Description

Technical Field

[0001] This utility model relates to the field of thermoforming technology, and in particular to a PC board thermoforming machine. Background Technology

[0002] In modern electronics, electrical appliances, optics and other fields, PC sheets (polycarbonate sheets) are widely used due to their good mechanical properties, optical properties and heat resistance. Before being put into use, PC sheets often need to undergo thermoforming to meet different product design and usage requirements.

[0003] However, existing PC sheet thermoforming equipment has some shortcomings in practical applications.

[0004] 1) When traditional thermoforming equipment cuts and punches holes in PC sheets, the lack of effective buffering and stroke control devices can easily lead to excessive pressure of the cutting tool on the PC sheet, resulting in quality problems such as deformation and breakage, which affects the product qualification rate and performance.

[0005] 2) In the thermoforming process, the coordinated control of heating and cutting is not precise enough, resulting in unsatisfactory thermoforming effect of PC board. Burrs and unevenness are easy to appear at the cut, which increases the difficulty and cost of subsequent processing.

[0006] In addition, existing PC sheet thermoforming equipment has certain defects in the positioning and fixing of the sheet, making it difficult to guarantee the stability and accuracy of the PC sheet during processing, which affects the processing precision and efficiency. At the same time, the structural design of the equipment is not reasonable enough, and the coordination between various components is poor, resulting in the overall performance and reliability of the equipment needing to be improved. Utility Model Content

[0007] The purpose of this invention is to solve the problem that the coordinated control of heating and cutting in the existing technology is not precise enough, resulting in unsatisfactory thermoforming effect of PC board, and to propose a PC board thermoforming processing machine.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a PC board thermoforming machine, comprising: a first support, a second support fixedly connected to the top of the first support, and an extrusion mechanism fixedly connected to the outer wall of the second support; the extrusion mechanism includes an electric telescopic rod, a first mounting plate fixedly connected to the output end of the electric telescopic rod, a limit sleeve fixedly connected to the bottom of the electric telescopic rod, a second mounting plate fixedly connected to the bottom of the first mounting plate, a spring-loaded rod movably inserted inside the first and second mounting plates, a first spring sleeved on the outer wall of the spring-loaded rod, and a square cutter and a hole opener fixedly connected to the bottom of the second mounting plate.

[0009] Preferably, the bottom of the rebound rod is provided with a force-bearing mechanism; the force-bearing mechanism includes a fixed plate, the outer surface of the fixed plate is provided with a first through groove, a second through groove and a third cutting groove.

[0010] Preferably, a working platform is fixedly connected to the outer surface of the first bracket, a set of limiting posts are fixedly connected to the top of the working platform, a pressing plate is fixedly connected to the top of the working platform, and an opening is provided on the top of the pressing plate.

[0011] Preferably, a feeding baffle is fixedly connected to the top of the pressing plate, and a cutting placement position is provided inside the pressing plate.

[0012] Preferably, a pin is movably inserted inside the cutting placement position, and a heating module is fixedly connected to the bottom of the pin.

[0013] Preferably, a second spring is fixedly connected to the bottom of the heating module, and the bottom of the second spring is fixedly connected to the top of the working platform.

[0016] Preferably, a set of the first through slots and the feeding baffle cooperate with each other.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] 1. In this utility model, an electric telescopic rod, a limiting sleeve, a rebound rod, and a first spring are provided to control and protect the cutting and drilling processes. The limiting sleeve restricts the stroke of the electric telescopic rod to prevent the PC board from being squeezed. The rebound rod and the first spring absorb impact during cutting, preventing the PC board from deforming, improving the product qualification rate and the tool life. The cooperation between the heating module and the ejector pin locally heats and softens the PC board during cutting and drilling, reducing cutting resistance, resulting in a smoother cut, reducing burr generation, improving thermoforming effect and processing quality, and reducing the difficulty and cost of subsequent processing. The limiting post, feeding baffle, and openings and cutting placement positions on the working platform reliably position and fix the PC board, ensuring the stability and accuracy of the PC board during processing, and improving precision and efficiency.

[0019] 2. In this utility model, the structural design between components is reasonable, the connection is stable, and they can work together. For example, the fixed connection between the electric telescopic rod and the second bracket ensures the stability of the extrusion mechanism; the connection of components such as the rebound rod, the fixed plate, and the first spring enables the force-bearing mechanism to work in coordination with the extrusion mechanism, realizing the orderly progress of the entire thermoforming process and improving the overall performance and reliability of the equipment.

Detailed Implementation

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1: Please refer to... Figures 1-5 As shown, this utility model provides the following: Figure 1 As shown, the PC board thermoforming machine of this embodiment includes: a first support 1, a second support 11 fixedly connected to the top of the first support 1, and an extrusion mechanism 2 fixedly connected to the outer wall of the second support 11; the extrusion mechanism 2 includes an electric telescopic rod 201, a first mounting plate 202 fixedly connected to the output end of the electric telescopic rod 201, a limit sleeve 203 fixedly connected to the bottom of the electric telescopic rod 201, a second mounting plate 204 fixedly connected to the bottom of the first mounting plate 202, a spring rod 205 movably inserted inside the first mounting plate 202 and the second mounting plate 204, a first spring 206 sleeved on the outer wall of the spring rod 205, and a square cutter 207 and a hole opener 208 fixedly connected to the bottom of the second mounting plate 204.

