Description

Technical Field

[0001] This invention relates to the field of lamp panel processing equipment technology, and particularly to a splitting machine. Background Technology

[0002] In the mass production of LED lighting products, a panelization process is typically used to improve production efficiency. This involves pre-cutting V-grooves on large-size LED substrates, then using a dicing machine to separate them along these grooves to obtain multiple independent small-size LED substrates. However, existing dicing machines face challenges in changeover processing when producing multiple batches of small-size LED substrates of various specifications. Specifically, when producing LED substrates of different sizes or specifications, operators often need to perform tedious manual adjustments and calibrations to the dicing machine's positioning fixtures, dicing blade height, and feed parameters. This changeover process is time-consuming and labor-intensive, limiting the flexibility of the production line and overall output efficiency, and failing to meet the demands of modern electronics manufacturing for rapid changeover. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a dicing machine that can be quickly changed.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a chipping machine, including a frame, a transmission assembly, a pressing assembly, a force sensor, a display screen assembly, a guide, and two support rollers. The transmission assembly includes a drive component, a synchronous belt, and a drive roller and a driven roller respectively rotatably mounted on the frame. The drive component is mounted on the frame and is connected to the drive roller to drive its rotation. The synchronous belt is fitted onto the drive roller and the driven roller and is tensioned. The support rollers are mounted on the frame and pass through the synchronous belt. The pressing assembly includes a pressure roller and two opposing supports, which are fixed to the machine. The frame has a lifting block and a lifting screw on the support. The lifting screw is rotatably connected to the lifting block and threadedly connected to the support to drive the lifting block to rise and fall. The two ends of the pressure roller are rotatably connected to two lifting blocks respectively. The pressure roller is located above the synchronous belt and is set in the area between two support rollers. A force sensor is used to detect the downward pressure of the pressure roller. The display screen assembly is electrically connected to the pressure sensor to display the downward pressure detected by the pressure sensor. The guide is detachably installed on the frame and located at the inlet end of the synchronous belt. The guide has multiple guide grooves arranged in a row along the conveying direction of the synchronous belt.

[0005] The beneficial effects of this invention are as follows: The sharding machine features a detachable guide at the synchronous belt inlet end of the frame, with a row of guide grooves along the synchronous belt conveying direction. This eliminates the need for operators to perform tedious manual disassembly and repeated calibration of complex positioning fixtures as required by existing technologies when changing substrates of different specifications. Operators only need to replace the guide with one matching the corresponding guide groove specification according to the substrate width requirements to quickly achieve precise guidance and positioning of substrates of different sizes. This simplifies the changeover process, shortens equipment debugging and downtime, and solves the problems of cumbersome and inefficient changeover processing in existing sharding machines, improving the flexibility and overall output efficiency of the production line. Simultaneously, with the adjustable downward pressure assembly consisting of a lifting screw and a lifting block, operators can easily fine-tune the height of the pressure roller relative to the support roller to adapt to substrates of different thicknesses. Combined with real-time monitoring and feedback of the downward pressure by a force sensor and display screen assembly, precise control of the sharding depth and processing consistency are ensured, further guaranteeing the sharding quality and yield rate after changing multiple product specifications.

[0015] Example 1 Embodiment 1 of the present invention is: a slicing machine, used to slice a large-sized lamp board substrate with V-grooves to obtain multiple small-sized lamp board substrates.

