Description

Technical Field

[0001] The present application relates to the field of semiconductor production and processing technology, and in particular, to a quartz powder grinding device and system. Background Art

[0002] In the production process of bipolar integrated circuit products, quartz powder is needed. The inventors of this application have found that quartz powder is prone to absorb impurities such as water vapor after long-term storage, which causes its particle size to become larger and does not meet the process requirements. In the traditional scheme, the quartz powder is usually ground manually, and then the powder is manually screened. The screened quartz powder is then dried and other operations are performed to reduce the particle size of the quartz powder. However, manual processing cannot meet the uniform grinding requirements due to the uneven force, which will have a great impact on the quality consistency of subsequent bipolar integrated circuit products. In addition, manual grinding will also increase the labor intensity of the operator and reduce the grinding efficiency. Summary of the invention

[0044] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the drawings in the present application are only for the purpose of illustration and description and are not used to limit the scope of protection of the present application. In addition, it should be understood that the schematic drawings are not drawn to scale. The flowcharts used in this application illustrate the operations implemented according to some embodiments of the embodiments of the present application.

[0045] Please refer to Figure 1 , is a schematic diagram of the structure of the quartz powder grinding device provided in the embodiment of the present application. Figure 1 As shown, the quartz powder grinding device 100 may include a grinding platform 110 , a grinding transmission assembly 120 , a control assembly 130 , a grinding assembly 140 and a support assembly 150 .

[0046] In detail, the grinding platform 110 may include an upper cover 112 and a base 114 fixed to the upper cover 112. The upper cover 112 is provided with a travel slot 116. The grinding transmission assembly 120 is disposed in the travel slot 116 and can reciprocate between the two ends of the travel slot 116.

[0047] In this embodiment, a grinding groove 122 is provided on the grinding transmission assembly 120, and quartz powder to be ground can be accommodated in the grinding groove 122. For example, the quartz powder can be but is not limited to ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused quartz sand, silicon powder, etc.

[0048] In this embodiment, the control component 130 is connected to the grinding transmission component 120, so as to control the grinding transmission component 120 to reciprocate between the two ends of the travel groove 116. During the reciprocating transmission of the grinding transmission component 120, the grinding component 140 can grind the quartz powder in the grinding groove 122. The grinding component 140 can be fixed on the upper cover 112 by the support component 150, and the grinding force of the quartz powder can be adjusted under the control of the support component 150.

[0049] Based on the above design, the quartz powder grinding device 100 provided in this embodiment is designed with a grinding platform 110, a travel groove 116 is provided on the upper cover 112 of the grinding platform 110, the control component 130 controls the grinding transmission component 120 to reciprocate between the two ends of the travel groove 116, and the grinding transmission component 120 is provided with a grinding groove 122 for accommodating quartz powder, and the grinding component 140 is fixed on the upper cover 112 through the support component 150, and the quartz powder is ground during the reciprocating transmission of the grinding transmission component 120, and the grinding force of the quartz powder is uniformly adjusted under the control of the support component 150. In this way, by simulating the manual grinding process of the operator and optimizing the force control, the force uniformity of the quartz powder grinding can be improved, so as to better meet the uniform grinding requirements, thereby facilitating the improvement of the quality consistency of subsequent bipolar integrated circuit products, and in addition, the labor intensity of the operator can be effectively reduced and the grinding efficiency can be improved.

[0050] In a possible implementation manner, in order to facilitate the control of the grinding transmission assembly 120 and reduce the friction during the transmission process, please refer to Figure 2-Figure 4 The grinding transmission assembly 120 may further include a grinding transmission body 123 , a gear 125 , a rack 126 and a pulley 127 .

[0051] The gear 125 is disposed on the side plate 124 of the grinding transmission body 123. For example, a fixing hole is provided on the side plate 124, and the gear 125 is fixed to the side plate 124 through the fixing hole and a fixing screw. The gear 125 is connected to the control component 130 and can rotate relative to the side plate 124 under the control of the control component 130.

