Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor equipment, and in particular to a type changing device. Background Art

[0002] In modern industrial production, suction nozzles are widely used in the suction and transfer operations of various materials. In practical applications, due to the diversification of production needs, it is often necessary to retract and extend the suction nozzles and adjust the spacing to adapt to different working scenarios and material specifications.

[0003] The prior art (CN 201911400189.2) discloses a variable-spacing multi-nozzle suction head, which ventilates the cylinder air pipe joint, moves the cylinder, and drives the connecting plate to move by the cylinder piston head, thereby driving the push rod to make a linear motion in the linear bearing, driving the nozzle to move relative to each other, and adjusting the product spacing for direct assembly and testing. However, by additionally installing components such as cylinders on the nozzle device, there are too many parts in the nozzle device, which occupies a large area and is costly. Therefore, it is common in the prior art to set a movable nozzle assembly, unlock the nozzle when the nozzle spacing needs to be adjusted, and adjust the spacing through an external device; after the spacing adjustment is completed, lock the nozzle and remove the external device, so that the spacing adjustment process of all nozzles can be completed through an external device, which does not occupy the volume of the nozzle device body and is low in cost.

[0004] Because the suction nozzle needs to be unlocked before it can be retracted and the spacing can be adjusted. However, the unlocking process is currently mainly done manually. Each suction nozzle is provided with several locking points. The operator holds the unlocking tool and contacts the locking point to unlock the suction nozzle assembly. When the suction nozzle is adjusted, the unlocking tool is moved away from the locking point to restore the locking effect of the suction nozzle. However, the low efficiency of manual operation has seriously affected the overall production efficiency. In addition, the accuracy of manual unlocking is difficult to guarantee, and it is difficult to achieve precise control of the degree of nozzle unlocking, which may cause the nozzle to have position deviations during the subsequent retraction and spacing adjustment process, thereby affecting the accuracy of material absorption and transfer, and may even cause product quality problems and production failures. Summary of the invention

[0005] The object of the present invention is to provide a type changing device to solve the technical problems of low efficiency and poor precision caused by manual unlocking of the suction nozzle in the prior art.

The driving mechanism can drive the mold changing clips to move between an unlocking position and a locking position in a direction approaching or away from the locking point, thereby achieving an unlocking or locking effect of the suction nozzle assembly.

[0010] Preferably, a guide slot is provided on the support body, and at least a portion of the mold-changing clip is passed through the guide slot and is slidably connected to the guide slot.

After the mold changing operation is completed, the driving mechanism is controlled to drive the mold changing clip to move to the locking position in the direction away from the locking point, so that the mold changing clip is away from the locking point, thereby locking the locking point of the nozzle assembly to ensure the stable operation of the nozzle assembly. By setting the driving mechanism and the mold changing clip, the automatic operation of unlocking and locking the nozzle assembly is realized, replacing the traditional manual unlocking method, and the unlocking and locking process can be completed quickly, thereby improving work efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0031] See also Figure 1 and Figure 2 The mold changing device provided by the embodiment of the present invention includes a supporting body 1 and a mold changing assembly 2. The mold changing assembly 2 is arranged on the supporting body 1, and includes a driving mechanism 21 and at least two mold changing clips 22. The mold changing assembly 2 can be selectively connected with any suction nozzle assembly, so that the mold changing clips 22 correspond to the locking points one by one. The driving mechanism 21 can drive the mold changing clips 22 to move between the unlocking position and the locking position in the direction approaching or away from the locking point. When the mold changing clips 22 move to the unlocking position, the mold changing clips 22 contact the locking point, thereby achieving the unlocking effect of the suction nozzle assembly; when the mold changing clips 22 move to the locking position, the mold changing clips 22 are away from the locking point, thereby achieving the locking effect of the suction nozzle assembly.

[0032] The mold changing device proposed by the present invention, when in use, connects the mold changing assembly 2 with the nozzle assembly that needs to be changed, controls the driving mechanism 21 to drive the mold changing clamp 22 to move to the unlocking position in the direction close to the locking point, so that the mold changing clamp 22 contacts the locking point, thereby unlocking the locking point of the nozzle assembly, so that the nozzle assembly can perform mold changing operations such as retracting and releasing operations and spacing adjustment. After the mold changing operation is completed, the driving mechanism 21 is controlled to drive the mold changing clamp 22 to move to the locking position in the direction away from the locking point, so that the mold changing clamp 22 is away from the locking point, thereby locking the locking point of the nozzle assembly to ensure the stable operation of the nozzle assembly. By setting the driving mechanism 21 and the mold changing clamp 22, the automatic operation of unlocking and locking the nozzle assembly is realized, replacing the traditional manual unlocking method, and the unlocking and locking process can be completed quickly, thereby improving work efficiency. Secondly, the automated driving mechanism 21 can accurately control the movement of the mold changing clamp 22, ensuring that it accurately corresponds to the locking point and performs unlocking or locking operations, thereby effectively improving the operating accuracy. This avoids problems such as inconsistent unlocking degrees and position deviations caused by subjectivity and differences in manual operation, and ensures the accuracy of the nozzle assembly in the subsequent retraction and spacing adjustment process.

