Description

[0002] At present, in order to reduce the resistance suffered by the workpiece transport frame of the processing device, a roller is usually installed on the workpiece transport frame, so that the workpiece transport frame can smoothly move on the rack of the processing device. In order to enable the workpiece transport frame to be parked at a certain processing station, the rack of the processing device is usually provided with a positioning device at a position corresponding to the processing station. When the workpiece transport frame contacts the positioning device, the positioning device can limit the position of the workpiece transport frame.

[0035] A first aspect of the present application provides a positioning device 100, which can be applied to various processing equipment, such as circuit board processing equipment, plastic part processing equipment, etc. The positioning device 100 is applied to circuit board processing equipment as an example, and the positioning device 100 provided by the embodiments of the present application is described in conjunction with the accompanying drawings.

[0036] Please refer to Figure 2 The positioning device 100 described above includes a mounting frame 110, a positioning assembly 120, a first swing arm 130, a second swing arm 140, and an elastic assembly 150. The positioning assembly 120 includes a positioning piece 121, which is spaced apart from the mounting frame 110. Understandably, the positioning piece 121 can be spaced apart from the mounting frame 110 in an up-down direction or a left-right direction. The positioning piece 121 is provided with a clamping portion, which is clamped with a workpiece transport frame 300 to limit the position of the workpiece transport frame 300. Understandably, in the circuit board processing equipment, the workpiece transport frame 300 is used to transport circuit boards. One end of the first swing arm 130 is rotatably connected with the mounting frame 110, and the other end of the first swing arm 130 is rotatably connected with one end of the positioning piece 121. The second swing arm 140 is distributed along the movement direction of the workpiece transport frame 300 in sequence with the first swing arm 130, and the second swing arm 140 is arranged in parallel with the first swing arm 130. One end of the second swing arm 140 is rotatably connected with the mounting frame 110, and the other end of the second swing arm 140 is rotatably connected with the other end of the positioning piece 121. The elastic assembly 150 includes an elastic piece 151, which is used to provide a restoring force to the positioning piece 121 in the opposite direction of the movement direction of the workpiece transport frame 300.

[0037] Compared with the prior art, the positioning device 100 provided by the present application connects the positioning piece 121 with the mounting frame 110 by using the first swing arm 130 and the second swing arm 140, and provides a restoring force to the positioning piece 121 in the opposite direction of the movement direction of the workpiece transport frame 300 by using the elastic piece 151. Please refer to the arrows in Figure 1 and Figure 2 , Figure 1 Figure 2 ​The arrows in the figures represent the moving direction of the workpiece conveying frame 300, when the workpiece conveying frame 300 contacts with the positioning member 121, the positioning member 121 can not only displace in the moving direction of the workpiece conveying frame 300, but also displace in the direction close to the mounting frame 110, at this time, the positioning member 121 extrudes the elastic member 151, so that the elastic member 151 generates a restoring force acting on the positioning member 121 and opposite to the moving direction of the workpiece conveying frame 300, until the clamping portion clamps with the workpiece conveying frame 300, the positioning member 121 resets in the direction away from the mounting frame 110 under the action of the above-mentioned restoring force, at this time, the workpiece conveying frame 300 cannot continue to move forward without other external force, so as to accurately limit the position of the workpiece conveying frame 300 on the corresponding processing station, ensure the processing precision of the circuit board, meanwhile, avoid the contact between the circuit board and other components of the circuit board processing equipment, ensure the normal operation of the circuit board processing equipment, and improve the working reliability of the circuit board processing equipment.

[0038] In an embodiment of the present application, referring to Figure 3 The clamping portion is a first clamping slot 1211, and the first clamping slot 1211 is used for clamping the workpiece conveying frame 300 to limit the position of the workpiece conveying frame 300. Specifically, the workpiece conveying frame 300 is provided with a clamping member 310, when the clamping member 310 contacts with the positioning member 121, the positioning member 121 can not only displace in the moving direction of the workpiece conveying frame 300, but also displace in the direction close to the mounting frame 110, at this time, the positioning member 121 extrudes the elastic member 151, so that the elastic member 151 generates a restoring force acting on the positioning member 121 and opposite to the moving direction of the workpiece conveying frame 300, until the clamping member 310 of the workpiece conveying frame 300 clamps into the first clamping slot 1211, the positioning member 121 resets in the direction away from the mounting frame 110 under the action of the above-mentioned restoring force, at this time, the clamping member 310 is limited in the first clamping slot 1211, that is, the workpiece conveying frame 300 cannot continue to move forward, so as to accurately limit the position of the workpiece conveying frame 300 on the corresponding processing station.

[0039] In the above embodiment, referring to Figure 3, the positioning member 121 has a first end 1212 and a second end 1213 which are distributed in sequence along the movement direction of the workpiece conveying frame 300, the first swing arm 130 is rotatably connected with the first end 1212 of the positioning member 121, the second swing arm 140 is rotatably connected with the second end 1213 of the positioning member 121, the first clamping groove 1211 is arranged between the first end 1212 of the positioning member 121 and the second end 1213 of the positioning member 121, the first end 1212 of the positioning member 121 is provided with a first guide-in surface 12121, the first guide-in surface 12121 is arranged in a direction away from the mounting rack 110 in a direction from the first end 1212 of the positioning member 121 to the second end 1213 of the positioning member 121, in other words, after the first guide-in surface 12121 is arranged, the height (i.e. the size in the direction perpendicular to the movement direction of the workpiece conveying frame 300) of the first end 1212 of the positioning member 121 gradually increases in the direction from the first end 1212 of the positioning member 121 to the second end 1213 of the positioning member 121, in work, the clamping member 310 of the workpiece conveying frame 300 first contacts the first guide-in surface 12121, and then can quickly enter the first clamping groove 1211 under the guiding action of the first guide-in surface 12121, effectively buffering the impact force between the workpiece conveying frame 300 and the positioning member 121, so as to ensure that the circuit board processing equipment can stably run.