[0029] The overall effect of Embodiment 1 is as follows: Providing power and installation foundation: The electric telescopic rod 201 serves as a power source, providing stable and controllable driving force for subsequent cutting and hole-making operations. The first mounting plate 202 and the second mounting plate 204 provide a mounting foundation for the square cutter 207 and the hole opener 208, ensuring the stability of the tools. Controlling stroke: The limiting sleeve 203 can limit the extension stroke of the electric telescopic rod 201, avoiding excessive compression of the PC board and ensuring that the cutting and hole-making depth is within a reasonable range, thereby improving processing accuracy. Buffer protection: The combination of the return rod 205 and the first spring 206 acts as a buffer. When the square cutter 207 and the hole opener 208 contact the PC board, the first spring 206 is compressed, absorbing some of the impact force and preventing damage to the tools or excessive deformation of the PC board due to excessive instantaneous pressure. Simultaneously, after cutting, the first spring 206 can reset the return rod 205, preparing it for the next processing.

[0030] Example 2: Please refer to... Figures 1-5 As shown, a force-bearing mechanism 3 is provided at the bottom of the rebound rod 205; the force-bearing mechanism 3 includes a fixed plate 301, a set of first through grooves 302 are formed on the outer surface of the fixed plate 301, a second through groove 303 and a third cutting groove 304 are formed on the outer surface of the fixed plate 301, a working platform 12 is fixedly connected to the outer surface of the first bracket 1, a set of limiting posts 13 are fixedly connected to the top of the working platform 12, a pressing plate 305 is fixedly connected to the top of the working platform 12, an opening 306 is formed on the top of the pressing plate 305, a feeding baffle 307 is fixedly connected to the top of the pressing plate 305, and a cutting placement position 308 is formed inside the pressing plate 305.

[0031] The overall effect of Embodiment 2 is as follows: Positioning and guidance: The working platform 12 provides a stable support surface for the processing of the PC board. The limiting post 13 can initially position the PC board to prevent it from moving horizontally during processing. The feeding baffle 307 further assists in positioning to ensure that the PC board is placed in the correct position. The first through groove 302 cooperates with the feeding baffle 307 so that the fixed plate 301 can avoid the feeding baffle 307 during descent, ensuring the normal operation of the structure. Clear cutting position: The opening 306 and cutting placement position 308 on the pressing plate 305 provide clear cutting and opening positions for the square cutter 207 and the hole opener 208, improving the accuracy of processing. At the same time, the second through groove 303 and the third cutting groove 304 also help the tool to complete the corresponding processing operations smoothly.

[0032] Example 3: Please refer to... Figures 1-5 As shown, a pin 42 is movably inserted inside the cutting placement position 308. A heating module 41 is fixedly connected to the bottom of the pin 42. A second spring 4 is fixedly connected to the bottom of the heating module 41. The bottom of the second spring 4 is fixedly connected to the top of the working platform 12. The outer surface of the electric telescopic rod 201 is fixedly connected to the outer surface of the second bracket 11. The bottom of a set of rebound rods 205 is fixedly connected to the top of the fixing plate 301. The two ends of a set of first springs 206 are fixedly connected to the top of the second mounting plate 204 and the top of the fixing plate 301, respectively. A set of first through grooves 302 cooperate with the feeding baffle 307.

[0033] The overall effect of embodiment 3 is as follows: thermoforming process: the heating module 41 can heat the ejector pin 42. During the cutting and hole-making process, the ejector pin 42 transfers heat to the PC board, causing the PC board to soften locally due to heat, making it easier to cut and hole, reducing cutting resistance, improving processing efficiency, and making the cut smoother and reducing burr generation. Elastic support and reset: the second spring 4 provides elastic support for the heating module 41 and the ejector pin 42. During the cutting process, the ejector pin 42 can extend and retract to a certain extent according to the thickness of the PC board and the processing conditions, avoiding damage to the PC board or the tool due to rigid contact. After the cutting is completed, the second spring 4 can automatically reset the ejector pin 42 to prepare for the next processing. Structural connection and collaborative work: the electric telescopic rod 201 is fixedly connected to the second bracket 11 to ensure the stability of the extrusion mechanism 2. The springback rod 205 is fixedly connected to the fixed plate 301. The first spring 206 connects the second mounting plate 204 and the fixed plate 301, so that the various components can work together to achieve the orderly progress of the entire processing process.

[0034] Working Principle: Preparation Stage: The PC board to be processed is placed on the work platform 12. The PC board is positioned using the limiting post 13 and the feeding baffle 307 to ensure it is in the correct processing position. At the same time, the heating module 41 is activated to bring the ejector pin 42 to a suitable temperature. Processing Stage: The electric telescopic rod 201 begins to extend, driving the first mounting plate 202 and the second mounting plate 204 to move downwards, thereby causing the square cutter 207 and the hole opener 208 to gradually approach the PC board. During this process, the return rod 205 descends along with it, the first spring 206 begins to be compressed, and the fixing plate 301 also descends accordingly. Its first through groove 302 avoids the feeding baffle 307. When the square cutter 207 and the hole opener... When the device 208 contacts the PC board, the PC board has been softened by the heating module 41, allowing the square cutter 207 to cut the PC board smoothly. The hole opener 208 then completes the hole opening operation. At the same time, the ejector pin 42, under the action of the second spring 4, extends and retracts appropriately according to the thickness of the PC board, providing auxiliary support and heating. In the reset phase: after processing, the electric telescopic rod 201 retracts, causing the first mounting plate 202 and the second mounting plate 204 to rise. The first spring 206 returns to its original state, causing the return rod 205 to reset the fixed plate 301. The second spring 4 also causes the ejector pin 42 and the heating module 41 to return to their initial positions. The entire PC board thermoforming machine is ready for the next processing.

[0035] The wiring diagrams of the electric telescopic rod 201 and the heating module 41 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the electric telescopic rod 201 and the heating module 41 will not be explained in detail.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
