Description

Technical Field

[0001] The utility model belongs to the technical field of PCB production, and particularly relates to a circuit board edge grinding device. Background Art

[0002] A circuit board can be called a printed wiring board or a printed circuit board, which is an important carrier for electronic components. During the production process of a circuit board, after the circuit board is divided, the edges need to be ground to remove the particles around the board to prevent dust from falling during production, which may affect the circuit connection quality and the performance of the circuit board.

[0003] The existing circuit boards are generally ground manually, but the efficiency of manual edge grinding is low and the labor cost is high. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an edge grinding device for circuit boards to solve the technical problems of low efficiency and high labor cost in manual edge grinding of circuit boards in the prior art.

[0005] The technical solution adopted to solve the above technical problems:

[0006] The utility model discloses an edge grinding device for circuit boards, including:

[0007] A machine base, on which a receiving member for receiving a circuit board is provided;

[0008] A clamping mechanism, which is rotatably connected to the machine base, the output end of the clamping mechanism is connected with a clamping member, and the clamping member and the receiving member are opposite to each other up and down;

[0009] A rotating mechanism, the output end of which is connected with the receiving member;

[0010] An edge grinding mechanism, the output end of which is connected with an edge grinding member, and the edge grinding member is located at the horizontal edges of the receiving member and the clamping member.

[0011] The utility model has at least the following beneficial effects: The circuit board is placed on the receiving member, and the clamping mechanism is started to clamp the circuit board between the clamping member and the receiving member. Then the rotating mechanism and the edge grinding mechanism are started. Since the clamping mechanism is rotatably connected to the machine base, the rotating mechanism can drive the receiving member, the circuit board, the clamping member and the clamping mechanism to rotate, so that the circuit board remains clamped during the rotation process. The started edge grinding mechanism drives the edge grinding member to rotate, so that the edge grinding member grinds the rotating circuit board, and the edge grinding operation of the circuit board is automatically completed. The circuit board edge grinding device does not require manual fixation of the circuit board or edge grinding of the circuit board, improves the edge grinding efficiency of the circuit board, and reduces the labor cost of circuit board production.

[0012] As a further improvement of the above technical solution, the receiving member is provided with a pressure sensor, and the clamping mechanism is configured such that when the detected pressure of the pressure sensor is greater than a preset pressure, the clamping mechanism is powered off.

[0013] With the above arrangement, the pressure sensor is used to detect the pressure exerted by the clamping member on the receiving member when the clamping mechanism is activated, and the pressure of the clamping member is controlled by the pressure sensor to prevent the circuit board from being crushed.

[0014] As a further improvement of the above technical solution, the machine base is connected with a protective cover, and the protective cover surrounds the clamping mechanism and the edge grinding mechanism.

[0015] With the above arrangement, the protective cover is used to prevent the sheet particles generated during the edge grinding of the circuit board from splashing, and to avoid the splashed sheet particles from entering the eyes, mouth, nose and other parts of the worker, which may endanger the health of the worker.

[0016] As a further improvement of the above technical solution, the protective cover is provided with an inlet and outlet for the circuit board to enter and exit, the machine base is provided with an ejecting mechanism, the output end of the ejecting mechanism is connected with an ejecting member, and the ejecting member and the inlet and outlet are arranged in a straight line.

[0017] With the above arrangement, the circuit board can be placed on the receiving plate surrounded by the protective cover through the inlet and outlet. The ejecting mechanism and the connected ejecting member can eject the edge-ground circuit board straight out of the inlet and outlet, which is convenient for the worker or equipment to take out the circuit board outside the protective cover, and keeps the connected protective cover and the machine base in a closed state all the time, without the worker repeatedly opening and closing the protective cover.

[0018] As a further improvement of the above technical solution, the ejecting member is higher than the receiving member, and the inner bottom surface of the inlet and outlet is at the same horizontal plane as the upper end surface of the receiving member.

[0019] With the above arrangement, the ejecting member is higher than the receiving member to prevent the ejecting member from colliding with the receiving member when the ejecting mechanism drives the ejecting member, which may cause the circuit board to not be ejected out of the inlet and outlet. The inner bottom surface of the inlet and outlet and the upper end surface of the receiving member are at the same horizontal plane, so that the circuit board can be horizontally received by the upper end surface of the receiving member or the lower end surface of the inlet and outlet when being put in or taken out.

[0020] As a further improvement of the above technical solution, the end of the inlet and outlet facing the ejecting member is in a trumpet shape with an opening getting larger.