[0040] In the above embodiment, please refer to Figure 3 , the slot wall of the first clamping groove 1211 close to the second end 1213 of the positioning member 121 is provided with a guide-out surface 12111, the guide-out surface 12111 is arranged in a direction away from the mounting rack 110 in a direction from the first end 1212 of the positioning member 121 to the second end 1213 of the positioning member 121, in work, under the action of external driving force, the clamping member 310 of the workpiece conveying frame 300 can quickly separate from the first clamping groove 1211 along the guide-out surface 12111, further ensuring that the circuit board processing equipment can stably run.

[0041] In another embodiment of the present application, please refer to Figure 5The clamping part is a clamping block 1214, which is used to clamp the workpiece conveying frame 300 to limit the position of the workpiece conveying frame 300. Specifically, a second clamping groove (not shown in the figure) is formed on the workpiece conveying frame 300. When the workpiece conveying frame 300 contacts the positioning member 121, the positioning member 121 can not only displace in the movement direction of the workpiece conveying frame 300, but also displace in the direction close to the mounting rack 110. At this time, the positioning member 121 extrudes the elastic member 151, so that the elastic member 151 generates a restoring force acting on the positioning member 121 and opposite to the movement direction of the workpiece conveying frame 300. When the clamping block 1214 is clamped into the second clamping groove, the positioning member 121 is reset in the direction away from the mounting rack 110 under the action of the above-mentioned restoring force. At this time, under the action of no other external force, the clamping block 1214 is limited in the second clamping groove, that is, the workpiece conveying frame 300 cannot continue to move forward, so as to accurately limit the position of the workpiece conveying frame 300 on the corresponding machining station.

[0042] In the above embodiment, referring to Figure 5 The clamping block 1214 has a first side 12141 and a second side 12142 which are distributed in the movement direction of the workpiece conveying frame 300. The first side 12141 is provided with a second guide surface 12143 which is arranged to be inclined away from the mounting rack 110 in the direction from the first side 12141 to the second side 12142. In other words, after the second guide surface 12143 is arranged on the first side 12141 of the clamping block 1214, the height (i.e. the size in the direction perpendicular to the movement direction of the workpiece conveying frame 300) of the first side 12141 of the clamping block 1214 gradually increases in the direction of the second side 12142 of the clamping block 1214. In work, the workpiece conveying frame 300 first contacts the second guide surface 12143, and then the clamping block 1214 can quickly enter the second clamping groove under the guidance of the second guide surface 12143, effectively buffering the impact force between the workpiece conveying frame 300 and the clamping block 1214, so as to ensure that the circuit board processing equipment can stably operate.

[0043] In an embodiment of the present application, referring to Figure 2 The positioning assembly 120 further comprises a pressing member 122 connected to the positioning member 121, and the elastic assembly 150 further comprises a support 152 connected to the mounting rack 110. One end of the elastic member 151 abuts against the support 152, and the other end of the elastic member 151 abuts against the pressing member 122. Specifically, referring to Figure 4 The pressing member 122 comprises a connecting part 1222 and a pressing part 1223. The connecting part 1222 is connected to the positioning member 121, and the pressing part 1223 abuts against one end of the elastic member 151.

Similarly, the support 152 is detachably connected with the mounting rack 110, for example, the support 152 is connected with the mounting rack 110 in a fastening manner, or the support 152 is integrally connected with the mounting rack 110, for example, the support 152 is connected with the mounting rack 110 in a welding manner.

[0045] In the above embodiment, referring to Figure 2 The elastic assembly 150 further comprises a guide rod 153, the guide rod 153 is installed on the support 152, and the elastic member 151 is a spring, and the elastic member 151 is sleeved on the guide rod 153. By adopting the spring as the elastic member 151 and sleeving the elastic member 151 on the guide rod 153, on the one hand, the elastic member 151 can stably perform the extension and contraction movement, and on the other hand, the elastic member 151 can be prevented from being separated from the position between the pressing member 122 and the support 152, thereby ensuring the working stability of the elastic assembly 150.

[0046] It can be understood that the extension direction of the guide rod 153 is consistent with the movement direction of the workpiece conveying frame 300, and correspondingly, the extension direction of the elastic member 151 is consistent with the movement direction of the workpiece conveying frame 300; or the extension direction of the guide rod 153 and the movement direction of the workpiece conveying frame 300 form an acute angle, and correspondingly, the extension direction of the elastic member 151 and the movement direction of the workpiece conveying frame 300 form an acute angle.

In use, the initial compression amount of the elastic member 151 can be adjusted by rotating the first nut 154, so that the restoring force provided by the elastic member 151 to the positioning member 121 can be adapted to the inertia generated when the workpiece conveying frame 300 moves, thereby enabling the positioning device 100 to accurately offset the inertia of the workpiece conveying frame 300, thereby avoiding the rebound of the workpiece conveying frame 300 after contacting the positioning device 100 or the continuous movement of the workpiece conveying frame 300 under the action of inertia and the separation of the workpiece conveying frame 300 from the positioning device 100, and effectively achieving the accurate positioning of the workpiece conveying frame 300.