[0052] The rack 126 is disposed on the side plate 124 of the grinding transmission body 123 and meshes with the gear 125. The transmission direction of the rack 126 is parallel to the extension direction of the travel groove 116. When the gear 125 rotates, it can drive the rack 126 to transmit.

[0053] The pulley 127 is disposed at the bottom of the grinding transmission body 123. During the grinding process of the quartz powder, the gear 125 can drive the rack 126 to reciprocate under the control of the control component 130, so as to drive the pulley 127 to reciprocate between the two ends of the travel groove 116. In this process, the quartz powder in the grinding groove 122 also reciprocates between the two ends of the travel groove 116, so that the quartz powder can be repeatedly ground by the grinding component.

[0054] Based on the above design, by designing the transmission structure of the gear 125 and the rack 126 to drive the reciprocating transmission of the entire grinding transmission assembly 120, the control of the grinding transmission assembly 120 can be facilitated, and by designing the pulley 127, the friction force in the transmission process can be effectively reduced and the transmission efficiency can be improved.

[0055] In one possible implementation, combining Figure 4 As shown, in order to improve the stability of the pulley 127, pulley support plates 128 may be further provided on both sides of the pulley 127, a pulley through hole 1285 is opened on the pulley support plate 128, and the pulley 127 may include a rotating shaft 1271 that passes through the pulley through hole 1285 and is movably connected to the pulley support plate 128.

[0056] In one possible implementation, combining Figure 5 As shown, the control component 130 may specifically include a control motor 132, a relay electrically connected to the control motor 132 ( Figure 5 ), and pressure sensors (not shown) respectively disposed at both ends of the travel groove 116 and electrically connected to the relay. Figure 5 The upper cover 112 may be provided with a motor through hole 1122 , and the rotating shaft 134 of the control motor 132 may pass through the motor through hole 1122 and be connected to the gear 125 .

[0057] When the grinding transmission assembly 120 is transmitted to any end of the travel groove 116, the pressure sensor at the end generates a pressure trigger signal and sends the pressure trigger signal to the relay. When the relay detects the pressure trigger signal, it causes the control motor 132 to rotate in a transmission direction opposite to the current transmission direction. For example, it can be set that when the pressure intensity reaches a set intensity, the pressure trigger signal is sent to the relay. The set intensity can be determined after testing based on the actual weight of the grinding transmission assembly 120, and is not specifically limited here.

[0058] Thus, the grinding transmission assembly 120 can be driven to continue transmission toward the other end of the travel groove 116, thereby realizing reciprocating transmission.

[0059] In one possible implementation, combining Figure 6 As shown, the grinding assembly 140 may specifically include a grinding roller 142 and support connectors 144 located at both ends of the grinding roller 142. The support connectors 144 may cooperate with the support assembly 150 to be fixed on the upper cover 112.

[0060] Optionally, the grinding roller 142 can be made of quartz material.

[0061] In one possible implementation, combining Figure 7 As shown, in order to facilitate supporting the grinding assembly 140 , the support assembly 150 may include a first support bracket 152 , a second support bracket 154 , a clamping member 156 and a support bracket 158 ​​.

[0062] In this embodiment, the first support bracket 152 may include a first ring-shaped portion 1522 and a first support portion 1524 located at both ends of the first ring-shaped portion 1522, and the second support bracket 154 may include a second ring-shaped portion 1542 and a second support portion 1544 located at both ends of the second ring-shaped portion 1542. The first ring-shaped portion 1522 and the second ring-shaped portion 1542 constitute a ring-shaped space for ring-shaped grinding roller 142, and the grinding roller 142 passes through the ring-shaped space and is fixedly contacted with the first support bracket 152 and the second support bracket 154.