[0021] With the above arrangement, the circuit board can be smoothly ejected out of the inlet and outlet by the ejecting mechanism and the ejecting member, and to avoid the circuit board from colliding with the edge of the inlet and outlet during the ejection process, which may cause the circuit board to break.

[0022] As a further improvement of the above technical solution, the machine base is provided with a limit screw hole, a limit bolt is threadedly connected to the limit screw hole, and the protective cover is provided with a connection hole corresponding to the limit screw hole.

[0023] With the above arrangement, after passing through the connection hole of the protective cover, the limit bolt is threadedly connected to the limit screw hole of the machine base, so that the protective cover and the machine base are fixedly connected, and the protective cover is limited and installed, making the front-to-back correspondence between the inlet and outlet and the ejecting member easier. Moreover, the connection between the two can be disassembled by loosening the limit bolt, which is convenient for cleaning the sheet particles on the protective cover and the machine base.

[0024] As a further improvement of the above technical solution, there are two grinding mechanisms and two grinding members, which are symmetrically arranged horizontally about the axis of the receiving member.

[0025] With the above arrangement, when the grinding mechanism is started, the two grinding mechanisms respectively drive the connected grinding members to rotate, so as to grind the opposite ends of the circuit board, improving the grinding efficiency of the circuit board.

[0026] As a further improvement of the above technical solution, the machine base is provided with an adjustment mechanism and a sliding groove. The adjustment mechanism includes an adjustment motor, an adjustment screw rod and two adjustment seats. The output end of the adjustment motor is connected to the adjustment screw rod. The adjustment screw rod is rotatably connected to the machine base. The adjustment screw rod is provided with two threaded sections with opposite directions. The two adjustment seats are respectively threadedly sleeved on the two threaded sections. After passing through the sliding groove, the two adjustment seats are respectively connected to the two grinding mechanisms.

[0027] With the above arrangement, the two grinding mechanisms can be simultaneously driven by the adjustment mechanism to approach or move away from each other along the sliding groove, so that the distance between the two grinding members can be adjusted according to the diameter of the circuit board to be ground, ensuring that the opposite ends of the circuit board are respectively in contact with the two grinding members, improving the applicability of the circuit board grinding equipment, and the circuit board placed on the receiving member can be accurately positioned by the two grinding members, facilitating the concentric setting of the circuit board and the receiving member.

[0028] As a further improvement of the above technical solution, there are two sliding grooves, which are symmetrically arranged about the axis of the receiving member.

[0029] With the above arrangement, the two sliding grooves are spaced apart to provide a position for the rotation connection of the clamping mechanism above the receiving member, and the two adjustment seats are respectively inserted into the two sliding grooves. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] In the description of the present utility model, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0049] Referring to Figures 1 to 3 , several embodiments of the circuit board edge grinding device of the present utility model are given below.

[0050] As Figures 1 to 3 shown, the circuit board edge grinding device of the embodiment of the present utility model includes a machine base 100, a rotating mechanism 300, a clamping mechanism 400, and an edge grinding mechanism 500.

[0051] It can be understood that a receiving member 200 is provided on the machine base 100. As Figure 2 and Figure 3 shown, workers can place the circuit board 900 on the receiving plate to provide a supporting effect for the circuit board 900.

[0052] It can be understood that a clamping member 410 is connected to the output end of the clamping mechanism 400. As Figures 1 to 3 shown, the clamping member 410 and the receiving member 200 are opposite up and down. When the clamping mechanism 400 is started, the output end of the clamping mechanism 400 drives the clamping member 410 to move in a direction close to or away from the receiving member 200, so that the clamping member 410 can move downward to firmly clamp the circuit board 900 between the clamping member 410 and the receiving member 200.

[0053] It can be understood that the output end of the rotating mechanism 300 is connected to the receiving member 200. As Figure 2 and Figure 3As shown. When the circuit board 900 is clamped between the clamping member 410 and the receiving member 200, the rotating mechanism 300 is started. Then, the receiving member 200 rotates with the output end of the rotating mechanism 300 as the rotation axis. Since the clamping mechanism 400 and the machine base 100 are rotationally connected through bearings, the rotating receiving member 200 drives the circuit board 900 and the clamping member 410 to rotate, facilitating the edge grinding of each arc edge of the circuit board 900.

[0054] It can be understood that a grinding member 510 is connected to the output end of the edge grinding mechanism 500, and the grinding member 510 is located at the horizontal edges of the receiving member 200 and the clamping member 410, as Figures 1 to 3 shown. When the edge grinding mechanism 500 is started, the output end of the edge grinding mechanism 500 drives the grinding member 510 to rotate to grind the edge of the circuit board 900 clamped by the receiving member 200 and the clamping member 410.

