[0002] Circuit boards are an essential component of modern electronic products. During the production of circuit boards, in addition to printing circuits on the substrate, holes need to be drilled to facilitate the fixed installation of the circuit boards.

[0003] During the drilling process of circuit boards, the drill bit will produce circuit board debris. The debris is small and lightweight, and it will be blown around during the drilling process, making the production workshop dirty and messy. Workers are likely to inhale it during the process, which will affect their health. Utility Model Content

[0004] The purpose of this utility model is to provide a circuit board drilling device to solve the technical problems of existing drilling processes, such as debris flying around, causing the production workshop to be dirty and messy, and the flying debris being inhaled by workers, affecting their health.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0006] This utility model discloses a circuit board drilling device, including a workbench, wherein the workbench is provided with:

[0007] A driving mechanism, the driving mechanism including a first driving component, the output end of the first driving component reciprocating in the up-down direction;

[0008] A drilling mechanism is connected to the output end of the first drive component, and the drilling mechanism includes a drill bit;

[0009] A protective cover is provided with a dustproof chamber with an opening facing downwards. The drilling mechanism is located inside the dustproof chamber. The protective cover is connected to a telescopic mechanism. The other end of the telescopic mechanism is connected to the output end of the first drive component. The protective cover is configured such that when the drill bit drills a hole in the circuit board, the lower end of the protective cover abuts against the circuit board.

[0010] A clamping mechanism is provided for clamping a circuit board. A collection cavity is provided below the clamping mechanism and is located on the worktable.

[0011] The present invention has at least the following beneficial effects: the clamping mechanism clamps the circuit board, fixing the circuit board and the worktable relatively. The first drive assembly drives the drilling mechanism and the protective cover to move downwards. When the drill bit drills the circuit board, the lower end of the protective cover abuts against the circuit board, forming a closed dust-proof chamber with the circuit board. The debris generated by the drill bit is collected in the upper dust-proof chamber and the lower collection chamber, preventing debris from flying and making the production workshop dirty, and also preventing workers from inhaling the debris and affecting their health. The protective cover is connected to a telescopic mechanism. When the protective cover abuts against the circuit board but the drill bit has not yet drilled, the telescopic mechanism automatically retracts so that the protective cover does not affect the downward-moving drill bit, avoiding interference between the drill bit and the protective cover.

[0012] As a further improvement to the above technical solution, the lower end of the protective cover is lower than or equal to the lower end of the drill bit.

[0013] As a further improvement to the above technical solution, the telescopic mechanism is an elastic element and / or a telescopic rod.

[0014] As a further improvement to the above technical solution, the protective cover is provided with a buffer component connected to the circuit board at one end facing the drill bit.

[0015] As a further improvement to the above technical solution, the buffer is annular and has an upward-facing insertion groove, and the lower end of the protective cover is inserted into the insertion groove.

[0016] As a further improvement to the above technical solution, the circuit board drilling equipment also includes a negative pressure mechanism, which includes a first suction end and a second suction end. The first suction end is connected to the dust-proof chamber, and the second suction end is connected to the collection chamber.

[0017] As a further improvement to the above technical solution, the negative pressure mechanism and the first drive component are linked together.

[0018] As a further improvement to the above technical solution, the negative pressure mechanism includes a negative pressure fan, a filter element and two connecting pipes. The suction end of the negative pressure fan is connected to the filter element, the filter element is connected to the two connecting pipes respectively, and the two connecting pipes are connected to the dust isolation chamber and the collection chamber respectively.

[0020] As a further improvement to the above technical solution, the drilling mechanism also includes a drilling motor and a motor base. The drilling motor is installed in the motor base, and the output end of the drilling motor extends out of the motor base and is connected to the drill bit. Attached Figure Description

[0039] Reference Figures 1 to 3 The following are several embodiments of the circuit board drilling equipment of this utility model.

[0040] like Figures 1 to 3 As shown, the circuit board drilling device 100 of this utility model embodiment includes a worktable 200 for drilling, and the worktable 200 is provided with a drive mechanism 300, a drilling mechanism, a protective cover 500 and a clamping mechanism 700.

[0041] It is understandable that the drive mechanism 300 includes a first drive component 310, such as... Figures 1 to 3 As shown, the output end of the first drive component 310 reciprocates in the vertical direction and is connected to the drilling mechanism. The drilling mechanism includes a drill bit 430, such as... Figure 3 As shown, the output of the first drive component 310 can drive the drill bit 430 to move downward, so that the drill bit 430 drills a hole in the circuit board 720.

