Description

Technical Field

[0001] The present invention relates to the field of mechanical technology, and more particularly to a clamping and transferring device and a glue coating and weighing device. Background Art

[0002] Automotive electronic products usually have glue dispensing and potting processes. During the automated continuous production process, situations such as air mixing into the glue, wear of the glue dispensing valve, and backpressure fluctuations may occur. Therefore, the glue volume may change, and currently, the quality control of the glue volume usually adopts the methods of sampling inspection and pre-production line spot checks.

[0003] However, currently, the market has high requirements for product quality, and even requires that each product be inspected. In this way, this method does not meet the full inspection requirements of customers for high-quality products.

[0089] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0090] Reference Figure 1 、 Figure 2 and Figure 3The present invention provides a glue - applying weighing device 100, which includes a transmission track 110, a glue - applying device 170, two weighing devices 130, and two clamping and transferring devices 140. Among them, the transmission track 110 is used to convey a workpiece 1, and a loader 111 is arranged thereon. The loader 111 can move along the transmission track 110 under the action of the transmission track 110. The loader 111 has a groove for loading the workpiece 1. Preferably, the glue - applying weighing device 100 further has a control device, and this control device can be in signal connection with the transmission track 110, the glue - applying device 170, the two weighing devices 130, and the two clamping and transferring devices 140 respectively to convey various control instructions.

[0091] The glue - applying device 170 is arranged close to the transmission track 110. Preferably, the transmission track 110 can be located below the glue - applying device 170. When the loader 111 carrying the workpiece 1 moves to the position of the glue - applying device 170, the glue - applying device 170 applies glue to the workpiece 1. Exemplarily, the glue - applying device 170 can be a dispensing robot. Preferably, the dispensing component of the dispensing robot controls the glue volume through a screw valve. The dispensing robot can be a four - axis robot.

[0092] Both of the two weighing devices 130 are arranged deviating from the transmission track 110, and are respectively arranged upstream and downstream of the glue - applying device 170 along the transmission direction of the transmission track 110. Or rather, the weighing devices 130 are separated from the transmission track 110, and the weighing devices 130 and the transmission track 110 are configured as independent components. With such an arrangement, it is possible to avoid the vibration generated during transmission from affecting weighing, which is beneficial to improving the weighing accuracy.

[0093] The two clamping and transferring devices 140 are respectively arranged corresponding to the two weighing devices 130. That is to say, the glue - applying device 170 is also located between the two clamping and transferring devices 140. Preferably, the horizontal projection of the clamping and transferring device 140 at least partially covers the horizontal projections of the transmission track 110 and the weighing device 130, so that the clamping and transferring device 140 can conveniently transfer the loader 111 loaded with the workpiece 1 as a whole to the weighing device 130 for weighing.

[0094] Preferably, a stop component 112 is further arranged on the transmission track 110. The stop component 112 is configured to rise when the loader 111 loaded with the workpiece 1 approaches, so as to block the continuous transmission of the loader 111. It is easy to understand that at least three stop components 112 are arranged on the transmission track 110, corresponding to the two weighing devices 130 and the glue - applying device 170 located between them respectively.

[0095] When in continuous production, when the loader 111 loaded with the uncoated workpiece 1 is transported to the weighing device 130 upstream of the gluing device 170, it is blocked by the blocking component 112, so that the clamping transfer device 140 can transfer the loader 111 to the weighing device 130 for the first weighing. After the weighing is completed, the clamping transfer device 140 transfers the loader 111 from the weighing device 130 to the transfer track 110 for continuous transportation, and is blocked by the blocking component 112 again when it is transported to the gluing device 170. The gluing device 170 then performs gluing or dotting operations on the workpiece 1, and after completion, the loader 111 continues to be transported. When the above-mentioned loader 111 loaded with the glued workpiece 1 is transported to the weighing device 130 downstream of the gluing device 170, it is blocked by the blocking component 112, and then the corresponding clamping transfer device 140 can transfer the loader 111 to the weighing device 130 downstream for the second weighing.

[0096] After that, the control device can calculate the difference between the two weighings, so as to obtain the amount of glue applied to the workpiece 1 to determine whether the workpiece 1 is qualified. Thus, each glued workpiece 1 can be weighed and inspected twice, achieving the goal of full product inspection and effectively improving the product qualification rate.