[0055] With such a setting, when using the circuit board edge grinding device, the worker needs to first place the circuit board 900 on the receiving member 200 and start the clamping mechanism 400 so that the clamping member 410 presses down to firmly clamp the circuit board 900 on the receiving member 200. Then, the rotating mechanism 300 and the edge grinding mechanism 500 are started. At this time, the output end of the rotating mechanism 300 drives the receiving member 200, the clamping member 410, and the clamped circuit board 900 to rotate, so that the arc edges of the circuit board 900 can all be rotated to contact the grinding member 510. The edge grinding mechanism 500 drives the grinding member 510 to rotate to grind the edge of the adjacent circuit board 900, automatically completing the edge grinding operation of the circuit board 900, improving the edge grinding efficiency of the circuit board 900. The worker only needs to put in or take out the circuit board 900, with low labor intensity and reduced labor costs required for production.

[0056] Furthermore, the circuit board 900 can be automatically placed on the receiving member 200 through a conveying device, eliminating the need for manual placement and removal of the circuit board 900, further reducing labor costs.

[0057] It can be understood that in order to avoid the situation where the circuit board 900 is broken due to excessive force when the clamping mechanism 400 drives the clamping member 410 to clamp the circuit board 900, the receiving member 200 is provided with a pressure sensor to detect the force condition of the receiving member 200 when the clamping member 410 moves towards the receiving member 200.

[0058] It can be understood that the circuit board edge grinding device is provided with a controller, which is electrically connected to the pressure sensor and the clamping mechanism 400 respectively. The preset pressure can be set through the controller. The pressure sensor converts the detected pressure signal into an electrical signal and sends it to the controller. The controller compares and analyzes the detected pressure and the preset pressure. When the detected pressure is greater than the preset pressure, the controller controls the clamping mechanism 400 to cut off the power, so as to maintain the clamping piece 410 in the position of clamping the circuit board 900 and prevent the clamping mechanism 400 from continuing to drive the clamping piece 410 to move downward to crush the circuit board 900.

[0059] It can be understood that the controller can also be electrically connected to the rotating mechanism 300 and the edge grinding mechanism 500 to turn on or off the rotating mechanism 300 and the edge grinding mechanism 500 through the controller.

[0060] It can be understood that the edge grinding mechanism 500 of the circuit board 900 is provided with a protective cover 600, as Figures 1 to 3 shown. The protective cover 600 is connected to the machine base 100 to form an enclosed space surrounding the clamping mechanism 400 and the edge grinding mechanism 500, preventing the flying of the plate particles ground during the edge grinding process from entering the eyes, nose, mouth and ears of the workers and endangering the life and health of the workers.

[0061] It can be understood that the edges of the protective cover 600 are all connected to the machine base 100 to prevent the particles from flying out through the gap between the protective cover 600 and the machine base 100.

[0062] It can be understood that when each circuit board 900 is placed on the receiving part 200, the worker needs to open the protective cover 600, take out the edge-ground circuit board 900, then put in the circuit board 900 to be edge-ground again, and then the worker needs to re-cover the protective cover 600, making the use of the protective cover 600 relatively inconvenient.

[0063] In this regard, the protective cover 600 is provided with an inlet and outlet 610, as Figures 1 to 3 shown. The inlet and outlet 610 is used for the circuit board 900 to enter and exit the protective cover 600. The area of the inlet and outlet 610 is small, and the number of plate particles that can fly out of the protective cover 600 through the inlet and outlet 610 is limited.

[0064] It can be understood that the machine base 100 is provided with an ejecting mechanism 700 and an ejecting part 710, as Figure 1 and Figure 3 shown. The ejecting part 710 is located in the enclosed space formed by the machine base 100 and the protective cover 600, and the ejecting mechanism 700 is located outside the enclosed space to reduce the front-back length of the enclosed space. The output end of the ejecting mechanism 700 is connected to the ejecting part 710, and the ejecting part 710 and the inlet and outlet 610 are arranged in a straight line.

[0065] With such a setting, when the ejection mechanism 700 is activated, the output end of the ejection mechanism 700 drives the ejector 710 to move towards the direction close to the inlet / outlet 610, so as to eject the edge-ground circuit board 900 out of the inlet / outlet 610; the output end of the ejection mechanism 700 can also drive the ejector 710 to move away from the inlet / outlet 610, so as to facilitate retracting the ejector 710, facilitating the worker to insert the circuit board 900 to be edge-ground through the inlet / outlet 610, so that the circuit board 900 can be received by the receiving member 200.