[0042] Understandably, the protective cover 500 has a downward-facing dustproof chamber 510, such as... Figure 3As shown. The protective cover 500 is fitted with a drilling mechanism, which is located inside the dust-proof chamber 510. When the drill bit 430 drills into the circuit board 720, the debris from the circuit board 720 drilled out by the drill bit 430 will be blocked by the inner wall of the protective cover 500 and collected in the dust-proof chamber 510. This prevents the debris from drifting to various parts of the production workshop, causing the production workshop to become dirty and messy, and preventing workers from inhaling the debris during the processing, which could affect their health.

[0043] Understandably, the output of the first drive assembly 310 passes through the protective cover 500 before being connected to the drilling mechanism.

[0044] Understandably, the workbench 200 is also equipped with a telescopic mechanism 600, such as... Figure 1 and Figure 2 As shown. The telescopic mechanism 600 includes a first telescopic end and a second telescopic end that are configured to extend vertically. The first telescopic end is connected to the protective cover 500, and the second telescopic end is connected to the output end of the first drive assembly 310. Under normal circumstances, when there is no external force acting on the protective cover 500, the telescopic mechanism 600 is naturally stretched by the gravity of the protective cover 500.

[0045] With this configuration, the output end of the first drive component 310 drives the drilling mechanism to move downward, while also driving the telescopic mechanism 600 and its connected protective cover 500 to move downward, so that the lower end of the protective cover 500 can connect with the circuit board 720. The connected protective cover 500 and the circuit board 720 form a closed dustproof chamber 510, avoiding gaps between the protective cover 500 and the drill bit 430, and preventing debris from flying out of the dustproof chamber 510 from the gap between the protective cover 500 and the drill bit 430, which would cause the production workshop to become dirty and affect the health of workers.

[0046] Moreover, when the lower end of the protective cover 500 is connected to the circuit board 720, the protective cover 500 and the circuit board 720 are relatively fixed. The first drive component 310 still drives the drilling mechanism to move down, so that the drill bit 430 drills a hole in the circuit board 720. At this time, the telescopic mechanism 600 extends and retracts to avoid interference between the protective cover 500 and the downward-moving drilling mechanism, which would affect the drilling process of the circuit board 720.

[0047] It is understandable that the clamping mechanism 700 is used to clamp the circuit board 720, such as Figure 1 and Figure 3 As shown, this design fixes the circuit board 720 relative to the worktable 200, preventing the circuit board 720 from shifting during drilling. A collection cavity 210 is connected to the lower part of the clamping mechanism 700, and the collection cavity 210 is located on the worktable 200. Figure 3As shown. Therefore, when the drill bit 430 processes the circuit board 720, the debris floating above the circuit board 720 is blocked by the protective cover 500 in the dust isolation chamber 510, and the debris floating below the circuit board 720 is blocked in the collection chamber 210, thus preventing the debris from floating in the production workshop.

[0048] In some embodiments, the lower end of the protective cover 500 is lower than the lower end of the drill bit 430. Before the drill bit 430 comes into contact with the circuit board 720, the protective cover 500 is already in contact with the circuit board 720, and the dust isolation chamber 510 is sealed so that the protective cover 500, which prevents debris from flying out, is already in place before the drill bit 430 drills out debris from the circuit board 720.

[0049] In other embodiments, the lower end of the protective cover 500 is equal to the lower end of the drill bit 430, that is, the lower end of the protective cover 500 is flush with the lower end of the drill bit 430. In this way, when the drill bit 430 is in contact with the circuit board 720, the protective cover 500 is in contact with the circuit board 720, preventing debris from splashing into the production workshop from the gap between the two.

[0050] In some embodiments, the telescopic mechanism 600 is an elastic element 610. The first telescopic end and the second telescopic end are the upper and lower ends of the elastic element 610, respectively. The elastic element 610 achieves stretching and contraction through its own elastic potential energy, so that even when the protective cover 500 is not connected to the circuit board 720 and remains stationary, the output end of the first drive component 310 can still drive the drill bit 430 to move downward.

[0051] Understandably, the elastic potential energy of the elastic element 610 can also make the protective cover 500 and the circuit board 720 abut against each other, making the connection between the protective cover 500 and the circuit board 720 tighter and preventing debris from flying out of the dust isolation chamber 510.

[0052] Furthermore, the elastic element 610 also acts as a buffer, cushioning the impact of the descending protective cover 500 on the circuit board 720, and preventing the protective cover 500 from rebounding upwards, causing the debris drilled by the drill bit 430 to fly out of the dust isolation chamber 510.