[0063] In this embodiment, the shapes of the first ring-shaped portion 1522 and the second ring-shaped portion 1542 can be adaptively designed according to the shape of the grinding roller 142. For example, when the shape of the grinding roller 142 is cylindrical, the first ring-shaped portion 1522 and the second ring-shaped portion 1542 can respectively adopt hollow semi-cylindrical ring pieces, and the radius of the formed ring-shaped space matches the radius of the grinding roller 142.

[0064] In this embodiment, in order to facilitate the effective fixation of the grinding roller 142, a first through hole 1526 is provided on the first support portion 1524, and a second through hole 1546 corresponding to the first through hole 1526 is provided on the second support portion 1544. The support bracket 158 ​​passes through the second through hole 1546 and the first through hole 1526 in sequence and is fixedly connected to the first support portion 1524 and the second support portion 1544 through the fixing piece 1528 at the first through hole 1526.

[0065] In this embodiment, the clamping member 156 can clamp the supporting bracket 158 ​​onto the upper cover 112 .

[0066] Exemplarily, the support bracket 158 ​​may include a support base 1582 and a support column 1584, one end of the support column 1584 is fixedly connected to the support base 1582, and the other end of the support column 1584 passes through the second through hole 1546 and the first through hole 1526 in sequence and is fixedly connected to the first support portion 1524 and the second support portion 1544 through the fixing member 1528 at the first through hole 1526. The support base 1582 is clamped with the clamping member 156 and fixed to the upper cover 112 through the clamping member 156.

[0067] In a possible implementation manner, in order to adjust the grinding force and grinding direction of the grinding roller 142, so as to improve the uniformity of the grinding force of the quartz powder, thereby better achieving the uniform grinding requirement, and thus facilitating the improvement of the quality consistency of subsequent bipolar integrated circuit products, still refer to Figure 7 An elastic member 159 may be sleeved on the support column 1584 , and one end of the elastic member 159 abuts against the support base 1582 , and the other end abuts against the first support portion 1524 .

[0068] There may be more than two support columns 1584. In the process of actually adjusting the grinding force and grinding direction of the grinding roller 142, the protruding length of each support column 1584 through the second through hole 1546 and the first through hole 1526 can be adjusted, and then each support column 1584 can be fixed by the fixing member 1528 at the first through hole 1526. The greater the protruding length of each support column 1584 through the second through hole 1546 and the first through hole 1526, the greater the grinding force of the grinding roller 142. For different support columns 1584, different protruding lengths through the second through hole 1546 and the first through hole 1526 can be designed to further adjust the grinding direction of the grinding roller 142.

[0069] In a possible implementation, please refer to Figure 8Next, the circuit structure schematic diagram of the control component 130 is exemplarily described. F1 is the control circuit fuse, and F2 is the control motor fuse. SB1 is the start button. After pressing SB1, the control motor 132 starts. K0 is the self-locking relay of the main control circuit. After SB1 is pressed, K0 will automatically pop open. At this time, the normally open contact of K0 is closed, and the circuit is self-locking and continuously powered. SB2 is the stop button. After SB2 is triggered, the main control circuit is powered off. S1 is the left limit switch. When the control motor 132 moves to the position of S1, the corresponding circuit is cut off or connected. S2 is the right limit switch. When the control motor 132 moves to the position of S2, the corresponding circuit is cut off or connected. K1 is a control relay that allows the control motor 132 to rotate in the first direction. When K1 is powered on, the control motor 132 rotates in the first direction. K2 is a control relay that allows the control motor 132 to rotate in the second direction. When K2 is powered on, the control motor 132 rotates in the second direction. M is a control motor 132, which can drive the grinding transmission assembly 120 to reciprocate. The first direction and the second direction are opposite directions.

[0070] Based on the above design principles, the circuit principle of the control component 130 is exemplarily described below in detail.

[0071] (1) When SB1 is pressed, it automatically pops open. At this time, the normally open contact of K0 closes, realizing circuit self-locking. At this time, the main control circuit continues to be energized.