[0066] It can be understood that the worker can insert the circuit board 900 through a tool, avoiding insufficient insertion distance of the circuit board 900, resulting in the center of the clamped circuit board 900 and the center of the receiving member 200 not being on the same vertical line.

[0067] Furthermore, when the worker inserts the circuit board 900, the ejector 710 can be used to limit the insertion position of the circuit board 900, ensuring that the front and rear positions of the center of the circuit board 900 and the center position of the receiving member 200 are on the same vertical plane.

[0068] It can be understood that the ejector 710 is higher than the receiving member 200 to eject the circuit board 900 on the receiving member 200.

[0069] It can be understood that the inner bottom surface of the inlet / outlet 610 and the upper end surface of the receiving member 200 are on the same horizontal plane, so that when the circuit board 900 enters and exits the inlet / outlet 610, it can be horizontally received by the lower end surface of the inlet / outlet 610 and the upper end surface of the receiving member 200.

[0070] It can be understood that the ejection mechanism 700 is electrically connected to the controller to switch the ejection mechanism 700 through the controller.

[0071] Furthermore, one end of the inlet / outlet 610 facing the ejector 710 is in a flared shape with an increasing opening.

[0072] With such a setting, when the ejection mechanism 700 drives the ejector 710 to eject the circuit board 900, the circuit board 900 can smoothly penetrate into the inlet / outlet 610 along the opening of the flared shape, avoiding the situation where the ejected circuit board 900 is misaligned with the inlet / outlet 610, the circuit board 900 collides with the protective cover 600, and the circuit board 900 breaks.

[0073] It can be understood that the end of the inlet / outlet 610 far from the ejector 710 can also be in a flared shape with an increasing opening, so that when the worker inserts the circuit board 900 to be edge-ground, the circuit board 900 can also smoothly pass through the inlet / outlet 610, avoiding the circuit board 900 from bumping against the edge of the inlet / outlet 610.

[0074] In some embodiments, the flared end of the inlet / outlet 610 can be an inclined surface, so that the structure of the inlet / outlet 610 is simple and easier to manufacture.

[0075] In some other embodiments, the trumpet end of the inlet / outlet 610 may be an arc surface. The inlet / outlet 610 conducts the front end face and the rear end face of the protective cover 600, so that the edge of the end face of the protective cover 600 is in arc transition through the inlet / outlet 610, reducing the frictional effect between the circuit board 900 and the inner end face of the inlet / outlet 610.

[0076] It can be understood that the machine base 100 is provided with limit screw holes, the protective cover 600 is provided with connection holes corresponding to the limit screw holes, and the limit screw holes and the connection holes are correspondingly provided with limit bolts 620, as Figures 1 to 3 shown. During installation, the limit bolts 620 sequentially pass through the connection holes and are threadedly connected to the limit screw holes, thereby fixedly installing the protective cover 600 on the machine base 100. When the limit bolts 620 are screwed out of the limit screw holes, the protective cover 600 can be disassembled, which is convenient for cleaning the plate particles on the protective cover 600 and the machine base 100.

[0077] With such a setting, the installation positions of the protective cover 600 and the machine base 100 are fixed, the protective cover 600 can be limited, ensuring that the inlet / outlet 610 of the protective cover 600 corresponds to the ejector 710 before and after installation, and no alignment is required. The protective cover 600 is detachably connected to the machine base 100, making the disassembly and assembly of the protective cover 600 more convenient.

[0078] It can be understood that the detachable connection between the protective cover 600 and the machine base 100 can also be achieved by means of snap connection, magnetic attraction or magic tape, etc.

[0079] In some embodiments, there is one edging mechanism 500, and the edging member 510 is located on the left or right of the receiving member 200 to prevent the edging member 510 from affecting the entry and exit of the circuit board 900. The rotating mechanism 300 drives the receiving member 200 and the clamped circuit board 900 to rotate one circle, and all the arc edges of the circuit board 900 are edged by the edging member 510, with low efficiency.

[0080] In this embodiment, there are two edging mechanisms 500. Correspondingly, there are also two edging members 510 connected to the edging mechanisms 500. The circuit board 900 is edged by the two rotating edging members 510 at the same time, improving the edging efficiency, as Figure 1 and Figure 2 shown. The two edging mechanisms 500 are horizontally symmetrically arranged with the axis of the receiving member 200 as the axis of symmetry. During the edging operation of the circuit board 900, the opposite ends of the circuit board 900 are edged by the two edging members 510 at the same time. When the rotating mechanism 300 drives the clamped circuit board 900 to rotate half a circle, all the arc edges of the circuit board 900 pass through edging once.

