DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0030] like Figure 1 As shown, the utility model provides a non-powered feeding and transmission system, which cooperates with the parts processing equipment to transmit the parts raw materials. The system includes a base 1, a non-powered transmission mechanism 2, a parts blocking mechanism 3, a parts positioning mechanism 4, a base angle adjustment mechanism 5 and a robot gripper 6.

[0031] The base 1 is mainly made of parts such as support rods, and is placed on the ground to support other components in the system. One side is higher than the other side, forming a height difference to facilitate the unpowered transmission of the unpowered transmission mechanism 2.

[0032] like Figure 2 As shown, the unpowered transmission mechanism 2 is obliquely installed on the base 1, and one end is installed on the higher side of the base 1 through the base angle adjustment mechanism 5. The unpowered transmission mechanism 2 includes a bracket 21, a part direction control track 22, a part transport roller 23 and a part opening adjustment member 24. The bracket 21 is installed on the base 1, and the part direction control track 22 and the part transport roller 23 are installed on the bracket 21. The part transmission direction is formed along the height difference direction of the base 1, and the higher end of the unpowered transmission mechanism 2 is the feed port. The shapes of the part direction control track 22 and the part transport roller 23 can be set according to the shape of the part, so as to facilitate the transmission of different types of parts along the part direction control track 22. There are three part opening adjustment members 24, which are installed on the bracket 21 at intervals along the part transmission direction to adjust the accuracy of the part in place. The part transport roller 23 includes a roller bracket 230 and a rolling member 231. The roller bracket 230 is provided with a roller perpendicular to the transport roller, and the rolling member 231 is installed on the roller. The rolling member 231 shown in the figure is a cylinder.

[0033] like Figure 3As shown, the part blocking mechanism 3 is installed at the lower end of the unpowered transmission mechanism 2, and is used to block the parts sliding in along the unpowered transmission mechanism 2. It includes a blocking base 30, a first blocking rod group 31 and a second blocking rod group 32, each of the first blocking rod group 31 and the second blocking rod group 32 includes two blocking rods, and a mounting hole is provided on the blocking base 30. The first blocking rod group 31 and the second blocking rod group 32 are installed in the mounting hole and can move in the mounting hole to change the position to achieve the purpose of blocking or not blocking the parts; to ensure that there is just one part between the first blocking rod group 31 and the second blocking rod group 32, the distance between the first blocking rod group 31 and the second blocking rod group 32 is greater than or equal to the size of the part in the direction of the line connecting the first blocking rod group 31 and the second blocking rod group 32; to ensure that the first blocking rod group 31 and the second blocking rod group 32 can block the parts, the distance between the two blocking rods of each group is less than the size of the part in the direction of the line connecting the two blocking rods.

[0034] like Figure 4 As shown, the part positioning mechanism 4 is installed at the lower end of the unpowered transmission mechanism 2 and is located outside the part blocking mechanism 3. The parts in the part blocking mechanism 3 enter the part positioning mechanism 4. It includes a positioning base 40 and a part pressing block 41, a part positioning pin 42 and a part positioning block 43 installed on the positioning base 40, and also includes a part buffer sensor 44 and a part in-place sensor 45.

The shape and size of the part pressing block 41, the part positioning pin 42 and the part positioning block 43 can be designed according to the size of the part to achieve matching positioning with parts of different shapes.

[0035] like Figure 5 As shown, the base angle adjustment mechanism 5 includes an adjustment rod and an adjustment base. The adjustment rod is installed in the adjustment base to form a moving pair with the adjustment base. The adjustment base is installed on the base 1. The adjustment rod is connected to one end of the unpowered transmission mechanism 2. The transmission angle of the unpowered transmission mechanism 2 is adjusted by moving the adjustment rod.

[0036] like Figure 6 As shown, the robot gripper 6 is used to grab the parts that have been positioned on the part positioning mechanism 4.

[0037] The working principle of the utility model is as follows:

[0038] Unpowered transmission mechanism 2: Manually take parts from the material box at one time and put them into the loading port respectively. The part direction control track 22 cooperates with the part direction control, and uses the gravity of the parts to slide into the equipment through the rollers 231 on the part transport roller 23 until the parts are stacked to cover the part direction control track 22. The accuracy of the parts in place is adjusted by the part opening adjustment component 24, and a stopper light rod can also be installed on the upper side to assist in controlling the direction of part transmission. The system of the robot gripper 6 determines the remaining amount of materials in the unpowered transmission mechanism 2, and issues a material call instruction in advance according to the PLC queue, thereby eliminating the risk of downtime caused by waiting for materials.

[0039] Parts blocking mechanism 3: The first lever group 31 is initially extended into position, and parts are manually loaded. After the first part is in position, the part buffer sensor 44 has a signal, and the second lever group 32 is extended into position, and parts are manually loaded until the parts are stacked to fill the part direction control track 22;

[0040] Part positioning mechanism 4: After the second lever group 32 is extended into position, the first lever group 31 is retracted, and the part slides down to the part in-position stopper of the part positioning mechanism 4. The part in-position sensor 45 has a signal, the first lever group 31 and the part positioning pin 42 are extended into position, the second lever group 32 is retracted / the part pressing block 41 is clamped, and the next part slides down to the part blocking mechanism 3 for part caching. The part caching sensor 44 has a signal, the second lever group 32 is extended into position, and after the robot gripper 6 picks up the part, the next part goes to the picking position of the part positioning mechanism 4, and the cycle is realized once;

[0041] Robot material grabber: After the part is clamped by the part positioning mechanism 4, the material grabber takes the part into place, and after the material sensor on it recognizes a signal, the gripper chuck clamps the material and then performs the operation;

[0042] Base angle adjustment mechanism 5: adjust the mechanism adjustment rod according to the requirements of the loading machine and the gravity sliding of the parts.

[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