[0016] Please refer to Figures 1 to 3 The chipping machine includes a frame 1, a transmission assembly 2, a pressing assembly 3, a force sensor 4, a display screen assembly 8, a guide 6, and two support rollers 7. The transmission assembly 2 includes a drive component 21, a synchronous belt 22, and a drive roller shaft 23 and a driven roller shaft 24 rotatably mounted on the frame 1. The drive component 21 is mounted on the frame 1 and is connected to the drive roller shaft 23 to drive the drive roller shaft 23 to rotate. The drive component 21 can be a drive motor, etc. The synchronous belt 22 is fitted onto the drive roller shaft 23 and the driven roller shaft 24 and is tensioned. The support rollers 7 are mounted on the frame 1 and pass through the synchronous belt 22. That is, the support rollers 7 are located in the hollow area enclosed by the synchronous belt 22 and support the inner surface of the upper layer of the synchronous belt 22. Preferably, the support rollers 7 are rotatable relative to the support 32 to reduce friction loss. The pressing assembly 3 includes a pressure... The roller 31 and two opposing supports 32 are fixed on the frame 1. The supports 32 are equipped with lifting blocks 33 and lifting screws 34. The lifting screws 34 are rotatably connected to the lifting blocks 33 and threadedly connected to the supports 32. The lifting screws 34 are used to drive the lifting blocks 33 to rise and fall. The two ends of the pressure roller 31 are rotatably connected to the two lifting blocks 33 respectively. The pressure roller 31 is located above the synchronous belt 22 and is set in the area between the two support rollers 7. The force sensor 4 is used to detect the downward pressure of the pressure roller 31. The display screen assembly 8 is electrically connected to the pressure sensor to display the downward pressure detected by the pressure sensor. The guide 6 is detachably installed on the frame 1 and located at the inlet end of the synchronous belt 22. The guide 6 has a plurality of guide grooves 61 arranged in a row. The guide grooves 61 are arranged along the conveying direction of the synchronous belt 22.

[0017] In actual production, a large, elongated light panel substrate is placed into the guide groove 61. This large light panel substrate has a V-groove, the length of which is parallel to the axis of the pressure roller 31. Furthermore, each of the guide grooves 61 can simultaneously accommodate the large light panel substrate, allowing the pressure roller 31 to perform dicing operations on multiple large light panel substrates at the same time, thereby improving production efficiency.

[0018] In some embodiments, the pressing assembly 3 further includes a handwheel 35 fixedly connected to the lifting screw 34. The handwheel 35 makes it easier for the operator to adjust the height of the pressing assembly 3, and provides a good gripping point, facilitating precise rotational control of the lifting screw 34. This enables accurate fine-tuning of the pressing height and pressure of the pressure roller 31, improving the convenience and accuracy of equipment debugging.

[0019] The support 32 is provided with a lifting groove, and the lifting block 33 is provided with a lifting slider that cooperates with the lifting groove; and / or, the support 32 is provided with a lifting slider, and the lifting block 33 is provided with a lifting groove that cooperates with the lifting slider. The cooperation of the lifting groove and the lifting slider constitutes a guide and limiting mechanism, which can effectively limit the degree of freedom of movement of the lifting block 33, ensuring that the lifting block 33 strictly moves vertically and linearly under the drive of the lifting screw 34, preventing the lifting block 33 from deflecting or swaying, thereby ensuring the stability and levelness of the pressure roller 31 during the lifting process, and thus ensuring the uniformity of force during the splitting operation.

[0020] Preferably, the outer peripheral wall of the pressure roller 31 is a buffer layer. Utilizing the elastic deformation characteristics of the buffer material, the pressure roller 31 provides flexible contact when it contacts and presses down on the lamp board substrate. This not only avoids the rigid pressure roller 31 directly and rigidly squeezing the lamp board substrate, preventing indentations or damage to electronic components, but also absorbs the vibration generated during the splitting process to a certain extent, making the splitting process smoother and improving the product yield. Optionally, the buffer layer is made of rubber. Rubber is chosen as the material for the buffer layer because it has excellent elasticity, wear resistance, and a high coefficient of friction. On the one hand, the rubber layer provides adequate buffer protection to prevent damage to the lamp board substrate; on the other hand, the rubber provides sufficient friction when in contact with the lamp board substrate surface, working in conjunction with the transmission component 2 to drive the lamp board substrate forward stably, preventing slippage or displacement of the lamp board substrate during the splitting process and ensuring the accuracy of the splitting position.

