Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a PCB board loading machine. Background Technology

[0002] PCB boards, or Printed Circuit Boards for short, are widely used in electronic industrial equipment. During the assembly process of electronic industrial equipment, PCB boards need to be transferred to the corresponding assembly steps. When loading PCB boards, they must first be removed from the tray before subsequent processing. In existing PCB board production processes, after completing one step, the PCB board needs to be manually picked up and placed into the next piece of equipment for the next operation. This loading efficiency is too low. Furthermore, after loading, the tray still needs to be removed. Manual operation clearly cannot meet the supply requirements of automated equipment. To improve the loading efficiency of PCB boards, and to collect the tray promptly after loading to facilitate subsequent tray loading, a PCB board loading machine is needed to solve the above problems. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a PCB board loading machine to solve the problem of maintaining efficient PCB board loading in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] A PCB board loading machine, comprising:

[0006] The material rack has a feeding compartment and a receiving compartment arranged side by side on the same side, and the feeding compartment and the receiving compartment are respectively equipped with a feeding drawer and a receiving drawer.

[0007] The feeding assembly is located on the material rack on the lower side of the feeding chamber. The feeding assembly includes a feeding base, on which a liftable top plate is disposed. The bottom of the feeding chamber is hollow. The top plate moves upward through the hollow part of the bottom of the feeding chamber to lift the material tray inside the feeding chamber to the feeding working surface.

[0008] In one embodiment of the present invention, the feeding chamber is provided in two sets, and a transverse sliding rail is provided on the material rack on the lower side of the two sets of feeding chambers. The feeding base is slidably connected to the transverse sliding rail in the horizontal direction. Each of the two sets of feeding chambers is provided with a base sensing probe on the lower side to detect the position of the feeding base on the transverse sliding rail.

[0009] In one embodiment of the present invention, a transverse drive component is provided on the material rack below the transverse slide rail, and a transverse slider is provided between the loading base and the transverse slide rail, wherein the transverse slider is in sliding engagement with the transverse slide rail.

[0010] In one embodiment of the present invention, a lifting limit seat is provided on the feeding base, the top plate is slidably connected to the lifting limit seat, and a lifting drive component is provided at the bottom of the feeding base.

[0011] In one embodiment of the present invention, a material plate base is provided between the top material plate and the lifting limit seat, the material plate base and the lifting limit seat are slidably engaged, and two sets of the ordering plates are symmetrically arranged on the material plate base.

[0012] In one embodiment of the present invention, the material rack is further provided with a drawer locking head and a locking head driving component. When the feeding drawer or receiving drawer is inserted into the feeding chamber or receiving chamber, the locking head driving component drives the drawer locking head to lock the feeding drawer or receiving drawer.

[0013] In one embodiment of the present invention, a material tray sensing probe is provided between the loading compartment and the receiving compartment at the top of the material rack to sense the height of the material trays in the loading compartment and the receiving compartment.

[0014] As described above, the PCB board loading machine of this utility model has the following beneficial effects:

[0015] 1. The top plate moves upward through the hollow part at the bottom of the loading chamber to lift the tray inside the loading chamber to the loading working surface, so that the external robot can easily grab the PCB board in the tray.

Detailed Implementation

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] Please see Figures 1 to 4 This utility model provides a PCB board loading machine, including a material rack 1 with a loading chamber 2 and a receiving chamber 3 arranged side by side on the same side. The loading chamber 2 and receiving chamber 3 are respectively equipped with a loading drawer 4 and a receiving drawer 5. The loading drawer 4 is used to hold a tray of PCB boards. An external robotic arm picks up the PCB boards from the tray. After the tray is emptied, the robotic arm picks up the empty tray and places it in the receiving drawer 5, thus recycling the tray. The loading assembly is located on the material rack 1 below the loading chamber 2. The loading platform 6 is equipped with a liftable top plate 7. The bottom of the loading chamber 2 is hollow. The top plate 7 moves upward and passes through the hollow part at the bottom of the loading chamber 2 to lift the tray in the loading chamber 2 to the loading working surface, so that the external robot can easily grab the PCB board in the tray. After the tray is grabbed to the receiving drawer 5, the top plate 7 continues to move upward to lift the next layer of tray to the gripping working surface of the robot, so as to facilitate the subsequent gripping of the PCB board.

[0025] The feeding chamber 2 is provided with two sets. A transverse slide rail 8 is set on the material rack 1 on the lower side of the two sets of feeding chambers 2. The transverse slide rail 8 guides and limits the transverse movement of the feeding base 6, thereby improving the stability of the feeding base 6 during transverse movement. The feeding base 6 is slidably connected to the transverse slide rail 8 in the horizontal direction. When all the material trays in one set of feeding chambers 2 are used up, the top plate 7 moves downward to the lower side of the feeding chamber 2. Then the feeding base 6 moves laterally to the lower side of the other feeding chamber 2 to continue the feeding and lifting action. Each set of feeding chambers 2 is provided with a base sensing probe 9 to detect the position of the feeding base 6 on the transverse slide rail 8.

[0026] A transverse drive component 10 is provided on the material rack 1 below the transverse slide rail 8. The transverse drive component 10 drives the loading platform 6 to move laterally. A transverse slider 11 is provided between the loading platform 6 and the transverse slide rail 8. The transverse slider 11 slides with the transverse slide rail 8 to improve the stability of the loading platform 6 during the transverse movement.

[0027] A lifting limit seat 12 is provided on the feeding platform 6. The lifting limit seat 12 can guide the lifting movement of the top plate 7. A lifting drive component 13 is provided at the bottom of the feeding platform 6, which can reduce the occupation of the lifting drive component 13 in the lifting space, making the equipment layout more reasonable. A material plate base 14 is provided between the top plate 7 and the lifting limit seat 12. Two sets of top plates 7 are symmetrically arranged on the material plate base 14. By using two sets of top plates 7, the lifting action of the material tray can be more stable and reliable.

[0028] The material rack 1 is also equipped with a drawer locking head 15. When the feeding drawer 4 or the receiving drawer 5 is inserted into the feeding chamber 2 or the receiving chamber 3, the locking head drive component 16 drives the drawer locking head 15 to move closer to the drawer, thereby pressing the drawer locking head 15 against the root of the drawer to lock the feeding drawer 4 or the receiving drawer 5.

[0029] A material tray sensing probe 17 is installed between the loading chamber 2 and the receiving chamber 3 at the top of the material rack 1 to sense the height of the material trays in the loading chamber 2 and the receiving chamber 3, thereby controlling the lifting drive component 13 to adjust the lifting height of the top plate 7.

[0030] The front of the feeding drawer 4 or receiving drawer 5 is also equipped with indicator lights. Different indicator lights are displayed according to the status of the material tray in the feeding drawer 4 or receiving drawer 5, so as to remind the operator to replenish the material tray in the feeding drawer 4 in time or replace the receiving drawer 5.

[0031] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
