of the upper heat-conducting plate and the bottom of the lower heat-conducting plate. Grooves are formed at the front and rear positions of the bottom of the upper heat-conducting plate and the front and rear positions of the top of the lower heat-conducting plate. Temperature sensors are installed in the grooves. Connecting plates are fixed to the left sides of both the upper and lower heat-conducting plates. A guide plate is fixed to the right side of the upper heat-conducting plate, and a base plate is fixed to the right side of the lower heat-conducting plate. A guide rod is fixed to the top of the base plate. A groove for the guide rod to pass through is formed in the guide plate, and a communicating slot is formed in the slot. A ball bearing is embedded in the slot. A limiting disc for positioning is fixed to the top of the guide rod, and a protective pad is fixed to the bottom of the limiting disc at the outer ring position of the guide rod.

[0006] As a further technical solution of this utility model, the cross-section of the groove in the guide plate is circular, and the grooves are distributed in a ring about the center of the groove.

[0007] As a further technical solution of this utility model, the grooves are symmetrically distributed about the central axis of the heat-conducting plate, and the top of the protective pad is bonded and fixed to the bottom of the limiting plate.

[0008] As a further technical solution of this utility model, a threaded rod is connected and installed in the support base, and a guide rail rod is fixed in the support base on the side of the threaded rod.

[0009] As a further technical solution of this utility model, a servo motor is installed on the top of the support base, and the servo motor is covered with a heat insulation cover for heat insulation. The output end of the servo motor is connected to the threaded rod via a coupling.

[0010] As a further technical solution of this utility model, the threaded rod and the guide rail rod are externally connected to a movable block, and the sides of the two connecting plates are fixed with connecting plates.

[0011] As a further technical solution of this utility model, the upper connecting plate is connected and fixed to the movable block by bolts, and the lower connecting plate is fixed to the side of the support base by bolts.

[0012] As a further technical solution of this utility model, the movable block has a threaded groove inside that is threaded to the threaded rod, and a guide groove for the guide rod to slide through is provided inside the movable block at the side of the threaded groove.

[0013] As a further technical solution of this utility model, the lower heat-conducting plate is equipped with a feeding roller for feeding material at the front and rear positions, and the bottom of the side connecting plate of the upper heat-conducting plate is equipped with a buffer assembly for buffering. The buffer assembly includes a telescopic sleeve rod, a buffer spring and a contact plate. The top of the telescopic sleeve rod is fixedly installed to the bottom of the connecting plate, and the bottom of the telescopic sleeve rod is connected to the contact plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the contact heating mechanism for glass cleavers not only reduces power loss, but also improves the movement guidance and adjustment capabilities of the heating mechanism.

[0015] (1) By using two heat-conducting plates to clamp the glass, and attaching PTC ceramic heating elements to the heat-conducting plates, a groove is opened in the heat-conducting plates, and a temperature sensor is installed in the groove for temperature monitoring. In this way, the glass is heated by clamping it with two heat-conducting plates, and PTC ceramic heating elements are attached to the back of the heat-conducting plates. The heating is uniform, and the heating temperature is controlled between 80-90 degrees. This method has a good separation effect, smooth edges, low power loss, and is more energy-efficient than heating with quartz tubes.

[0016] (2) By fixing the bottom plate on the side of the lower heat-conducting plate and fixing the guide rod on the top of the bottom plate, the guide rod passes through the inside of the guide plate during the movement of the upper heat-conducting plate, so that the guide plate can be guided along the guide rod. The guiding process is protected by the groove and ball joint for rolling protection, while the upper limit plate serves the purpose of limiting and is protected by the protective pad for impact protection. This improves the moving guiding ability during the working process.

[0017] (3) The upper connecting plate is fixed to the movable block by bolts, and the lower connecting plate is fixed to the side of the support seat by bolts. After the servo motor is started, it drives the threaded rod to rotate.

[0026] The cross-section of the groove in the guide plate 10 is circular, and the grooves 21 are distributed in a ring about the center of the groove.

[0027] The grooves 8 are symmetrically distributed about the central axis of the heat-conducting plate 13. The top of the protective pad 20 is bonded and fixed to the bottom of the limiting plate 19. The heat-conducting plate 13 can be an iron plate, an aluminum plate or other metal materials.

[0028] A threaded rod 3 is connected and installed in the support base 2, and a guide rail 4 is fixed in the support base 2 on the side of the threaded rod 3.

[0029] A servo motor 5 is mounted on the top of the support base 2. The servo motor 5 is covered by a heat insulation cover 6 for heat insulation. The output end of the servo motor 5 is connected to the threaded rod 3 via a coupling.

[0030] The threaded rod 3 and the guide rail rod 4 are externally connected by a movable block 16, and the two connecting plates 17 are fixed with connecting plates 18 on their sides.

[0031] The upper connecting plate 18 is connected and fixed to the movable block 16 with bolts, and the lower connecting plate 18 is fixed to the side of the support base 2 with bolts.

[0032] The movable block 16 has a threaded groove 15 inside that is threaded to the threaded rod 3, and a guide groove 14 for the guide rod 4 to slide through is provided inside the movable block 16 at the side of the threaded groove 15.