[0033] The specific structure of the type-changing device is described below.

[0034] In the mold changing assembly 2, the unlocking effect of the nozzle assembly can be achieved by moving the mold changing clip 22 and connecting it with the locking point. In order to optimize the moving path of the mold changing clip 22, a guide slot 11 is provided on the support body 1, and at least part of the mold changing clip 22 is inserted into the guide slot 11 and is slidably connected to the guide slot 11. On the one hand, the guide slot 11 can ensure that the mold changing clip 22 maintains linear motion during movement to avoid deviation or shaking, thereby improving the alignment accuracy of the mold changing clip 22 and the locking point. On the other hand, the guide slot 11 provides guidance and constraints for the movement of the mold changing clip 22, reduces the friction resistance of the mold changing clip 22 during movement, and enables the driving mechanism 21 to more easily drive the mold changing clip 22 to move, thereby reducing the energy consumption and wear of the driving mechanism 21, extending the service life of the driving mechanism 21, and also helping to improve the operating stability and durability of the entire mold changing device.

[0035] The driving mechanism 21 is used to realize the movement process of the mold changing clamp 22. Specifically, the driving mechanism 21 includes a rotating motor 211 and a transmission gear 212. A rack 221 is provided on at least part of the mold changing clamp 22. The transmission gear 212 is coaxially connected to the motor shaft of the rotating motor 211, and the transmission gear 212 and the rack 221 are meshed with each other. When in use, the rotating motor 211 is driven to rotate, and the transmission gear 212 can be driven to rotate synchronously through the rotation of the motor shaft. Under the meshing action of the transmission gear 212 and the rack 221, the mold changing clamp 22 is driven to move in a straight line direction. The transmission mode in which the rotating motor 211 and the transmission gear 212 are meshed with the rack 221 can provide stable and accurate power transmission, and convert the rotational motion of the motor shaft of the rotating motor 211 into the linear motion of the mold changing clamp 22. The rotating motor 211 has good speed regulation performance, and can accurately adjust the moving speed of the mold changing clamp 22 according to actual needs, thereby realizing more sophisticated unlocking and locking operations. In addition, the meshing transmission between the transmission gear 212 and the rack 221 has good self-locking performance. When the rotating motor 211 stops working, it can effectively prevent the mold changing clamp 22 from accidentally moving due to external force or gravity, thereby improving the safety and stability of the mold changing clamp 22.

[0036] In other embodiments, the driving mechanism 21 may also be a telescopic motor, and the end of the mold changing clamp 22 away from the locking point is connected to the motor shaft of the telescopic motor. The telescopic motor drives the telescopic shaft to extend and retract, which will not be elaborated here.

[0037] It is worth noting that in this embodiment, a driving mechanism 21 is independently provided for each mold changing clamp 22. The independent driving mechanism 21 can accurately and independently control each mold changing clamp 22, so that the action of the corresponding mold changing clamp 22 can be flexibly adjusted according to the specific needs and working state of each nozzle assembly, and personalized and refined unlocking and locking operations can be achieved, thereby improving the adaptability and flexibility of the mold changing device.

[0038] In other embodiments, a plurality of mold changing clamps 22 may share one driving mechanism 21 , which is not limited here.

[0039] Specifically, a limit block is provided at one end of the mold changing clamp 22 away from the locking point, and when the mold changing clamp 22 reaches the unlocking position, the limit block abuts against the supporting body 1. When the mold changing clamp 22 reaches the unlocking position, the limit block abuts against the supporting body 1, which can accurately limit the moving stroke of the mold changing clamp 22 to ensure that it does not move excessively, thereby ensuring the accuracy and stability of the unlocking position, and effectively avoiding device failure or operational errors that may be caused by excessive unlocking.