[0097] Next, the specific structure of the clamping transfer device 140 will be introduced in detail in combination with Figures 7 to 12 First, referring to Figure 7 , the clamping transfer device 140 includes a base frame 141, a vertical moving device 163, a connecting plate 142, a rotating device 145 and a clamping device 146. Among them, the vertical moving device 163 is arranged on the base frame 141, the connecting plate 142 is connected to the vertical moving device 163, the rotating device 145 is connected to the bottom of the connecting plate 142, and the clamping device 146 is connected to the rotating device 145. The base frame 141 is preferably configured in a C shape, and its opening 139 faces the transfer track 110.

[0098] Thus, the connecting plate 142, the rotating device 145 and the clamping device 146 can move vertically (up and down) as a whole under the action of the vertical moving device 163. And the clamping device 146 can rotate under the action of the rotating device 145. It is easy to understand that the rotating device 145 can be configured as a rotating cylinder, and the vertical moving device 163 can be configured as a vertical moving cylinder.

[0099] The cross-section of the connecting plate 142 is generally L-shaped. It includes a vertical portion 144 and a horizontal portion 143. The vertical portion 144 is connected to the vertical moving device 163, and the horizontal portion 143 is disposed at the bottom of the vertical portion 144 and extends in a direction away from the vertical moving device 163. The rotating device 145 is connected to the bottom of the horizontal portion 143 of the connecting plate 142. Preferably, the connecting plate 142 also has reinforcing ribs connected to the sides of the vertical portion 144 and the horizontal portion 143.

[0100] Reference Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 ,the gripping device 146 includes a gripping cylinder 148, a gripper 147 and a connecting rod 153. The gripping cylinder 148 is connected to the bottom of the rotating device 145 via a mounting block 149. The gripper 147 is disposed on the gripping cylinder 148. The connecting rod 153 passes through the rotating device 145 and extends into the mounting block 149. The connecting rod 153 has a first gas passage 154 therein, which can communicate with the gripping cylinder 148. The first gas passage 154 is used to convey gas into the gripping cylinder 148 to drive the operation of the gripping cylinder 148, so that the gripper 147 performs a gripping action and / or a releasing action under the action of the gripping cylinder 148.

[0101] When transferring the loader 111, the gripper 147 first grips the loader 111, then rises under the action of the vertical moving device 163, then rotates under the action of the rotating device 145, descends under the action of the vertical moving device 163 after reaching the position, and finally the gripper 147 releases the loader 111, so that the loader 111 falls onto the weighing device 130. Transferring according to the above process can avoid the workpiece 1 being knocked when the gripper 147 directly rotates after gripping, which is beneficial to improving the product quality.

[0102] In the illustrated embodiment, the gripping device 146 has two gripping cylinders 148, two grippers 147, the above-mentioned mounting block 149 and an additional mounting block 150. The additional mounting block 150 is vertically connected to the bottom of the mounting block 149, and their longitudinal cross-sections are generally T-shaped ( Figure 12 as shown). Among them, the two gripping cylinders 148 are respectively connected to two opposite sides of the additional mounting block 150. Preferably, the two gripping cylinders 148 are also simultaneously connected to the bottom surface of the mounting block 149. Or rather, the two gripping cylinders 148 are disposed at two opposite corners of the mounting block 149 and the additional mounting block 150. The two grippers 147 are respectively connected to the two gripping cylinders 148 in opposite directions. A soft pad is preferably provided on each gripper 147 to prevent scratching the loader 111 and / or the workpiece 1 during gripping.

[0103] Therefore, when the loader 111 is transferred to the weighing device 130 and the loader 111 already on the weighing device 130 is weighed, the two clamps 147 can clamp the two loaders 111 at the same time and exchange their positions under the action of the rotating device 145, thereby greatly improving production efficiency.

[0104] The mounting block 149 is preferably provided with a second gas passage 151 ( Figure 9 and Figure 11 As shown), the first gas channel 154 is connected to the second gas channel 151 in the mounting block 149. A sealing ring is preferably provided at the intersection of the two to improve air tightness.

[0105] In addition, an air inlet joint 165 is provided on the side of the clamping cylinder 148, and a transition joint 152 is provided on the side of the mounting block 149. The air inlet joint 165 and the transition joint 152 can be connected via a conduit (not shown). A gas supply joint is provided on the top of the connecting rod 153, and the gas supply joint is preferably connected to an external gas source. Thus, the gas can enter the clamping cylinder 148 via the gas supply joint, the first gas channel 154, the second gas channel 151, the transition joint 152 and the air inlet joint 165 in sequence.