[0081] It can be understood that the rotating mechanism 300 can drive the receiving member 200 to rotate multiple circles, improving the edge grinding effect of the circuit board 900.

[0082] It can be understood that the two edge grinding mechanisms 500 are respectively laid along the left-right direction, so that the two edge grinding members 510 are respectively located on the left and right sides of the receiving member 200, avoiding collision between the circuit board 900 entering and exiting front and back and the edge grinding member 510. Moreover, the two edge grinding members 510 arranged left and right can also limit the incoming circuit board 900 to ensure that the left and right positions of the center of the circuit board 900 and the center position of the receiving member 200 are on the same vertical plane.

[0083] It can be understood that the machine base 100 is provided with an adjusting mechanism 800 and a sliding groove 110, as Figure 1 shown. The adjusting mechanism 800 is used to adjust the position of the edge grinding mechanism 500, so that the edge grinding mechanism 500 can be applicable to circuit boards 900 with different diameters, improving the applicability of the circuit board edge grinding equipment.

[0084] In this embodiment, the adjusting mechanism 800 includes an adjusting motor 810, an adjusting screw 820 and an adjusting seat 830, as Figure 1 and Figure 2 shown.

[0085] It can be understood that the adjusting motor 810 is arranged on the machine base 100, and the output end of the adjusting motor 810 is connected to the adjusting screw 820 to drive the adjusting screw 820 to rotate.

[0086] It can be understood that the adjusting screw 820 extends along the left-right direction, and the left end and the right end of the adjusting screw 820 are rotationally connected to the machine base 100 through bearing seats. The adjusting screw 820 is provided with two thread segments 821 with opposite directions, and the two thread segments 821 are symmetrically arranged along the left-right direction, as Figure 1 and Figure 2 shown.

[0087] It can be understood that there are two adjusting seats 830. The two adjusting seats 830 are symmetric left and right and are respectively threadedly sleeved on the two thread segments 821. The sliding groove 110 extends along the left-right direction. The two adjusting seats 830 pass through the sliding groove 110 and are respectively connected to the two edge grinding mechanisms 500, as Figure 1 and Figure 2 shown.

[0088] With such a setting, when the adjusting motor 810 is started, the adjusting screw 820 rotates relative to the machine base 100, thereby driving the two adjusting seats 830 engaged by the threads to move left and right, and then making the two connected edge grinding mechanisms 500 move left and right, so that the two edge grinding members 510 approach or move away from each other, facilitating the adjustment of the left and right positions of the two edge grinding members 510 according to the diameter of the circuit board 900.

[0089] It can be understood that since the adjusting seat 830 is connected to the edge grinding mechanism 500 after passing through the sliding groove 110, the sliding groove 110 is used to guide the movement of the adjusting seat 830, so that the adjusting seat 830 can only move left and right along the sliding groove 110 and will not rotate with the adjusting screw 820 due to friction.

[0090] It can be understood that the adjusting motor 810 is electrically connected to the controller to adjust the adjusting motor 810 through the controller switch.

[0091] It can be understood that since a clamping mechanism 400 is provided above the receiving member 200.

[0092] In some embodiments, the top end of the clamping mechanism 400 can pass through the sliding groove 110 and be fixedly connected to the machine base 100.

[0093] In this embodiment, two sliding grooves 110 are provided and are symmetrically arranged left and right with respect to the axis of the receiving member 200, so that the sliding grooves 110 do not affect the connection and fixation of the clamping mechanism 400 and the machine base 100.

[0094] It can be understood that the rotating mechanism 300 and the edge grinding mechanism 500 are existing rotating motors, and the clamping mechanism 400 and the ejecting mechanism 700 are existing cylinders, oil cylinders or electric cylinders, etc. The present utility model does not make improvements to the structures of the rotating mechanism 300, the clamping mechanism 400, the edge grinding mechanism 500 and the ejecting mechanism 700. Therefore, those skilled in the art should understand the specific structures and working principles of the rotating mechanism 300, the clamping mechanism 400, the edge grinding mechanism 500 and the ejecting mechanism 700, and no specific explanation will be given here.

[0095] It can be understood that the edge grinding member 510 is an edge grinding roller in the shape of a cylinder. The receiving member 200 and the clamping member 410 are flat cylinders, so that the upper end surface of the receiving member 200 and the lower end surface of the clamping member 410 are both planes that can receive or clamp the circuit board 900. The ejecting member 710 can be plate-shaped or block-shaped, and the front side surface of the ejecting member 710 ejects the circuit board 900.

[0096] The above has specifically described the preferred embodiments of the present utility model, but the creation of the present utility model is not limited to the described embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present utility model, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