[0053] In some other embodiments, the telescopic mechanism 600 is a telescopic rod 620. The first telescopic end and the second telescopic end are the upper and lower ends of the telescopic rod 620, respectively. When the protective cover 500 hangs down naturally, the telescopic rod 620 automatically extends; when the protective cover 500 is connected to the circuit board 720 and the output end of the first drive assembly 310 is still moving downward, the telescopic rod 620 automatically retracts.

[0054] Understandably, the telescopic rod 620 can also guide the up and down movement of the protective cover 500 to prevent the protective cover 500 from shifting, coming into contact with the drill bit 430, damaging the protective cover 500, or affecting the accuracy of the drill bit 430 in processing the circuit board 720.

[0055] In this embodiment, the telescopic mechanism 600 includes an elastic element 610 and a telescopic rod 620. The elastic element 610 is sleeved on the telescopic rod 620, such as... Figure 1 As shown, the protective cover 500 can both abut against the circuit board 720 via the elastic element 610 and precisely rise and fall relative to the first drive assembly 310 via the telescopic rod 620. The elastic element 610 is a spring.

[0056] Understandably, the lower end of the protective cover 500, driven by the first drive component 310, will still bump against the circuit board 720, causing damage to the circuit board 720.

[0057] To address this, the end of the protective cover 500 facing the drill bit 430 is equipped with a buffer 520, such as... Figure 2 and Figure 3 As shown. The connection between the protective cover 500 and the circuit board 720 is actually the connection between the buffer 520 and the circuit board 720, which prevents the rigid protective cover 500 from damaging the circuit board 720. The buffer 520 can also buffer the impact of the descending protective cover 500 on the circuit board 720, and avoid the situation where the telescopic mechanism 600 only has a telescopic rod 620.

[0058] Understandably, the cushioning component 520 is made of soft materials such as rubber, silicone, or polyvinyl chloride.

[0059] It is understood that the buffer 520 is annular and has an upward-facing insertion groove, into which the lower end of the protective cover 500 is inserted. Specifically, the annular buffer 520 can completely cover the lower edge of the protective cover 500. When projected vertically, the shape of the buffer 520 is the same as the outer shape of the protective cover 500. That is, when the protective cover 500 is cuboid or cylindrical, the buffer 520 is square or circular.

[0060] It is understandable that the lower end of the protective cover 500 can be fixedly inserted into the groove by means of gluing, nailing or other methods, so that the protective cover 500 and the buffer 520 are relatively fixed.

[0061] In this embodiment, the lower end of the protective cover 500 is interference-fitted into the mounting groove. When the buffer 520 ages and deforms, the buffer 520 will automatically fall off from the lower end of the protective cover 500, and the worker can put a new buffer 520 into the lower end of the protective cover 500.

[0062] It is understood that the circuit board drilling equipment 100 also includes a negative pressure mechanism, which includes a first suction end and a second suction end. The first suction end is connected to the dust isolation chamber 510, and the second suction end is connected to the collection chamber 210.

[0063] With this configuration, when the negative pressure mechanism is activated, the first suction end absorbs the debris generated in the dust-proof chamber 510, and the second suction end absorbs the debris generated in the collection chamber 210. With this configuration, the debris attached to the circuit board 720, the dust-proof chamber 510, or the collection chamber 210 all pass through the negative pressure mechanism. When the drill bit 430 completes drilling and the first drive assembly 310 drives the drilling mechanism and the protective cover 500 to move upward, the upper and lower surfaces of the circuit board 720 are clean and tidy. Workers do not need to sweep away the debris attached to the circuit board 720, thus preventing the debris from flying around in the production workshop.

[0064] It is understandable that the negative pressure mechanism and the first drive component 310 are linked. Specifically, the negative pressure mechanism and the first drive component 310 are electrically connected. When drilling is performed, the first drive component 310 starts and drives the drilling mechanism downward. At the same time, the negative pressure mechanism is activated, allowing it to enter the working state in advance. When the drill bit 430 starts drilling, the negative pressure mechanism directly sucks up the debris generated by the drill bit 430.

[0065] In some embodiments, when the first drive component 310 drives the drilling mechanism to move upward, the drilling operation is completed, and the negative pressure mechanism closes in conjunction with the first drive component 310. The opening and closing of the negative pressure mechanism is controlled by the first drive component 310.

[0066] Understandably, when the first drive assembly 310 drives the drill bit 430 out of the hole in the circuit board 720, the debris hidden between the drill bit 430 and the circuit board 720 will be driven up to the dust isolation chamber 510 or fall into the collection chamber 210. At this time, the closed negative pressure mechanism can no longer suck up the debris.