[0021] In some embodiments, the force sensor 4 is connected between the lifting block 33 and the bracket 32. Connecting the force sensor 4 between the lifting block 33 and the bracket 32, so that the sensor is directly connected in series on the force application path, allows the force sensor 4 to directly sense and feedback the actual vertical load applied by the lifting block 33 to the pressure roller 31. This eliminates measurement errors that may be caused by other components in the mechanical transmission chain (such as thread friction), thereby ensuring that the downward pressure value displayed on the display assembly 8 truly and accurately reflects the actual force exerted by the pressure roller 31 on the lamp board substrate, providing a reliable basis for the precise setting of process parameters. The force sensor 4 can be an S-type force sensor, etc.

[0022] A protective cover 9 is provided on the support 32. The lifting block 33, support 32, and pressure roller 31 are all covered inside the protective cover 9. The display screen assembly 8 is located on the protective cover 9 and exposed outside the protective cover 9. By providing a protective cover 9 on the support 32 to enclose the moving parts such as the lifting block 33, support 32, and pressure roller 31, a safety barrier is constructed, effectively preventing operators from accidentally touching moving parts or getting foreign objects caught in the equipment during operation, thus improving the safety of equipment use. At the same time, placing the display screen assembly 8 on the protective cover 9 and exposing it allows operators to intuitively read the downward pressure data from a safe area, balancing safety and operational convenience.

[0023] In one embodiment, the guide 6 includes a fixing strip 62 and a plurality of guide strips 63 arranged in a row at intervals on the fixing strip 62. Both ends of the fixing strip 62 are detachably connected to the frame 1. The length direction of the fixing strip 62 is perpendicular to the length direction of the guide strips 63, and the length direction of the guide strips 63 is consistent with the conveying direction of the synchronous belt 22. A guide groove 61 is formed between two adjacent guide strips 63, and the bottom surface of the guide strip 63 is close to the synchronous belt 22. The guide 6 adopts a structure combining the fixing strip 62 and a plurality of spaced guide strips 63, naturally forming the guide groove 61 using the gaps between adjacent guide strips 63. This structural design is simple and ingenious, with low manufacturing costs. Simultaneously, the bottom surface of the guide strips 63 being close to the synchronous belt 22 can stably limit the lateral positioning of the lamp board substrate, effectively preventing the lamp board substrate from swaying or deviating before entering the dicing station, ensuring the straightness and alignment accuracy of the lamp board substrate entering the dicing area.

[0024] Optionally, the guide strip 63 is adjustable along the length of the fixed strip 62. Setting the guide strip 63 to be adjustable along the length of the fixed strip 62 breaks the limitation of the fixed-spacing guide groove 61. Operators can flexibly adjust the spacing between adjacent guide strips 63 according to the actual width of the light panel substrate to be processed, thereby changing the width of the guide groove 61. This improves the versatility of the guide component 6, enabling it to adapt to various substrates of different sizes, and further reduces the tooling change costs and time when changing products.

[0025] In some embodiments, the fixing strip 62 has an elongated groove along its length, and the guide strip 63 is fixed to the fixing strip 62 by screws passing through the elongated groove. By creating an elongated groove on the fixing strip 62 and locking it with screws, a simple and reliable locking adjustment mechanism is provided. The elongated groove defines the adjustment trajectory of the guide strip 63, while the screws provide locking force. This connection method makes the position adjustment of the guide strip 63 very convenient; it can be slidably adjusted by simply loosening the screws, and locked after adjustment. This ensures both the flexibility of adjustment and the stability of the guide strip 63's position during the delamination process, preventing changes in the guide spacing due to vibration.

[0026] The structural principle of this flaking machine is briefly described below: The staff replaces the corresponding guide component 6 as a whole, or adjusts the position of the guide strip 63 in the guide component 6 relative to the fixed strip 62 to change the width of the guide groove 61; then rotates the handwheel 35 and observes the downward pressure displayed on the display screen component 8 until the downward pressure value reaches the preset value, then stops rotating the handwheel 35 and performs the change of the split piece.

[0027] During the splitting process, when the large-size lamp board substrate is between the synchronous belt 22 and the pressure roller 31, the synchronous belt 22 will deform in a direction away from the pressure roller 31, and at the same time, the large-size lamp board substrate conveyed by the synchronous belt 22 will break at the V-groove, thus completing the splitting.

[0028] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