[0040] Regarding the specific structure of the mold changing clamp 22. The mold changing clamp 22 includes a first clamping plate 222 and a second clamping plate 223, which are jointly arranged to form a clamping space, which can better adapt to locking points of different shapes and sizes. Part of the suction nozzle assembly can be inserted into the clamping space, so that the ends of the first clamping plate 222 and the second clamping plate 223 can effectively abut against the locking point to achieve an unlocking effect, prevent the suction nozzle assembly from interfering with the movement process of the mold changing clamp 22, and improve the versatility and applicability of the mold changing clamp 22.

[0041] Specifically, an elastic cushion is provided in the clamping space. The elastic cushion can increase the friction between the mold changing clamp 22 and the nozzle assembly, making the clamping more stable and preventing the mold changing clamp 22 and the nozzle assembly from sliding relative to each other during operation, thereby ensuring the accuracy and reliability of the unlocking and locking operations. In addition, the elastic cushion has a certain buffering effect, which can reduce the impact force generated by the mold changing clamp 22 when clamping the locking point, avoiding damage to the locking point and the mold changing clamp 22, and extending the service life of the equipment.

[0042] The elastic cushion layer may be a rubber layer, a silicone layer, etc., which will not be elaborated here.

[0043] Specifically, a limiting groove 224 is provided at the end of the mold changing clip 22. The limiting groove 224 can form a better fit and positioning with the locking point. When performing unlocking and locking operations, the locking point can be accurately embedded in the limiting groove 224, ensuring that the connection between the mold changing clip 22 and the locking point is more stable and accurate, thereby improving the accuracy and reliability of the unlocking and locking operations.

[0044] It is understandable that the shape and setting position of the limiting groove 224 need to be adaptively adjusted according to the structure of the locking point, which is not limited here.

[0045] In addition, a pressure sensor is provided at the position where the mold changing clamp 22 contacts the locking point to monitor the contact pressure. Specifically, a groove is provided at the position where the end of the mold changing clamp 22 contacts the locking point, and a pressure sensor is embedded in the groove. When the nozzle assembly is unlocked, the mold changing clamp 22 moves toward and contacts the locking point. At this time, the pressure sensor monitors the contact pressure between the mold changing clamp 22 and the locking point in real time, and transmits the pressure data to the control system. If the pressure value is lower than the critical pressure value, the control system determines that the unlocking is unsuccessful, that is, the mold changing clamp 22 cannot push the locking point to realize the unlocking process, and issues an alarm to remind the operator to adjust the movement of the mold changing clamp 22; if the pressure value is higher than the rated pressure value, the control system will immediately stop the further movement of the mold changing clamp 22 to prevent damage to the locking point or the equipment.

[0046] Among them, the critical pressure value and the rated pressure value need to be adaptively selected according to actual needs and are not limited here.

[0047] Since the mold changing device provided in this embodiment needs to cooperate with multiple other devices to operate synchronously during use, in order to prevent the other devices from being started before the mold changing clamp 22 has completely reached the unlocking position or the locking position, which may easily cause interference between the devices, the mold changing device also includes a monitoring component, which can monitor the position of the mold changing clamp 22 and generate prompt information. The monitoring component can monitor the position of the mold changing clamp 22 in real time and accurately, so that the operator can understand the working status of the mold changing clamp 22 at any time and find abnormal situations in time, such as the mold changing clamp 22 has not reached the specified position or the position deviation, so that measures can be taken quickly to adjust, avoid unlocking or locking failures caused by position errors, and improve the accuracy and reliability of the operation. The generated prompt information can intuitively inform the operator of the current position and operation progress of the mold changing clamp 22, which helps the operator to better control the entire mold changing process, improve work efficiency, and reduce operating errors and waiting time.

[0048] Specifically, the monitoring component includes a sensor 3, and two sensors 3 are provided for each mold changing clamp 22, wherein one sensor 3 is used to determine whether the mold changing clamp 22 has reached the unlocking position, and the other sensor 3 is used to determine whether the mold changing clamp 22 has reached the locking position. By respectively providing a sensor 3 for determining the unlocking position and the locking position for each mold changing clamp 22, accurate and independent monitoring of the position of the mold changing clamp 22 is achieved, ensuring that the position of the mold changing clamp 22 is accurately determined during the unlocking and locking operations. Moreover, the two independent sensors 3 can work simultaneously without interfering with each other, thereby improving the efficiency and real-time performance of monitoring. During the movement of the mold changing clamp 22, it can quickly provide feedback on whether it has reached the target position, so that the control system can respond in time and adjust the operation, further shortening the time of the mold changing operation and improving production efficiency.

[0049] It is understandable that the sensor 3 is an existing electrical device in the art, and its working principle and specific structure are not described in detail here.