[0072] (2) The current passes through the normally closed contacts of S1 and K2 to connect the K1 relay coil and activate it, connecting the normally open contacts of the K1 relay and disconnecting the normally closed contacts of K1. The normally open contacts of K1 in the circuit of the control motor 132 are closed, and the control motor 132 rotates in the first direction. At this time, the normally open contacts are connected to the power supply, and the grinding transmission assembly 120 moves in the first direction. The normally closed contacts of K1 in the control circuit of the K2 relay are disconnected, so that the K2 relay coil cannot be energized, and interlocking is achieved.

[0073] (3) When the grinding transmission assembly 120 moves to the position of S1, the normally open contact closes and the normally closed contact opens. The S2 switch is not triggered and does not move. The normally closed contact S1 in the K1 relay control circuit opens, causing the K1 relay coil to lose power, the K1 normally closed contact closes, and the normally open contact opens. The normally open contact K1 in the control motor 132 circuit opens, cutting off the power supply of the control motor 132 and causing the control motor 132 to stop. The normally open contact S1 in the K2 relay control circuit closes, and the normally closed contact of the K1 relay closes, causing the K2 relay coil to be energized and actuated, the normally open contact closes, and the normally closed contact opens. The normally closed contact K2 in the K1 relay control circuit opens, preventing the K1 relay coil from being energized, thereby achieving interlocking. The normally open contact K2 in the control motor 132 circuit is closed, causing the control motor 132 to rotate in the second direction. When the normally open contact K2 is powered on, the grinding transmission assembly 120 moves in the second direction. The normally open contact K2 in the K2 relay control circuit is closed, causing the grinding transmission assembly 120 to move in the second direction and leave the left limit switch. After that, the circuit remains energized to achieve self-locking.

[0074] (4) When the grinding transmission assembly 120 moves to the position of S2, the normally open contact of S2 is closed and the normally closed contact is disconnected, and the S1 switch is not triggered and does not move. The normally closed contact of S2 in the K2 relay control circuit is disconnected, cutting off the K2 relay control circuit, and the K2 relay loses power, the normally closed contact is closed, and the normally open contact is disconnected. In the circuit of the control motor 132, the normally open contact of relay K2 is disconnected, cutting off the power supply of the control motor 132, thereby stopping the control motor 132 from being energized. The normally open contact of K2 in the K2 relay control circuit is disconnected, ending the self-locking state of the K2 control circuit. The normally closed contact of K2 in the K1 relay control circuit is closed, connecting the K1 relay control circuit, and on this basis, the action of part (2) can be repeated to achieve the reciprocating motion of the grinding transmission assembly 120.

[0075] (5) Before pressing SB1, the grinding transmission assembly 120 is in a position other than S1 and S2. When SB1 is pressed, the circuit starts to work from (2).

[0076] Before SB1 is pressed, the grinding transmission assembly 120 is in the left limit switch position, and when SB1 is pressed, the circuit starts to work from (3).

[0077] Before SB1 is pressed, the grinding transmission assembly 120 is in the right limit switch position, and when SB1 is pressed, the circuit starts to work from (4).

[0078] That is, the grinding transmission assembly 120 can be in any position before starting the machine, and pressing SB1 can realize the reciprocating motion of the grinding transmission assembly 120.

[0079] (6) During the operation of the grinding transmission assembly 120, SB2 is pressed at any time to cut off the main control circuit, and the K0, K1 and K2 relays are all de-energized. The normally open contact of K0 is disconnected to end the self-locking state of the main control circuit. The normally open contacts of the relays K1 and K2 in the control motor 132 circuit are all disconnected, cutting off the power supply of the control motor 132, thereby stopping the control motor 132.

[0080] Furthermore, based on the same inventive concept, a quartz powder grinding system is provided, which includes a grinding control device and the above-mentioned quartz powder grinding device 100 connected to the grinding control device, and the grinding control device can be used to control the quartz powder grinding device 100.