[0106] According to the clamping and transferring device 140 of the present invention, the connecting rod 153 passes through the rotating device 145 and is then connected to the clamping cylinder 148. In the process that the connecting rod 153 and the clamping cylinder 148 rotate together with the rotating device 145, phenomena such as pipeline entanglement and hooking can be avoided, thereby effectively ensuring the continuous production.

[0107] For the specific structure of the connecting rod 153, please refer to Figure 8 , Figure 9 and Figure 10 It includes a rod body 156, a docking portion 157, a sealing gasket 159, and a transition cover plate 161. The docking portion 157 is arranged on the top of the rod body 156, the sealing gasket 159 is arranged on the docking portion 157, and the transition cover plate 161 is arranged above the sealing gasket 159 and forms a docking with the docking portion 157.

[0108] The radial dimension of the docking portion 157 is greater than the radial dimension of the rod body 156 . The rod body 156 penetrates the horizontal portion 143 and the rotating device 145 and extends into the mounting block 149 , so that the docking portion 157 is located above the horizontal portion 143 of the connecting plate 142 .

[0109] Since the connecting rod 153 is connected to the mounting block 149, it will also rotate under the action of the rotating device 145. To limit the movement range of the connecting rod 153 and prevent the connecting rod 153 from colliding and rubbing against the rotating device 145, a groove is formed in the horizontal portion 143 of the connecting plate 142, and a bearing 158 is arranged in the groove. The rod portion of the connecting rod 153 passes through the bearing 158, so that its horizontal movement range is limited by the bearing 158.

[0110] A through hole 160 is formed in the gasket 159, and the through hole 160 corresponds to the first gas passage 154. The adapter cover plate 161 is provided with a mounting hole 162 and a passage 164. One end of the passage 164 communicates with the mounting hole 162, and the other end can lead to the through hole 160. The air supply joint 155 is at least partially arranged in the mounting hole 162. Thus, the connection between the relatively large-sized air supply joint 155 and the relatively small-sized first gas passage 154 can be realized. The gas can enter the first gas passage 154 successively through the mounting hole 162, the passage and the through hole 160.

[0111] For the specific structure of the weighing device 130, please refer to Figure 4 、 Figure 5 and Figure 6 。It includes a weighing support 131, a weighing module 132 and a positioning component 133. Among them, the weighing support 131 is separated from the transmission track 110, or it can stand independently on the ground. Preferably, the bottom of the weighing support 131 is provided with foot cups 122 to improve the vibration damping performance. The weighing support 131 is preferably welded by metal pipes, and the inside of the metal pipes is filled with sand to absorb the minute vibrations of the ground and further improve the weighing accuracy. That is, the weighing support 131 is preferably configured as a sand-filled support.

[0112] The weighing module 132 is used to weigh the loader 111. It is arranged on the top of the weighing support 131, and an anti-vibration pad 121 is arranged at its bottom to further improve the weighing accuracy. Preferably, 4 such anti-vibration pads 121 are provided to form 4 legs of the weighing module 132. The weighing module 132 is a high-precision precision weighing module.

[0113] The positioning component 133 is preferably connected to the weighing support 131 and is used to receive the loader 111 and transfer the loader 111 to the weighing module 132. Specifically, the positioning component 133 includes a horizontal adjustment component 134, a lifting device 135, a positioning plate 136 and a sensor 137. It is easy to understand that the lifting device 135 can be configured as a lifting cylinder.

[0114] The positioning plate 136 is used to receive the loader 111, and an opening 139 is formed thereon. Moreover, the weighing module 132 has a protruding sensing portion 138, and the position of the opening 139 corresponds to that of the sensing portion 138. The positioning plate 136 is arranged on the lifting device 135 to rise or fall under the action of the lifting device 135. The horizontal cross-sectional area of the sensing portion 138 is smaller than the area of the opening 139, so that the protruding sensing portion 138 of the weighing module 132 can at least partially enter the opening 139 of the positioning plate 136 to lift the loader 111 for weighing.

[0115] The horizontal adjustment assembly 134 is preferably arranged on the weighing bracket 131, and it is also connected to the lifting device 135, and is used to integrally adjust the horizontal position of the positioning assembly 133 before starting production, so that the opening 139 of the positioning plate 136 can be aligned with the sensing portion 138 of the weighing module 132.

[0116] Preferably, a sensor 137 is further arranged on the positioning plate 136 to sense whether there is a loader 111 on the positioning plate 136. Exemplarily, when the sensor 137 detects that the gripper 147 places the loader 111 on the positioning plate 136, the sensor 137 sends a signal to the control device, and the control device controls the lifting device 135 to descend for weighing.