[0067] In some embodiments, the telescopic mechanism 600 is connected to a pressure sensor. The pressure sensor is located between the first drive assembly 310 and the elastic member 610, and can detect the elastic force generated by the contraction of the elastic member 610 when the protective cover 500 is in contact with the circuit board 720.

[0068] Understandably, the pressure sensor and the negative pressure mechanism are wired together. When the pressure sensor detects no spring force, the protective cover 500 moves upward to separate from the circuit board 720, and the negative pressure mechanism shuts down. Since the lower end of the protective cover 500 is lower than or equal to the lower end of the drill bit 430, the protective cover 500 remains connected to the circuit board 720 even when the drill bit 430 has fully extended out of the drilled hole. At this time, the negative pressure mechanism is still activated, and it can suck up debris hidden between the drill bit 430 and the circuit board 720, ensuring that the debris is completely removed.

[0069] In this embodiment, the negative pressure mechanism includes a negative pressure fan 810, a filter element 820, and two connecting pipes 830, such as... Figure 3As shown. Specifically, the negative pressure fan 810 provides negative pressure suction to extract debris from the dust-proof chamber 510 and the collection chamber 210. The negative pressure fan 810 is mounted on the workbench 200. The suction end of the negative pressure fan 810 is connected to the filter element 820 so that the extracted debris is collected on the filter element 820, preventing debris from entering the negative pressure fan 810 and damaging it. The filter element 820 is located between two connecting pipes 830 and the negative pressure fan 810. One end of each connecting pipe 830 is connected to the filter element 820, and the other end is connected to the dust-proof chamber 510 and the collection chamber 210, respectively. When the negative pressure fan 810 is started, the negative pressure suction is diverted through the two connecting pipes 830 to the dust-proof chamber 510 and the collection chamber 210, ensuring that debris is collected from both.

[0070] It is understandable that the filter element 820 can be a filter screen or a filter bag. A collection box 840 is located below the workbench 200, and the filter element 820 is housed within the collection box 840, such as... Figure 3 As shown, the debris is isolated in the collection box 840 by the filter element 820. When cleaning the debris later, the debris inside the collection box 840 can be cleaned by tilting.

[0071] Furthermore, the collection box 840 can be slidably connected to the bottom of the workbench 200, and the debris inside the collection box 840 can be cleaned by pulling it out.

[0072] It is understandable that the connecting pipe 830 is a telescopic pipe. The telescopic pipe has good flexibility and extensibility and can adapt to the expansion and contraction of the pipe. When the output end of the first drive component 310 drives the protective cover 500 to move up and down, the telescopic pipe can effectively alleviate the connection problem caused by the displacement of the protective cover 500.

[0073] The drive mechanism 300 can also include a second drive component 320 and a third drive component 330, such as... Figure 1 As shown. The output end of the second drive component 320 extends in the left-right direction and is connected to the first drive component 310, that is, the second drive component 320 can drive the first drive component 310 to move left and right. The output end of the third drive component 330 extends in the front-back direction and is connected to the second drive component 320, that is, the third drive component 330 can drive the second drive component 320 to move back and forth.

[0074] With this configuration, the drilling assembly can achieve the position in the up-down, left-right, and front-back directions through the drive mechanism 300, enabling the drill bit 430 to precisely drill holes according to the required positions on the circuit board 720.

[0075] Understandably, the drilling mechanism also includes a drilling motor 410 and a motor base 420, such as Figure 3As shown. The drilling motor 410 is installed in the motor base 420. The output end of the drilling motor 410 extends out of the motor base 420 and is connected to the drill bit 430. The motor base 420 protects the drilling motor 410 and prevents the chips generated during processing from entering the drilling motor 410 and damaging its normal operation.

[0076] It is understandable that the clamping mechanism 700 is provided with an upward-facing clamping groove 710, such as... Figure 3 As shown, the shape and size of the circuit board 720 are opposite to the shape and size of the clamping groove 710, and the circuit board 720 is embedded in the clamping groove 710 from top to bottom. Since the protective cover 500 abuts against the circuit board 720 from top to bottom during drilling, no additional clamping tools are required for the circuit board 720 during processing, making the circuit board drilling equipment 100 simple in structure.

[0077] It is understandable that the lower end of the clamping mechanism 700 is hollow, that is, the clamping groove 710 is stepped groove. The clamping mechanism 700 provides support from the edge of the circuit board 720. The lower end of the clamping groove 710 is connected to the collection cavity 210 to avoid interference between the drill bit 430 and the clamping mechanism 700.

[0078] It is understood that the first drive assembly 310, the second drive assembly 320 and the third drive assembly 330 can be linear motion mechanisms such as lead screw motors, cylinders or hydraulic cylinders.

[0079] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
